101. an audio signal for driving the speaker is acquired.

Specifically, the audio signal is converted from a sound file of the mobile terminal, and the sound file may be received by the mobile terminal in real time or pre-stored in the mobile terminal. For example, when the mobile terminal is running a game application, the mobile terminal generates a sound file in real time based on the operation of the user on the target object in the game, and converts the sound file into a corresponding audio signal based on the operation, and for example, the sound file may be a music file pre-stored in the mobile terminal, and the music file is downloaded by the user or pre-stored in a corresponding storage, and is directly converted into a corresponding audio signal based on the music file when used.

102. Generating a vibration signal of the vibration motor according to the audio signal;

specifically, the vibration signal of the vibration motor is generated based on the audio signal, and when the signal intensity is expressed, the intensity of the vibration signal corresponds to the intensity of the audio signal, so that the user feels consistent with the auditory feeling in the sense of touch, and the experience of the user on the application scene in the sense of sound and touch is improved.

103. And simultaneously driving a loudspeaker to sound and driving the vibration motor to vibrate based on the audio signal and the vibration signal.

In order to improve the user experience of the application scene, the consistency in sound and touch is achieved, in the embodiment, the audio signal and the vibration signal drive the loudspeaker and the vibration motor simultaneously (synchronously).

In this embodiment, the mobile terminal comprises at least one speaker and one vibration motor, wherein, taking the case of having one speaker and one vibration motor as an example, in this case, the speaker and the vibration motor are generally located at the same side position of the mobile terminal. When the loudspeaker produces sound, the vibration motors on the same side can simultaneously produce vibration with corresponding strength.

To achieve a better stereo experience, some mobile terminals currently have at least two or more speakers.

As a further improvement, in order to achieve higher experience of sense of touch and sense of hearing in application scenes, the mobile terminal in this embodiment also has at least two or more vibration motors, the number of which may be the same as the number of speakers, or at least in the azimuth layout of the speakers, which can correspond to it, such as in the case of two speakers on one side, there may be only one vibration motor on the same side.

The description will be given taking an example in which the speakers include at least a first speaker and a second speaker, and the vibration motors include at least a first vibration motor and a second vibration motor; the first loudspeaker and the first vibration motor are arranged on the same side of the mobile terminal; the second loudspeaker and the second vibration motor are arranged on the same side of the mobile terminal; the first loudspeaker and the second loudspeaker are respectively located on different sides of the mobile terminal, and the first vibration motor and the second vibration motor are respectively located on different sides of the mobile terminal. At this time, the audio signal includes a first channel signal and a second channel signal, and step 102 specifically includes:

1021, generating a first vibration signal according to the first channel signal;

1022, a second vibration signal is generated according to the second channel signal.

In an application scene, the target object moves from the first side to the second side, based on the realization of the stereo effect, the intensities of the audio signals of the first speaker 11 and the second speaker 12 are different, so that the user can determine the moving direction of the target object from the stereo, and meanwhile, in order to further improve the user experience (enhance the spatial positioning effect of the user in the application scene, and obtain a more immersive experience feeling), the intensity of the vibration signal of the first vibration motor 21 corresponds to the intensity of the audio signal of the first speaker 11, and the intensity of the vibration signal of the second vibration motor 22 corresponds to the strong team of the second speaker 12. The concrete expression in a time period is that the intensity of the sound emitted by the first loudspeaker 11 gradually decreases and the intensity of the sound emitted by the second loudspeaker 12 gradually increases during the movement of the target object from the first side to the second side, and simultaneously, the intensity of the vibration of the first vibration motor 21 gradually decreases and the intensity of the vibration of the second vibration motor 22 gradually increases, so that the movement of the target object from the first side to the second side can be sensed both acoustically and tactually.

Compared with the related art, in the loudspeaker and the driving method of the vibration motor, the driving signals aiming at the vibration motor are simultaneously generated based on the audio signals of the loudspeaker, particularly in a mobile terminal with a plurality of loudspeakers, the strength of the audio signals of different loudspeakers is different for realizing the stereo effect, based on the strength, the vibration signals with the signal strength corresponding to the strength of the loudspeaker at the same side position are generated aiming at the vibration motors at different positions, and the loudspeaker and the vibration motor are simultaneously driven based on the audio signals and the vibration signals, so that the touch vibration feeling is combined on the stereo effect, and the better scene feeling when a user uses the vibration motor is further improved.
