1. A vibration suspension system for a transducer, the vibration suspension system comprising:
a movable device provided with a magnetic conductive material provided thereon
a coil configured to generate an altering magnetic field;
a permanent magnet configured to generate a static magnetic field; and
at least one suspension devices for providing a restoring force for a reciprocal vibration of the vibration suspension system,
wherein one end of the suspension device is fixed to the movable device, and the other end thereof is fixed to an inside of the transducer,
wherein a first end of the magnetic conductive material is located in a position corresponding to the alternating magnetic field in a vertical direction, and a second end opposite to the first end of the magnetic conductive material is located at a position corresponding to the static magnetic field in the vertical direction,
wherein the permanent magnet is disposed at a position corresponding to a center portion of the movable device, and the coil is disposed tat a position corresponding to an edge portion of the movable device.
