Abstract

The invention discloses an audio playing control method and apparatus, and an audio playing device and system, applied to an audio playing system. The audio playing system comprises an audio playing device and an audio output device for outputting an audio signal to the audio playing device. The audio playing control method comprises the following steps: detecting whether a power input end of theaudio playing device is powered off, when a power-off signal of the power input end is detected, outputting a power-off detection signal; and when the power-off detection signal is received, controlling the volume of the audio signal output by the control audio output device to progressively decrease according to a preset size until the target volume value is reached. When the power input end is powered off, the POP noise generated by the audio playing device due to the power off can be avoided.

Description

technical field [0001] The present invention relates to the field of audio technology, in particular to an audio playback control method and device, audio playback equipment and system. Background technique [0002] The stereo is a kind of audio playback device, generally composed of two parts: an audio output end and an audio playback end, and an analog audio signal is output from the audio output end to the audio playback end for playback. However, in the process of the audio output terminal controlling the audio playback terminal to output audio signals, there will be a sudden power failure at the audio playback terminal. At this time, because the audio output terminal cannot know the power failure of the audio playback terminal, the audio output terminal continues to output The analog audio signal is sent to the audio playback end, so that the analog audio signal input to the audio playback end changes suddenly, resulting in POP noise at the audio playback end.
