PIEZO ACTUATOR ASSEMBLY AND OPTICAL SYSTEM WITH THE SAME

摘要

PURPOSE: A piezoelectric actuator assembly and an optical system with the same are provided to minimize changes of driving features due to assembling allowance. CONSTITUTION: A piezoelectric actuator assembly(100) includes a base board(10), an elastic board(20), a piezoelectric device(30), and a moving unit(40). A protrusion is formed on one side of the elastic board and is coupled with the base board. The piezoelectric device is arranged on the other side of the elastic board. If electricity is applied to the piezoelectric device, the piezoelectric device transfers vibration to the elastic board. One end of the moving unit is supported by the protrusion and the other end is coupled with the base board.
