How do you remove a small microphone and supply a small audio current?

Question

I have a Transmitter-Reciever set and I want to hook up a signal from a headphone jack.

Answer 1

you have to look at the schematic and figure it out.

I hope you don't want to hook up the headphone to the microphone? That  makes no sense.

If you can get at the speaker, you can (maybe) put a the headphone in parallel with it, with a resistor in series to cut down the volume.
