1. A stand-alone audio label for use in product presentation adapted for attachment to a product to be sold, said audio label comprising:

  • a circuit board substrate;

    an adhesive layer attached to said substrate so that said audio label may be affixed to a product to be sold;

    a photovoltaic cell attached to said circuit board substrate;

    a sound-storing, sound-retrieving microchip attached to said circuit board substrate and connected to said photovoltaic cell so that said photovoltaic cell provides power to said microchip, said microchip being adapted to have audible sounds pre-recorded thereon in the form of signals which said microchip, upon activation, can communicate to replay said audible sounds; and

    a sound reproduction unit attached to said circuit board substrate and connected to said microchip so that when said microchip communicates signals to said sound reproduction unit, said signals are converted into audible sounds;

    said sound reproduction unit having;

    a circular electromagnetic coil with a circular opening defined therein and top and bottom surfaces, a thin magnetic disk having a top surface and a bottom surface opposite to said top surface;

    said magnetic disk being movably disposed within the circular opening of said circular electromagnetic coil;

    said magnetic disk being held in moveable relationship therein by first and second flexible rubber membranes, said first membrane being connected to the respective top surfaces of said magnetic disk and said electromagnetic coil, and said second membrane being connected to the respective bottom surfaces of said magnetic disk; and

    said electromagnetic coil, said magnetic disk further having a protrusion with a rounded nose attached to the bottom surface thereof so that said rounded nose of said protrusion is disposed in moveable contact with said product;

    whereby upon the communication of the signals from the microchip to the sound reproduction unit, the electromagnetic coil is energized intermittently in response to said signals and upon the intermittent energization of said electromagnetic coil, said magnetic disk is moved intermittently in a vibratory fashion such that said protrusion vibrates said product to reproduce an audible sound.
