Abstract

A toothbrush comprises a head including a plurality of cleaning elements attached to the head, a handle, a neck extending between the head and the handle, a motor unit including a motor and a manual winder for manually energizing the motor, and a force sensor configured to detect a user-applied force exceeding a predetermined threshold force, wherein the force sensor causes the toothbrush to produce at least one of an audible signal and a tactile signal when the user-applied force exceeds a predetermined threshold force. An audible signal and a tactile signal may comprise, respectively, muting of the motor and interruption of vibration of the toothbrush.
