Description
It's a 3D-printed Bluetooth speaker made from recycled parts. I used two 60mm 3W 8ohm speakers I found in a drawer, combined with an XH-A232 module to amplify the signal, and an HW-770 Bluetooth receiver, all powered by an 18650 lithium battery, all components can be purchased for next to nothing online.
The speaker was designed to keep its dimensions to a minimum, while still ensuring good acoustics thanks to the optimized reflex port.
I recommend 100% filling to minimize vibrations while listening, and placing the supports only on the build plate to prevent them from getting stuck inside the reflex port, making them difficult to remove. I used standard PLA, but you can play with different materials to find the best frequency response. 2.5mm wood screws are fine, but I recommend heating them before inserting them and tightening everything as well to avoid drafts.
