The embodiments of the present invention provide embodiments of audio playback control methods, it being noted that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than what is shown or described herein.
In this embodiment, the audio play control method includes:
step S10, when the smart phone currently carries out voice call in a receiver state, audio data to be played are obtained;
in this embodiment, the stereo technology is a technology capable of effectively enhancing listening experience of a user, and has azimuth sense and distribution sense of each sound source, so that definition and intelligibility of information are improved, and presence sense, layering sense and transparency of a program are improved. At present, more and more mobile phones begin to apply stereo technology, generally, the mobile phones are required to have at least two groups of sounding units and more than two groups of sounding units, the sounding units are divided into left and right sound channels, and when multimedia playing is performed, different sound channels play corresponding different sound sources, so that users can have stereo hearing feeling. The full screen becomes a big trend of the mobile phone, so that the space of the loudspeaker is likely to be extruded, the traditional scheme of realizing stereo through double loudspeakers is not feasible, and various manufacturers begin to choose and reject in a limited space.
It should be noted that the invention is mainly applied to a smart phone with a dual-speaker design, wherein two groups of speakers are arranged up and down, and are symmetrically designed, and the sound emitting mode is side sound emitting, so that the front screen is prevented from being perforated. Meanwhile, an exciter is attached below the screen for sounding the screen. Sounding is carried out through the vibration screen of the exciter, and the voice-activated intelligent mobile phone can be used as a supplement of medium and low frequencies to work together with a loudspeaker of the intelligent mobile phone, so that a conversation effect similar to that of a traditional earphone can be obtained.
Specifically, the invention is mainly used for making the screen sound by the vibration of the screen caused by the exciter under the voice call scene of the mobile phone in the state of the telephone receiver, and then the loudspeaker of the mobile phone is matched, so that the effect of replacing the traditional telephone receiver is achieved. When the smart phone currently carries out voice call in the earphone state, the voice signal is sent to the smart phone by the base station, the voice signal is demodulated through the modem, and the audio data to be played is the demodulated voice signal.
Step S20, determining a high-frequency component corresponding to the audio data to be played and a middle-low frequency component corresponding to the audio data to be played based on the intelligent power amplifier;
in this embodiment, each speaker is connected to a Smart PA Smart power amplifier and a driver circuit, and the driver for sounding the screen has a Smart PA and a driver circuit, as shown in fig. 3, where the speaker and the driver circuit are independent of each other and can cooperate. In fig. 3, the top speaker is set to work, audio data to be played is input into Smart PA corresponding to the top speaker and Smart PA corresponding to the exciter, each Smart PA uses the EQ equalizer to adjust the frequency response of signals in the DSP, the Smart PA corresponding to the speaker outputs high frequency components corresponding to the audio data to be played, and the Smart PA corresponding to the exciter outputs middle and low frequency components corresponding to the audio data to be played.
And step S30, playing the high-frequency component through the top loudspeaker or the bottom loudspeaker, and playing the medium-low frequency component through an exciter.
In the embodiment, as the invention is applied to the smart phone with the double-speaker design, two groups of speakers are arranged up and down, and are symmetrically designed, the sound emitting mode is side sound emitting, and the front screen is prevented from being perforated; however, when the mobile phone performs a voice call in a handset state, the speaker is a side-out sound, so that the loss of medium and low frequencies is serious, and the listening effect of the user is affected to a certain extent. In view of the above, the invention adopts the built-in exciter in the mobile phone, and sounds through the vibrating screen as the supplement of middle and low frequencies, so that the high frequency component corresponding to the audio data to be played is played through the loudspeaker, the loudspeaker comprises a top loudspeaker and a bottom loudspeaker, and the specific choice of which loudspeaker is determined according to the actual application scene; the middle-low frequency component corresponding to the audio data to be played is played through the exciter, so that the effect of the traditional earphone is achieved.
Further, in an embodiment, the audio playing control method further includes:
step S40, obtaining a vibration signal, and carrying out power amplification on the vibration feedback signal based on a fifth intelligent power amplifier corresponding to the exciter;
and S50, playing the vibration signal with amplified power through an exciter.
In this embodiment, the actuator may be used as a motor, for example, to provide vibration feedback necessary for a game scene when a user plays a game. As shown in fig. 4, when a user plays a game, the smart phone detects a multimedia audio signal and a vibration feedback signal, and in general, the multimedia audio signal includes left and right channels, which can be played through a top speaker and a bottom speaker, respectively, so as to achieve a stereo effect; the vibration feedback signal is subjected to power amplification through an intelligent power amplifier corresponding to the exciter.
Further, when the intelligent power amplifier corresponding to the exciter detects the vibration feedback signal, the intelligent power amplifier corresponding to the exciter amplifies the vibration feedback signal, and then the intelligent mobile phone plays the vibration signal after power amplification through the exciter, so that screen vibration is realized, and the intelligent mobile phone generates vibration feedback. The exciter is used as a motor, so that the timeliness of screen vibration and vibration feedback can be better realized, and meanwhile, the motor of the smart phone can be saved.
According to the audio playing control method, when the smart phone is in a voice call in a receiver state, audio data to be played is obtained, then a high-frequency component corresponding to the audio data to be played and a middle-low frequency component corresponding to the audio data to be played are determined based on the intelligent power amplifier, the high-frequency component is played through the top loudspeaker or the bottom loudspeaker, and the middle-low frequency component is played through the exciter. The screen vibration is caused by the exciter to sound the screen, and the screen vibration is used as a supplement of medium and low frequencies to work cooperatively with a loudspeaker of the smart phone, so that the audio quality of the mobile phone in the state of a telephone receiver is improved, and the conversation effect similar to that of a traditional telephone receiver is realized.

Therefore, the exciter vibrates the screen to sound, and as a supplement of middle and low frequencies, the high-frequency component corresponding to the audio data to be played is played through the top loudspeaker, and the middle and low-frequency component corresponding to the audio data to be played is played through the exciter, so that the effect of the traditional earphone is achieved.
According to the audio playing control method, frequency equalization is conducted on the audio data to be played through the first intelligent power amplifier corresponding to the top loudspeaker, so that a first high-frequency component corresponding to the audio data to be played is obtained, and then frequency equalization is conducted on the audio data to be played through the second intelligent power amplifier corresponding to the exciter, so that a first middle-low frequency component corresponding to the audio data to be played is obtained. The frequency response of the signal is adjusted by using an EQ equalizer in the DSP of the intelligent power amplifier, so that the high-frequency component and the middle-low frequency component corresponding to the audio data to be played are successfully separated.
