Abstract

The invention discloses an anti-noise microphone with high electromagnetic compatibility, which belongs to the technical field of microphones, and comprises a shell and a microphone assembly, and further comprises: a hollow cavity positioned in the shell; the connecting seat that is connected in the hollow cavity, and the microphone assembly is connected in the connecting seat; the second sound-absorbing sponge that is connected into the shell in a sliding manner; the fixed network cable that is fixedly connected in the shell and is attached to the second sound absorption sponge; and the threaded sleeve that is in threaded connection with one end of the shell, wherein a hollow net is arranged on the threaded sleeve, and a fixing mechanism capable of compressing and fixing the network cable and the microphone assembly at the same time is arranged in the threaded sleeve. When the anti-noise microphone with high electromagnetic compatibility is used, the microphone assembly is suspended in the hollow cavity; meanwhile, the first sound-absorbing sponge and the second sound-absorbing sponge are matched with each other, so that the anti-noise effect is greatly improved, and the sound of a speaker can be heard clearly.

Description

technical field [0001] The invention relates to the technical field of microphones, in particular to an anti-noise microphone with high electromagnetic compatibility. Background technique [0002] A microphone, also known as a microphone or microphone, is a transducer that converts sound into electrical signals. [0003] In large-scale outdoor activities or some meetings, in order to facilitate the participants to clearly hear the speaker's speech, microphones are widely used, so the demand for microphones is also increasing. [0004] However, the existing high electromagnetic compatibility microphones currently on the market, when used, due to some activities or meetings, there are many people, equipment, and noise sources, and the microphone has no anti-noise function, which will cause the surrounding background noise to be suppressed. The microphone picks up and transmits it to the terminal device, and there will be more noise, which will cause other people to be unable ...
