Abstract: According to some embodiments, a haptic feedback module for generating a haptic feedback event is described. The haptic feedback module includes an enclosure having walls that define a cavity. The enclosure is capable of carrying operational components within the cavity that include a frame that includes tungsten, a magnetic coil element that is capable of generating a magnetic field, a magnetic element that is carried within an aperture of the frame, linear-actuation end stops that are welded to a first end of the frame and a second end of the frame that opposes the first end, and springs that couple together the walls of the enclosure to the linear-actuation end stops.

Abstract: A haptic actuator may include a housing that includes a ferromagnetic material having a first heat conductance, and a coil carried by the housing in a medial portion thereof and generating waste heat when electrically powered. The haptic actuator may also include a field member movable within the housing responsive to the coil. The field member may include at least one permanent magnet establishing a magnetic path with the housing. A heat spreading layer may be thermally coupled to the housing adjacent the coil. The heat spreading layer may have a second heat conductance greater than the first heat conductance to spread the waste heat from the coil to adjacent portions of the housing.
