Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microphone systems face challenges in effectively utilizing sound information acquired from multiple devices in a group setting, particularly in suppressing noise and ensuring secure device grouping without compromising user experience.
Innovation Solution
A microphone cooperation device comprising a first device with a microphone and speaker, and a second device with a microphone and speaker, where the devices join a group by receiving a sound wave emitted from the first speaker, allowing for secure and effective information utilization through sound-based authentication and noise suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If devices are grouped using sound wave transmission, then device cooperation and information utilization are improved, but device grouping distance becomes limited
Solution Approach 1:
The patent combines multiple devices into a cooperative group through sound wave transmission, merging their microphone capabilities to achieve enhanced sound information acquisition and processing that would be impossible for individual devices
Solution Approach 2:
Sound waves serve as an intermediary medium for device authentication and grouping, enabling devices to establish cooperative relationships without direct physical connection while maintaining secure distance-limited communication
2Measurement precision
If multiple microphones are used for sound information acquisition, then sound quality and noise suppression are improved, but system complexity increases
Solution Approach 1:
The patent merges multiple microphones from different devices into a unified cooperative system, allowing the devices to function as a single multi-microphone array for enhanced sound quality and noise suppression without requiring complex centralized control
Solution Approach 2:
Each device in the cooperative group independently processes its own microphone data and contributes to the group's sound information acquisition, reducing the need for complex centralized processing while maintaining high sound quality
