SYSTEMS AND METHODS FOR PROVIDING HAPTIC FEEDBACK AT MULTIPLE RESONANCE FREQUENCIES

摘要

PROBLEM TO BE SOLVED: To provide systems and methods for providing haptic feedback at multiple resonance frequencies.SOLUTION: One disclosed apparatus includes: a resonator integrated with a base and a plurality of projections, where a first projection of the plurality of projections has a first resonance frequency and a second projection of the plurality of projections has a second frequency; and a piezoelectric actuator coupled to the resonator and operable to output a haptic feedback effect at the first resonance frequency and at the second resonance frequency.
