Abstract

A Infrared Cordless Headphone project is design here is to reproduce audio from TV without disturbing others. It does not use any wire connection between TV and headphones. In place of a pair of wires, it uses invisible infrared light to transmit audio signals from TV to headphones. Without using any lens, a range of up to 6 meter is possible. Range can extend by using lenses and reflectors with IR sensor comprising transmitters and receivers. Here an audio amplifier is to provide signal amplification to the level where it can be heard through a headphone. For maximum clarity, we must adjust the pot meter, VR2. Direct phototransistor towards IR LED of transmitter for maximum range. A 9-volt battery can be used with receiver for portable operation. This Infrared Cordless Headphone was design with a basic design, the first objective for that is to use Infrared Cordless Headphone without disturbing when it comes to someone pleasure of enjoying music or heard information from TV.
