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.
Front view of a large TV speaker built into the front of a cardboard box and a smaller speaker built into the top. The speakers are held in place with zip ties. There is a black volume control knob to the right of the front speaker. A blue-cloth wire and a black wire exit the top right rear corner of the box.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.

@blog Nice! A bit of ingenuity, a little bit of thoughtful planning, and some know-how, and you've turned "trash" into something useful. I salute you for respecting all the resources and labor that went into making those "trash" items that you used. Many people would have sent them to the landfill without a second thought.
And thanks for providing enough detail so that others can learn and be inspired.
Thanks Roy. There’s always more to explain, but maybe this can help nudge some folks.
