Attention About the Welding
1. Loudspeaker is strictly prohibited to be sucked together with metal (when adding welding electronic wire, be sure to fix the loudspeaker. Especially iron metal, otherwise it will produce noise)
2 point tin temperature as low as possible, generally 30w-40w soldering iron is appropriate, the temperature is too high Solder pad may fall off, skin, tin iron on the pad stay time should not be too long, generally controlled at about 1 second, can not be welded to the inside of the pad, otherwise silent phenomenon
3. The horn is connected with external electronic materials, and must be correctly welded at the two outermost points of the welding pad
