Abstract
Disclosed herein is a piezoelectric vibration module including: a piezoelectric element repeatedly extended and compressed according to application of external power to generate vibration force; a vibration plate having the piezoelectric element coupled to one surface thereof and repeatedly extended and compressed integrally with the piezoelectric element to transfer the vibration force of the piezoelectric element to an external component; a weight body having a central portion coupled to the other side of the vibration plate in order to increase the vibration force of the piezoelectric element; and a coupling member fixedly coupling the central portion of the weight body and the vibration plate to each other.
