摘要
The stereo boundary microphone includes a boundary plate, a case body attached to the boundary plate and having an elongate shape including left and right grooves provided in opposite sides and extending along the longitudinal direction, first and second side walls covering the grooves included in the case body by predetermined distances to form left and right acoustic passages, and first and second microphones contained in tail end portions of the acoustic passages so as directional axes of the first and second microphones to be parallel. An opening communicating with the tail end portion of the case body is provided and services as a rear acoustic terminal to be used by both the first and second microphones. Front ends of the acoustic passages formed by the side walls serve as left and right front acoustic terminals of the first and second microphones.
