A novel 3D audio display system using radiated loudspeaker for future 3D multimodal communications

It is very important to develop 3D audio display systems compatible with future 3D visual displays in order to realize future 3D multimodal communications systems such as 3D television. In this paper, two 3D audio display systems using the radiated loudspeaker, that were developed by the authors, are described. In one system, the spherical radiated loudspeaker, which consists of 26 loudspeaker units and displays the solo player, was used. In this study, the spherical radiated loudspeaker displays two types of solo players. In the other system, the rectangular radiated loudspeaker, which consists of 157 loudspeaker units and displays the ensemble, was used. In this study, the rectangular radiated loudspeaker displays the string quartet.
