Vibration motor
Abstract:
A vibration motor comprises a permanent magnet supported by a spring and an electromagnet. The electromagnet generates an alternating second magnetic field which exerts a torque on the permanent magnet and causes said permanent magnet to rotate and vibrate. The supporting spring transfers the vibration energy from the permanent magnet to the housing and ultimately to the user.
