Lens actuating module

摘要

A lens actuating module includes a holder, a cover, a lens and a lens actuator. The holder includes an opening hole and at least three first connecting portions. The cover is coupled to the holder and includes a through hole correspondent to the opening hole. The lens with an optical axis is correspondent to the through hole. The lens actuator is movably disposed in the cover and includes at least one elastic member and at least three suspension wires. The elastic member includes at least three second connecting portions. A longitudinal direction of each of the suspension wires is parallel to the optical axis. Two ends of each of the suspension wires are fixedly connected with one of the first connecting portions and one of the second connecting portions, respectively. More than 95% of each of the suspension wires along the longitudinal direction has a rectangular cross-section.
