How to properly protect your beloved speakers? How to make speakers have the longest service life? How to make speakers maintain good sound quality for a long time? Let us discuss the "speaker maintenance experience" with the speaker expert.
Do not ignore this seemingly simple problem. Many parts of the speaker are very precise parts. If they are exposed to direct sunlight for a long time or placed in overheated places such as heating, they will cause blistering on the surface of the cabinet. Or electrical components are aging. Don't place the speaker in a damp place for a long time to avoid rust or mold on the voice coil. At the same time, in order to make a dissonant noise when the speaker is not working, avoid getting too close to magnetic electronic devices such as mobile phones.
The various parts of the speaker are mostly sensitive to changes in temperature and humidity. If the temperature is too low or too high, it will affect the stability of these parts. If the temperature is less than 5°C, the overhang will easily become brittle and crack. Therefore, to work in low temperature conditions, you must "warm up" the speakers, play some soft music in advance and turn down the level. After about 20 minutes, you can sit back and relax and use your speakers at ease. If the temperature is higher than 35°C, overheating of the voice coil will cause sound deterioration. It is recommended to avoid the use of speakers at high temperatures or use it under air-conditioning temperature control conditions.
Humidity also has a great influence on the work of speakers. Excessive dry conditions will cause the veneer outside the speaker to burst or cracks. The solution is to buy a humidifier or put a basin of clean water indoors; and if the humidity is too high, it will easily make the sound cone damp and moldy, causing weak sound playback. It is recommended to be indoors Place the desiccant before use. In addition, it is very important to remove dust from the speaker. When the speaker is not in use, a dust cover must be added to prevent dust from touching the playback unit and reduce unnecessary loss. The surface of the speaker can be cleaned with a towel dampened with water and wrung out and wiped, but do not get the speaker unit wet. After wiping, you must wait until the moisture is completely dry before turning it on, otherwise it will easily cause short-circuit heating.
Use and maintenance
Active speakers have a built-in power amplifier and the chip must avoid the direct impact of large currents. Therefore, it is better to turn on the volume to a low level when switching on and off the speakers and then turn it on again, and then adjust the volume normally after turning on the speaker. When not in use for a long time, turn off the switch and pull out the power plug. After playing loudly for a long time, the rear panel of the speaker will become very hot, so pay special attention to this. In addition, the volume of the speaker should not be turned on too much, about 1/2 is the most appropriate, because the sound unit will be burned out when the volume is louder. When 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.
