    摘要： An audio device is described which comprises a housing holding electronic components and having a face being substantially covered by a layer of transparent material. The audio device has a display comprising a layer of display material supported under at least part of the layer of transparent material; and at least one display actuating element in the housing configured to flex the display and the layer of transparent material to generate sound waves. There is at least one air cavity formed between the layer of display material and the housing; and an entrance formed in the layer of transparent material to allow air to pass between the air cavity and an exterior of the device.

    摘要： A compressed skins-tensioned core structure (400) includes a first surface region (410); a second surface region (450); a core (430) between the first surface region (410) and the second surface region (450); a first transition region (420) continuous with the first surface region (410) at a side, and continuous with the core (430) at another side; and a second transition region (440) continuous with the core (430) at a side, and continuous with the second surface region (450) at another side, wherein each of the first surface region (410), the second surface region (450), the core (430), the first transition region (420) and the second transition region (440) is formed of a substantially homogeneous amorphous material; each of the first surface region (410) and the second surface region (450) exhibits an internal compressive stress, the core (430) exhibits an internal tensile stress, and each of the first transition region (420) and the second transition region (440) exhibits a stress gradient from the internal compressive stress to the internal tensile stress.
