Abstract
A lens driving apparatus includes a holder, a metal cover, a carrier, a sensing magnet, a printed circuit board, a position sensor, a coil and at least one driving magnet. The metal cover is coupled with the holder and has an opening. The carrier is assembled to a lens assembly having an optical axis, wherein the carrier is disposed in the metal cover and is movable along a direction parallel to the optical axis. The sensing magnet is coupled with the carrier. The printed circuit board is disposed near to one of the four lateral sides of the holder. The position sensor is disposed on the printed circuit board and corresponds to the sensing magnet. The coil is disposed on an outer surface of the carrier. One of the driving magnet is disposed in the metal cover and corresponds to the coil.
