How should we protect the horn? How to make it have the longest service life? How to maintain good sound quality for a long time? Here are some tips for horn maintenance.

Location of speakers

The placement of the horn should not be considered as a simple problem. The horn contains precise parts. If it is placed in a position exposed to sunlight for a long time or in a place with high heat such as hot air, it will cause blistering on the surface of the box or aging of the electrical components. Moreover, the horn should not be placed in a humid place to avoid rusting or mildewing of the voice coil. At the same time, in order to prevent the horn from making noise during operation, it should avoid getting too close to the mobile phone or the electronic equipment with stronger magnetism.


The environment in which the horn is placed.

Most of the various parts of the horn are sensitive to changes in temperature and humidity. If the ambient temperature is too low or too high, the stability of these parts will be affected. For example, if the temperature is lower than 5℃, the hanging edge will easily become brittle and crack. Therefore, in order to work at a lower temperature, one must "warm up" the horn, play some soft music in advance and turn down the level. after about 20 minutes, one can rest easy and listen to the music heartily. If the temperature is higher than 35℃, voice coil overheating will cause sound deterioration. It is recommended to avoid using horn in high temperature environment or under the condition of air conditioner temperature control. Humidity also has a great influence on horn operation. If the environment is too dry, the veneer of the horn box will burst or crack. The solution is to put a humidifier or a basin of clean water indoors. However, if the humidity is too high, it is easy to make the sound basin damp and moldy, resulting in weak sound playing. It is recommended to use dehumidifier to adjust the temperature indoors. In addition, the dust removal of the horn is very important. When the horn is idle, a dust cover should be added to prevent children from touching the horn unit and reduce unnecessary damage. The surface of the horn box can be cleaned by wringing it dry with a towel, but never wet the horn unit. After wiping, it must wait until the water is completely dry before starting the machine, otherwise it is easy to cause short circuit and fever.


Matters needing attention when using

When using an active horn, electronic parts should avoid the impact of large current due to its built-in power amplifier. Therefore, when switching on and off the power supply of the horn, it is best to adjust the volume to the lowest position, and then adjust the volume for normal listening after starting up. When not in use for a long time, turn off the horn power supply and unplug the power plug. After playing for a long time and with high sound pressure, the heat dissipation plate behind the horn will become very hot. Special attention should be paid to whether there is sufficient air circulation behind the horn to conduct heat away. In addition, the volume of the loudspeaker should not be turned too high, about 1/2 is the most suitable, because there is a danger of burning the loudspeaker unit when the volume is at its maximum. For example, when singing karaoke, the microphone should be as far away from the speaker as possible, and the microphone should not be pointed to the speaker to avoid burning the tweeter due to howling.
