Abstract
A microphone comprises a housing defining an inner volume and including a first exterior surface with an aperture leading to the inner volume. The microphone includes a transducing assembly within the housing for converting sound into an electrical signal. A sound inlet plate 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 in the sound inlet plate. The opening is offset from the location at which the aperture is positioned on the exterior surface. The sound inlet plate is made very thin so that it does not extend substantially away from the housing.
