The embodiments of the present disclosure provide an embodiment of an audio playback control method. It should be noted that although the logical sequence is shown in the flowchart, in some cases, the sequence shown or shown may be executed in a different order than here. Describe the steps.

In this embodiment, the audio playback control method includes:

Step S10: Acquire audio data to be played when the smart phone is currently performing a voice call in the earpiece state;

In this embodiment, the stereo technology is a technology that can effectively enhance the user's listening experience. It has the sense of orientation and distribution of each sound source, improves the clarity and intelligibility of information, and improves the sense of presence of the program. Layering and transparency. At present, more and more mobile phones begin to use stereo technology. Generally, mobile phones are required to have at least two or more sound units, divided into left and right channels. When playing multimedia, different channels correspond to different sound sources to ensure users Can have a three-dimensional listening experience. Full screens have become a major trend in mobile phones, which will inevitably squeeze the speaker space. The traditional solution of achieving stereo through dual speakers is no longer feasible, and major manufacturers have begun to make choices in limited space.

It should be noted that the present disclosure is mainly applied to a smart phone with a dual-speaker design. The two sets of speakers are arranged up and down with a symmetrical design. The sound output method is side sound to avoid openings on the front screen. At the same time, an exciter is attached to the bottom of the screen for screen sound. Sound is produced by vibrating the screen through the exciter, as a supplement to the low frequency, and working in conjunction with the speaker of the smart phone, can obtain a call effect similar to a traditional earpiece.

In one embodiment, the present disclosure is mainly used in a voice call scenario where the mobile phone is in the earpiece state, and the exciter causes the screen to vibrate to produce screen sound, and then cooperate with the speaker of the mobile phone to achieve the effect of replacing the traditional earpiece. When the smart phone is currently performing a voice call in the earpiece state, the voice signal is sent from the base station to the smart phone, and the voice signal is demodulated through the modem, and the audio data to be played is the demodulated voice signal.

Step S20: Determine, based on the smart power amplifier, a high frequency component corresponding to the audio data to be played and a middle and low frequency component corresponding to the audio data to be played;

In this embodiment, each speaker is connected to its own smart power amplifier (Smart PA, Smart Power Amplifier) and drive circuit, and the exciter used for screen sound has a special Smart PA and drive circuit, as shown in Figure 3. Shows that the circuits of the speaker and the exciter are independent of each other and can work together. In Figure 3, the top speaker is set to work, and the audio data to be played is input into the Smart PA corresponding to the top speaker and the Smart PA corresponding to the exciter at the same time. The digital signal processor (DSP, Digital Signal Processing) of each Smart PA uses equalization. The Equalizer (EQ, Equalizer) adjusts the frequency response of the signal. The Smart PA corresponding to the speaker outputs the high-frequency components corresponding to the audio data to be played, and the Smart PA corresponding to the exciter outputs the mid- and low-frequency components corresponding to the audio data to be played.

In step S30, the high frequency component is played through the top speaker or the bottom speaker, and the middle and low frequency component is played through an exciter.

In this embodiment, since the present disclosure is applied to a smart phone with a dual-speaker design, the two sets of speakers are arranged up and down, and the design is symmetrical. The sound output method is side sound, avoiding the opening of the front screen; however, the phone performs the voice in the earpiece state During a call, because the speaker is a side speaker, the mid- and low-frequency loss is more serious, which affects the user's listening effect to a certain extent. In view of this, the present disclosure adopts the built-in exciter in the mobile phone to produce sound through the vibrating screen as a supplement to the medium and low frequencies. Therefore, the high frequency components corresponding to the audio data to be played are played through the speakers. The speakers include a top speaker and a bottom speaker. The specific selection is Which speaker is determined according to the actual application scenario; the mid- and low-frequency components corresponding to the audio data to be played are played through the exciter to achieve the effect of a traditional earpiece.

In one embodiment, in one embodiment, the audio playback control method further includes: step S40, obtaining a vibration signal, and performing power amplification on the vibration feedback signal based on a fifth smart power amplifier corresponding to the exciter; S50: Playing the amplified vibration signal through the exciter.

In this embodiment, the exciter can be used as a motor, for example, when the user is playing a game, it provides necessary vibration feedback for the game scene. As shown in Figure 4, when the user is playing a game, the smartphone detects the multimedia audio signal and the vibration feedback signal. Generally, the multimedia audio signal includes left and right channels, which can be played through the top speaker and the bottom speaker, respectively. Stereo effect; the vibration feedback signal is amplified by the intelligent power amplifier corresponding to the exciter.

In one embodiment, when the smart power amplifier corresponding to the exciter detects the vibration feedback signal, the smart power amplifier corresponding to the exciter amplifies the vibration feedback signal, and then the smart phone plays the amplified vibration signal through the exciter. To achieve screen vibration, the smartphone generates vibration feedback. The exciter is used as a motor, which can better realize the timeliness of screen vibration and vibration feedback, and at the same time can save the motor of the smart phone.

