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.

Abstract: A glass sheet composite includes: two or more sheets; and an intermediate layer between at least a pair of the sheets. At least one of the pair of sheets is a glass sheet. The intermediate layer satisfies all of the following properties: (1) the intermediate layer has a thickness of 20 μm or less, (2) a compressive shear storage modulus at a temperature of 25° C. is 1.0×104 Pa or less, and (3) at the temperature of 25° C. and 1 Hz, the compressive shear storage modulus is higher than a compressive shear loss modulus. The glass sheet composite has a loss coefficient at 25° C. of 0.01 or more, and a sheet-thickness-direction longitudinal wave acoustic velocity of 4.0×103 m/s or more,

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 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: 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.
