Abstract: A low noise vibration apparatus is provided to reduce vibrational noise by offsetting sound waves generated by a transducer. A low noise vibration apparatus includes a signal distributor(111), a filter(112), a speaker(113), and a transducer(114). A signal distributor distributes an input signal. The filter regulates the strength at a frequency and the phase of the input signal distributed in the signal distributor and outputs the regulated strength and phase of the input signal. The speaker generates sound waves for offsetting and interfering noise due to vibration of the transducer. The transducer generates vibration according to the input signal distributed in the signal distributor.
