Horn on the coil around the magnet, the speaker's working principle is the use of the acoustic signal into electrical signals, converted into acoustic signals to be transmitted. The magnet is here to play an important role.
When our voice enters the speaker, a specific, changing current will cause the coil to magnetically create a regular attraction or repulsion movement with the magnet, which vibrates the cone and amplifies the sound.
Horn speakers are ordinary ferrite magnets and neodymium iron boron magnets, but the general NdFeB magnets used more points, ordinary ferrite magnets are generally mainly used in low-grade headphones, neodymium iron boron magnets For high-end headphones, the sound quality is very good, good elasticity, good detail, good voice quality, sound field positioning accuracy. NdFeB horn magnetic main specifications are: φ6 * 1, φ6 * 1.5, φ6 * 1.2, φ6.5 * 1.5, φ6.5 * φ2 * 1.5, φ12 * 1.5, φ12.5 * 1.2, etc., the figures are For the millimeter.
Therefore, the magnet's role is to aid vibration.
