Speaker manufacturers: 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 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 it is easy to have problems such as sharp, hoarse, crackling, and uneven sound. 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.
