  • Patent number: 4841587
    Abstract: A musical mat of the present invention includes a mat portion having a pillow connected to one end thereof. The mat includes a casing with a resilient padding material therein for supporting a person. A pair of speakers are mounted in the pillow and spaced apart so that a person can lie with his head between the speakers. A radio, or other audio transmitting device, is maintained in position within a pocket on the mat, and may be connected to a plug which is electrically connected to the speakers in the pillow, to transmit the audio signal to the speakers. The electrical conductor connecting the plug to the speakers is mounted within the mat casing and within the pillow, such that the wires do not interfere with the person lying on the mat. The pocket for retaining the audio transmitter is selectively fastened to the mat, to allow removal of the pocket and transmitter for use of the mat without the sound system.
