摘要： A glass plate construct provided with a first glass plate, a second plate disposed facing the first glass plate, and a liquid layer formed by sealing a liquid between the first glass plate and the second plate, the glass plate construct having a plurality of vibration areas that are independent from each other in a plan view. The glass plate construct is a diaphragm including at least one vibrator installed on one side or both sides of the glass plate construct. Independent vibration in each of the vibration areas is made possible, thus enabling stereophonic or multidimensional reproduction, as well as enabling local reproduction matched to a video. Furthermore, because the present invention is a diaphragm that includes a vibrator, sound reproduction is exceptional.

摘要： An optical member includes a transparent substrate containing at least one substance selected from glass, a glass ceramic, silicon, and sapphire, and having an infrared high-transmittance region in which an optical transmittance is 78% or more in a wavelength band of 700 nm to 1800 nm; and an optical interference film disposed on a main surface of the transparent substrate corresponding to the infrared high-transmittance region, wherein a transmittance of light, of the optical member, of at least one wavelength λ s in the wavelength band of 700 nm to 1800 nm in a region of the optical member corresponding to the infrared high-transmittance region of the transparent substrate has a minimum value of 86.5% or more and has a difference between the minimum value and a maximum value of 9% or less in a range where an incidence angle is from 0 degrees to 60 degrees.
