Patent number: 11966261Abstract: In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.Type: GrantFiled: September 20, 2022Date of Patent: April 23, 2024Assignee: Google LLCInventors: James Nelson Castro, Carl Alexander Cepress, Liang Ching Tseng, Darren Torrie, Frances Maria Hui Hong Kwee, Rex Pinegar Price

Patent number: 11874707Abstract: This application is directed to a display assistant device that acts as a voice-activated user interface device. The display assistant device includes a base, a screen and a speaker. The base is configured for sitting on a surface. The screen has a rear surface and is supported by the base at the rear surface. A bottom edge of the screen is configured to be held above the surface by a predefined height, and the base is substantially hidden behind the screen from a front view of the display assistant device. The speaker is concealed inside the base and configured to project sound substantially towards the front view of the display assistant device.Type: GrantFiled: March 3, 2023Date of Patent: January 16, 2024Assignee: Google LLCInventors: James Castro, Marc Davidson, Chih-Min Chien, Daniel Corbalan, Carl Cepress, Liang Ching Tseng
