Display Panel Sound Generation via Vibration and Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face issues with sound quality due to speakers being positioned below or behind the display panel, leading to sound being directed away from the user and interference with surrounding surfaces, which affects immersion and sound clarity.
Innovation Solution
A display apparatus with a sound generation device that vibrates the display panel to direct sound towards the front, utilizing a supporting member and partition structure to enhance sound output and reduce wave phenomena, allowing sound to be projected directly towards the user while minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a speaker is provided in the display apparatus, then sound can be generated, but the sound advances toward the lower or rear portion of the display panel instead of the front portion, disrupting user immersion
Solution Approach 1:
The patent inverts the conventional speaker placement by positioning the sound generation device at the front surface of the display panel instead of the rear or lower portion. This inversion allows sound to propagate directly toward the user, resolving the contradiction between sound generation capability and user immersion.
Solution Approach 2:
The patent changes the spatial dimension of sound output by transitioning from rear/lower direction to front direction. The sound generation device is configured to emit sound waves in the forward direction perpendicular to the display panel surface, creating a new spatial dimension for audio output that enhances user experience.
2Object-generated harmful factors
If a speaker is provided in the display apparatus, then sound can be generated, but sound quality is deteriorated due to interference with sound reflected on the wall or floor
Solution Approach 1:
The patent inverts the sound propagation direction to prevent reflection interference. By directing sound forward from the display panel surface rather than downward or rearward, the sound waves avoid reflecting off walls and floors, thereby maintaining sound quality without degradation from environmental reflections.
3Object-generated harmful factors
If a speaker is included in a set apparatus, then sound can be provided, but the speaker occupies space that imposes restriction on design and spatial disposition
Solution Approach 1:
The patent merges the sound generation function with the display panel structure itself. The sound generation device is integrated into the front surface of the display panel, combining two functions (visual display and audio output) into a single unified structure, thereby eliminating the need for separate speaker spaces and reducing design restrictions.
Solution Approach 2:
The display panel is designed to serve multiple functions: it acts as both the visual display surface and the sound generation surface. This multi-functionality allows the apparatus to provide both image and sound output through a single component, reducing overall device complexity and spatial requirements.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively enhances sound quality by directing sound towards the user and reducing interference, improving the overall audio experience by ensuring sound waves travel directly to the viewer without being disrupted by surrounding surfaces.
