1. A vibration control system comprising:
a data receiver to receive eccentric motor drive data for an eccentric motor vibration device, the received eccentric motor drive data sampled at a first rate;
a vibration device having a resonance frequency that is higher than suitable for the eccentric motor vibration device and whose vibration amplitude and frequency are each controllable; and
a vibration data generator configured to generate vibration data for causing vibration of the vibration device whose vibration amplitude and frequency are controllable, based on the received eccentric motor drive data,
wherein the vibration data generator is configured to generate the vibration data, which indicates a second waveform having an envelope with a change trend that correlates to a change trend of an envelope of a first waveform indicated by vibration of the eccentric motor vibration device according to the eccentric motor drive data, the second waveform having a higher frequency than the first waveform and sampled at a second rate higher than the first rate.
