1, prepare tools and raw materials
Prepare a stereo Bluetooth headset, preferably of good quality, audio cable, black tape, scissors and stereo.
2, production methods and steps
Disassemble the stereo Bluetooth headset from the edge, put its motherboard aside for use, then take out the battery, cut the red and black wires, and take out the components one by one. Remember to place the microphone carefully. At this time, you can cut the audio cables one by one, and the wires inside are divided into two strands, one of which is connected to the red line and the black line respectively.
When you connect it, you should wrap it with vinyl cloth. This is the left channel of the Bluetooth speaker. The other strand of the audio cable is connected to the interface of the charging port, that is, the auxiliary earphone. When the head of the auxiliary earphone is cut off, the outer sheath can be melted with fire to expose copper color to ensure its wire performance. Similarly, the right channel can also be obtained through the package.
Insert the other end of the audio cable into the back of the audio input, and you can turn on the Bluetooth pairing mode. After successful pairing, you only need to listen to the voice prompts to complete the production, and design the appearance according to your own preferences.
