Solution Overview
Problem
Electronic devices with full screens face challenges in achieving balanced sound pressure levels across low and high frequencies using traditional vibrators, leading to suboptimal sound quality and increased power consumption due to inflexible vibrator arrangements.
Innovation Solution
A vibrator apparatus comprising multiple vibrators with varying thicknesses, areas, and shapes of bonding faces, allowing for flexible arrangements and improved sound generation, which balances sound pressure levels and reduces power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single vibrator is used to generate sound, then the device structure is simple, but the sound pressure level is not balanced across low and high frequencies
Solution Approach 1:
The patent divides the single vibrator into multiple vibrators (first vibrator and second vibrator) with different bonding face areas. The first vibrator has a larger bonding face area optimized for low frequency sound generation, while the second vibrator has a smaller bonding face area optimized for high frequency sound generation. This segmentation allows each vibrator to specialize in specific frequency ranges, achieving balanced sound pressure levels across the frequency spectrum.
2Reliability
If multiple vibrators with different specifications are used to balance sound pressure, then sound quality improves, but device complexity increases
Solution Approach 1:
The patent applies local quality by giving each vibrator distinct properties tailored to its function. The first vibrator is designed with a larger bonding face area specifically for low frequency optimization, while the second vibrator has a smaller bonding face area for high frequency optimization. This localized differentiation in vibrator specifications enables precise control over frequency-specific sound pressure levels without requiring complex overall system architecture.
3Ease of manufacture
If traditional vibrator arrangements are used, then manufacturing is simple, but power consumption is high due to inefficient sound generation
Solution Approach 1:
The patent changes the key parameter of bonding face area to optimize power consumption. By configuring the first vibrator with a larger bonding face area and the second vibrator with a smaller bonding face area, the system achieves more efficient sound generation across different frequencies. This parameter differentiation allows each vibrator to operate more efficiently in its optimized frequency range, reducing overall power consumption compared to using identical vibrators for all frequency ranges.
