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.

These pulses are then sent to an infrared LED. For the transmitter side, an audio input from PL1 frequency modulates the VCO section of a HEF4046BT PLL chip. The VCO output drives Q1, a switching transistor. Q1 drives two IR LEDs. The signal produced is around 100 kHz, FM carrier VCO sensitivity is around 7.5 kHz/V. See also: Wireless Headphone Receiver
