Permanent neodymium double loudspeaker magnet especially for loudspeaker motor, with xcellent resistance to demagnetization. Coated with black epoxy.

All speakers don't use magnets. Only magnetic speakers use a magnet to produce mechanical vibration (sound) through the interaction between the magnetic field created by the pulsating electronic signals passing through a coil suspended in the strong magnetic field of the magnet. Other types of speakers like piezo speakers (for example, buzzers in wrist watches don't use a magnet. Piezo speakers use the piezo electric effect. They generate mechanical vibration by applying an electric signal to a piezo electric crystal.


Due to the sizes of the magnet, there may be variations on pull strength. Please contact our customer service team for more information.
