  • Patent number: 10996717
    Abstract: 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.

  • Patent number: 10880655
    Abstract: A method for operating a hearing apparatus system with at least one hearing apparatus uses a first sensor of the hearing apparatus to capture a first measured variable characteristic of an actual wearing situation. If the first measured variable and/or a variation over time derived therefrom satisfies at least one prescribed first criterion, it is inferred that the hearing apparatus has had a tumble. If the tumble is detected to have taken place, at least one further measured variable and/or a variation over time derived therefrom is captured, and the at least one further measured variable is used to ascertain whether the hearing apparatus is arranged on the head of a hearing device wearer after the tumble.
