Audiovisual Apparatus Sub-Speaker Inclination for Wide Viewing Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audiovisual apparatuses struggle to provide a realistic sensation due to limitations in sound localization and surround sound distribution, particularly in widening the viewing region for immersive audio experiences.
Innovation Solution
The audiovisual apparatus includes a display section and main speakers, with sub-speakers having sound output surfaces inclined outward relative to the main speakers, enhancing sound distribution and providing a wider viewing region for realistic sensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the sound output surfaces of sub-speakers are arranged to be inclined toward outside of the display section, then the viewing region providing realistic sensation is widened, but the device complexity increases
Solution Approach 1:
The patent applies local quality by differentiating the orientation of sub-speakers from main speakers. Specifically, sub-speakers are inclined outward at angles between 10-30 degrees relative to the display section, while main speakers remain parallel to the display section. This localized differentiation optimizes sound distribution in the surround region without complicating the overall system design.
Solution Approach 2:
The patent implements asymmetry in the speaker arrangement by inclining sub-speakers outward while keeping main speakers parallel to the display section. This asymmetric configuration creates optimized sound coverage patterns that widen the viewing region for realistic sensation, transforming a symmetric arrangement into an asymmetric one that better serves the surround sound function.
2Reliability
If multiple speakers are provided for surround sound, then realistic sensation is improved, but the device complexity increases
Solution Approach 1:
The patent segments the speaker system into two functional groups: main speakers positioned parallel to the display section for primary audio output, and sub-speakers inclined outward for surround sound distribution. This segmentation allows each group to perform its specialized function effectively, improving realistic sensation while managing complexity through functional differentiation rather than simply adding more speakers.
Solution Approach 2:
The patent applies local quality by assigning different orientations and positions to different speaker groups based on their functional requirements. Main speakers face forward for dialogue and primary audio, while sub-speakers are angled outward for ambient and surround effects. This localized optimization achieves enhanced realistic sensation with a manageable number of speakers.

AI summary
An audiovisual apparatus includes: a display section configured to display a picture; and one or a plurality of main speakers and a plurality of sub-speakers each having a sound output surface generating sound corresponding to the picture. The sound output surfaces of one or more of the plurality of sub-speakers are arranged to be inclined toward outside of the display section as compared with the sound output surfaces of the main speakers.
