Electronic Music Box

You should investigate something like this. That one came up after a very quick google for "programmable greeting card". I had in mind the circuits used in greeting cards that play sounds when you open the card. Another useful search is "greeting card module".

An alternative would be a cheap MP3 player with a bit of additional glue logic to press the play button when the music box is opened. You would need to find a suitable player that would work with the minimum of button presses.

Are you resurrecting an old project? Probably best to tell us all of the information that was extracted last time too. Still 1 to 2 minutes duration?

 

There are units available that take a memory card (camera style) like a Sandisk SD card
and will play whatever music track/s is/are on it
As Steve said you need to do some googling for related products
