PIEZOELECTRIC VIBRATION MODULE AND VIBRATION GENERATING APPARATUS INCLUDING THE SAME |
摘要 |
There are provided a piezoelectric vibration module and a vibration generating apparatus including the same. The piezoelectric vibration module includes: a piezoelectric actuator including a piezoelectric element deformed in both a first direction and a second direction perpendicular to the first direction through the application of electrical power thereto; at least one first rod transferring deformation force of the piezoelectric actuator in the first direction; at least one second rod converting deformation force of the piezoelectric actuator in the second direction into deformation force in the first direction and transferring the converted deformation force; and a mass body connected to the first and second rods and disposed on the piezoelectric actuator so that displacement is generated in the first direction. |
