Abstract:
An actuator module includes a base plate extending in a plane, a voice coil connected to the base plate, and a magnet assembly that includes a back side facing the base plate and a front side facing away from the base plate. The magnet assembly includes a base layer and sidewalls defining a cup and an inner element including a center magnet mounted within the cup. The sidewalls include a first and second pair of sidewalls. The actuator module includes a rigid frame attached to the base plate, the rigid frame including four stubs. The actuator module also includes a plurality of springs suspending the magnet assembly relative to the frame and base plate, the plurality of springs including a first spring attached to the frame at a first pair of the four stubs and a second spring attached to the frame at a second pair of the four stubs.
