I am trying to build this music box that plays a music that is about 30 seconds or so long and will play it until the music box is closed. What can I use to make this happen it needs to be small and not take up a lot of room. Also is there a way for me to make the in side turn (like in a music box) electronically, again it needs to be small.

I don't know much about engineering trying to learn as I go so detailed instructions or a link to them would be greatly appreciated.
Thank you.

This is the locket I might use or I'll use something bigger if needed like 3 or so inches wide and tall.

Any Ideas???

 

You can find those little "recorder" chips inexpensively, I think even Radio Shack had them at one time.

 

Have you heard an electronic greeting card play squeaky music barely loud enough to hear? That is what you will have.

A 2 inch or 3 inch speaker might sound good but is bigger than the thing you want to put it in.

 

Here you go - they really don't sound that bad.

You will probably have to find a miniature flat speaker to replace the one that comes with it but they're easy to find there or at places like www.goldmine-elec.com/

 

Thank you for the replies.

Does anyone know where I could find the shell, I was thinking of using a clock or picture frame. Does anyone have an idea of how I can make the moon turn around (motor of some sort) and light up when I open the lid.

Is there a way I can make the sound better on the video recorder thing? And how can I program it to play a certain tune.
Thanks.

The project I am doing is trying to make this locket as a gift:

 

They make tiny motors for pager buzzers but not any that turn very slowly that I'm aware of.

Don't let that recorder fool you, it has good sound.

Your only alternative is to come up with a tiny microprocessor that you could program midi-like notes into, the recorder will take anything you throw at it so you could play the tune on a piano, guitar or take music off something like a pre-recorded CD.
