Dynamic Microphone Array Orientation for Handheld Sound Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held electronic devices with fixed microphone arrays face challenges in accurately collecting sound information when the device's usage status changes, such as from vertical to horizontal screen orientation, leading to poor sound collection or failure to collect sound information.
Innovation Solution
A data processing method and electronic apparatus that allow the microphone array to adjust its usage mode and position in real-time based on the device's usage status, using a direction sensor to optimize sound collection by switching between different usage modes corresponding to the current status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the microphone array is fixed in one space, then the sound collection function is simple and stable, but the sound collection accuracy deteriorates when the usage status changes
Solution Approach 1:
The microphone array is designed to be dynamically adjustable rather than fixed. The system includes adjustment mechanisms that allow the microphone array to change its position and orientation according to the usage status of the electronic apparatus. This dynamic adjustment enables the microphone array to maintain optimal sound collection accuracy across different usage scenarios while adapting to changing conditions.
Solution Approach 2:
The system changes the parameters of the microphone array (position, orientation, usage mode) based on the usage status of the electronic apparatus. When the usage status changes, the control system adjusts the microphone array parameters accordingly to maintain optimal sound collection performance. This parameter change approach allows the system to adapt to different usage conditions without requiring a completely different microphone array configuration for each scenario.
2Adaptability or versatility
If the microphone array is fixed in one position, then the device structure is simple, but the adaptability to different usage scenarios deteriorates
Solution Approach 1:
The microphone array is designed with multi-functionality to serve different usage scenarios. It can operate in multiple usage modes (e.g., first usage mode for vertical screen, second usage mode for horizontal screen) and can be adjusted to different positions and orientations. This universal design allows a single microphone array system to adapt to various usage conditions, eliminating the need for separate microphone array configurations for each scenario.
Solution Approach 2:
The system incorporates dynamic adjustment capabilities that allow the microphone array to transition between different configurations based on usage status. The adjustment mechanism enables the microphone array to reposition and reorient itself, providing adaptability to different usage scenarios while maintaining a unified device structure.
3Area of stationary object
If the microphone array cannot change direction, then the structure is stable, but the sound collection coverage deteriorates in different orientations
Solution Approach 1:
The microphone array incorporates dynamic direction adjustment capabilities that allow it to change its orientation according to the usage status. The adjustment mechanism enables the microphone array to rotate and reposition, expanding the sound collection coverage area. This dynamic directional change allows the system to maintain optimal sound collection performance across different orientations and usage scenarios.
