PIEZOELECTRIC VIBRATION GENERATOR AND VIBRATORY SOUND TRANSMITTER

摘要

A piezoelectric vibration generator capable of providing a sufficiently large vibration by supporting a piezoelectric vibrator at one point near the center thereof and freely vibrating the end part thereof, comprising a piezoelectric vibrator (12) to which input signals are applied, a diaphragm (11) to which vibration from the piezoelectric vibrator is transmitted, and a connecting means (13) having one end fixed to near the center of the piezoelectric vibrator (12) and the other end fixedly connected to the diaphragm (11), wherein the connecting means (13) is supported by a vibration damping film (21) and generally transmits the vibration of the piezoelectric vibrator to the diaphragm through the connecting means.
