  • Patent number: 5647007
    Abstract: A bonnet style hair dryer includes integral left and right speakers. Each of the speakers is positioned proximate a respective ear of the user when the bonnet is placed over the user's head. A stereo audio cable is connected to the speakers with the opposite end connected to a stereo audio jack positioned within the bonnet. The speakers can thus be connected, via a removable external audio cable, to any suitable audio source so that a user can receive audio entertainment or information while her or his hair is being dried. The external audio cable may have an in-line stereophonic audio amplifier incorporated therein. The speakers have speaker cones which are heat formed from a polyester film to increase the efficiency of the speakers. The speaker cones may also have radial or tangential ribs formed therein. A one-piece folding speaker holder provides for toolless mounting of the speakers within the hair dryer bonnet.
