Solution Overview
Problem
The challenge is to effectively couple a speaker to a display device frame while minimizing vibrations, maintaining thinness, and reducing manufacturing costs, without compromising image quality or causing volume loss.
Innovation Solution
A sound device structure that includes a frame, a speaker adjacent to the frame, a coupling part on the speaker, and a holder positioned between the frame and the coupling part, where the holder penetrates the frame to securely attach the speaker, utilizing a soft material to isolate vibrations and maintain a slim design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a speaker is directly attached to the frame, then the coupling is simple and manufacturing cost is low, but vibrations are transmitted to the frame causing image quality degradation
Solution Approach 1:
A holder is introduced as an intermediary component between the speaker and the frame. The holder includes a first portion coupled to the speaker and a second portion coupled to the frame, acting as a mediator that prevents direct contact and vibration transmission while maintaining the coupling function.
Solution Approach 2:
The holder is configured with composite structural characteristics, combining rigidity for stable coupling with vibration isolation properties. The holder's design integrates multiple functional properties to simultaneously achieve stable attachment and vibration minimization.
2Length of moving object
If the speaker thickness is reduced to maintain thin display device, then the overall device thickness is reduced, but the speaker coupling stability and vibration isolation are compromised
Solution Approach 1:
The holder extends in the thickness direction (z-axis) with a configured length that provides sufficient coupling stability. By utilizing the thickness dimension effectively, the holder achieves stable speaker attachment without increasing the overall device thickness, as the holder's structure is optimized to fit within the available space.
Solution Approach 2:
The coupling structure is segmented into multiple portions: the holder's first portion coupled to the speaker and the second portion coupled to the frame. This segmentation allows each portion to be optimized for its specific function while maintaining overall compactness and stability.
3Object-affected harmful factors
If a holder structure is introduced to isolate vibrations, then vibration transmission is minimized, but manufacturing cost and structural complexity increase
Solution Approach 1:
The holder is designed as a multi-functional component that simultaneously provides vibration isolation, mechanical coupling, and positional alignment. By integrating multiple functions into a single component, the overall device complexity is reduced compared to using separate components for each function.
Solution Approach 2:
The holder merges the functions of vibration isolation and mechanical coupling into a single integrated structure. The first portion and second portion of the holder work together as a unified component, eliminating the need for separate isolation elements and simplifying the overall coupling structure.
