Try some PC speakers, or any speakers with a headphone cable. Cut the male end off the headphone cable and touch the center wire to one of the solder points on the speaker.

If you really wanted to build a circuit you could use a simple op-amp.....I think.
No.
An opamp does not have enough output current to drive a speaker. You need a power amp, not an opamp.

That is why using a powered computer speaker was mentioned. It already has a power amp in it.
