A Loudspeaker Noise Reduction Method Based on Feiteng Platform

Abstract

The invention discloses a loudspeaker noise reduction method based on a Feiteng platform. The specific implementation process is as follows: comprising a PSOC chip, the PSOC chip is connected to an audio control chip and a loudspeaker through an explosion sound elimination module, and the audio control module and the loudspeaker are mutually The audio control module is also connected to the USB HUB controller through the USB interface. The USB HUB controller is connected to the CPU chip through the coprocessor; to the speaker. Compared with the prior art, this loudspeaker noise reduction method based on the Feiteng platform can add the audio output device of the explosion sound elimination module, which can filter out the explosion sound generated when the audio chip is powered on and off, and can be greatly improved. Improve the sound output quality of audio equipment and realize the noise filtering function.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a highly practical loudspeaker noise reduction method based on a Feiteng platform. Background technique [0002] For equipment with audio output, the audio power amplifier is an important part of the system. Its performance and whether it can work normally and stably play a decisive role in the equipment. When the existing audio and video output equipment is turned on or off, or When the device enters sleep, hibernate and wakes up in the above states, its audio control chip often produces pop noise at the moment of power supply and power failure, which affects people's normal use. In order to improve product quality, the present invention provides a loudspeaker noise reduction method based on the Feiteng platform. In this method, an explosion sound elimination module is added to the notebook motherboard of the Feiteng platform, and the noise source itself is started, and the ex...
