Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present application provides a control method, including:

obtaining a vibration instruction;

controlling a resonant component of the electronic equipment to be in a protection mode based on the vibration instruction;

controlling a vibration motor of the electronic equipment to respond to the vibration instruction based on the vibration instruction;

and when the resonant assembly is in the protection mode, the vibration influence on the resonant assembly generated by the vibration motor in the process of responding to the vibration instruction can be at least reduced.

For example, taking an electronic device as a mobile terminal as an example, the electronic device may be a mobile phone, and may also be a device with a vibration response function, such as a notebook computer and a tablet computer. When a user uses the mobile phone to perform touch operation, or the user receives notification information and an incoming call, the mobile phone generates a vibration instruction, such as vibration event information, to be sent to a vibration motor inside the mobile phone so as to control the vibration motor to generate vibration and further drive the mobile phone to generate vibration integrally in order to improve the touch experience of the user, or to notify the user to check information and answer a call. In the mobile phone system of the mobile phone in this embodiment, after the control devices including the chip and the processor inside the mobile phone obtain the vibration instruction, the resonance component in the electronic device is controlled to be in the protection mode based on the vibration instruction. The resonant assembly is not particularly limited and may be any two or more devices associated with each other in the apparatus to be capable of resonating together under the action of the vibration motor. The specific content of the protection mode in this embodiment is not certain, that is, in this embodiment, the electronic device may have a plurality of different protection modes, and when the resonance component is controlled to be in the protection mode based on the vibration instruction, which protection mode the resonance component should be in may be determined according to the specific vibration content of the vibration instruction, such as information of the vibration type, the vibration frequency, the vibration amplitude, and the like. Moreover, when the resonant assemblies are in multiple groups, the protection modes of each group of resonant assemblies can be the same or different, and the resonant assemblies which are possibly resonated can be controlled to be in the protection mode according to the content of the vibration instruction, while the other resonant assemblies are not in the protection mode. When the system determines that the resonant assembly is in the protection mode, the vibration motor is controlled to generate vibration based on the vibration instruction, or the vibration motor can be controlled to generate vibration while the resonant assembly is controlled to be in the protection mode. So can make the resonance subassembly be in when the protection mode, or when being converted into under the protection mode promptly, the vibration motor just begins to vibrate for the resonance subassembly can reduce the vibration influence that the vibration motor produced the resonance subassembly at the in-process of responding to the vibration instruction at least under the protection mode, avoids the resonance subassembly to produce the noise because of resonance each other or with surrounding device, realizes the noise reduction effect.

In addition, the control method in the embodiment does not relate to the change of a hardware structure in the electronic equipment, and only relates to the improvement of a software layer, so that the cost is not increased, and the type selection of the vibration motor and other driving type devices, such as a focusing motor, can be decoupled, and the dependence on the type selection of the devices is avoided.

Specifically, the resonant assembly in this embodiment is a camera module, and includes a lens, a lens barrel, a focusing motor, and the like, where the lens is disposed in the lens barrel, and the focusing motor is connected to the lens for driving the lens to move in the lens barrel, and when an image is taken, the focusing motor drives the lens to move for focusing, and the like. Of course, the focus motor may be replaced by other driving devices as long as the driving of the lens can be completed under the system control. For example, the lens barrel may be provided with an electromagnetic slide rail and an electromagnetic block, which can generate magnetic forces in different directions and strengths under different currents, to push the pulley and drive the lens to move. In the present embodiment, only the focus motor is exemplarily described as a driving device (the same applies below). Furthermore, because the lens is required to move smoothly in the lens barrel, a certain gap is usually reserved between the lens and the inner wall of the lens barrel, and just because of the gap, when the vibration motor vibrates, the vibration force can be transmitted to the focusing motor, the lens and the lens barrel based on mechanical conduction, so that the lens is driven to collide with the lens barrel, and then noise is generated, so that certain abrasion or potential safety hazard can be generated on the lens, the service life of the lens is influenced, and the use experience of a user on the electronic equipment can be reduced.

