Microphone with improved sound inlet port

摘要

A microphone (10) comprises a housing (12) defining an inner volume and including a first exterior surface with an aperture (28) or (60) leading to the inner volume. The microphone (10) includes a transducing assembly within the housing for converting sound into an electrical signal. A sound inlet plate (50) defines, typically in combination with the first exterior surface, a passageway for transmitting sound to the aperture. The passageway receives the sound from an opening (56) in the sound inlet plate (50). The opening (56) is offset from the location at which the aperture (28) or (60) is positioned on the exterior surface. The sound inlet plate (50) is made very thin so that it does not extend substantially away from the housing (12).
