Display Panel Sound Vibration via Rear-Mounted Transducer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in directing sound output to the front of the display panel, leading to deteriorated sound quality due to sound interference with walls or floors and occupy space, limiting design and arrangement options.
Innovation Solution
A display apparatus with a sound generating device attached to the rear surface of the display panel, utilizing a supporting member, partitions, and an adhesion member to optimize sound vibration and direct sound output to the front, eliminating the need for additional speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a speaker is provided in the display apparatus, then sound can be generated, but the sound advances toward the lower or rear side of the display panel instead of the front side, disrupting user immersion and deteriorating sound quality due to interference with walls or floors
Solution Approach 1:
The sound generating device is inverted from the conventional configuration where the speaker faces forward, to a configuration where the sound generating device is attached to the rear surface of the display panel with the diaphragm facing the rear surface. This inversion causes sound waves to propagate forward through the display panel itself, achieving front-direction sound output and eliminating interference with walls or floors.
Solution Approach 2:
The display panel serves as an intermediary medium for sound transmission. Instead of the speaker directly projecting sound forward, the sound generating device vibrates the rear surface of the display panel, which then transmits the sound waves through the panel material to the front side, enabling the panel to act as a sound transmission medium.
2Ease of operation
If a speaker is provided in the display apparatus, then sound can be generated, but the speaker occupies space causing limitations on design and arrangement of the set apparatus
Solution Approach 1:
The sound generating device is merged with the display panel structure itself. The sound generating device is attached to the rear surface of the display panel, utilizing the panel's structure as part of the sound generation system. This merging eliminates the need for separate speaker units and reduces overall device complexity and space requirements.
Solution Approach 2:
The display panel serves multiple functions: it acts as both the display surface and the sound transmission medium. By making the display panel universal for both visual and auditory output, the need for separate dedicated speaker components is eliminated, simplifying the overall device architecture.
