Musical Greeting card

[Jinesh]

Hi. I remember that when I was a kid, there existed these musical
greeting cards (real ones, not e-cards) -- you opened it up, and there
was a chip inside that triggered and played "Happy Birthday" or some
Christmas song, or something.

1. How do those things work? (what chip do they used, how is it
constructed, etc.)

2. How can I manufacture my own?

3. (barring that) How can I find a place that will custom-build these
for me?

Thanks!

you can buy the recordable ones, record your song/message, then rip out the hardware, put it into the new card. unless you are trying to go commercial with this.

that would be your easiest solution
