Abstract

PURPOSE:To obtain a stereophonic reproducing sound excellent in solid effect, by using horn pipes which are different in length and shape, together with suitable speakers to them and usual pipes, and obtaining resonance sounds which are different in the frequency peak. CONSTITUTION:The pipes 1, 2, 3 which are different in shape, length and direction are fixed on the upper face of the closed box 17 by making holes on the box, and the sounds uttered from the speakers 4, 6, 7 which are incorporated in these pipes make each pipe resonate. The plate 5 by which these pipes are fixed in connected to the rotary plate 12 and the motor 13 by the connecting bar 11. And each pipe provided on the plate 5 repeats the piston motion to the right and left by means of rotation of the motor 13, and the sound is widely propagated to the right and left.
