Is the magnet used in the speaker sintered NdFeB or bonded NdFeB?

With the advancement of technology, the range of speaker speakers is getting wider and wider. loudspeaker are used from mobile phone headphones, MP3 headphones to car audio and so on. Generally speaking, the magnets used in speakers/horn are sintered NdFeB or bonded NdFeb magnets. What about boron?

The amount of horn speakers is increasing, and the industry insiders will use the magnets in the speakers, called the horn magnets, or horn magnets for short. For NdFeB tweeters, generally only sintered NdFeB can be used. The main reason is that the sintered NdFeB has higher remanence and magnetic energy product than the bonded NdFeB, which can make the speaker have a good sound effect. If NdFeB is used for bonding, the db value of the speaker will basically fail to meet the design requirements.

In addition, if there are higher requirements for the working conditions or working environment of the speaker, it is necessary to further consider the performance of the magnet and the requirements of the working temperature in the selection of NdFeB magnets.

The specifications of the speaker magnet include: φ6*1, φ6*1.5, φ6*5, φ6.5*1.5, φ6.5*φ, 2*1.5, φ12*1.5, φ12.5*1.2, etc. The medium hole NdFeB magnet needs to be determined according to the required specifications of the speaker.

In addition to NdFeB materials, ferrite materials are also commonly used in speaker speakers (speakers), such as ferrite ring magnets, with various specifications.
