Abstract: A haptic actuator may include a housing, a coil carried by the housing, and a field member movable within the housing responsive to the coil. The field member may include a frame having opposing first and second ends, at least one magnet carried by the frame, and a first overmolded endcap coupled to the first end of the frame. The field member may also include a second overmolded endcap coupled to the second end of the frame. The haptic actuator may include a first flexure having an inner end coupled to the first overmolded endcap, and an outer end coupled to adjacent portions of the housing. The haptic actuator may also include a second flexure having an inner end coupled to the second overmolded endcap, and an outer end coupled to adjacent portions of the housing.

Abstract: A haptic actuator may include a housing that includes first and second shells. The first shell may define a first tab and the second shell may define a second tab. The housing may also include a plastic end portion positioned between the first and second shells. The plastic end portion may define recesses that receive the first and second tabs. At least one coil may be carried by the housing. A field member may be movable within the housing responsive to the at least one coil. A flexure may be coupled to the plastic end portion and the field member.

Abstract: An electronic device includes a housing. The housing includes a first plate defining a first wall; a cover defining a second wall opposite the first wall, a first sidewall, and a second sidewall opposite the first sidewall; and a second plate and a third plate, respectively defining a third sidewall, and a fourth sidewall opposite the third sidewall. The first, second, third, and fourth sidewalls extend between the first wall and the second wall. The electronic device further includes a movable mass disposed within the first, second, third, and fourth sidewalls of the housing; a first spring and a second spring, respectively attached to first and second opposite ends of the movable mass; and a first material and a second material, respectively joining the first spring to the second plate and the second spring to the third plate.

Abstract: A haptic actuator includes a housing having a ferromagnetic wall. The ferromagnetic wall has a set of one or more half shear ferromagnetic features protruding from the ferromagnetic wall into the housing. A movable magnet is positioned within the housing. A pair of springs, respectively attached to opposite sides of the housing and opposite ends of the movable magnet, bias the movable magnet toward a position of rest between the pair of springs. An electric coil is attached to the set of one or more half shear ferromagnetic features and positioned between the movable magnet and the set of one or more half shear ferromagnetic features.

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: Systems, methods, and apparatuses described herein correspond to non-linear spring assemblies of a haptic engine. An enclosure and/or lid of a haptics engine may include a number of non-linear spring assemblies to dampen or reduce peak forces between internal components of the haptics engine and the enclosure and/or the lid. By dampening or reducing peak forces, damage to internal components of the haptic engine and/or an associated electronic device may be reduced or eliminated.

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.
