This Bluetooth USB Speaker unit was brought to me by a recently acquainted Ayurveda Doctor with the complaint that the charging port and switches got ripped off, when he tried to open it. I did not ask him why or how and just coolly accepted the unit. The screws as well as the switch button arrays were misplaced by him and could not be traced. Well, what a strange thing to happen!

My role was to try re-fixing the ripped off charging port and switches and the doctor said he would try to trace the missing items. Here you can see how the port got ripped off:

The switches you see in the first picture above were all turned up with its legs detached from the bottom. These were just holding on to the metal body soldered! I carefully pressed the switches back to its place and applied solder and fixed them properly. I then soldered two wires (+) and (-) on to the detached port, as exact replacement was not available. Please see the third picture above. Then cleaned the seating place thoroughly and fixed the body of the port using Fevibond and Superglue.

Then soldered the body of the port firmly on whatever little track that was remaining. Then soldered the wires on the (+) and (-) positions at the shorted place possible. Then applied power and was glad to see that the charging was taking place. The battery as well as the speaker was at the bottom of this unit and I never bothered to open it and see, as these were fixed with glue and not screws. I soldered the two speaker wires in its place, which I had removed to carry out the repair work. Left it for charging and tried playing from USB as well as Bluetooth.

It worked very well. I fixed the board back in its place using appropriate screws from my collection. Mission accomplished with minute but great satisfaction getting added to the bag because of the intricate work involved. (The doctor could not trace the button array and I left it open, as desired by him! These custom made buttons are not available in the market!)

    Maybe it is time for you to also own at least a small 3D printer dear Parasuraman?
    So you also will have the option to create parts that are not available in the market. I recently now own 2 Creality printers (one older Ender 5 Pro, and one brandnew K1C to also be able to print superfast and with stronger higher temp carbon enhanced and similar filaments). And also previously had used another brand Anet 3D printer I had fixed for a friend before. And I now started learning to design my own designs with the completely free and open software OpenSCAD.

      Oh My God! I do not think I can afford to get one! I may have to only seek outside sources, which to my knowledge are nowhere near! Thanks for your comments and inputs!
