Abstract

The invention discloses an audio transmission noise reduction processor, which comprises an audio noise reduction chip, a first resistor to a third resistor, a first capacitor to a thirteenth capacitor, an inductor and a direct current power supply. Compared with the prior art, the audio transmission noise reduction processor in the invention is mounted between the audio transmission cables so that noise waves can be effectively filtered and is anti-interference; the sound quality of audio transmission is effectively improved; and the value of popularization and application is achieved.

Description

technical field [0001] The invention relates to music electronic hardware, in particular to an audio transmission noise reduction processor. Background technique [0002] Electronic musical instruments refer to musical instruments that the musician triggers electronic signals through specific means to make them use electronic synthesis technology or sampling technology to produce sounds through electro-acoustic equipment, such as electronic organs, electric pianos, electronic synthesizers, electronic drums, etc. In the prior art, in the application of electronic musical instruments, audio needs to be transmitted through audio cables, and the audio cables will be subjected to electromagnetic interference or radio interference from other electrical appliances in the environment, resulting in degradation of audio quality. Therefore, there is room for improvement. Contents of the invention [0003] The object of the present invention is to provide an audio transmission noise r...
