The comparator receives the second audio signal from the processor and the comparator receives the reference signal from the signal generator.

Detailed Description

In the following embodiments of the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a alone, b alone, or c alone, may represent: a alone, b alone, c alone, a and b in combination, a and c in combination, b and c in combination, or a, b and c in combination, wherein a, b and c may be single or multiple. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Currently, as shown in fig. 1, the rotor motor includes various types, such as a cylindrical motor and a brushless motor, and their internal structures are different, but the internal structures all have three types: coil, magnet steel and eccentric oscillator. The magnetic steel is used for providing a magnetic field, when the coil is electrified with direct current, a current-carrying conductor of the coil can be acted by electromagnetic force in the magnetic field, the moment formed by the electromagnetic force can enable the eccentric vibrator to rotate around the rotor, the eccentric vibrator can generate centripetal force at the moment, and the motor is slightly displaced by the centripetal force, so that the vibration effect is generated.

Based on the foregoing description, the motor is rotated by the magnetic force in the magnetic field generated by the coil. Formula based on driving force F: F-BIL, the magnetic field B and the coil L are both constant. When the voltage supplied to the motor is larger, the current I is larger, the driving force F is larger, the rotating speed of the eccentric vibrator is higher, and the vibration acceleration provided by the motor is larger.

Next, based on the above-described motor vibration principle, an example of realizing vibration and stopping vibration of a conventional rotor motor will be described.

In the related art 1, a low dropout regulator (LDO) built in a Power Management Unit (PMU) is used to supply power to the rotor motor, so as to realize vibration and stop vibration of the rotor motor. As shown in fig. 2a, the positive pole of the rotor motor (indicated by the "+" symbol in fig. 2 a) is electrically connected to the output terminal OUT of the LDO, and the negative pole of the rotor motor (indicated by the "-" symbol in fig. 2 a) and the ground terminal of the LDO are both electrically connected to the common ground of the power management unit PMU. As shown in fig. 2b, when the LDO outputs a dc voltage to the rotor motor (illustrated by 3V in fig. 2b as an example), the rotor motor starts to oscillate. Wherein, 3V is the rated voltage of the rotor motor, namely, the rotor motor can start oscillation when being supplied with 3V. When the LDO output to the rotor motor is off (illustrated in fig. 2b with 0V as an example), the rotor motor is stopped by its own damping.

Based on this, the vibration starting time period T1 and the vibration stopping time period T2 of the rotor motor are dragged by the vibration sensation, and the effects of rapid vibration and rapid vibration stopping cannot be achieved. Generally, the term ERM for a single cell is about 180 milliseconds (ms) and about 180 ms. For example, if vibration of the main page key of the mobile phone needs to be realized by using the related art 1, the vibration starting time T1 of the rotor motor is about 60ms, and the vibration stopping time T2 of the rotor motor is about 130ms, so that the total vibration time of the rotor motor is about 190ms, fast vibration and fast stop vibration cannot be realized, and the user experience is poor.

In addition, for the scene that the pressing vibration needs to be realized on the electronic device, the LDO needs to output a sufficiently long dc voltage to the rotor motor, so that a user can only give a comfortable vibration amount, and at this time, the start-up time and the stop time of the rotor motor are longer, which is more disadvantageous to the realization of the rapid vibration and the rapid stop vibration of the rotor motor.

In the related art 2, a Pulse Width Modulation (PWM) driver built in a power management unit PMU is used to supply a high frequency PWM signal to the rotor motor to realize rapid vibration and rapid stop vibration of the rotor motor.

As shown in fig. 3a, the positive pole of the rotor motor (indicated by the "+" sign in fig. 3 a) is electrically connected to the positive output terminal OUT1 of the PWM driver, and the negative pole of the rotor motor (indicated by the "-" sign in fig. 3 a) is electrically connected to the negative output terminal OUT2 of the PWM driver.

Based on the connection relationship of fig. 3a, as shown in fig. 3b, when the PWM driver outputs the first PWM signal to the rotor motor (the first PWM signal is illustrated by 5V with a duty ratio of 100% in fig. 2 b), since the amplitude of the driving voltage (i.e. 5V) is much higher than the amplitude of the rated voltage of the rotor motor (i.e. 3V), the rotor motor can start to vibrate at a faster speed, and a fast vibration starting effect can be achieved. After a period of time, for example, 50ms, when the PWM driver outputs the second PWM signal to the rotor motor (the second PWM signal in fig. 3b is illustrated as 5V with a duty ratio of 60%), the actual voltage received by the rotor motor becomes 5V × 60% — 3V, so that the rotor motor continues to vibrate, and the rotor motor is guaranteed to vibrate for a long time. When the PWM driver outputs the third PWM signal to the rotor motor (illustrated in fig. 3b by taking-5V with a duty ratio of 100%) as an example), since the driving voltage (i.e., 5V) is smaller than the rated voltage (i.e., 3V) of the rotor motor and the amplitude of the driving voltage (i.e., 5V) is much higher than the amplitude of the rated voltage (i.e., 3V) of the rotor motor, the rotor motor stops vibrating, so that the effect of stopping vibrating rapidly can be achieved. The duty ratio of the third PWM signal may also adopt other values than 100%, and it is only necessary that the phases of the third PWM signal and the first PWM signal are in opposite phase. It should be noted that, in addition to the above manner, the rotor motor may stop vibrating quickly after vibrating quickly, and the rotor motor does not need to vibrate for a long time.

Based on this, in order to ensure that the voltage received by the rotor motor at the time of starting and stopping vibration is 3V or more, the PWM driver needs to equate the high voltage to the low voltage, i.e., from 5V to 3V, by controlling the duty ratio. Thus, there are special requirements on the frequency of the PWM driver. The reason is that: if the PWM driver frequency is low, the rotor motor will have a surge sound. If the frequency of the PWM driver is high, the vibration sound of the rotor motor is normal, but the requirement for the PWM driver is too high at the moment, and the frequency of the PWM driver is generally required to be more than 20 kHz. In addition, the PWM driver switches the voltage back and forth, and the rotor motor is directly electrically connected to the PWM driver, which may adversely affect the life of the rotor motor.

In order to solve the above problems, the present application provides a method for controlling vibration of an electronic device, an Audio Codec (Audio Codec) and an Audio Codec, which can generate a PWM signal with a duty ratio close to 100% or equal to 100% by using an Audio signal, that is, a waveform of the PWM signal is a dc voltage waveform, and further, a dc driving voltage can be obtained by amplifying and filtering the PWM signal, and then the rotor motor is driven by the dc driving voltage, so that not only is fast start-up and fast stop of the rotor motor realized, but also the life of the rotor motor is not affected by supply of dc power, and the rotor motor is protected. In addition, the waveform of the PWM signal is consistent with that of the audio signal, different vibration effects of the rotor motor can be realized through different settings of the audio signal, and the requirements of different use scenes, such as key vibration, reminding vibration and the like, of the electronic equipment can be met.

The electronic device may include, but is not limited to, a mobile phone, a tablet computer, an electronic reader, a remote controller, a Personal Computer (PC), a notebook computer, a Personal Digital Assistant (PDA), a vehicle-mounted device, a web tv, a wearable device, a television, a smart watch, a smart bracelet, and other devices that need to implement vibration.

The method for controlling the vibration of the electronic equipment is suitable for reminding a user of using scenes, such as new messages (short messages, multimedia messages or instant messaging messages and the like), new calls, alarm reminding, memorandum reminding and the like received by a mobile phone, can also be suitable for using scenes of keys, such as vibration of a rotor motor when the user touches a main page key of the mobile phone or vibration of the rotor motor when the user keys the mobile phone, and can also be suitable for vibration in entertainment applications such as games and the like.

The technical solution of the present application will be described in detail with reference to specific examples.

Fig. 4 is a schematic structural diagram of an electronic device according to an embodiment of the present application. As shown in fig. 4, the electronic device 1 of the present application may include: a processor 10, an audio codec module 20, and a rotator motor 30.

In an embodiment of the present application, an output end of the processor 10 is electrically connected to a control end of the audio codec module 20, so that the processor 10, as an audio signal source of the audio codec module 20, can send an audio signal to the audio codec module 20, where the audio signal is used to drive the rotator motor 30 to vibrate rapidly and stop vibrating rapidly.

