What should I do if there is a noise in the stereo, and what causes it?

The sound has a sizzling noise, which is caused by the overall shielding of the audio. Nowadays, there are many electronic transformer circuits used in electrical appliances, and this kind of circuit is easy to produce high-frequency oscillation interference signals, such as chargers and energy-saving lamps.

Wait. The sound interference is very large, if the audio anti-interference signal is not good, it is easy to sizzle sound.

So how to solve this phenomenon, the solution is as follows:

1. First of all, check the ** of the sound, which belongs to the electronic components in the audio.

or the problem of external interference.

2. Look at the electronic components on the circuit board for blackening, burning, expansion, and leakage, and if so, you need to replace the same type of components.

3. Check whether the grounding wire of the circuit board is off, and the audio shell should also be grounded at the same time as the shielding shell of the whole machine.

4. There is an industrial area away from the residential area, and the interference signal generated is power interference, which cannot be ruled out.

5. Try to change the power plug upside down.

6. If it really doesn't work, add an anti-interference circuit at the input end of the power transformer, circuit diagram.

As follows: <>

There are many reasons, and the first thing to do is to find out the cause before it can be solved and eliminated.

For example, if the audio cable is aging or the plug and socket are in poor contact, you can plug it in again, or replace a pair of audio cables to see how it goes.

The power amplifier circuit board is poorly grounded, and the connector is loose, or it is caused by the desoldering of the solder legs.

Abnormal performance of the filter capacitor or leakage of the bulge, damage to a certain component, etc.

How to deal with the noise of the audio:1. The quality of the sound source needs to be checked and the high-quality sound source replaced to solve the problem.

2. To produce a sound of sizzling, it is necessary to check whether the connection line is in good contact and check the integrity of the connecting line.

3. The sound may be that the capacitor of the power amplifier is bulging and needs to be replaced.

4. The sound may come from the interference of the surrounding signal, and the signal shielding needs to be done.

Summary: First of all, it is necessary to confirm whether the noise is a factor of the speaker itself, if it is indeed the cause of the sound itself, there is no need to worry, generally speaking, it is because the speaker is burned. After judging which side of the speaker has a problem, take it apart and check it, and if it can still be said that there is still help.

Take a few drops of cooking oil at home and drop it in the speaker, listen to the sound of **, gently squeeze and then release, repeat many times until it feels smooth. Be careful not to drip too much, too much oil will only damage the speaker.

Summary. Hello, glad to answer for you. <>

The solution to the noise of the sound is as follows:1Check the speaker connection:

First of all, you need to check whether the connection of the speaker is secure. Often, due to poor connection, the speaker will be noisy. Check whether the speaker's power supply, volume control, signal cable, etc. are plugged in and the plug is clean.

If the plug is bad, you can gently wipe it with an eraser and plug it back in. 2.Change speaker position:

If the speaker is too close to other electronic devices, it can cause interference, causing noise. At this point, the speaker position needs to be moved away from other electronic devices to reduce interference. 3.

Adjust the volume of your speaker: A loud or low volume of your speaker can produce noise. First of all, you need to adjust the volume to a suitable level.

If the volume is too loud, you can lower the volume, and if the volume is too low, you can increase the volume. <>

4.Replace speaker cables: Aging speaker wires can also cause noise.

If the speaker cable has been used for too long, you can consider replacing it with a better quality speaker cable. 5.Check the sound source:

Loudspeaker noise can also be caused by a problem with the source itself. You can try changing the sound source, such as using a different device or other ****, to see if there is still noise. 6.

Check the speaker itself: If none of the above methods solve the problem, you can consider checking the speaker itself for faults. The speaker can be taken apart to check for loose parts or damaged parts inside.

Dear, there are still questions to be raised, here continue to answer <> for you

Summary. Hello, dear, the reasons for the noise in the stereo are as follows.

What should I do if there is a noise in the stereo, and what causes it?

Hello, dear, the reasons for the noise in the stereo are as follows.

First of all, it is necessary to confirm whether the noise is a factor of the sound itself, if it is indeed the reason for the sound itself, there is no need to worry, generally speaking, it is because the speaker of the Horn Digging Bureau is burned. After judging which side of the wax skin has a problem with the audio, open it to check, and if it can still be saved, it can be saved. Take a few drops of cooking oil at home and drop it in the speaker, listen to the sound of **, gently squeeze and then loosen it, repeat many times until it feels smooth.

Be careful not to drip too much, too much oil will only damage the speaker.

It is also possible that Huaiju is caused by poor line contact, although there is no way to be 100% sure, but you will not make a mistake if you try. The simplest case of the line is that it is broken, and we just need to fix it; If there is a problem with the internal lead burner, it is still useless if it is inserted into other equipment, so it can only be replaced.

I have a landscape 15 inch trolley stereo card squeaks when singing?

If the computer is not properly set up to cause noise, we can open the control panel, select the hardware column, and select the advanced collapse settings of the audio manager. Do manual debugging.

The interference of the magnetic field may also lead to the generation of noise, and the mobile phone is too close to the sound and the sound is missing, which may not only damage the audio, but also the quality of the mobile phone itself may be affected. We can remove hail products that are prone to magnetic fields, such as mobile phones.

Kiss, the reason why the landscape 15-inch trolley audio card squeaks when singing is as above.

It is recommended to check in turn.

Some say that the reverberation is turned on, is there a problem with this?

There is no such squeak when you put the USB disk.,It's just that the card song has a squeak.。

Hello, dear, the reverberation is turned on and will not be affected, unless there is a problem with the loudspeaker.

Kiss,There's no such squeak when you put the USB disk.,It's just that the card song has a squeak or the above reasons.。

It is recommended to check it.

Ok thanks.

You're welcome, kiss.

What should I do if there is a noise in the stereo, and what causes it?

Hello, what should I do if there is a noise in the stereo, what is the reason for it? Interference, poor contact, poor quality of the speaker itself, etc. 1.

Power transformer interference is caused by magnetic flux leakage from the power supply. Magnetic flux leakage can be blocked by an anti-interference magnetic ring made of modified iron raw materials for transformers, and external transformers can also be used. Stray radio waves affect the computer host, audio transmission wires, crossovers, wireless network equipment may become audio interference signals, in the case of allowable conditions, the chassis should be avoided as much as possible on the computer host, mobile phones and other electronic products.

2.For mechanical noise, a rubber damping layer can be added between the transformer and the fixing plate. The grounding device of each original code tremor shell must be grounded, and the audio input line must be shielded with a cable.

The audio speaker has a "hissing" sound, and most of the things like this are caused by the overall shielding of the fiber, or the first stage of the power transformer winding resistance is not well protected, you can try the power cord plug off the block. 3.The accumulation and damage of dust between the metal material brush and the diaphragm of the thermal noise potentiometer can lead to poor contact and pure imitation, which in turn produces noise.

If the screws are not tightened and the inverted tube is unqualified, it will also cause noise of mechanical equipment. Thermal dryness can be solved by dismantling low-noise components, reducing the load on component operation, and reducing operating temperature.
