I think the buzzer will be an appropriate piezo element driven by an oscillator preferably at it's resonant frequency.
Look up Piezo in wiki. Any old oscillator will do, if you want to play at builing one, use a 555 timer.

Hi, Guest. If you're a member, please remember to log on - that way we'll know who you are, you'll get e-mail notification of replies & new posts on threads you're subscribed to, and you'll be able to accumulate "number of post" counts to take you through the levels of "browser" - "active contributor" & so on. Hopefully, you'll also be able to tot up some GAs (Good Answers).

If you're not logged on, you won't get any of these wonderful advantages .

And you prob'ly won't have as much fun - which IMHO is more to the point.
