DRIVING DEVICE HAVING THE PIEZOELECTRIC ELEMENT

摘要

PURPOSE: By runing the lens holder installed inside the camera device to the upward and downward by practicing operation of the weight of the lens holder, the driver in which the piezoelectric element installs transfers the lens. CONSTITUTION: The driver(30) is proceed the role of runing the lens holder to the optical axial, in other words, upward and downward. It is composed of the driver resonant cavity(31) and piezoelectric element(39), one end of the resonant cavity is specifically combined the base member(10) in the fixed axis.
