A drive apparatus includes a memory to store waveform data representing a sinusoidal drive signal satisfying a frequency f1=(m/n)×q(t) (m and n: natural numbers, m≠n), to vibrate a vibration-generating device m times, where q(t) is a time characteristic of a resonance frequency of the vibration-generating device, or ((m/2)×r) times (r: natural number≠0, m and n: positive odd, m≠n), the vibration-generating device having the resonance frequency varying depending on an acceleration amplitude in a range between first and second resonance frequencies including the rated value f0; and a drive-processor to output the drive signal to the vibration-generating device. The q(t) is obtained when driving the vibration-generating device by a sinusoidal drive signal satisfying f1=(m/n)×f2, to vibrate the vibration-generating device m times if m≠n, or ((m/2)×r) times.
