Zusammenfassung:	PURPOSE: A vibration generator and a vibration generating method are provided to vibrate a dummy vibrator without an additional exciting unit by transmitting the vibration of a multi-channel vibrator to a dummy vibrator through a vibration transmitting unit. CONSTITUTION: A multi-channel vibrator(11) has at least two resonant frequencies. A dummy vibrator(12,13) has one resonant frequency among the resonant frequencies of the multi-channel vibrator. The dummy vibrator is vibrated with the vibration from the multi-channel vibrator. A controller(14) controls the vibration frequency of the multi-channel vibrator. If the vibration frequency of the multi-channel vibrator is equal to the resonant frequency of the dummy vibrator, the dummy vibrator absorbs the vibration of the multi-channel vibrator.
