Neodymium Magnets in speakers:
A component that perhaps doesn’t get the exposure that it should – the magnet. While each speaker driver is made up of two magnets – an electromagnet and a natural/permanent magnet. Why are neodymium magnets so special? It all has to do with size and strength.Neodymium magnets are the strongest type of natural magnet in the world, and can pack an extraordinary amount of magnetic energy into a very small package.This means that even in small amounts, these magnets are still extremely strong.It is for this reason that a number of Fluance speakers use neodymium magnets in their tweeters. The strength of these magnets allows for an extremely powerful driver, without making any sacrifices in overall weight or depth.As a result, Fluance neodymium tweeters are light, powerful, and have a smaller profile than other drivers that use lower quality magnets. In addition, the strength of the neodymium magnets allow the tweeters to perform better in more demanding situations, resulting in less distortion at any operating level. Pros and cons of using neodymium: Improve the sensitivity of loudspeakers but also greatly reduce the number of magnets used. NdFeB has the advantages of high-cost performance and good mechanical properties, while its disadvantages are low Curie temperature, poor temperature characteristics and easy to be powdered and corroded. It offers lower corrosion resistance. It is brittle and hence gets break/crack due to collisions. |
