Ceramic Magnet Speaker

As the voice coil s effect lowers the available magnetic field of the alnico magnet the speaker becomes less efficient and the voice coil moves less.

Brief introduction of speaker magnets. A ferrite is a ceramic material made by mixing and firing large proportions of iron iii oxide fe 2 o 3 rust blended with small proportions of one or more additional metallic elements such as barium manganese nickel and zinc. Ceramic magnets are made of strontium ferrite which a much cheaper and more abundant material.

Speakers with higher power ratings generally have larger magnets since the wire in the voice coil is a larger diameter is heavier and requires a larger magnet to get the magnetic energy required to get the heavier voice coil moving to achieve high frequency response. The first crop of speakers in the early 1950s used alnico magnets which is why some people say they sound more vintage than speakers built with ceramic magnets. Alnico speakers compress at high volumes. 4 75 no cover 5 375 with cover cutout size.

If you are comparing speakers that have the same magnetic flux but generated from different magnet compositions you probably won t notice a difference in tonality. They are electrically nonconductive meaning that they are insulators and ferrimagnetic meaning they can easily be magnetized or attracted to a magnet. The permanent magnets used in speakers are called speaker magnets.
