Infrared based Wireless Optical Audio Transmission
http://www.ijsrd.com/articles/IJSRDV3I30129.pdf
100 Mbps, the infrared communication has a potential of 1 Gbps. It also has a much shorter wavelength than wireless communication, which is easily enough for broadband communication. It is optimal for when large-volume data such as video must be sent at a high speed. Keywords: Wireless, Infrared, optical, audio, amplifier, speaker I.

Infrared audio transmission directly to personal hearing devices: interference-free and safe - even for use in confidential areas. Apart from the home environment, in which the wireless reception of audio signals via infrared light has long since become a popular alternative to the corresponding radio-frequency transmission systems, this technology proves superior to all other …
How is audio transmitted using infrared light? - Quora
https://www.quora.com/How-is-audio-transmitted-using-infrared-light
On receiving side, IR sensor picks up the signal , amplified, decoded to get the audio data, then fed to Digital to Analog Converter(DAC) , amplified via power amplifiers and fed to speakers. This is how audio is transmitted using IR light. However if you want to play any audio using this communication channel the challenging parts are: 1.
Analog Communications Using Infrared Transmission
https://peer.asee.org/analog-communications-using-infrared-transmission.pdf
Another approach involves the use of infrared transmission techniques for the transmission and reception of analog information such as voice signals. This approach is much less costly since the transmitter ... When an information signal at an …
The Infrared Light Transmission Hearing Aid
https://www.rehab.research.va.gov/jour/79/16/2/leshowitz.pdf
In summary, the IR hearing aid utilizes light transmission of sound from a microphone near the speaker in an attempt to overcome the interfering effects of background noise . The IR aid transmits the auditory message imposed on an infrared light beam rather than as a …

This circuit use test waves light receiver signal pulse change LED1. For R1 and C1 be formed control the rate pulse of the circuit. Besides equipment all value in the circuit will give the rate pulse about 600Hz. Other detail see add in the circuit. Note: LED1 may use infrared light instead. Which results in a distance of about 2 meters.

A visible light communication system for parallel transmission of high-quality audio and video signals using illumination white and red light-emitting diodes (LEDs) is presented in this paper. For video transmission, we adopts the pulse width modulation (PWM) scheme at the carrier frequency of 15 MHz, whereas for the analog audio signal, the Sony/Philips Digital …
ECE 4760 Final Project: Laser Audio Transmitter
https://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/s2009/dyz2_jl589/dyz2_jl589/
The audio signal is sent via an analog transmission instead of decoding it into a digital signal. Optical transmission is usually done using with digital signals, requiring hardware for decoding at the receiver end. By transmitting the analog audio signal through laser amplitude modulation, we cut down on the transmitter and receiver hardware ...