In order to reduce and avoid collision between the lens and the lens barrel, when the resonance component of the control electronic device is in the protection mode in this embodiment, the method includes:

and controlling the lens of the camera module to move to a target position based on a target driving force, wherein the target driving force is larger than a vibration force generated in the process of responding to the vibration instruction by the vibration motor.

Alternatively, the system can control the focusing motor to generate a target driving force based on the vibration instruction, so that the focusing motor drives the lens in the camera module to move to a target position based on the target driving force, and the lens does not collide with the lens barrel at the target position, thereby reducing and eliminating the noise. The specific value of the target driving force is not certain, but needs to be larger than the vibration force generated in the process of responding to the vibration command by the vibration motor, i.e. the vibration force generated in the process of generating vibration by the vibration motor, so that at least the focusing motor can stably and quickly drive the lens to the target position based on the target driving force, and the lens cannot collide with the lens barrel before, during, or even after the vibration of the vibration motor.

Because the outer fringe of camera lens all has certain clearance with the inner wall of lens cone between, and the vibration mode of vibrating motor, including the vibration direction all not unique, so for the vibration of reply vibrating motor in different vibration directions, the system has adopted the following different control mode control camera lens to remove:

the first embodiment is as follows:

controlling the lens of the camera module to move to the target position based on the target driving force, including:

and if the vibration instruction is used for instructing the electronic equipment to generate vibration feedback of the first dimension, controlling the lens of the camera module to move to the bottom of the lens barrel or the top of the lens barrel based on the target driving force.

In this embodiment, if it is known based on the vibration instruction that the electronic device needs to generate vibration feedback in a first dimension, for example, the first dimension is a dimension corresponding to the x and y axes in the coordinate system, namely, the vibration direction of the electronic equipment is positioned in the plane of the x axis and the y axis, and the displacement generated by the vibration is also a parallel plane which is positioned in the plane relative to the XY axis, because the camera module is arranged in the electronic equipment (such as a mobile phone, a tablet computer and the like), therefore, the main optical axis of the lens of the camera module is vertical to the XY plane, when the vibration motor of the electronic equipment responds to the vibration instruction and generates vibration direction in the plane of the x and y axes, the lens of the lens group of the camera is suspended in the lens barrel, so that the lens can also resonate in the vibration direction (the vibration direction of the plane where the XY axes are located) and touch the inner wall of the lens barrel of the lens group to generate noise. Therefore, the direction of the target driving force in this embodiment is perpendicular to the plane of the XY axes, and the focusing motor in the camera module drives the lens to move to the top of the lens barrel or the bottom of the lens barrel based on the target driving force, so that the lens and the top or the bottom of the lens barrel are attached together, the contact surface area is increased, and further the frictional resistance is increased, so that the lens barrel and the lens can form a whole. When the vibration motor vibrates, the lens barrel and the lens do not move relatively but move together as a whole, so that the lens does not collide with the lens barrel to generate noise.

Example two:

controlling the lens of the camera module to move to the target position based on the target driving force includes:

if the vibration instruction is used for instructing the electronic equipment to generate vibration feedback of the first dimension, controlling the lens of the camera module to move to the bottom of the lens barrel or the top of the lens barrel based on the first driving force, and lifting the driving force to the target driving force when the lens moves to the bottom of the lens barrel or the top of the lens barrel.

In this embodiment, when the system determines that the vibration command requires the electronic device to generate vibration feedback in the first dimension, for example, the first dimension is also a dimension corresponding to the x and y axes in the coordinate system, that is, the vibration direction of the electronic device is located in a plane surrounded by the x and y axes. The direction of the target driving force in this embodiment is perpendicular to the plane of the XY axes, and the lens is driven by the focusing motor in the camera module to move to the top of the lens barrel or the bottom of the lens barrel based on the target driving force, so that the lens is attached to the top or the bottom of the lens barrel. When the system determines that the lens moves to the end part of the lens barrel, a target driving force is determined (namely, the target driving force is greater than the force for moving the lens to the end part of the lens barrel), the driving force of the focusing motor is adjusted based on the target driving force, the force value is increased to the force value of the target driving force, the focusing motor is controlled to apply pushing force to the lens based on the adjusted force value, the lens is tightly attached to the end part of the lens barrel, the contact friction force between the lens and the inner end face of the lens barrel is further increased, the lens and the lens barrel can be effectively ensured to be more stably and firmly integrated, and the relative motion, collision and noise generation cannot be caused under the influence of the vibration motor.

