Abstract

PURPOSE:To improve the pulse response characteristic, by providing a vibration diaphragm in the center of a stuck piezoelectric vibrator and by fixing peripheral parts of the diaphragm and the stuck piezoelectric vibrator to a case by a buffer material. CONSTITUTION:A vibration diaphragm 13 is provided on a coupling shaft 12 provided in the center of a stuck piezoelectric element consisting of piezoelectric ceramic, and peripheral parts of the diaphragm 13 and the stuck piezoelectric element 11 are fixed elastically to the inside face of a cylindrical case 17 by a buffer material 20 consisting of an elastic rubber or the like and are supported for the purpose of suppressing mechanical vibration. Terminals 16 and 16' are connected to the stuck piezoelectric element 11 by lead wires 19 and 19'.
