Precautions for using Bluetooth speakers
As a person who likes music, there is more or less a speaker at home. However, sometimes you will find that all kinds of problems occur when you see the speakers. Most of the problems are caused when we use the speakers. What problems should be paid attention to when using the speakers? Today I will give you a brief introduction.
Note one when using the speaker:
For newly purchased speakers, we have to run-in it like a new car, that is, the “burning machine” in the speaker industry. Only after fully running-in can the speakers 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 (vibration part equivalent to the mechanical part) get the best running-in. Crazy cooking will not benefit 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 sound is turned on to the loudest, there will be phenomena such as broken sound, so the volume of up to 8 is almost the same. Originally, the power of this speaker is 40W. If the general family uses a space of 100 square meters, it is more than enough. , If you put it on a square, or use it in a large classroom, its power is bound to be unbearable.
Note three when using the speaker:
Prevent the sudden impact of large signals: Generally, there are the following situations: First, because the potentiometer switch has not been turned to the lowest level after the last listening, or someone has moved the potentiometer by mistake, it will be in a high volume state when the sound is turned on, resulting in a large signal Shock. 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 five when using the speaker:
Avoid use in harsh environments: the various parts of the speaker such as wood veneer, paper cone, tweeter film, suspension, centering bracket, adhesive, voice coil, etc. are mostly 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 above 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 .
