PROBLEM TO BE SOLVED: To correct a sound wave path length in a sound channel of a throat part for sound wave path length correction with a simple structure. SOLUTION: Disclosed is a sound wave path length correcting structure for a speaker system equipped with a sound source 11 which outputs a sound wave; a horn 12 having the throat part 13 for sound wave path length correction which corrects the sound wave path length in the sound channel 13g by inputting a sound wave from an entrance opening 13a connected to the sound source 11 and radiating it from a rectangular exit opening 13b and a horn part 14 for sound enlargement which enlarges the sound wave radiated from the exit opening 13b. The throat part 13 for sound wave path length correction has the sound channel 13g formed so that the wave face of the sound wave radiated from the rectangular exit opening 13b to the horn part 14 for sound enlargement may be in a rectangular plane shape, convex surface shape, or concave surface shape without forming a multiple-stage branch path structure in the sound channel 13g.
