Two-Axis Rotatable Speaker Mounts for Audio Dead-Zone Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound systems struggle with poor speaker placement, leading to inconsistent sound quality and dead zones, especially in environments lacking professional audio engineering, with surround sound systems causing interference and spatial audio systems limiting sound delivery to specific areas.
Innovation Solution
The use of rotatable speakers with variable sound control, mounted on adjustable bases and controlled by a DMX controller, ensuring minimal overlap and maximum coverage through dynamic speaker positioning and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple speakers are placed at predetermined points throughout a room to create surround sound, then sound coverage is improved, but speaker interference and dead zones occur
Solution Approach 1:
The patent applies the dynamics principle by enabling speakers to rotate and change their orientation dynamically. Each speaker housing can rotate about a vertical axis and tilt, allowing the sound projection direction to adapt in real-time. This dynamic positioning eliminates dead zones and interference patterns by continuously optimizing speaker orientation relative to listener positions, transforming static speaker arrays into adaptive sound distribution systems.
Solution Approach 2:
The patent implements another dimension by adding rotational and tilting degrees of freedom to the speaker system. Instead of fixed three-dimensional space coverage, the speakers operate in a four-dimensional space-time domain by continuously adjusting their orientation. This dimensional expansion allows sound to be distributed more uniformly throughout the room by projecting from multiple angular perspectives, eliminating the interference and dead zones characteristic of static surround sound systems.
2Measurement precision
If spatial audio systems target specific three-dimensional areas for sound delivery, then sound precision is improved, but sound coverage is limited to targeted areas
Solution Approach 1:
The patent applies universality by designing a speaker system that can perform multiple functions: precise targeted sound delivery and broad omnidirectional coverage. The same rotatable speaker housing can focus sound in a specific direction for precision audio or rotate to provide widespread coverage. This multi-functionality allows the system to adapt between creating precise sound images for immersive experiences and providing uniform sound distribution across entire spaces, eliminating the trade-off between precision and coverage.
3Reliability
If professional audio engineers are hired to design proper speaker layouts, then sound quality is improved, but system complexity and cost increase
Solution Approach 1:
The patent implements self-service by equipping each speaker with autonomous control capabilities through integrated processors and sensors. Each speaker housing independently determines its optimal orientation and sound projection parameters based on environmental feedback and desired audio objectives. This self-service functionality eliminates the need for external audio engineers to manually configure complex speaker layouts, as the system automatically optimizes itself, maintaining high sound quality while reducing design and operational complexity.

AI summary
The present invention disclosed is a system that improves the layout and sound delivery of speaker systems. The system is made up of one or more speakers that are mounted onto a rotatable bracket and brace that allows for the speaker to rotate about the x and y axes. This design allows users to tailor their speaker setup to meet the needs of the room where the system will be installed so to minimize overlap between the sounds produced by each speaker and to drastically reduce the dead zone areas. The result is that the listeners in the room will perceive sound that is much higher in quality then conventional systems that are currently available.
