Mobile Device Audio Routing via Room Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio reproduction systems for conferences and lectures require a central wired microphone tied to a specific room, limiting flexibility and requiring separate transmission systems for each room, while users must manually dial in to access audio via their mobile devices.
Innovation Solution
A method where mobile devices connect to a server via a wireless local network, detect room information, and receive the corresponding audio data stream, allowing flexible audio reproduction across rooms without the need for a dedicated central microphone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a central wired microphone is used in each room, then audio transmission is reliable, but the system complexity increases and flexibility decreases
Solution Approach 1:
The patent extracts the microphone function from fixed room installations and relocates it to mobile devices. Users can speak through their own mobile devices, eliminating the need for centralized wired microphones in each room. This reduces system complexity while maintaining audio transmission reliability through the wireless network infrastructure.
Solution Approach 2:
The patent makes mobile devices universal by enabling them to serve multiple functions: they act as personal microphones, audio receivers, and network communicators. A single mobile device can be used across different rooms without requiring room-specific hardware, thereby reducing overall system complexity while ensuring reliable audio transmission through the unified network system.
2Reliability
If separate transmission systems are used for each room, then audio quality is maintained, but the device complexity and installation requirements increase
Solution Approach 1:
The patent merges separate room-specific transmission systems into a unified network-based system. All rooms share a common network infrastructure for audio transmission, eliminating the need for separate transmission systems in each room. Audio quality is maintained through the network's capabilities while system complexity is reduced by consolidation.
3Ease of operation
If manual dialing is required to access audio, then connection control is precise, but ease of operation decreases
Solution Approach 1:
The patent implements self-service by enabling mobile devices to automatically detect and connect to available audio rooms through the network. Users simply need to select their desired room from a list, and the system automatically establishes the connection without requiring manual dialing or complex setup procedures. This dramatically improves ease of operation while minimizing connection setup time.
Data Source
AI summary
A method for receiving audio data streams with mobile devices in different rooms in which sound is emitted via loudspeakers. Each mobile device connects over a local wireless network to a server that controls the sound emitted in the rooms via loudspeakers. Each mobile device detects room information, emitted only in the corresponding room, that indicates the room the respective mobile device is in. The room information is transmitted from each mobile device to the server. The server associates each room information with an output audio data stream that corresponds to the sound emitted via loudspeaker in the respective room in which the mobile device has detected the room information. The server assigns to each of the mobile devices an output audio data stream corresponding to the respective room information, and transmits the output audio data stream over the local network to the mobile device, which receives and replays it.
