Mobile Phone NdFeB Magnets

Mobile Phone NdFeB Magnets

In every phone, high-performance NdFeB magnets are used to two parts at least, one in phone vibration motor, the other is in miniature electro-acoustic device speaker.

On the picture, you can see the rare earth permanent magnets in vibration motor are disc sheet shape, and the in the center of the vibration motor used cylindrical holes of rare earth permanent magnets.

According to the report 19th July of Gartner, Well-known information technology research and advisory firm, global smart phone sales reached 1.4 billion sets at year of 2015. If an average of finished dosage of 2.5g each calculation, the annual NdFeB magnets demand will be about 3500 tons.

This is just the sintered NdFeB in the phone application, as well as printers, copiers, projectors, scanners, fax machines, audio tapes and other office supplies will be in great need of NdFeB.

Our NdFeB magnets are small, thin, high-speed, long life, high reliability, low noise and high accuracy. Almost of driving motor in the information-related devices such as printers are permanent magnet brushless DC motors. These permanent magnet brushless DC motor are using high-performance NdFeB magnets, thus the demand of rare earth permanent magnet material for is more and more.
