Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1, a mobile terminal 10 according to an embodiment of the present disclosure includes at least one speaker 11 and a processing chip 12. The processing chip 12 is in communication connection with the speaker 11, and the processing chip 12 is configured to output at least one path of first sound source signals to the speaker 11, so as to play the first sound source signals through the speaker 11; and for outputting the at least one second sound source signal to the at least one external device 20, so as to play the second sound source signal through the at least one external device 20.

Therefore, the mobile terminal 10 can play at least one path of the first sound source signal through the speaker 11, the mobile terminal 10 can also play at least one path of the second sound source signal through the external device 20, and the multiple paths of sound source signals are played through different devices, so that the sound source signals heard by the user have a certain degree of azimuth layering, and a better stereo effect is formed.

In particular, the mobile terminal 10 may include, but is not limited to, a smartphone, a tablet, and a smart wearable device. The loudspeaker 11 may be adapted to convert the electrical signal into a sound source signal and the loudspeaker 11 may be adapted to play a first sound source signal. The number of the speakers 11 may be one or more, so that the speakers 11 can play at least one first sound source signal. The speaker 11 and the processing chip 12 may be electrically connected, and the processing chip 12 may control the playing and stopping of the first sound source signal of the speaker 11. The processing chip 12 may also be used to control communications and the like for the mobile terminal 10.

The external device 20 may include an earphone, a speaker, or the like, and the external device 20 and the mobile terminal 10 may be connected in a wired manner or in a wireless manner, for example, in a bluetooth manner, a WIFI manner, or an NFC manner. After the external device 20 is connected to the mobile terminal 10, the external device 20 can be used to play the second sound source signal. The number of the external devices 20 may be one or more, and one external device 20 may play at least one second sound source signal.

Human hearing has the ability of distinguishing the sound source directions, and when a plurality of sound sources are played simultaneously, a user can perceive the position distribution condition of each sound source signal in space by hearing. In the embodiment of the present application, the mobile terminal 10 may play at least one first sound source signal through the speaker 11, and simultaneously play a plurality of second sound source signals through the external device 20. Since the distances between the speaker 11 and the external device 20 and the user's ears are different, when the user directly hears the sound source signals, the user can feel the orientation and gradation of the respective sound source signals in addition to the loudness, pitch, and timbre of the sound source signals, thereby making it possible to obtain a stereoscopic feeling.

In one example, when the external device 20 is a bluetooth headset and is connected to the mobile terminal 10, the external device 20 may play two paths of second sound source signals, and the mobile terminal 10 may include a speaker 11, and the speaker 11 may play one path of first sound source signal, so that the user can directly hear three paths of sound source signals and can also feel the direction and level of each path of sound source signal to obtain a stereoscopic effect. The above examples and specific numerical values are provided to facilitate the description of the practice of the present application and should not be construed as limiting the scope of the present application.

Referring to fig. 2-4, in some embodiments, the number of the speakers 11 is multiple, and the multiple speakers 11 are respectively disposed on different sides of the mobile terminal 10. In this way, the plurality of speakers 11 located at different sides of the mobile terminal 10 are matched with the external device 20, so that the stereo effect of the mobile terminal 10 can be greatly improved.

In particular, the mobile terminal 10 may further include an interface 13 for connecting with an external device 20, and the interface 13 may be disposed at a lower side of the mobile terminal 10. The number of speakers 11 may be one, two, three, or four, and is not limited herein. Among them, the speaker 11 may be opened at least one of the left, right, upper and lower sides of the mobile terminal 10.

When the external device 20 is connected to the mobile terminal 10 through the interface 13, when the mobile terminal 10 plays a sound source signal, the speaker 11 may play at least one path of the first sound source signal, and the external device 20 may output a plurality of paths of the second sound source signal, so that the plurality of paths of the first sound source signal and the second sound source signal are emitted from different positions, and a stereo playing effect may be achieved. In some embodiments, the external device 20 and the mobile terminal 10 may be directly connected through WIFI or bluetooth.

