Abstract
A camera lens drive mechanism includes a lens cylinder, and the lens hollow is able to fit over a lens. A conductor coil is wound around an outer surface of the lens cylinder, and a coil spring is surrounding the lens hollow cylinder. A magnetic body is opposite to the conductor coil for the magnetic line of force from the magnet can cut across the conductor coil. An active force is induced on the coil when a current is conducted in the conductor coil, and then the lens cylinder is pushed also. The magnitude of the active force can be controlled by adjusting the magnitude of the current in the conductor coil.
