Let’s introduce how to correctly use and maintain the speakers
The certification of audio products can ensure the quality and safety of the speakers to a certain extent. , some readers also asked, what safety issues should we pay attention to when using speakers? Under what conditions should speakers be used? Generally speaking, the ambient temperature should be controlled at least between ℃ and ℃, and the temperature environment should avoid large temperatures as much as possible. fluctuations. Excessive temperature changes and the use of speakers in extremely low and extremely high environments will cause irreversible damage to the sound system. In terms of humidity, the speaker should be placed at a relative humidity between % and %. An environment that is too humid will cause premature failure of components inside the machine, or rust inside and outside the machine.
When maintaining the box, avoid direct sunlight. It is not advisable to place the speaker next to a radiator or in a place where the temperature is too low to avoid blistering on the surface of the box and aging of electrical components. Do not get close to easily magnetized items such as monitors. Even if they are anti-magnetic, they will have a certain impact on the monitor. Similarly, the speaker should be kept away from strong magnetic fields. If the mobile phone is close to the speaker, the speaker will make noise when answering the phone. To clean the surface of the speaker, use a towel dipped in warm water and wring it out, then wipe it. Wait until the water is completely dry before turning it on.
Electrical Maintenance of the Speaker
Since the speaker has a built-in power amplifier, the amplifier chip is afraid of direct impact of large (instantaneous) current. Therefore, when opening the speaker, it is best to turn the volume down to a low level and then turn it on again. After turning it on, you can increase the volume normally. . When shutting down, also turn down the volume first and then turn off the power. After playing at high volume for a long time, the rear panel of the speaker will become very hot. It is best to shut down the speaker at this time to avoid accidents. Qualified power sockets should be used. When not in use for a long time, the switch should be turned off and the power plug should be removed.
Don’t turn up the volume of the speakers too high, at least/around, because some songs have extraordinary treble or dynamic amplification, which will burn the speakers when the volume is turned up to full. When the power is connected, short-circuiting the speaker cable will cause a short circuit and burn the speaker, so be careful when handling the wires. It is best to dip the wire ends in solder to prevent burrs and maintain the appropriate length.
Troubleshooting
When there is no sound from the speaker or only one speaker makes sound, you should first check whether the power supply and connecting wires are connected properly. Sometimes too much dust often leads to poor contact. If you are not sure whether it is a problem with the sound card, you can replace the sound card (for example, connect a Walkman) to determine whether it is a problem with the speaker itself. When you hear the sound coming from the speakers is relatively hollow and the sound field is scattered, be careful not to connect the left and right channels of the speakers in reverse. Consider transposing the two sets of audio cables. When the sound is obviously distorted, you can check whether the adjustment of the bass, etc. is too large. When there is noise from the speaker, you can consider changing the sound source or whether there is a strong magnetic field nearby.