The processor 10 may be an integrated chip, such as a system on chip (SoC), or may be formed by combining a plurality of components, or may be formed by combining an integrated chip and a peripheral circuit, which is not limited in the following embodiments of the present application.

In addition, the present application does not limit parameters such as the number of audio signals, waveforms, or periods. In some embodiments, the audio signal may be at least one of a triangular wave, a saw-tooth wave, a rectangular wave, or a sine wave. The audio signal may be pre-stored in the electronic device 1, may also be stored in the electronic device 1 by a user, and may also be stored in the electronic device 1 by combining the foregoing two manners, which is not limited in this application.

In the present application, the output end of the audio codec module 20 is electrically connected to the rotor motor 30, so that the audio codec module 20 serves as a power supply source of the rotor motor 30, and based on the reference signal and the audio signal, and an effective amplitude (RMS) of the reference signal is smaller than an effective amplitude of the audio signal, the audio codec module can supply a direct current to the rotor motor 30 to drive the rotor motor 30 to vibrate rapidly or stop vibrating rapidly. It should be noted that the effective amplitude of the signal can also be understood as the gain of the signal.

Among them, the audio codec module 20 may generate a reference signal for the audio codec module 20 to compare the audio signal with the reference signal and drive the rotator motor 30 to vibrate fast and stop vibrating fast using the compared signal. The present application does not limit parameters such as the waveform and the period of the reference signal. In some embodiments, the reference signal may be at least one of a triangular wave, a sawtooth wave, a rectangular wave, or a sine wave. And the number or type of the rotor motors 30 and the like are not limited in the present application. In addition, the audio codec module 20 may also supply power to the processor 10 so that the processor 10 can operate normally.

The audio codec module 20 may adopt software and/or hardware to implement the fast vibration and fast stop of the rotor motor 30, and the specific implementation structure of the audio codec module 20 is not limited in this application. For example, the audio codec module 20 may be formed by a single chip, a plurality of chips electrically connected to each other, a combination of chips and components, or a plurality of components connected to each other. In addition, the audio codec module 20 may be separately provided, or may be built in a power management unit PMU of the electronic device 1 (as shown in fig. 4 b), and the power management unit PMU supplies power to the audio codec module 20 through a battery in the electronic device 1, which is not limited in this application.

Audio codec module 20 in some embodiments, as shown in fig. 5a, the audio codec module 20 of the present application may include: a signal generator 201, a comparator 202 and a power amplifier 203.

The signal generator 201 is configured to output the reference signal. A first input terminal of the comparator 202 is electrically connected to the output terminal of the signal generator 201, a second input terminal of the comparator 202 is electrically connected to the output terminal of the processor 10, the comparator 202 is configured to receive the audio signal from the processor 10, an output terminal of the comparator 202 is electrically connected to an input terminal of the power amplifier 203, and an output terminal of the power amplifier 203 is electrically connected to the rotator motor 30.

Based on the electrical connection relationship, the signal generator 201 performs PWM sampling on the audio signal through the comparator 202. Since the effective amplitude of the reference signal is smaller than the effective amplitude of the audio signal, the comparator 202 can output the PWM signal with a duty ratio close to 100% or equal to 100%, that is, the waveform of the PWM signal is a dc voltage waveform, and the waveform of the PWM signal is consistent with the waveform of the audio signal. Since the amplitude of the PWM signal generally cannot satisfy the amplitude of the rated voltage of the rotor motor 30 and cannot satisfy the driving capability of the rotor motor 30, the PWM signal needs to pass through the power amplifier 203 and then becomes a direct current driving voltage, the amplitude of the driving voltage is greater than the amplitude of the rated voltage of the rotor motor 30, and the phase of the driving voltage may be in-phase or in-phase with the phase of the rated voltage of the rotor motor 30, that is, the phase of the vibration voltage driving the rotor motor 30 and the phase of the driving voltage driving the rotor motor 30 to stop vibrating are in-phase. Accordingly, not only the magnitude of the driving voltage but also the driving current transmitted to the rotor motor 30 are enhanced to enhance the driving capability of the rotor motor 30, thereby supplying the driving voltage of the direct current to the rotor motor 30, so that the rotor motor 30 vibrates or stops vibrating.

The present application does not limit the specific types or numbers of the signal generator 201, the comparator 202, and the power amplifier 203. For example, the signal generator 201, the comparator 202, and the power amplifier 203 may be implemented by a single chip, may be implemented by connecting a plurality of components, or may be implemented by combining a chip and a component, which is not limited in this application. In addition, at least two of the signal generator 201, the comparator 202, and the power amplifier 203 may be provided using an integrated chip. For example, the signal generator 201 and the comparator 202 may be integrally provided as separate chips. Generally, the power amplifier 203 may be selected from the class D power amplifier 203 or the class K power amplifier 203. In addition, for the PWM signal whose duty ratio mentioned in the present application is close to 100% or equal to 100%, a preset range of the duty ratio of the PWM signal may be set between 90% or more and 100% or less, and the preset range may be a first preset range or a second preset range mentioned later.

In addition, as shown in fig. 5b, the audio coding and decoding module 20 may further include: and a filter 204, wherein an input end of the filter 204 is electrically connected to an output end of the power amplifier 203, and an output end of the filter 204 is electrically connected to the rotor motor 30. The present application does not limit the specific type or number of the filters 204. For example, the filter 204 may be a low pass filter or a band pass filter.

Since the driving voltage inevitably introduces high-frequency noise interference, the driving voltage may be changed into a direct-current driving voltage with less noise interference or no noise after passing through the filter 204, so as to supply the direct-current driving voltage to the rotor motor 30, so that the rotor motor 30 vibrates or stops vibrating, and the effect of the rotor motor 30 vibrating or stopping vibrating is improved.

With continued reference to fig. 5b, the audio codec module 20 may further include a switch bridge 205, the switch bridge 205 is electrically connected between the filter 204 and the rotator motor 30, and the switch bridge 205 is used to adjust the phase of the driving voltage for driving the rotator motor 30 and the driving voltage for driving the rotator motor 30 to stop vibrating to be opposite. The present application does not limit the specific type or number of the switch bridge 205.

When the audio codec module 20 includes the switch bridge 205, since the switch bridge 205 can change the phase of the voltage, the phases of the audio signal corresponding to the vibration of the driving rotor motor 30 and the audio signal for stopping the vibration of the driving rotor motor 30 can be in the same phase or in opposite phases, and it is only necessary to ensure that the phase of the driving voltage for driving the vibration of the rotor motor 30 and the phase of the start-up voltage or the rated voltage of the rotor motor 30 are in the same phase, and the phase of the driving voltage for stopping the vibration of the rotor motor 30 and the phase of the start-up voltage or the rated voltage of the rotor motor 30 are in opposite phases.

For convenience of illustration, a specific implementation process of the comparator 202 in the audio codec module 20 generating the PWM signal by comparing the reference signal and the audio signal is illustrated in conjunction with fig. 6 a. In fig. 6a, the abscissa is time t and the ordinate is voltage U. The reference signal is a triangular wave and is illustrated by curve 1 as an example. The audio signal is a sine wave with a period T and is illustrated by taking curve 2 as an example. The PWM signal generated on the basis of the audio signal and the reference signal is illustrated by way of example in curve 3.

As shown in fig. 6a, the comparator 202 in the audio codec module 20 may generate the PWM signal by comparing the audio signal with the reference signal, and the maximum amplitude of the PWM signal is U and the minimum amplitude is 0V. On the one hand, the duty ratio of the PWM signal is close to 100% as a whole, that is, the waveform of the PWM signal is a dc voltage waveform. On the other hand, when the audio signal is in the positive half axis of one period T, the amplitude U in the PWM signal occupies a large portion. When the audio signal is at the negative half-axis of one period T, the amplitude of the PWM signal is 0V for the most part. It can be seen that the waveform of the PWM signal is consistent with the waveform of the audio signal.

