PROBLEM TO BE SOLVED: To provide a speaker device that can clearly localize a sound source, using localization by a virtual sound source while taking advantage of a characteristic of a sound beam.SOLUTION: The speaker device is configured to: detect level differences by which a sound beam of each channel reaches a listening position and set based on the detected level differences a gain of a gain adjustment section 43SR higher than gains of the other level adjustment sections; set level of a localization adding section of an SR channel higher than level of the other channels so as to heighten effect on localization addition by a virtual sound source; adjust level ratios between each channel of a localization adding section 42 and each channel for the sound beam; and synthesize audio signals to output audio signals VL and VR to a correction section 51. The correction section 51 performs filter processing and outputs audio signals VLD, VLC, VRC and VRD, which are inputted to woofers 33L and 33R through synthesizing sections 52L and 52R, delay processing portions 60L and 60R and an addition processing section 32. |
