STEREO HEADSET, TERMINAL, AND AUDIO SIGNAL PROCESSING METHODS THEREOF

摘要

A audio signal processing method includes: sampling and holding, in a time sharing manner, an audio-left channel analog signal output by an audio-left channel microphone of a stereo headset and an audio-right channel analog signal output by an audio-right channel microphone; performing analog-to-digital conversion on the audio-left channel analog signal and audio-right channel analog signal that are sampled and held, so as to obtain a corresponding audio-left channel digital signal and an audio-right channel digital signal; performing data encapsulation on the audio-left channel digital signal and the audio-right channel digital signal to obtain a serial digital signal; and receiving and demodulating, by a terminal, the serial digital signal to obtain an audio-left channel digital signal and an audio-right channel digital signal.

1. An audio signal processing method of a stereo headset, wherein the stereo headset comprises a left-ear headset unit, a right-ear headset unit, and an external plug configured to connect to an external terminal, the external plug comprises a microphone port, the left-ear headset unit comprises an audio-left channel microphone and an audio-left channel headset, the right-ear headset unit comprises an audio-right channel microphone and an audio-right channel headset, and the method comprises:
sampling and holding, in a time sharing manner, an audio-left channel analog signal output by the audio-left channel microphone and an audio-right channel analog signal output by the audio-right channel microphone; performing analog-to-digital conversion on the audio-left channel analog signal and audio-right channel analog signal that are sampled and held, so as to obtain a corresponding audio-left channel digital signal and a corresponding audio-right channel digital signal; performing data encapsulation on the audio-left channel digital signal and the audio-right channel digital signal to obtain a serial digital signal; and transmitting the serial digital signal to the external terminal by using the microphone port of the external plug.
