Zusammenfassung:PROBLEM TO BE SOLVED: To provide a horn which can ensure high sound pressure by increasing the suction force of a fixed core without increasing a current value passing through an exciting coil.SOLUTION: A horn comprises a moving core 7 fixed to a diaphragm, a fixed core 9 which is coaxial with the moving core 7 and disposed so as to form a predetermined air gap G, an exciting coil 15 which forms a coil flux F (a first flux) capable of sucking the moving core 7 toward the fixed core 9 side, and a magnet 10 which forms a magnet flux Mg (a second flux)in a direction of the coil flux F between the moving core 7 and the fixed core 9.
