Magnet manufacturers about how long to keep the magnet magnetic magnets when we see will feel these are very familiar with the use of the fan-shaped magnets price, which can provide more convenience for our heart-shaped magnet, which is mainly to use in the industry. So when it comes to the magnet may be a lot of people do not know why the magnetism of these magnets will become weak, in fact, these are the reasons for the magnet, we now take a look at the magnet manufacturers to tell us about how long to keep magnetism. The impact on the sound of the magnet permanent magnet is relatively large oval magnet manufacturer, which may affect the effectiveness of their sound. Poor 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, 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 suggest using a hand tap cone 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.
