Patent abstract
A haptic device can be realized with a single acoustic actuator controlling multiple unit cells by having the unit cells be composed of cantilever arms with different resonant frequencies. The unit cells can be further improved by having the cantilever arms be in a spiral shape, and more specifically an Archimedes spiral shape.
