Abstract

A voice coil actuator assembly includes a housing assembly, a magnet assembly, a bobbin, and a plurality of coils. The magnet assembly is disposed within, and is movable relative to, the housing assembly and includes a plurality of permanent magnets. The bobbin is fixedly mounted within the housing assembly and surrounds the magnet assembly. The bobbin includes a plurality of winding cavities. Each winding cavity is at least partially coated with a dielectric coating material and has a bottom surface and two side walls. The coils are electrically connected in series. Each coil is wound on the bobbin and is disposed, one each, within a different one of the winding cavities. Each coil comprises magnet wire coated with the dielectric coating material. When the coils are electrically energized, a linear force is generated that causes relative motion between the magnet assembly and the housing assembly.
