Abstract:
A lens driving module includes a holder, a cover, a carrier, at least one first magnet, a first coil, at least two second magnets, at least one first sensor and at least one second sensor. The holder includes an opening hole. The cover is made of metal material and coupled to the holder. The carrier is movably disposed in the cover and for coupling to a lens. The first magnet is movably disposed in the cover. The first coil is wound around an outer side of the carrier. The second magnets are disposed on one end of the carrier. The first sensor is for detecting a magnetic field of the second magnets. The second sensor is for detecting a magnetic field of the first magnet.
