Abstract:
A microphone with narrow directivity capable of obtaining high directivity and reducing wind noise is obtained. A cylindrical acoustic tube, a microphone unit arranged in the acoustic tube, a front acoustic chamber and a rear acoustic chamber formed by partitioning the acoustic tube by the microphone unit, a front acoustic terminal for causing the front acoustic chamber to communicate with an external space, a rear acoustic terminal for causing the rear acoustic chamber to communicate with an external space, and a film that covers the front acoustic terminal are comprised. It is recommended that the rear acoustic terminal be also covered with a film. Further, it is recommended that the films be made of vinyl chloride and formed into a corrugated shape.
