Magnetic-potential loudspeaker and electronic device using the same

A magnetic-potential loudspeaker, comprising:

• a movable sound generating device provided with a magnetic conductive material,
• wherein at least a part of the magnetic conductive material is 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 an interaction between the static magnetic field and the alternating magnetic field is applied to the magnetic conductive material so as to drive the movable sound generating device to move,
• wherein the movable sound generating device further comprises:
• a diaphragm and a rigidity adjusting portion arranged on at least one surface of the diaphragm;
• and
• at least one suspension device, wherein the suspension device comprises an elastic recovery device for providing a restoring force for a reciprocal vibration of the movable sound generating device,
• wherein an inner fixing portion of the elastic recovery device is fixed to the diaphragm, an outer fixing portion of the elastic recovery device is fixed to an inside of the magnetic-potential loudspeaker, and
• wherein the rigidity adjusting portion, the magnetic conductive material, and the inner fixing portion of the elastic recovery device are staggered.
