Adjustable Two-Tier Amplifier Stand for Stage Space and Sound Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Professional musicians face issues with amplifier failure during performances, which disrupt events and limit stage space, and existing stands either clutter the stage or direct sound waves improperly, affecting both the musician and the audience.
Innovation Solution
An amplifier stand that supports two amplifiers, elevates them for enhanced sound dispersion, and allows for easy adjustment to fit various sizes and shapes, while being collapsible for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two amplifiers are brought to a performance to ensure backup capability, then reliability is improved, but the stage space is reduced and the performance space appears cluttered
Solution Approach 1:
The patent transitions from horizontal placement of amplifiers on the stage to vertical stacking arrangement. The stand structure allows one amplifier to be positioned directly above another, utilizing the vertical dimension to accommodate backup amplifier capability while minimizing the horizontal footprint on stage.
2Area of stationary object
If an amplifier is placed on the ground or stage, then space is saved, but the sound waves travel past the musician's legs and the musician cannot hear the feedback
Solution Approach 1:
The stand elevates the amplifier from ground level to an elevated position using vertical support members. This vertical elevation allows sound waves to propagate horizontally toward the musician's ears rather than traveling downward past the legs, resolving the feedback issue while maintaining space efficiency.
3Ease of operation
If an amplifier stand tilts the amplifier at forty-five degrees to direct sound at the musician's ears, then musician feedback is improved, but the sound waves do not travel directly toward the audience and the amplifier must be louder which may cause hearing loss
Solution Approach 1:
The stand positions the amplifier horizontally at an elevated height, creating an equipotential sound distribution field where sound waves propagate equally toward both the musician and the audience. This eliminates the need for tilted positioning and excessive volume compensation, preventing hearing loss while maintaining feedback quality.
4Ease of manufacture
If a fixed amplifier stand structure is used, then manufacturing is simpler, but the stand cannot accommodate amplifiers of various sizes and shapes
Solution Approach 1:
The stand incorporates adjustable components including telescoping support members with variable height settings and configurable base members. These dynamic elements allow the stand structure to adapt to different amplifier dimensions and shapes while maintaining structural integrity and functionality.

AI summary
An amplifier support stand includes two tiers of supports such that the stand is capable of supporting two amplifiers above the ground and on a level surface, which results in efficient use of stage space and enhanced sound quality from the amplifiers. The amplifier support stand includes two base members, two amplifier support members, and a frame interconnecting the base members and the support members. The base members support the stand on the ground and function as a first tier of supports for a first amplifier. The amplifier support members function as a second tier of supports for a second amplifier directly above the first amplifier. The frame enables relative movement between the amplifier support members and the base members to accommodate amplifiers of various sizes. The base members and support members are rotatable to minimize the stand's dimensions for compact storage. A corresponding method of use is also provided.
