Display Device Panoramic Sound Using Top Side Middle Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current panoramic sound systems require a large number of speakers, which are space-intensive and heavy, making it difficult to achieve a panoramic sound experience in small spaces without expensive home theater systems.
Innovation Solution
A display device with a middle sound production circuit, two side sound production circuits, and a top sound production circuit, which performs space model parameter modification and determines audio source information based on video source information to produce sound in three dimensions, including the height direction, using virtual speaker technology and a microphone array to adjust sound production accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional panoramic sound systems use multiple speakers (5.1-channel + top speakers), then a 360-degree sound field surround experience is achieved, but the system becomes space-intensive and heavy
Solution Approach 1:
The patent combines multiple sound production circuits (middle, two sides, and top) into a single integrated display device, merging functions that traditionally required separate speakers into one unified system, thereby reducing overall system weight and space requirements
Solution Approach 2:
The patent adds a height dimension to the sound field by incorporating top sound production circuits that emit sound upward to reflect off the ceiling, creating a three-dimensional sound experience that encompasses vertical space, thereby achieving panoramic surround sound without requiring additional peripheral speakers
2Reliability
If traditional panoramic sound systems use multiple speakers and home theater systems, then a 360-degree sound field surround experience is achieved, but the system requires large installation space
Solution Approach 1:
The patent integrates middle, side, and top sound production circuits within a single display device structure, combining multiple acoustic functions into one compact unit that eliminates the need for separate speakers distributed throughout the room
Solution Approach 2:
By utilizing the vertical dimension through top sound production circuits that emit sound upward for ceiling reflection, the system achieves omnidirectional coverage without requiring lateral expansion of speaker placement, thereby maintaining a compact horizontal footprint
3Reliability
If traditional panoramic sound systems use multiple speakers, then a 360-degree sound field surround experience is achieved, but the system becomes expensive
Solution Approach 1:
The patent consolidates multiple sound production functions into integrated circuits within the display device, reducing the total component count and eliminating the need for expensive peripheral speakers and complex home theater system installations
Solution Approach 2:
The display device serves multiple functions simultaneously - it acts as both a visual display and an integrated panoramic sound system with middle, side, and top sound production capabilities, eliminating the need for separate audio equipment and reducing overall system cost