In one example, the mobile terminal 10 may include only one speaker 11, and the speaker 11 may be disposed at a lower side of the mobile terminal 10, with the speaker 11 being spaced apart from the interface 13, as shown in fig. 1. In this way, the mobile terminal 10 can play two second sound source signals a1 and a2 through the external device 20, and play one first sound source signal A3 through the speaker 11.

In one example, the mobile terminal 10 includes two speakers 11, wherein one speaker 11 is disposed on a lower side of the mobile terminal 10 and spaced apart from the interface 13, and the other speaker 11 is disposed on an upper side of the mobile terminal 10, as shown in fig. 2. In this manner, the mobile terminal 10 may play the two second sound source signals a1 and a2 through the external device 20 and the two first sound source signals A3 and a4 through the speaker 11.

In one example, the mobile terminal 10 includes three speakers 11, wherein one speaker 11 is disposed at a lower side of the mobile terminal 10 and spaced apart from the interface 13, one speaker 11 is disposed at an upper side of the mobile terminal 10, and the other speaker 11 is disposed at a left side of the mobile terminal 10, as shown in fig. 3. In this manner, the mobile terminal 10 may play the two second sound source signals a1 and a2 through the external device 20 and play the three first sound source signals A3, a4, and a5 through the speaker 11.

In one example, the mobile terminal 10 includes four speakers 11, wherein two speakers 11 are spaced apart on the lower side of the mobile terminal 10 and are both spaced apart from the interface 13, and the other two speakers 11 are spaced apart on the upper side of the mobile terminal 10, as shown in fig. 4. In this manner, the mobile terminal 10 may play the two second sound source signals a1 and a2 through the external device 20 and play the four first sound source signals A3, a4, a5 and a6 through the speaker 11.

The above examples and specific numerical values are provided to facilitate the description of the practice of the present application and should not be construed as limiting the scope of the present application.

In some embodiments, the processing chip 12 is used to enable the speaker 11 and the external device 20 to play the sound source signal synchronously. Therefore, the situation that the playing of the first sound source signal and the playing of the second sound source signal are asynchronous and the use experience of a user is influenced can be avoided.

It can be understood that, when the external device 20 and the mobile terminal 10 are wirelessly connected by bluetooth, the second sound source signal is transmitted from the mobile terminal 10 to the external device 20 by wireless transmission, there may be a delay in the wireless transmission process, so that the time when the first sound source signal directly output through the speaker 11 enters the human ear is earlier than the time when the second sound source signal enters the human ear, and the sound source signal is not synchronized, so that the hearing experience of the user is not good. In this way, the processing chip 12 may be utilized to process the output time of the first sound source signal and the second sound source signal, so that the two signals can be played synchronously to improve the user experience.

In some embodiments, in the case that the external device 20 is wirelessly connected to the mobile terminal 10, the processing chip 12 is configured to determine a communication time duration between the mobile terminal 10 and the external device 20, and output the first sound source signal and the second sound source signal according to the communication time duration, so that the speaker 11 and the external device 20 play the sound source signal synchronously.

In this way, the time for outputting the first sound source signal and the second sound source signal can be controlled by detecting the communication time length between the mobile terminal 10 and the external device 20, so as to ensure the synchronous playing of the sound source signals of the speaker 11 and the external device 20.

Specifically, when the external device 20 and the mobile terminal 10 are connected by a bluetooth manner, in one example, the external device 20 is a wired earphone, and the mobile terminal 10 plays a sound source signal, the mobile terminal 10 converts the generated digital audio into an analog audio, that is, a second sound source signal, and the second sound source signal can be directly transmitted to the wired earphone through a wire and then enters the ear of the user. The transmission process is simple, the transmission time is short, and delay is hard to be perceived by human ears.

