Musical card mechanism, turns on when card is opened. Where can I find them?

Question

I would like to find a mechanism that will activate when a book that it is in is opened. It can be pre-recorded or one that I can make the recording myself. I think these are button battery operated. The only ones I could find on the net were from China and only sold by the thousands
to merchants. I only need around a dozen or so depending on the price. Please help if you can.
Thanks,
Weston

Answer 1

Do a Yahoo search for " greeting card musical modules ". When the addresses come up, look at the one from National Art Craft .com. It has what you want. ( The address was so long I thought I would mess it up )

Answer 2

I think I saw something like that at the local art and craft store called the Rag Shop.
I also think they have them at the Build-A Bear store at the mall.
