Abstract: An actuator assembly comprising: a multi-layer board comprising a first side and a second side defining an actuation region having a thickness that is reduced relative to a remainder of the multi-layer board; a planar voice coil formed by a trace on at least one of the first side or the second side defining the actuation region; and a polarized magnet array having a magnetic field aligned to the planar voice coil to actuate the actuation region upon application of a voltage to the planar voice coil.
