Is the magnet that horn loudspeaker uses sintered neodymium iron boron or bond neodymium iron boron?
As the advance of science and technology, the range of loudspeaker is bigger and bigger, used loudspeaker to wait a moment to car acoustics from mobile phone earphone, MP3 earphone, so the magnet that general loudspeaker speaker uses is sintered neodymium-iron boron or bond neodymium-iron boron?
The dosage of loudspeaker is bigger and bigger, the personage inside course of study will use the magnet in loudspeaker, call loudspeaker magnet, abbreviation loudspeaker magnetism. NdFeB tweeter, generally only sintered NdFeB. The main reason is that sintered NdFeB has a higher magnetic residual and magnetic energy product than bonded NdFeB, which can make the speaker have a very good sound effect. If you use bonded NdFeB, the DB value of the speaker can not meet the design requirements.
In addition, if the working conditions or working environment of the horn have higher requirements, the selection of NdFeB magnet also needs to further consider the magnet performance and working temperature requirements.
The horn magnetic specifications include: Φ6 *1, Φ6 *1.5, Φ6 *5, Φ6.5 *1.5, Φ6.5 * 2*1.5, Φ12 *1.5, Φ12.5 *1.2, etc., also including a variety of holes in the hole NdFeB magnets, the specific needs according to the specifications of the horn to set.
In addition to NdFeB material, speakers (speakers) also commonly used on the ferrite material, such as ferrite ring magnet, specifications are diverse.
