Abstract
A camera module includes a lens unit, a magnet mounted around the lens unit, a stator receiving the lens unit and the magnet therein and an elastic element. The stator includes a coil seat and a coil wound therearound. The coil establishes a magnetic field when an electric current is applied thereto. The magnetic field interacts with a magnetic field of the magnet to generate a magnetic force driving the lens unit into telescopic movement. The elastic element includes at least one rib which has 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 generate an elastic force during the telescopic movement of the lens unit. The lens unit stops at a focal position when the magnetic force and the elastic force come to a balance.
