The invention provides a planar diaphragm
loudspeaker with an asynchronous magnetic
reflux structure, which comprises at least one upper
magnet support frame, at least one lower
magnet support frame,at least one lower
magnet support frame and at least one lower magnet support frame, a first supporting mechanism and a second supporting mechanism are arranged below the upper magnet set. A
voice coil diaphragm mechanism is installed between the first support mechanism and the second support mechanism. At least one lower magnet support frame is further arranged below the second support mechanism;a lower magnet set is fixed to the inner side of the lower magnet supporting frame, a first conductive
metal sheet and a second conductive
metal sheet are arranged below the lower magnet set, the upper magnet set comprises a plurality of upper magnets, the lower magnet set comprises a plurality of lower magnets, the number of the upper magnets is different from that of the lower magnets, and theupper magnets and the lower magnets are arranged in a staggered mode. According to the planar diaphragm
loudspeaker, the
diameter, the size and the weight of a planar diaphragm
loudspeaker body structure can be effectively reduced, the sounding quality is remarkably improved, the overall structure of the loudspeaker is optimized, and the size
miniaturization is realized.
