When the phototube is shined by the light which is produced by proper sound modulation LED of IR light transmitter(the transmitting distance is 137.2m), this circuit can provide 15Ω loudspeaker with 500mW maximum output. This system is suitable for the occasion where's difficult to install the electric wire, and it can be used when the wave length is about 0.9μm.
