A haptic actuator may include a housing, and a stator fixed to a medial interior portion of the housing. The haptic actuator may also include a field member having an opening receiving the stator therein. The field member may include a frame and at least one permanent magnet carried by the frame. The haptic actuator may also include at least one flexure coupled between an end of the frame and adjacent interior portions of the housing to permit reciprocal movement of the field member within the housing responsive to the stator.

A haptic actuator may include a housing, a stator coupled to a medial interior portion of the housing, and a field member within the housing and having an opening receiving the stator therein. The field member may include a frame, and at least one permanent magnet carried by the frame. The at least one permanent magnet may include side-by-side magnetic segments having alternating magnetic polarizations with at least one non-vertical magnetic polarization transition zone between adjacent magnetic segments.

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.
