Speaker Anti-Vibration Pads for Display Noise Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In liquid crystal display products, strong speaker vibrations can lead to abnormal noise and adverse audio effects due to the lack of effective vibration mitigation in existing designs.
Innovation Solution
A displayer configuration that includes a display module, a speaker, and a housing with anti-vibration pads and members that restrain speaker vibrations, ensuring the audio effect is not adversely affected by strong vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the speaker is fixed using a simple back plate or fixing column structure, then the device complexity is reduced and ease of manufacture is improved, but the speaker vibration causes abnormal noise and adverse audio effects
Solution Approach 1:
The patent introduces anti-vibration pads as an intermediary component between the speaker and the fixing structure. These pads serve as a mediator that absorbs and dampens vibrations while still allowing the speaker to be securely mounted. The anti-vibration members on the baseplate work together with these pads to create an effective vibration isolation system without requiring complex manufacturing processes.
2Object-affected harmful factors
If anti-vibration members are added to restrain speaker vibration, then abnormal noise is reduced, but the device complexity increases
Solution Approach 1:
The patent applies anti-vibration members only at specific locations where vibration transmission occurs - namely on the baseplate at positions corresponding to the speaker mounting points. This localized application of vibration restraint features provides effective noise reduction without requiring the entire housing structure to be complex. The anti-vibration pads are also strategically placed only where needed for speaker mounting.
3Reliability
If the speaker is firmly fixed to prevent vibration, then audio quality is improved, but the structural flexibility and ability to accommodate strong vibrations are reduced
Solution Approach 1:
The patent creates a dynamic vibration management system where the anti-vibration pads can deform and absorb vibration energy while the anti-vibration members provide restrained resistance. This dynamic interaction allows the speaker to be firmly fixed for audio quality while simultaneously accommodating strong vibrations through the compliant anti-vibration elements that can flex and dampen vibration peaks.
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 anti-vibration members effectively mitigate speaker vibrations, maintaining audio quality without noise interference and enhancing structural integrity by distributing load and preventing dust entry.
Implementation Method 1
the speaker fixing member includes anti-vibration members configured to restrain a vibration of the speaker, and the anti-vibration members are in contact with the anti-vibration pads
