| 摘要 | A driving device includes a storage unit configured to store waveform data of driving signals whose phase is shifted by π/2 from a sinusoidal wave satisfying a frequency f1=m/n×f0 (m, n are natural numbers, and m≠n) where a resonance frequency of an actuator is f0, wherein the driving signals excite the actuator for an m number of times and stop exciting the actuator at a point other than a center point of amplitude; and a processor programmed to execute a process including reading the waveform data stored in the storage unit and outputting, to the actuator, the driving signals corresponding to the waveform data that has been read. | ||
