Permanent magnet components have extensive and critical applications in the field of electronic devices. In hard disk drives, hard disk manufacturers require a stable and efficient way to drive the magnetic head for data reading and writing. For this purpose, permanent magnet components are utilized in voice coil motors. These motors use neodymium iron boron permanent magnets with high magnetic energy product to generate a stable magnetic field. They are manufactured and precisely assembled through processes such as powder metallurgy. The quality is guaranteed by strict magnetic performance tests and simulated environment operation tests to meet the high-performance, high-reliability reading, writing, and seek requirements of hard disks. In smartphones, manufacturers expect functional modules to be miniaturized, efficient, and low-power. Specifically, in the camera anti - shake module, permanent magnet components cooperate with electromagnetic coils to stabilize the camera, optimize the magnetic field distribution during wireless charging, and are manufactured through micro-machining and integrated design. The quality is guaranteed by tests such as vibration, charging efficiency, and high temperature resistance to achieve good anti-shake effects and efficient wireless charging. In the tablet computer field, in order to improve the user experience, manufacturers install permanent magnetic components in the corresponding positions of the tablet, pen, and protective cover for the smart pen adsorption and charging and the tablet protective cover automatic adsorption functions. Small high-magnetic materials are used for installation through precision technology. After tests on adsorption firmness, charging stability, protective cover adsorption effect and durability, the smart pen can be accurately adsorbed and charged, and the protective cover can be easily used, meeting the diverse needs of electronic devices with different functions and lightweight design trends.
