Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The terminal has two play modes, namely a receiver mode and a play-out mode.

The handset mode is a mode in which a handset in the terminal is used to sound. Because the earphone is located in the terminal, an earphone sound hole leading to the outside of the terminal needs to be formed in the vibrating diaphragm of the earphone, so that sound generated by vibration of the vibrating diaphragm in the earphone is transmitted out through the earphone sound hole and captured by human ears. Generally, the loudness of the sound emitted by the receiver is small, so that the receiver mode is suitable for sound playing in privacy scenes such as telephone answering.

The play-out mode is a mode in which a speaker in the terminal is used to generate sound. Because loudspeaker are located the inside of terminal, so, need set up the loudspeaker phonation hole leading to the terminal outside in the vibrating diaphragm department of loudspeaker for the produced sound of vibrating diaphragm vibration in the loudspeaker propagates out through this loudspeaker phonation hole, thereby is caught by the people's ear. Because the loudness of the sound played by the loudspeaker is large, the play-out mode is suitable for playing the sound in non-privacy scenes such as music.

In the related art, the receiver and the speaker need to be installed in the terminal, so when the stacking layout of the terminal is performed, the positions of the receiver and the speaker need to be reserved, the design of the terminal is complex, and the installation of the receiver and the speaker in the terminal increases the production cost of the terminal. In addition, a receiver sound hole needs to be formed in the receiver, a loudspeaker sound hole needs to be formed in the loudspeaker, and the firmness of the structure of the terminal and the attractiveness of the terminal can be affected by forming the hole in the terminal.

In this embodiment, the motor that is used for the vibration originally in the terminal is utilized to sound, so, just can avoid installing earphone and loudspeaker in the terminal, also can avoid seting up earphone phonate hole and loudspeaker phonate hole. The structure of the terminal is described below.

Fig. 1 is a schematic diagram of a terminal according to an exemplary embodiment, as shown in fig. 1, the terminal includes a housing 110, a processor 120 located in the housing 110, a driver 130, a switch 140, and n motors 150, n being a positive integer greater than or equal to 2.

The sound-producing principle of the motor 150 will be described first. Generally, the motor 150 includes a coil, a vibrator, and a permanent magnet, and when the coil is energized, the coil generates a magnetic field, which generates a force with the magnetic field generated by the permanent magnet, thereby causing the vibrator to vibrate up and down or left and right, and driving the housing 110 to vibrate, thereby generating a sound.

Compared with the motor 150, the receiver and the speaker have special diaphragms, and the diaphragms are relatively easy to deform, so that the loudness of the sound emitted by the receiver and the speaker is greater than that of the sound emitted by the motor 150 under the same conditions (such as the same voltage, current and magnetic field environments). Optionally, n (n is greater than or equal to 2) motors can be installed in the terminal, and the n motors are controlled to sound at the same time, so that the loudness of sound can be improved, and the stereo listening sensation can be created.

It should be noted that the models of the n motors 150 in the terminal may be different, or the models of the n motors 150 in the terminal may be the same, so as to create a good stereo listening experience.

When the terminal includes n motors 150, the n motors 150 may be mounted at any position in the terminal, and the mounting position of the motor 150 is not limited in the present embodiment.

In this embodiment, the processor 120 is connected to the driver 130 and the switch 140, respectively.

The processor 120 is configured to control the switch 140 to be in a closed state or an open state.

The processor 120 may be connected to the driver 130 via an I2C (Inter-Integrated Circuit) bus.

In this embodiment, the switch 140 is connected to the driver 130 and the n motors 150, respectively.

In this embodiment, n motors 150 are coupled to the housing 110.

Wherein, when the housing 110 includes a front case, a middle frame, and a rear case, the n motors 150 may be connected to the front case or the middle frame or the rear case; when the housing 110 includes a front case and an integrated rear case, the n motors 150 may be connected to the front case or the integrated rear case, which may be a combination of a middle frame and a rear case.

In this embodiment, when the switch 140 is in a closed state under the control of the processor 120, all or part of the n motors 150 drive the casing 110 to vibrate and generate sound under the driving of the sound-generating driving signal output by the driver 130.

When the switch 140 is in the closed state, the driver 130 and the motor 150 are in the open state, the driver 130 outputs the sound-generating driving signal to the motor 150, the motor 150 vibrates under the driving of the sound-generating driving signal, and the vibration of the motor 150 drives the housing 110 to vibrate, so that the sound is generated.

