  • Patent number: 10009683
    Abstract: The present disclosure relates to a display device for generating sound by directly vibrating a display panel thereof, which includes a display panel connected to a surface of the display panel and configured to display an image; and a sound generating actuator, which is fixed to a support structure of the display panel and attached to the display panel to directly vibrate the display panel. In the display device, the progressing direction of the sound coincides with the image output direction in the display device. Therefore, sound localization or sound output characteristics of the display device or set apparatus can be improved, and a separate speaker is not required, the mechanism of the set apparatus can be easily designed, and a thickness thereof can be easily reduced.

  • Patent number: 9756749
    Abstract: An electronic apparatus is disclosed. In one embodiment, an electronic apparatus comprises a display, a cover member, a piezoelectric vibrating element, a controller, a housing, a bonding material, and an intervening member. The bonding material between the housing and a peripheral end of an inner surface of the cover member is configured to bond the housing and the cover member. The inner surface of the cover member includes a partial region in which the bonding material is absent. The partial region includes a region in which the piezoelectric vibrating element is located and extends to one part of a periphery of the inner surface. The intervening member is located between the housing and a region of the partial region close to the one part of the periphery relative to the piezoelectric vibrating element and is less likely to interfere with a vibration of the cover member than the bonding material.
