1. An audio reproducing apparatus, comprising:
- a plurality of speaker units whose radiation surfaces face outwardly away from one another; and
a directivity controlling means for controlling directivities of the plurality of speaker units so that a sum of the directivities of the plurality of speaker units becomes 0 so as to form at least one low sensitivity region where audio signals generated from a speaker of the plurality of speaker units not facing a listening position are suppressed and unable to be heard by a listener located at the listening position.

Abstract
An audio reproducing apparatus is disclosed. The audio reproducing apparatus includes a plurality of speaker units and a directivity controlling section. The radiation surfaces of the plurality of speaker units outwardly face. The directivity controlling section controls directivities of the plurality of speaker units so as to form one or a plurality of low sensitivity regions.

9. An audio reproducing apparatus, comprising:
-
a plurality of speaker units whose radiation surfaces face outwardly away from one another, wherein weighting factors for the plurality of speaker units are calculated so that the sum of the directivities of the plurality of speaker units becomes 0, and wherein audio signals multiplied by the weighting factors are supplied to the plurality of speaker units and reproduced therefrom so as to form at least one low sensitivity region where audio signals generated from a speaker of the plurality of speaker units not facing a listening position are suppressed and unable to be heard by a listener located at the listening position.

10. An audio reproducing method of reproducing audio signals from a plurality of speaker units, comprising the step of:
controlling directivities of the plurality of speaker units so that the sum of the directivities of the plurality of speaker units becomes 0 so as to form at least one of low sensitivity region where sound generated from a speaker of the plurality of speaker units not facing a listening position are suppressed and unable to be heard by a listener located at the listening position.

11. An audio reproducing apparatus, comprising:
-
a plurality of speaker units whose radiation surfaces face outwardly away from one another; and a directivity controlling section which controls directivities of the plurality of speaker units so that a sum of the directivities of the plurality of speaker units becomes 0 so as to form at least one of low sensitivity region where sound generated from a speaker of the plurality of speaker units not facing a listening position are suppressed and unable to be heard by a listener located at the listening position.
