Abstract

See full text

A haptic actuator assembly includes a haptic actuator configured to output displacement along a perpendicular axis and a pre-load device. The pre-load device is disposed adjacent to the haptic actuator and configured to generate a compressive load on the haptic actuator along the perpendicular axis to oppose expansion of the haptic actuator along the perpendicular axis. The haptic actuator is disposed within an enclosed cavity formed by a casing. A pressure within the enclosed cavity is varied in order to create the compressive load on the haptic actuator along the perpendicular axis. The pre-load device may alternatively be a connector component formed from a shrinkable material that is configured to longitudinally shrink to exert a force in order to create the compressive load on the haptic actuator along the perpendicular axis.
