Abstract
An oral hygiene device ( ) is disclosed having at least two motors ( ) to simultaneously vibrate and impart motion upon the head portion of the oral hygiene device ( ), most beneficially at the tip ( ). A first motor ( ) is positioned in the handle housing ( ) of the device ( ) to impart a first frequency of movement to the tip ( ). A second motor ( ) is located in a head portion, generally in a shaft ( ) of or an oral hygiene attachment to the device ( ), to impart at least a second frequency of movement onto the tip ( ). When both the first and second motors ( ) are activated, the resulting movement of the tip ( ) of the device ( ) may include complex, substantially random movements, depending in part on the frequencies at which the motors ( ) are operating.
