<p>In a piezoelectric electroacoustic transducing device which is to be incorporated in an electronic apparatus such as a portable telephone, and which is used as a sound source, the sound pressure of the low-frequency range is improved, the productivity is improved, and acoustic characteristics are stabilized. A piezoelectric electroacoustic transducing device 10 has: a frame 15; a piezoelectric vibrator 11 in which piezoelectric elements 12A, 12B are bonded to a metal plate 13; and a plate- and ring-like support member 14 which supports a peripheral portion of the piezoelectric vibrator 11 on the frame 15. A step 14C corresponding to the thickness of the metal plate 13 is disposed in the support member 14 , and the metal plate 13 is adhered to the inside of the step 14C in an embedded manner.
