Panel Bottom Assembly Vibration Acoustic Device Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices require separate speakers to produce sound, which increases their size and complexity, as they are limited to displaying images without integrated sound-producing capabilities.
Innovation Solution
Incorporating a vibration acoustic device within the panel bottom member, utilizing a piezoelectric material layer that generates vibrations in response to acoustic signals, allowing the display panel to function as a diaphragm and produce sound without the need for separate speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate speakers are used to produce sound, then sound output is achieved, but device size and complexity increase
Solution Approach 1:
The patent combines the sound-producing function with the display panel by integrating a vibration acoustic device behind the display panel. The display panel itself serves as the diaphragm, merging two separate functions (display and sound output) into a single integrated structure, thereby reducing device complexity while maintaining sound-producing capability
Solution Approach 2:
The display panel is given multiple functions: it serves both as the display surface and as the diaphragm for sound production. The vibration acoustic device integrated behind the panel enables the panel to perform both visual display and acoustic output, achieving multi-functionality and eliminating the need for separate speaker components
2Volume of moving object
If separate speakers are used to produce sound, then sound output is achieved, but device size increases
Solution Approach 1:
The patent merges the speaker function into the display panel structure by placing the vibration acoustic device directly behind the panel. This integration eliminates the need for separate speaker housings and components, reducing the overall device volume while preserving sound-producing capability
Solution Approach 2:
The vibration acoustic device is nested within the structure of the display panel assembly, with the acoustic device positioned in the space behind the panel. This nesting approach allows the sound-producing components to occupy minimal additional space, effectively reducing device size while maintaining audio functionality

AI summary
A panel bottom assembly includes a light-blocker with first concave patterns formed on a top surface thereof. A vibration acoustic device is disposed below, and coupled to, the light-blocker. A buffer is disposed below the light-blocker. A bonding is disposed between the light-blocker and the vibration acoustic device. The bonding has second concave patterns formed on a top surface thereof. The second concave patterns are different from the first concave patterns.
