Abstract
A system for amplifying haptic effects provided by a push-pull actuator includes a housing component, a push-pull actuator coupled to the housing component and configured to provide a force and a displacement, a lever component including a lever arm and a fulcrum, and a haptic touch surface coupled to the lever arm via an output interface. The push-pull actuator is via an actuator mount. The amount of displacement transferred to the haptic touch surface from the push-pull actuator is reduced by the lever component and the amount of force transferred to the haptic touch surface from the push-pull actuator is increased by the lever component. The system may include a material stop coupled to the housing component that when compressed by the haptic touch surface exhibits hysteresis to dampen the haptic touch surface.
