摘要：Disclosed herein is a piezoelectric vibration module including: a piezoelectricelement repeatedly extended and compressed according to application of externalpower to generate vibration force; a vibration plate having the piezoelectric elementcoupled to one surface thereof and repeatedly extended and compressed integrally with
the piezoelectric element to transfer the vibration force of the piezoelectric element toan external component; a weight body having a central portion coupled to the other sideof 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 bodyand the vibration plate to each other.
