Abstract

The noise reduction microphone comprises a base, a support and a microphone body, a rotary connecting part is formed on the support, the microphone body is installed through the rotary connecting part, the top of the microphone body is detachably connected with an isolation noise reduction cover, one end of the isolation noise reduction cover is provided with an opening, and the other end of the isolation noise reduction cover is provided with multiple layers of sound insulation pieces. The sound insulation pieces are evenly provided with filling holes, the filling holes are filled with buffering cotton, gaps are reserved between the adjacent sound insulation pieces, and the buffering cotton on the adjacent sound insulation pieces is completely staggered in the axis direction of the isolation noise reduction cover. A noise reduction module is arranged in the microphone body and is connected between the positive electrode and the negative electrode of the microphone body. Through the multiple layers of sound insulation sheets and the buffer cotton filled on the sound insulation sheets in a staggered manner, most of sound waves and airflow generated during speaking can be transmitted in a zigzag manner along the buffer cotton of each layer of sound insulation sheet, the sound waves are diffracted for multiple times and are repeatedly scattered and spread, and the flow speed of the airflow tends to be gentle, so that the noise can be greatly reduced.

Description

technical field [0001] The invention relates to the field of microphone equipment, in particular to a noise reduction microphone. Background technique [0002] Microphones are often used in various large and small speech activities and various meetings, and are an essential device for people to amplify their voices. Due to the existence of environmental noise, when the microphone of the terminal collects the effective voice signal of the user, it also collects the environmental noise at the same time, and these environmental noises will cause noise interference to the effective voice collected by the terminal. Therefore, in such a terminal, it is necessary to perform noise reduction processing on the signal collected by the microphone, so as to reduce the influence of noise on the effective voice signal. There are many noise reduction processing methods for existing terminal microphones, but the structure of the noise reduction device is relatively complicated, the implemen...
