A piezoelectric vibrator is disclosed. A piezoelectric vibration member vibrates according to the change of polarity of applied voltage while the edge portions or a central portion shows maximum displacement with the central portion or the edge portions as an acting point of vibration, respectively. Being combined integrally with the portion of maximum displacement of the piezoelectric vibration member by a fastening member, a weight vibrates together with the vibration of the piezoelectric vibration member and amplifies the vibration. A vibration support member has one end fixed to the object to transfer vibration to and the other end combined to a specific portion of the piezoelectric vibration member, supporting the piezoelectric vibration member so as to vibrate up and down with the specific portion as an acting point of vibration. |
