※ Ferro fluid is shown as being applied only to magnetic field

- Vibration force

   The force of ‘Moving mass’ moves vertical and vibration

- Damping force

   The force preventing 'Moving mass' against the motor cover.

   We called Touch(Noise) as bump and make snap.

- Dispersion

   Scattering magnetic fluid by vibration

Up and down vibration motion
