Abstract
There is provided a vibration generating apparatus including a vibration transferring member transferring vibrations to outside the vibration generating apparatus, an elastic member having one or more end portions fixed to the vibration transferring member, a mass body vibrating in response to vibrations of the elastic member, and a piezoelectric element installed on one surface of the elastic member so as to be disposed to face the mass body. A lower surface of the mass body has step parts in order to prevent contact between the mass body and the piezoelectric element. The lower surface of the mass body in which the step parts are formed and the piezoelectric element are disposed so as to be spaced apart from each other by a predetermined distance.