Further, with the two embodiments described above, when the system controls the lens of the camera module to move to the target position based on the target driving force, as shown in fig. 2, the method further includes:

determining the equipment posture of the current electronic equipment;

the target position is determined to be the bottom of the lens barrel or the top of the lens barrel based on the device pose.

That is, before controlling to drive the lens, a current device posture of the electronic device needs to be determined, for example, whether the electronic device is in a horizontal state or a handheld state at present, whether a camera module of the electronic device faces a desktop or deviates from the desktop, and the like.

Specifically, the electronic device may be provided with a gravity sensor, a level and other devices for assisting in determining the posture of the device, the system may obtain current gravity information of the electronic device through such devices, the gravity information includes gravity component information of the electronic device in each direction, and the system may calculate the device posture of the current electronic device based on the gravity component information, for example, in which holding posture the device is held by a user and is matched with the device posture, the electronic device is currently placed on a desktop with its front side facing upward, or placed on a desktop with its back side facing upward, and the like. Because the installation position of the camera module on the electronic equipment is fixed, the current position of the lens in the camera module is different when the electronic equipment is in different postures, for example, the gravity components of the lens in different device postures are different, which causes the lens to displace relatively closer to the top or bottom of the lens barrel without driving the focusing motor, and furthermore, because the gravity borne by the lens is different, the driving force required for driving the lens to move towards the top or the bottom of the lens barrel is different, if the camera module is disposed on the back of the electronic device, the lens is driven to move toward the top of the lens barrel with a least effort if the electronic device is placed on the desktop with the right side facing upward. Similarly, when the electronic device is in the inclined posture, the gravity component borne by the lens is different from the gravity component borne by the electronic device when the electronic device is vertically arranged on a table top or when a user holds the device in front of the table top, and the force borne by the lens is larger than the force borne by the electronic device. When the system determines the target position, the system can comprehensively determine by combining the distance between the current lens and the top and the bottom of the lens barrel and the required driving force ratio, and under the current equipment posture, the system can drive the lens to the top of the lens barrel more time-saving and labor-saving or drive the lens to the bottom of the lens barrel more time-saving and labor-saving, and determine the final target position as the position which corresponds to the driving process more time-saving and labor-saving. For example, when the lens is just paused, it may be near or directly at the top of the barrel, then the system directly determines that the top of the barrel is the target position.

Further, in practical application, when determining the target driving force or the first driving force, the system may determine the rated driving force according to a driving force required by the electronic device to drive the lens to move in a state of being set on a desktop or being held in front of a user, or based on a self weight of the lens, a connection structure between the lens barrel and the lens, a power of the focusing motor, a length of the lens barrel, i.e., a distance that the lens needs to be driven to move, and the like, and may determine the rated driving force comprehensively based on relevant historical parameters and empirical parameters, the performance of a driving device for driving the lens to move, and the rated driving force may be a specific value or a range of values. For example, when the gravity component of the electronic device or the lens or the included angle between the electronic device or the lens and the preset reference position is within the corresponding threshold range, the lens is driven to move by the rated driving force or a driving force value corresponding to the range. If the change amplitude of the posture of the device is large, and the gravity component borne by the lens is increased, different gravity compensation components can be added to the rated driving force according to the increase of the gravity component, so that the target driving force is obtained. The gravity compensation component is not only related to the gravity component borne by the lens, but also related to the distance between the current position and the target position of the lens. When the system determines the target driving force, the value of the delivered current can be determined accordingly to control the focus motor to apply the target driving force to the lens based on the current value.

Example three:

controlling the lens of the camera module to move to the target position based on the target driving force includes:

and if the vibration instruction is used for indicating the electronic equipment to generate vibration feedback of a second dimension, controlling the lens of the camera module to move to the middle of the lens barrel based on the target driving force.

