A Blue Tooth Speaker With Bad USB Repaired
A guy in a supermarket near my house asked me to repair this blue tooth speaker for him. According to his fault description, the buttons on that device were not functioning the way it should be.
In other words, volume button up when pushed the volume would go down instead of up. With a smile, I asked if someone worked on it before and the answer was no.
It was cheap china made speaker and was easy to open it and get it fixed. I took the black shield off and I got inside of it.
This is the top side of it and the rubber covering the buttons actually can peel off easily. Once I did that, this is what I got
It is a very simple design; only two boards, one for the buttons and one for the main board.
I thought there was something beneath the ping part but it was only the speakers and the battery.
When I recalled with the customer say about the buttons, I smiled because I saw the buttons boards, installed the other way around. It was a simple honest mistake.
I took them out just to check and see if they need cleaning. They were fine.
I took the other board to see what is going on there. Look what I found
The USB was broken off board. I re installed it back on board with solid soldering joints and put everything back together.
Functions were restored and sound was just amazing on it. Mission Accomplished.

Good job Waleed! Indeed speaker design has much been improved these days. Smaller speakers produce much more power than they would before and even in plastic housings they sound unbelievably good. Likely because of stronger magnets and better amplifiers. Seeing the photos it looks that the owner made a good deal buying this little but well designed bluetooth speaker.
Thanks,
Albert.
