i need to do a project which is about IR AUDIO TRANSMITTER AND RECEIVER to amplify the audio signal to headphone
the circuit is as follows.

however, i dun know wt is the function of the three transistors in the receiver part exactly. can someone answer me?
also can u briefly tell me the working principle?