In this embodiment, if it is known based on the vibration instruction that the electronic device is required to generate vibration feedback in the second dimension, for example, the second dimension is the dimension corresponding to the z-axis in the coordinate system, namely, the vibration direction of the electronic equipment is positioned in the plane of the z axis, because the camera module is installed in the electronic equipment (such as a mobile phone, a tablet computer and the like), therefore, the main optical axis of the lens of the camera module is vertical to the XY plane, when the vibration motor of the electronic equipment responds to the vibration instruction to generate the vibration direction positioned in the plane of the Z axis, if the distance between the lens of the lens group of the camera and the top or the bottom of the lens barrel is relatively short, the lens can generate resonance in the direction of the main optical axis when the electronic equipment generates vibration in the direction of the Z axis, so that noise is generated when the lens touches the top or the bottom of the lens group which is short. Therefore, the direction of the target driving force in this embodiment is perpendicular to the plane of the XY axes, and the focusing motor in the camera module is used to drive the lens to move to the middle of the lens barrel based on the target driving force, so that the amplitude of the resonance generated by the lens located in the middle of the lens barrel is smaller than the distance from the lens located in the middle of the lens barrel to any one end of the lens barrel, that is, a sufficient vibration space is reserved for the lens in the vibration direction, thereby effectively ensuring that the lens does not collide with the end of the lens barrel, and generating noise.

Example four:

controlling the lens of the camera module to move to the target position based on the target driving force includes:

and if the vibration instruction is used for indicating the electronic equipment to alternately generate vibration feedback of the first dimension and the second dimension, controlling the lens of the camera module to move to the top of the lens barrel or the bottom of the lens barrel based on the target driving force.

In this embodiment, if it is known based on the vibration instruction that the electronic device needs to generate vibration feedback alternately in the first dimension and the second dimension, for example, the vibration feedback in the first dimension is generated in the first time period, the vibration feedback in the second dimension is generated in the second time period after the first time period, and the above operations are repeated alternately, the system determines the target driving force (the specific determination method is the same as above), and drives the lens to move to the top or the bottom of the lens barrel based on the target driving force, and may select to continuously apply the driving force to the lens (detailed below) to ensure that the lens and the lens barrel can be integrated, and no relative motion is generated, and noise is generated.

Further, as shown in fig. 3, the control method in this embodiment further includes:

continuously providing a target driving force to maintain the lens at a target position in the process that a vibration motor of the electronic equipment responds to a vibration instruction; or

The target driving force is continuously provided during the vibration motor of the electronic device responding to the vibration instruction and within the target time period after the vibration motor of the electronic device responding to the vibration instruction is completed so as to maintain the lens at the target position.

That is, during the period from the beginning of the response to the vibration command to the end of the response to the vibration command of the vibration motor of the electronic device, the system needs to control the focus motor to continuously provide the target driving force for the lens, so that the lens can be always located at the target position during the vibration of the vibration motor, i.e. the current position is always kept stable, so as to ensure that the lens does not collide with the lens barrel to generate noise. In addition, in order to avoid that the vibration mode of the electronic device is an intermittent vibration mode, for example, after the vibration mode is vibrated for a period of time, the vibration mode is stopped for several seconds, even after several minutes, the vibration mode continues to vibrate, for example, when an alarm program of the electronic device runs, or when the electronic device runs a chat program, because the receiving of each piece of information generates vibration, a time interval exists between the receiving time points of each piece of information, or when the electronic device is in a call, the call is accidentally hung up, the opposite party dials back again, and the like, the system can control the focusing motor to continue to provide the template driving force for the lens when the vibration motor completes the vibration feedback, so that the focusing motor continues to be kept at the target position within the target time period, for example, within 2s, 6s, and 15s, to avoid frequent start and stop of the focusing motor. In practical application, the system may determine whether it is necessary to continue to control and apply the target driving force within a target time period after the vibration motor has responded to the current vibration feedback according to the type of the application program currently running on the electronic device and the vibration response type/vibration mode of the electronic device, where the target time period may be a fixed time period or may be set differently according to the type of the different application program currently running and the vibration response type/mode. For example, when the application program run by the electronic device is a chat-type program, the target time period can be relatively extended, for example, 10s, 20s, and the like.

