An audio label comprising a circuit board substrate with a sound-generating microchip and a photovoltaic cell both attached to the substrate such that the microchip is electrically connected to the photovoltaic cell so that power is provided to the sound-generating microchip. A sound reproduction unit is also attached to the substrate and is connected to the sound-generating microchip so that the microchip communicates signals to the sound reproduction unit which are then converted by the sound reproduction unit to audible sounds. A system for audio label operation is also disclosed. The system includes a separate transmitter which transmits electromagnetic waves, such as light, infrared or radio waves to one or more audio labels which have electromagnetic wave receiving circuit elements, such as phototransistors disposed thereon. The transmitter thus sends wave signals to each label each of which then converts the wave signals to electric signals which each sound reproduction unit then converts to audible sounds.