When the switch 140 is in the off state, the driver 130 and the motor 150 are in the off state, the driver 130 cannot output the sound-generating driving signal to the motor 150, and the motor 150 does not vibrate, which cannot drive the housing 110 to vibrate to generate sound.

It should be noted that the sound emission driving signal output by the driver 130 may be received from the processor 120, or may be generated by the driver 130, as described in detail below.

In summary, according to the terminal provided by the present disclosure, since all or part of the n motors can drive the housing to vibrate and make sound under the driving of the sound-generating driving signal output by the driver, the motors can be used to replace the speaker and the receiver, which can avoid mounting the speaker and the receiver in the terminal, thereby saving the design complexity and the production cost of the terminal, and also avoid setting the speaker sound-generating hole and the receiver sound-generating hole in the terminal, thereby making the structure of the terminal more firm, and making the appearance of the terminal more beautiful.

Three configurations of the terminal will be described below according to the number of drivers 130 and switches 140.

1. The terminal includes a driver 130 and n switches 140, and the driver 130 is connected to one motor 150 of the n motors 150 through one switch 140 of the n switches 140, respectively.

It should be noted that each switch 140 of the n switches 140 is further connected to the processor 120 through a control line 141, and each control line 141 is used for controlling the corresponding switch 140 to be in a closed state or an open state. For example, when the switch 140 is implemented by a triode, the switch 140 may be controlled to be in a closed state when the control line 141 transmits a high level, and the switch 140 may be controlled to be in an open state when the control line 141 transmits a low level; alternatively, the switch 140 may be controlled to be in a closed state when the control line 141 transmits a low level, and the switch 140 may be controlled to be in an open state when the control line 141 transmits a high level, which is not limited in this embodiment.

Assuming that n is 2, and 2 switches 140 are the first switch 140 and the second switch 140 respectively, and 2 motors 150 are the first motor 150 and the second motor 150 respectively, in one example, the driver 130 can be connected to the first motor 150 through the first switch 140, and connected to the second motor 150 through the second switch 140, please refer to fig. 2. Of course, the driver 130 is also connected to the second motor 150 through the first switch 140, and is also connected to the first motor 150 through the second switch 140, which is not limited in this embodiment.

The driver 130 may or may not include a memory, and these two cases will be described separately below.

1) When driver 130 includes a memory, i different sound effect algorithms may be stored in the memory, where i is a positive integer greater than or equal to 2.

In this embodiment, the processor 120 may send the sound signal of the sound to be played to the driver 130 when obtaining the sound signal; the processor 120 determines a target motor 150 of the n motors 150, and controls the switch 140 corresponding to the target motor 150 to be in a closed state, where the target motor 150 is all or part of the n motors 150, and the determination process is described in detail below; the driver 130 selects one of i different sound effect algorithms according to the sound signal, generates a sound generation driving signal according to the selected sound effect algorithm and the sound signal, and transmits the generated sound generation driving signal to the corresponding target motor 150 through the switch 140 in the closed state, so as to drive the target motor 150 to drive the housing 110 to vibrate and generate sound.

2) When the driver 130 does not include memory, the sound emission driving signal is generated by the processor 120 from the sound signal and transmitted to the driver 130.

In this embodiment, when obtaining the sound signal of the sound to be played, the processor 120 may generate a sound driving signal according to the sound signal, and send the sound driving signal to the driver 130; the processor 120 determines a target motor 150 of the n motors 150, and controls the switch 140 corresponding to the target motor 150 to be in a closed state; the driver 130 sends the received generation driving signal to the corresponding target motor 150 through the switch 140 in the closed state, so that the target motor 150 is driven to drive the housing 110 to vibrate and generate sound.

2. The terminal includes n drivers 130 and n switches 140, and each driver 130 is connected to one motor 150 of the n motors 150 through one switch 140 of the n switches 140, respectively.

