Electronics

In the electronics field, the core requirements for permanent magnet assemblies focus on “miniaturization, low power consumption, high magnetic flux density, and strong compatibility”. They need to fit the compact space and complex working environment of devices. They must not only achieve miniaturized and lightweight designs to meet the integration needs of products such as consumer electronics and automotive electronics, but also have high magnetic stability and low magnetic loss characteristics to avoid magnetic-field interference with the normal operation of electronic components, while complying with RoHS environmental compliance standards and having environmental adaptability such as vibration resistance and moisture resistance. They are widely used in key scenarios such as consumer electronics (magnetic circuit for mobile phone vibration motors, magnetic cores for wireless charging coils, drive magnets for TWS earphones, magnetic components for laptop cooling fans), automotive electronics (magnetic control modules for in-vehicle radar, permanent-magnet sensors for new energy vehicle electronic control systems, magnetic cores for in-vehicle chargers), IoT devices (magnetic switches for smart wearables, magnetic excitation units for sensors, smart home control modules), industrial electronics (magnetic drive components for precision instruments, magnetic positioning units for automation control equipment), and communication equipment (magnetic tuning components for base-station antennas, micro magnets for satellite communication equipment). The core advantages are particularly prominent: first, the miniaturized integrated design can be seamlessly embedded into compact electronic devices, releasing high magnetic flux density performance in limited space and supporting the development trend toward smaller and thinner devices; second, low magnetic loss and high magnetic efficiency help reduce device energy consumption, extend the battery life of consumer electronics, and improve the energy efficiency of automotive electronics; third, strong electromagnetic compatibility and stable magnetic performance can avoid magnetic-field interference, ensuring signal transmission and operating accuracy of electronic devices; fourth, environmental compliance and suitability for mass production meet the electronics industry’s needs for scaling and green development, while also supporting customization of magnetic performance parameters, structural dimensions, and installation methods according to device models, precisely matching the personalized needs of different electronic devices.
