ABSTRACT:
An exemplary lens module includes a barrel, a lens received in the barrel, a movable coil unit, and a magnet. The movable coil unit includes a first coil and a plurality of resilient elements. The first coil is wound around a peripheral sidewall of the lens in a first winding direction. The first coil is mounted in the barrel. A first end of each of the resilient elements is connected to the first coil, and a second end of each of the resilient elements is mounted to an inner surface of the barrel. The first coil is movable along the optical axis, thus driving the lens to move along the optical axis. The magnet is received in the barrel and faces the first coil.
