Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sounding devices in mobile communication devices have a complex structure due to the inclusion of a skeleton, which increases manufacturing costs, assembly complexity, and device weight.
Innovation Solution
The proposed sounding device eliminates the skeleton by integrating a protruded platform of the dome with the dome body, using a reinforcement element to stabilize the voice coil and conductive element, thereby reducing assembly complexity and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a skeleton is provided in the sounding device, then the position of the voice coil is adjusted and vibration amplitude symmetry is improved, but the number of parts increases, manufacturing cost increases, assembly process becomes more complex, and overall weight increases
Solution Approach 1:
The patent merges the dome part and suspension into a single integrated dome structure. The suspension is formed as an integral part of the dome, eliminating the need for separate skeleton components. This integration maintains the structural support function while reducing the total number of parts and simplifying manufacturing.
Solution Approach 2:
The integrated dome structure serves multiple functions simultaneously: it acts as the acoustic diaphragm, provides structural support, positions the voice coil, and maintains vibration symmetry. This multi-functional design replaces the specialized skeleton components with a single universal element.
2Manufacturing precision
If a skeleton is provided in the sounding device, then the position of the voice coil is adjusted and vibration amplitude symmetry is improved, but the assembly process becomes more complex
Solution Approach 1:
By combining the dome and suspension into one integral structure, the patent reduces the number of assembly steps. The voice coil is positioned and supported by the integrated dome structure, eliminating the need for separate skeleton assembly operations.
3Manufacturing precision
If a skeleton is provided in the sounding device, then the position of the voice coil is adjusted and vibration amplitude symmetry is improved, but the overall weight increases
Solution Approach 1:
The integration of dome and suspension into a single structure eliminates redundant materials and reduces overall weight while maintaining the structural integrity needed for vibration symmetry.
4Device complexity
If the voice coil and conductive element are connected only by voice coil wire, then the structure is simple, but the connection stability is insufficient and separation may occur
Solution Approach 1:
The reinforcement element merges the voice coil and conductive element into a more stable integrated connection. This additional structural bonding prevents separation while maintaining relative simplicity.
