Abstract
A coaxial loudspeaker with two magnets and three units is provided, in a conductive magnet bowl of which a magnetic circle body is equipped. A hollow piston shape conductive magnet core column body passes through a center cylinder hole of the magnetic circle body and arrives at center hole of the bottom of the conductive magnet bowl. A bottom face of column capital is connected to the magnetic circle body. And a small magnetic circle body, a conductive magnet polar plate circle and a high tone or super high tone diaphragm voice coil with a center hole which are constituents of a high tone or super high tone unit are equipped in groove hole of the column capital and on the column capital. The conductive magnet bowl, magnetic circle body, conductive magnet core column and a high tone or middle tone diaphragm voice coil are constituents of a high tone or middle tone unit. A low tone cone frame is connected to the surface of the conductive magnet bowl port. The upper side of a low tone voice coil is connected with the cone and the down side is located at the magnetic air gap forming between the internal wall of the conductive magnet bowl and the conductive magnet core column, which constituents a low tone unit. The coaxial loudspeaker with two magnets and three units of the utility model has a compact structure which is ingenious and reasonable. The upper low tone unit and the bottom high tone or middle tone unit share one magnet, which saves materials and lowers the manufacturing cost.
