Noise reduction device for vehicle-mounted radio station

The utility model provides a noise reduction device for a vehicle-mounted radio station. The noise reduction device is connected with a short-wave/ultra-short-wave radio station through a cable. The device comprises a first audio output module and a noise reduction module connected with the first audio output module, and the noise reduction module is further connected with a second audio output module. And the noise reduction module is directly connected with the output interface of the first audio output module, performs noise reduction identification and processing on the audio, and directly outputs the audio to the first audio output module or the second audio output module, thereby realizing voice noise reduction and volume adjustment functions. The device has an independent structure, can be conveniently disassembled and connected, can be used as required, and does not influence the original vehicle-mounted function or damage the vehicle-mounted structure. The system is simple in structure and low in imp
