发明名称 Voice coil type lens drive assembly
摘要 A lens drive assembly includes a pair of electrically conductive springs (2) disposed on the base (1), a metallic yoke (6) disposed on the electrically conductive springs (2), magnets (5) mounted within the yoke (6), a movable unit (M1) inserted into the yoke, a leaf spring (7) disposed on the yoke (6), and an upper cover frame (8) coupled to the base (1) while being superimposed on the leaf spring (7). The conductive springs (2) include spring body (2b), spring piece (2a) and a spring wire. The spring wire has U-turn curvilinear portions connected between the outer spring body (2b) and the spring piece (2a) in a sole plane. The leaf spring (7) has a spring frame (7a), a thin circular spring ring (7b), and a spring wire. The spring wire has U-turn curvilinear portions between the spring frame (7a) and the spring ring in a sole plane.
