The following description of the embodiments of the present invention will be made with reference to the accompanying drawings, in which it is apparent that the embodiments described below are some, but not all embodiments of the invention.
In order to better describe the audio processing method, the audio playing device and the readable storage medium according to the embodiments of the present invention, an architecture platform for executing the audio processing method is proposed herein. Referring to fig. 1, the architecture platform includes an application layer, a music playing system layer, and a driving layer, where the application layer can obtain bluetooth audio transmitted by the bluetooth module 310, audio transmitted by the line_in module 320, and generated prompt audio, then the application layer can complete the starting and closing settings of the audio playing through the music playing system layer, and simultaneously complete the association settings between the starting and closing settings of the audio and the starting and closing settings of the communication interface, and then the driving layer can complete the driving of the communication interface to complete the playing of the whole audio data.
It should be noted that, the architecture platform provided in the embodiment is for more clearly describing the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.
Referring to fig. 2, fig. 2 is a flowchart of an audio processing method according to an embodiment of the present invention, where the audio processing method is applied to an audio controller 100, and the audio controller 100 is connected to a power amplifying unit 200, and the audio processing method includes, but is not limited to, step S100 and step S200:
step S100, obtaining audio data;
step S200, adjusting the communication state between the audio controller 100 and the power amplifier unit 200 according to the start-stop state of the audio data, and adjusting the working mode of the power amplifier unit 200.
Audio data is typically transmitted in an audio data stream, and thus there must be two states of start and stop. After receiving the audio data, the audio controller 100 enables communication between the audio controller 100 and the power amplifier unit 200 when playing the audio data, so that the audio data can be output to the power amplifier unit 200; similarly, after the audio controller 100 finishes playing the audio data stream that needs to be played this time, the communication between the audio controller 100 and the power amplifier unit 200 is stopped, so that no signal is transmitted to the power amplifier unit 200 in the audio controller 100. It should be noted that, after the communication between the audio controller 100 and the power amplifier unit 200 is cut off, the power amplifier unit 200 does not need to perform signal conditioning operation, and the power amplifier unit 200 may be controlled to enter the low power consumption operation mode.
The audio processing method of the embodiment of the invention can enable and stop enabling the communication between the audio controller 100 and the power amplifier unit 200 by determining the start and stop of the audio data, so that the power amplifier unit 200 is in a communication port disconnection state when no audio data needs to be played. When no signal is input to the power amplification unit 200, the power amplification unit 200 is not required to be in a normal power consumption state, so that the power amplification unit 200 can be controlled to enter a low power consumption working mode, the power consumption is reduced to a great extent, and meanwhile, the power amplification unit 200 does not need to complete opening and closing because of the direct cut-off communication connection, thereby avoiding the generation of plosive sounds and greatly improving the user experience.
In some embodiments, step S200 includes, but is not limited to, the steps of:
if the start-stop state indicates that the audio data starts playing, communication between the audio controller 100 and the power amplifier unit 200 is enabled, so that the audio controller 100 outputs the audio data to the power amplifier unit 200.
When it is determined that the audio data needs to be played, the communication between the audio controller 100 and the power amplifier unit 200 is directly enabled, so that the audio controller 100 can output the audio data to the power amplifier unit 200. At this time, the power amplification unit 200 modulates the audio data and then transmits the modulated audio data to the speaker 400 for audio playing, and in this process, the power amplification unit 200 is in a higher power consumption state because of the normal power amplification operation.
In some embodiments, enabling communication between the audio controller 100 and the power amplifier unit 200 comprises the steps of:
the I2S communication interface between the audio controller 100 and the power amplification unit 200 is opened.
The audio data transmitted from the audio controller 100 to the power amplifier unit 200 is required to be converted through the I2S protocol, so that the audio data can be output from the audio controller 100 to the power amplifier unit 200 only by opening the I2S communication interface between the audio controller 100 and the power amplifier unit 200.
In some embodiments, step S200 further comprises the steps of:
if the start-stop state indicates that the audio data is finished playing, the communication between the audio controller 100 and the power amplification unit 200 is closed, and the power amplification unit 200 is controlled to enter a low-power consumption working mode.
When it is determined that the audio data is played, the communication between the audio controller 100 and the power amplifier unit 200 is directly turned off, so that the audio controller 100 can stop outputting the audio data to the power amplifier unit 200. At this time, the power amplifier unit 200 has no audio signal input, and no signal modulation output is required, so that after the communication between the audio controller 100 and the power amplifier unit 200 is cut off, the power amplifier unit 200 is controlled to enter a low power consumption working mode, so as to effectively reduce energy consumption. In some embodiments, a mode switching control line is connected between the power amplification unit 200 and the audio controller 100, and the signal type of the mode switching control line is changed to enable the power amplification unit 200 to enter the low power consumption operation mode or exit the low power consumption operation mode. Specifically, the mode switching control line can directly adopt high and low levels to complete the switching control of the two modes.
In some embodiments, the communication between the audio controller 100 and the power amplifier unit 200 is turned off, comprising the steps of:
the I2S communication interface between the audio controller 100 and the power amplification unit 200 is closed.
The audio data transmitted from the audio controller 100 to the power amplifier unit 200 is required to be converted through the I2S protocol, so that the purpose of stopping the output of the audio data from the audio controller 100 to the power amplifier unit 200 can be achieved only by closing the I2S communication interface between the audio controller 100 and the power amplifier unit 200.
It should be noted that, if the I2S communication interface is not turned off, the power amplifier unit 200 is still in a normal operating state even when no audio data is input by the audio controller 100, so that the entire power amplifier unit 200 is in a higher power consumption state.
The embodiment of the present invention further provides an audio processing system, which is applied to an audio controller 100, where the audio controller 100 is connected to a power amplifier unit 200, and the audio processing system includes:

Audio data is typically transmitted in an audio data stream, and thus there must be two states of start and stop. After the audio acquisition module receives the audio data, the audio output control module enables communication between the audio controller 100 and the power amplification unit 200 when playing the audio data, so that the audio data can be output to the power amplification unit 200; similarly, after the audio data stream to be played is played, the audio output control module stops enabling the communication between the audio controller 100 and the power amplifier unit 200, so that no signal is transmitted to the power amplifier unit 200 in the audio controller 100.
The audio processing system of the embodiment of the invention determines that the audio data starts playing and stops playing through the audio output control module, and can enable and stop enabling the communication between the audio controller 100 and the power amplifier unit 200, so that the power amplifier unit 200 is in a communication port disconnection state when no audio data needs to be played. When no signal is input to the power amplification unit 200, the power amplification unit 200 is not required to be in a normal power consumption state, so that the power amplification unit can be controlled to enter a low power consumption working mode, the power consumption is reduced to a great extent, and meanwhile, the power amplification unit 200 does not need to complete the opening and closing because of the directly cut-off communication connection, thereby avoiding the generation of plosive sounds and greatly improving the user experience.
