Abstract
Disclosed in the utility model is a microphone that comprises a housing and an insulated cavity accommodated in the housing. Projecting portions that are used for realizing close clamping of the housing and the insulated cavity are arranged at the inner side wall or the outer side wall of the insulated cavity; and except the projecting portions, the size of the outer side wall of the insulated cavity is less than that of the inner side wall of the housing. When the microphone is assembled, the insulated cavity can be locally localized in the housing and is supported by the projecting portions; and then the whole insulated cavity is pressed into the housing, so that the assembling of the insulated cavity and the housing can be realized easily. Meanwhile, the projecting portions are used to realize firm clamping of the insulated cavity and the housing.
