We repair headphones by yourself

Sooner or later, each of us is faced with this situation: recently purchased regular headphones for a phone or MP 3-player broke again, and in the drawer of the table of such products is not one pair ... As a rule, in one instance of headphones the speakers fail, in the other - the cord is plugged near the connector, and, thus, there is an opportunity to make one but several working devices from several faulty devices. This process will be reflected in the proposed article.

Before us are three copies of the headphones. The first copy is fully functional and has not been in operation, but is not equipped with a TRS type connector (or, as they say, a mini-jack) and is an accessory of the headset with a built-in microphone. At the headphones located in the middle, the wire at the input of the connector is broken,in the latter, there is a problem with the speakers, but the cord is in order, based on this cord “new” headphones will be assembled.

With the help of thin and enough sharp knife open the headphone casing. Since in the described case there is no cover for one of the headphone cases besides faulty speakers, you will have to replace the cases themselves.

We cut off the faulty speakers and remove the insulation from wires, leaving bare ends about a centimeter long. We clean the wires and conductors (the length of the trimmed area can be within 2-3 mm). Using the tester, we again make sure that the cord is in good condition and find out which wire to solder the left and to which right speaker (if there are appropriate markings on the headphone housings). The common (bulk) wire of both channels is connected to a cylindrical contact located directly at the base of the connector body, the “+” of the right channel is connected to the middle contact,“+” Of the left channel - with end contact.

When selecting speakers from several headphones, you should keep in mind that the resistance of their coils should be the same, otherwise you are provided with discomfort due to different loudness of channels and differences in frequency characteristics. This parameter can be in the range of fifteen to 50-60 ohms - the resistance of the speakers shown in the photo, for example, is 41 ohms.

We put on the speaker casing wires. To prevent a break in the conductors when using headphones, we fix the wires in the hubs with nodes.

Solder the wires to the speakers. The polarity of the wire connection does not matter much, but the phasing must be observed necessarily, i.e. the bulk and signal wires on both speakers should be soldered in the same way.Failure to comply with this condition will lead to the fact that one speaker will “beat” forward, and the second - back, this will affect the sound quality is not the best way.
