Mobile Conference Audio Broadcasting for Audience Q&A Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microphone systems in large venues are cumbersome, disruptive, and often ineffective, leading to audience disruption and difficulty in hearing questions in conferences and meetings.
Innovation Solution
Utilizing personal mobile communication devices, such as smartphones, to transmit audio and data signals through wireless networks or Wi-Fi to a central communication point, which then broadcasts the information to the audience via a public address system, with a moderator controlling the queue and display of questions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional microphones are moved through the audience to capture questions, then question collection is possible, but audience disruption and loss of control increase
Solution Approach 1:
The patent replaces the mechanical system of physically moving microphones through the audience with an electronic system using wireless audio transmission. Audience members use personal mobile devices to transmit audio signals wirelessly to the central communication point, eliminating the need for physical microphone movement and thereby reducing audience disruption while maintaining question collection capability
Solution Approach 2:
The patent introduces personal mobile communication devices as intermediaries between the audience members and the central communication point. These devices serve as mediators that capture and transmit audio signals wirelessly, allowing question submission without requiring physical microphone access or movement through the audience space
2Ease of operation
If microphones are placed in aisles for easy access, then question access is improved, but seating arrangement constraints increase
Solution Approach 1:
The patent replaces the mechanical constraint of physical microphone placement in specific locations with wireless audio transmission technology. Audience members can submit questions from any seating position using their personal mobile devices, eliminating the need for aisle-based microphone access points and thereby restoring full seating arrangement flexibility while maintaining easy question access
3Adaptability or versatility
If portable microphones are used for question capture, then mobile question collection is enabled, but device complexity and operational difficulty increase
Solution Approach 1:
The patent leverages the universality of personal mobile communication devices that audience members already possess. These multi-functional devices serve both as communication tools and as audio capture devices for question submission, eliminating the need for specialized portable microphones and thereby reducing device complexity while maintaining mobile question collection capability
Solution Approach 2:
The patent enables audience members to use their own personal mobile devices for question submission without requiring specialized equipment or complex operational procedures. The system is designed to work with existing consumer devices through simple wireless connection protocols, allowing self-service question capture without increasing operational difficulty
4Ease of operation
If microphones are waved or placed far from the speaker's mouth, then speaker mobility is maintained, but audio quality deteriorates
Solution Approach 1:
The patent replaces the mechanical proximity requirement between microphone and speaker's mouth with wireless audio capture technology. Personal mobile devices capture audio signals wirelessly from the speaker's mouth without requiring physical proximity or stable positioning, thereby maintaining speaker mobility while ensuring consistent audio quality through the device's built-in microphone capabilities

AI summary
A hybrid in-person and remote audiovisual conference broadcasting system provides a centrally controlled system for managing and broadcasting the audiovisual data collected from mobile devices both in humanly perceptible proximity of an in-person public-address system and beyond humanly perceptible proximity to the in-person public-address system. In an exemplary embodiment, a moderator controls requests from various participant members to broadcast audio or video from their personal mobile device to the other group members. Some members may be in proximity to an in-person public address system where they may for example be able to hear amplified audio and see live projected or otherwise presented video. In this exemplary embodiment, remote users not in proximity to the in-person public address system may also participate by for example listening to and viewing the broadcast audiovisual data on their personal mobile devices. Both in-person/local users and remote users may request to be selected for broadcasting to all users.
