Loudspeaker Structure for Flat Display Using Integrated Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flat display products with built-in loudspeaker systems face a trade-off between cost and audio performance, as high-end products with speaker boxes are expensive, while those without speaker boxes have poor audio quality, and there is a need to develop a cost-effective solution that improves audio performance.
Innovation Solution
A loudspeaker structure for flat displays is created by integrating the front frame and rear case to form a shield structure, which, along with a speaker driver, constructs a speaker box, reducing manufacturing costs and enhancing audio performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speaker boxes are equipped in display products, then audio performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the speaker box structure with the existing front frame and rear case of the display device. The front frame's inner surface is extended to form a first trench, and the rear case's inner surface is extended to form a second trench, integrating the speaker box into the display's existing structural components rather than adding a separate assembly
Solution Approach 2:
The front frame and rear case serve dual functions: they provide the structural framework for the display device and simultaneously form the speaker box enclosure. This multi-functionality eliminates the need for dedicated speaker box components, reducing manufacturing cost while maintaining audio performance
2Ease of manufacture
If speaker boxes are not equipped in display products, then manufacturing cost is reduced, but audio performance deteriorates
Solution Approach 1:
The patent combines the speaker box formation process with the existing manufacturing processes for the front frame and rear case. The trenches are formed by extending the inner surfaces during the same manufacturing operations, eliminating the need for separate speaker box production and assembly steps
Solution Approach 2:
The front frame and rear case structures serve themselves by forming the speaker box enclosure as an integral part of their own construction. The extended inner surfaces automatically create the enclosed space needed for the speaker box without requiring additional components or assembly operations

AI summary
A loudspeaker structure (40) for a flat display comprises a shield structure (42) and a speaker driver (45). The shield structure (42) is formed by integratedly extending a front frame (10) and a rear case (20) which are used to assemble the flat display. The shield structure (42) and the speaker driver (45) surround or confine a space and are used to construct a speaker box for the loudspeaker (40). The present invention utilizes the front frame (10) and the rear case (20) to be integratedly extended to form the speak box and in such manner that the cost for equipping the flat display with the loudspeaker (40) can be reduced and audio performance can be improved as well.
