Abstract
There is provided a vibration generating device including: a piezoelectric element which is deformed when power is applied thereto; an installation member below which the piezoelectric element is installed; a weight fixedly installed below the installation member to be disposed below the piezoelectric element; a plurality of elastic members connected to the installation member to change a displacement direction by deformation of the installation member and disposed to face each other; and a damper member fixedly installed on a lower surface of the weight, wherein a thickness of the damper member is determined to allow the damper member to be disposed in a space formed by the plurality of elastic members when the elastic members are driven normally.
