Display Panel Vibration Structure for Screen-Integrated Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses and computing devices suffer from degraded sound quality due to sound interference and inadequate low-pitched and high-pitched sound output, leading to reduced viewer immersion.
Innovation Solution
A display apparatus and computing apparatus that utilize a vibration module integrated with a display panel to output sound, featuring a vibration plate, connection member, and enclosures to enhance sound characteristics and direct sound towards the viewer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sound devices are disposed on lower side and spaced apart from screen, then device structure is simplified, but sound quality and viewer immersion are degraded
Solution Approach 1:
The patent merges the sound output function with the display panel by integrating a vibration module directly onto the rear surface of the display panel. This combination eliminates the need for separate speakers spaced apart from the screen, thereby maintaining structural simplicity while dramatically improving sound quality and viewer immersion through direct vibration transfer to the panel surface.
Solution Approach 2:
The patent transitions from traditional spatial sound output (separate speakers positioned away from the display) to a dimensional integration where the vibration module operates in the same plane as the display panel. By placing the vibration module on the rear surface of the display panel and utilizing the panel itself as the sound radiation surface, the invention achieves both structural simplicity and superior sound quality.
2Object-affected harmful factors
If vibration module is placed close to display panel, then sound quality improves, but horizontal vibration and distortion increase
Solution Approach 1:
The patent applies local quality by positioning enclosures at specific locations around the vibration module rather than uniformly across the entire display panel. The enclosures are strategically placed to surround the vibration module and provide localized damping, allowing the majority of the display panel to maintain its vibration freedom for sound radiation while controlling distortion at the source.
Solution Approach 2:
The enclosures act as intermediary elements between the vibration module and the display panel. These enclosures provide a controlled interface that allows the vibration module to generate sound while simultaneously damping horizontal vibrations and preventing excessive distortion from propagating across the entire panel surface.
3Stability of the object's composition
If enclosures are added to control vibration, then horizontal vibration decreases, but device complexity increases
Solution Approach 1:
The patent implements nesting by placing the vibration module within enclosures that are themselves positioned on the rear surface of the display panel. This nested configuration allows the enclosures to be integrated into the overall display structure rather than being added as external components, thereby controlling horizontal vibration while minimizing the increase in device complexity.
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
Improves sound quality by enhancing low-pitched and high-pitched sound output, creating a harmonious sound field that fills the entire screen, and increases viewer immersion.
Implementation Method 1
a vibration module on the vibration plate, wherein the display module vibrates according to vibration of the vibration plate
Implementation Method 2
the enclosure may be near the vibration module to dampen horizontal vibration of the vibration plate
