How to deal with the noise in the stereo and how to maintain it?

The noise in the stereo is a very annoying thing. We may have met in our lives. In fact, the maintenance of the sound is the key ~

The cause of noise in sound

There is noise in the speaker.

It is caused by many faults, the most typical of which is the leakage of the main casing, and the connecting wire itself is not plugged properly, so noise will be generated. A large part of the problems caused by the noise of speakers are caused by the damage of satellite speakers or sub-boxes. This failure may be caused by the amplifier circuit of the speaker or the speaker itself.

File quality: Nowadays, online music is very popular, and many songs are downloaded from the Internet, which is very convenient to use. However, it is precisely because of this open platform that the quality of documents is mixed.

The noise of sound is mainly the sampling ability without interference, which is embodied in the choice of microphone and sound card.

Power supply problem may cause current noise. Problems with the sound card; The problem of software setting; Network problems.

Incorrect line input: whether it is 2. 1 speaker or 2.0 speaker,

There is a connecting line from the sound source to the speaker, that is, the signal line for line input. If this signal line is not connected properly, it is likely to produce noise. Causes of mobile phone interference: If your speaker has noise only under special circumstances, it can almost be judged that it is a problem of mobile phone interference: the speaker works normally most of the time, and when a phone call or text message comes in, the speaker will have regular noise, resulting in abnormal use.

What if there is noise in the stereo?

If the noise is caused by a sound source, then let's try another sound source directly and eliminate the cause of the noise problem by elimination. The sound source mentioned here is a general term, that is, players, songs, musical instruments and so on.

If the horn burns out, we can listen carefully to which horn it is, open it after confirmation and take it out. There's a sound on the horn, which means it's not broken, and we can fix it. The easiest way is to drop the vegetable oil from home into the horn copper ring, and then slowly do it several times with its range until it feels smooth, and then put it on later, and it will return to its previous feeling. But don't remove the speaker, just drop it, or your stereo will be worse.

Use headphones. You must use the speaker. Be careful not to aim the speaker at the microphone. See if there is anything with magnetic field and sound wave around you. Put an electric appliance with a magnetic field. Is there something wrong with your sound card or microphone? Record a segment in the internal playback state.

According to the situation, please ask professionals to clean or debug for you. If you are downloading,

Due to network or other reasons, data is lost and files are incomplete. Will cause discomfort in use. In addition, improper installation of plug-ins can also lead to exceptions. I suggest that you reinstall according to my method: after you turn off your computer, uninstall it on the console and then download and install it. If the problem is caused by wiring, then we should consider changing the wiring first, but we don't know if it is a wiring problem yet, so we can try to repair it. Check the wiring to see if it is damaged. If so, reconnect and re-record. If not, then we have to check the connector, which is easy to cause problems. If it is a plastic rubber connector, then we have to change the wiring, which is not ideal. If it is metal, we can repair it ourselves, and then test the effect one by one after repair.

Matters needing attention in audio maintenance

1. dustproof is the key.

Dust has always been the natural enemy of computers, and many computers have been used for several years.

The great lethality caused by dust is often overlooked, but it will happen sooner or later. Many friends will ask, the speakers are all closed design, so how can dust enter the box? I have to say that this is actually an incomplete understanding. Although the speakers are sealed, some brands of speakers have independent subwoofers, and the cable between the satellite box and the subwoofer is clamped by the clamping feet on the box. If a lot of dust enters here, it will cause the connection between the speaker cable and the speaker to be unsmooth, which will directly affect the sound quality of the playback. I believe this is something that many friends have encountered.

Although the speaker has a sealed structure, it is not completely dust-free The speaker unit is the most difficult to clean when dust enters the box. If you are not careful, the speaker will break down, so it is necessary to pay attention when cleaning. When cleaning the interior, turn off the power supply and do not rinse with water. It's best to use a vacuum cleaner. You can remove most of the dust by washing it gently on the speaker.

So in our daily life, we should clean the speakers at least once a week and try to keep them away from dust. In addition, try to put the speaker in a place with less dust to prolong the life of the speaker.

2. moistureproof should be done well

Humidity is the biggest natural enemy of speakers, and of course it is also the natural enemy of all electrical products. If the speaker is damp, the physical degradation of the speaker diaphragm will occur during vibration, which will accelerate the aging of the speaker diaphragm and directly lead to the decline of sound quality. Just like a piece of paper, the vibration of the paper will be intact under dry conditions, but a slightly larger vibration force will make the paper crack or fold after being wetted with water.

In addition, humidity will aggravate the aging and damage of the soft rubber ring of the speaker, and at the same time, some metal parts inside the speaker will corrode and rust, causing unexpected failures. So when using the speaker, put the speaker in a relatively dry environment. If the home environment is really humid, you can also make a big bag, and put the speaker in the bag when not in use, which will help the speaker to be moisture-proof. In addition, the speaker should be kept playing for a period of time every day, and the heat emitted by the speaker itself should be used to prevent moisture.

3. The temperature of the speaker environment should be appropriate.

Various components and other parts in the speaker have certain temperature requirements, such as wood, paper basin, high-pitched silk membrane, hanging edge, centering bracket, adhesive, voice coil and so on. If the temperature is too high or too low, the speaker assembly will work unsteadily. Of course, this problem will not occur under normal circumstances. However, some families have stoves, heating and so on. Try not to let the speaker near such a place. For example, in a room with heating in the north, it is really bad that the speakers are too close to the heating, which is very noteworthy.

4. The location of the speaker

Many friends will definitely raise objections when they see the placement of speakers. Do you still need to find a place to put the speakers? Why don't you put it on the computer desk? In fact, the placement of speakers is quite learned, of course, this is considered from the aspect of sound quality. Because this article mainly introduces the maintenance of speakers, so for the sake of sound quality, I won't explain the specific placement method of speakers here. I just want to make two points. First, when placing speakers, I try not to put them in direct sunlight or near places where the temperature is too low. Because these places are particularly easy to cause the aging of the internal components of the speaker, it must be remembered.

In addition, speakers are not suitable for places with strong electromagnetic fields, such as the refrigerator. Although it will not cause particularly serious consequences to the speaker, after long-term use, there will be some unexpected failures. If you want to put it in a better place, you can consider a well-ventilated position, which is more conducive to the heat dissipation of the speaker.

It is quite necessary to pay attention when cleaning. When cleaning the interior, turn off the power supply and do not rinse with water. It's best to use a vacuum cleaner. You can remove most of the dust by washing it gently on the speaker.