The audio playback control method proposed in this embodiment acquires audio data to be played when the smart phone is currently performing a voice call in the earpiece state, and then determines the high-frequency components and the corresponding high-frequency components of the audio data to be played based on the smart power amplifier. For the mid-low frequency components corresponding to the audio data to be played, the high-frequency components are then played through the top speaker or the bottom speaker, and the mid-low frequency components are played through the exciter. The exciter causes the screen to vibrate for screen sound. As a supplement to the mid-low frequency, it works in conjunction with the smart phone's speaker to improve the audio quality when the phone is in the earpiece state and achieve a call effect similar to a traditional earpiece.

Based on the first embodiment, referring to FIG. 5, a second embodiment of the audio playback control method of the present disclosure is proposed. In this embodiment, step S20 includes: step S21, based on the first smart power amplifier corresponding to the top speaker, The audio data to be played is frequency equalized to obtain the first high frequency component corresponding to the audio data to be played; step S22, based on the second smart power amplifier corresponding to the exciter, frequency is performed on the audio data to be played Equalize to obtain the first middle and low frequency component corresponding to the audio data to be played.

Each speaker has its own Smart PA smart power. The amplifier and the drive circuit are connected, and the exciter used for screen sound has a special Smart PA and drive circuit. The circuits of the speaker and the exciter are independent of each other and can work together. In this embodiment, when the smart phone makes a voice call in the earpiece state, the top speaker works by default, and the audio data to be played is input into the Smart PA corresponding to the top speaker and the Smart PA corresponding to the exciter at the same time. Each SmartPA comes with its own DSP The EQ equalizer is used to adjust the frequency response of the signal. The Smart PA corresponding to the speaker outputs the high-frequency components corresponding to the audio data to be played, and the Smart PA corresponding to the exciter outputs the mid- and low-frequency components corresponding to the audio data to be played.

In one embodiment, in one embodiment, step S30 includes: playing the first high frequency component through the top speaker, and playing the first middle and low frequency component through the exciter.

In this embodiment, the top and bottom speakers of the dual-speaker smart phone are designed symmetrically, and the sound output method is side sound, avoiding the opening of the front screen. When the mobile phone makes a voice call in the earpiece state, because the speaker is side sound, the middle speaker The low frequency loss is more serious, which affects the user's listening effect to a certain extent. Therefore, the exciter is used to vibrate the screen to produce sound. As a supplement to the low and medium frequencies, the high frequency components corresponding to the audio data to be played are played through the top speaker, and the medium and low frequency components corresponding to the audio data to be played are played through the exciter to achieve the effect of a traditional earpiece.

The audio playback control method proposed in this embodiment performs frequency equalization on the audio data to be played based on the first smart power amplifier corresponding to the top speaker to obtain the first high frequency component corresponding to the audio data to be played. Then, based on the second smart power amplifier corresponding to the exciter, frequency equalization is performed on the audio data to be played to obtain the first mid-low frequency component corresponding to the audio data to be played. The EQ equalizer is used in the built-in DSP of the smart power amplifier to adjust the frequency response of the signal, so as to successfully separate the high frequency component and the low frequency component corresponding to the audio data to be played.

In one embodiment, when the user is holding a call, it is determined that the current mobile phone is in a normal holding state according to the three-dimensional posture orientation data of the posture sensor, that is, relative to the human ear, the top speaker is on the top and the bottom speaker is on the bottom. For speaker playback conditions, determine the top speaker as the target speaker, that is, the top speaker and exciter 1 of the first group as the target speaker and target exciter respectively; on the contrary, if the current mobile phone is determined to be abnormally held according to the three-dimensional attitude data of the attitude sensor State, that is, relative to the human ear, the top speaker is down and the bottom speaker is up. At this time, the playback conditions of the top speaker are not met, the bottom speaker is determined as the target speaker, that is, the bottom speaker and exciter 2 of the second group are respectively the target speaker And goal stimulator.

Step S24: Perform frequency equalization on the audio data to be played based on the third smart power amplifier corresponding to the target speaker to obtain the second high frequency component corresponding to the audio data to be played;

In this embodiment, as shown in Figure 8, the upper frame of the smart phone is equipped with a top speaker, the lower frame is equipped with a bottom speaker, and the back of the screen of the smart phone is equipped with 2 exciters. The power amplifier and the drive circuit are connected, and the two exciters used for screen sound also have their own dedicated Smart PA and drive circuit. The circuits of the speaker and the exciter are independent of each other and can work together. In this embodiment, when the smart phone makes a voice call in the earpiece state, after determining the target speaker and the target exciter according to the parameters of the attitude sensor, the audio data to be played is simultaneously input into the SmartPA intelligent power amplifier and the target exciter corresponding to the target speaker. The corresponding Smart PA smart power amplifier, each Smart PA's built-in DSP uses an EQ equalizer to adjust the frequency response of the signal, the Smart PA corresponding to the speaker outputs the high-frequency components corresponding to the audio data to be played, and the Smart PA corresponding to the exciter Output the middle and low frequency components corresponding to the audio data to be played.

When the mobile phone makes a voice call in the earpiece state, because the speaker is side sound, the middle speaker The low frequency loss is more serious, which affects the user's listening effect to a certain extent. Therefore, the sound is produced through the vibrating screen as a supplement to the medium and low frequencies. Therefore, the high frequency components corresponding to the audio data to be played are played through the target speaker, and the medium and low frequency components corresponding to the audio data to be played are played through the target exciter, so as to achieve the effect of a traditional earpiece.
