How do I clean the microphone in my phone?

A modern person experiences discomfort if he does not have a mobile device at hand. But constant contact with technology obliges us to understand some things from scratch. This means that if you want to use modern technologies, you need to be prepared for all unforeseen situations. Devays need constant maintenance, and sometimes even in repair, which is easier to carry out independently, than to give any amount for the correction of minor malfunctions in the service center. There is one problem that most users have already experienced - it is the unstable work of the microphone, which is built into the mobile phone. It may be necessary to repair this component or to clean it for troubleshooting. Today we will learn how to clean the microphone in the phone.

The main causes of breakdowns of

There are three most common problems that can disable the sound recorder. Careful consideration of each of them will help to solve the problem by own efforts.

Contamination

Accumulation of dust, skin particles, small debris can get on the sound-sensitive head of the microphone, which leads to the loss of its useful properties. To fix this, you need to get cotton, alcohol and a screwdriver:

• Disassemble the phone, or rather its body, and remove the microphone.
• Now dip the cotton in alcohol, the main thing is not to overdo it.
• Use gentle movements to clean all dirty deposits from the sound-sensitive head.

Important! Carefully ensure that particles of cotton wool do not remain on the surface of the devices.

• Now, wait until the alcohol evaporates completely and return the microphone to its place, tightly screwing all the screws.

Exposure to moisture

Often, condensation accumulates between the gaskets of the microphone and its head. The head itself is not subject to corrosion, but moisture still does its job. Again, you need to disassemble the housing, release the head and put it to warm up under the incandescent lamp.

Important! Excellent with this will cope with the usual table lamp. If the device is equipped with gaskets, then the same actions should be performed above them.

Broken wiring contacts

Another reason for the failure of the device is a break in the incoming wire. There are two options for restoration work for this case: replacement and soldering. Choose one of them is necessary, focusing on a specific situation:

• The best option is to use a soldering iron for repairing a broken wire.
• But if the headphone wire has gaps in several places, it's better to replace everything at once.

How to repair a microphone? If the problem with it is more serious than the above, then the entire site should be replaced, especially if it is a smartphone. But if serious problems with the headset, it is better to just buy a new one.

Diagnostics

In order to find out if the device is working, it is necessary to acquire a multimeter or an analog tester, in which an ohmmeter is built. Disassemble the phone case, remove the microphone from it and ring it with an ohmmeter.

Important! A good microphone should ring similarly to a diode in one direction, and in another - the measuring device should show somewhere 20 kOhm. If the values ​​on the device are different from the nominal values, the component is defective and will need to be replaced.

Repair Instructions

First you need to determine the exact cause of the failure, and indeed the type of failure. The most common complaints usually occur on the following things:

• The microphone stopped working.
• The sensitivity of the microphone has decreased.

If you do take care of the recovery procedure yourself, then:

• First check if the device is properly connected to the phone. Probably, integrity of a wire is broken, then it is necessary to work with a soldering iron.
• If the microphone does not work and after that, you should get it out of the case and disassemble it. Check for non-integrity of all of its contacts, you may need something to twist or fix, in order to return the device to life.

Replacing the microphone

To replace the old microphone with a new one, follow the following instructions:

• Unplug the old broken microphone using a soldering iron and a blade. If you look at the whole structure from the side, you can notice the soldering of the contacts, which must be warmed up.
• Now you need to shove a flat blade under the microphone, while warming up all the legs. Then we simply separate the microphone from the chip, without applying any special efforts.
• Inspect the microcircuit for dirt, clean it with alcohol-containing liquid and remove the "remnants" of the microphone. Now you need to prepare the pad on the chip, in order to install a new microphone.
• Using a soldering iron and solder, we put the microphone on a vacant pad. If necessary, then you can use old wires.
• Now it is necessary to slightly press the sound recording device to the board and solder the wires sticking to all sides to the pads.

Important! The soldering should be done quickly, in order to avoid overheating.

• We remove the surplus of consumables and check the device for operability.

Congratulations! Now you know how to repair a microphone at home and at no extra cost.
