Abstract:
1. A resonator assembly for a power toothbrush having a handle portion and a head portion having a mounting assembly, the mounting assembly fitting into a mating portion of the handle portion, the handle portion having a drive system, comprising: an elongated single beam rod member, having a back assembly at a rear end thereof, cooperating with the drive system to move a proximal end of the rod member in a back and forth transverse direction, the rod member being adapted to receive a workpiece at a distal end thereof; and a mount member which surrounds and mounts the rod member to the mounting assembly, wherein the mount member has a substantially circular periphery surrounding the rod member for pressing contact with the mounting assembly, the mounting member being movable along the rod member to provide a desired frequency of performance and amplitude of brushhead movement wherein the distal end of said rod member accordingly moves about the mount member in a back and forth transverse direction opposite to that of the proximal end thereof at a selected frequency.
