What is that musical thingy in birthday cards called?

I'm talking about the little device that you find in the folding greeting cards that play music when you open them. All you can actually see of them is a little white tab. I need to know exactly what they are called so I can get the specs on them for an engeneering/marketing project. Thanks.
