We repair headphones
Stop playing in one ear? It began to rustle? Wait throw out, repair!
')
The following are typical headphone faults. In 99% of cases, one of the options is yours.
Manifestations: the sound begins to rustle in one of the headphones (less often in both), eventually disappears completely.
Diagnosis: Breakage occurs at the bend of the cord, i.e. or directly at the connector, or at the input of the wire in the earpiece itself. You can accurately set the location if you turn on playback and rotate the cord. A crack or a sound indicates the exact location of the cliff.
Repair: Cut the cord below the break and re-solder it.
The plugs are usually of two types - solid plastic flexible, molded hard core and soft rubber cap. It is necessary to remove the rubber cap, if it is impossible - cut it with a knife.
Casting cut nippers, and get to the place of soldering wires to the metal contacts of the connector. Strip and solder the wire, and collect everything back.
Cavities, due to the removed plastic parts, should be filled with epoxy glue, better fast curing.
Cut the gum can be strengthened bondage of synthetic thread. Shrinkable tubing can also give a good result.
Need to disassemble the earpiece. Large headphones have an assembly on the screws. Smaller headphones - snaps on. Headphones droplets, earbuds - adhesive bonding. The glue joint is disassembled either with the help of a knife, or by squeezing the headphones in yews - due to the elastic bending, the crack usually goes along the glued joint.
The wire inside the headphone is tied in a knot to prevent it from being pulled out. Wire cut, clean, tie a knot and solder as it was. Headphone glue back.
This malfunction is possible only with headphones-plugs closed acoustic performance. The membrane is separated from the channel with a thin metal mesh. Earwax, as you use the earphone, covers this mesh and interferes with the passage of acoustic waves.
Diagnosis: the lack of sound despite the fact that the dial indicates the integrity of the windings of the headphones.
Repair: earphone disassemble and wash the mesh in alcohol. Disassembly is preferred so as not to stain the membrane with leaking alcohol and dirt particles.
Manifestations: crackling, rattling in one of the headphones, the difference in timbre of playback.
Diagnosis: visual inspection and opening of the earpiece.
Repair: after opening, straighten membrane if wrinkled. The effect will be temporary, headphones will need to be replaced. If there are foreign particles on the membrane, remove it. Rinse the mesh separating the membrane from the surrounding space.
Look at the photo of the place of the cliff lived:
With a small bend radius, the cores accumulate a large fatigue load and break. If you take a paper clip, straighten it and bend it in the middle, then one way, then the other, then after a few such bends it will break. The same thing happens with the conductors in the wire.
Struggling with this in two ways. For the first it is a special wire with a special weaving veins. The central channel of synthetic yarns provides the wire with tensile strength, and the strands wound in a spiral when bending the wires experience more torsional stress than bending. When the load on the torsion vein is more stable. The second way is to increase the bend radius. To do this, the connector or earpiece ends with an openwork flexible plastic construction, which, bending along with the wire, increases the bend radius. But it is strictly necessary to properly select the stiffness of the plastic, with the rhyme of hard or too soft plastic there will be no sense from the design.

Inner cliff lived in the cord
Manifestations: the sound begins to rustle in one of the headphones (less often in both), eventually disappears completely.
Diagnosis: Breakage occurs at the bend of the cord, i.e. or directly at the connector, or at the input of the wire in the earpiece itself. You can accurately set the location if you turn on playback and rotate the cord. A crack or a sound indicates the exact location of the cliff.

Option with a breakage at the connector
The plugs are usually of two types - solid plastic flexible, molded hard core and soft rubber cap. It is necessary to remove the rubber cap, if it is impossible - cut it with a knife.
Casting cut nippers, and get to the place of soldering wires to the metal contacts of the connector. Strip and solder the wire, and collect everything back.

Option with a cliff at the headset

Channel blockage
This malfunction is possible only with headphones-plugs closed acoustic performance. The membrane is separated from the channel with a thin metal mesh. Earwax, as you use the earphone, covers this mesh and interferes with the passage of acoustic waves.
Diagnosis: the lack of sound despite the fact that the dial indicates the integrity of the windings of the headphones.

Membrane damage
Manifestations: crackling, rattling in one of the headphones, the difference in timbre of playback.
Diagnosis: visual inspection and opening of the earpiece.
Repair: after opening, straighten membrane if wrinkled. The effect will be temporary, headphones will need to be replaced. If there are foreign particles on the membrane, remove it. Rinse the mesh separating the membrane from the surrounding space.
