Display Panel Vibration Control via Intermediary Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face issues with sound distortion and deterioration due to the rolling phenomenon in vibration generators, which disrupt the immersion experience and aesthetic design by directing sound away from the user and occupying space.
Innovation Solution
Incorporating a supporting member between the display panel and the vibration generator to maintain distance and prevent rolling, thereby improving sound quality and design by ensuring sound is directed towards the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vibration generator is used to vibrate the display panel for sound output, then sound can be directed toward the user, but a rolling phenomenon occurs causing sound distortion and deterioration
Solution Approach 1:
A supporting member is introduced as an intermediary component between the display panel and the vibration generator. This supporting member maintains a specific distance between the vibration generator and the display panel, preventing direct contact that causes the rolling phenomenon while still allowing effective vibration transmission for sound output toward the user.
2Adaptability or versatility
If a separate speaker is provided in the display apparatus, then sound can be supplied, but it occupies space and disrupts the user's immersion experience by directing sound away from the user
Solution Approach 1:
The patent merges the sound output function with the existing display panel structure by using the vibration generator to vibrate the display panel itself. This eliminates the need for a separate speaker component, saving device space while directing sound toward the user through the front surface of the display panel, thereby maintaining immersion experience.
3Productivity
If the vibration generator is placed close to the display panel, then sound output efficiency is improved, but the rolling phenomenon occurs causing the vibration generator to operate abnormally
Solution Approach 1:
The supporting member serves as a mediator that maintains an optimal distance between the vibration generator and the display panel. This distance is carefully controlled to ensure sufficient sound output efficiency while preventing the rolling phenomenon that occurs when the components are too close, thereby maintaining stable operation of the vibration generator.
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 reduces or prevents rolling phenomena, enhancing sound quality and immersion experience by ensuring sound is directed towards the user, while also improving the aesthetic design by eliminating the need for a separate speaker space.
