Patent abstract
A voice coil motor includes a case, a stationary module, and a movable module. The stationary module is retained within the case, and includes a housing and a number of magnets. The housing and the plurality of magnets are integrally formed. The movable module is movably retained within the case, and includes a barrel and a coil coupled to the barrel. When electric current is applied to the coil, the coil generates a magnetic field and the magnetic field repels the magnets, thereby driving the movable module to move.
