Directional Sound Output Module for Multi-Source Display Audio Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large screen display devices showing multiple film sources, ensuring that viewers effectively listen to the corresponding sound for the picture they watch without interference from other film sources is a technical challenge.
Innovation Solution
An audio and video playing system that includes a directional sound output module and a tracking element to monitor the viewer's position and display area, allowing the processor to output sound information directly to the viewer's target visual area, using directional sound output modules such as ultrasonic directional sounders or phased loudspeaker arrays to ensure synchronized audio-visual experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple film sources are displayed in partitions on a large screen, then the display device can serve multiple viewing needs simultaneously, but sound interference occurs between different film sources making it difficult for viewers to listen to the corresponding sound
Solution Approach 1:
The display screen is divided into multiple independent display areas, each capable of displaying different film sources. Correspondingly, the sound output system is segmented into multiple directional sound output modules, with each module serving a specific display area. This segmentation allows independent audio playback for each film source without interference.
Solution Approach 2:
Each display area is assigned a dedicated directional sound output module that provides localized sound delivery. The sound output is customized for each region, ensuring that viewers in each display area receive the corresponding sound for the film source being displayed in their specific area.
2Ease of operation
If traditional omnidirectional sound output is used, then the sound can be heard by viewers in all directions, but the viewer cannot effectively listen to the sound of the specific picture they are watching
Solution Approach 1:
The system employs dynamic tracking to monitor the viewer's position and the displayed film source in real-time. The directional sound output module adjusts its sound delivery direction dynamically to match the viewer's viewing position and the corresponding display area, ensuring continuous audio-visual synchronization.
Solution Approach 2:
The tracking element provides feedback on the viewer's position and the active display area to the processor. Based on this feedback, the processor controls the directional sound output module to direct sound signals toward the viewer's location, maintaining accurate audio-visual correspondence.
3Reliability
If directional sound output modules are added to each display area, then sound interference is eliminated and audio-visual synchronization is improved, but the device complexity increases
Solution Approach 1:
The directional sound output modules are integrated with the display system to serve multiple functions: providing localized sound delivery, enabling multi-film source playback, and maintaining audio-visual synchronization. This multi-functionality reduces the need for separate independent sound systems for each display area.
Solution Approach 2:
The sound output functionality is merged with the display system architecture. The directional sound output modules are positioned corresponding to each display area and controlled by the same processor that manages the display, combining audio and video control into a unified system.
