摘要： A loudspeaker having a repulsion magnetic circuit capable of suppressing negative magnetic fluxes. The loudspeaker has magnets with the same poles being faced each other and an outer magnet magnetized in a direction different from the counter magnets is disposed outside of the counter magnets. A voice coil containing magnetic material is disposed outside of a magnet magnetized in a radial direction from the inner wall to the outer wall of the magnet, or outside of a magnet assembled by magnet pieces magnetized in a predetermined direction and arranged to take the same magnetization direction.
