Speaker Magnets, Maglev Trains Magnets Manufacturer – China Rare Earth Magnet Limited
Speaker Magnets , Guard of Stereo
Most commonly applied to stereos, permanent magnets directly bring impact on effect of speakers of stereo.
Firstly, with bad performance of speakers, magnetism of magnetic steels decline. As we all know, speaker sensitivity depends on magnetism of permanent magnets, quality of cone and quality of assembly techniques. We can use magnetic objects to touch magnetic steel and judge the strength of magnetic steel according to the attraction. If the magnetism is weak, we have to replace the speakers.
Secondly, there is something wrong with frequency dividers. Unqualified components in frequency dividers hinder the signal of the related frequency band, which results in failure of speakers. Therefore, we need to check carefully that whether there are short circuits in divided capacitance connecting with low pitch speakers and in divided inductance coil lick with high pitch coil.
Thirdly, core of magnetic conductor in speaker become loose, which will be attracted by laminate for magnetic conductor. Therefore, if we cannot press the cone, it possibly means that sound coil is pinned by the core. So we should disassemble the core of magnetic conductor and fix it again.
The Modern Application of Permanent Magnets
Several years ago, maglev trains were formally opened in Shanghai, China, which was a big surprise to some foreigners. The appearance of maglev trains is indispensable from the achievement of people’s research on magnets.
Frankly, maglev trains are a kind of trains supported by electricity without non-contact rails. They are amazingly suspending, which can be understood by most people. Maglev trains are the fasted ground vehicles in the world, with speed, safety and comfortableness.
Magnetic modern applications are not only include maglev, but electric magnets and permanent magnets. It can be physically explained that a solenoid can produce magnetic field when it power on. The biggest characteristic of permanent magnets is that magnetism on two ends is the strongest and it can be changed freely. Meanwhile, direction of the magnetism can move according to our different ideas.
Besides, there are more and more products that made by magnets, of which the basic theory cannot be separated by magnets. Due to enlightenment of magnetic theory, we can promote the application of magnets and the achievements.
