Problems solved by technology

However, the sound velocity of these materials is low, so when excited at a high frequency, it is difficult for the vibration of the material to follow the frequency of the sound wave, and it is easy to generate split vibration

Abstract

The purpose of the present invention is to provide a glass plate construct that realizes desirable visibility when applied to a display, etc. This glass plate construct is provided with at least two plates, a liquid layer held between two adjacent plates among the at least two plates, and a sealing material provided in at least a portion of the periphery of the two plates so as to seal the liquidlayer, at least one of the two plates being a glass plate, and the photorefractive index difference between the liquid layer and the sealing material being 0.015 or less.

Description

technical field [0001] The present invention relates to a glass plate structure having good visibility and acoustic performance, and also to a vibrating plate and an opening member using the glass plate structure. Background technique [0002] Usually, a paper cone or resin is used as a diaphragm for a speaker or a microphone. Since these materials have a large loss coefficient and hardly generate vibration due to resonance, it is considered that the sound reproduction performance in the auditory range is good. However, they are all materials with low sound velocity values, so when excited at high frequencies, it is difficult for the vibration of the material to follow the frequency of the sound wave, and split vibrations are likely to occur. Therefore, it is difficult to generate the desired sound pressure especially in the high frequency region. [0003] In recent years, especially in high-resolution (high resolution) sound sources, etc., the reproduction band is require...
