External speaker wiring for iPod

I bought a bargain external speaker and mic for an iPOD. I wanted to play a tape recorder device direct into the speaker by plugging the speaker + mic into the 3.5mm (1/8 inch) output of a tape recorder.

It wouldn't work even when changed some of the connections after I had checked the pinout for the four connectors on the 3.5mm plug and

When I opened up the external speaker + mic there was circuit board. What does the circuit board do?

And why does the speaker have four connections ???

I think you've described an amplified speaker powered by the ipod.

What's a "tape recorder"?

Wouldn't those spools bind up when you put it in your pocket?

Does the output on the tape recorder drive a set of headphones?

A tape recorder is just like a wire recorder except it uses flimsy plastic tape instead of nice sturdy steel wire.
