Abstract: A lens driving device is provided, including a base, a holder, a first driving mechanism disposed on the first side of the base, a second driving mechanism disposed on the second side of the base opposite the first side, and a conductive member disposed on the base. The holder is configured to sustain a lens. The first driving mechanism is configured to force the holder to move along the optical axis of the lens. The second driving mechanism includes a circuit board assembly and a shape memory alloy (SMA) wire assembly configured to force the base to move in the plane perpendicular to the optical axis. The conductive member and the circuit board assembly are connected at an electrical connection point, and the SMA wire assembly is closer to the light-incident end of the lens with respect to the electrical connection point.

Abstract: An electromagnetic driving device is provided, which includes a stationary portion, a movable portion adapted to support an element, a number of rolling balls, a driving magnet, a driving coil, and a magnetic attraction element. The stationary portion and the movable portion are arranged along a main axis. The rolling balls and the driving magnet are positioned between the stationary portion and the movable portion. The driving coil is arranged to correspond to the driving magnet and configured to enable the movement of the movable portion along a direction perpendicular to the main axis. The magnetic attraction element is arranged to correspond to the driving magnet. The magnetic force between the magnetic attraction element and the driving magnet is greater than the sum of the weight of the movable portion, the element, and the magnetic member.