When the external device 20 and the mobile terminal 10 are wirelessly connected by wifi or bluetooth, there may be a delay in the transmission process of the second sound source signal. In one example, the external device 20 is a wireless headset that is wirelessly connected to the mobile terminal 10 via bluetooth. When the mobile terminal 10 plays the sound source signal, the mobile terminal 10 transmits the generated digital audio to the wireless earphone, because the bandwidth of bluetooth transmission is limited, the digital audio needs to be compressed into a bluetooth protocol audio code and then transmitted to the wireless earphone, then the digital audio is decompressed on the wireless earphone and then converted into an analog audio, i.e. a second sound source signal, and the second sound source signal is transmitted to the ear of the user. The steps of compressing, decompressing, and converting in the above process are the communication between the mobile terminal 10 and the external device 20, and the consumed time is the communication duration. The existence of the communication time period causes a delay in the transmission of the second sound source signal to the user's ear, for example, resulting in an out-of-sync tone of the mobile terminal 10.

The first sound source signal can be directly played through the speaker 11 of the mobile terminal 10, when the wireless earphone is wirelessly connected with the mobile terminal 10 in a bluetooth manner, the second sound source signal is delayed due to the existence of communication time, so that the time for the user to hear the first sound source signal is different from the time for hearing the second sound source signal, and the user experience is reduced.

It is understood that when the external device 20 is wirelessly connected to the mobile terminal 10 by bluetooth, the communication duration between the mobile terminal 10 and the external device 20 is affected by the distance between the mobile terminal 10 and the external device 20, interference of other electronic devices, and the power of the external device 20.

Therefore, the processing chip 12 of the mobile terminal 10 may be used to determine the communication time duration between the mobile terminal 10 and the external device 20, and then adjust the output time of the first sound source signal and the second sound source signal according to the communication time duration, so as to ensure that the first sound source signal and the second sound source signal can be played synchronously. For example, the processing chip 12 determines a communication time duration between the mobile terminal 10 and the external device 20, then controls the speaker 11 to output the second sound source signal, and when the second sound source signal reaches the communication time duration, the processing chip 12 finally controls the first sound source signal output of the external device 20, so that the first sound source signal and the second sound source signal can be played simultaneously.

In some embodiments, the processing chip 12 is configured to output the first sound source signal after outputting the second sound source signal communication duration. In this way, in the case where the external device 20 is wirelessly connected to the mobile terminal 10, the synchronized playback of the first sound source signal and the second sound source signal can be realized.

Specifically, under the condition that the external device 20 is wirelessly connected to the mobile terminal 10, the processing chip 12 controls the speaker 11 to output the second sound source signal, and when the output of the second sound source signal reaches the communication duration, the processing chip 12 controls the output of the first sound source signal of the external device 20, so that the first sound source signal and the second sound source signal after the communication duration has been output can be played synchronously. In addition, the sound source signal can be played not only through the speaker 11 but also through the external device 20, so that a stereo effect of the sound source signal playing can be achieved.

In an example, the processing chip 12 determines that the communication time of the mobile terminal 10 and the external device 20 is 100ms, and after the processing chip 12 controls the external device 20 to output the second sound source signal 100ms later, the processing chip 12 controls the speaker 11 to output the first sound source signal, so that the first sound source signal and the second sound source signal can be played synchronously, thereby improving the user experience. The above examples and specific numerical values are provided to facilitate the description of the practice of the present application and should not be construed as limiting the scope of the present application.

Referring to fig. 1 to fig. 4, a playing system 100 provided in this embodiment of the application includes the mobile terminal 10 and a plurality of external devices 20, where the external devices 20 are communicatively connected to the mobile terminal 10, and the external devices 20 are used for playing a second sound source signal.

In this way, the playing system 100 can play at least one path of the first sound source signal through the speaker 11 of the mobile terminal 10, and can also output multiple paths of the second sound source signals through the external device 20, and the multiple paths of the sound source signals are played through different devices, so that the sound source signals heard by the user have a certain degree of azimuth layering, thereby forming a better stereo effect.

In some embodiments, the external device 20 may include a headset. In this manner, the mobile terminal 10 may enable playback of the second sound source signal through the earphone.

