Title:
ACOUSTIC CONTROL SYSTEM AND ACOUSTIC CONTROL INTERFACE FOR HORIZONTAL ARRAY TYPE SOUND PLAYBACK APPARATUS USING WAVE FIELD SYNTHESIS
Document Type and Number:
WIPO Patent Application WO/2021/060600
Kind Code:
A1
Abstract:
The present invention relates to an acoustic control system and an acoustic control interface for a horizontal array type sound playback apparatus that comprises a plurality of speaker modules and uses wave field synthesis, the acoustic control system comprising: at least one signal processing device, which generates a driving signal for controlling each speaker module of the horizontal array type sound playback apparatus, so as to apply the driving signal to the horizontal array type sound playback apparatus; and a central control device for controlling the signal processing device, wherein the sound radiated from the horizontal array type sound playback apparatus in response to the driving signal can be radiated by forming a planar sound radiation surface while at least some of the sounds respectively radiated from the speaker modules overlap.