Assuming that n is 2, and 2 drivers 130 are the first driver 130 and the second driver 130, respectively, 2 switches 140 are the first switch 140 and the second switch 140, respectively, and 2 motors 150 are the first motor 150 and the second motor 150, respectively, in one example, the first driver 130 may be connected to the first motor 150 through the first switch 140, and the second driver 130 may be connected to the second motor 150 through the second switch 140, please refer to fig. 3. Of course, the first driver 130 may be connected to the second motor 150 through the first switch 140, the second driver 130 may be connected to the first motor 150 through the second switch 140, or the first driver 130 may be connected to the second motor 150 through the second switch 140, and the second driver 130 may be connected to the first motor 150 through the first switch 140, which is not limited in this embodiment.

The driver 130 may or may not include a memory, which is described in the above 1 and is not described herein again.

3. The terminal includes m drivers 130 and m × n switches 140, and each driver 130 is connected to each motor 150 of the n motors 150 through the n switches 140, respectively, m being a positive integer greater than or equal to 2.

Assuming that m and n are both 2, and 2 drivers 130 are a first driver 130 and a second driver 130, respectively, 4 switches 140 are a first switch 140, a second switch 140, a third switch 140 and a fourth switch 140, respectively, and 2 motors 150 are a first motor 150 and a second motor 150, respectively, in one example, the first driver 130 may be connected to the first motor 150 through the first switch 140, the first driver 130 may be connected to the second motor 150 through the second switch 140, the second driver 130 may be connected to the first motor 150 through the third switch 140, and the second driver 130 may be connected to the second motor 150 through the fourth switch 140, please refer to fig. 4. Of course, the first driver 130 may be connected to the second motor 150 through the first switch 140, the first driver 130 may be connected to the first motor 150 through the second switch 140, the second driver 130 may be connected to the second motor 150 through the third switch 140, and the second driver 130 may be connected to the first motor 150 through the fourth switch 140, which is not limited in this embodiment.

The driver 130 may include a memory, among others. When the drivers 130 include a memory, and the size of the memory is limited, and all i different sound effect algorithms cannot be stored, a part of the i different sound effect algorithms may be stored in the memory of each driver 130, and the i different sound effect algorithms are stored in the memory of m drivers, where i is a positive integer greater than or equal to 2.

In this embodiment, when obtaining a sound signal of a sound to be played, the processor 120 may send the sound signal to the driver 130 storing a sound effect algorithm corresponding to the sound signal; the processor 120 determines a target motor 150 of the n motors 150, and controls the switch 140 corresponding to the target motor 150 to be in a closed state, where the target motor 150 is all or part of the n motors 150, and the determination process is described in detail below; the driver 130 receiving the sound signal selects one of the partial sound algorithms corresponding to the sound signal, generates a sound emission driving signal according to the sound effect algorithm and the sound signal, and transmits the selected sound emission driving signal to the corresponding target motor 150 through the switch 140 in the closed state, so as to drive the target motor 150 to drive the casing 110 to vibrate and emit sound.

N switches in this embodiment except can the sound production, can also carry out noiseless vibration to reach the effect of sound production and vibration simultaneously, with promotion user experience. Here, silent vibration refers to vibration that does not produce sound.

At this time, when the switch 140 is in a closed state under the control of the processor 120, all or a part of the n motors 150 drive the housing 110 to perform silent vibration by the vibration driving signal outputted from the driver 130. The transmission mode of the vibration driving signal is the same as that of the sound-generating driving signal, and is not described herein again.

As shown in fig. 4, in one example, the terminal may send a sound-emitting driving signal to the first motor 150 through the first switch 140 by using the first driver 130 to drive the first motor 150 to emit sound; the terminal may transmit a vibration driving signal to the second motor 150 through the third switch 140 using the second driver 130 to drive the second motor 150 for silent vibration.

The mounting positions of the n motors 150 in the terminal will be explained below.

1. Some of the n motors 150 are located on top of the main board 160 in the terminal and some of the motors 150 are located on the bottom of the sub-board 170 in the terminal.

In the present embodiment, the board located above the battery is referred to as a main board 160, and the board located below the battery is referred to as a sub-board 170. Of course, the plate located above the battery may be referred to as the sub-plate 170, and the plate located below the battery may be referred to as the main plate 160, but the present embodiment is not limited thereto.

Assuming n is 2, one motor 150 is located on top of the main board 160, the motor 150 being similar to a handset; a motor 150 is located at the bottom of the sub-plate 170, the motor 150 being similar to a horn, see the left side view of fig. 5.

2. The n motors 150 are all located on top of the terminal's middle main board 160; alternatively, the n motors 150 are all located at the bottom of the sub-plate 170 in the terminal.

