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 
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 audiosignal 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 lowend headphones. Neodymium magnets for highend headphones, so it has better sound quality, good elasticity, good voice
performance, and accurate positioning of sound field.
