Sound field supporting device and sound field supporting system

Abstract

Listening position is disposed on or in the proximity of the plane same as that of the diaphragm of a planar loudspeaker. An audio sound emitted from a main loudspeaker being a sound source is received by a microphone of a sound field supporting device to be outputted from the planar loudspeaker as a sound wave according to a signal of an indirect sound component generated in a DSP. There are few sounds that directly reach the listening position from the planar loudspeaker, resulting in that reflected sounds reflected by wall surfaces, a ceiling, and the like in the room mainly reach the listening position. 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 itself, and a sound field in which the indirect sound components resonate in the entire room can be provided.
