This diagram shows how to connect all the parts. If you connect the batteries to this, the second diagram shows how to do it.

I found a discarded battery acid bottle for this case. Battery acid bottles often come with a motorcycle battery, so be careful if you use a battery acid bottle. But you can find another option. If you have a 3D printer, you can make your own case.The front black cover of the case is made of a non-used jadel ck 4 speaker.Try to get an idea of the case by using the images shown here.

As a last Step, add everything. When supplying power to the bluetooth speaker we designed, give about 5V.

We have finished creating our bluetooth speaker. Now enjoy it. Turn on the bluetooth on your smartphone and connect it to the speaker. Now have fun.
