Title: DRIVE DEVICE, ELECTRONIC APPARATUS, AND DRIVE CONTROL PROGRAM
Abstract:
The problem addressed by the present invention is to provide: a drive device that can provide a tactile sensation that is in accordance with operation; an electronic apparatus; and a drive control program. The drive device has: a storage unit that stores waveform data that is of a drive signal that vibrates an actuator (m/2)×a times (where a is a natural number other than 0) and that is a sine wave satisfying a frequency of f1 = (m/n)×f0 (where m and n are positive odd numbers that are different from each other) where f0 is the resonance frequency of the actuator; and a drive processing unit that reads the waveform data stored in the storage unit and outputs to the actuator a drive signal corresponding to the waveform data.
