What problems should be paid attention to when using speakers

As a person who likes music, there is more or less a speaker at home. However, sometimes it is found that various problems occur when the speaker is suddenly seen. Most of the problems are caused when we use the speaker, so what problems should be paid attention to when using the speaker? Today I will give you a brief introduction.

Note 1: For the newly purchased speakers, we have to run-in it like a new car, which is the "burning machine" in the speaker industry. Only after fully running-in, the speakers can play their potential. Since the "horn", an important part of the speaker, is the key component that determines the sound quality and service life of the speaker, and most of the speakers are composed of reinforced paper cones or bulletproof cloth. New speakers are generally stiff and require a softening process, so the speaker needs to be burned. It sounds better and more durable. Many people find that speakers need to be heated for a while to make them sound better. We agree, the only difference is that someone preached to use a loud volume to cook. This is wrong. In fact, the running-in between the speaker and the car is the same. Slowly running-in will make the mechanical part (the vibrating part is equivalent to the mechanical part) get the best running-in, and there is no benefit to the speaker at all. The circle may be deformed. Therefore, the simmering heat is good, otherwise the sound will be sharp, hoarse, broken, uneven and other problems. As for the specific method of burning the machine, please search for relevant knowledge on the Internet, and I will not repeat it here.

Note two when using the speaker: The problem of the place of use: any speaker is turned on to the maximum sound, there will be phenomena such as broken sound, so the volume can be turned up to 8 and it is almost the same. Originally, the power of this speaker is 40W. It is more than enough to use the space within 100 square meters. If you put it on a square or use it in a large classroom, its power must be unbearable.

Note 3: Prevent the sudden impact of large signals: Generally, there are the following situations: One is because the potentiometer switch is not turned to the lowest level after listening to the sound the last time, or the potentiometer is turned on by someone else by mistake. It is in a high volume state, causing a large signal impact. The second is that there are sudden large dynamic fragments in the music. In order to emphasize the contrast in these clips, the signals are mostly weak before the arrival of the big dynamics. At this time, if you are not mentally prepared, turn up the volume, it is easy to damage the speaker when a large dynamic signal comes. Such as explosions, drums, thunder and so on. The third situation is that when the speaker is working normally, the signal line and power cord are suddenly plugged in. At this time, a large current impact will occur, which is most likely to damage the speaker.

Note four when using the speaker: usually pay attention to standard operation: when listening to the sound, first check whether the wiring is correct and whether the position of the potentiometer is too large. When starting, shutting down, restarting, etc., the speaker volume should be turned off to a minimum or the power supply should be turned off to prevent large inrush current from damaging the speakers. When singing karaoke, keep away from the speaker as much as possible, and the microphone should not be pointed at the speaker to avoid howling or even burning the tweeter. At the same time, in order to protect the speakers, in general applications, the volume of the speakers should not be turned up too much, as long as it is enough, about 1/2 is fine, because in addition to the sound distortion problem, some big dynamic audiophiles are definitely speaker killers. Active speakers on the market, although the nominal power is very large (even exaggerated to a few hundred W), but that is not the actual power, generally tens of W is considered large. Therefore, when using it, do not work at high volume for a long time, otherwise it will easily damage the power supply and amplifier circuit. To prevent accidental collision and fall from the tripod, it is best to stick a few pieces of double-sided tape on the bottom of the box. When the speaker is used for a period of time, the terminal of the speaker cable will be more or less oxidized. This oxide film will greatly affect the contact state, which will reduce the sound quality. The user should clean the contact point with a detergent to maintain the best connection state .

Note 5 when using the speaker: Avoid using it in harsh environments: various parts of the speaker such as veneer, paper cone, tweeter film, suspension, centering bracket, adhesive, voice coil, etc. Most of them are more sensitive to changes in temperature and humidity. If the temperature is too low or too high, the stability of these parts will be affected. If the temperature is too low and less than 5 degrees Celsius, the overhang will easily become brittle. If the volume is turned on at this time, it will easily cause the overhang to break. If the temperature is too high and greater than 40 degrees Celsius, the voice coil will overheat, which will cause sound degradation. Therefore, the speakers should be avoided in places exposed to sunlight, near radiators, and places with sub-zero temperatures. The influence of humidity is also great. If it is too dry, the veneer outside the speaker will burst, and the thick wooden cabinet is prone to cracks. The solution is to purchase a humidifier or place a basin of clean water indoors. If the humidity is too high, the cone is prone to damp and mildew, the sound is weak, and the wiring is also easy to oxidize. The solution is to put some dehumidifiers and desiccants indoors. In addition, dustproof and clean speakers are also very important. When you are not listening to the speakers, it is best to add a dust cover. The surface of the speakers can be cleaned with a towel dipped in warm water and wrung out and wiped, but you must remember to wait until the water is completely dry before turning it on .

Note 6 when using the speaker: Pay attention to the location: First, the speaker should be placed in a location that avoids direct sunlight, and it is not suitable to place the speaker next to the radiator or in a place where the temperature is too low, otherwise it will cause the surface of the cabinet. Foaming or aging of electrical components, do not place the speaker in a damp place for a long time, so as not to make the voice coil rusty or moldy. In addition, do not place the speakers too close to the CRT monitor. Because the CRT monitor is too delicate, even if it is an antimagnetic speaker, it will also have a certain impact on the monitor. Similarly, the speakers should be kept away from strong magnetic fields. If the mobile phone is close to the speakers, the speakers will be noisy when a call comes in. Secondly, in order to save space, we often put the speakers under the computer desk or stack them together. This placement is extremely unscientific. Even the best sound card plus high-end speakers will not have good sound performance in this case. Not to mention the presence of sound field positioning. The correct method should be: symmetrical placement with the display as the center (take ordinary 2.1 speakers as an example). And ensure that the speaker is facing the user, and the position of the subwoofer can be more flexible due to the weak directivity. For speakers that often turn on loudly, it is best to use a floor stand. Do not put the speakers directly on the computer desk (especially the subwoofer), so as to avoid resonance with the computer desk and cause distortion.
