Abstract: Various embodiments disclosed herein include mechanical iris assemblies, as well as camera modules and devices that incorporate these mechanical iris assemblies. The mechanical iris assemblies described herein include a housing, a rotor plate, a set of blade elements, and an actuator arrangement. The actuator assembly may include a voice coil actuator. In some variations, a voice coil actuator includes a magnet, a first coil, and a second coil, and a controller is configured to concurrently drive current through the first coil and the second coil in opposite directions. In other variations, a voice coil actuator includes at least one magnet and a set of arcuate-shaped coils. In still other variations, a voice coil actuator includes at least one magnet and a printed circuit that defines a coil that includes an inner trace, an outer trace, and a set of connecting traces that connect the inner trace to the outer trace.
