Generally, NdFeB audio speakers mainly include car audio and high-end speaker audio. Their advantages are small volume, large power and wide frequency range under the same magnetic flux. At present, hifi earphones basically use this kind of magnet. Its disadvantage is that it contains rare earth elements, so the material price is high.
