Product Description
Speakers are one of the raw materials of electro-acoustic equipment. The most basic material for manufacturing speakers is rare earth NdFeB permanent magnet materials. Speaker magnets are generally called speaker magnets. The use of rare earth NdFeB magnets can not only improve the sensitivity of the speaker, but also greatly reduce the number of common magnetic fields.

Block Neodymium Magnet Advantages
1.Material
The multi-purpose rare earth blocks are the number one magnet of choice due to the power of today’s magnetic alloys. Our neodymium block magnets, also called rare earth block magnets, are offered in several sizes, shapes, and grades. They are the best alternative if you require a multipurpose magnet with maximum magnetic strength.
2.World's most precise tolerance
The tolerances of magnets can be controlled within ±0.05mm or even more.
3.Coating / Plating
Options: Zinc (Zn) , Nickel (Ni-Cu-Ni), Black Epoxy, Rubber, Gold, Silver, etc.
Zinc coating is a standalone plating with only one layer. It is a self- sacrificing coating, meaning when the material corrodes the outside turns white creating a durable layer of protection.
4.Magnetic Direction: Axial
The regular magnetic direction of block magnet are magnetized through the length, width, or thickness.
