I saw a disgusting joke on the Internet: in a singing program, an old singer coughed after singing, spit out a mouthful of old phlegm on the microphone, secretly wiped off the phlegm while no one noticed, handed the microphone to the next young singer, and then watched the young singer lick the microphone while singing in the audience.
Back to reality, there is a layer of sponge foam in the microphone grid, which is very easy to accumulate bacteria, but almost no one will take care of the microphone, and it is reported on the Internet that the public microphone was infected with the new coronavirus at a men's annual meeting in Liaoning in 2020. Therefore, this microphone anti-foam cover was designed.
The components include the shelf on the microphone and the cover frame on the top, both of which have magnets, each with a cover frame, and the cover is covered with anti-foam cloth. Because of the magnet, it is not easy to get rid of the cover frame. Each person has a separate cover frame to form isolation on the microphone to prevent infection. (Designed in early 2020)
