Abstract
There are provided a vibration generating apparatus and an electronic apparatus including the same. The vibration generating apparatus includes: a housing having an internal space; an elastic member having both ends fixed to the housing so as to be elastically deformably disposed in the internal space; and a piezoelectric element mounted on one surface of the elastic member, wherein power is supplied to the piezoelectric element so that warpage of the piezoelectric element is only generated toward any one of one surface of the elastic member and the other surface of the elastic member, a surface opposite to the one surface of the elastic member.
