Application Number: JP,2025-123347
Category (FI): H04R1/10,101@Z,H04R19/02,H04R1/10,104@Z
Stage: PROBLEM TO BE SOLVED: To provide an electroacoustic transducer in which a vibrating membrane is less likely to be broken and sound pressure is improved even when the transducer is small.SOLUTION: An electroacoustic transducer 2 includes a housing 20, a partition member 30 disposed inside the housing 20, a first electroacoustic conversion unit 100, and a second electroacoustic conversion unit 200. The electroacoustic conversion unit of the first (2) includes a fixed electrode 101 (201), a vibrating film 105 (205) which is disposed to face the fixed electrode and vibrates according to a potential difference generated between the fixed electrode and the fixed electrode based on an electric signal, and a support member 107(207) which supports a partial region of the vibrating film and brings a part of the vibrating film into contact with the fixed electrode. The first electroacoustic conversion unit and the second electroacoustic conversion unit are disposed to face each other with a partition member 30 interposed therebetween so that a sound emitting part 100a and a sound emitting part 200a communicate with an acoustic outlet 2a, and the partition member 30 supports the support member 107 and the support member 207.SELECTED DRAWING: Figure 3 (Grant)
