【発明の名称】ダイアフラムを備えた電気音響変換器及びダイアフラムを電気音響変換器に取り付ける方法
Document Type and Number:
Japanese Patent JP2002541749
Kind Code:
A
Abstract:
An electroacoustic transducer employing a polymer connection for maximizing volume displacement. The transducer includes a diaphragm in a case and means for converting. The diaphragm includes a central portion. The means for converting converts between an electric signal and a vibration of the central portion of the diaphragm or vice versa while the diaphragm is coupled to the case. The central diaphragm has an outer edge, and between the outer edge and the inner wall of the transducer case a capillary space is present in which a polymer is provided as a coupling between the outer edge and the inner wall of the case.
