Display Panel Vibration for Front-Facing Audio Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face issues with sound quality and aesthetics due to speakers being positioned at the lower or rear portion, leading to disrupted user immersion and compromised sound quality from interference with surrounding surfaces.
Innovation Solution
A display apparatus with a sound generation device that vibrates the display panel to direct sound forward, integrated with a supporting member and wiring system hidden from view to enhance aesthetics and reduce spatial constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a speaker is provided in the display apparatus, then sound can be supplied, but the sound advances toward the lower or rear portion instead of the front portion, disrupting user immersion
Solution Approach 1:
Instead of placing the speaker at the lower or rear portion of the display apparatus, the patent inverts the conventional arrangement by positioning the speaker at the front portion, allowing sound to propagate directly toward the user for improved immersion experience
2Ease of operation
If a speaker is provided in the display apparatus, then sound can be supplied, but sound quality is deteriorated due to interference with sound reflected on the wall or floor
Solution Approach 1:
The patent inverts the conventional speaker placement by positioning it at the front portion of the display apparatus rather than at the lower or rear portion, enabling sound to propagate forward without interference from reflections off walls or floor, thereby improving sound quality
3Ease of operation
If a speaker is included in a set apparatus, then sound can be supplied, but the speaker occupies space and imposes restriction on design and spatial disposition
Solution Approach 1:
The patent merges the speaker with the display panel by integrating it into the front portion of the display apparatus structure, allowing the speaker to share the same spatial envelope as the display panel and eliminating the need for separate speaker space, thereby preserving design freedom and spatial disposition flexibility
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 directing sound towards the user and maintains a sleek design by hiding the sound generation device and wiring, thereby enhancing both audio experience and visual appeal.
Implementation Method 1
A display apparatus vibrates a display panel to generate sound
