Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electroacoustic transducer capable of improving a pitch extent from a middle-frequency range to a high-frequency one, and to provide a diaphragm. SOLUTION: The diaphragm 11 comprises a central vibration section 19 in a dome-like section, and a periphery vibration section 21 that is arranged at the periphery of the central vibration section 19 integrally and continuously, and has an edge section 21b fixed to a frame 13 for support and has a dome-like section. The diaphragm 11 is formed in a combined shape of a thick board thickness region D and a thinner board thickness region D-1 than the thick one D. The thin board thickness region D-1 is set to be the edge section 21b of the periphery vibration section 21. COPYRIGHT: (C)2008,JPO&INPIT