Based on the operation principle of the comparator 202 in the audio codec module 20, as shown in fig. 6b, the minimum value of the effective amplitude of the audio signal is set to be greater than the effective amplitude of the reference signal, so that the comparator 202 in the audio codec module 20 can output the PWM signal with a duty ratio close to 100% or equal to 100%.

The amplitude of the PWM signal may increase with the increase of the gain of the power amplifier 203 in the audio codec module 20, and the amplitude of the PWM signal may also increase with the increase of the effective amplitude of the audio signal.

Next, referring to fig. 6b, when the minimum value of the effective amplitude of the audio signal is greater than the effective amplitude of the reference signal, a specific implementation process of the comparator 202 in the audio codec module 20 generating the PWM signal by comparing the reference signal and the audio signal will be illustrated.

In fig. 6b, the abscissa is time t and the ordinate is voltage U. The reference signal is a triangular wave and is illustrated by curve 1 as an example. The audio signal comprises an audio signal 1 and an audio signal 2, and the effective amplitude of the audio signal 1 is larger than that of the audio signal 2. The audio signal 1 is a sine wave with a period T and is illustrated by way of example by the curve 21. The audio signal 2 is a sine wave with a period T' and is illustrated by way of example by the curve 22.

As shown in fig. 6b, the comparator 202 may generate a PWM signal 1 based on the audio signal 1 and the reference signal, which is illustrated by the curve 31 as an example. The comparator 202 may generate a PWM signal 2 based on the audio signal 2 and the reference signal, which is illustrated by the curve 32. And it is easy to see that the PWM signal 1 and the PWM signal 2 are both direct current voltages, and the amplitude of the PWM signal 1 is greater than the amplitude of the PWM signal 2.

Based on the electronic device 1 shown in fig. 4-6 b, a detailed description is given to a specific implementation process of the method for controlling the vibration of the electronic device 1 according to the present application, in conjunction with the following embodiments.

Fig. 7a is a flowchart illustrating a method for controlling vibration of an electronic device according to an embodiment of the present application. As shown in fig. 7a, the method for controlling the vibration of the electronic device 1 of the present application may include:

s101, when receiving a first trigger command, the processor sends a first audio signal to the audio coding and decoding module, wherein the first trigger command is used for indicating the rotor motor to vibrate through the first audio signal.

In the present application, the upper application of the electronic device 1 may respond to an operation entered by the user, where the operation is used to trigger the electronic device 1/the rotor motor 30 to vibrate, and the operation includes, but is not limited to, clicking, double clicking, long pressing, screenshot, etc., and may also respond to an event built in the electronic device 1, where the event is used to trigger the electronic device 1/the rotor motor 30 to vibrate, and the event may be a triggered event such as a timer or a timer in the electronic device 1, so as to generate the first trigger command and issue the first trigger command to the processor 10.

The first trigger command may be a digital signal or an analog signal, which is not limited in this application. The specific representation form of the first trigger command is not limited in the present application. For example a vibranteon command for instructing the electronic device 1/rotor motor 30 to vibrate.

In response to a first trigger command of the electronic device 1, based on the electrical connection relationship between the processor 10 and the audio codec module 20, the processor 10 may send a first audio signal to the audio codec module 20, where the first audio signal is used for the audio codec module 20 to supply direct current to the rotator motor 30.

The present application does not limit parameters such as the number, waveform, or period of the first audio signal. In some embodiments, the first audio signal may be at least one of a triangle wave, a sawtooth wave, a rectangular wave, or a sine wave. The first audio signal may be stored in the electronic device 1 in advance, may also be stored in the electronic device 1 by a user, and may also be stored by combining the foregoing two manners, which is not limited in this application.

S102, the audio coding and decoding module drives the rotor motor to vibrate based on the first audio signal and the reference signal, wherein the minimum value of the effective amplitude of the first audio signal is greater than the effective amplitude of the reference signal.

Since the minimum value of the effective amplitude of the first audio signal is greater than the effective amplitude of the reference signal, the audio codec module 20 may output the first PWM signal having a duty ratio within a first preset range (i.e., close to 100% or equal to 100%) by comparing the first audio signal with the reference signal, that is, the waveform of the first PWM signal is a dc voltage waveform, and the waveform of the first PWM signal is consistent with the waveform of the first audio signal. Thus, the audio codec module 20 may control whether the rotator motor 30 vibrates and the vibration condition by the processor 10 adjusting the first audio signal.

Therefore, the audio codec module 20 may amplify and filter the first PWM signal to obtain a dc first driving voltage, where the amplitude of the first driving voltage is greater than or equal to the amplitude of the rated voltage of the rotor motor 30, and the phases of the first driving voltage and the rated voltage of the rotor motor 30 are in the same phase. Based on the electrical connection relationship between the audio codec module 20 and the rotor motor 30, the audio codec module 20 may provide a first dc driving voltage to the rotor motor 30, so that the rotation speed of the rotor motor 30 is rapidly increased, and the rotor motor 30 is driven to start vibrating, thereby achieving the effect of rapidly starting vibrating the rotor motor 30 and shortening the vibration starting time of the rotor motor 30.

S103, when receiving a second trigger command, the processor sends a second audio signal to the audio coding and decoding module, wherein the second trigger command is used for indicating the rotor motor to stop vibrating, and the effective amplitude of the second audio signal is larger than that of the reference signal.

In other embodiments, the upper application of the electronic device 1 may respond to the user's key input operation, which is used to trigger the electronic device 1/rotator motor 30 to stop vibrating, and the operation includes but is not limited to clicking, double clicking, long pressing, screenshot, etc., and may also respond to an event built in the electronic device 1, which is used to trigger the electronic device 1/rotator motor 30 to stop vibrating, and the event may be a triggered event such as a timer or timer in the electronic device 1, to generate the second trigger command, and issue the second trigger command to the processor 10.

The second trigger command may be a digital signal or an analog signal, which is not limited in this application. And the specific representation form of the second trigger command is not limited in the application. For example a vibranteoff command for instructing the electronic device 1/rotor motor 30 to stop vibrating.

In response to a second trigger command of the electronic device 1, based on the electrical connection relationship between the processor 10 and the audio codec module 20, the processor 10 may send a second audio signal to the audio codec module 20, where the second audio signal is used for the audio codec module 20 to stop supplying power to the rotator motor 30.

The present application does not limit parameters such as the waveform or the period of the second audio signal. In some embodiments, the second audio signal may be at least one of a triangular wave, a sawtooth wave, a rectangular wave, or a sine wave. The second audio signal may be stored in the electronic device 1 in advance, may also be stored in the electronic device 1 by a user, and may also be stored by combining the foregoing two manners, which is not limited in this application.

It should be noted that the present application does not limit the effective amplitude and phase of the first audio signal and the second audio signal.

When the phases of the first and second audio signals are in phase, the phase of the first driving voltage generated based on the first audio signal is adjusted by the switching bridge 215 in the audio codec module 20 such that the phase of the first driving voltage is in phase with the phase of the start-up voltage or the rated voltage of the rotor motor 30, and the phase of the second driving voltage generated based on the second audio signal is adjusted by the switching bridge 215 in the audio codec module 20 such that the phase of the second driving voltage is in anti-phase with the phase of the start-up voltage or the rated voltage of the rotor motor 30.

When the phases of the first and second audio signals are inverted, the phase of the first driving voltage generated based on the first audio signal is adjusted by the switching bridge 215 in the audio codec module 20 such that the phase of the first driving voltage is in phase with the phase of the start-up voltage or the rated voltage of the rotor motor 30, and the phase of the second driving voltage generated based on the second audio signal is adjusted by the switching bridge 215 in the audio codec module 20 such that the phase of the second driving voltage is inverted with respect to the phase of the start-up voltage or the rated voltage of the rotor motor 30. And S104, the audio coding and decoding module drives the rotor motor to stop vibrating based on the second audio signal and the reference signal.

Since the effective amplitude of the second audio signal is greater than the effective amplitude of the reference signal, the audio codec module 20 may output the second PWM signal having a duty ratio within a second preset range (i.e., close to 100% or equal to 100%) by comparing the second audio signal with the reference signal, that is, the waveform of the second PWM signal is a dc voltage waveform.

