Abstract

The invention relates to the technical field of audio processing, in particular to a noise reduction device for audio equipment and a noise reduction method.The noise reduction device comprises an audio equipment body, an input port, an output port and a fan body, and a noise reduction layer is arranged on the surface of the inner wall of the audio equipment body; a receiving module, a scene detection algorithm module and a filtering noise reduction module are arranged in the audio equipment body. Noise and vibration generated by a cooling fan of the device can be absorbed, so that the influence of the noise generated by the cooling fan on audio is reduced, meanwhile, the device can also recognize a noise scene where an audio signal is located, perform noise reduction processing on the audio signal and compensate the audio signal in the filtering and noise reduction process, and the noise reduction effect of the audio signal is improved. Therefore, the quality of the audio signal after noise reduction is improved, the audio signal output by the audio equipment is prevented from being noisy or distorted, and normal operation of the audio equipment is facilitated.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a noise reduction device and a noise reduction method for audio equipment. Background technique [0002] Audio equipment is mainly a general term for audio input and output equipment, which includes many types of products, which can generally be divided into the following categories: power amplifiers, speakers, multimedia consoles, digital mixers, audio sampling cards, synthesizers, medium and high Audio speakers, microphones, sound cards in PCs, headphones, etc., and other peripheral audio equipment: professional microphone series, headphones, radio and amplification systems, etc. Sound quality is an important criterion for judging the quality of audio equipment, including signal-to-noise ratio, sampling bits, sampling frequency, total harmonic distortion and other indicators. The level of these parameters determines the sound quality of audio equipment. [0003] Audio...
