Workshop of Headphone and Earphone speaker ferrite magnet
Type
Anisotropic ferrite magnet or Isotropic ferrite magnet
The Advantage and difference between Anisotropic ferrite magnet and Isotropic ferrite magnet.
Due to the difference of production technology, Isotropic ferrite magnet have lower property ,but they can magnetize through to every side of magnet while Anisotropic ferrite magnet have higher property, but they only can magnetize through pre-designed magnet side.
How does Headphone and earphone works with magnet inside ?
Headphones are basically tiny speakers, which use an electromagnet to vibrate air and create sound. Various styles of headphones will use different technology and different magnets; however, the basic principle remains the same.
Essentially, headphones work through pulses of electricity that pass through the coil of the electromagnet, which cause the magnetic field to rapidly change. The magnetic field is attracted to and repelled from the permanent magnet found inside of the device. This causes vibrations back and forth, which results in sound.
