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

EXECUTIVE SUMMARY
The concept of “buying behavior” is of prime importance in marketing and has evolved over the years. It is important to understand consumer buying behavior as it plays a vital role in creating an impact on purchase of products.
The human wants are unlimited and always expect more and more. Mobile pre-paid products and Mobile handsets are no exception to this behavior. This lead to constant modifications of Mobile pre-paid products and mobile handsets and today we see lots of pre-paid products ....etc

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

BATTERIES THAT CHARGES ON AIR
INTRODUCTION
 Lithium-ion batteries power most of the mobile devices like:
 Laptops
 Cell phones
 Portable Playstation.
Merits of li-ion
 lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight.
 Because of the inherent instability of lithium metal, especially during charging, research shifted to a non-metallic lithium battery using lithi ....etc
