Pinna Orientation Mechanism for Omnidirectional Auditory Sensitivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auditory sensitivity adjustment devices are limited in enhancing concentration and attentiveness as they primarily focus on sound collection from a specific direction, such as the front, and fail to effectively enhance sensitivity for sounds coming from other directions like the rear, sides, upwards, or downwards.
Innovation Solution
An auditory sensitivity adjustment device that includes a pinna holding unit, a pinna pulling unit to extend the pinna, and a pinna moving unit to twist or swing the pinna, allowing for enhanced sound perception from any direction by adjusting the pinna's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sound collection is enhanced by reverberating sound through side shield plates or ear covers, then auditory sensitivity for sound from the front is improved, but auditory sensitivity for sound from other directions (rear, sides, upward, downward) cannot be enhanced
Solution Approach 1:
The invention makes the pinna movable through a driving mechanism that can change its orientation dynamically. The pinna holding unit holds the pinna, while the pinna moving unit changes the orientation of the pinna based on the detected sound source direction, enabling the auditory system to adapt to sounds from any direction rather than being fixed for front-only detection
Solution Approach 2:
The invention extends sound detection from a single direction (front) to three-dimensional space by actively orienting the pinna toward sound sources. The pinna moving unit rotates or tilts the pinna in multiple dimensions to track sound sources regardless of their spatial location, adding directional adaptability across all spatial dimensions
2Device complexity
If the pinna is held in a fixed position, then the device structure is simple, but auditory sensitivity for sound from any direction cannot be enhanced
Solution Approach 1:
The invention introduces a dynamic pinna positioning system with a pinna holding unit that can actively adjust the pinna's orientation. This dynamic mechanism, while adding complexity, enables the system to enhance auditory sensitivity for sounds from any direction by orienting the pinna toward the sound source, resolving the trade-off between structural simplicity and functional versatility
Solution Approach 2:
The pinna moving unit operates autonomously based on sound source detection, automatically adjusting the pinna's orientation without requiring manual intervention. This self-adjusting mechanism enhances auditory sensitivity dynamically while minimizing the need for complex control systems or user interaction
