Bluetooth Speaker 10w (DIY)

I would like to present my first Bluetooth 5.1 Music Speaker with a power of 10 watts.
The design is as simple as possible and does not require any supports during printing. PETG/PLA plastic can be used for printing.

List of electronic components you will need:

1. 2pcs: Speaker 4 Ohms 5W 52mm Round 18mm (32mm long stroke).
2. 1pc: MH-MX38 Wireless Decoder Board Bluetooth 5.1 Audio Module.
3. 1pc: TP4057 (or TP4056) 1A 3.7V Lithium Battery Charging Board.
4. 2pcs: INR18650 3.7V Lithium Battery (You can also use a single battery).
5. 1pc: ON-Off 2 Pin Round Snap Rocker Boat Switch 14.5mm size.
6. 1pc: Type-C cable extension (female connector).

Visualization of component connections

With this connection diagram, you can use the Bluetooth speaker directly from the mains (without charging the batteries), or you can use it only from the batteries, or simultaneously from the mains and charging the batteries (when the switch is turned to the ON position).

In this project, I did not add a charge indicator or a LED power status indicator because this is my first project and I wanted to make it as simple and convenient as possible. I will upgrade this project over time, and I have also added many new designs.

Thank you for your attention.
