Rotatable Display Audio Channel Control for Stable Stereo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotatable display devices face challenges in maintaining an optimal audio setting when the display is rotated, as the speaker's orientation changes, leading to unwanted sound direction and a lack of suitable sound field or stereo effect.
Innovation Solution
A display device equipped with multiple speakers positioned in different regions relative to the rotating shaft, controlled by a processor that adjusts audio channel output based on the display's rotation, ensuring that audio signals are correctly routed and mixed to maintain an optimal sound field even during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the speaker is rotated together with the display, then the display device can provide optimized viewing experience for image contents with different aspect ratios, but the speaker outputs sound in an unwanted direction and cannot provide suitable sound field or stereo effect
Solution Approach 1:
The display device is divided into two independent parts: the display panel that can rotate, and the speaker system that remains fixed. This segmentation allows the display to adapt to different aspect ratios while the speaker maintains its optimal sound projection direction, resolving the contradiction between viewing optimization and sound quality.
Solution Approach 2:
The speaker is extracted from the rotating assembly and positioned separately from the display panel. By taking the speaker out of the rotating mechanism, the system can rotate the display for different viewing orientations while keeping the speaker in a fixed position to provide consistent sound field and stereo effect.
2Reliability
If the speaker is separated from the rotating display, then the sound direction and sound field are maintained, but the device complexity increases due to additional components and control mechanisms
Solution Approach 1:
The base unit housing both the speaker and the rotating mechanism is merged into a single integrated structure. This combining approach maintains sound stability by keeping the speaker fixed while integrating the rotation function, thereby reducing overall device complexity compared to having separate independent systems.
Solution Approach 2:
The base unit is designed with multi-functionality, serving both as the speaker housing and as the rotation mechanism support. This universal design allows a single component to fulfill multiple functions, reducing the total number of parts and simplifying the overall device structure while maintaining reliable sound output.
