How to make a portable speaker from an active computer speaker and a poor quality portable speaker?

Question

Electronics

There are good quality old active computer speakers and there is a deshman portable speaker from aliexpress. I would like the active speaker to work from a portable battery and connect to the phone via wire or bluetooth. How to do it?

1. Take a basin from the mother, or rather a plastic rectangular box from under the seedlings. Seriously. Put two plastic containers in it, in which the folder takes lunches to work.
   
2. In these boxes we collect all the screws and bolts and bolts when disassembling the devices. Each device in its own box.
   
3. Arrange yourself a comfortable seating area with good light.
   
4. When parsing, take pictures in good light more often of what it is like and how it was connected to the phone from different angles, follow the focus.
   
5. Disassemble both devices and try on the necessary insides of one to the insides of the other. Please note that this will degrade the sound. You can try to insert a battery and a board from a small speaker into a large one and turn on the big one as usual in the computer and listen. If you are satisfied, continue.
   
6. The next step is to look at the resistance written on the dynamics of a large column and the resistance on a small one. This is the number next to the letter omega. If found and the figure is close in value, then this is a good sign. No, you can still try.
   
7. Unsolder one wire of one of the large speakers (the one that was dismantled, while the second passive one can be left alone for now). Attach this speaker with a piece of wire instead of the speaker in the shallow one. Turn on the small one, listen at different volumes? Started up? Works? - count yourself lucky.
   
8. Look at the small speaker board. Is she Mono? there you can see the second contact, where could the second channel be connected? Unclear? Post pictures of the board and the insides of a small column with a separate question, ask here where to solder the second channel. If you find somewhere - solder a couple of wires, then attach a mono-jack or tulip connector to the main retro speaker to connect a pair to it.
   
9. Try on the inside of a small column inside the old one already properly. Some plastic partitions can be melted with a neatly sharpened fixspray soldering iron (it’s not a pity), don’t ruin the main soldering iron - you will regret it later.
   
10. O! Remembered! Bingo! Check out Alex Hoover 's YouTube channel . The dude is very cool and, having a workshop, a 3D printer and straight arms, he bothers a lot to tell how to make cool things in the kitchen from sanitary ware and sticks with arms growing from the pelvic area. He has a website with instructions, diagrams, tested components and parts to upgrade speakers without breaking the Chinese washer. For the price, it will come out for that, and even, maybe, add a radio or make an Internet radio optional.
    
11. Well, what is there ... the desire to torture your diaiwai has not disappeared yet?
    
12. Solder the excess, try on, saw through, try on again so that the card fits in and everything is inserted everywhere. Solder the speakers. You plant everything on hot snot so that it does not hang out, collect everything in a heap by tapping with a hammer.
    
13. Do not worry. Ten times more, everything will have to be taken apart and re-glued, because they forgot to solder something, because they forgot to unsolder something, because, oh damn, the wire had to be threaded through the hole ... This is normal. Always so.
    
14. You will get some kind of crap, which is good if it works and does not smoke at the same time.
    
15. There, something is sure to unsolder after a short time or fall off, or short-circuit, but you will be too lazy to fix it, because you remember how you cursed when it was all re-glued and collected.

I looked at the profile. Krch. About the mother and the folder, I’m like that, for a red word.
Well, it’s ichsto from literary considerations of style. do not piss

With your profile, I would be sawing a wifi internet radio on an ESP8266. Battery power and charging are not difficult to add from separate components.
