Micro piezoelectric linear motor of beam type and camera module

摘要

The present invention improves the driving performance in a piezoelectric linear motor in which a piezoelectric plate is attached to an elastic body, and a moving shaft is attached to the piezoelectric plate and the elastic body to vibrate linearly with the movable body mounted on the moving shaft as the piezoelectric plate and the elastic body are displaced by the piezoelectric effect. It relates to a camera module in which the integrated linear motor and the piezoelectric linear motor are integrally installed.;Piezoelectric Effect, Elastic Body, Linear Motor, Stiffness Coefficient
