Product Description
Sintered neodymium magnet are widely used in speaker, it provides a permanent magnetic
field for the speaker coil, which is embedded in the paper of the speaker cone. 
When theaudio signal flows throw the speaker coil, it generates a small magnetic field. This small
magnetic field is repelled to the permanent magnetic field. Thus the paper cone moves
away from or closer towards the back of the speaker. Hence as the strength of the audio
signal wiggles the paper cone wiggles back and forth, and you get sound waves that
match the audio signal. 
Ordinary ferrite magnet is mainly used for low-end headphones. Neodymium magnets
for high-end headphones, so it has better sound quality, good elasticity, good voice
performance, and accurate positioning of sound field. 
We can produce the NdFeB ring magnets in different sizes, different grades (strengths and temperature ratings), different coatings and in axial or diametric magnetization. 
There exits two styles "pure" rings and "countersunk" rings. The holes are centrally located. The countersunk ring allows for the magnet to be screwed onto another item.
Due to their shape, the ring magnets have a higher permeance coefficient than the same size disc magnet. 
This means they can resist demagnetization better, making them ideal for repulsive applications.
