to produce the sound by interacting with the changing magnetic
field, driving the cone. Speaker manufacturers have been searching

of tone quality in different ranges, such as AlNiCo, Ferrite,
Neodymium, SmCo etc. China Magnets Source Material Limited can
provide speaker magnet based on your design.
