Speaker Box Support Structure for Stronger Welded Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speaker boxes with irregularly shaped housings face challenges in achieving strong fixation strength and drop reliability due to limited welding areas and adhesive accumulation, which compromises the structural integrity and durability.
Innovation Solution
A speaker box design featuring a support member with first and second fixation portions welded to the yoke and housing, respectively, and a support portion connecting them, along with a metallic structure and hollow portions to enhance fixation strength and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the speaker unit is welded directly to the housing, then the fixation strength is improved, but the welding area is limited and welding strength is low for irregularly shaped housings
Solution Approach 1:
A support member is introduced as an intermediary component between the speaker unit and the housing. The support member includes a first fixation portion welded to the speaker unit, a second fixation portion welded to the housing, and a support portion connecting them. This mediator enables reliable fixation even when direct welding between speaker unit and housing is difficult due to irregular housing shapes.
2Strength
If adhesive is applied on periphery of the speaker unit to achieve further fixation, then the fixation strength is improved, but adhesive accumulation occurs and fixation strength is still difficult to ensure
Solution Approach 1:
The support member serves as a mechanical intermediary that provides structured fixation points, replacing the need for adhesive application on the periphery of the speaker unit. The first and second fixation portions of the support member create defined welding locations, eliminating adhesive accumulation issues while ensuring reliable fixation strength.
3Reliability
If the speaker unit is mounted inside the housing, then the sound quality is improved, but the drop reliability is compromised due to insufficient fixation strength
Solution Approach 1:
The support member acts as a reinforcing intermediary structure that enhances the mechanical connection between the speaker unit and housing. By providing a dedicated support portion and multiple fixation portions, it ensures sufficient fixation strength to maintain drop reliability while keeping the speaker unit properly mounted inside the housing.
Solution Approach 2:
The support member integrates multiple functional portions (first fixation portion, second fixation portion, and support portion) into a composite structure that combines welding capabilities with mechanical support, creating a unified fixation system that addresses both mounting and reliability requirements.
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 design improves fixation strength and drop reliability by stabilizing the speaker unit within the housing, prolonging the speaker box's lifespan and ensuring robust assembly.
Implementation Method 1
the first fixation portion is welded to the bottom surface; the second fixation portion is welded to the housing
