Bar-Shaped Core-Rubber Vibration Isolator for Speaker Box Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration isolators for speaker boxes in electronic apparatuses are unstable and negatively impact the volume of the speaker box, making it difficult to securely support the box within a chassis with limited space.
Innovation Solution
A vibration isolator with a bar-shaped main body and plate-shaped attachment pieces, made of a core and rubber material, is used to support the speaker box, allowing for stable attachment and minimal volume reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dome-shaped rubber vibration isolator is attached to the speaker box, then the speaker box can be supported, but the volume of the speaker box is significantly reduced and the support stability is insufficient
Solution Approach 1:
The vibration isolator is divided into two functional parts: a bar-shaped main body for support and vibration isolation, and a separate plate-shaped attachment piece for secure mounting. This segmentation allows the main body to minimize volume impact while the attachment piece ensures stable support through screw fixation.
Solution Approach 2:
The attachment piece extends in a direction perpendicular to the main body, creating a three-dimensional structure that protrudes from the speaker box surface. This dimensional extension enables secure attachment without occupying significant internal volume of the speaker box.
2Volume of moving object
If the speaker box volume is increased to send sound to a wide space, then the sound coverage is improved, but the chassis space becomes insufficient for stable support
Solution Approach 1:
By separating the support function into a dedicated attachment piece with screw holes, the system achieves stable support in limited chassis space without compromising the speaker box volume needed for wide sound coverage.
Solution Approach 2:
The vibration isolator acts as an intermediary component between the speaker box and the chassis, providing stable support through its attachment piece while allowing the speaker box to maintain its required volume for effective sound propagation.
3Volume of stationary object
If a compact vibration isolator is used to save space, then the chassis space is optimized, but the support stability and vibration isolation performance are reduced
Solution Approach 1:
The bar-shaped main body provides efficient vibration isolation in a compact form, while the separate plate-shaped attachment piece ensures stable mounting. This segmentation allows space optimization without sacrificing vibration isolation performance.
Solution Approach 2:
The vibration isolator combines a core structure with rubber material covering, creating a composite component that achieves effective vibration isolation in a compact size, optimizing both space utilization and performance.
