Abstract
Some embodiments provide an actuator module for optical image stabilization of a lens assembly relative to an image sensor in a camera. In some embodiments, the actuator module includes a coil mounting structure. One or more optical image stabilization (OIS) coils is mounted to the coil mounting structure. The actuator module further includes a lens assembly structure configured to hold a lens assembly. One or more autofocus coils is affixed to the lens assembly structure. The actuator module further includes 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. The actuator module further includes a plurality of trapezoidal magnets affixed to the lens assembly structure for magnetic interaction with one or more of the one or more optical image stabilization coils and the one or more autofocus coils.
