の範囲第１項に記載の圧電音響変換装置。[Claims for Utility Model Registration] (1) A piezoelectric vibrator in which a small-diameter piezoelectric element is bonded to the center of the back surface of a large-diameter metal plate is placed inside a case with a sound hole formed in the center of the metal plate. is arranged so as to face the sound hole, the circumferential surface of the metal plate is supported by the circumferential portion inside the case over the entire circumference, and the ring is provided with conductivity on the back side of the circumferential portion of the metal plate. A piezoelectric acoustic transducer is constructed by arranging a shaped spacer, and further arranging an insulating substrate with a pair of terminals on the outside of this spacer, and electrically connecting one terminal to the piezoelectric element and the other terminal to the spacer. The piezoelectric acoustic transducer is a piezoelectric acoustic transducer in which the spacer is made of an elastic material having electrical conductivity and is formed into a one-turn spiral shape separated at one point in the circumferential direction. (2) The piezoelectric acoustic transducer according to claim 1, wherein the spacer is formed by winding a metal wire having a rectangular cross section.