When the n motors 150 are all located on the top of the main board 160, the n motors 150 may be arranged on the top of the main board 160 in a dispersed manner, or may be arranged on the top of the main board 160 in a concentrated manner, which is not limited in this embodiment.

When the n motors 150 are all located at the bottom of the sub-plate 170, the n motors 150 may be distributed at the bottom of the sub-plate 170 or concentrated at the bottom of the sub-plate 170, which is not limited in this embodiment. Referring to the middle view of fig. 5, two motors 150 are dispersedly arranged at the bottom of the sub-plate 170.

3. The n motors 150 are all uniformly dispersed in the terminal middle main board 160; alternatively, the n motors 150 are all evenly dispersed in the terminal mid-subplate 170.

When the n motors 150 are all uniformly distributed in the sub-plate 170, the n motors 150 may be distributed on the left and right sides of the sub-plate 170, and the embodiment is not limited.

Fig. 6 is a flowchart illustrating a sound emission method applied to the terminal shown in fig. 1 to 5 according to an exemplary embodiment, and the sound emission method includes the following steps, as shown in fig. 6.

In step 601, a sound signal of a sound to be played is acquired.

In step 602, a voicing drive signal is generated from the sound signal, with different sound signals corresponding to different waveforms of the voicing drive signal.

In step 603, the switch corresponding to the target motor of the n motors is controlled to be in a closed state, wherein the target motor is all or part of the n motors.

In step 604, the target motor is driven to vibrate the housing according to the sound-emitting driving signal to emit sound.

In summary, according to the sound production method provided by the present disclosure, the target motor is driven to drive the housing to vibrate according to the sound production driving signal to produce sound, so that the motor in the terminal has a sound production function in addition to the original vibration function, and thus, the motor can be used to replace the speaker and the receiver, which can avoid mounting the speaker and the receiver in the terminal, thereby saving the design complexity and the production cost of the terminal, and also can avoid setting the speaker sound production hole and the receiver sound production hole in the terminal, thereby making the structure of the terminal more firm, and making the appearance of the terminal more beautiful.

Fig. 7 is a flowchart illustrating a sound emission method applied to the terminal shown in fig. 1 to 5 according to another exemplary embodiment, and the sound emission method includes the following steps, as shown in fig. 7.

In step 701, a sound signal of a sound to be played is acquired.

The sound to be played may be any sound that can be heard by the human ear. For example, the sound to be played may be voice, audio, and so on. The voice may be generated during a real-time call, or may be a pre-recorded voice, etc. The audio may be a song, or a dubbing of a movie program, and the like, and the embodiment is not limited.

The audio signal is a signal representing audio, and may be an analog signal or a digital signal.

Two sound generation methods are explained below with respect to the number of motors.

1) When the terminal comprises a motor, the terminal generates a sound production driving signal according to the sound signal, and drives the motor to play sound according to the sound production driving signal.

2) When the terminal comprises n (n is more than or equal to 2) motors, the terminal can select a target motor from the n motors according to the current use scene, generate a sound production driving signal according to the sound signal, and drive the target motor to play sound according to the sound production driving signal.

When the terminal contains n motors, all the motors can be directly controlled to sound, and part of the motors can be controlled to sound according to the use scene, so that the sound production requirements of users on different use scenes are met. In this embodiment, a usage scenario is taken as an example of a play mode, and in actual implementation, a part of the motors may be controlled to generate sound according to other usage scenarios.

In the first sounding method, compared with the second sounding method, the step of selecting the target motor is omitted, and the implementation manner of the remaining steps is the same as that of the corresponding steps in the second sounding method, and the second sounding method is taken as an example to be described below.

In step 702, a play mode of the terminal is obtained, and a target motor is selected from the n motors according to the play mode.

The terminal has two play modes, i.e. a handset play mode and a play mode, and the two play modes are explained in detail as described above. The terminal has the following two setting modes in the play mode.

In a first setting, the terminal automatically selects a corresponding play mode according to the usage scenario. At this time, the terminal is preset with a corresponding relationship between the usage scene and the playing mode, and the terminal can acquire the usage scene at the current time and then search for the corresponding playing mode in the corresponding relationship. Wherein, the corresponding relationship may include: a call scenario-handset mode, a video call scenario-play-out mode, a voice message play scenario-play-out mode, and so on.

In a second setting mode, the terminal receives an operation instruction of a user, and selects a corresponding play mode according to the operation instruction. For example, the calling scene originally corresponds to the earphone mode, if the user clicks the "hands-free" control, the terminal receives an operation instruction, and switches the earphone mode to the play-out mode according to the operation instruction.

No matter what kind of setting mode the terminal sets up through above-mentioned, the terminal can all acquire self present playback mode, again according to this playback mode selection target motor. The target motor is a motor selected by the terminal for generating sound, and the number of the target motors may be one or at least two, which is not limited in this embodiment.

In a first implementation, when the playback mode is the play-out mode, all of the n motors are set as target motors.

When the play mode is the play-out mode, it indicates that the user has a requirement for playing sound loud, for example, the user is in a noisy environment, and can listen to the call content only by calling in the play-out mode; alternatively, the user plays music through a play-out mode to enjoy the stereo listening experience. In this case, the terminal may use all of the n motors as the target motors, so that the terminal may control all of the motors to generate sound, thereby increasing the loudness of the sound and creating stereo sound.

In a second implementation manner, when the play mode is the earpiece mode, a part of the motors with the installation position closest to a predetermined position is selected from the n motors, and the part of the motors is used as a target motor, wherein the predetermined position is a contact position of a human ear and the terminal when the play mode is the earpiece mode.

When the play mode is the earphone mode, it indicates that the user has a small sound play sound to protect the requirement of user privacy, at this moment, the terminal can regard partial motor among the n motors as the target motor, and like this, the terminal can control partial motor sound production, so as to reduce the loudness of sound, guarantee that user's privacy is not heard by people nearby.

In addition, when the predetermined position is a contact position of the human ear with the terminal in the earpiece mode, since the target motor selected by the terminal is closest to the predetermined position from the installation position, the sound emitted from the target motor can be clearly transmitted to the human ear.

In step 703, a sounding drive signal is generated from the sound signal.

The sound emission driving signal is a current signal for driving the motor to emit sound.

Wherein the different sound signals correspond to different waveforms of the sounding drive signal. The waveforms referred to herein differ by: the present embodiment is not limited to this, and the waveform may have different types, different frequencies, different amplitudes, and the like.

The following describes a process of generating the sound emission drive signal.

1) The processor generates a sound emission driving signal according to the sound signal.

At this time, generating the sound emission drive signal from the sound signal includes: determining a sound effect algorithm corresponding to the sound signal according to the sound signal through a processor; and generating a sound production driving signal according to the sound signal and the sound effect algorithm. The processor can generate the sound production driving signal according to the sound effect algorithm corresponding to the sound signal. The processor also sends a sound production driving signal to the driver, and the motor is driven to produce sound through the driver.

Optionally, the processor may also power amplify the sound signal and/or the voicing drive signal to increase the loudness of the sound.

2) The driver generates a sound emission drive signal from the sound signal.

At the moment, the sound signal is sent to a driver through a processor in the terminal, and the driver selects a sound effect algorithm corresponding to the sound signal from different sound effect algorithms stored in a memory; and generating a sound production driving signal according to the sound signal and the sound effect algorithm through a driver, and generating the sound production driving signal according to the sound signal.

The driver at this time has a function of generating a sound emission drive signal. Optionally, the driver in this embodiment may be a power amplifier, and then the driver may also have a function of amplifying a signal. In one example, the driver in this embodiment may be referred to as a Smart Power Amplifier (Smart PA).

Optionally, the power amplifier may further perform power amplification on the sound signal and/or the sounding driving signal to improve the loudness of the sound.

In step 704, the switch corresponding to the target motor of the n motors is controlled to be in a closed state, and the target motor is all or part of the n motors.

In this embodiment, the processor may control whether the switch corresponding to the target motor is in the closed state or the open state by transmitting a level signal on a control line connected to the switch.

In step 705, the target motor is driven to vibrate the housing according to the sound-emitting driving signal to emit sound.

The following exemplifies the sound production of the driver driving target motor in the external mode and the earpiece mode.

