PROBLEM TO BE SOLVED: To provide a linear sound source loudspeaker effectively generating cylindrical waves, and to provide an audio/image display including the same. SOLUTION: The linear sound source loudspeaker includes: three or more magnets arranged on a line; a diaphragm arranged to extend along the arrangement direction of the magnets and face one-side magnetic poles of the magnets; yokes provided for the respective magnets, abutting on the other side magnetic poles of the magnets, and bent to surround the magnets toward the diaphragm; a frame for holding the magnets and the yokes and supporting the diaphragm in an edge part; and three or more voice coils arranged corresponding to the respective magnets, and fixed to a surface of the diaphragm on the side facing the magnets to interlink with magnetic flux formed by the magnets and the yokes.
