Abstract:
1. A stereophonic sound reproducing system comprising: a stereophonic sound reproducing apparatus for providing a sound field space having the realism of a live performance to the listener by amplifying a plurality of input stereophonic sound signals by speakers corresponding to the stereophonic sound signals; at least a pair of right and left main speakers installed forward of the listening position and amplifying main signals as stereophonic sound signals corresponding to the speakers; and an integral surround speaker obtained by integrally forming a left surround speaker for generating the stereophonic sound by amplifying a surround signal as a stereophonic sound signal of a left-side component with respect to the listening position as a reference, and a right surround speaker for generating the stereophonic sound by amplifying a surround signal as the stereophonic sound signal of a right-side component with respect to the listening position as a reference, wherein the stereophonic sound reproducing apparatus comprises: a signal adjusting device, in the case where the integral surround speaker is installed in a position that makes arrangement asymmetrical with respect to the listening position as a center, which adjusts the frequency characteristic of a surround signal of a component of the side different from the side on which the integral surround speaker is asymmetrically installed on the basis of a transfer function for creating a sound image in a predetermined listening position; an adding device which adds a component of at least part of the adjusted surround signal to a main signal of the component of the side different from the side on which the integral surround speaker is asymmetrically installed; and an output device which outputs the resultant main signal to the corresponding main speaker and outputs at least part of the surround signal whose frequency characteristic is adjusted to the corresponding surround speaker, and wherein the integral surround speaker is installed separately from a pair of the right and left main speakers.
