Wireless Mobile Device Microphone Integration for Conference Audio Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing public address systems in large conference or auditorium settings are inefficient as audience members have to wait for a wireless microphone to be passed manually, introducing time delays and risks of being overlooked by the moderator.
Innovation Solution
A public address system utilizing wireless mobile communication devices as microphones, where participants can request to speak via their devices, which communicate with a back-end system to authorize and enable voice transmission to loudspeakers using cellular networks and protocols like Bluetooth or Wi-Fi, eliminating the need for manual microphone passing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wireless microphone passing is used, then audience members can speak, but time delays and missed opportunities occur
Solution Approach 1:
The system enables audience members to independently initiate speaking by simply raising their mobile devices, eliminating dependency on manual microphone distribution. The device automatically detects when the user wishes to speak and initiates the communication process without requiring assistance from conference assistants or moderators.
Solution Approach 2:
The patent replaces the mechanical manual microphone passing system with a wireless communication system using mobile devices. Instead of physically transferring a microphone, the system uses wireless signals transmitted through the mobile device's microphone to capture and transmit audio to the public address system.
2Ease of operation
If manual wireless microphone passing is used, then audience members can speak, but the moderator may accidentally overlook the audience member
Solution Approach 1:
The system provides immediate visual feedback to both the audience member and moderator through the display showing the speaker indicator. When an audience member raises their device, the display immediately shows their name and a speaker indicator, providing reliable confirmation that their request has been registered and is being processed, eliminating the risk of being overlooked.
Solution Approach 2:
The patent replaces the mechanical hand-raising and visual search system with an electronic detection system. The mobile device automatically detects when the user wishes to speak and transmits this information wirelessly to the public address system, providing reliable and immediate recognition without depending on the moderator's visual attention.
3Productivity
If mobile devices are used as microphones, then immediate access to speak is achieved, but device complexity increases
Solution Approach 1:
The patent leverages the existing multi-functional capabilities of mobile devices, which already have microphones, displays, and wireless communication abilities. Instead of adding new hardware, the system utilizes these pre-existing functions to achieve immediate speaking access, thereby avoiding the complexity of dedicated hardware while maintaining high productivity.
Solution Approach 2:
The patent introduces a communication protocol and software interface as intermediaries between the mobile device and the public address system. This intermediary layer manages the complexity of coordinating between different systems, handling the communication protocols, and ensuring proper integration without requiring the audience members to directly manage complex technical connections.
