摘要： Electro-magnetic actuators used to provide a displacement of an optical element such as a lens carrier comprise at least one ferromagnetic frame associated with a large air gap and at least one ferromagnetic member parallel to and separated from an elongated section of a frame by a small air gap. Actuation causes a magnetic circuit that appears in the at least one frame, the at least one member and small air gaps and by-passes or bridges the large air gap. In some embodiments, the resultant magnetic force moves the at least one member and leads to the displacement of an optical element attached thereto. In some embodiments, at least one frame and at least one member are arranged to provide a center hole and are dimensioned to enable insertion of a lens carrier in the hole. In some embodiments, the displacement is for auto-focus. In other embodiments, the displacement is for optical image stabilization.

摘要： Provided are a lens driving motor and an elastic member of the lens driving motor. The elastic member of a lens driving motor, the elastic member includes a first spring and a second spring. The second spring is different from the first spring and disposed together with the first spring on one side of a carrier to support the carrier. A first lead line of a coil and a first external power source are connected to the first spring, and a second lead line of the coil and a second external power source are connected to the second spring to supply power to the coil. Since the carrier can be assembled to other part after a (+) lead line and a (−) lead line of the coil are connected to the first and second springs, respectively, using solder, a process is simple and convenient.
