  • Patent number: 6658687
    Abstract: A radio hairbrush generally comprises a body, having a plurality of bristles dependently secured thereto; a handle; a radio receiver integral with the body; and an audio output device. The radio receiver is contained within a cavity internal to the body and all controls for the radio receiver are sealed to prevent the ingress of fluids to the cavity. The controls may include an ON-OFF control for the radio receiver and a volume control for controlling the level of sound generated by the audio output device. A plurality of orifices through the body are positioned adjacent to the audio output device for allowing the emanation through the body of sound waves emitted from the audio output device. A flexible membrane, such as a thin, plastic sheet, is interposed between the audio output device and the orifices to prevent the ingress of fluids through the orifices to the cavity.
