How to care for the speaker
How can we protect the speakers? How to make it have the longest service life? How to maintain good sound quality for a long time? Here are some tips for speaker maintenance.
Where the speakers are placed
The placement of the speaker should not be considered as a simple problem. The precise parts inside the speaker, if placed in a place exposed to sunlight for a long period of time, or placed in hot places such as hot air, will cause blistering on the surface of the cabinet or aging of electrical components. Do not place the speaker in a humid place to avoid rust or mold on the voice coil. At the same time, in order to prevent the speaker from making noise during operation, it should avoid being too close to mobile phones or electronic devices with strong magnetic properties.
The environment in which the speakers are placed
The various components of the horn are mostly sensitive to changes in temperature and humidity. If the ambient temperature is too low or too high, it will affect the stability of these parts. If the temperature is lower than 5 ℃, the hanging edge is easy to become brittle and crack. Therefore, when working at a low temperature, you must "warm up" the speaker, play some soft music in advance, and lower the level. After about 20 minutes, you can listen to music without worry. If the temperature is higher than 35 ℃ , Overheating of the voice coil will cause sound degradation. It is recommended to avoid using the horn in high-temperature environments or use it under the condition of the temperature control of the air conditioner. Humidity also has a great impact on the operation of the horn. Too dry environment will make the horn box body The exterior veneer cracked or cracked, the solution is to put a humidifier or a basin of water in the room; if the humidity is too high, it is easy to make the sound basin wet and moldy, resulting in weak sound playback, it is recommended to use dehumidification indoors The temperature of the horn is adjusted. In addition, the dust removal of the horn is very important. When the horn is idle, a dust cover should be added to prevent dust from touching the horn unit and reducing unnecessary damage. The surface of the horn box can be cleaned Wring the towel with wet water and wipe after wiping it, but the speaker unit must not get wet. After wiping, be sure to wait for the moisture to dry before turning on the phone, otherwise it may cause short circuit Thermal phenomena.
Things to pay attention to when using
When using an active speaker, due to its built-in power amplifier and electronic parts to avoid the impact of large currents, it is best to turn the volume of the speaker to the lowest position when switching the power of the speaker, and then adjust the normal listening volume after turning on the power. When not in use for a long time, turn off the power of the speaker and pull out the power plug. After playing for a long time with high sound pressure, the heat sink behind the speaker will become very hot. Pay special attention to whether there is enough air circulation behind the speaker to guide away the heat. In addition to this, the volume of the speaker should not be adjusted too high, about 1/2 is the most suitable, because there is a danger of burning the speaker unit at the maximum volume. For example, when singing karaoke, pick up the "microphone" as far as possible from the speaker, and don't point the direction of the "microphone" toward the speaker to avoid howling and burning the tweeter.
