This project allows for wireless transmission of audio from a television to headphones using infrared (IR) technology. It eliminates the need for physical connections between the TV and the headphones. Instead of traditional wiring, it employs infrared light to transmit audio signals. The effective range is up to 6 meters, which can be extended by incorporating lenses and reflectors with the IR sensors that function as transmitters and receivers. The IR transmitter utilizes a two-stage transistor amplifier to drive two IR LEDs connected in series. An audio output device is used in reverse to couple audio output from the TV to the IR transmitter.

This wireless audio transmission system operates by converting audio signals from the television into infrared light signals. The audio output from the TV is fed into a reverse audio output device, which modulates the audio signal and sends it to the IR transmitter. The transmitter, powered by a two-stage transistor amplifier, drives two IR LEDs that emit infrared light. This light carries the modulated audio signals through the air.

At the receiving end, a pair of headphones equipped with an IR receiver detects the infrared signals. The receiver demodulates the signals to retrieve the original audio content, which is then sent to the headphones for playback. The use of lenses and reflectors can enhance the effective range of the transmission by focusing the infrared light, allowing for a greater distance between the TV and the headphones.

This system is particularly advantageous in environments where physical connections would be cumbersome or impractical. It provides a flexible solution for enjoying audio from a television without the limitations of wires, making it suitable for various applications, including home theaters, public presentations, and personal listening experiences. The design can be optimized for performance by selecting appropriate components for the amplifier and IR LEDs, ensuring clear audio transmission with minimal interference.Using this low amount Project one can carbon AUDIO from TV after advancing anyone. It does not use any wire amid TV and HEADPHONE. In abode of brace of affairs it uses airy Infrared ablaze to address audio signals from TV to Headphone. After application any lens a ambit of up to 6 meters is possible. Ambit can be continued by application Lenses an d Reflectors with IR sensors absolute transmitters and receivers. IR transmitter uses two-stage transistor amplifier to drive two IR leds affiliated in series. An audio achievement agent is acclimated (in reverse) to brace Audio achievement from TV to the IR transmitter. 🔗 External reference
