Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If upper shells and lower shells are not fixedly connected, then assembly is easier and manufacturing is simpler, but the vibration system becomes prone to deformation affecting sound quality
Solution Approach 1:
The mounting member is divided into a body portion and a bending portion, where the body portion receives the magnet assembly and the bending portion extends to the connector to provide fixed connection. This segmentation allows the structure to be assembled easily while maintaining structural strength through the specific functional division of parts.
Solution Approach 2:
The bending portion extends from the body portion in a direction toward the connector, creating a spatial arrangement that provides both easy assembly and structural strength. By utilizing the spatial dimension and the bending geometry, the connection is strengthened without complicating the assembly process.
2Ease of operation
If the vibration system is not fixedly connected, then the structure is more flexible and easier to assemble, but deformation occurs during vibration reducing sound quality
Solution Approach 1:
The mounting member is segmented into a body portion for receiving the magnet assembly and a bending portion for fixed connection to the connector. This segmentation enables easy assembly while the bending portion specifically addresses vibration stability by providing a rigid fixed connection that prevents deformation during operation.
Solution Approach 2:
The bending portion acts as an intermediary element between the body portion and the connector, providing a fixed connection that ensures vibration stability. This intermediary structure maintains reliability during vibration while allowing easy assembly of the overall speaker system.
3Ease of manufacture
If the mounting member is not fixed to the connector, then manufacturing and assembly are simpler, but the overall strength of the speaker decreases causing deformation
Solution Approach 1:
The mounting member is segmented into a body portion and a bending portion, where the bending portion specifically provides the fixed connection to the connector. This segmentation maintains manufacturing simplicity while the bending portion ensures overall structural strength by preventing deformation of the speaker during vibration.

AI summary
Provided is a speaker, including: a connector and a magnetic circuit unit and a vibration system that are fixed to the connector. The vibration system includes a first diaphragm fixed to the connector and a voice coil driving the first diaphragm to vibrate and sound. The magnetic circuit unit includes a magnet assembly providing driving force to the voice coil and a mounting member fixing the magnet assembly. A bending portion is formed by bending from an edge of the mounting member toward the first diaphragm, and the bending portion is fixedly connected to the connector. With this structure, the first diaphragm is fixedly connected to the mounting member, so as to strengthen the overall strength of the speaker and prevent the deformation of the speaker in its vibrating direction, thereby improving the quality of the speaker.
