Display Panel Vibration Sound Output for Slim Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in reducing weight and size while maintaining sound quality, as built-in speakers often direct sound away from the viewer due to their rear or side surface orientation, disrupting immersion.
Innovation Solution
A display apparatus with a sound generating device on its rear surface, utilizing a vibration mechanism that directs sound towards the front via a display panel, and an adhesive member strategically placed to enhance vibration characteristics, allowing sound to be output towards the viewer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a sound device is built in a display apparatus, then sound can be output, but the weight and size of the display apparatus increase
Solution Approach 1:
The display panel serves dual functions: visual display and sound generation. By utilizing the display panel itself as the sound output medium through vibration, the patent eliminates the need for separate sound devices, thereby maintaining sound output capability while avoiding additional weight and size increases
Solution Approach 2:
The patent merges the sound generation function with the display panel structure. The sound generating device is integrated onto the rear surface of the display panel, combining what would traditionally be separate components into a unified structure, thus avoiding additional weight and spatial requirements
2Power
If a sound device is built in a display apparatus, then sound can be output, but the size of the display apparatus increases
Solution Approach 1:
The display panel serves dual functions: visual display and sound generation. By utilizing the display panel itself as the sound output medium through vibration, the patent eliminates the need for separate sound devices, thereby maintaining sound output capability while avoiding additional weight and size increases
Solution Approach 2:
The sound generating device is nested onto the rear surface of the display panel, utilizing the existing structure and space. This nested configuration allows sound generation functionality to be incorporated without adding external dimensions or increasing the overall footprint of the display apparatus
3Power
If sound is generated by a sound device on rear or side surface, then sound can be output, but sound does not travel toward the viewer, disrupting immersion
Solution Approach 1:
Instead of placing the sound device in conventional positions (front or side) and directing sound outward, the patent inverts the approach by placing the sound generating device on the rear surface and using the display panel to project sound toward the front. This inverted configuration ensures sound travels directly toward the viewer, enhancing immersion
Solution Approach 2:
The display panel acts as an intermediary medium between the sound generating device and the viewer. The sound generating device vibrates the display panel, which then transmits and directs the sound waves toward the front surface, ensuring sound travels in the correct direction toward the viewer without requiring the sound device to be positioned in conventional locations
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
This configuration improves sound quality and immersion by effectively directing sound towards the viewer, while maintaining a slim and compact design for the display apparatus.
Implementation Method 1
a sound generating device on a rear surface of the display panel and including a first side and a second side perpendicular to the first side
Implementation Method 2
an adhesive member in a partial region of the sound generating device
