|Infrared Audio Transmitter|
Using this low cost Project individual can produce AUDIO from tube with no worrying a person. It does not application some wire relating television and headset. all the rage place of couple of wires it uses imaginary Infrared light to transmit audio signals from small screen to earphone. lacking using several lens a range of up to 6 meters is promising. Range can survive extended by using Lenses and Reflectors with IR sensors comprising transmitters and receivers. IR transmitter uses two-stage transistor amplifier to drive two IR leds connected dressed in succession. An audio output transformer is used (in reverse) to pair Audio output from television to the IR transmitter.
