Disclosed is a vibration generation device. The vibration generation device includes a housing having an internal space, a vibration member which includes first and second vibration members which are fixed to both ends of the housing, first and second piezoelectric parts which are installed in the first and second vibration members, a weight body case which is connected to the upper surface of the vibration member, and a weight body which is connected to the vibration member and vibrates by interlocking with the vibration member. So, the generation of a distortion mode can be reduced. |
