How to repair the broken iron triangle earphone?
Treatment methods of membrane collapse, membrane crack, membrane shedding and iron powder feeding
Generally speaking, when headphones appear broken sound, noise and bass loss, it is generally believed that these reasons may be caused. First, open the earphone shell. For the earphone with soft cover structure, first remove the soft cover, and then use the sharp tools such as pointed tweezers to pick up the iron net and steel cover little by little until the membrane is completely exposed. Hard-shell headphones can be scratched at the joint with a flat screwdriver first, then they can be easily opened, and finally the film is completely exposed. Big headphones are another matter. In short, the earphone membrane should be fully exposed for easy operation.
Film collapse, for the failure of film collapse, you can use tweezers to clamp a small piece of double-sided tape and gently lift the place where the film collapses. Pay attention to control. After the membrane is repaired, it can be put back to its original state.
The membrane is cracked and it is unlikely to be repaired. Even if it is repaired, the sound quality will be damaged. However, some of them have been successfully processed, and the sound quality damage is very light, which can be ignored. It is to dip a needle into a little 704 glue (also called vulcanized silica gel) and apply it to the crack. Be careful not to be too thick, just cover the cracks. Then install the housing. Remember not to audition immediately, but come back in two days. Because vulcanized silica gel dries slowly.
When the film falls off, apply a little with 704 or fish bead glue until it sticks. Pay attention to flattening and flattening. Put it back for a day.
Add iron powder, dip the cotton swab in water, then dip it in iron powder, and then treat the membrane collapse.
Treatment method of voice coil disconnection
If the earphone is mute, just measure the wire. There is no conduction between the two solder joints behind the measuring unit. Make sure the voice coil is damaged. At present, most earplugs are generally led out from the side of the membrane. Although this will have a little impact on the sound quality, it greatly reduces the possibility of lead-out wire breakage. Even so, the unit rotation disconnection is often caused by human factors. During maintenance, you can lift the membrane with a blade, and then pick up the voice coil wire with a needle tip. Separate the two wires and pull them out in the opposite direction of winding. Be very careful when applying force. Pay attention to the different directions of the two lines. If you can't pull it, don't pull it hard, but use a thin earphone line to extend the voice coil line. It is best to have a magnifying glass to assist wiring. Tin is plated on the wire first, and then the wire is welded with a pointed soldering iron. And glue the wire to the earphone film with 704 glue. Then paste the earphone film, and weld the two lead-out voice coil wires to the solder joints on the back. It is best to protect the wire behind the bracket with hot sol to prevent it from being rubbed off again. Generally, headphones with copper rings will have higher repair success rate and less impact on sound quality.
All right! That's all for iron triangle maintenance. A good brand not only has good product quality, but also has good after-sales maintenance service. When you go out with this cool headset, the return rate must be very high! Rabbits also started with iron triangle headphones. The big red headphones are very eye-catching. This earphone can well isolate the noisy sound from the outside world, and you can immerse yourself in your own music world no matter where you are. Well done!
