BlueTooth music speakers

I used this solution to recover an old speaker that I would have otherwise thrown away. I bought this radio with Bluetooth receiver and USB / mSD player, an amplifier and a power supply on Amazon for a few euros and everything is great.On the back I replaced the speaker connectors with a small panel housing a male Schuko connector and an on/off switch, both of which were salvaged from a non-functioning PC power supply. The dimensions of the holes on the panel are: Hole for Schko soket (Schuko cable) male socket: 27x19.20 mmHole for the switch; 19.80x12.80 mmHole provided on the acoustic box: 47 mm Power supply Good print! If you found it useful, and if you like, you can offer me a coffee!, it will be an extra motivation to continue designing.Thanks to Google Translator for help with translation. ;)Print SettingsPrinter Brand:Creality Printer: Ender 3 ProRafts: No Supports: Doesn&#39;t MatterResolution: .20 <
