How to maintain the loudspeaker.Bar lighting speaker

　　The speaker system should present good results, and the requirements for speakers are very high. Today, let's talk about some skills of speaker maintenance.

　　First of all, the placement position of the speaker: There are various precision parts in the speaker, which should not be exposed to the sun for a long time, or placed in a hot place such as near a hot gas, or placed in a humid or humid, dry and repeated environment, which may easily cause the aging of the rubber edge of the speaker and the sound basin. At the same time, avoid getting too close to the mobile phone or electronic equipment with strong magnetism, otherwise the horn will make noise during operation, or condition the magnetic shield.

　　Secondly, precautions during loudspeaker playing:

　　1. Don't turn the volume of the speaker too high, for one thing, it is easy to hurt your ears. Second, when playing at a high volume, the radiator behind the speaker will become very hot, which is easy to burn the speaker unit. It is most appropriate to turn the volume to about 1/2.

　　2. Various parts of the horn are sensitive to changes in temperature and humidity. When the temperature is lower than 5 ℃, the hanging edge is easy to become brittle and cracked. Before use, it is better to play some soft music for about 20 minutes, and turn down the volume. After warming up, play it freely; When the temperature is higher than 35 ℃, overheating of the voice coil will cause sound deterioration. Try to avoid using the horn in a high temperature environment, or in a temperature controlled condition such as an air conditioner. If it is too dry, the exterior veneer of the horn box will burst or crack. You can put a humidifier or a basin of water beside it; If the humidity is too high, the sound basin will become damp and moldy, which will lead to weak sound playing. It is better to dehumidify the room.

　　3. The components in the loudspeaker shall avoid the impact of large current, so it is better to adjust the volume to the lowest position before switching on the loudspeaker power supply, and then adjust the volume to the normal listening volume after turning on the loudspeaker.

　　4. The dust removal of the horn is also very important. Add a dust cover when the horn is not in use, and prevent children from touching the horn unit to reduce unnecessary damage. When cleaning the surface of the horn box at ordinary times, do not wet the horn unit, and wait until the box is completely dry before starting to use, otherwise it is easy to cause short circuit and heat.

　　5. When it is not used for a long time, it is better to turn off the horn power and pull out the power plug.

　　Especially for high-end speakers, the maintenance is very necessary. Because after the horn broke, the sound was also damaged after maintenance.
