Stereo Speaker Stand With Directional Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large stereo speakers face challenges in positioning due to weight, causing instability and potential noise from vibrations, as they often cannot be raised to direct sound effectively and may vibrate excessively, risking displacement and affecting sound quality.
Innovation Solution
A support stand with isolating and polarizing assemblies that allow more movement in one direction than another, combined with adjustable rods and a mechanism to tilt the shelf, enabling the speaker to absorb vibrations and air movement while maintaining stability and directing sound effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If speakers are raised off the floor to direct sound outwardly at appropriate height, then sound quality is enhanced, but speakers may vibrate excessively and migrate across the surface due to low frequency energy and air movement
Solution Approach 1:
The patent introduces an intermediary support structure between the speaker and the floor surface. This support includes vibration-absorbing elements and friction-reducing surfaces that mediate the interaction between the vibrating speaker and the stationary floor, allowing the speaker to be elevated for optimal sound projection while preventing excessive migration and instability
Solution Approach 2:
The support structure incorporates vibration-dampening materials and shock-absorbing elements positioned in advance to cushion the speaker against the effects of low frequency energy and air movement. This beforehand cushioning prevents the speaker from migrating across the surface while maintaining its elevated position for optimal sound quality
2Illumination intensity
If speakers are placed on stands or shelves to raise them off the floor, then sound direction is improved, but heavy speakers cannot be supported and may cause the support to vibrate and generate unwanted noise
Solution Approach 1:
The patent modifies the physical parameters of the support structure by using materials with specific friction coefficients and vibration-dampening properties. The support surface is designed with controlled friction characteristics that prevent speaker migration while the vibration-absorbing elements are selected to match the frequency range of speaker vibrations, changing the mechanical parameters to achieve both stability and reliable support for heavy speakers
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 stand effectively isolates and stabilizes the speaker, reducing unwanted noise and ensuring the speaker remains secure, allowing for directed sound emission by absorbing vibrations and air movement without transmitting them to the floor, thus enhancing sound quality and safety.
Implementation Method 1
This low frequency energy may generate considerable vibrations in the speaker and cause it to move forward and rearward across a surface
Implementation Method 2
move back and forth in response to vibrations in the speaker and air movement adjacent the same
Implementation Method 3
a plurality of isolating and polarizing assemblies that engage the support and allow movement of the speaker relative to the support in one direction more than in another direction

AI summary
A stand for a stereo speaker. The stand comprises a support and a plurality of isolating and polarizing assemblies that engage the support and allow movement of the speaker relative to the support in one direction more than in another direction and to isolate that movement relative to the floor surface upon which the support rests. Preferably, the stand also includes a shelf and a plurality of rods that engage the assemblies and connect the shelf to the support. A first assembly engages a first end of each rod with the shelf and a second assembly engages the second end of each rod with the support. The assemblies are configured to permit more movement of the rods in a first horizontal direction than in a second horizontal direction. Thus, the assemblies allow the shelf to move back and forth in the first horizontal direction in response to vibrations in the speaker and air movement adjacent the same. The stand also includes a mechanism for adjusting the inclination of the shelf relative to the support so as to allow sound emitted therefrom to be directed in a particular direction.
