The Shaker:
The mode of function of a shaker corresponds to that of a loudspeaker. The vibration movement is generated by the interaction of electric current passing through the plunger coil and a magnetic field. The force used to accelerate the moving element comprised of a ribbed body and the wrapped plunger coil is proportional to the coil current, the magnetic flux density, and the length of
conductor in the magnetic field. The vibration level of shaker can therefore be controlled by electric current intensity.
