Abstract
A camera module includes a lens unit, a magnet, a stator and an elastic element. The stator includes an upper coil seat with an upper coil wound therearound and a lower coil seat with a lower coil wound therearound. The upper and the lower coils establish an induced magnetic field when electric currents are applied thereto. The induced magnetic field interacts with the magnet to generate a magnetic force driving the lens unit into a telescopic movement. The elastic element includes a plurality of ribs. Each rib includes a fixed end connected with the stator and an opposite movable end. The moveable end moves together with the lens unit with respect to the fixed end to cause the ribs to deform and generate an elastic force. The lens unit stops at a focal position when the magnetic force and the elastic force come to a balance.
