What should I do if the speaker of the mobile phone comes in, it has already entered, the sound is n

In this case, it is necessary to judge the physical mobile phone after on-site inspection.

In order to understand and solve the problems of the mobile phone in a more targeted manner, it is recommended to send the mobile phone to the nearest service center for testing, and the service center will determine the specific problems, accessories, and whether the mobile phone is within the scope of repair and maintenance according to the test results**.

Please visit the Service Center page on Samsung's official website.

1. Magnetic field interference.

If there is a magnetic field generated by the passage of electric current near the environment of the call, it will also cause noise in the earpiece, in which case, avoiding these magnetic fields can solve the problem of earpiece noise.

2. Signal problems.

If the signal of the call environment is not good, it will cause a "zizzle" sound during the call, in this case, changing the call environment will naturally solve the problem.

3. Poor contact of the earpiece.

When our mobile phone accidentally dropped, it may cause the contact of the earpiece to loosen or desolder, which will cause the mobile phone earpiece to appear murmuring, in this regard, you can go to the repair shop to find someone to see, basically, as long as the loose place is welded on, it can be solved.

4. Circuit failure.

If there is a problem with the handset circuit of the mobile phone, there will also be noise when answering **, which also needs to be checked by the maintenance personnel, and the circuit can be solved after restoration.

To sum up, it is the main reason for the noise of the mobile phone earpiece, and it should be noted that the probability of failure of some copycat mobile phone handsets with rough quality and workmanship is also relatively high. At the same time, if your phone's earpiece doesn't make a lot of noise, it may be caused by a network problem.

Check whether there is any dust or dirt near the dust filter at the bottom of the speaker, and if so, clean it with a toothbrush or alcohol.

If it is not used to clean the horn, generally speaking, the horn is broken, and the horn is replaced.

1. The mobile phone speaker is an electroacoustic device that converts electrical energy into sound energy, which is simply a sound generator.

2. There are many types of speakers, although they work in different ways, but in the end, they all promote the surrounding air by generating mechanical vibration, so that the air medium fluctuates to achieve the conversion of "electricity-force-sound".

3. Features of mobile phone speaker: ultra-thin, light weight, small space occupation. The energy conversion efficiency is high, the consumption is high, and the speaker adopts a full-band design, which has the characteristics of wide directivity and low distortion.

It may be that the horn has gone in, iron filings, or impurities. You can return to the factory for repair, no money, but it takes a long time, about 7 working days, if you get it to the mobile phone store, you can repair it. It is not expensive, if it is about 20 yuan to clean

Changing the horn is not more than 30 yuan. However, if there is any quality problem in the future, the manufacturer will not warrant it.

You must be charging while playing with your mobile phone, and I'm like this too, but I can't go to the mobile phone store and ask him to help you take a look, and generally don't need money.

Take your phone to the store to get it repaired I don't know much about mobile phones.

1. Check whether the "Turn off all sounds" option is set: Menu - Settings - Accessibility - Turn off all sounds and cancel the checkmark.

Second, check whether the speaker is silent:

1. Dial ** to test whether the handset and the phone delivery are normal. If the speaker is likely to fail during the normal call test, it is recommended to send it for repair. 2. Use the original headset to test whether the **** is normal. If the headphones are used normally, the speaker is more likely to malfunction, and it is recommended to send it for repair.

3. Eliminate software conflicts: back up your mobile phone data (**book, short message, multi** files, etc.), and restore factory settings (function table - settings - reset - restore factory settings).

If the volume of the mobile phone's speaker is abnormal, it is recommended:

1.Restart the machine.

2.Eliminate third-party app interference, back up data (contacts, SMS, **, etc.), and factory reset attempts.

3.If the problem persists, it is recommended that you bring the purchase invoice, repair card and machine to the service center for professional after-sales engineers to help test.

3. Bluetooth reason: Set Bluetooth off. 4. Reason for mobile phone case:

Buy a certified phone case of the specified specification and model. 5. If the phone is running for a long time, try to turn off and restart the phone. It's all invalid, it's the hardware is broken, and I have to go to the repair shop to repair it.

Speaker speaker noise solution.

1. Try again with a file with good sound quality.

2. Restart the phone to see if the phone is running too slowly and causes broken sound and noise.

3. Reinstall the battery and back cover, especially if the back cover of the mobile phone is not put for the time being, and test the sound quality of the mobile phone speaker.

4. The speaker speaker enters the impurities and vibration diaphragm damage can only be sent for repair, usually the warranty period is 1 year, if it is not man-made damage, the speaker noise is within the scope of the after-sales warranty, and can be replaced free of charge.

Summary. Because your headphones and that speaker are not using the same module, they can't do it, and they don't affect each other.

If the sound of the speaker on your side is intermittent, then it may be that the line contact is not slow, the ex-brother seems to be broken, or there is a problem with a switch disturbance component, and you can go to the mobile phone store to repair it.

In this case, is it not that the speaker horn is broken.

I went to the repair shop and he said that the horn was not broken and it was not repaired.

It's not that the horn is broken, because if the horn is broken, there is no sound on your side, so it should be a problem with the line connecting the horn.

Well, is this situation easy to fix? Is it okay to fix the connecting cables?

When there is no sound, you can hear the sound by plugging in the headphones.

What's going on?

Because your headphones and that speaker are not using the same module, they can't do it, and they don't affect each other.

This kind of ** is not expensive, because the bad one is not a major component.
