Neodymium Speaker Magnets

Speakers operate by using a magnetic field to generate motion in a coil and speaker cone to project an amplified sound signal. In neodymium speakers, the rare-earth element is used as the primary material in the magnets that create the field needed to drive the speakermovement.

Neodymium magnets made high-fidelity ear buds possible, as they can pack a strong magnetic field into a tiny package.
