2.3) Theory of Operation
DS-PM-20 is an electro-magnetic actuator. Electro-magnetic actuators are
basically voice coils consisting of a permanent magnet and coil. The moving
element can be the coil or the magnet depending on the design requirements.
The moving element is usually suspended by an elastic membrane.
DS-PM-20 has a moving coil (driving coil) whose current is controlled for
vibration generation. The stationary magnetic field is produced by a
permanent magnet.
