Abstract
In one embodiment of the present disclosure a haptic actuator is disclosed. The haptic actuator includes a housing, a movable mass, and a pivot assembly attaching the movable mass to the housing. The pivot assembly defines a pivot axis, and the movable mass has a mass center offset from the pivot axis along a lever arm extending perpendicular to the pivot axis. The haptic actuator includes a spring extending between the movable mass and the housing. The spring stores and releases energy received from movement of the movable mass. The spring prevents full rotation of the movable mass about the pivot axis. The haptic actuator includes an electric coil attached to the movable mass. The electric coil intersects the lever arm. The haptic actuator includes at least one magnet attached to the housing. The magnet is at least partially aligned with the electric coil. The movable mass moves with respect to the at least one magnet when a signal is applied to the coil.
