Speaker Edge Reinforcement for Rolling Motion Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
General speaker apparatuses experience a rolling motion at specific frequencies due to unbalanced weight and support, leading to abnormal sounds and potential damage from seesaw motion, which existing technologies fail to sufficiently suppress.
Innovation Solution
A speaker apparatus design featuring a reinforcement part on the edge with a linear portion extending in the circumferential direction and end portions connected to the frame, increasing the edge's rigidity to suppress rotational displacement without obstructing vibration in the sound emission direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the edge is made more rigid to suppress rolling motion, then the rolling motion is suppressed, but the vibration in the sound emission direction is obstructed
Solution Approach 1:
The reinforcement part is provided only at specific positions on the edge where rolling motion occurs, rather than making the entire edge uniformly rigid. This localized reinforcement suppresses rolling motion while leaving other areas of the edge flexible enough to allow normal vibration in the sound emission direction.
Solution Approach 2:
The edge is divided into multiple segments by providing reinforcement parts at specific intervals rather than as a continuous rigid structure. This segmentation allows the edge to maintain rigidity at reinforcement locations to suppress rolling motion while remaining flexible between reinforcements to permit normal vibration.
2Stability of the object's composition
If reinforcement is added to the edge to suppress seesaw motion, then the seesaw motion is suppressed, but the device complexity increases
Solution Approach 1:
The reinforcement part is integrated with the edge as a unified structure, where the reinforcement part and edge work together as a single functional unit. This merging approach suppresses seesaw motion through the combined structure without requiring separate independent components, thereby reducing overall device complexity.
Solution Approach 2:
The reinforcement part and edge form a composite structure that combines different structural characteristics - the reinforcement part provides rigidity for seesaw motion suppression while the edge maintains flexibility for vibration. This composite approach achieves stabilization without significantly increasing complexity.
