Magnetic Materials in Voice Coil Motors (VCM)

Magnetic Materials in Voice Coil Motors (VCM) Voice coil motor, VCM is a special form of direct drive motor, which can directly convert electrical energy into linear motion mechanical energy. The principle is to put a cylindrical winding in a uniform air gap magnetic field, and the winding generates a magnetic field. , Drive the [...]

Understanding the Basics of a Voice Coil Actuator

Understanding the Basics of a Voice Coil Actuator A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor. The name “voice coil” comes from one of its historically first applications: vibrating the paper cone of a loudspeaker. They are currently used for a wide range [...]

What is Speaker Magnet

What is Speaker Magnet The neodymium speaker magnet produces a magnetic field, and the speaker’s voice coil motor is placed in the magnetic field. When the voice coil passes through the audio current, the current will be acted by the magnetic field, which causes the voice coil to vibrate, and drives the paper basin that [...]
