Patent number: 11877121Abstract: This speaker system includes: a speaker device that is disposed outside a region of a projection surface on which a display surface of a display is projected, the speaker device functioning as a real sound source; and a reflector that has a reflection surface reflecting a sound output from the speaker device, the reflector localizing a sound image of a virtual sound source within the region of the projection surface. The reflector has an elliptical reflection surface in at least a part of the reflection surface. With this configuration, the sound output from the speaker device disposed outside the region of the projection surface is reflected on the reflector, and a sound image thereof is localized within the region of the projection surface, whereby it is possible to bring a display position of a video into alignment with an output position of the sound. Thus, a comfortable viewing state can be ensured for a viewer.Type: GrantFiled: October 12, 2020Date of Patent: January 16, 2024Assignee: Sony Group CorporationInventors: Kazunobu Ookuri, Kohei Asada, Masaki Kamata, Hiroyuki Shirakawa
