Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the elastic component is used to suspend the second vibration system, then the vibration recovery is facilitated, but the vibration damping is large and the service life is short
Solution Approach 1:
The patent introduces a flexible circuit board as an intermediary element that couples the elastic component to the vibration system. This mediator allows the elastic component to provide vibration recovery while the flexible circuit board absorbs and distributes the mechanical stress, reducing the direct damping impact on the elastic component and thereby extending its service life.
Solution Approach 2:
The patent employs a composite structure combining the elastic component with the flexible circuit board. This composite system leverages the elastic properties of the elastic component for vibration recovery while utilizing the flexible and durable characteristics of the circuit board to reduce overall system damping and improve longevity.
2Device complexity
If the elastic component and flexible circuit board vibrate independently, then the structure is simple, but the stability is insufficient
Solution Approach 1:
The patent merges the elastic component and the flexible circuit board into a coupled vibration system through the connection component. This combination allows both elements to vibrate together in a coordinated manner, enhancing system stability while maintaining relatively simple structural implementation.
Solution Approach 2:
The flexible circuit board serves multiple functions: it provides electrical connections and simultaneously acts as a structural element that couples with the elastic component to enhance vibration stability. This multi-functionality achieves improved stability without significantly increasing structural complexity.
3Ease of operation
If the flexible circuit board is extended outside the containment cavity, then the connection is facilitated, but the structure becomes more complex
Solution Approach 1:
The patent employs a flexible circuit board that can dynamically extend and bend outside the containment cavity. This dynamic flexibility allows the circuit board to reach external connection points while accommodating the three-dimensional space constraints, achieving easy external connection without requiring rigid structural modifications.

AI summary
The present invention provides a multifunctional sounding device including a housing, a first vibration system, a second vibration system, a magnetic circuit system, an elastic component and a flexible circuit board. The elastic component includes a deformation part fixed to the second vibration system and an installation part extended from both ends of the deformation part and fixed to the housing. The second vibration system is suspended in the containment cavity through the elastic component. The flexible circuit board is connected with the elastic component, so that the vibration of the flexible circuit board is coupled with the vibration of the elastic component. Therefore, the damping of the elastic component is reduced, the force received by the elastic component during vibration is reduced, and the service life of the elastic component is extended.
