A lens driving device, a camera module and an electronic device. The lens driving device includes a base, a metal shell, a carrier, a first coil, at least one first magnet, at least one second magnet, a frame and a shrapnel group. The carrier is movable at least along a first direction, the first direction being parallel to the central axis. The second magnet is fixed on the side of the carrier close to the base and moves with the carrier. The lower elastic piece of the elastic piece group is disposed on the side of the carrier close to the base and includes a frame connection area, a carrier connection area and an elastic area. The carrier connection area and the second magnet are arranged along the first direction, and the carrier connection area includes an opening part and a shielding part, both the opening part and the shielding part correspond to the second magnet along the first direction, so that a part of the second magnet passes through the opening part exposed and the other part is covered by the shielding part. Thereby, it is beneficial to improve production efficiency and maintain assembly accuracy. |
