a low power wireless audio power amplifier

This low-cost project allows audio reproduction from a TV without disturbing others. It eliminates the need for wired connections between the TV and loudspeakers by utilizing invisible infrared light to transmit audio signals. Without the use of lenses, a transmission range of up to 6 meters is achievable. The range can be extended by incorporating lenses and reflectors with infrared sensors that include both transmitters and receivers.

The project utilizes an infrared (IR) audio transmission system designed to wirelessly transmit sound from a television to loudspeakers. The core components of the system include an IR transmitter, an IR receiver, and the loudspeakers themselves. The IR transmitter is connected to the audio output of the TV, converting the audio signals into modulated infrared light signals. This modulation allows the audio information to be carried effectively over the infrared spectrum.

The IR receiver, positioned within the designated range, detects the modulated infrared signals and demodulates them back into audio signals. These audio signals are then amplified and sent to the loudspeakers, enabling sound reproduction without any physical connections. The system is designed to operate effectively within a range of 6 meters, which is sufficient for typical home environments.

To enhance the system's performance, the use of lenses and reflectors can be incorporated. Lenses can focus the infrared light, thereby increasing the effective transmission range beyond the standard 6 meters. Reflectors can be strategically placed to direct the infrared signals toward the receiver, minimizing signal loss and improving overall audio clarity.

The entire setup is powered by a low-voltage power supply, ensuring safety and efficiency. The simplicity of the design makes it an attractive solution for individuals seeking a cost-effective and non-intrusive way to enjoy audio from their televisions without disturbing others in the vicinity. This project provides an innovative approach to wireless audio transmission, leveraging infrared technology to achieve a seamless listening experience.Using this low-cost project one can reproduce audio from TV without disturbing others. It does not use any wire connection between TV and Loud Speaker. In place of a pair of wires, it uses invisible infra-red light to transmit audio signals from TV to Loud speakers, Without using any lens a range of up to 6 meters is possible. Range can be extended by using lenses and reflectors with IR sensors comprising transmitters and receivers..
