What is the wiring method of replacing the connector with a 3.5 plug for Sony Ericsson MPS-80 mini speaker? Be specific.

Mps-80, the sound is very good, very pleasant. It doesn't seem necessary to connect the power supply. Actually, it's an active speaker, which needs electricity. So if you use it on Sony Ericsson mobile phone, you will find that power consumption is faster than mobile phone. If you want to modify it, you must provide him with power and audio routing, so the next step is simple. It has four wires, leather as the positive pole and black as the negative pole. The other two are signal lines. If 3.5 plugs (3 wires) are connected, the solutions are as follows: Step 1, to solve the power supply problem of mps-80, you can find a mobile phone charger with USB interface (if you use USB directly on the computer, you can also use chargers if you use other devices such as mobile phones and MP3), cut off the charging end of the mobile phone, peel off the skin of USB wires, and find that 4 wires are positive, the black wire is negative, and the other two are signal wires. Next, connect the USB cable and mps-80 cable in red and black, and wrap them separately (with insulating tape, it will be short-circuited if the package is not good), so that the problem of MPS-80 power supply is solved. Step 2: Connect the signal line. 3.5 Connect the plug to the mps-80 green line, the blue line to the blue line, and the yellow line to the yellow line (one speaker of the MPS-80 is green line, one is blue line, and both have yellow lines, which are connected to the plug yellow line together) and then wrap it with adhesive tape, and it will be OK. Try it, enjoy the music feeling brought by MPS-80, and hope to adopt it.
