2. Raw materials used in the homemade Lotus to 3.5 audio cable-two lotus heads and 1 earphone sockets.

3. Peel off a short piece of wire from the first section of the shower head and wind it around the earphone socket.

4. Weld the street with electric soldering iron to prevent it from falling off.

We wrap the earphone socket with heat shrinkable tube.

6. Put the heat shrinkable tube on the earphone socket.

7. Heat the heat shrinkable tube with a lighter to make it tightly wound.

8. Because the circuit board is not used during welding, it is directly welded. After putting on the heat shrinkable tube, the pins of the earphone socket are uneven, so we are wrapping some electrical tape.

9, and then put on a thick heat shrinkable tube.

10. Heat the heat shrinkable tube again with a lighter to make it tightly wound.

1 1. When welding, pay attention to the pin definition of earphone socket and the pin definition of Lotus, so as to ensure the welding is correct. 3.5mm three-section earphone plug, the first and second sections are left and right audio positive poles, the third section is grounded, and the iron sheet outside the lotus male head is grounded. The middle pin is the positive electrode, and it can be welded after measurement.
