Abstract
Disclosed herein is a piezoelectric actuator module. The piezoelectric actuator module includes a flat plate. An elastic member is provided on each of opposite ends of the plate in a longitudinal direction thereof, and protrudes perpendicularly from the plate in such a way that a first end of the elastic member is coupled to an electronic device. A plate-shaped elastic body is provided on a first surface of the plate. A piezoelectric element is provided on a first surface of the elastic body. The plate-shaped elastic body is provided between the plate and the piezoelectric element, so that the overall spring constant of the piezoelectric actuator module is lowered and thus the vibrating force of the piezoelectric actuator module is increased.
