Any, even quite expensive headphones - veryshort-lived accessory. But if you began to knock up one earpiece, you accidentally tore the wire or broke off the plug - this is not an excuse to throw the headset into the trash.
Diagnosis of the problem
Before you can solder headphones, you need tounderstand what is the cause of the problem. The most probable cause is the mechanical thinning of the wires inside the cable. As a rule, this is the place of their connection to the earpiece or a plug. In some cases, the reason may be a break in the conductors as a result of a strong pinch, impact, etc.
Determine which earphone wire is damaged,it's easy - he usually does not talk, or the sound comes out of him with characteristic wheezing. For diagnostics, you can slightly shake the main cable. Look for malfunctions gradually, from the earpiece to the plug. The place of the fracture is felt by bending the wire around the big finger 90 degrees. If, with such a diagnosis, the sound is miraculously restored, then it will be necessary to replace the plug.
The damage site (if not explicitly) is detected with a 50% probability when analyzing the connection between the earpiece and the wire and the confidence in determining the faulty channel.
What is needed to repair
Just before you wire the headphones, check for the availability of the following tools and materials:
- solder;
- soldering device;
- rosin;
- technical knife;
- tablets of aspirin (acetylsalicylic acid) - fit even overdue.
How to solder headphones correctly
Let's consider the first effective way:
- To be reinsured, cut 1-3 cm more cable than it includes a problem area.
- The desired channel is in color. Common - blue or yellow, sometimes just copper, without insulation. The right channel is green, the left channel is red.
- Remove insulation - more than 0.5 cm from the endcable. Polymer is easily and neatly removed by a construction knife. If it is lacquer or paint, then a soldering iron is required. You can also clean it up with a knife.
- The next point is the tinning of the ends with solder. Heat the soldering iron, take the tip of its "sting" a small piece of solder.
- Set the ends of the wires to rosin and distribute the solder all over their surface with an even layer. Wires are ready for soldering.
If you want to combine the delete procedurelacquer insulation and tinning, then you will need an aspirin tablet. I would like to warn that such repairs should be carried out in a ventilated room, try not to inhale the smoke. Put the wire on the tablet, then operate with a soldering iron with a fat droplet of rosin. This combination removes the coating from the varnish.
The second method of soldering
The second way, which tells how to solder headphones with the tinning of the wires with a sandpaper:
- Grains of sandpaper should not be particularly large. The material itself will need a small piece.
- On the material, apply a little rosin, then place the postings on it.
- Warm it properly with a soldering iron, pull it out. The varnish on the wire will soften.
- Repeat the procedure with stretching until the insulation is completely scraped off.
- After repair, insulate the area with heat shrinkage or electrical tape.
Some remove the insulation with the light of a cigarette lighter, then remove the carbon with alcohol and flux.
Repair of the plug
How to solder the bitten wires from the headphones, we dismantled. The soldering of the plug is made according to a similar scheme having its own characteristics.
To get started, check out the connection diagram for regular headphones.
How to solder the headphone plug:
- Cut off the idle plug, with wiringfollow the same steps as described above. It is important to bare their minimum areas (2-3 mm), since contact of bare wires in operation can lead to a short circuit.
- Insert the new plug through the headphone base.
- The connecting points on the plug are slightly scratched for easier soldering. In places where the cable is connected, they should also be irradiated.
- First, connect "ground" (copper wire), then left (white) and right (red) channels.
- Protect the area with electrical tape. To ensure that the ration is not accidentally disturbed, in the immediate vicinity of the isolated area, tie a bundle on the wiring.
- Close the area with the body.
And this scheme is useful to those who repair headphones, equipped with a microphone (headset).
How to solder headphones with a microphone? By the same algorithm, only connect to the plug will have four wires instead of three.
Unsatisfactory result of repair of the plug
If during testing you noticed that the speaker of one of the headphones keeps silent, the cause of the problem can be that:
- poorly welded joints;
- trouble with earpiece dynamics - the probability of a wire break directly near it is great;
- problem in the body of the cable.
At the first problem the process of soldering will have to be repeated, at the last one - refer to the instructions at the beginning of the article (on repair of broken wires). How to solder headphones with the second problem:
- Cut the wire next to the inactive earphone.
- Disassemble the earpiece - the self-locking design will easily allow it to be done.
- Strip, zaludite postings.
- Solder earphone wiring to cable body wiring, test, assemble into original form.
With a soldering iron and elementary skillswork with him, the procedure for fixing the headphones is quite understandable and simple. Diagnosis of the problem also does not cause difficulties. The main reason is the mechanical damage to the wires in the body of the cable or in connection with the headphones and plug. We will be glad if this article helped you to return your headset to working condition.
