VIBRATION GENERATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a vibration generating apparatus.SOLUTION: There is provided a vibration generating apparatus including: a vibration transferring member having an internal space; an elastic member, both end portions of which are fixed to the vibration transferring member; a weight body coupled with the elastic member; and a piezoelectric element mounted on one surface of the elastic member so as to face the weight body. A bottom surface of the weight body has step parts formed to prevent contact between the weight body and the piezoelectric element. The bottom surface of the weight body in which the step parts are formed and the piezoelectric element are separated by a predetermined distance.
