Abstract
A haptic output device including an actuator configured to generate a haptic effect, and a processor configured to communicate a driving signal to the actuator and to communicate a braking signal to the actuator before or at the same time the driving signal is terminated to generate the haptic effect. The braking signal has a frequency substantially the same as a resonant frequency of the actuator and at a reverse phase of the driving signal.
