Abstract: A lens driving apparatus is for driving a lens assembly and includes a base, a metal cover, a carrier, a first coil, at least one first magnet, at least one second magnet, a frame and a spring set. At least one lower leaf spring of the spring set includes a frame connecting section, a carrier connecting section and a resilient section. The carrier connecting section and the second magnet are arranged along the first direction. The carrier connecting section includes an opening portion and a shielding portion, and the opening portion and the shielding portion both corresponding to the second magnet along the first direction are respectively for a part of the second magnet to be exposed through the opening portion and another part of the second magnet to be shielded by the shielding portion.

Abstract: A dual lens driving apparatus includes a holder, a metal yoke, a carrier, a coil, a first magnet, a first elastic element and a second elastic element. The metal yoke is corresponding to the holder and includes a front end which includes a plate surface and a plurality of step portions, and a level difference is between each of the step portions and the plate surface. The carrier is movably disposed in the metal yoke. The coil is disposed around the carrier. The first magnet is disposed in the metal yoke. The first elastic element is assembled on a side of the carrier facing the front end of the metal yoke. The second elastic element is assembled on another side of the carrier facing the holder.
