Speaker Stand Bushings for Directional Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large stereo speakers face challenges in positioning due to weight, causing vibrations and potential instability when elevated, leading to compromised sound quality and risk of movement across surfaces, with existing support systems failing to effectively isolate and adjust for these issues.
Innovation Solution
A speaker stand with resilient bushings and adjustable rods that allow for controlled movement in one direction while isolating vibrations from the surface, using a support frame and rods to maintain stability and direct sound emission upward or downward.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If speakers are raised off the floor to direct sound at appropriate height, then sound quality is enhanced, but speakers become unstable and may migrate across the surface due to vibrations and air movement
Solution Approach 1:
The stand allows the speaker to move dynamically with vibrations rather than resisting movement, accommodating the natural motion caused by bass frequencies and air movement while maintaining stability through controlled motion paths
Solution Approach 2:
The resilient bushings act as intermediaries between the speaker and the support surface, absorbing and isolating vibrations to prevent direct transmission to the surface while supporting the speaker at the required height
2Illumination intensity
If speakers are supported a distance above the surface, then sound distribution is improved, but the support structure vibrates with the speaker generating unwanted noise
Solution Approach 1:
Resilient bushings serve as intermediary elements between the speaker cabinet and the support surface, absorbing vibrations and preventing their transmission to the support structure, thereby eliminating unwanted noise generation
Solution Approach 2:
The design converts the harmful vibrations into beneficial controlled movements by allowing the speaker to move within defined parameters through resilient bushings, transforming potential noise into acceptable operational motion
3Ease of operation
If heavy speakers are placed on stands, then appropriate positioning is achieved, but the stands may be damaged by the weight and vibration
Solution Approach 1:
Protective members are attached to the rod ends before the stand is placed under the speaker, providing pre-positioned cushioning that distributes the speaker's weight and absorbs vibration impacts, preventing damage to both the stand and support surface
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a stable base for large speakers, reducing unwanted noise and movement, allowing for precise sound direction and enhancing sound quality by isolating vibrations and adjusting to air movement, thus ensuring the speaker remains secure and focused on the intended sound path.

AI summary
A stand for supporting an article a spaced distance above a support surface and for damping vibration therebetween. The stand includes a support frame having resilient bushings engaged therewith. Each bushing defines a bore into which a first end of one of a plurality of rods is received. The rods extend downwardly from the bushings and abut the support surface. The bores are configured to permit the rods to move more in one horizontal direction than in another.
