Zusammenfassung:The utility model discloses a magnetic circuit for narrow-narrow loudspeaker, which comprises an upper board, a slab-column and a magnet; wherein the magnet takes a shape of a cuboid, a rectangle or a runway; two cuboid-shaped neodymium iron boron magnets are spliced between the top of the upper board and the bottom of the slab-column and also a rectangle neodymium iron boron magnet or a runway-shaped neodymium iron boron magnet can be spliced between the top of the upper board and the bottom of the slab-column and the magnetic circuit can be formed in both ways. The whole profile size is only 33 multiplied by 22 multiplied by 10mm, the maximum power that can be provided is 16W and the magnetic field is uniform. The utility model is characterized in that the intensity of magnetic field of the magnetic air gap is stronger, the efficiency of electroacoustic conversion is high, the utility model charges magnetic conveniently, the sensitivity is high, etc. The circuit breaks through the limitation of the width of the traditional loudspeaker magnetic circuit and is a magnetic circuit for narrow-narrow loudspeaker with advanced technology.
