Abstract
Embodiments of the invention provide a piezoelectric vibration module, including a vibration plate mounted with a piezoelectric element, which generates a vibration force in a vertical direction by being repeatedly expanded and contracted depending on external power applied thereto, and a lower case coupled with both ends of the vibration plate so as to be spaced apart from the vibration plate. The piezoelectric vibration module further includes a bar-shaped weight body increasing the vibration force of the piezoelectric element, and an elastic member interposed between the vibration plate and the weight body.
