| Outline of Final Research Achievements |
A 3D acoustic hologram was constructed with a parametric loudspeaker that focuses an emitted sound wave to construct a sound image in a targeted area. The flexible parametric loudspeaker was first developed by enabling the surface of the loudspeaker to be freely transformed. The 3D acoustic hologram was then realized by separating the carrier and sideband waves of a sound wave with multiple flexible parametric loudspeakers. The application of the hologram was also investigated through social implementation experiments, and we researched the integrated development of a hologram that could construct a sound image in a targeted area.