Accordingly, the audio codec module 20 may amplify and filter the second PWM signal to obtain the second driving voltage of the direct current, and the phase of the second driving voltage and the rated voltage of the rotor motor 30 is opposite, that is, the phase of the first driving voltage and the second driving voltage is opposite. Based on the electrical connection relationship between the audio codec module 20 and the rotor motor 30, the audio codec module 20 may provide a dc second driving voltage to the rotor motor 30, so that the rotation speed of the rotor motor 30 is rapidly decreased, the rotor motor 30 is driven to stop vibrating, the effect of rapidly stopping vibrating of the rotor motor 30 is achieved, and the vibration stopping time of the rotor motor 30 is shortened.

The specific magnitude of the amplitude of the second driving voltage is not limited in the present application. In some embodiments, to cause the gerotor motor 30 to stop vibrating quickly, the effective amplitude of the second audio signal is at a maximum of the effective amplitude of the first audio signal, such that the amplitude of the second drive voltage is equal to the maximum of the amplitude of the first drive voltage.

It should be noted that, based on the descriptions of S101-S102, the audio codec module 20 may drive the rotor motor 30 to vibrate based on the first audio signal. In the vibration process of the rotator motor 30, if the processor 10 does not receive the second trigger command, the audio codec module 20 cannot receive the new first audio signal, and therefore, the audio codec module 20 may drive the rotator motor 30 to continue driving based on part or all of the received first audio signal until the processor 10 receives the second trigger command, where specific content of the second trigger command may be referred to in the foregoing description, and is not described herein again.

In contrast to the related art 1, the present application does not rely on the self-damping of the rotor motor 30 to stop the vibration, and does not directly supply the continuous dc voltage to the rotor motor 30.

Next, the effects of the rotor motor in the related art 1 and the rotor motor 30 in the present application of achieving vibration and stopping vibration will be described with reference to fig. 7 b. In fig. 7b, the abscissa represents time t, and the ordinate represents the rotational speed v of the rotor motor 30.

As shown in fig. 7b, the solid line corresponds to the rotor motor 30 in the present application achieving vibration and stopping vibration, and the broken line corresponds to the rotor motor in the related art 1 achieving vibration and stopping vibration. The rotary motor may vibrate assuming that the rotational speed of the rotary motor reaches v 1. In the present application, the rotational speed of the rotor motor 30 can reach v1 after the time period T1 ', that is, the vibration starting time period of the rotor motor 30 is T1'. In the related art 1, the rotation speed of the rotor motor reaches v1 after the time period T1 elapses, that is, the oscillation starting time period of the rotor motor 30 is T1. As can be seen by FIG. 7b, T1' is less than T1. In general, if vibration of the main keys of the mobile phone is to be realized in the related art 1, the start-up time period T1 of the rotator motor is about 60ms, and the start-up time period T1' of the rotator motor 30 of the present application is about 40 ms.

It is understood by those skilled in the art that the rotor motor stops vibrating when the rotational speed of the rotor motor is 0. In the present application, the rotation speed of the rotor motor 30 may be changed from v1 to 0 after the elapse of the time period T2 ', that is, the vibration stop time period of the rotor motor 30 is T2'. In the related art 1, the rotation speed of the rotor motor can be changed from v1 to 0 after the elapse of the time period T2, that is, the vibration stop time period of the rotor motor 30 is T2. As can be seen by FIG. 7b, T2' is less than T2. In general, if vibration of the main keys of the mobile phone is to be realized by the related art 1, the vibration stop time period T2 of the rotor motor is about 130ms, and the vibration stop time period T2' of the rotor motor 30 of the present application is about 20 ms.

In contrast to the related art 2, the rotor motor 30 of the present application is not limited by the frequency of the PWM driver, and the life of the rotor motor 30 is not affected by the PWM driver. In the present application, the effective amplitude of the audio signal is greater than the effective amplitude of the reference signal, so that it can be ensured that the duty ratio of the PWM signal is close to 100% or equal to 100%, that is, the audio codec module 20 can output the dc driving voltage to the rotor motor 30, thereby realizing the rapid vibration and rapid stop vibration of the rotor motor 30, and the supply of the dc power is beneficial to prolonging the service life of the rotor motor 30, and playing a role in protecting the rotor motor 30. And the waveform of the driving voltage is consistent with the waveform of the audio signal, so that the waveform of the audio signal is adjusted by the processor 10, and the audio codec module 20 can control whether the rotator motor 30 vibrates and the vibration condition, so that the rotator motor 30 has different vibration effects, and the electronic device 1 is favorably applied to different use scenes to bring different special effect vibration experiences to users. In a specific embodiment, for convenience of description, in the following, the electronic device 1 takes a mobile phone as an example, and with reference to fig. 8a to 8b, a configuration process of performing a vibration effect on a use scene in which the mobile phone vibrates when a new incoming call is received and a specific implementation process of vibrating the mobile phone when the new incoming call is received are described.

As shown in fig. 8a, the display screen of the mobile phone includes an icon of the text "none", an icon of the text "vibration effect 1", an icon of the text "vibration effect 2", an icon of the text "vibration effect 3", and an icon of the text "vibration effect 4".

Wherein the icon of the word "none" does not correspond to any vibration effect. Taking the starting vibration voltage of the rotor motor 30 as 1V and the rated voltage of the rotor motor 30 as 3V as an example, the icon of the character "vibration effect 1" corresponds to the vibration effects generated by the audio 1 and the audio 5, and the vibration effect corresponding to the audio 1 is: the vibration was carried out for 30ms at a driving voltage of 5V and for 20ms at a driving voltage of 3V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon for the word "vibration effect 2" corresponds to the vibration effect produced by audio 2 and audio 5, with audio 2 corresponding to the vibration effect: vibrate for 30ms at a driving voltage of 5V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon for the word "vibration effect 3" corresponds to the vibration effect produced by audio 3 and audio 5, with audio 3 corresponding to the vibration effect: the vibration was carried out for 20ms at a driving voltage of 5V and for 30ms at a driving voltage of 2V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon for the word "vibration effect 4" corresponds to the vibration effect produced by audio 4 and audio 5, with audio 4 corresponding to the vibration effect: the vibration was carried out for 20ms at a driving voltage of 5V, for 30ms at a driving voltage of 2V, and for 10ms at a driving voltage of 4V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V.

Audio 1, audio 2 and audio 5 are pre-stored in the factory. The audio 3 and the audio 4 are stored in the mobile phone by the user in a network downloading or Bluetooth transmission mode. And audio 1, audio 2, audio 3 and audio 4 are all first audio signals for driving the rotor motor 30 to vibrate. Tone 5 is a second tone signal for driving the rotor motor 30 to stop vibrating.

When a new incoming call is made, the vibration effect is not configured in the use scene of the mobile phone in which vibration occurs, at the moment, the opposite hook image is displayed at the position corresponding to the image of the character 'none', and the vibration icon 71 is stopped being displayed on the upper right corner of the mobile phone. If the user wants to configure the vibration effect 1 for the usage scenario in which the mobile phone vibrates when there is a new incoming call, as shown in fig. 8a, the user may enter an operation for triggering the rotor motor 30 to vibrate on the mobile phone, for example, click the position corresponding to the icon of the word "vibration effect 1" on the mobile phone, at this time, the position corresponding to the icon of the word "vibration effect 1" displays the opposite-hook icon, the position corresponding to the image of the word "none" disappears, and the display stop vibration icon 71 on the upper right corner of the mobile phone is changed to display the vibration icon 72.

Thus, based on the description of S101-S104, the cellular phone may respond to the click operation, so that the cellular phone drives the rotator motor 30 to vibrate rapidly based on the audio 1, so that the user can perceive the vibration effect 1. If the user has an operation of typing in to stop the rotator motor 30 from vibrating within 50ms from the start of the vibration of the rotator motor 30, the cellular phone drives the rotator motor 30 to rapidly stop the vibration based on the audio 6. On the contrary, after the rotor motor 30 vibrates for 50ms, the cellular phone drives the rotor motor 30 to rapidly stop vibrating based on the audio 6.

