Abstract: A haptic actuator may include a housing that includes first and second shells coupled together. The first shell may include a first body and first terminals extending outwardly therefrom. The second shell may include a second body and second terminals extending outwardly therefrom with each of the second terminals being secured with a respective one of the first terminals defining pairs of first and second secured-together terminals. The haptic actuator may also include at least one coil carried by the housing and a field member movable within the housing responsive to the at least one coil. A respective flexure may be between adjacent end portions of the housing and the field member.

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.
