Piezoelectric vibrator capable of amplifying self-vibration and electric/electronic appliance equipped with the same as vibrating means

摘要

PURPOSE: A piezoelectric vibrator is provided to increase the force and displacement of the device by forming a piezoelectric vibrating member and a weight to be one body. CONSTITUTION: A piezoelectric vibrator includes a piezoelectric vibrator member(12), a weight, a vibration supporting member(14), and a combining member(18). The piezoelectric vibrator member is changed according to applied voltage and generates vibration based on a point of vibration. The weight is combined with the piezoelectric vibrator member and is generated together with the piezoelectric vibrator member to change vibration force and displacement. The combining member combines the weight in the piezoelectric vibrator member to be one body.
