摘要： A condenser microphone includes: a casing including a sound hole; a vibration film disposed in the casing so as to face the sound hole; a back plate disposed opposed to the vibration film; a spacer disposed between the vibration film and the back plate; and a hold member including a spring member. The back plate has an outer peripheral shape that is smaller than an inner peripheral shape of the casing so as to provide a clearance between an outer peripheral surface of the back plate and an inner peripheral surface of the casing. The back plate is held by the hold member from an opposite side of the vibration fills.

摘要： A microphone element having a diaphragm and a fixed electrode disposed opposite to each other on a silicon board having a central opening portion is mounted and fixed onto a base board having a sound hole. A perimeter-shaped side board and a cover board are mounted and fixed onto the board, thereby forming a back cavity on an upper side of the microphone element. The diaphragm and the fixed electrode are conducted to conductive layers of the cover board through conductive layers of the base board, and a conductive layer and a coiled spring in the side board respectively, and mounting on a surface of a printed board of an external apparatus can be carried out in a conductive layer on an upper surface thereof.

摘要： A circuit board forming member, a case forming member, a spacer forming member, a diaphragm sheet and a diaphragm plate forming member are laminated to form a portion, as excepting a back plate and a contact spring, of a condenser microphone, in plurality in a laminate. Moreover, the back plate and the contact spring are arranged in the air chamber, which is defined by the individual forming members, to form a plurality of condenser microphone constituents in the laminate. Next, the laminate is cut to separate the individual condenser microphone constituents thereby to manufacture the condenser microphones.
