<p>The vibration generating device has a primary excitation coil (2) and a secondary excitation coil (7) that are provided for operating the primary magnetic circuit (3) and secondary magnetic circuit (8) respectively. The primary and secondary magnetic circuits are in yoke shaped and are provided with two legs (4,5,9,10) respectively. Two legs of the primary and secondary magnetic circuits are connected by connecting portions (6,11) respectively. A rotor (19) is mounted on a spring rod (12) that is arranged to oppose the primary and secondary magnetic circuits. An independent claim is included for vibration damping device.</p> |
