CAMERA ACTUATOR USING THE PIEZOELECTRIC ELEMENT

摘要

PURPOSE: A camera actuator using the piezoelectric element is provided to transfer a lens by driving a lens holder up and down using a piezoelectric element. CONSTITUTION: A lens holder(110) has a lens and is driven along an optical axis direction. A first piezoelectric element(120) protects the circumferential surface of the lens holder, and has a hollow circular shape. A second piezoelectric element(130) protects the outer circumference of the lens holder, and has a fixed hollow shape. The first piezoelectric element and the second piezoelectric element are arranged in a driving direction of the lens holder.
