Abstract
The utility model discloses a condenser microphone explosion-proof device. A mounting frame of the utility model is composed of two opposing mounting outer frames. The outside of the edge of each mounting outer frame is protruding inwards to form a mounting boss. Each mounting boss is provided with an explosion-proof net. One explosion-proof net is connected with a blowout prevention net through a middle mounting frame. The blowout prevention net is connected with the other explosion-proof net through a middle connection frame. The two explosion-proof nets and the blowout prevention net are coordinately connected together through the mounting frame, the middle mounting frame and the middle connection frame to form a condenser microphone explosion-proof device which can exclude electromagnetic interference, prevent audio frequency impact, eliminate outside noise, and clean recording effect. The condenser microphone explosion-proof device is simple in structure, convenient to use, and excellent in explosion-proof performance, and can be widely used.
