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: 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.
