ABSTRACT:
The drive system drives a brushhead at a driving frequency. The drive system includes a frequency modulation system which changes. the driving frequency about a center frequency in such a manner, with selected frequency deviation and modulation frequency, which interacts with the resonance of the brushhead to produce a change of amplitude in the movement of the brushhead within a range of 5-30%.
