VCM (Camera focus mechanism)
Voice coil motors are normally used to drive audio speakers. VCM is also used in other applications where precision is important.
Autofocus camera typically use Voice Coil Motors (VCMs) because VCMs are very fast and precise over short distances, and they are designed to move the speaker dome the same way a camera lens moves. Each camera's autofocus motor uses 2-4 magnets.
Consumer electronics: Electronics are one of the traditional applications of high-performance neodymium magnets. Taking smartphones as an example, there are over 10 components using neodymium magnets,
For example, microphones, micro speakers/receivers, vibration motors, wireless chargers, Bluetooth headphones, phone camera focusing, sensors, and so on. With the progress of science and technology, more and more smartphone accessories are made of neodymium magnets.
Below are some common shapes of neodymium magnets. If you need to customize special shapes, please contact us and we will customize the best solution for you!
Export Standard Cartons are supplied with foam well protected. We can make the packages according to customer's request.
Standard sea and air packages are available.

Permanent Magnets Properties Chart
*Shine Magnetics made the mass production of neodymium magnet(N52,N52M,N52H, N48SH, N45UH, N40EH, 33AH). We owns the most complete set of manufacturing facilities for timely producing tailored magnets that customer need.
*The highest grade of shine neodymium magnets retain a max working temperature of 220℃.
*After 168 hours of HAST test ( 2atm, 100%RH, 120℃) on the no coating N45SH NdFeB magnet, the weight loss is less than 3 mg/cm³. We always produce NdFeB magnets with high anti corrosion characters and low temperature coefficiency.
