Some common headset maintenance tips and methods

The headphone cable is broken, the headset line is hardened, the headphone cable is cracked, the shell is broken, the hole is blocked, and so on. The

1. Membrane collapse, membrane cracking, film shedding, iron powder treatment

General headphones are broken sound, noise, bass missing failure is generally considered to be caused by the above reasons. First of all, open the headphone case, is the first soft cover to take down the soft sleeve and then tip tweezers and other sharp tools a little bit to pick the iron net and steel cover, until the film all exposed. Hard shell can be a flat head with a small screwdriver in the joints at a circle, and then generally easy to open, and eventually make the film all exposed.

Membrane collapse, for the film collapse with a tweezers clamp a small piece of double-sided adhesive, gently place the film to stick up the place. Pay attention to the size of the intensity of control. After the membrane is restored, it can be replaced.

Membrane cracking, repair is unlikely, even if the repair sound quality will be damaged. But the success of the treatment, the sound quality damage less light. That is, with a needle dipped in a little 704 glue (also known as vulcanized silicone), coated at the cracks. Be careful not to be too thick to cover the cracks. Then install the shell. Remember not to try immediately, should be placed after two days to try again. Because vulcanized silica gel dry slower.

Film off, with 704 or fish beads coated with a little, can stick to. Pay attention to sticky compression. Replacement can be placed one day. Into the iron powder, with a cotton swab dipped in water after the iron powder stained, and then deal with membrane collapse.

2. Treatment of voice coil disconnection

If the headset is silent and the line finisher is good. The two solder joints behind the measuring unit do not turn on. The voice coil is broken. Now most of the earplugs are generally changed from the next lead, although the sound quality will have a little impact, but it makes the possibility of greatly reduced lead off the line. Although it is still often due to human factors to make the unit turn the line to break off. Maintenance can be used when a film to pull up the film, and then the voice coil with a needle to pick up. The two lines will be separated and then the direction of the wire along the opposite direction of the line pull out some of the force should be very cautious. Note that the direction of the two lines is certainly different. If you can not pull it, do not force to pull, and the application of a thin headset line will voice line extension. When the line is best equipped with magnifying glass auxiliary, first on the line tin, and then the tip of the soldering iron will be welded. And paste the line with 704 glue on the headset membrane. And then stick on the headset membrane, the lead out of the two voice coil welded in the back of the solder joints. It is best to use a hot sol to protect the back of the line to protect, to prevent further rub off. The general film above the copper ring repair success rate will be higher, the impact on the sound quality will be smaller.

3. headphone cable disconnection, headphone cable cracking treatment

Headphone disconnection generally occurs in the headset plug, the headset sub-line and headphone unit outlet and other parts.

Headphone plug, when the headset is in bad contact. There is a reaction at the plug that is broken here. Cut the headset line from here. And then stripped to find the broken parts of the line, the core cut neatly. Line a total of four were left channel, left channel, right channel, right channel, with color to be distinguished. For the plug is the three-pole left and right channel of the ground is connected together. Headphones outside the package with insulating paint, so the direct test is not measured with the table, should be given to the wire head tin. The specific method of operation is, first coated with rosin or solder paste on the line, and then dip with tin iron until the solder line will be infiltration. And then it is best to open the headset with the table to measure the four lines to check the other broken line. If the normal description of this only one break. And then the head of the ear head of the soft sleeve peeled off set on the line, the plug behind the hard plastic with a blade cut, exposed solder joints. And then the line one by one welding up. Generally two to welding in the thickest part of the right channel welding in the middle, left channel welding in the thinnest parts. Generally two yellow lines are ground, red line is the right channel, green line is the left channel. Of course there are exceptions, it is best to open the unit to measure it. After welding, check to prevent short circuit. And then try to plug in the machine. With their own familiar songs (to distinguish between the left and right channels of the song). If the anti, then it will change the left and right for the two lines (the middle and the thinnest on beats by dre studio the line), and then confirm the implementation of the band after the test. First with a white plastic tape bandage a few laps, the thickness should be able to plug into the soft sleeve. Pay attention to the line and the head bandaged together. Then glue the tape with 502 glue to make it stronger. At this point you can use the vise to wrap the cloth at the folder. And then painted in the above 704 plastic, into the soft can be. A good process can not see the whole move hands and feet. To be dry after the use of dry.

4. Headset line bifurcation disconnection method

And the plug at the same investigation method, when the headset does not ring when pushing this line when the intermittent. You can be sure that it is broken here. Is not a word, if it is accidentally pull bad, then do not do unnecessary trouble. Only cut the bad one of it can. If it is used for a long time that both are cut to deal with. Because for a long time one of the problems then the other is not far off. It is best to repair a thorough, from the opening line cut the headset line and then peel the line a little. Find the position of the broken line. Then put the heat shrink tubing on the broken line, and then screw the same color. And then coated with some rosin or solder paste, with a soldering iron soldering iron until the solder infiltration wire so far. With a little tape for insulation treatment. And then on both sides of the line coated with 502 sets of good heat shrink tube, with hot air xxx to blow or lighter to roast. After the shrinkage of the heat shrink tube 502 will break the two ends of the thread and heat shrink tube stick together. Even if it is hard to pull there is no relationship. For SONY that with a plastic tube can be hidden in the plastic box breakpoint, so completely do not see the scars.

5. Headphone unit outlet part of the treatment method

Remove the headphones (refer to the first part of the dismantling method), with a soldering iron from the unit to burn down. Draw some of the line to know the broken part of the line, the end of the cut. And then the line stripped a length. Tin plating on the wire head (tinned method refer to Part 3) and then welded to the unit. (Red, green or blue, etc.) connected to the location of the marked point, and the ground (usually yellow) is connected to the point where there is no point. After welding the test. Finally install the shell can be. This is often the way to make the original headphone cable shorter, the solution is to re-line from the bifurcation or remove the bifurcation of the knot and then pull down the line, with heat shrink tube or rope to knot again. Resulting in two lines can not be equal to the two lines are dealt with.

6. headphone cable cracking and the way to change the way the headset line can be used to deal with partial heat shrink tube, is to remove the headphone unit, first open the earphone shell, and then use the iron to iron down the line, you can easily put Headphone line out. Note that it is best to mark the left and right channels before extracting. And then cut a suitable heat shrink tube, set up. In the rupture of the place coated with a little 502 glue. And then baked with hot air xxx or lighter to heat shrink tube shrink on it. (Please refer to the previous paragraph for the method of disassembly and installation). I would like to say no more. I have a little bit of the way to pick up the wire. For different grades of headphones is best to choose different grades of wire.

High-end headphones with ordinary wire will limit the performance of the play, and low-end headphones with too high-end wire and can not improve the performance of how much, but also a little overkill is not economical. Low-grade headphones can choose the general oxygen-free copper wire, mid-range with a single crystal oxygen-free copper wire, the best high-grade crystal copper wire. General low-grade oxygen-free copper wire fake a lot, it is best to find the machine headset line for the better.

7. Damage of the shell and the handling of the plug hole

For the shell can be broken after opening the ear shell, washed with alcohol. And so on after drying with 502 glue good. So that the plastic can be completely dry after the back. Some people often easy to use the ear box will be sticky with 502 glue stick, in fact, this approach is not desirable. Because, one, 502 plastic permeability is very strong, easy to flow into the headset unit to damage; Second, 502 adhesive bond is too strong, to repair again caused by difficulties. It is recommended that you use 704 silicone and fish beads Wan Nengjiao, and to pay special attention to the amount.

8. For the headphone hole blockade recommendations we open the headset after the use of alcohol cleaning
