Lens position adjustment using compressed optical image stabilization coils having bi-concave shape

Abstract:

Some embodiments of a camera unit of a multifunction device include an actuator for moving the optical package relative to the image sensor. In some embodiments, the actuator includes one or more lateral magnets situated at one or more sides of the optical package. In some embodiments, the actuator includes one or more optical image stabilization coils for circulating electric current in a plane perpendicular to the an optical axis of the optical package to generate magnetic interactions with a respective one of the one or more lateral magnets. In some embodiments, each of the optical image stabilization coils has an interior surface boundary, and a space enclosed by the interior surface boundary has a width smaller at a center of a length of the optical image stabilization coil than at the ends of the optical image stabilization coil.
