Abstract
In some embodiments, a camera actuator includes an actuator base, an autofocus voice coil motor, and an optical image stabilization voice coil motor. In some embodiments, the autofocus voice coil motor includes a lens carrier mounting attachment moveably mounted to the actuator base, a plurality of shared magnets mounted to the base, and an autofocus coil fixedly mounted to the lens carrier mounting attachment for producing forces for moving a lens carrier in a direction of an optical axis of one or more lenses of the lens carrier. In some embodiments, the optical image stabilization voice coil motor includes an image sensor carrier moveably mounted to the actuator base, and optical image stabilization coils moveably mounted to the image sensor carrier within the magnetic fields of the shared magnets, for producing forces for moving the image sensor carrier in a plurality of directions orthogonal to the optical axis.
