As often happens, that recently bought ear-phones begin to "knock". The sound in one of the headphones begins to be supplemented with wheezing, noise, and eventually can disappear altogether. Can I repair headphones or they need to be taken to a service center, or maybe it's time to buy new ones? At first you can try to fix them yourself.
How can I repair the headphones myself?
So, before we tell how to fix the headphones, if one of them ceases to work, we will list the necessary tools and materials for this.
If the headphones assume the presence of small cogs, you will need a screwdriver of the correct size. In addition, a clerk's knife and lighter is needed. You will probably need an electrical tape or epoxy adhesive to connect the broken wires. Connecting parts can also be a soldering iron and tubes with heat shrinkage. Also, a multimeter helps to find the place of the break.
So, how to fix headphones, if one does not work? Most often, a breakage occurs due to a rupture inside the cord or simply poor build quality. To eliminate these problems, special skills and knowledge will not be required. You need to first find out the exact place of the problem.
If the sound in the headphone is accompanied by noise and noise, and eventually the sound in it completely disappears, you need to walk around the cord with your fingers, connecting the headphones and turning on the sound. Especially carefully probe the folds and the area where the wire enters the earpiece. When you stumble upon a problem place, you will hear a characteristic sound.
Depending on where the breakdown occurs, your further actions can develop according to several scenarios. If the break is inside the headphone, you need to open it. If the earphone is on the screws, unwind them. Small headphones-droplets are often simply glued along the sides, so that they can be opened with the tip of an ordinary knife.
To determine the location of the gap in the open earpiece, walk on the cord and at this time listen to the sound. When you find a place, cut the wire below it, peel it to the wire and solder it to the previous connection point.
Many headphones inside are tied to a knot, so before you solder the wires, also tie them. Before assembling the headphones, check them again for sound. You can glue them back using epoxy glue.
If the reason that one ear does not work - in the breakage inside the plug, before you fix the headphones, you need to find the place of the cliff. Similarly, run your fingers along the wire and listen to the sound. When you find a problem place, you will need to get to the inner wire to cut it.
Pre-cut the plug from the rubber, find the place of connection of the connector and wire, cut off the non-working area and on the new secure with a soldering iron . Recover with an epoxy adhesive. You can also wrap the plug on top of the thread or put a thick plastic shell from another wire.
How to use a multimeter?
If you could not find a breakdown by probing and
Configure the multimeter in this way: set it to the conductivity check, insert the black probe into the hole marked COM, and red - into the hole marked with Ω, mA or))).
Test the wires with a multimeter: it will make a squeak in places where there are no gaps. Only applying it is necessary to wires without winding. You need to carefully remove it on two small sections - next to the plug and next to the headset. If the multimeter sings near the plug, then the problem is in the headset, and vice versa.
