Abstract

The application discloses a method, device and system for eliminating power-on impact sound of an audio processor, and the method comprises the following steps: measuring power-on time of each sub-module in an audio processing circuit; measuring impact voltage of an output end of the audio processing circuit according to the power-on time of each sub-module and a preset conduction time level, and obtaining an optimal power-on control signal arrangement scheme set; and adjusting the frequency of the power-on control signal sent to each sub-module according to the optimal power-on control signal arrangement scheme set, so as to eliminate the impact sound when the audio processing circuit is powered on. The application can reduce the impact voltage by adjusting the power-on time of the audio processor, and effectively eliminates the impact sound when the audio processor is powered on.
