A microphone is provided to reduce impact from an external part by fixing a protection device on a main body of a microphone through a screw connection. An inner case is connected to be a single body with an outer case. An installation groove is formed to be protruded on an upper part of the inner case. A microphone main body has a first male screw unit formed on an outer circumference plane of the inner case and a second male screw unit on an outer circumference plane of the upper case. A cartridge(20) is installed to be inserted into the installation groove of the microphone main body. A penetration hole of a protection device(30) which receives the cartridge(20) protruded to an upper part of the microphone main body is formed to be penetrated, and a first female screw unit connected to the first male screw unit is formed on an inner circumference plane of a lower part. A lower part of a micro ball(40) is opened so that the protection device(30) is inserted. A second female screw unit connected to the second male screw unit is formed on the micro ball(40). |
