Tiled Screen Speaker Allocation for Interference-Free Stereo Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spliced screens face issues with speaker resource waste and interference due to external audio device connections, leading to poor audio play effects and user experience.
Innovation Solution
A method for allocating spliced screen audio that constructs a speaker system using speakers from each screen, allocating channel types to form a stereophonic play mode, and managing audio and video data distribution to ensure interference-free and symmetrical audio playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If speakers of each screen are directly used to play audio, then speaker resources are utilized, but speakers of different screens cause interference during playing, resulting in poor play effect and poor user experience
Solution Approach 1:
The patent segments the spliced screen into multiple independent screen regions, each with its own speaker system. The host device allocates different audio channels to different screen segments based on their spatial positions, allowing each speaker to play only its designated channel rather than all audio simultaneously, thus avoiding interference while utilizing speaker resources.
Solution Approach 2:
The patent applies local quality by assigning different audio channel characteristics to different spatial locations of screens. Each screen segment receives audio processing tailored to its position (e.g., left screen gets left channel, right screen gets right channel), creating a coherent stereophonic field while preventing interference between adjacent speakers.
2Reliability
If a host is externally connected to an audio device such as a sound box in a wired manner, then audio consistency is ensured, but speaker resources of the screen are wasted
Solution Approach 1:
The patent enables screens to serve themselves by equipping each screen with built-in speaker devices that can independently play audio. The host device coordinates these self-service speakers through channel allocation, eliminating the need for external audio devices while fully utilizing the screens' own speaker resources.
Solution Approach 2:
The patent makes the screen system multi-functional by combining display and audio playback capabilities in a single integrated system. The screens can simultaneously function as display devices and audio output devices, eliminating the need for separate external audio equipment while maintaining audio consistency through centralized host control.
3Area of stationary object
If multiple screens are spliced to form a large display, then visual effect is improved, but audio allocation becomes complex and interference occurs
Solution Approach 1:
The patent segments both the visual display and audio output across multiple screens. Each screen is treated as an independent segment with its own speaker system, and the host device manages audio allocation by dividing the audio signal into spatial segments corresponding to each screen's position, simplifying the overall audio management complexity.
Solution Approach 2:
The patent extends audio allocation into the spatial dimension by mapping screen positions to audio channels. Instead of treating audio as a single unified signal, the system distributes audio across multiple spatial dimensions (left, center, right channels corresponding to different screen positions), transforming a complex single-channel problem into manageable multi-dimensional spatial audio allocation.

AI summary
This application provides a method for allocating spliced screen audio and a related device. A host controls a first combined screen, where the first combined screen includes at least two screens that are spliced. A first speaker system is constructed based on video source information of the at least two screens. The first speaker system includes a speaker of a first screen and a speaker of a second screen. In addition, corresponding channel types are allocated to the speakers included in the first speaker system based on screen parameters of the at least two screens. The channel types include a left channel, a center channel, and a right channel. In this way, the first speaker system may be constructed by using the speaker on each screen in the first combined screen, and a stereophonic play mode is formed by adding the center channel, so that the first combined screen can play audio data in a stereophonic manner, thereby improving a play effect.
