Voice Coil Motor Magnets Voice coil motors are a special form of linear motion motor, and also famous for its working principle which similar to the loudspeaker. Voice coil motor has a simple structure, low volume and noise, in the meanwhile, its specific thrust, acceleration, response speed and accuracy are also excellent. Besides, voice coil [...]
Small Neodymium Magnets in Smartphones Neodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case. These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus [...]
Voice Coil Motors (VCM), also called Voice Coil Actuators (VCA), is an electric motor consists of a magnet and yoke in conjunction with a coil. The magnet’s position, the type of magnet, the surrounding structure, etc., can influence the efficiency of the unit. Voice-Coil-Motors Some examples of applications of VCM Shaker/Vibrator Voice coil [...]
Magnet IT&Communication Application In computer hard disk drives, rare earth magnets are also used in the voice coil motors (VCM) that drive the heads that read and write the signals. Rare earth magnets are used in CD/DVD reading and writing heads (optic pickups) to accurate read the video and audio signals. Magnet IT&Communication Application [...]
Want free rare earth magnets? Got a dead hard drive? You're in business. What, you might be wondering, are super-strong magnets doing inside a magnetic storage device? You're meant to keep magnets away from your drives, aren't you? Well, yes, you are. A sufficiently strong magnetic field across the storage surfaces can destroy data in [...]
