Problems solved by technology

However, in general, the loss factor of these materials is as small as about 1 / 10 to about 1 / 100 compared with paper, so it is easy to leave unexpected reverberation sound
In addition, when excitation is performed at the natural frequency of the component, a resonance mode occurs, and a significant deterioration of the tone color may occur due to this

Embodiment 1

[0178] A glass plate A of 110 mm x 110 mm x 0.5 mm was prepared as the second plate, and the second plate was a substrate one, on which a glass plate with a viscosity coefficient of 3000 mPa·s was coated using a dispenser (manufactured by Musashi Engineering; SHOTMASTER 400DS-s). Silicone oil (manufactured by Shin-Etsu Chemical Co., Ltd.; KF-96) was used as the liquid layer. Furthermore, a glass plate B of 100 mm x 100 mm x 0.5 mm was attached to the center of the glass plate A as the first plate. Thereby, the glass laminated body arrange|positioned so that the position of all the end surfaces of the said 2 glass plates may not correspond was obtained. Next, apply UV curable resin (manufactured by Kyoritsu Chemical; XVL-14) on the level difference between glass plate A and glass plate B, and let it cure, and then make glass plate A a size of 103mm x 103mm x 0.5mm The unbonded part was cut in the same way, and the glass plate structure with the height difference sealing was ob...

Embodiment 2

[0182] A glass plate structure was obtained in the same manner as in Example 1 except that the glass plate A was changed to an acrylic resin substrate of 110 mm×110 mm×0.5 mm.

Embodiment 3

[0184] A glass plate A of 100mm×100mm×0.5mm was prepared, and the viscosity coefficient was uniformly applied on it with a dispenser (manufactured by Musashi Engineering Co., Ltd.; SHOTMASTER 400DS-s) with a gap of 5mm in width from the end. 3000 mPa·s silicone oil (manufactured by Shin-Etsu Chemical Co., Ltd.; KF-96) was used as the liquid layer. Furthermore, a UV curable resin (manufactured by Kyoritsu Chemical; XVL-14) was coated on the end of the glass plate A with a line width of about 2 mm. Next, a glass plate B of 100 mm x 100 mm x 0.5 mm was pasted as the first plate in a state deviated from the central part of the glass plate A by 1 mm in the up, down, and left and right directions, and the first plate was the substrate 2, so that the liquid thickness was Bonding was performed under reduced pressure with a thickness of 3 μm. Thereby, the glass laminated body arrange|positioned so that the position of all the end surfaces of the said 2 glass plates may not correspond ...

Abstract

A glass plate structure comprising at least two plates and a liquid layer held between the two plates, wherein at least one of the two plates is a glass plate. In the glass plate structure, the end faces of the two plates are shifted to form a step-like height difference in cross-sectional view, and there is also a seal provided to seal at least the liquid layer in the height difference. Material.

Description

technical field [0001] The present invention relates to a glass plate structure having good acoustic performance, and also to a vibrating plate and an opening member using the glass plate structure. Background technique [0002] Generally, drum paper (corn paper) or resin is used as a diaphragm for a speaker or a microphone. These materials have a large loss coefficient and are less likely to generate resonant vibrations, so the reproduction performance of sound in the audible range is good. [0003] However, since the sound velocity values ​​in these materials are all low, it is difficult for the vibration of the material to follow the frequency of the sound wave when excited at a high frequency, and it is easy to generate split vibration. Therefore, it is difficult to obtain a desired sound pressure especially in the high frequency range. [0004] In recent years, especially in the case of high-resolution sound sources, etc., the frequency band required for playback is a...
