Brown Box Powered Speaker

I had a cheap audio amplifier from AliExpress, a few speakers pulled out of an old TV, a chunk of USB cable, a cardboard box, and half an hour. Looks like I made something! Audio quality isn’t the best, but it will run on a 5V/1A USB power supply and I can plug a radio into it instead of using headphones.

Rear view of the speaker in a box. There is a small audio amplifier PCB on the left side. The black wire, blue wire, and a yellow/brown wire from the speaker connect to this PCB. You can see the untrimmed zip ties.
