As someone who loves music, we always have a speaker at home to some extent. However, sometimes we may find that the sound system suddenly presents various problems, most of which are formed when we use the speaker. So, what issues should we pay attention to when using the speaker? Today, the editor will give us a brief introduction.

Note 1 when using a sound system: Regarding newly purchased speakers, we need to run them in like a new car, which is known as "burn-in" in the speaker industry. Only after sufficient running in can the speaker fully unleash its potential. Due to the fact that the speaker, an important component inside the speaker, is a key component that determines the sound quality and service life of the speaker, and most speakers are composed of reinforced paper pots or bulletproof cloth, new speakers are generally stiff and require a softening process. Therefore, the speaker needs to be cooked for better sound and durability. Many people have found that speakers need to be cooked for a while to sound better. We agree, but the difference is that some people promote using high volume to make a big fuss. This is not right. In fact, the running in of a speaker and a sedan is the same principle. Slowly running in will allow the mechanical part (the vibration part is equivalent to the mechanical part) to break in. Crazy burning does not benefit the speaker at all, and if not cooked well, the voice coil may deform. Therefore, slow simmering over low heat is the only way to have a taste, otherwise it will simply present problems such as sharp, hoarse, cracked, and uneven sounds. As for the specific method of boiling the machine, please search for relevant knowledge online, and it will not be elaborated here.

Note 2 when using a sound system: Issues in the application location: Any sound system that is turned on will exhibit sound breaking and other phenomena, so turning the volume to 8 is almost the result. Originally, this sound system had a power of 40W, but if used in a typical household space of 100 square meters, it would be more than enough. If you place it in a square or a large classroom for use, it will inevitably be unable to withstand its power.

Attention during the use of sound system three: To prevent sudden impact of large signals: There are generally several situations: first, due to the potentiometer switch not turning back after the previous listening or someone accidentally moving the potentiometer, it will be in a high volume state as soon as the sound is turned on, forming a large signal impact. Secondly, there are sudden and dynamic segments in the music. These fragments are intended to emphasize contrast, as the signal is mostly weak before the arrival of major dynamics. At this moment, if you are not mentally prepared and turn up the volume, a large dynamic signal can easily damage the speaker. Such as the sound of explosions, drums, thunder, and so on. The third situation is when the audio system is working normally, suddenly unplugging and plugging in the signal or power lines can cause a large current surge, which is the simplest way to damage the speaker.

Attention when using the sound system: 4. Pay attention to standard operation: When listening to the sound, first check whether the wiring is correct and whether the position of the potentiometer is too large. When starting, shutting down, restarting, and other operations, the speaker volume should be turned off or the power should be turned off to prevent large surge currents from damaging the speaker. When singing karaoke, try to stay away from the speaker and avoid pointing the microphone towards the speaker to prevent whistling or even burning out the treble unit. In order to protect the speaker, in general use, the volume of the speaker should not be turned on too high. As long as it is sufficient, about 1/2 is sufficient. Due to the issue of sound distortion, some large dynamic discs are definitely the killer of the speaker. The active speakers on the market, although their nominal power is very high (some even exaggerate to a few hundred watts), that is not the actual power, usually a few tens of watts is considered large. So when using it, do not work at high volume for a long time, otherwise it will easily damage the power supply and amplifier circuit. The bookshelf style speaker should prevent accidental collision and fall from the tripod, and apply a few pieces of double-sided tape to the bottom of the box. When the speaker is used for a period of time, the wiring terminals of the speaker cable will be more or less oxidized. This oxide film will greatly affect the touch state, and then cause a decrease in sound quality. Users can use cleaning agents to clean the touch points in order to maintain a consistent connection state.

Note 5 when using a speaker: Prevent use in harsh environments: Various components of the speaker, such as wood veneer, paper speakers, tweeter film, hanging edges, centering brackets, adhesives, voice coils, etc., are mostly sensitive to changes in temperature and humidity. Both too low and too high temperatures can affect the stability of these components. For example, if the temperature is too low and less than 5 degrees Celsius, the hanging edge will become brittle. If the volume is turned up at this moment, it is easy to form hanging edge cracks. If the temperature is too high and exceeds 40 degrees Celsius, the voice coil will overheat and cause sound degradation. So the speaker should be kept away from areas exposed to sunlight, around radiators, and in areas with sub zero temperatures. The influence of humidity is also significant. If it is too dry, the wooden veneer outside the speaker will burst, and the thick wooden box body will also have simple cracks. The solution is to install a humidifier or place a basin of clean water indoors. If the humidity is too high, the sound pot will become damp and moldy, resulting in weak sound and simple oxidation of the wiring. The solution is to place some dehumidifiers and desiccants indoors. In addition, dust prevention and cleaning of the speaker are also important. When not listening to the speaker, add a dust cover. The exterior of the speaker can be cleaned by using a towel dipped in warm water, wring it dry, and then wiping it. However, it is necessary to remember to wait for all the water to dry before turning on the speaker.

Attention when using a sound system: Sixth, the placement of the speaker should be carefully considered. Firstly, the speaker should be placed in a position that prevents direct sunlight, and it is not advisable to place the speaker around the radiator or in areas with low temperatures. Otherwise, it may cause bubbles on the surface of the speaker or aging of electrical components. It is also important not to place the speaker in a damp area for a long time to avoid rusting or mold on the sound coil. Additionally, do not place the speaker too close to the CRT display. Due to the delicate nature of CRT monitors, even anti magnetic speakers can have a certain impact on the display. Similarly, the speaker should also be kept away from strong magnetic fields. If the phone is close to the speaker, it will make noise when there is an incoming call. Secondly, in order to save space, we often place the speakers under the computer desk or stack them together, which is extremely unscientific. Even with a sound card and advanced speakers, there will not be good sound performance in this situation, let alone on-site sound positioning. The correct method should be to place it symmetrically around the monitor (using a regular 2.1 speaker as an example). And ensure that the speaker is facing the user, the subwoofer can be more sensitive in orientation due to its weak directionality. For speakers with high volume, use a floor stand and do not place the speaker directly on the computer desk (especially the subwoofer) to avoid resonance and distortion with the computer desk.
