Original Abstract Submitted
A power toothbrush device () including a brush head member () having bristles and a drivetrain assembly () having a drivetrain shaft () configured to drive the brush head member. The drivetrain assembly includes a resonator () configured to rotate about a central axis (A) to move the bristles in a first movement pattern; a resilient member (); a magnet (A, B, A, B) connected with the resonator; and a conductor (A, B, A, B). As the resonator rotates and the magnet moves toward the conductor in a first direction, a force is generated upon the magnet in a second direction that is opposite the first direction, and the force generated upon the magnet thereby causes a rotation of the resilient member about a second axis that is different than the central axis.
