摘要： 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 portion 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.
