Spearker Ferrite Magnet Round Ceramic Magnet for Speaker

Magnets are key parts of loudspeakers, speakers, and headphones. Different types of magnets produce varying ranges of tone qualities. The strength of speaker magnets ranges from 0.001 teslas to 1.5 teslas and varies with the size and type. Magnets used in headphones are not as strong as magnets used in loudspeakers. But, stronger speaker magnets must be used to reduce speaker size and have the same strength to produce the desired sound. 

Ceramic magnets or Permanent Ferrite Magnets are bulky in size, making them suitable for use in large drivers for mid-range to high-range woofers and subwoofers.  They can produce sounds better at louder speaker volumes.  They weigh heavily, which significantly increases the overall weight of the speakers using them.  They are also corrosion-resistant, making them suitable for damp environments such as marine sounder applications.  Without the presence of a stronger magnet around, ceramic magnets can maintain their magnetic strength for long periods.  Compared to Sintered Neodymium Magnets, ceramic magnets cost cheaper, which allows production in large quantities.  Generally, Ceramic Ferrite Magnet is favored when long service life and low cost are primary considerations.
