Patent number: 11962972Abstract: To enhance a sound image localization effect and to ensure a good viewing state in which an image or video and audio have a sense of unity. Provided is a display in which an image is displayed in a display surface, a rear cover disposed on a rear side of the display, a first speaker disposed between the display and the rear cover, and a second speaker disposed between the display and the rear cover and positioned higher than the first speaker. The second speaker outputs audio according to operation of a piezoelectric element, and has a higher audio output band than the first speaker. This enables a user to feel as if the audio is being output from the display being viewed, which enhances the sound image localization effect and ensures a good viewing state in which an image or video and audio have a sense of unity.Type: GrantFiled: November 21, 2019Date of Patent: April 16, 2024Assignee: SONY GROUP CORPORATIONInventors: Masahiro Takahashi, Tatsuya Sakata, Tetsuya Shiroishi, Shigemi Oguchi, Kazumasa Okamoto, Ryosuke Nakajima