In particular, the headset may include wired and wireless headsets. The mobile terminal 10 may be equipped with an interface 13, and a wired earphone may be directly inserted into the interface 13 to connect with the mobile terminal 10 for playing a second sound source signal. When the external device 20 is a limited headset, the wireless headset can be connected to the mobile terminal 10 by bluetooth to play the second sound source signal. It is understood that headphones, in-ear headphones, semi-in-ear headphones, and the like may be included, but are not limited thereto.

Referring to fig. 5, a playing method provided in an embodiment of the present application includes:

s10: outputting at least one path of first sound source signals to a loudspeaker 11 of the mobile terminal 10 so as to play the first sound source signals through the loudspeaker 11;

s20: outputting the at least one second sound source signal to the at least one external device 20 to play the second sound source signal through the at least one external device 20.

The playing method according to the embodiment of the present application can be implemented by the mobile terminal 10 according to the embodiment of the present application. Specifically, the mobile terminal 10 includes the processing chip 12, and each of the steps S10 and S20 may be implemented by the processing chip 12, that is, the processing chip 12 may be configured to output at least one first sound source signal to the speaker 11 of the mobile terminal 10, and may be further configured to output at least one second sound source signal to the at least one external device 20, so as to play the second sound source signal through the at least one external device 20.

Therefore, the mobile terminal 10 can play at least one path of the first sound source signal through the speaker 11, the mobile terminal 10 can also play at least one path of the second sound source signal through the external device 20, and the multiple paths of sound source signals are played through different devices, so that the sound source signals heard by the user have a certain degree of azimuth layering, and a better stereo effect is formed.

In the embodiment of the present application, the mobile terminal 10 may play at least one first sound source signal through the speaker 11, and simultaneously play at least one second sound source signal through the external device 20. Since the distances between the speaker 11 and the external device 20 and the user's ears are different, when the user directly hears the sound source signals, the orientation and the level of the respective sound source signals can be perceived, so that a stereoscopic impression can be obtained.

In one example, when the external device 20 is a bluetooth headset and is connected to the mobile terminal 10, the external device 20 may play two paths of second sound source signals, and the mobile terminal 10 may include a speaker 11, and the speaker 11 may play one path of first sound source signals, so that the user can hear three paths of sound source signals and can also feel the direction and level of each of the three paths of sound source signals to obtain a stereoscopic effect.

Referring to fig. 6, in some embodiments, the playing method may further include:

s30: the speaker 11 and the external device 20 are caused to play the sound source signal synchronously.

The playing method according to the embodiment of the present application can be implemented by the mobile terminal 10 according to the embodiment of the present application. Specifically, the mobile terminal 10 includes the processing chip 12, and the step S30 can be implemented by the processing chip 12, that is, the processing chip 12 can be used to enable the speaker 11 and the external device 20 to play the sound source signal synchronously.

Therefore, the situation that the playing of the first sound source signal and the playing of the second sound source signal are asynchronous and the use experience of a user is influenced can be avoided.

Specifically, when the external device 20 and the mobile terminal 10 are wirelessly connected by bluetooth, the second sound source signal is transmitted from the mobile terminal 10 to the external device 20 by wireless transmission, and the wireless transmission process requires a certain time. The processing chip 12 can directly output the first sound source signal to the speaker 11 of the mobile terminal 10, and the transmission process is fast. The first sound source signal may be played earlier than the second sound source signal, and the non-synchronization of the sound source signals may affect the hearing experience of the user. The loudspeaker 11 and the external equipment 20 are enabled to play the sound source signals synchronously, and the use experience of a user can be improved.

Referring to fig. 7, in some embodiments, enabling the speaker 11 and the external device 20 to play the sound source signal synchronously includes:

s31: determining the communication time length between the mobile terminal 10 and the external device 20 under the condition that the external device 20 is wirelessly connected with the mobile terminal 10;

s32: the first sound source signal and the second sound source signal are output according to the communication time length so that the speaker 11 and the external device 20 play the sound source signals synchronously.

