Listening position (100) is disposed on the plane same as that of the diaphragm of a planar loudspeaker (13) (or in the proximity of the plane). An audio sound emitted from a main loudspeaker (51) being a sound source is received by a microphone (11) of a sound field supporting device (1) to be outputted from the planar loudspeaker (13) as a sound wave according to a signal of an indirect sound component generated in a DSP (12). There are few sounds that directly reach the listening position (100) from the planar loudspeaker (13) (namely direct sounds), resulting in that reflected sounds reflected by wall surfaces, a ceiling, and the like in the room mainly reach the listening position (100). Accordingly, a user existing at the listening position hears mainly the indirect sound components reflected by the wall surfaces without feeling localization of the planar loudspeaker (13) itself, and a sound field in which the indirect sound components resonate in the entire room can be provided. |
