Experience making PCBs is also required. Finally, connect the two wires inside the cable to the two wires on the speaker polarity does not matter.

Find one that is as close to the size of your components. They should follow the walls of the tin. I recently built a bluetooth stereo speaker set out of some old cheap stereo speakers from the 70's they sound fair but not great.
Once you have the foam completely in the tin, turn the speaker over and apply some tape or glue on the back of it. Substitute as seems reasonable.
Maybe make a few and I'll buy them..?? You are no help. These speakers can easily fit in your pocket!

I use a metal punch to mark the hole locations and brad point bits for wood to drill the holes. The battery holder barely fits into the tin and the heat shrink tubing protects the leads from abrasion. Don't forget to use heat shrink tubing on all of your exposed connections.
You won't have to buy a single thing for this Instructable. By Maverick14 Follow. Plug in the cable and make sure that the two signal wires connect and the ground connects to ground.
When the diaphragm needs to moves up and down, the suspension allows it to. The amplification of the system should take place in the LM386 where it belongs and not in the source providing the signal.
Solder them into place in the following order -- switch, audio jack, battery holder, speaker. In any case, both the easy and elegant modifications place the burden of amplification on the LM386 and the sound is considerably better at higher volumes. Transfer I had and still have considerable difficulty getting consistent transfers onto the copper board.