In summary, the user can set the vibration effect 1 as the vibration effect corresponding to the usage scenario in which the mobile phone vibrates when there is a new incoming call. It should be noted that the user may also configure other vibration effects for the usage scenario in which the mobile phone vibrates when there is a new incoming call, and the specific implementation process is the same as the implementation process for configuring the vibration effect 1, which can be referred to the above description, and is not described herein again. Therefore, the personalized setting of the user is facilitated, the user can select the corresponding vibration effect based on different use scenes, for example, the user can select the vibration effect applied to the outdoor mode to have stronger vibration sense or longer vibration duration, or the user can select the vibration effect applied to the office mode to have weaker vibration or shorter vibration duration.

As shown in fig. 8b, based on the above-mentioned setup process of fig. 8a, the mobile phone has configured the vibration effect 1 in the usage scenario where vibration occurs when there is a new incoming call, and at this time, a vibration icon 72 is displayed on the mobile phone. When a new incoming call is received by the mobile phone (fig. 8b shows the text "new incoming call", an icon for receiving a call, and an icon for hanging up a call as examples), an event built in the mobile phone for triggering the rotor motor 30 to vibrate wakes up (fig. 8b does not show).

Accordingly, based on the descriptions of S101-S104, the mobile phone can drive the rotator motor 30 to vibrate rapidly based on audio 1 in response to the trigger event, so as to remind the user of a new incoming call through vibration effect 1. If the user has received a new incoming call or has typed an operation for stopping the rotator motor 30 from vibrating within 50ms from the start of the vibration of the rotator motor 30, the mobile phone drives the rotator motor 30 to rapidly stop the vibration based on the audio 6. On the contrary, after the rotator motor 30 vibrates for 50ms, the mobile phone continues to drive the rotator motor to vibrate rapidly based on the audio 1 until the user receives a new incoming call or enters an operation for stopping the rotator motor 30 from vibrating, and the mobile phone drives the rotator motor 30 to stop vibrating rapidly based on the audio 6.

In conclusion, the user can know that the mobile phone has a new call through the vibration effect 1, so that the user can be reminded conveniently.

It should be noted that the above embodiments can be applied to various usage scenarios in which the electronic device 1 needs to vibrate. The above embodiment is only one possible implementation manner, and the present application is not limited to the above implementation manner.

The method for controlling the vibration of the electronic equipment is applied to the electronic equipment, and the processor sends a first audio signal to the audio coding and decoding module when receiving a first trigger command, wherein the first trigger command is used for indicating the rotor motor to vibrate. Because the minimum value of the effective amplitude of the first audio signal is greater than the effective amplitude of the reference signal, the audio coding and decoding module can obtain the first PWM signal with the duty ratio close to 100% or equal to 100% by comparing the first audio signal with the reference signal, namely the waveform of the first PWM signal is a direct current voltage waveform, and then the first PWM signal is amplified, filtered and the like, so that the direct current first driving voltage can be obtained, and the direct current first driving voltage is provided for the rotor motor, so that the rotor motor can be driven to vibrate. The processor may send a second audio signal to the audio codec module when receiving a second trigger command, where the second trigger command is used to instruct the rotator motor to stop vibrating. The effective amplitude of the second audio signal is greater than that of the reference signal, so that the audio coding and decoding module can obtain a second PWM signal with a duty ratio close to 100% or equal to 100% by comparing the second audio signal with the reference signal, and then amplify, filter and the like the second PWM signal, namely the waveform of the second PWM signal is a DC voltage waveform, a DC second driving voltage can be obtained, the phase of the second driving voltage is opposite to that of the first driving voltage, and the DC second driving voltage is provided for the rotor motor, so that the rotor motor can be driven to stop vibrating. Therefore, the effect of quick vibration and quick stop vibration of the rotor motor is realized, the vibration starting time and the vibration stopping time of the rotor motor are shortened, the service life of the rotor motor cannot be influenced by the supply of direct current, the effect of protecting the rotor motor is achieved, and the use of the rotor motor is facilitated to be prolonged. And the waveform of the first PWM signal is consistent with that of the first audio signal, so that different vibration effects of the rotor motor are controlled through different settings of the first audio signal, the requirements of different use scenes of the electronic equipment are met, and abundant special-effect vibration experience is brought to a user.

On the basis of the above embodiments, in other embodiments, the first audio signal may include at least one sub-signal. In the following, the specific content of the first audio signal is exemplified in connection with two possible representations.

In a possible representation, the first audio signal may comprise the first sub-signal, i.e. the effective amplitude of the first sub-signal is constant and the effective amplitude of the first sub-signal is larger than the effective amplitude of the reference signal. In this application, the waveform or period of the first sub-signal is not limited.

Since the effective amplitude of the first sub-signal is larger than the effective amplitude of the reference signal. Therefore, based on the description in S102, the audio codec module 20 may generate the first driving voltage of the direct current based on the first sub-signal and the reference signal. Therefore, the audio codec module 20 may provide the first driving voltage of the direct current to the rotor motor 30, and the first driving voltage rapidly increases the rotation speed of the rotor motor 30, so as to drive the rotor motor 30 to start vibrating, thereby realizing rapid vibration starting of the rotor motor 30, and avoiding poor experience brought to the user due to vibration dragging.

In order to further accelerate the rapid vibration and the rapid stop vibration of the rotor motor 30, in the present application, the effective amplitudes of the first sub-signal and the second audio signal are the same, so that the amplitude of the first driving voltage and the amplitude of the second driving voltage generated by the audio codec module 20 are equal to each other and are both greater than the amplitude of the rated voltage of the rotor motor 30. By doing so, the rapid vibration and the rapid stop of the vibration of the rotor motor 30 are remarkably accelerated, and the vibration dragging is prevented from bringing a bad experience to the user.

It should be noted that the phase of the first sub-signal and the phase of the second audio signal may be in-phase or in anti-phase. When the phase of the first sub-signal is in phase with the phase of the second audio signal, the phase of the first driving voltage or the phase of the second driving voltage is changed by the switch bridge 215 in the audio codec module 20 to ensure that the phase of the first driving voltage and the phase of the second driving voltage are in anti-phase. When the phase of the first sub-signal and the phase of the second audio signal are inverted, the phase of the first driving voltage and the phase of the second driving voltage are simultaneously changed or not changed through the switch bridge 215 in the audio codec module 20 to ensure that the phase of the first driving voltage and the phase of the second driving voltage are inverted.

For convenience of description, referring to fig. 9a, taking the oscillation starting voltage of the rotor motor 30 as 1V and the rated voltage of the rotor motor 30 as 3V as an example, when the processor 10 transmits the first sub-signal and the second audio signal to the audio codec module 20, respectively, a specific case of the driving voltage of the direct current is exemplified. For convenience of explanation, in fig. 9a, the abscissa represents time and the ordinate represents voltage. The duration corresponding to the first sub-signal is illustrated by taking the number 1 as an example, and the duration corresponding to the second audio signal is illustrated by taking the number 2 as an example.

As shown in fig. 9a, when the rotor motor 30 does not vibrate, the magnitude of the driving voltage is 0V. The audio codec module 20 may generate a first driving voltage of 5V based on the first sub-signal and the reference signal, and the rotor motor 30 vibrates rapidly since the first driving voltage 5V is greater than a rated voltage 3V of the rotor motor 30. After the duration corresponding to the first sub-signal, the audio codec module 20 may generate a second driving voltage of-5V based on the second audio signal and the reference signal, and since the absolute value of the amplitude of the second driving voltage is greater than the amplitude of the rated voltage of the rotor motor 30 by 3V and the phases are opposite, the rotor motor 30 may stop vibrating quickly.

It should be noted that, since the audio codec module 20 needs to implement the fast vibration of the rotator motor 30 based on the first sub-signal, the effective amplitude of the first sub-signal is generally large, so that the rotator motor 30 vibrates fast. In order to prolong the service life of the rotor motor 30, the present application may shorten a time duration corresponding to the first sub-signal, so as to apply the first audio signal containing the first sub-signal to a usage scenario requiring a short-time vibration of the rotor motor 30, so as to protect the rotor motor 30.

