The transmission is done by using an infrared LED and adding the audio signal in the IR LED to transmit through the IR beam. This circuit is mainly used for obstacle detection using an IR LED. The similarity to the transmitter can be.

The transmission is done by using an infrared LED and adding the audio signal in the IR LED to transmit through the IR beam.

So this circuit can be built with two transistors like NPN and PNP. We have use BC557 PNP transistor here to reverse the effect of TSOP means whenever the output is HIGH LED will be OFF and whenever it detects IR and output is low LED will be ON.
