Problems solved by technology

These types of haptic actuators deliver crimp performance, but the transducers typically consist of ceramics and are fragile
A sharp impact from dropping or hitting something often causes the transducer to break, which prevents the haptic actuator from working and delivering haptic effects

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.

Description

technical field [0001] This patent document relates generally to haptic actuators, and more specifically to inertial haptic actuators with cantilever beams and smart materials. Background technique [0002] Linear resonant haptic actuators are used in a variety of applications including many different types of portable electronic devices. These actuators are typically piezoelectric flexures, which are suspended beams with layers formed from piezoelectric transducers. Applying a voltage to the piezoelectric transducer causes the transducer to vibrate, which in turn vibrates the beam to deliver the haptic effect. These types of haptic actuators deliver crimping properties, but the transducers typically include ceramic and are fragile. A sharp impact from dropping or hitting something often causes the transducer to rupture, which makes the haptic actuator incapable of working and delivering haptic effects. SUMMARY OF THE INVENTION [0003] One aspect of this patent documen...
