Servo-Adjusted Speaker Orientation for Spatial Audio Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Audio-visual devices and systems fail to provide depth and spatial perception of sound that matches the visual output, resulting in a two-dimensional audio experience despite enhancements through equalization and dynamic range compression.
Innovation Solution
The implementation of a stereophonic device and sound system that includes a servomechanism to adjust the angular direction of speakers based on visual presentations, combined with dynamic range compression and equalization to enhance audio signals, and the use of both front- and rear-facing speakers to create a three-dimensional audio experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If equalization and dynamic range compression are used to enhance audio signals, then audio quality is improved, but spatial perception and depth are not achieved
Solution Approach 1:
The patent transitions from traditional two-dimensional audio output (front-facing speakers only) to three-dimensional spatial audio by adding rear-facing speakers and implementing adjustable angular positioning. This dimensional change enables sound to be delivered from multiple directions, creating true spatial perception and depth that matches the visual presentation on the display device.
Solution Approach 2:
The system employs dynamically adjustable speaker angular positioning that can change in real-time based on the visual content being displayed. The speakers are not fixed in position but can be adjusted to coordinate with moving objects or spatial elements in the visual presentation, creating a dynamic audio-visual synchronization that enhances spatial perception.
2Device complexity
If traditional front-facing speakers are used, then device simplicity is maintained, but spatial perception and depth are limited
Solution Approach 1:
The patent adds rear-facing speakers to create a multi-dimensional audio output system. This configuration enables sound to be delivered from both front and rear directions, creating a three-dimensional audio space that provides true spatial perception and depth, directly addressing the limitation of traditional front-facing-only speaker systems.
3Device complexity
If speaker angular direction is fixed, then device complexity is reduced, but coordination with visual presentation is insufficient
Solution Approach 1:
The system implements dynamically adjustable speaker angular positioning that can change in real-time based on the visual content being displayed. The speakers are not fixed in position but can be adjusted to coordinate with moving objects or spatial elements in the visual presentation, creating a dynamic audio-visual synchronization that enhances spatial perception.
Solution Approach 2:
The system uses feedback from the visual presentation content to dynamically adjust speaker positioning. By monitoring the visual display and coordinating speaker angular direction based on the spatial location of objects or events in the visual content, the system achieves adaptive coordination between audio and visual elements.

AI summary
A stereophonic device includes a first speaker to output audio associated with the visual presentation. The output of the first speaker is directed in a direction opposite the visual output of a display device. The stereophonic device includes a servomechanism to adjust an angular direction of an output of a first speaker based on a visual presentation presented on a display device associated with the audio signal to coordinate the output of the first speaker with expected spatial sounds perceived in the visual presentation.
