Front-Emitting Display Audio Housing with Rotatable Speaker Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face issues with audio quality degradation and distortion due to audio emission towards the top or bottom, which is reflected from ceilings or floors, and cannot easily change posture to accommodate different indoor spaces and user preferences.
Innovation Solution
A display device design with a housing structure that includes a second frame extending from the first frame to direct audio emission towards the display area, incorporating a slit for direct audio transmission, and a posture detection sensor to adjust visual and audio output based on posture changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If audio is emitted towards the top or bottom of the display device, then the speaker module can be disposed in a compact arrangement, but audio quality degrades due to reflection from ceilings or floors
Solution Approach 1:
The second frame is designed to be rotatable relative to the first frame, allowing the audio emission direction to dynamically adjust. This enables the system to switch between emitting audio towards the top/bottom (compact arrangement) and towards the display area (high quality), resolving the contradiction between compactness and audio quality.
Solution Approach 2:
The patent changes the orientation parameter of the second frame relative to the first frame. By adjusting the rotation angle between 0-180 degrees, the system can optimize the audio emission direction to either face the display area for high quality or face upward/downward for compact installation, thus resolving the contradiction.
2Device complexity
If the display device is fixed in a specific posture, then the housing structure remains simple, but the device cannot adapt to different indoor spaces and user preferences
Solution Approach 1:
The second frame is made rotatable relative to the first frame through a rotation mechanism, enabling the housing to dynamically adjust its posture. This allows the display device to adapt to different installation scenarios (wall-mounted, ceiling-mounted, floor-standing) while maintaining a relatively simple integrated housing structure.
Solution Approach 2:
The rotatable housing structure enables the display device to serve multiple functions and adapt to various indoor spaces. The same housing can be configured for wall mounting, ceiling mounting, or floor standing by simply adjusting the rotation angle, eliminating the need for different housing designs for different applications.
3Object-affected harmful factors
If the second frame extends from the first frame to direct audio emission, then audio transmission quality improves, but the housing structure becomes more complex
Solution Approach 1:
The second frame is integrally formed with the first frame, merging the structural support function with the audio direction control function. This integrated design achieves effective audio directionality without requiring separate complex mechanisms, thus improving audio transmission quality while minimizing housing structure complexity.
Solution Approach 2:
The second frame serves dual functions: it provides structural support for the speaker module and simultaneously controls the direction of audio emission. By making the second frame rotatable, it also enables posture adjustment. This multi-functionality reduces the need for additional components, achieving effective audio direction with minimal added complexity.
4Adaptability or versatility
If a posture detection sensor is added to adjust visual and audio output, then adaptability to different postures improves, but device complexity increases
Solution Approach 1:
The posture detection sensor provides feedback about the current orientation of the display device to the processor. The processor then automatically adjusts the visual and audio output based on this feedback, enabling the system to adapt to different postures (portrait, landscape, wall-mounted, ceiling-mounted) without requiring manual configuration, thus improving adaptability with a relatively simple feedback control system.

AI summary
A display device includes a display panel; a housing comprising a first frame including a plate to support the display panel and a second frame formed to extend from one periphery of the first frame along a direction toward which a display area of the display panel faces; a speaker module including at least one speaker and disposed in the second frame; and a circuit board on the second frame and to be operatively connected to the display panel and the speaker. The second frame includes a slit on an outer surface of the second frame that faces the direction along which the second frame extends.
