Neodymium iron boron magnet is a permanent magnet material made of neodymium, iron and boron and other rare earth elements. They have extremely high magnetic properties and are more powerful than other types of magnets such as ferrite magnets. This makes neodymium iron boron magnets widely used in consumer electronics, especially where compact and powerful magnetic solutions are needed.
In smartphones, neodymium iron boron magnets are used for a variety of functions, such as vibrating motors, speakers, microphones and sensors. These magnets help smartphones achieve high-quality audio output and precise sensor data, while keeping the device thin and compact. For example, the neodymium iron boron magnet in the vibration motor can produce a strong vibration effect, so that the phone can provide clear tactile feedback when the call or notification is received.
Earphones are another widely used neodymium iron boron magnets for consumer electronics. Whether it is a headset or an in-ear headset, neodymium iron boron magnets are used as magnets in the drive unit. Their high magnetic properties provide clear, high-fidelity audio while ensuring that the headphones are small and portable. Headphones using neodymium iron boron magnets can better restore the details and dynamic range of music, bringing users an immersive listening experience.
