Audio processing circuit, method and electronic device, computer readable storage medium

Abstract

The present application relates to an audio processing circuit, an audio processing method, an electronic device, and a computer-readable storage medium. The audio processing circuit includes a digital signal processing module, an audio decoding module, an audio power amplifier module and a power supply module. The audio decoding module is connected between the digital signal processing module and the audio power amplifier module, and the power supply module is connected to the digital signal processing module and the audio power amplifier module. The digital signal processing module is configured to: obtain the original digital audio signal according to the audio file to be played; obtain the voltage input by the power supply module, and when the identification voltage is lower than the preset voltage value, attenuate the original digital audio signal and convert the attenuated digital The audio signal is sent to the audio decoding module; the audio decoding module is used to convert the attenuated digital audio signal into an analog audio signal, and send the analog audio signal to the audio power amplifier module. When the above-mentioned electronic equipment is in a low-voltage state, the sound it broadcasts will not be distorted and the sound quality is good.

Description

technical field [0001] The present application relates to the technical field of consumer electronic equipment, and in particular to an audio processing circuit, an audio processing method, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the continuous development of electronic technology, electronic devices such as smart phones or tablet computers have become electronic devices commonly used by users. These electronic devices usually have an audio output function to provide users with services such as audio communication and music entertainment. [0003] There are many methods for audio output of existing electronic devices, and there are two common methods, one is to output audio through earphones, and the other is to output audio through speakers. The way to output audio through the speaker is due to the voltage input and output of the audio output power amplifier, and the output audio quality is easily affected by the bat...

AI Technical Summary

Problems solved by technology

The way to output audio through the speaker is due to the voltage input and output of the audio output power amplifier, and the output audio quality is easily affected by the battery power.

When the battery power of the electronic device is low, the way to output audio through the speaker will cause the audio output to be prone to distortion
