Hanging Speaker System Cancellation Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speaker systems in enclosed areas often experience unwanted wave cancellation due to out-of-phase crossover frequency soundwaves when speakers are spaced apart, leading to suboptimal acoustics and aesthetic issues.
Innovation Solution
A hanging speaker system comprising a speaker assembly with a cylindrical housing, a hanging component, and both low-range and higher-range speakers, designed to minimize crossover frequency interference by optimizing soundwave projection and distribution through a unique port channel and baffle configuration, allowing for balanced sound coverage without visual obtrusiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If speakers are spaced apart in conventional systems, then coverage area is improved, but wave cancellation effects worsen due to out-of-phase crossover frequency soundwaves
Solution Approach 1:
The patent positions speakers vertically at different heights (ceiling, wall, floor mounting options) rather than only horizontally, creating three-dimensional sound distribution. This vertical dimensionality change allows speakers to be spaced apart while maintaining phase coherence through optimized acoustic paths and crossover frequency management between vertically stacked drivers.
Solution Approach 2:
The patent implements adjustable crossover frequencies and phase alignment parameters through electronic control circuits. By dynamically adjusting crossover points and phase relationships between low-range and high-range speakers, the system eliminates wave cancellation effects while maintaining wide coverage area through coordinated multi-speaker operation.
2Ease of operation
If speakers are positioned on floors or mounted to walls, then installation ease is improved, but aesthetic quality worsens due to visual obtrusiveness and displaced fixtures
Solution Approach 1:
The patent designs speaker assemblies with universal mounting capabilities that can be installed on ceilings, walls, or floors using the same basic hardware configuration. The integrated mounting bracket system provides multiple attachment options, allowing the same speaker unit to serve different installation scenarios while maintaining aesthetic discretion through concealed mounting mechanisms.
Solution Approach 2:
The patent offers speaker housings in various colors and finishes that can blend with ceiling or wall surfaces. The compact cylindrical design with available color options allows speakers to camouflaged against architectural surfaces, making them visually discreet while maintaining ease of installation through standardized mounting interfaces.
3Ease of manufacture
If speakers are positioned on floors or furniture, then setup simplicity is improved, but acoustic quality worsens due to suboptimal acoustics and displacement of other fixtures
Solution Approach 1:
The patent utilizes vertical suspension from ceilings to position speakers in three-dimensional space optimized for acoustic performance. This vertical dimensionality allows speakers to hang freely without contact with floors or furniture, eliminating unwanted vibrations and acoustic interference from surfaces while maintaining simple installation through overhead mounting only.
Solution Approach 2:
The patent introduces suspension cables or rigid rods as intermediary elements between the ceiling mounting point and the speaker assembly. These intermediaries provide acoustic isolation, preventing direct contact between speakers and structural surfaces that would cause unwanted vibrations, while still allowing simple overhead installation without complex mounting hardware.
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 effectively reduces crossover frequency cancellation, providing balanced sound coverage to most regions of the listening area while maintaining a discreet, aesthetically pleasing installation by suspending speakers from ceilings, thus enhancing both acoustic quality and ambient aesthetics.
Implementation Method 1
The upper chamber is acoustically shaped for projecting low frequency soundwaves generated by the low-range speaker down to the lower chamber
Implementation Method 2
The inner chamber encloses the higher range speaker therein and is acoustically shaped for projecting higher frequency soundwaves
Implementation Method 3
the lower end of the outer wall of the upper section near the lower port exit may be flared radially outward slightly so as to increase the cross section area of the lower port exit and thereby reduce port noise

AI summary
A speaker system broadly comprises a plurality of speaker assemblies each including a speaker housing, an input circuit, a low range speaker, and a higher-range speaker. The input circuit receives audio signals from a sound system or other controller and actively or passively sends the audio signals to the speakers. The low-range speaker is positioned in the upper section and the higher-range speaker is positioned in the lower section. Each speaker assembly is configured to be suspended from an elevated structure and spaced from the other speaker assemblies within a listening area with each speaker assembly generating low frequency soundwaves and higher-frequency soundwaves. This reduces or eliminates out-of-phase crossover frequency wave cancellation effects within the listening area. The speaker housings are compact while allowing the low-range speaker and higher-range speaker to effectively produce and project desired soundwaves from the suspended speaker housing into the listening area.
