Omnidirectional Sound System with Tilted Vertical Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surround sound systems are complex to set up and have a limited area where sound can be received from all sound emitting elements simultaneously, restricting the immersive audio experience for listeners.
Innovation Solution
A compact sound system with sound emitting elements mounted evenly around the periphery of a body, tilted up to 15 degrees, and an electronic circuit providing different drive signals to each element for a multichannel configuration, allowing sound to be emitted from a single location in multiple directions, creating a more ambient experience through environmental reflections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound emitting elements are placed at several locations to create surround effect, then sound can be received from multiple directions, but the area receiving sound from all elements at once becomes relatively narrow
Solution Approach 1:
The patent combines multiple sound emitting elements into a single integrated unit that emits sound from one location in multiple directions simultaneously, merging the functionality of multiple separate speakers into one compact device that provides omnidirectional sound coverage
2Adaptability or versatility
If sound emitting elements are placed at several locations to create surround effect, then surround sound is achieved, but the system becomes complex to set up
Solution Approach 1:
The patent integrates multiple sound emitting elements into a single unified device, eliminating the need for separate speaker placements and complex setup procedures while maintaining surround sound capability through omnidirectional emission from one location
3Adaptability or versatility
If sound emitting elements are mounted on vertical panels tilted away from vertical axis, then sound distribution is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies that vertical panels can be tilted at angles up to 15 degrees from the vertical axis, providing flexibility in sound distribution while maintaining reasonable manufacturing precision requirements through a defined angular parameter range
