Abstract: A glass sheet composite includes at least two sheets and a liquid layer held between the two sheets, and at least one of the two sheets being a glass sheet. In the glass sheet composite, the two sheets have been disposed so that an edge surface of one of the two sheets and an edge surface of the other sheet are not flush with each other to constitute a step portion having a stair-like shape in a cross-sectional view, and the glass sheet composite further comprising a seal material provided to the step portion to seal up at least the liquid layer.

Abstract: A glass sheet composite includes a first glass sheet, a second sheet disposed opposite the first glass sheet, and a liquid layer formed by sealing up a liquid between the first glass sheet and the second sheet, in which the glass sheet composite has a plurality of vibration areas that are independent of each other in a plan view. The glass sheet composite is a diaphragm including at least one vibrator disposed on one side or both sides of the glass sheet composite. The glass sheet composite enables independent vibration at each of the vibration areas, and enables not only stereophonic or multiphonic reproduction but also local reproduction to be performed along with images. Since the diaphragm includes a vibrator, this diaphragm is excellent in sound reproduction.

Abstract: The present invention provides a display device and a television device with which it is possible to reduce the thickness of the device profile while also realizing desirable acoustic characteristics. This display device includes: a first plate-shaped object; a display module including a display element and a second plate-shaped object that supports the display element, the display module being disposed so as to face the first plate-shaped object; a liquid layer formed by sealing up a liquid between the first plate-like object and the display module; and a vibrator provided to the first plate-shaped object and/or the display module. The loss coefficient of the display device at 25° C. is 1×10−2 or greater and a thickness ratio between the first plate-shaped object and the display module is from 1:10 to 10:1.

Abstract: A vibration device includes a plate-like glass vibrator and a plurality of exciters that are attached to the glass vibrator and configured to generate vibration according to an input electrical signal. An aspect ratio La/Lb of a length La of a longer side to a length Lb of a shorter side of a rectangle in which the glass vibrator is inscribed is 1.2 to 50. Provided that the number of the exciters is n and a minimum value of distance between the exciters is Smin, a relational value α (α=Smin−1)/La) is 0.2 to 0.8. In the case where the number n of exciters is 3 or larger, a value β(β=Sσ/Save) obtained by dividing a standard deviation Sσ of distances by an average Save of the distances between the exciters is 0 to 0.5.

Abstract: The glass sheet composite of the present invention includes at least two sheets, a liquid layer held between two adjacent sheets of the at least two sheets, and a seal material disposed between the two sheets so as to seal up the liquid layer, in which at least one of the two sheets is a glass sheet, the glass sheet composite including a light-shielding part disposed so as to overlay a boundary between the liquid layer and the seal material when the glass sheet composite is viewed in a plan view. Because of this, the boundary can be concealed, and this not only results in an improvement in designability and a wider choice of materials for the liquid layer and the seal material.
