Display Speaker Sound Distribution via Segmented Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flat and lightweight display apparatuses, such as wall-hung TVs, face challenges in achieving expansive and clear sound quality due to speakers emitting sound primarily in downward and horizontal directions, requiring innovative sound distribution methods to enhance audio output.
Innovation Solution
The display apparatus incorporates an enclosure with a speaker positioned to emit sound in opposite and lateral directions through specifically designed opening areas, where the first opening area directs sound with greater volume and the second opening area directs sound at a lesser intensity, allowing for balanced sound distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker emits sound in downward and horizontal directions only, then the speaker structure is simple, but the sound quality is not expansive and clear
Solution Approach 1:
The opening area is divided into a first opening area and a second opening area, which are spatially segmented to emit sound in different directions. The first opening area emits sound in a direction opposite to the display portion, while the second opening area emits sound in a lateral direction, creating distinct sound paths that enhance overall sound quality without requiring complex speaker components
Solution Approach 2:
The sound emission is extended from a single-direction or two-directional setup to a three-dimensional sound distribution pattern. By adding the second opening area that emits sound in a lateral direction perpendicular to the first opening area's emission direction, the patent creates expansive spatial sound coverage that improves sound quality without increasing speaker complexity
2Reliability
If the speaker output is increased to achieve expansive sound quality, then the sound quality improves, but the weight and size of the display apparatus increase
Solution Approach 1:
The total opening area is segmented into two distinct opening areas with different functions. The first opening area handles sound emission in the opposite direction to the display portion, while the second opening area handles lateral sound emission. This segmentation allows efficient utilization of the existing speaker output to create expansive sound quality without requiring higher power speakers that would increase weight
Solution Approach 2:
The patent achieves expansive sound quality by distributing sound in multiple spatial dimensions rather than increasing speaker power. The lateral opening area adds a horizontal dimension to sound emission, creating immersive sound experience with the existing speaker output, thereby avoiding the need for larger, heavier high-power speakers
3Reliability
If the speaker output is increased to achieve expansive sound quality, then the sound quality improves, but the size of the display apparatus increases
Solution Approach 1:
The opening area is divided into two functional zones that work together to maximize sound quality from a compact speaker. The first opening area and second opening area are positioned to create complementary sound paths, allowing the small speaker to produce expansive sound quality through strategic spatial arrangement rather than through increased speaker size or power
Solution Approach 2:
The patent achieves expansive sound quality by utilizing three-dimensional space for sound emission rather than relying on high-power speakers that would require more internal volume. The lateral opening area introduces a horizontal sound path that complements the backward emission, creating immersive sound in a compact form factor

AI summary
According to one embodiment, a display apparatus includes an enclosure having a display portion and an internal space, and a speaker accommodated in the internal space and having a sound emitting surface directed in an opposite direction of the display portion. The enclosure includes a first opening area configured to emit sound of the speaker in the opposite direction of the display portion, and a second opening area configured to emit the sound of the speaker in a lateral direction to the display portion. A volume of the sound emitted from the first opening area is greater than a volume of the sound emitted from the second opening area.
