Sound reproducing system and sound reproducing method
First Claim
1. A sound reproducing system to reproduce audio signals of a plurality of channels including a first channel in which a reproduced sound image is localized in a position in a front direction of a listener, the sound reproducing system comprising:
- a first speaker that is supplied with first audio signals of the first channel and that is placed so that a first reproduced sound image generated by the first audio signals of the first channel is localized in a position in the front direction of the listener;
a pair of second speakers that are supplied with second audio signals on which a virtual sound source process is performed so that a second reproduced sound image is localized in a predetermined position;
virtual sound source processing means for performing the virtual sound source process on the audio signals of the plurality of channels so as to generate the second audio signals to be supplied to the second speakers;
volume detecting means for detecting a volume of the first channel from the first audio signals of the first channel and detecting volumes of channels other than the first channel from other audio signals of the other channels;
volume comparing means for comparing the volume of the first channel with each of the volumes of the other channels detected by the volume detecting means; and
control means for controlling the gains of the first audio signals of the first channel and the other channels based on a comparison result generated by the volume comparing means;
wherein the second speakers are held by holding means at predetermined positions near the ears of the listener, and wherein speaker units of the second speakers are not attached to a baffle plate so that sound components output from front and rear sides of vibrating plates of the speaker units can be added to each other.

9. A sound reproducing method in a sound reproducing system including:
-
a first speaker that is supplied with first audio signals of a first channel among audio signals of a plurality of channels including the first channel in which a reproduced sound image is localized in a position in a front direction of a listener and that is placed so that a first reproduced sound image generated by the first audio signals of the first channel is localized in a position in the front direction of the listener; a pair of second speakers that are supplied with second audio signals on which a virtual sound source process is performed so that a second reproduced sound image is localized at a predetermined position; wherein speaker units of the second speakers are not attached to baffle plate so that sound components output from front and rear sides of vibrating plates of the speaker units can be added to one another; and virtual sound source processing means for performing the virtual sound source process on the audio signals of the plurality of channels so as to generate the second audio signals to be supplied to the second speakers; the sound reproducing method comprising the steps of; comparing the volume of the first audio signals of the first channel to be supplied to the first speaker with each of the volumes of the other audio signals of the other channels, the comparison being performed by volume comparing means of the sound reproducing system; and controlling gains of the first audio signals of the first channel and the other channels based on a comparison result generated in the volume comparing step.
