Abstract
Provided is a loudspeaker system capable of easily determining control parameters for controlling the directional characteristics of a speaker set including two or more speaker units. The loudspeaker system is configured to include: a speaker setincluding two or more speaker units; a cameraadapted to photograph an acoustic space of the speaker set; a monitoradapted to display a camera imagephotographed by the camera; and a directional control parameter generating partadapted to generate directional control parameters providing the directional characteristics of the speaker set. The directional control parameter generating partsincludes: a target position designation partadapted to, on the basis of user operations, designate target positionson the camera image; a directional control angle calculation partadapted to, on the basis of the target positions, obtain directional control angles θ with respect to a front direction of the speaker set; and a directional control parameter determination partadapted to, on the basis of the directional control angles θ, determine the directional control parameters.
