Abstract

Systems and methods for providing haptic feedback at multiple resonance frequencies are disclosed. For example, one disclosed apparatus includes a resonator with a base and a plurality of projections, a first projection of the plurality of projections having a first resonance frequency and a second projection of the plurality of projections having a second resonance 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.

[0003] The present invention relates generally to haptic feedback, and more particularly to systems and methods for providing haptic feedback at multiple resonant frequencies. Background technique

[0004] A haptic feedback system vibrating at its resonant frequency may provide several advantages, including enhanced haptic feedback effects and / or more efficient power usage. Conventional haptic feedback systems may utilize multiple actuators each outputting vibration at a different resonant frequency to implement a system with multiple resonant frequencies. However, using multiple actua...