The vibration duration in the usage scenario of the rotor motor 30 vibrating for a short time here may be set according to the software and hardware conditions of the electronic device 1 and the actual usage situation of the user, and may be set to be generally equal to or less than 100 ms. The corresponding use scene may be a scene in which the mobile phone receives a new message (a short message, a multimedia message, an instant messaging message, or the like), a scene in which the rotor motor 30 vibrates when the user touches a main page key of the mobile phone, a scene in which the rotor motor vibrates when the user types in the mobile phone, or a scene in which the rotor motor vibrates when an arrow is shot in a game, which is not limited in the present application.

In another possible representation, the first audio signal comprises a plurality of sub-signals. The processor 10 may transmit each sub-signal to the audio codec module 20 one by one, or may transmit each sub-signal to the audio codec module 20 together, which is not limited in this application. In addition, the present application does not limit the storage mode, waveform, or period of each sub-signal. For example, the respective sub-signals may be stored separately to facilitate formation of different first audio signals, or may be stored together to facilitate easy calling to improve operation efficiency.

In addition, the number of the sub-signals is not limited in the application. Taking two sub-signals as an example, the first audio signal may comprise a second sub-signal and a third sub-signal which are consecutively connected.

Because the effective amplitude of the second sub-signal is greater than the effective amplitude of the reference signal, the effective amplitude of the third sub-signal is greater than the effective amplitude of the reference signal, and the second sub-signal and the third sub-signal are continuously connected, based on the description in S102, when the vibration duration of the rotor motor 30 is less than or equal to the duration of the second sub-signal, the audio codec module 20 may generate a direct-current first driving voltage based on the second sub-signal and the reference signal, and the first driving voltage rapidly increases the rotation speed of the rotor motor 30, so as to drive the rotor motor 30 to start vibrating, thereby implementing rapid vibration initiation of the rotor motor 30, and avoiding vibration dragging to bring bad experience to users.

After a period of time, when the vibration duration of the rotor motor 30 is greater than the duration of the second sub-signal, the audio codec module 20 may continuously generate the dc first driving voltage based on the third sub-signal and the reference signal, and the first driving voltage may enable the rotor motor 30 to continuously keep vibrating. That is, when the vibration time period of the rotor motor 30 is less than or equal to the sum of the time periods of the second sub-signal and the third sub-signal, the audio codec module 20 may drive the rotor motor 30 to vibrate based on the third sub-signal. When the vibration duration of the rotor motor 30 is greater than the sum of the durations of the second sub-signal and the third sub-signal, since the audio codec module 20 does not receive the new sub-signal and the audio codec module 20 has received the third sub-signal from the processor 10, the audio codec module 20 may continue to drive the rotor motor to vibrate based on the third sub-signal until the processor 10 sends the new sub-signal to the audio codec module 20.

Wherein the vibration period of the rotor motor 30 is set to a period from the reception of the first audio signal from the processor 10 to the reception of the second audio signal by the processor 10.

It should be noted that, when the vibration duration of the rotor motor 30 is greater than the sum of the durations of the second sub-signal and the third sub-signal, since the audio codec module 20 does not receive the new sub-signal and the audio codec module 20 has received the second sub-signal from the processor 10, the audio codec module 20 may continue to drive the rotor motor to vibrate based on the third sub-signal until the processor 10 sends the new sub-signal to the audio codec module 20.

The amplitude of the second sub-signal and the amplitude and phase of the third sub-signal are not limited in the present application. In some embodiments, the effective amplitude of the second sub-signal may be greater than the effective amplitude of the third sub-signal, so that the amplitude of the first driving voltage generated by the audio codec module 20 based on the second sub-signal is greater than the amplitude of the first driving voltage generated based on the third sub-signal, which not only enables the rotor motor 30 to vibrate rapidly at high voltage, but also enables the rotor motor 30 to vibrate for a long time at low voltage, thereby being beneficial to meeting the use scenario of the rotor motor 30 vibrating for a long time, saving the driving consumption of the rotor motor 30, and meeting the use requirement of the electronic device 1 that the rotor motor 30 needs to vibrate for a long time.

The vibration duration in the usage scenario of the rotor motor 30 vibrating for a long time here can be set according to the software and hardware conditions of the electronic device 1 and the actual usage situation of the user, and can be set to be greater than 100ms in general. The corresponding use scene may be a scene in which the mobile phone receives a new incoming call, a scene in which an alarm is prompted or a memo is prompted, or a scene in which the rotor motor vibrates while the user types the mobile phone, which is not limited in the present application.

In addition, the low voltage here may be understood as that when the effective amplitude of the second sub-signal may be greater than that of the third sub-signal, the driving voltage obtained based on the third sub-signal may become smaller than the driving voltage obtained based on the second sub-signal. That is, the driving voltage obtained based on the second sub-signal is high voltage, and the driving voltage obtained based on the third sub-signal is low voltage. The magnitude of the low voltage and the high voltage may be set based on the starting voltage and the rated voltage of the rotor motor 30. For example, when the starting voltage of the rotor motor 30 is 1V and the rated voltage of the rotor motor 30 is 3V, the amplitude of the high voltage may be greater than 3V, and the amplitude of the low voltage may be greater than or equal to 1V and less than or equal to 3V. It should be noted that the example is only illustrative.

In order to further accelerate the rapid vibration and the rapid stop vibration of the rotor motor 30, in the present application, the effective amplitudes of the second sub-signal and the second audio signal are the same, so that the amplitudes of the first driving voltage and the second driving voltage generated by the audio codec module 20 are equal to each other and are both greater than the amplitude of the rated voltage of the rotor motor 30. By doing so, the rapid vibration and the rapid stop of the vibration of the rotor motor 30 are remarkably accelerated, and the vibration dragging is prevented from bringing a bad experience to the user.

It should be noted that the phase of the second sub-signal and the phase of the second audio signal may be in-phase or in anti-phase. When the phase of the second sub-signal is in phase with the phase of the second audio signal, the phase of the first driving voltage or the phase of the second driving voltage is changed by the switch bridge 215 in the audio codec module 20 to ensure that the phase of the first driving voltage and the phase of the second driving voltage are in opposite phase. When the phase of the second sub-signal is opposite to the phase of the second audio signal, the phase of the first driving voltage and the phase of the second driving voltage are simultaneously changed or not changed by the switching bridge 215 in the audio codec module 20 to ensure that the phase of the first driving voltage and the phase of the second driving voltage are opposite.

For convenience of description, referring to fig. 9b, taking the oscillation starting voltage of the rotor motor 30 as 1V and the rated voltage of the rotor motor 30 as 3V as an example, when the processor 10 transmits the first audio signal and the second audio signal to the audio codec module 20 respectively, where the first audio signal includes the second sub-signal and the third sub-signal that are connected in series, a specific case of the driving voltage of the direct current is exemplified. For convenience of explanation, in fig. 9b, the abscissa represents time and the ordinate represents voltage. The duration corresponding to the second sub-signal is illustrated by taking the number 1 as an example, the duration corresponding to the third sub-signal is illustrated by taking the number 2 as an example, and the duration corresponding to the second audio signal is illustrated by taking the number 3 as an example.

As shown in fig. 9b, when the rotor motor 30 does not vibrate, the magnitude of the driving voltage is 0V. The audio codec module 20 may generate a first driving voltage of 5V based on the second sub-signal and the reference signal, and the rotor motor 30 vibrates rapidly since the first driving voltage 5V is greater than a rated voltage 3V of the rotor motor 30. In order to save driving power consumption, the audio codec module 20 may generate a first driving voltage of 3V based on the third sub-signal and the reference signal, through a time period corresponding to the second sub-signal, the first driving voltage 3V causing the rotator motor 30 to continue to keep vibrating. After the duration corresponding to the third sub-signal, the audio codec module 20 may generate a second driving voltage of-5V based on the second audio signal and the reference signal, and the rotor motor 30 may stop vibrating quickly because the absolute value of the amplitude of the second driving voltage is greater than the amplitude of the rated voltage of the rotor motor 30 and the phases of the second driving voltage are opposite.

In addition, because the audio signal is very editable, the effective amplitude (or gain) of each sub-signal in the first audio signal can be set differently, so that the special-effect vibration of the rotor motor 30 can be realized, the vibration effect of the electronic device 1 can be enriched, and the vibration requirements of different use scenes can be met.

