A cube, with speakers on 5 faces.

Can you hear me now?

The picture shows a small LM741 amplifier circuit to power the speakers. You can use any of a number of ways to power the speakers.


If you've got the speakers (36mm dia x 1.75mm mount height) that I've got, then just print, snap in the speakers, wire them up to something and play.

Otherwise, tweak the openscad for your speaker as per http://www.thingiverse.com/thing:40689 (the speaker mount object that this is derived from).

Amplifier: G Wellwood - Cutcher LM741 Amplifier - http://www.gwellwood.com/electronics/electronics-level-2/

The box is the object.

The circuit is one example of what could be used to power speakers inside the box.

I happened to have some LM741 chips around and the proper components to build the small amp.

ebay has pre-built or kit amps which use much better amplifier components than the LM741. It all depends on what it is you intend to accomplish.
