Generating ping sounds

[Heckler]

Here's a low tech idea...

How about if you use an old doorbell or electromagnet or solonoid to clank or ping or ding something to get the sound(s) you want. Obviousily this could be controlled by a sufficient transistor or relay controlled by the PIC.

I thought about that, but really need a solution that can be produced in a decent quantity (1000 units or so). I have seen electronic shooting gallery games make this sound, I was just wondering if anybody knew how they do it. I don't really have a background in analogue electronics, so not sure of the best way to go.
