Large Ceramic Ferrite Speaker Magnet for Headphone
Speaker power is dominated by the power consumption of coin. Speaker magnets use the same specifications and same magnetic material, but different in amounts of magnetization, the speaker power, sensitivity and transient expression are also different. It is not simply think that the larger the diameter the better the speaker magnet.
The variational electrical current enter into speaker, the magnet becomes a electromagnet.
With the changing of the current direction, the electromagnet is also kept moving back and forth because of the force movement of energized conductor in a magnetic field, which is also drive the cone vibrating. The sound of speaker is produced.

Qianglian Magnetics has ferrite speaker magnet, NdFeB speaker magnet for sale, which are usually ring magnets, or disc magnets like φ6 * 1mm, φ6 * 1.5mm, φ6 * 5mm, φ6.5 * 1.5mm, φ6.5 * φ2 * 1.5mm, φ12 * 1.5mm, φ12.5 * 1.2mm. The coating is usually galvanized, but according to environmental protection and many different requirements, the magnets can be coated in environmentally friendly zinc plating. The speaker magnets are widely used in louder speakers, receivers, microphones, alarm, stage audio, car audio and so on.

Here are the four styles of audio loundspeaker magnets:

1. Neodymium or NdFeB Ring Magnets

Neo speakers have a number of advantages over conventional ceramic magnet speakers. They have a high output to weight ratio which makes them ideal for a number of portable applications. Typically neodymium magnets are capable of generating high flux levels in a transducers magnetic gap which increases efficiency and lowers distortion. Most neodymium speakers are naturally video shielded by design. Speakers with wide bandwidth and high excursion capabilties are more easily produced with neodymium magnets. They also have a high saturation magnitization so the potentional of storing large amounts of energy is possible. For more information please contact us at jackhuang@qianglianmagnetic.com
