Display Panel Vibration Sound Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses suffer from poor sound quality due to speakers directing sound away from the viewer and occupying valuable space, limiting design and immersion.
Innovation Solution
Incorporating a sound generating device within the display panel that vibrates to direct sound towards the viewer, enhancing sound quality and reducing space usage by eliminating the need for external speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate speaker is installed in the display apparatus, then sound can be provided, but the speaker occupies space and limits design flexibility
Solution Approach 1:
The patent merges the sound generating device with the display panel by integrating the vibration generating device into the display panel structure. The vibration generating device is positioned at the rear surface of the display panel and uses the display panel itself as the vibration plate, eliminating the need for separate speakers and reducing overall device volume.
Solution Approach 2:
The display panel serves dual functions: displaying images and generating sound. By using the display panel as both the display medium and the vibration plate for sound generation, the invention achieves multi-functionality, allowing the same component to perform both display and audio output tasks.
2Ease of operation
If a separate speaker is installed in the display apparatus, then sound can be provided, but the speaker directs sound away from the viewer, reducing immersion
Solution Approach 1:
Instead of placing the speaker at the front of the display apparatus pointing toward the viewer, the invention inverts the approach by placing the vibration generating device at the rear surface of the display panel. This causes the display panel to vibrate and generate sound waves that travel forward through the panel toward the viewer, reversing the conventional speaker placement and direction.
3Ease of operation
If a separate speaker is installed in the display apparatus, then sound can be provided, but sound quality is degraded due to interference from reflected sound
Solution Approach 1:
The display panel acts as an intermediary medium between the vibration generating device and the viewer. By using the display panel as the vibration plate, sound waves are generated directly at the front surface of the panel, reducing the path length and minimizing interference from reflected sound waves off walls or floors.
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 solution improves sound immersion and quality by ensuring sound travels directly to the viewer, while also optimizing the design and space utilization within display devices.
Implementation Method 1
at least one sound generating device in the display panel, the at least one sound generating device being configured to vibrate the display panel to generate sound
Data Source
AI summary
A display apparatus includes a display panel configured to display an image, a supporting member configured to support the display panel, at least one sound generating device in the display panel, to the at least one sound generating device being configured to vibrate the display panel to generate sound, and a connection member at a lower portion of the supporting member to correspond to a center of the at least one sound generating device.
