Sintered NdFeB Magnets for Consumer Electronics

Product Overview

Sintered NdFeB magnets for consumer electronics are high-performance permanent magnets built for compact, efficient, and high-precision electronic devices. The sintering process delivers high remanence, high coercivity, and excellent dimensional stability, supporting strong magnetic fields in small form factors.

Ningbo Jinlun Magnet Technology Co., Ltd. produces these magnets with internationally advanced permanent magnet production equipment, more than 30 years of industry experience, and an annual production capacity of 8,000 tons for various high-performance magnets.

Key Features

• High magnetic strength – supports device miniaturization while maintaining magnetic force.
• Compact size – suitable for small, integrated components such as motors, actuators, sensors, and speakers.
• Thermal and mechanical stability – maintains performance under varying temperature and operational conditions.
• Precise tolerances – sintered manufacturing ensures uniformity and repeatability across batches.
• Long-term reliability – high coercivity reduces demagnetization risk from external magnetic fields or mechanical stress.

Applications

Sintered NdFeB magnets are used in devices that rely on magnetic interactions for mechanical or sensing functions:

• Micro motors – generate torque in small DC or brushless motors.
• Speakers and audio devices – interact with voice coils to produce sound.
• Sensors and actuators – enable position detection, motion control, or haptic feedback.
• Data storage devices – used in small-scale magnetic actuators or motors for disk drives.

Typical examples

• Smartphone motors and haptics – vibration motors and haptic feedback systems.
• Compact audio devices – speakers, earphones, and miniature sound transducers.
• Consumer robotics and drones – small motors for drones, robotic toys, and household robots.
• Hard drives and storage systems – voice coil actuators for positioning read/write heads.
• Wearable electronics – motorized components and sensors in smartwatches, fitness trackers, and medical devices.

Product examples named in the source include speaker magnets, wireless charging magnets, computer disk drives magnets, headset magnets, and vibrating motor magnets.