Further, the lens in the camera module in this embodiment is installed in the lens barrel through an elastic member, such as a spring, and when the lens is moved, the elastic member is compressed to generate a restoring force for driving the lens to return from the target position to the initial position. In the case where the electronic device uses the camera module in the present embodiment, the target driving force for driving the lens to move, and the first driving force need to be able to overcome the restoring force, so as to ensure that the lens can be smoothly driven to move to the target position and be kept at the target position. In addition, when the electronic device uses the camera module of this embodiment, especially in the mode that the vibration motor may be intermittently or frequently started and stopped, it is further necessary to control the driving devices such as the focus motor to continue to provide the target driving force for the lens within the target time period after the vibration motor responds to the vibration feedback, so that the lens is continuously maintained at the target position, thereby avoiding frequent resetting of the lens when the lens is pulled by the elastic member due to frequent starting and stopping of the focus motor, and making the elastic member easily drive the lens to collide with the inner wall of the lens barrel, thereby generating noise.

Further, the control method in this embodiment further includes:

and controlling to stop providing the target driving force so that the lens is restored to the initial position under the acting force provided by the elastic piece.

For example, after determining that the vibration motor stops vibrating or after a target time period after the vibration is stopped, that is, after the determined time exceeds the target time period, the driving device such as the focus motor is controlled to stop providing the target driving force based on the preset strategy, or after determining that the vibration motor stops vibrating or after the target time period after the vibration is stopped, if the vibration motor does not vibrate again or the system does not receive a vibration instruction any more, the driving device such as the focus motor is controlled to stop providing the target driving force based on the preset strategy, so that the lens is restored from the current target position to the initial position under the elastic force accumulated by the elastic member.

Specifically, when the control stops the supply of the target driving force, the control includes:

and controlling the target driving force to gradually decrease so that the lens is slowly reset under the combined action of the elastic force of the elastic piece and the target driving force.

For example, the system may control a driving device such as a focus motor to gradually reduce the target driving force in a gradual-moving mode, so that the gradually reduced target driving force can suppress the influence of the elastic force on the lens, so that the lens is not rapidly reset by the elastic force, which is likely to generate impact with the lens barrel and generate noise, but the lens is slowly reset by the combined action of the gradually reduced target driving force and the elastic force, thereby ensuring that the lens does not collide with the lens barrel during and after the resetting process and generating noise.

As shown in fig. 4, another embodiment of the present application also provides an electronic device 100, including:

a resonance assembly 1;

a vibration motor 2; and

the controller 3 is used for obtaining a vibration instruction, controlling the resonance assembly 1 to be in a protection mode based on the vibration instruction, and controlling the vibration motor 2 to respond to the vibration instruction;

wherein, under the condition that the resonant assembly 1 is in the protection mode, the vibration influence of the vibration motor 2 on the resonant assembly 1 in the process of responding to the vibration instruction can be at least reduced.

The electronic device 100 in this embodiment may be a mobile terminal such as a mobile phone, or may be a device supporting a vibration function such as a tablet computer, a notebook computer, or a learning machine. In the electronic device 100 of the embodiment, the controller 3 may first control the resonant assembly 1 to be in the protection mode after obtaining the vibration instruction, and control the vibration motor 2 to generate vibration based on the vibration instruction when the resonant assembly 1 is in the protection mode, or may also control the vibration motor 2 to generate vibration while controlling the resonant assembly 1 to be in the protection mode. Therefore, when the resonance component 1 is in the protection mode, or is being converted into the protection mode, the vibration motor 2 starts to vibrate, so that the resonance component 1 can at least reduce the vibration influence of the vibration motor 2 on the resonance component 1 in the process of responding to the vibration instruction in the protection mode, the resonance component 1 is prevented from colliding with each other or surrounding devices to generate noise due to resonance, and the noise reduction effect is realized. In addition, in the process of reducing the generation of the collision noise, the electronic device 100 in this embodiment does not involve the modification of the hardware structure in the electronic device 100, but only involves the improvement of the software level, so that the cost is not increased, and the model selection of the vibration motor 2 and other driving devices can be decoupled, thereby avoiding the dependency on the model selection of the devices.
