It is well known that the good or bad of speakers can affect the style of the entire sound system. Good speakers have their own personality. The sound quality of the speakers in the sound system is restored as a restore device, and the sound quality is directly expressed by the speakers. In other words, the speaker plays a decisive role in the overall sound system, while the magnet plays a decisive role in the speakers. The rare earth neodymium permanent magnet is a very good material for making the speaker.

Initially due to cost problems, neodymium magnets were only used in medical MRI, aerospace and other fields. It wasn't until 2006 that JBL, the world's audio giant, began using neodymium magnets as a magnetic material for speakers in the field of high-end audio, and its advantages were immediately demonstrated: small, light weight, high sensitivity, low distortion, and a small-power amplifier. Now the field of professional audio is moving in this direction, and become the main selling point of manufacturers.

How the speaker works: the permanent magnet generates a magnetic field in the ring air gap of the magnetic circuit through the moth, and the sound ring connected to the speaker's paper basin is inserted into the ring air gap.
