Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speaker modules face challenges in forming and installing air-permeable insulation assemblies with irregular shapes, leading to issues like mesh breakage and deviation, which reduce production yield.
Innovation Solution
The speaker module incorporates a support frame with a mesh cloth fixed using a double-sided adhesive, and a clamping wall with elastic pads to securely attach the air-permeable insulation assembly, preventing mesh deviation and breakage while accommodating irregular shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If mesh cloth is injected onto support frame using injection molding, then air-permeable insulation assembly can be formed, but mesh breakage and mesh deviation occur leading to low production yield
Solution Approach 1:
The invention divides the air-permeable insulation assembly into two separate components: a support frame and a mesh cloth. The support frame is formed separately via injection molding, and the mesh cloth is separately positioned and fixed onto the support frame. This segmentation allows each component to be manufactured and assembled independently, avoiding the mesh breakage and deviation issues that occur when attempting to inject mesh cloth directly onto the support frame as a single integrated component.
2Adaptability or versatility
If air-permeable insulation assembly is formed with irregular shape, then acoustic performance can be optimized, but molding process becomes difficult and yield decreases
Solution Approach 1:
By segmenting the air-permeable insulation assembly into a support frame and mesh cloth, the invention enables the support frame to be manufactured with complex irregular shapes via injection molding without affecting the mesh cloth. The mesh cloth can then be conformally attached to the irregularly shaped support frame, achieving optimized acoustic performance while maintaining manufacturing feasibility.
Solution Approach 2:
The support frame serves as an intermediary component that bridges the manufacturing process and the final irregular shape requirement. The support frame is first formed with the desired irregular shape through injection molding, then the mesh cloth is positioned and fixed onto this pre-formed support frame, allowing the mesh to conform to the irregular shape without direct injection molding of the mesh itself.
3Productivity
If mesh cloth is directly injected onto support frame, then assembly can be formed, but mesh breakage occurs during injection process
Solution Approach 1:
The invention segments the assembly process into separate steps: first forming the support frame via injection molding, then separately positioning and fixing the mesh cloth onto the support frame. This eliminates the direct injection of mesh cloth onto the support frame, thereby preventing mesh breakage while maintaining productivity through efficient sequential assembly.

Implementation Method 1
a mesh cloth adhered and fixed to the support frame by means of a back adhesive
Implementation Method 2
the elastic pad is compressed when the air-permeable insulation assembly is inserted into the clamping wall to seal the air-permeable insulation assembly and the clamping wall
Implementation Method 3
after the current is input into the voice coil, it vibrates under the ampere force of the magnetic field formed by the magnetic circuit assembly, and in turn drives the diaphragm to vibrate and produce the sound
Implementation Method 4
sound-absorbing materials are arranged in the rear acoustic cavity
