2. Voice coil break
If the resistance value is Weld a piece of enameled wire near the voice coil.
3. Break of loudspeaker lead
Due to the frequent oscillation of loudspeaker paper basin, the weaving wire is easy to break, sometimes the wire has been broken, but the cotton core wire still adheres to the connection. This kind of weaving thread is not easy to buy and can be replaced by a slightly longer flexible wire.
4. Coil Burning
Measuring loudspeaker leads with Multimeter R * 1 gear indicates that the voice coil is burned if the resistance is close to 0_and there is no "click" sound. Before replacing the voice coil, the debris in the magnetic gap should be cleared first, then the new voice coil should be carefully put into the magnetic gap, and the voice coil should be corrected. While listening, the upper and lower position of the voice coil should be fixed with strong glue.
