Mini Bluetooth Speaker

I have prepared three different versions - hexagon, star and flower design. Size of the speaker case is about 7x7x7cm.

List of material required to build the bluetooth speaker：

2” speaker driver
3W bluetooth PCB(5V DC input)
DC jack
3D printed speaker case

I was not able to identify the brand and model no of the PCB, but any small size bluetooth PCB will just work fine.
