What Are Neodymium Speakers?
Neodymium is an element with specific characteristics that make it particularly well suited for use in speaker construction. 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 speaker movement.
Neodymium shows up in a wide variety of speaker types produced by a large range of manufacturers; however, there are some specific applications that it is best suited for. The light weight of the material makes it useful when designing both very large and very small systems. In a very large system, such as speakers that would be used in an outdoor public address system, neodymium magnets prevent the speaker cabinets from becoming weight-prohibitive. In very small speakers, such as high-frequency tweeters, neodymium provides the drive needed to power the speaker while retaining a suitably small footprint.
