Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional earphone design is used, then the structure is simple and easy to manufacture, but the earphone cannot provide tactile vibration experience
Solution Approach 1:
The patent combines the sound output function and vibration output function into a single earphone device. The vibratile terminal is integrated with the speaker system, allowing both audio output and tactile feedback through the same device structure, thus providing enhanced sensory experience without requiring completely separate systems.
Solution Approach 2:
The earphone is designed to perform multiple functions: traditional sound output through speaker and additional tactile vibration output through the vibratile terminal. This multi-functionality allows the device to provide both auditory and tactile feedback, enhancing the user experience in scenarios like music listening and gaming.
2Reliability
If vibration components are added to earphone, then the sense of shock is improved, but the device complexity increases
Solution Approach 1:
The low-frequency detection control circuit proactively detects low-frequency signals in the audio output and generates control signals to activate the vibratile terminal before the user would otherwise perceive only auditory information. This preliminary detection and activation sequence ensures that vibration feedback is synchronized with the audio content, enhancing the sense of shock without requiring complex real-time processing.
Solution Approach 2:
The low-frequency detection control circuit serves as an intermediary between the audio signal source and the vibratile terminal. It detects low-frequency components in the audio signal and translates them into appropriate control signals for the vibratile terminal, enabling coordinated vibration feedback without direct complex coupling between the audio and vibration systems.
3Reliability
If vibration is transmitted through headband and speaker chambers, then immersion is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The vibration transmission path is segmented into distinct components: the vibratile terminal generates vibration, vibration guiding columns transmit the vibration, and vibration gum covers provide contact with the headband and speaker chambers. This segmentation allows each component to be optimized and manufactured separately, reducing the overall manufacturing precision requirements while maintaining effective vibration transmission for immersion.
