Xiao Bian introduces some basic common sense of sound maintenance of different materials in daily life:
1. There may be many friends who are unclear. In fact, the various components of the speaker are sensitive to changes in temperature and humidity, such as the outermost wood grain veneer, paper cone, treble silk film, hanging edge, and centering. Brackets, adhesives, voice coils, etc. If the temperature of the working environment is too low or too high, it will affect the stability of these parts.
The normal working temperature of the equipment should be 18 ° C ~ 45 ° C
The effect of humidity is also very large. For example, the wood grain skin outside the dry speaker may be prone to peeling. The humidifier can be used to increase the air humidity. Humidity is too high, the cone's cone is prone to moisture and mildew, resulting in weak sound playback, and the exposed metal wires are also susceptible to oxidation. In the wet areas of the south, the horn is prone to mildew, so it is generally not recommended to install it in the basement. In this regard, the solution is to install a dehumidifier indoors or to place a desiccant.
2. Avoid direct sunlight in audio equipment, and avoid near heat sources such as heaters.
3. After the audio equipment is used up, each function key should be reset. If the function key is not reset for a long time, the pulling button spring is under stress for a long period of time, and it is easy to cause malfunction.
4. Before switching the audio power supply, turn the power of the amplifier to the minimum, which is the most effective protection for the amplifier and speakers.
5. From the front to the back when starting up, first open the CD player, then open the front and rear levels, turn the volume of the power amplifier to the minimum when starting up. Turn off the power amplifier first, and let the amplifier's amplification function be completely turned off. At this time, when you turn off the front-end equipment, no matter the large impact current, it will not affect the amplifier and the speaker.
6. The machine should be used frequently. If it does not rotate for a long time, some parts will be deformed.
7. Power on regularly. In the long-term non-use, especially in the humid, hot season, it is best to power on for half an hour every day. In this way, the heat generated by the internal components can be used to remove the moisture, and the internal coil, the speaker voice coil, the transformer and the like are protected from moisture and mold.
8. Wipe the surface of the machine with a clean, damp soft cotton cloth at regular intervals; when not in use, cover the machine with a dust cover or cloth to prevent dust from entering.
9. Do not open the amplifier cable to connect the speaker cable, because the speaker's terminal is generally close to the distance, the speaker cable is two tightly parallel, the wiring will often accidentally short the speaker cable, the consequences will be rapid Burned the amplifier.
10. Only put some soft music and listen to music at medium volume within half an hour after starting up. After the warm-up of the standby device, turn on the volume and enjoy it.
Babbitt Wire is with tin as the base, the product is added with certain amount of antimony, copper
or other improved elements.
Sn Sb7Cu3 Babbit metal is suitable for metal spraying on the end face of metalized ï¬lm capacitor. With strong adhesive force, good weldability and low loss angle, it is an ideal metal spraying material for laminated capacitor.
Other trade marks are suitable to use CMT, TIG and MIG technology to manufacture sliding bearing bush material layer. It is of high bonding strength with substrate, with material utilization rate of 70~80%. It has small amount of ingredient segregation without any loose or slag inclusion. The internal control standard of the alloy composition is prevailing over GB/T8740-2013. Babbi1 metal added with improved elements can substantially enhance the service life.
