About The Working Principle Of NdFeB Magnets Used in Speaker Magnets

About the working principle of NdFeB magnets used in speaker magnets? The magnet in the speaker device is the speaker magnet, referred to as the speaker magnet or the speaker magnet. Working principle: when the changing current passes through the sound, the magnet becomes an electromagnet. The direction of the current changes constantly, and the energized wire of the electromagnet is forced to move back and forth continuously in the magnetic field, which drives the paper cone to vibrate back and forth. The sound will make a sound.

Types of motor magnets: There are two types of magnets commonly used in motor products: ferrite magnets and NdFeB magnets. NdFeB magnets can be made into circular multi-stage magnetization according to product design, circular ring radiation magnetization, and circular ring radial magnetization. Magnetized, tile-shaped, fan-shaped, square, twisted tile and other shapes.

NdFeB has high suction power with homosexual ferrites, and small suction power with heterosexual ferrites, which is also well understood. For anisotropic ferrites, NdFeB only reverses the magnetization of the ferrite on the surface layer, and the slightly deeper place is still repelling. And isotropic ferrite still has a lot of magnetic moments that have not been magnetized, and NdFeB will be magnetized obediently.

The first reaction of many customers is that NdFeB speakers are too expensive! But there are certain reasons for the high price, because NdFeB magnet speakers are smaller in size, stronger in magnetism, and better in sound quality and tone!
