Abstract

A haptic actuator comprising a base and a haptic transducer at least partially suspended by the base. The haptic transducer comprises a substrate and a smart material operably connected to the substrate. The smart material has resonance in response to an electrical signal having a determined frequency, and the resonance causes the haptic transducer to vibrate and deliver a haptic effect.

Claims

1. A haptic actuator comprising:

a base; and

a haptic transducer at least partially suspended by the base, the haptic transducer having a substrate and a smart material component supported by the substrate;

the smart material component having smart material, the smart material being encapsulated; and

the haptic transducer having resonance in response to an electrical signal having a determined frequency, the resonance causing the haptic transducer to vibrate and deliver a haptic effect.
