Abstract: A carrier substrate to be used, when manufacturing a member for an electronic device on a surface of a substrate, by being bonded to the substrate, includes at least a first glass substrate. The first glass substrate has a compaction described below of 80 ppm or less. Compaction is a shrinkage in a case of subjecting the first glass substrate to a temperature raising from a room temperature at 100° C./hour and to a heat treatment at 600° C. for 80 minutes, and then to a cooling to the room temperature at 100° C./hour.

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.
