PURPOSE: A vibration generating device capable of adaptively controlling a frequency match characteristic is provided to drive a vibrating unit with an optimum resonant frequency by monitoring the current waveform of the driving unit through a simple circuit.;CONSTITUTION: A vibration generating device capable of adaptively controlling a frequency matching characteristic comprises a signal generating unit(10), a driving unit(20), a vibrating unit(30), and a current monitoring unit(40). The signal generating unit generates a drive signal according to a fixed driving frequency. The driving unit drives the drive signal of the signal generating unit. The vibrating unit is vibrated according to the drive signal. The current monitoring unit comprises a comparing part which compares the internal voltage of the driving unit with a reference DC voltage and a frequency control part which determines a match between the resonant frequency and the driving frequency by analyzing the current waveform and by controlling the frequency generation of the signal generating unit.;COPYRIGHT KIPO 2011
