Speaker daily maintenance and maintenance guide

2021-03-30 106
Speakers are indeed a kind of equipment that is not prone to failure, but not necessarily failure does not mean that it will not fail. In the process of using speakers and headphones, there will always be problems of one kind or another, which brings us great inconvenience. As the saying goes, take precautions. If you can do a good job of daily maintenance and maintenance during the use of speakers and headphones, you can at least delay the failure of speakers and headphones, and make your use more comfortable.

1. Dust prevention is the key
Dust has always been the natural enemy of computers. Many computers have often overlooked the huge lethality brought by dust in the course of many years of use. However, this will happen sooner or later. Many friends will ask the speaker is a closed design, how can dust enter the cabinet? I have to say that this is actually not a comprehensive understanding.
Although the speakers have adopted a sealed design, some brands of speakers with independent subwoofers have a connection cable between the satellite box and the subwoofer, which is clamped on by the pins on the cabinet. 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 also something that many friends have encountered.
Although the speaker is a sealed structure, the inside is not completely free from dust. When dust enters the cabinet, the most difficult to clean is the speaker unit. A little attention will cause the speaker to break. It is necessary to pay attention to cleaning. of. When cleaning the inside, the power should be turned off, and it should not be washed with water. It is better to use a vacuum cleaner, as long as it is gently washed on the speaker, most of the dust can be removed. Therefore, in daily life, we should clean the speakers at least once a week, and try to keep the speakers free from dust. In addition, try to place the speaker in a place where there is not much dust to prolong the life of the speaker.

2. Moisture-proof must be done well
Humidity is the greater natural enemy of speakers, and of course it is also the natural enemy of all electrical products. If the speaker is wet, the horn's diaphragm will physically deteriorate during the vibration, which will accelerate the aging of the horn's diaphragm and directly lead to the degradation of sound quality. It is like a piece of paper. The paper will be intact if it shakes when it is dry, but if it is dampened with water, the vibration will cause the paper to break or wrinkle.
In addition, humidity will aggravate the aging and breakage of the soft rubber ring of the speaker, and it can also corrode and rust some metal parts inside the speaker, causing unexpected failures. Therefore, when using speakers, you should place the speakers in a relatively dry environment. If the home environment is really humid, you can also make a big bag. Put the speakers in the bag when you are not using them. This will help The speaker is moisture-proof. In addition, the speaker should be kept playing for a period of time every day to prevent moisture from the heat emitted by the speaker itself.

3. The temperature of the speaker environment should be suitable

Various components and other parts in the sound box have certain requirements for temperature, such as wood, paper cone sound cone, high pitch silk film, suspension edge, centering bracket, adhesive, voice coil, etc. If the temperature is too high or too low, it will cause unstable operation of the speaker components. Of course, this problem will not occur under normal circumstances. However, some families have stoves, heating, etc. Try not to let the speakers close to such places. For example, in a heated room in the north, if the speakers are too close to the heater, it is really not good. This is worth noting.

4. The placement of speakers
Many friends see the speaker placement problem, they must raise objections, do I still need to find a place for the speaker placement? Can it be placed directly on the computer desk? In fact, the speaker placement is quite knowledgeable, of course, this is considered in terms of sound quality. Since this article mainly introduces the maintenance of speakers, I will not explain the specific method of placing speakers for the sake of sound quality. I just want to make two points. First, when placing speakers, try not to expose them to direct sunlight or Near a place 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, the speaker is not suitable to be placed in a place with strong electromagnetic fields, such as next to a refrigerator. Although they will not cause particularly serious consequences to the speakers, but after long-term use, there will be some unexpected failures. If you want to place it in a better place, you can consider a place with better ventilation, which is more conducive to the heat dissipation of the speaker.

5. Turn the speaker on and off, adjust the volume to a suitable position
At present, most speakers are active speakers. Except for a few speakers with independent power amplifiers, many speakers have built-in power amplifiers. The power amplifier chip is most afraid of the impact of instantaneous current. If the instantaneous current is very large, it is easy to create a successful amplifier chip and be burned. Therefore, before turning on the audio source device, adjust the sound of the speakers to a low level, and then increase the volume after the audio source device is activated. When turning off the audio source, you should also adjust the volume of the speakers to a low level before turning off the audio source. In this way, the power amplifier chip inside the speaker can be well protected, making your speaker "life" more enjoyable.

6. Don't listen to music at a louder volume for a long time
It is rare in real life to enjoy music at a louder volume when using speakers. However, this situation may also occur. For example, the computer is placed in the study room, and the speakers are also placed in the study room. When some friends come to chat and drink in the living room, the volume of the speakers in the study room will be adjusted very loudly, which is convenient for enjoying music in the living room.
What are the consequences of this? In terms of sound quality, it is easy to cause sound distortion, or even burn the pronunciation unit. In addition to this situation, it is easy to cause the temperature on the back of the speaker to be too high, which affects the service life of the speaker. Therefore, when using speakers, adjust the volume to about half at most, so that the above situation will not occur.
If the speaker is not used for a long time, it should be unplugged, because although there is no sound signal input to the speaker after the computer is turned off, the speaker is still working at a static working point, and there is still a quiescent current flowing through the internal circuit. It works, which means it is very likely to cause damage to amplifiers and other components.

7. Do not aim the microphone at the speaker
I believe this situation is more common. For example, when singing in some KTVs, if you use the microphone to aim at the speaker, it will make a harsh howling. This situation is caused by the tweeter of the speaker, and it is very easy to burn the tweeter. So when using the microphone, do not aim it at the speaker.

8. The speaker can be fixed better
The fixation mentioned here does not mean permanent fixation, which cannot be moved after fixation. The fixation we are referring to can be understood as preventing the speaker from slipping and moving, because it is inevitable that we will not touch the speaker when using the computer. If the speaker falls on the ground with minor injuries, it will be very troublesome for serious injuries. So you can use double-sided tape and other things to fix the speaker slightly.

9. After using for a long time, you should clean the speaker wire
After the speaker cable has been used for a long time, the two ends of the cable will inevitably be oxidized. When the end of the thread is oxidized, it will cause the sound quality of the speaker to decrease. At this time, it is necessary to clean the contact points with detergent to keep the sound quality unchanged for a long time.

10. When listening to music, check the line connection first
In fact, when the speaker cables are successfully connected, we will not touch these cables again. But don't be afraid of 10,000, but just in case, when using speakers, it is better to check whether the speaker cable is connected properly, or check whether the speaker cable has become a rat's dish.

Written at the end:
It can be seen that these simple maintenance and maintenance of the speakers are things that everyone can do, and it is not a big problem, such as damage to the box body and the welding circuit, etc., everyone can do it, but everyone usually pays attention to it. Pay attention to the problem. I have to admit that paying attention to the details of these maintenance and maintenance will greatly enhance the service life of our speakers. A set of speakers is not like a consumable digital electronic product. The more you listen to the sound, the more mature it is. The most critical problem is that we First of all, it needs to have a meticulous care.
