Using this low-cost project one can 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 metres is possible. Range can be extended by using lenses and reflectors with IR sensors comprising transmitters and receivers. IR transmitter uses two-stage transistor amplifier to drive two series-connected IR LEDs. An audio output transformer ....etc

HEADPHONE AMPLIFIERS
INTRODUCTION
A headphone amplifier is a kind of audio amplifier designed particularly to drive headphones instead of loudspeakers. Most commonly they are found embedded in electronic devices such as integrated amplifiers, portable music players and televisions, but standalone units are not uncommon
Advantages
Its advantages are ...
• low output impedance to drive several pairs of phones
• the active gain stage is, almost, perfectly logarithmic and ...
– is independent of the a ....etc

INFRARED HEADPHONE

ABSTRACT

The circuit for INFRARED HEADPHONE is designed to demonstrate the transmission and reception of audio signal through ! infrared radiations. The infrared rays generated by the transmitter circuit are received by the receiver circuit after transmission through air. This communication is much more effective than ordinary communication. It helps to receive audio signals from any audio device like T.V,radio etc.
i
without disturbing others. It provides minimum transmission loss. It is a low ....etc

Cordless power controller
Introduction:
We live in a world of automation and full of facilities only because of
technology. In this world we have become so much addicted to technology so
that we would rarely try to turn on a television ourselves rather than searching
for the missing remote control for turning on the television.
Controlling electronic devices and domestic appliances using a remote
control is an attractive facility provided in the present consumer electronics
products. This product CPC (cordless power controller) i ....etc
