SYSTEM, APPARATUS AND METHOD FOR HAPTIC COMMANDS
First Claim
1. A system, 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 thatapplies a first driving voltage to the haptic actuator in response to the first haptic command, andapplies a second driving voltage larger than the first driving voltage to the haptic actuator in response to the second haptic command;
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.

8. An electronic apparatus, comprising:
-
a haptic actuator that operates in a vibration mode and an impact mode; a DC power supply; a first power supply circuit that outputs an output voltage from the DC power supply as a first DC voltage; a second power supply circuit, comprising a booster that steps up an output voltage to a second DC voltage higher than the first DC voltage; a drive circuit that applies, to the haptic actuator, a first driving voltage generated from the first DC voltage in the vibration mode, and applies, to the haptic actuator, a second driving voltage generated from the second DC voltage in the impact mode; and a controller that designates an operating mode of the haptic actuator to the drive circuit. - View Dependent Claims (9, 10, 11, 12, 13, 14)
