traditional applications of permanent magnets
Speakers and headphones are traditional applications of permanent magnets. After the rise of rare earth permanent magnet material, NdFeB permanent magnets can reduce the size and improve performance at the same power output and sound quality. Currently, rare earth permanent magnet speakers and headphones have been applied to other areas of advanced Walkman. With technological innovation and development of audio equipment to small high-fidelity and downsizing, it requires the use of higher-performance magnet, in this area, NdFeB magnet has begun to be widely used.
