を特徴とする圧電音響変換装置。 A piezoelectric vibrator is constructed by overlapping a metal diaphragm and a piezoelectric element formed with a smaller diameter than this, and the piezoelectric vibrator is placed inside the case with the electrode surface of the piezoelectric element facing the opening side of the case. the opening of the case is closed with an insulating cover, with air chambers provided on both sides of the piezoelectric vibrator, and the diaphragm is directed toward the case opening side of the diaphragm. In a piezoelectric acoustic exchange device in which external terminals electrically connected to one surface and an electrode surface of the piezoelectric element are pulled out to the outside of the insulating cover, the external terminals connected to one surface of the diaphragm are connected to the metal wires of the case. A loop-shaped terminal consisting of a loop part that goes around the step part almost once, and a lead-out part drawn out from the winding end of this loop part almost perpendicularly to the virtual plane formed by the loop part. A piezoelectric acoustic transducer characterized in that the loop portion of the loop-shaped terminal is crimped and clamped between the diaphragm and the insulating cover.
