Abstract
A vibrating toothbrush, which includes a handle member, an elongated arm which has a brushhead at the distal end thereof, and a drive assembly for moving the brushhead at a selected velocity. Responsive to an on/off switch on the toothbrush is an on/off variable, which enables a master clock to produce a drive signal, the on/off variable being reset by a 120-second timer. A quadtimer variable, when in the enabled state, is responsive to the on/off switch to produce an audible signal and a difference in brush velocity at 30-second intervals within the 120-second period.
