Sound producing method and sound producing apparatus
First Claim
1. A sound producing apparatus adapted for setting a virtual sound space corresponding to a virtual space displayed on a display unit to produce a sound, the apparatus comprising:
- underlying sound signal generating means for generating, on the basis of an underlying sound parameter, an underlying sound signal indicating situations of a place at a position of a virtual user within said virtual space;
ornamental sound signal generating means for generating, on the basis of an ornamental sound parameter, an ornamental sound signal set at an object disposed within the virtual space; and
sound producing means for producing a sound on the basis of at least the underlying sound signal and the ornamental sound signal that the underlying sound signal generating means and the ornamental sound signal generating means respectively generate.

Abstract
In a sound producing apparatus and a sound producing method of this invention, at least underlying sound representing situations of the place within virtually actualized space and ornamental sound corresponding to object within the virtually actualized space which is not independent of presence or absence of display on a display unit are produced to set virtual sound space corresponding to the virtually actualized space displayed on the display unit. Thus, speech (sound) can be utilized as means for grasping spatial information as in the actual world within the virtually actualized space, and offer of information utilizing speech (sound) can be made. In addition, the advertisement effect can be also increased.