For example, the electronic device 1 is a mobile phone, and in the mobile phone, each sub-signal in the first audio signal may include: audio 1, audio 2, audio 3, audio 4, audio 5, and audio 6.

The effective amplitudes of audio 1, audio 2 and audio 3 are equal, and the respective corresponding durations of audio 1, audio 2 and audio 3 are different. The effective amplitudes of the audio 4 and the audio 5 are different from those of the audio 1, the audio 2 and the audio 3 respectively, and the corresponding time durations of the audio 4 and the audio 5 are the same. And the phases of tone 1, tone 2, tone 3, tone 4, and tone 5 are in phase, the gerotor motor 30 can be independently driven to start oscillation. Tone 6 is opposite in phase to tone 1, tone 2, tone 3, tone 4, and tone 5, and tone 6 is able to independently drive the gerotor motor 30 to stop vibrating.

In order to realize the vibration requirements of different scenes, the processor 10 in the mobile phone may continue the audio 6 to at least one of the audio 1, the audio 2, the audio 3, the audio 4, and the audio 5, and after the comparison, amplification, filtering, and the like of the audio codec module 20, different direct current driving voltages may be provided to the rotator motor 30, so as to realize different vibration effects of the rotator motor 30.

For convenience of description, referring to fig. 9c, taking the oscillation starting voltage of the rotator motor 30 as 1V and the rated voltage of the rotator motor 30 as 3V as an example, when the processor 10 transmits a first audio signal and a second audio signal to the audio codec module 20, respectively, where the first audio signal includes audio 4, audio 1, audio 2, audio 5, and audio 3 that are connected in series, and the second audio signal is audio 6, a specific case of the driving voltage of the direct current is exemplified. For convenience of explanation, in fig. 9c, the abscissa represents time and the ordinate represents voltage. The duration corresponding to the audio 1 is illustrated by taking the numeral 1 as an example, the duration corresponding to the audio 2 is illustrated by taking the numeral 2 as an example, the duration corresponding to the audio 3 is illustrated by taking the numeral 3 as an example, the duration corresponding to the audio 4 is illustrated by taking the numeral 4 as an example, the audio 5 is illustrated by taking the duration corresponding to the numeral 5 as an example, and the duration corresponding to the audio 6 is illustrated by taking the numeral 6 as an example.

As shown in fig. 9c, when the rotor motor 30 does not vibrate, the magnitude of the driving voltage is 0V. The audio codec module 20 may generate a first driving voltage of 5V based on the audio 4 and the reference signal, so that the rotor motor 30 vibrates rapidly since the first driving voltage 5V is greater than a rated voltage 3V of the rotor motor 30. In order to save driving power consumption, the audio codec module 20 may generate a first driving voltage of 3V, which is 3V such that the rotator motor 30 continues to maintain vibration, based on the audio 1 and the reference signal for a duration corresponding to the audio 4. After the duration corresponding to the audio 1, the audio codec module 20 may generate a first driving voltage of 3V based on the audio 2 and the reference signal, and the first driving voltage of 3V may make the rotator motor 30 continuously maintain the vibration. After the duration corresponding to the audio 2, the audio codec module 20 may generate a 2V first driving voltage based on the audio 5 and the reference signal, and the first driving voltage 2V may make the rotor motor 30 continuously maintain the vibration. After the duration corresponding to the audio 5, the audio codec module 20 may generate a 3V first driving voltage based on the audio 3 and the reference signal, and the first driving voltage 3V may make the rotator motor 30 continuously maintain the vibration. After the duration corresponding to the audio 3, the audio codec module 20 may generate a second driving voltage of-5V based on the audio 6 and the reference signal, where the absolute value of 5V of the amplitude of the second driving voltage is greater than the amplitude of 3V of the rated voltage of the rotor motor 30 and the phases of the second driving voltage are opposite, so that the rotor motor 30 stops vibrating quickly.

It should be noted that, in the vibration process of the rotor motor 30, the amplitude of the driving voltage may be smaller than the amplitude of the rated voltage of the rotor motor 30, and it is only required that the amplitude of the driving voltage is greater than or equal to the amplitude of the starting voltage of the rotor motor 30 so that the rotor motor 30 keeps vibrating.

In addition, in the case of the driving voltage of the rotor motor 30 shown in fig. 9a to 9c and fig. 2b, respectively, when the rotor motor 30 stops vibrating, the present application can generate a driving voltage of-5V to drive the rotor motor 30 to stop vibrating, whereas the related art 1 needs to stop vibrating by means of self-damping of the rotor motor.

In the case of the driving voltage of the rotor motor 30 shown in fig. 9a to 9c and fig. 3b, the driving voltage that can be generated by the present application can be 5V, 3V, 2V, etc. in the time period between the rapid vibration and the rapid stop vibration of the rotor motor 30, and the driving voltage is greater than the starting vibration voltage of the rotor motor 30 to maintain the vibration of the rotor motor 30, and the supply of the direct current does not affect the life of the rotor motor, thereby protecting the rotor motor. Whereas the PWM driver in the related art 2 needs a large frequency to generate a PWM signal with a duty ratio of, for example, 5V 60%, which easily causes the PWM driver to switch the voltage back and forth, resulting in an influence on the life of the rotor motor electrically connected to the PWM driver.

In the present application, the usage scenario of the electronic device 1 may be a scenario in which only vibration occurs, or a scenario in which a ringtone and vibration are combined. In a combined scenario of ring tone and vibration, on the basis of the embodiment shown in fig. 4, as shown in fig. 10, the electronic device 1 of the present application may further include: an Integrated Circuit (IC) 41 and a speaker 42, the processor 10 is further electrically connected to the IC 41, and the IC 41 is further electrically connected to the speaker 42.

The specific implementation form of the peripheral IC 41 is not limited in the present application, and it is only necessary that the peripheral IC 41 can control the speaker 41 to play the ring tone or stop playing the ring tone. And the number or type of the speakers 42 is not limited in this application. It should be noted that, in the present application, the function of playing the ring tone by the speaker 42 may be implemented by using the audio codec module instead of controlling the speaker 42 by the peripheral IC 41, which is not limited in the present application.

In the present application, the processor 10 may drive the rotator motor 30 to start vibrating while controlling the speaker 42 to play a bell sound through the peripheral IC 41, so that the rotator motor 30 may vibrate as the bell sound of the speaker 42 is played. And the processor may drive the rotator motor 30 to stop vibrating while controlling the speaker 42 to stop playing the bell sound through the peripheral IC 41, so that the rotator motor 30 may stop vibrating as the bell sound of the speaker 42 stops playing. Thereby, the effect of ringing the electronic device 1 is achieved.

The present application does not limit the parameters such as the type or number of the ring tones. The ring tone may be stored in the electronic device 1 in advance, may also be stored in the electronic device 1 by the user, and may also be stored by combining the foregoing two manners, which is not limited in this application. And generally, the audio signal corresponding to the ring tone is usually different from the first audio signal. Of course, the audio signal corresponding to the ring tone may also be the same as the first audio signal. The audio signal corresponding to the ring tone may be obtained based on at least one parameter of a beat, a drum point, or a beat of the ring tone.

It should be noted that the processor 10 does not control the speaker 42 and the rotor motor 30 sequentially, and the setting is specifically performed according to the actual requirement, the delay time period of the speaker 42, and the delay time period of the rotor motor 30. For example, to ensure the consistency of the ring tone playing and the vibration effect, the processor may drive the rotator motor 30 to start vibrating, and control the speaker 42 to play the ring tone after the delay time of the rotator motor 30.

Based on the foregoing description, since the rotator motor 30 can realize different vibration effects, in the present application, each ring tone can be associated with one or more vibration effects, and the first audio signal corresponding to each vibration effect is different, so as to select a personalized vibration effect for the user, thereby improving the user experience.

The vibration effect associated with each ringtone may be set when the electronic device 1 leaves a factory, or may not be set when the electronic device 1 leaves a factory and may be changed or newly created by a user, which is not limited in the present application. In addition, the vibration effects associated with the respective ringtones may be the same or different, which is not limited in this application.

