PROBLEM TO BE SOLVED: To provide a sound-reproducing device by which a listener can form an optimal surround sound field by easily correcting the output angle of a sound beam, according to the setting of a hearing position of the sound reproducing device, and to provide a sound beam reflection position correcting method for the sound-reproducing device.;SOLUTION: In this sound-reproducing device 1, when it is installed in a room for reproducing surround sound, an operating part 4 receives the inputs of installation position information of a speaker array 8 and hearing position information of the listener U, a system control part 2 calculates the output angle of sound beams of a rear channel (SLch, SRch) for outputting the sound beams to the listener U and a first point of reflection for first reflecting the sound beams to the surface of a wall to determines whether the point is located ahead of the listener U. When the first point of reflection is located in front of the listener U, positions are changed so that sound of a rear channel existing at the back of the position, where the first point of reflection is obtained by calculation is reflected to enable the listener U to listen to the sound from the right beside the listener U or behind.;COPYRIGHT: (C)2006,JPO&NCIPI
