Glass Plate Component Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass sheet composites face challenges in achieving excellent acoustic performance due to vibration transmission from the glass sheet diaphragm to the support member, leading to unwanted sound generation.
Innovation Solution
The glass sheet composite incorporates a support structure with fixing parts and vibration-permitting parts, where the diaphragm is attached to the support member through intermittent fixing parts and vibration-permitting parts that allow vibration while preventing its transmission to the support member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the glass sheet is supported on the support member through a mediation layer, then the glass sheet can be stably supported, but the vibration of the glass sheet is transmitted to the support member causing unwanted sound generation
Solution Approach 1:
The support structure is segmented into multiple independent support points rather than continuous support. The first support point supports the glass sheet at a location away from the exciter, while the second support point supports the glass sheet at a different location, allowing vibration isolation between the glass sheet and support member.
Solution Approach 2:
A damping material is introduced as an intermediary layer between the glass sheet and the support member. This damping material absorbs and dissipates vibration energy, preventing the transmission of unwanted vibrations from the glass sheet to the support member while maintaining support stability.
2Reliability
If all peripheral edge portions of the glass sheet are supported on the frame body, then the glass sheet is fully supported, but the support member vibrates and generates sound
Solution Approach 1:
The continuous support along all peripheral edges is segmented into discrete support points. The glass sheet is supported at specific locations (first support point away from exciter, second support point at different location) rather than continuously along the entire perimeter, reducing vibration transmission paths.
Solution Approach 2:
Different regions of the glass sheet edge are treated differently. The area around the exciter is left unsupported to allow free vibration, while other specific locations provide localized support. This local differentiation allows the glass sheet to vibrate freely in critical areas while maintaining overall support stability.

AI summary
The purpose of the present invention is to provide a glass plate component having satisfactory acoustic performance. The present invention relates to a glass plate component comprising: a vibrating plate made to vibrate by a vibrating element; and a support member that is attached along the edge of the vibrating plate and that supports the vibrating plate. The vibrating plate is provided with at least one glass plate and is supported by the support member via a fixing section for fixing the edge of the vibrating plate and the support member and via a vibration-permitting section permitting vibration of the vibrating plate.
