How to use and maintain the loudspeaker correctly

1.Precautions for the first use of newly purchased speakers: The cooker is like the running in period of new items. Only after full running in can the speakers give full play to their potential. As the "speaker" is the key component to determine the sound quality and service life of the speaker, and most speakers are made of reinforced paper pots or bulletproof cloth, new pc speakers are generally rigid and need to be softened, so the speaker needs to be heated for a while to sound better and be more durable. Many people find that speakers need to be cooked for some time to sound better. We agree. The only difference is that some people advocate using loud music. This is wrong. In fact, the running in of the sound box and the car is the same. Slowly running in will make the mechanical part get the best running in. Crazy cooking is not good for the speaker at all. The voice coil that cannot be well cooked may be deformed. Therefore, slow simmering has a taste. Otherwise, it is easy to have sharp, hoarse, broken, uneven and other problems.

2.To prevent sudden impact of large signal: -- There are generally the following situations: - It is because the potentiometer switch has not been turned to the lowest position after the last hearing or someone has moved the potentiometer by mistake, and it is in a loud volume state as soon as it is turned on, causing large signal impact. Second, there are sudden big dynamic fragments in the music. In order to emphasize contrast, most of these fragments have weak signals before the arrival of the big event. At this time, if you are not prepared, turn up the volume and the dynamic signal to easily damage the horn. Such as explosion, loud drum, thunder, etc. The third situation is that when the audio system is working normally, the signal line and power line are suddenly plugged in. At this time, a large current impact will occur and the speaker is most likely to be damaged.

3.Avoid using in harsh environments: various parts of the speaker, such as wood veneer, paper voice cone, tweeter film, hanging edge, centering bracket, adhesive, voice coil, etc., are sensitive to changes in temperature and humidity. If the temperature is too low or too high, the stability of these parts will be affected. For example, if the temperature is too low and less than 5 ℃, the overhang is easy to become brittle. At this time, if the volume is turned up, it is easy to cause the overhang to break. If the temperature is higher than 40 ℃, the voice coil will overheat, which will cause sound deterioration. Therefore, speakers should not be placed in places exposed to sunlight, near radiators and at places with sub zero temperatures.

4.Pay attention to standard operation at ordinary times: check whether the wiring is correct and whether the potentiometer position is too large before listening. During startup, shutdown, restart and other operations, the speaker volume should be turned off to the minimum or the power should be turned off to prevent damage to the speaker caused by large impact current. When singing karaoke, try to stay away from the speaker, and do not point the microphone at the speaker to avoid howling or even burning the tweeter. At the same time, in order to protect the speaker, in general applications, the volume of the speaker should not be too high, as long as it is enough, about 1/2 can be used. Therefore, when using, do not work at a high volume for a long time, otherwise the power supply and amplification circuit will be easily damaged. The bookshelf type speaker should prevent accidental collision and fall from the foot stand, and it is better to stick a few pieces of double-sided adhesive tape on the bottom of the box. When the speaker is used -- after a period of time, the terminal of the speaker line will be more or less oxidized, and this oxide film will greatly affect the contact state, thus reducing the sound quality. Users should clean the contact points with detergent to maintain the best connection state.

The above is about how to use and maintain the loudspeaker correctly.
