Engineering Contradiction Analysis
1Illumination intensity
If an open acoustic chamber design is adopted to achieve high-quality audio performance, then audio quality is improved, but shell resonance and vibrations are intensified
Solution Approach 1:
A damping medium is introduced as an intermediary substance between the airflow and the shell structure. The damping medium absorbs and dissipates the mechanical energy from turbulent airflow, preventing it from transmitting to the shell and causing resonance, while allowing the acoustic chamber to remain open for audio performance
Solution Approach 2:
The physical state and properties of the chamber environment are changed by introducing a damping medium with specific damping characteristics. This modifies the energy transmission parameters within the chamber, reducing the coupling between airflow turbulence and shell vibration while preserving acoustic functionality
2Object-affected harmful factors
If a damping medium is filled in the open acoustic chamber to reduce resonance, then shell resonance is reduced, but device structure becomes more complex
Solution Approach 1:
A porous damping medium is used to fill the damping chamber. The porous structure provides effective damping through its internal friction and viscosity characteristics while occupying minimal space and integrating seamlessly into the existing acoustic chamber design, avoiding additional complex structural modifications
Solution Approach 2:
The damping medium is nested within the existing acoustic chamber structure, utilizing the available internal space without requiring external additions or major structural redesigns. The damping chamber is formed by existing structural components (housing, cover, functional modules), integrating the damping function into the current device architecture
