Resonating Plate Speaker System for Flat Panel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with integrated speaker systems are aesthetically unpleasing, increase the device's size, and elevate manufacturing costs due to visible speakers and the need for additional attachment points.
Innovation Solution
The integration of a resonating plate that functions as part of the front panel, with exciters mounted to its rear surface, allowing the front panel to act as a speaker and reducing the need for separate speaker components, thereby minimizing visible speaker presence and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speakers are attached to the display device, then sound output function is improved, but aesthetic appearance deteriorates due to visible speakers
Solution Approach 1:
The patent merges the speaker system with the front panel structure by integrating exciters into the display module's front panel. The front panel itself becomes part of the speaker system, eliminating the need for separate visible speaker components while maintaining sound output function.
Solution Approach 2:
The front panel serves dual functions: it acts as both the display device's structural component and as part of the speaker system (resonating plate). This multi-functionality allows the same component to provide both structural support and acoustic output, improving aesthetics while maintaining sound functionality.
2Reliability
If separate speakers are attached to the display device, then sound output function is improved, but device size increases
Solution Approach 1:
The speaker system is merged with the display module structure. The exciters are integrated into the front panel, and the speaker system shares structural components with the display device, thereby avoiding additional volume that would result from separate speaker attachments.
Solution Approach 2:
The front panel and display module structure serve multiple functions: structural support, display housing, and acoustic resonance. This eliminates the need for additional dedicated speaker housing space, maintaining compact device dimensions.
3Reliability
If non-integrated speakers are used, then sound output function is improved, but manufacturing cost increases due to additional attachment holes
Solution Approach 1:
The speaker system is integrated into the display module's existing structure during the same manufacturing process. The front panel is formed with built-in exciter mounting structures, eliminating the need for separate attachment operations and additional manufacturing steps that would increase cost.
Solution Approach 2:
The front panel manufacturing process simultaneously creates both the display device housing and the speaker system mounting structure. This integrated approach allows a single manufacturing process to produce multiple functional components, reducing overall manufacturing complexity and cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances sound quality, reduces the overall size and thickness of the display device, and lowers manufacturing costs by utilizing the front panel as a resonating surface, while maintaining aesthetic appeal.
Implementation Method 1
an exciter (4) which is directly coupled to the rear surface of the resonating plate (3)
Implementation Method 2
a resonating plate (3) having the exciter (4) directly mounted to a rear surface thereof
Data Source
AI summary
At least one exciter is used to produce sound for a flat panel display. The exciter vibrates the housing for production of sound. The housing may also include a plate mounted on the front surface of the housing and the exciter may be attached to the plate, which serves as a resonance plate.
