Sound speakers, from the smallest to powerful have permanent magnets situated just behind the center of the sound cone. In addition, the magnet interacts with a non-permanent magnetic field from an electrical coil. In addition, pushing / pulling forces move the speaker cone fast in and out, creating sound. Today, magnet manufacturers in China use various kinds of magnets to suit speakers of dissimilar sizes and to get a range of tone.

1. Alnico

It is an alloy of nickel, cobalt and aluminum and is the magnetic material employed in the original speakers in all types of vintage amps. In addition, it creates a classic tone that is heated and sweeter at lower volumes, which several sounds players feel reacts quicker to the touch. Thus magnet was used for years due to its strong magnetic field, but once this alloy became little pricey, lots of manufacturers of speaker magnet in China chosen for speakers with the less costly ceramic magnets.

2. Ceramic magnets

They were created as an inexpensive option to Alnico and have the benefit of being more adaptable to a broad range of tones. Additionally, speakers with ceramic magnets have a tendency to weigh more, but usually handle more power and sound great at high volumes.

3. Samarium Cobalt

As samarium cobalt costs more, so speaker manufacturers of China don’t utilize this material usually. Samarium Cobalt has most of the strength of neodymium at the same time as having better heat resistance. It tends to be as breakable as neodymium, but stands up better to corrosion and moisture.

4. Neodymium:

The latest development in speaker magnet material and is not as costly as Alnico, but little more expensive than ceramic magnet speakers. Neodymium has the benefits of both weighing about 50 percent less than other speakers as well as having great magnetic properties. Apart from, speakers created from neodymium meet a player’s touch like Alnicos and have a well-balanced frequency response.

5. Ferrite

Magnets made of ferrite also known as ceramic magnets are inexpensive and break more easily compared to metal magnets. However, they maintain their magnetic strength sound over time, so don’t bring a stronger neodymium magnet close.

In addition, their greater weight creates speaker systems heavier, a drawback for moveable speakers and guitar amplifiers. Remember, speakers with ferrite magnets be likely to sound better when you played louder.Therefore, the next time you purchase a speaker, focus on to the magnet and its influence on the sound is bigger than you think.
