Abstract
An actuator module for optical image stabilization of a lens assembly relative to an image sensor in a camera includes a coil mounting structure. A plurality of optical image stabilization (OIS) coils is mounted to the coil mounting structure. Some embodiments include a lens assembly structure configured to hold a lens assembly. A plurality of magnets is affixed to the lens assembly structure. Some embodiments include a spring assembly for coupling the coil mounting structure to the lens assembly structure, such that the lens assembly structure is movable relative to the coil mounting structure in a plane orthogonal to an optical axis of the lens assembly. The lens assembly comprises a light input side and an opposing light exit side for providing light for an image to an image sensor. The plurality of OIS coils is mounted closer to the light input side than the plurality of magnets.
