The sound generator design includes a housing with adjustable case and cover width portions, allowing for easy modification of the space between components to alter acoustic characteristics, and a partition wall with matching shapes for different sound generating bodies, enabling flexible assembly and resonance chamber formation to enhance sound pressure across a wide frequency band.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the case and cover are designed as fixed single-piece structures, then the manufacturing process is simple, but the acoustic characteristics cannot be adjusted
Solution Approach 1:
The housing is divided into multiple segments: the base, the case with case width adjustment portions, and the cover with cover width adjustment portions. These segments can be independently manufactured and then assembled, allowing the acoustic characteristics to be adjusted by modifying the width of specific portions without redesigning the entire housing structure.
Solution Approach 2:
The case and cover incorporate width adjustment portions that can be dynamically modified in width. By changing the width of these portions, the internal volume and acoustic characteristics of the housing can be adjusted to meet different customer requirements, transforming a static structure into a dynamically adaptable one.
2Adaptability or versatility
If different housing designs are created for each acoustic requirement, then the acoustic characteristics can be optimized, but the design and manufacturing time increases
Solution Approach 1:
The housing design serves multiple functions: it provides structural support, houses the sound generating body, and allows acoustic characteristic adjustment. The width adjustment portions in the case and cover enable a single housing design to fulfill multiple acoustic requirements, eliminating the need to create entirely new designs for each application.
Solution Approach 2:
The acoustic characteristics are adjusted by changing the width parameter of the case width adjustment portions and cover width adjustment portions. This parameter-based adjustment approach allows for quick customization of acoustic properties without requiring complete redesign, thereby maintaining high productivity while achieving acoustic optimization.
3Adaptability or versatility
If the case width adjustment portion and case rear portion are made as separate members, then the acoustic adjustment flexibility increases, but the manufacturing cost increases
Solution Approach 1:
The case width adjustment portion and case rear portion are merged into a single integrated case structure. This integration reduces the number of separate components, simplifies the assembly process, and lowers manufacturing costs while still allowing the width of the adjustment portion to be modified for acoustic tuning.
