Cantilever Spring Bracket for Friction-Free Sound Transducer Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brackets for mounting sound transducers in walls or ceilings create friction due to direct contact, limiting the lower frequency response of the audio system by damping vibrations.
Innovation Solution
A bracket design that attaches only to the foot of the sound transducer, using a base, spring element, and plate to mount to architectural frame members, allowing the body to move freely and avoiding contact with other objects, thereby eliminating friction and enhancing frequency response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam layers are used to surround and hold the transducer body, then the transducer is securely mounted, but friction is created that dampens vibrations and limits lower frequency response
Solution Approach 1:
The foam material is completely removed from the mounting system. Instead of using foam to hold the transducer, the invention uses a bracket with a spring element that contacts only the foot of the transducer, extracting the harmful foam component while maintaining secure mounting through alternative mechanical means.
Solution Approach 2:
A metal bracket with spring element is introduced as an intermediary between the mounting surface and the transducer. This intermediary provides secure mechanical support through the spring element while the plate component guides and constrains the body's motion without creating friction through foam contact.
2Stability of the object's composition
If the transducer body is constrained by foam, then mounting stability is achieved, but the lower frequency response is limited due to dampening
Solution Approach 1:
The mounting system is segmented into distinct functional zones: the spring element handles vertical support and stabilization, while the plate handles lateral guidance. This segmentation allows each component to perform its specific function without interfering with the transducer's vibrational performance, preserving frequency response quality.
Solution Approach 2:
The spring element provides dynamic support that adapts to the transducer's operational movements. The spring can compress and extend to accommodate the body's oscillation along the shaft axis, maintaining stability during static conditions while allowing necessary motion during operation without dampening.
3Reliability
If foam surrounds the transducer body, then the transducer is held firmly, but friction prevents optimal vibration and sound production
Solution Approach 1:
The foam material that causes friction is completely removed from the system. The invention replaces foam-based retention with a metal bracket and spring element mechanism that secures the transducer foot while allowing the body to move freely along the shaft axis without frictional contact.
Solution Approach 2:
The plate acts as an intermediary that guides the body's motion without creating friction. It provides lateral constraint and alignment while allowing smooth movement along the shaft axis, eliminating the frictional harmful effects associated with foam contact.
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 enables optimal performance and frequency response by maintaining the sound transducer firmly against the soundboard without damping, ensuring effective sound transmission and balancing the load of the transducer.
Implementation Method 1
The spring element is attached to the base. The plate is attached to the spring element... The spring element exerts a pressure against the soundboard of between 4 lbs and 20 lbs
Implementation Method 2
The cantilever spring structure comprises first and second flaps attached to the base to provide flexibility for the spring element... The cantilever spring structure exerts a pressure against the soundboard of between 4 lbs and 20 lbs
Implementation Method 3
direct contact between the transducer and the foam creates friction and dampens the vibrations of the transducer
