If you are a music enthusiast who often wears headphones to listen to music, then you may be interested in our article today. In this article, we will try to find out the advantages of neodymium magnets in headphones and what makes them superior over other magnets. Before diving into the advantages of neodymium magnets in headphones, let’s figure out what are neodymium magnets.
Neodymium magnet, also known as NdFeB magnet, is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B).
Neodymium magnets were first discovered in 1982 by Masato Sagawa of Sumitomo Special Metals in Japan. The BHmax of this magnet was greater than the BHmax of a samarium cobalt magnet. Later, Sumitomo Special Metals successfully developed the powder metallurgy process and General Motors successfully developed the melt-spinning process, both of which were capable of preparing NdFeB magnets.
Thanks to their excellent magnetic properties, NdFeB magnets are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace, and other fields. More common applications of NdFeB magnets are in the permanent magnet motors, speakers, magnetic separators, computers Disk drives, magnetic resonance imaging equipment instruments, etc.
Then what are the advantages of neodymium magnets in headphones? What makes them unique?
First of all, compared to other types of magnets, neodymium magnets are usually lighter in weight and smaller in size, which makes them ideal for headphones. After all, whether you wear your headphones or carry them with you, you don’t want them too heavy.
In addition, compared with other kinds of magnets such as ferrite magnets, SmCo magnets, and AlNiCo magnets, neodymium magnets have more magnetic energy per ounce. In fact, the sound clarity and basic performance of the headphones with neodymium magnets are eight times that of the headphones with ferrite magnets.
Besides, compared with other types of magnets, neodymium magnets are capable of producing higher sensitivity and greater sound output but use less power to do so. By using high magnetic flux, they can help produce music at quite a high sound pressure level. Therefore, neodymium magnets allow you to enjoy a better headphone with excellent sound quality without significantly increasing the price.
Thank you for reading our article and we hope it can help you to have a better understanding of the advantages of neodymium magnets in headphones. If you want to know more about neodymium magnets, we would like to advise you to visit Stanford Magnets for more information.
