Abstract:
The present disclosure discloses a vibration suspension system for a transducer, which comprises at least one movable device provided with a magnetic conductive material, at least a part of the magnetic conductive material being arranged in an area where an alternating magnetic field overlaps with a static magnetic field, so that the static magnetic field and the alternating magnetic field are converged, and a magnetic field force generated by the interaction between the static magnetic field and the alternating magnetic field being applied to the magnetic conductive material, so as to drive the vibration suspension system to move; and at least one suspension device comprising an elastic recovery device for providing a restoring force for a reciprocal vibration of the vibration suspension system, one end of the elastic recovery device being fix to the movable device and the other end thereof being fixed to the inside of the transducer.
