Abstract
A vibration control device configured to provide a haptic function and control a vibration device driven by a sine wave. The vibration control device includes a sampling frequency signal generator and a sine wave synthesizer. The vibration control device is configured to generate a sampling frequency signal using a clock signal, wherein the sampling frequency signal is related to an operation cycle of a digital filter; and the sine wave synthesizer includes the digital filter. The digital filter is configured to adjust at least one of a cycle of the sine wave and amplitude of the sine wave using the sampling frequency signal and a plurality of coefficients of the digital filter; and generate an adjusted sine wave.
