Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple speakers are used in a sound bar, then sound pressure characteristics are improved, but acoustic interference occurs among speakers
Solution Approach 1:
The sound bar is divided into multiple independent vibration units, each containing its own vibration part and support member structure. This segmentation allows each speaker to operate independently with optimized acoustic characteristics while maintaining overall sound pressure output.
Solution Approach 2:
A cover member is introduced as an intermediary structure between multiple vibration parts. This cover member serves as a mediator that manages acoustic interactions between speakers, preventing harmful acoustic interference while allowing beneficial sound pressure reinforcement.
2Power
If multiple speakers are used in a sound bar, then sound pressure characteristics are improved, but directionality is compromised
Solution Approach 1:
Each vibration part is equipped with its own dedicated support member and cover member structure, creating localized acoustic optimization zones. This local quality approach ensures that each speaker maintains its directional characteristics while contributing to overall sound pressure.
Solution Approach 2:
The invention introduces a vertical dimension with the cover member extending over the vibration parts. This dimensional addition creates acoustic isolation in the vertical direction while maintaining horizontal sound projection, thereby preserving directionality despite multiple speakers.
