Existing sound generation devices face issues with elastic members resonating with the vibration unit, affecting the normal vibration trajectory and operation stability due to resonance.
Innovation Solution
A sound production apparatus is designed with a holder, vibration unit, elastic member, and damping member, where the elastic member connects the holder and vibration unit, and the damping member is provided on the elastic member to alter its resonance frequency, preventing resonance and ensuring stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If elastic members are fixed on voice coil bobbin to prevent polarization, then structural support is improved, but resonance occurs affecting vibration trajectory
Solution Approach 1:
A damping member is introduced as an intermediary element between the elastic member and the voice coil bobbin. This damping member serves as a mediator that suppresses resonance of the elastic member while maintaining its structural support function, thereby preventing negative effects on the vibration trajectory without compromising the structural support provided by the elastic member.
2Stability of the object's composition
If elastic member is used to connect holder and vibration unit, then structural stability is improved, but resonance frequency interference occurs
Solution Approach 1:
The damping member converts the harmful resonance phenomenon into a beneficial effect by dissipating vibrational energy. The damping member is specifically designed to have damping characteristics that counteract the resonance of the elastic member, transforming the potential harmful resonance into controlled energy dissipation that protects the vibration trajectory while maintaining structural stability.
