Connected Display Sound Reception for Multi-Channel Stereo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with integrated sound reception units lack the capability to generate multi-channel stereo effects due to single-channel sound signal synthesis, limiting the audio-visual experience when multiple devices are assembled.
Innovation Solution
A display apparatus with multiple sound reception units on connected display devices and a sound reception processor that generates stereo signals by combining directional sound signals from each unit, creating multi-channel audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound reception units are placed on display devices, then sound reception capability is provided, but multi-channel stereo effect cannot be generated due to single-channel synthesis
Solution Approach 1:
The patent divides the sound reception system into multiple independent sound reception units distributed across multiple display devices. Each unit captures sound from different spatial positions and directions, enabling the system to collect multi-dimensional sound information that can be processed into multi-channel stereo signals, thereby resolving the limitation of single-channel synthesis.
Solution Approach 2:
The patent transitions from single-channel to multi-channel sound processing by adding spatial dimensionality. By placing sound reception units at different positions and orientations across multiple display devices, the system captures sound from multiple directions (left, right, front, back), creating directional sound signals with distinct spatial characteristics that enable stereo effect generation.
2Area of stationary object
If multiple display devices are arranged side by side, then widescreen display is achieved, but multi-channel stereo effect is still not provided
Solution Approach 1:
The patent merges the sound reception capabilities of multiple display devices into a unified multi-channel audio system. By connecting sound reception units from different display devices to a common processing system, the patent combines their individual directional sound signals into integrated stereo signals, allowing the multi-display assembly to provide multi-channel stereo effect while maintaining the widescreen display configuration.
3Device complexity
If sound reception units are placed at the same angle, then simple device structure is maintained, but directionality information is lost
Solution Approach 1:
The patent applies local quality by configuring sound reception units with different directional characteristics at different positions. Each sound reception unit is oriented to capture sound from its specific local direction, creating directional sound signals with unique spatial information. This local directional specialization across multiple units preserves comprehensive directionality information while maintaining relatively simple individual unit structures.

AI summary
A display apparatus includes a first display device having two first sound reception units, a second display device having two second sound reception units, and a sound reception processor. The second display device is connected to a side of the first display device. The sound reception processor is coupled to the first sound reception units and the second sound reception units. The sound reception processor turns on at least one of the first sound reception units to receive sound in a first normal direction of the first display device for generating a first directional sound signal, turns on at least one of the second sound reception units to receive sound in a second normal direction of the second display device for generating a second directional sound signal, and generates a stereo signal according to the first directional sound signal and the second directional sound signal.
