Title: PACKAGE-INTEGRATED HYBRID HAPTIC ACTUATORS
Abstract:
A hybrid haptic actuator includes a package-integrated piezoelectric haptic actuator and a package-integrated electromagnetic haptic actuator disposed in, on, or about a void space formed in a first surface of a dielectric substrate. The hybrid haptic actuator includes an elastomeric member that covers the hybrid haptic actuator and a magnetic member embedded in the elastomeric member that is displaced by the magnetic fields produced by the electromagnetic haptic actuator. In operation, the magnetic member may be displaced from a neutral position to a first position by applying a voltage to the piezoelectric haptic actuator. The magnetic member may be oscillated at a frequency by applying an alternating current at the frequency to the electromagnetic haptic actuator. Such a hybrid haptic actuator beneficially consumes about half the power of a single haptic actuator having an equal displacement.
