響変換器。[Claims for Utility Model Registration] Comprising a metal diaphragm on which piezoelectric ceramic elements having paired electrodes are attached on both sides, and a terminal plate disposed opposite to the metal diaphragm and having first and second terminals. In the piezoelectric electroacoustic transducer, a ring-shaped insulating film to which conductive first and second tongues are thermocompressed is bonded, and each of the first and second tongues is attached to the first and second conductive tongues. The metal diaphragm is interposed between the metal diaphragm and the terminal plate so as to be electrically connected to the terminal of The tip of the first tongue is soldered to the other electrode of the ceramic element through the hole, and the second tongue is bent so as to sandwich the insulating film, so that the tip is connected to the metal diaphragm. A piezoelectric electroacoustic transducer characterized by:
