Mobile Terminal Speaker Assembly with Shock-Absorbing Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal apparatuses face challenges in reducing the installation volume of speaker apparatuses while maintaining sound quality due to large contact areas between the speaker and the shell, leading to resonance and affecting user experience.
Innovation Solution
A speaker assembly with a top plate featuring mounting bases and a shell with convex parts connected by fasteners, reducing the contact area and resonance between the speaker and the shell, and incorporating shock absorbing layers and heat dissipation holes to improve sound quality and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the speaker is directly mounted on the shell with large contact area, then the installation is simple and stable, but resonance occurs and sound quality deteriorates
Solution Approach 1:
A shock absorbing sleeve is introduced as an intermediary component between the fastener and the mounting base. This sleeve reduces the contact area between the speaker and shell while providing shock absorption functionality, thereby eliminating resonance without compromising mounting stability
Solution Approach 2:
The shock absorbing sleeve is positioned specifically at the contact points between the fastener and mounting base. This localized intervention reduces contact area only where necessary (at the mounting points) while maintaining overall speaker stability, preventing resonance without affecting the entire speaker assembly
2Object-generated harmful factors
If the contact area between speaker and shell is reduced, then resonance is reduced and sound quality improves, but the speaker may become unstable
Solution Approach 1:
The shock absorbing sleeve acts as a mediator that simultaneously achieves two opposing goals: it reduces contact area to eliminate resonance while maintaining mounting stability through its shock absorption and positioning capabilities
Solution Approach 2:
The shock absorbing sleeve is made of shock absorbing material, representing a composite or specialized material that provides both structural support for stability and vibration damping for resonance reduction
3Volume of moving object
If the mobile terminal apparatus volume is reduced, then portability improves, but the speaker installation volume must be minimized which complicates the mounting structure
Solution Approach 1:
The mounting structure is segmented into distinct functional components: mounting bases on the speaker, convex parts on the shell, and shock absorbing sleeves on the fasteners. This segmentation allows each component to be optimized independently for small size while maintaining overall functionality
Solution Approach 2:
The shock absorbing sleeve functions as a flexible or compliant element that can be compressed or deformed to accommodate tight spaces. This flexibility allows the mounting structure to be compact while still providing adequate shock absorption and stable mounting
