First Claim
1. A system for generating haptic effects, comprising:
- a command module that generates a first haptic command and a second haptic command;
a haptic actuator that vibrates with a magnitude varying in accordance with a magnitude of a driving voltage; and
a drive circuit comprising a first power supply circuit comprising a first booster, and a second power supply circuit comprising a second booster thatapplies a first driving voltage from the first power supply circuit and the first booster to the haptic actuator in response to the first haptic command,applies a second driving voltage larger than the first driving voltage from the second power supply circuit and the second booster to the haptic actuator in response to the second haptic command, andsteps up the first driving voltage with the first booster in response to a decrease of the first driving voltage;
wherein a time for which the second driving voltage is applied is shorter than a time for which the first driving voltage is applied.

Abstract
A system, apparatus and method are disclosed. The system includes a command module that generates haptic commands; a haptic actuator; a drive circuit that applies a first driving voltage in response to a first haptic command and applies a second driving voltage in response to a second haptic command. The apparatus includes a haptic actuator; a DC power supply; a first power supply circuit that outputs a first DC voltage; a second power supply circuit that outputs a second DC voltage higher than the first DC voltage; a drive circuit that applies a first driving voltage and a second driving voltage; and a controller that designates an operating mode. The method includes generating a first haptic command and a second haptic command; applying a first driving voltage to a haptic actuator; and applying a second driving voltage to the haptic actuator.