Next, referring to fig. 11a, taking the electronic device 1 as a mobile phone as an example, a specific implementation process of the electronic device 1 for ringing with ringing is illustrated. For convenience of explanation, fig. 11a illustrates that the audio signal corresponding to the ringtone 1 is different from the first audio signal.

As shown in fig. 11a, it is assumed that ring 1 has 4 vibration effects associated with each other, and the text "ring 1+ no vibration", the text "ring 1+ vibration effect 1", the text "ring 1+ vibration effect 2", the text "ring 1+ vibration effect 3", and the text "ring 1+ vibration effect 4" are displayed on the display screen of the mobile phone.

Wherein the no-vibration effect does not correspond to the first audio signal. The first audio signals corresponding to the 4 vibration effects are audio 1, audio 2, audio 3 and audio 4 on the display screen of the mobile phone. Taking the starting vibration voltage of the rotor motor 30 as 1V and the rated voltage of the rotor motor 30 as 3V as an example, the icon of the character "vibration effect 1" corresponds to the vibration effect generated by the audio 1, and the vibration effect corresponding to the audio 1 is: the vibration was carried out for 30ms at a driving voltage of 5V and for 20ms at a driving voltage of 3V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon for the word "vibration effect 2" corresponds to the vibration effect produced by audio 2 and audio 5, with audio 2 corresponding to the vibration effect: vibrate for 30ms at a driving voltage of 5V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon for the word "vibration effect 3" corresponds to the vibration effect produced by audio 3 and audio 5, with audio 3 corresponding to the vibration effect: the vibration was carried out for 20ms at a driving voltage of 5V and for 30ms at a driving voltage of 2V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon for the word "vibration effect 4" corresponds to the vibration effect produced by audio 4 and audio 5, with audio 4 corresponding to the vibration effect: the vibration was carried out for 20ms at a driving voltage of 5V, for 30ms at a driving voltage of 2V, and for 10ms at a driving voltage of 4V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. A new incoming call in the phone has ring 1 set up and no vibration effect (illustrated in fig. 11a by showing ring icon 101 and stop vibration icon 102 as an example). If the user wants to set that the mobile phone has the vibration effect while playing the ring 1, the user may enter an operation for changing the vibration effect 1 associated with the ring 1 on the mobile phone, for example, click a position corresponding to the text "ring 1+ vibration effect 1" on the mobile phone (in fig. 11a, an opposite hook icon is displayed at a position corresponding to the text "ring 1+ vibration effect 1" after the dotted line circle is clicked, and the opposite hook icon at a position corresponding to the text "ring 1+ no vibration" disappears as an example), so that the ring 1 is associated with the vibration effect 1 corresponding to the audio 1.

Thus, when a new incoming call comes from the mobile phone (fig. 11a shows the text "new incoming call", the icon for answering the call, and the icon for hanging up the call), the mobile phone can vibrate with the vibration effect 1 corresponding to the audio 1 while playing the ring 1 (fig. 11a shows the ring icon 101 and the vibration icon 103 as an example).

Based on the foregoing description, since the rotor motor 30 can achieve different vibration effects, in the present application, the electronic device 1 may set different audio signals corresponding to different ringtones, and each audio signal corresponds to a different vibration effect, so that the rotor motor 30 is driven to vibrate by the audio signal corresponding to each ringtone, so as to select an individualized vibration effect for a user, and improve the user experience of the user.

Next, referring to fig. 11b, taking the electronic device 1 as a mobile phone as an example, a specific implementation process of the electronic device 1 for ringing with ringing is illustrated. For convenience of explanation, fig. 11b illustrates an example in which the audio signal corresponding to the ringtone 1 is the same as the first audio signal.

As shown in fig. 11b, assume that the mobile phone stores ring 1, ring 2, ring 3, and ring 4. Ring 1, ring 2, ring 3 and ring 4 correspond to different vibration effects, respectively. Taking the starting vibration voltage of the rotor motor 30 as 1V and the rated voltage of the rotor motor 30 as 3V as an example, the icon of the text "vibration effect 1" corresponds to the vibration effects generated by the audio 1 and the audio 5 corresponding to the ring 1, and the vibration effect corresponding to the audio 1 is: the vibration was carried out for 30ms at a driving voltage of 5V and for 20ms at a driving voltage of 3V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon of the word "vibration effect 2" corresponds to the vibration effect produced by audio 2 and audio 5 corresponding to ring tone 2, and the vibration effect corresponding to audio 2 is: vibrate for 30ms at a driving voltage of 5V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon of the word "vibration effect 3" corresponds to the vibration effect produced by the audio 3 and the audio 5 corresponding to the ring tone 3, and the vibration effect corresponding to the audio 3 is: the vibration was carried out for 20ms at a driving voltage of 5V and for 30ms at a driving voltage of 2V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V. The icon of the word "vibration effect 4" corresponds to the vibration effects generated by the audio 4 and the audio 5 corresponding to the ring tone 4, and the vibration effect corresponding to the audio 4 is: the vibration was carried out for 20ms at a driving voltage of 5V, for 30ms at a driving voltage of 2V, and for 10ms at a driving voltage of 4V. The vibration effect corresponding to audio 5 is: the vibration was stopped at a driving voltage of-5V.

The phone is in silent mode and has no vibration effect (fig. 11b illustrates the stop ring icon 104 and stop vibration icon 102 as examples). If the user wants to set the mobile phone to have a vibration effect along with the playing of the ring tone 1, the user may enter an operation for changing the mobile phone mode on the mobile phone, such as clicking a position corresponding to the ring tone 1 on the mobile phone (in fig. 11b, it is illustrated that an opposite hook icon showing an opposite hook icon and a position corresponding to no text disappears after the dotted line circle is clicked) and clicking a position corresponding to the right side of the vibration button 105 located in the upper right corner of the mobile phone (in fig. 11b, it is illustrated that the vibration button 105 is changed from an off state located on the left side of the vibration button 105 to an on state located on the right side of the vibration button 105), so that the ring tone 1 is associated with the vibration effect generated by the audio signal corresponding to the ring tone 1.

Thus, when a new incoming call comes from the mobile phone (fig. 11b shows the text "new incoming call", the icon for answering the call, and the icon for hanging up the call), the mobile phone can vibrate with the vibration effect corresponding to ring 1 while playing ring 1 (fig. 11b shows ring icon 101 and vibration icon 103 as an example). With continued reference to fig. 10, the electronic device 1 of the present application may further include: a memory 50, the processor 10 being further electrically connected to the memory 50. The memory 50 stores a first audio signal and a second audio signal, and the first audio signal or the second audio signal may be pre-stored in the memory 50 by the electronic device 1, may also be stored in the memory 50 by a user, or may also be a combination of the foregoing two ways, which is not limited in this application. In addition, the memory 50 may also store audio signals corresponding to ring tones, and the like.

The present application does not limit the parameters such as the number and the type of the memory 50. For example, a Double Data Rate SDRAM (DDR SDRAM), a Flash Memory (UFS), or a Static Random Access Memory (SRAM) in a processor, etc. are used.

Based on the foregoing, in one possible implementation manner of S101, the processor 10 may call the first audio signal from the memory 50 based on the electrical connection relationship between the memory 50 and the processor 10 when receiving the first trigger command. Thus, the processor 10 may transmit the first audio signal to the audio codec module 20.

In an alternative implementation manner of S103, when receiving the second trigger command, the processor 10 may call the second audio signal from the memory 50 based on the electrical connection relationship between the memory 50 and the processor 10. Accordingly, the processor 10 may transmit the second audio signal to the audio codec module 20.

It should be noted that the first audio signal and the second audio signal may be stored in different locations of the same memory 50, may also be stored in the same location of the same memory 50, and may also be stored in different memories 50, which is not limited in this application.

The memory 50 may store the first audio signal including one sub-signal, may store the first audio signal including a plurality of sub-signals, or may store the first audio signal of the above two modes, which is not limited in the present application. When the electronic device 1 requires the rotor motor 30 to vibrate, the processor 10 may recall the first audio signal corresponding to a specific usage scenario from the memory 50, so that the rotor motor 30 may have different vibration effects with different first audio signals.
