PROBLEM TO BE SOLVED: To provide a condenser microphone array capable of obtaining directivity with a single array. SOLUTION: A plurality of condenser microphone array constituents 11 are integrated in a juxtaposed state to form the condenser microphone array 10. The condenser microphone array 10 is formed by dicing a laminate of a circuit board forming member, a casing forming member, a spacer forming member, a diaphragm sheet, a diaphragm plate forming member, and a cover forming member which constitute a part of the plurality of condenser microphone array constituents 11. A back plate 15 and a contact spring 14 are incorporated into an air chamber 23 of each of the condenser microphone constituents 11 constituted in the laminate. COPYRIGHT: (C)2007,JPO&INPIT |