For example, when the play mode of the terminal is a play-out mode, assuming that Smart PA1 is used to control Motor1 and Smart PA2 is used to control Motor2, the processor may transmit sound signals to Smart PA1 and Smart PA2, respectively; the Smart PA1 generates a sound production driving signal according to a sound signal and a sound effect algorithm, and drives the Motor1 to vibrate according to the sound production driving signal, and the vibration of the Motor1 drives the shell to vibrate to produce sound; smart PA2 generates a sound-producing driving signal according to a sound signal and a sound effect algorithm, and drives a Motor2 to vibrate according to the sound-producing driving signal, and the vibration of the Motor2 drives a shell to vibrate to produce sound, so that the Motor1 and the Motor2 vibrate and produce sound at the same time.

For example, when the play mode of the terminal is a handset mode, assuming that Smart PA1 is used to control Motor1, Smart PA2 is used to control Motor2, and assuming that the processor selects Motor1 to sound, the processor may transmit a sound signal to Smart PA 1; the Smart PA1 generates a sound production driving signal according to a sound signal and a sound effect algorithm, and drives the Motor1 to vibrate according to the sound production driving signal, the vibration of the Motor1 drives the shell to vibrate to produce sound, and at the moment, the Motor2 does not vibrate; assuming the processor selects Motor2 to sound, the processor may send a sound signal to Smart PA 2; smart PA2 generates a sound production driving signal according to a sound signal and a sound effect algorithm, and drives a Motor2 to vibrate according to the sound production driving signal, the vibration of the Motor2 drives a shell to vibrate to produce sound, and at the moment, the Motor1 does not vibrate.

Optionally, when the target motor is a partial motor of the n motors, the terminal may control the target motor to sound, and may also control the remaining motors of the n motors except the target motor to perform silent vibration, so as to achieve the effect of sound production and vibration at the same time, and improve user experience. At this time, the terminal performs step 706 to drive the remaining motor for silent vibration.

In step 706, a vibration drive signal is generated from the vibration signal.

The vibration signal is acquired by the terminal, and may correspond to the current usage scenario, and the acquisition mode of the vibration signal is not limited in this embodiment.

In step 707, switches corresponding to the remaining motors of the n motors, which are motors other than the target motor, are controlled to be in a closed state.

In this embodiment, the processor may control whether the switch is in the closed state or the open state by transmitting a level signal on a control line connected to the switches corresponding to the remaining motors.

In step 708, the remaining motors are driven to silently vibrate the housing according to the vibration driving signal.

The process of generating the vibration driving signal will be explained below.

1) The processor generates a vibration drive signal from the vibration signal.

Optionally, the processor may generate a vibration driving signal according to the vibration signal and a vibration waveform algorithm, send the vibration driving signal to the driver, and drive the motor to perform silent vibration through the driver, which is not limited in this embodiment.

Optionally, the processor may further perform power amplification on the vibration driving signal to increase the amplitude of the vibration.

2) The driver generates a vibration driving signal according to the vibration signal.

At this time, the vibration signal is transmitted to a driver by a processor in the terminal, and the vibration driving signal is generated by the driver.

Optionally, the driver may generate the vibration driving signal according to a vibration waveform algorithm, and the embodiment is not limited.

When the driver is a power amplifier, the driver can simply amplify the vibration driving signal at the moment, and drive the rest motor to perform silent vibration according to the amplified vibration driving signal so as to improve the amplitude of vibration; alternatively, the driver at this time may be in Bypass mode (i.e., the signal input to the driver is the same as the signal output from the driver), i.e., the vibration driving signal is not amplified, and the remaining motor is driven to vibrate silently according to the vibration driving signal.

Referring to fig. 8, the terminal may determine a motor for sound generation and a motor for silent vibration among the 2 motors through the steps of fig. 8.

When the terminal contains n motors, all the motors can be directly controlled to sound, and part of the motors can be controlled to sound according to the use scene, so that the sound production requirements of users on different use scenes are met.

The terminal can control all the motors to sound, so that the loudness of sound can be improved, and the stereo listening sense can be created; and the terminal can control part of the motor to sound so as to reduce the loudness of the sound and ensure that the privacy of the user is not heard by people nearby.

When the predetermined position is a contact position of the human ear with the terminal in the earpiece mode, since the target motor selected by the terminal is closest to the predetermined position from the mounting position, the sound emitted from the target motor can be clearly transmitted to the human ear.

The terminal can control the target motor to sound and can also control the rest motors to perform silent vibration, so that the effects of sound production and vibration are achieved simultaneously, and the user experience is improved.
