Television Loudspeaker Arrangement with Movable Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional television sets often prioritize picture quality over sound quality, resulting in inadequate audio experience, particularly for formats like concerts, video games, and computer animations.
Innovation Solution
A television arrangement featuring a carrier with a screen unit and an active bass loudspeaker unit, along with at least two additional loudspeaker units that can be moved laterally to enhance stereo listening, powered by an amplifier unit, and optionally including a subwoofer for improved sound distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional TV sets prioritize picture quality, then display performance is improved, but sound quality deteriorates
Solution Approach 1:
The audio system is segmented into multiple independent loudspeaker units (first loudspeaker unit with bass elements, second loudspeaker unit with mid-range and high-frequency elements) that can be separately optimized and positioned. This segmentation allows each unit to handle specific frequency ranges, improving overall sound quality without compromising picture quality.
Solution Approach 2:
The patent merges the audio system with the television carrier structure, integrating multiple loudspeaker units directly onto the carrier. This combination creates a unified system where audio and video components work together, providing improved sound quality while maintaining a compact integrated design.
2Area of stationary object
If loudspeakers are positioned close together on the carrier, then device compactness is improved, but stereo hearing sensation deteriorates
Solution Approach 1:
The second loudspeaker unit is designed with movable mounting on the carrier, allowing its position to be adjusted dynamically. This enables the system to adapt the speaker spacing according to the viewer's distance and listening requirements, optimizing stereo sensation while maintaining compactness when needed.
Solution Approach 2:
The patent changes the positional parameter of the loudspeaker units, specifically allowing the second loudspeaker unit to be positioned at different distances from the screen depending on the viewing distance. This parameter adjustment optimizes the stereo effect for different usage scenarios without requiring a completely different device design.
3Reliability
If bass loudspeaker unit is placed at the rear, then sound quality is improved, but device stability deteriorates due to weight distribution
Solution Approach 1:
The carrier structure incorporates counterbalancing design elements that compensate for the rearward placement of the heavy bass loudspeaker unit. By strategically positioning other components or using structural counterweights, the system maintains proper center of gravity and stability despite the asymmetric weight distribution required for optimal sound quality.
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 provides a significant enhancement in sound quality by allowing for adjustable loudspeaker placement and power distribution, improving the overall audio experience and stability of the television arrangement.
Implementation Method 1
an active bass loudspeaker unit (6), such that the bass loudspeaker unit has an amplifier unit (62)
