Super strong neodymium ring magnets for motor
General Information
Sintered neodymium iron boron rare earth magnet are widely used in speakers, the rare earth permanent magnets can provide the permanent magnetic field for the speaker coil, which is embedded in the paper of the speaker cone. When the audio signal flows throw the speaker coil, it generates a small magnetic field the strength of which varies with the strength of the audio signal. This small magnetic field is repelled by or attracted to the permanent magnetic field produced by the speaker magnet. 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. Only the field in front of the speaker magnet (where the speaker cone is located) is of any use. The field that comes out the back of the magnet serves no purpose, and you might as well use it to stick the speaker to the fridge. Usually neodymium magnet are used as speaker magnet.
