CAMERA ACTUATOR USING THE PIEZOELECTRIC ELEMENT

摘要

PURPOSE: A small camera actuator using a piezoelectric element is provided to be solider than a VCM type and have a long moving distance of a lens holder. CONSTITUTION: A small camera actuator using a piezoelectric element includes a lens holder(20), the first and second piezoelectric elements(40,50), and a movable member(30). The lens holder is built in a housing. A lens is installed in the lens holder so that the lens holder is driven in an optical axial direction. The first and second piezoelectric elements are mounted in the housing. One end of the movable member is connected to the first piezoelectric element. The other end is connected to the second piezoelectric element. A driving unit(35) is formed on the center.
