The thing you are looking for is a telegraph sounder.  There are currently several on ebay currently asking $10 up.  That is a place to start.

I did run across a simple DIY set as well

A rather more ambitious and better sounding project is this

good luck

> First, thanks to all that have made suggestions....I should have been more clear in my original post...I'm teaching landline telegraphy (the electric telegraph) and not radio telegraphy.  As such, a buzzer or other device that would emit a tone when the circuit closer is closed would not be suitable.  I'm looking for something that will energize when the circuit closer is closed and release when it is opened.
