A voice coil motor for driving a lens group includes a housing, a first cover, a second cover, a movable member, and a plurality of magnets. The housing is a hollow and includes a top plate and four sidewalls protruding from the top plate. The movable member is movably received in a space defined by the housing and the first and second covers, and includes a barrel for receiving and being connected to the lens group, and a coil arranged around the barrel. The magnets are arranged between the housing and the movable member, stayed in contact with the sidewalls, and drive the movable member and the lens group to move in the housing when a current is supplied to the coil.
