    摘要: A differential microphone which includes a plate positioned between and spanning the sound-receiving opening of the microphone. Carried by the plate is a transducer having opposed sound entries surrounded by one or more bores which extend through the plate. The plate serves to delay sound reception at one transducer sound entry.
