Display Panel Vibration for Forward Sound Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in directing sound output towards the viewer, resulting in degraded sound quality due to sound waves being directed rearward or downward, and occupy space with separate speakers, limiting design and immersion experience.
Innovation Solution
A display apparatus with a sound generating device that vibrates the display panel to produce sound, eliminating the need for separate speakers and enhancing sound directionality, while also being slimmed and integrated between the display panel and supporting member to reduce thickness and improve aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate speaker is installed in a display apparatus, then sound can be provided, but the sound travels toward the rear surface or region under the display panel instead of toward the front surface, degrading sound quality and immersion experience
Solution Approach 1:
The patent combines the sound generating device with the display panel structure by integrating it between the display panel and supporting member. This merging eliminates the need for separate speakers and enables sound to be generated in the forward direction toward the viewer, resolving the contradiction between sound directionality and sound quality.
Solution Approach 2:
The patent changes the spatial dimension of sound generation by positioning the sound generating device between the display panel and supporting member, allowing sound to propagate in the forward direction (toward the front surface) rather than backward or downward, thus improving both sound directionality and quality.
2Ease of operation
If a separate speaker is installed in a display apparatus, then sound can be provided, but the speaker occupies certain space, limiting design and space disposition flexibility
Solution Approach 1:
The sound generating device is merged with the display panel structure, eliminating the need for separate speaker components. This integration reduces the overall space occupied and provides greater design flexibility for the display apparatus.
Solution Approach 2:
The display panel structure serves multiple functions: displaying images and generating sound. By making the display panel structure multi-functional, the patent eliminates the need for dedicated speaker space, thereby improving design flexibility and reducing space occupation.
3Length of stationary object
If a sound generating device is integrated between the display panel and supporting member, then the apparatus thickness is reduced and design flexibility is improved, but the device complexity increases
Solution Approach 1:
The sound generating device is integrated into the existing structure between the display panel and supporting member. This merging approach reduces apparatus thickness while managing complexity by utilizing the existing structural space rather than adding separate components.
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
The solution effectively directs sound towards the viewer, enhancing sound quality and immersion, while reducing the apparatus's thickness and improving design flexibility by integrating the sound generating device within the display panel structure.
Implementation Method 1
at least one sound generating device between the display panel and the supporting member coupled by the coupling member to the supporting member, the at least one sound generating device being configured to vibrate the display panel to generate sound