The playing method according to the embodiment of the present application can be implemented by the mobile terminal 10 according to the embodiment of the present application. Specifically, the mobile terminal 10 includes the processing chip 12, and each of the steps S31 and S32 may be implemented by the processing chip 12, that is, the processing chip 12 may be configured to determine a communication duration between the mobile terminal 10 and the external device 20 in a case where the external device 20 is wirelessly connected to the mobile terminal 10; and is further configured to output the first sound source signal and the second sound source signal according to the communication time length, so that the speaker 11 and the external device 20 play the sound source signals synchronously.

In this way, the time for outputting the first sound source signal and the second sound source signal can be controlled by detecting the communication time length between the mobile terminal 10 and the external device 20, so as to ensure the synchronous playing of the sound source signals of the speaker 11 and the external device 20.

Specifically, when the external device 20 and the mobile terminal 10 are wirelessly connected by wifi or bluetooth, there may be a delay in the transmission process of the second sound source signal. In one example, the external device 20 is a wireless headset that is wirelessly connected to the mobile terminal 10 via bluetooth. When the mobile terminal 10 plays the sound source signal, the mobile terminal 10 transmits the generated digital audio to the wireless earphone, because the bandwidth of bluetooth transmission is limited, the digital audio needs to be compressed into a bluetooth protocol audio code and then transmitted to the wireless earphone, then the digital audio is decompressed on the wireless earphone and then converted into an analog audio, i.e. a second sound source signal, and the second sound source signal is transmitted to the ear of the user.

The steps of compressing, decompressing, and converting in the above process are the communication between the mobile terminal 10 and the external device 20, and the consumed time is the communication duration. The existence of duration of communication leads to the broadcast of second sound source signal to have the delay, and first sound source signal then accessible mobile terminal 10's speaker 11 directly broadcast, carries out wireless connection through the bluetooth mode when external equipment 20 and mobile terminal 10, and second sound source signal produces the delay owing to the existence of duration of communication for the user can hear first sound source signal earlier and hear second sound source signal again, and the asynchronous of sound source signal can reduce user's use experience.

Therefore, under the condition that the external device 20 is wirelessly connected to the mobile terminal 10, the communication time duration between the mobile terminal 10 and the external device 20 can be determined, and the output time of the first sound source signal and the output time of the second sound source signal are adjusted according to the communication time duration, so that the first sound source signal output by the speaker 11 and the second sound source signal output by the external device 20 can be synchronously played. In addition, the sound source signal can be played through the speaker 11 and the external device 20 at the same time, and a stereo effect of the sound source signal playing can be also achieved.

Referring to fig. 8, in some embodiments, outputting the first sound source signal and the second sound source signal according to the communication time duration includes:

s33: and outputting the first sound source signal after outputting the communication time length of the second sound source signal.

The playing method according to the embodiment of the present application can be implemented by the mobile terminal 10 according to the embodiment of the present application. Specifically, the mobile terminal 10 includes the processing chip 12, and the step S33 can be implemented by the processing chip 12, that is, the processing chip 12 can be used to output the first sound source signal after outputting the second sound source signal communication duration.

In this way, in the case where the external device 20 is wirelessly connected to the mobile terminal 10, the synchronized playback of the first sound source signal and the second sound source signal can be realized.

Specifically, under the condition that the external device 20 is wirelessly connected to the mobile terminal 10, the processing chip 12 controls the second sound source signal output by the speaker 11, and when the second sound source signal output reaches the communication duration, the processing chip 12 controls the first sound source signal output by the external device 20, so that the first sound source signal and the second sound source signal after the communication duration has been output can be synchronized. In addition, the sound source signal can be played not only through the speaker 11 but also through the external device 20, so that a stereo effect of the sound source signal playing can be achieved.

In one example, the processing chip 12 may be utilized to determine that the communication time of the mobile terminal 10 and the external device 20 is 150ms, the processing chip 12 first controls the external device 20 to output the second sound source signal, and after the second sound source signal is output for 150ms, the processing chip 12 then controls the speaker 11 to output the first sound source signal, so that the first sound source signal and the second sound source signal can be played synchronously, thereby improving the user experience.
