Hi I'm wondering how to make a small speaker thing

I want to put a small speaker with memory into a cardboard box (somewhere in the range of 12 x 8 x 3 cm), which is activated by a pull switch (pull a chain to activate the speaker).

How would I go about this?
What sort of parts would I use?

Hey Aurora,
Welcome to the forums!

I will always recommend the DFplayer Mini for a compact noise making solution, paired with the Enclosed speakers and a AA battery pack, its very compact.

Now the pull chain switch is a bit more difficult as we do not stock them. I could imagine using a on/off momentary button which is activated by the chain being pulled on a track, maybe held by a spring so that it goes back to position after its let go. That part of the project would take some definite ingenuity to come up with something that would last.

I’d suggest something similar to Blayden’s solution.

If you attach your chain to a pivot such that when you pull on the chain the other end pushes up on a limit switch (Micro Limit Switch (Roller Lever) - 2 Pack | goBilda GB-3103-0001-0001 | Core Electronics Australia) would likely get you there.
