DIY audio jack ir blaster - FzWARE
https://fzware.com/diy-audio-jack-ir-blaster.html
DIY audio jack ir blaster This IR Blaster works with iOS App EzRemote. Theory. The process is based on the fact that the IR key codes are series of square waves at 38kHz of main frequency. The duration in time of the square waves ON and OFF defines the codification of a specific key. By considering a common audio stereo channel (2 mono), it can ...

The Audio signal will be transmitted through an IR LED from the transmitter circuit; the IR signals will be then received by a photodiode which will be placed on the receiver circuit. The audio signal thus received by the photodiode will be very weak and hence it will be amplified by an LM386 amplifier circuit and finally played on a speaker.

The circuit provides both audio volume and input channel selection. A stepwise volume control is implemented with a set of small relays and resistors. In a high-end audio system, a noticable sound improvement over potentiomeneters can be obtained, also over 'audio grade' potentiometers. Clearly, the IR remote control provides convenience over solutions with …
Infrared IR Transmitter and Receiver Circuit
https://circuits-diy.com/infrared-ir-transmitter-and-receiver-circuit/
This tutorial explains the simple functioning of an IR transmitter and a receiver using a 555 Timer IC. Here the TSOP1738, which is a transmitter, receives an infrared signal. And a simple IR LED transmits the signal. The receiver TSOP1738 consists of the photodetector, a gain control, a bandpass filter, a demodulator, and a pre-amplifier.
