NdFeB magnets and still have to use our lives to these effects is great for our industry has brought many opportunities for development. Anti-fouling in industry, high-strength after water through NdFeB magnetization process, water molecules bond simultaneous deformation angle and length of the hydrogen bond angle is reduced from 105 degrees to about 103 degrees, so that the water changes the physical and chemical nature of series sided magnet, water activity and the solubility is greatly improved. In the illnesses and health care industry, a lot of practice and scientific tests proved high-strength magnetic NdFeB alter the surface tension of water, density, solubility and other physical properties, have a significant impact on the pH and other chemical properties of magnetized water can increase water activity and biofilm permeability. Effect of the permanent magnet magnetic sound is relatively large, it is possible to affect the effectiveness of their sound. Poor magnet performance of a speaker magnetic magnet decreases. We know that the speakers are mainly dependent on the sensitivity of the permanent magnet magnetic sound within the cone of quality and assembly process of the pros and cons. We can take advantage of ferromagnetic objects to touch the magnet, and then appealing to a rough estimate of the size of the magnetic strength of the magnet, if the magnetic weak, only replace the speaker. Divider exception. If the sound of the divider adverse elements, the corresponding signal band also will be blocked sided magnet, and the band appeared speaker volume glitches. Then we need to check and subwoofer crossover parallel focus whether it is short-circuited capacitor, inductor and crossover and tweeters in parallel whether a short circuit between the layers appear. Guided core leg loose. When a core pillar when the speaker's guide loose, then it will be sucked into the permeable plate to one side, so that the voice coil by squeezing therefore will impede the normal sound. Therefore, we recommend you can use a variety of hand-tapping cone magnet in the maintenance, if by not moving, then the most likely to be a core pillar of the voice coil is suppressed, at the same time need to be removed before we can re-cement reinstated.
