Flush Radio Audio Control via Separate Data Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio arrangements for IP-based single speakers and multiroom systems require control through mobile devices with pre-installed apps, limiting control options when these devices are not available or accessible.
Innovation Solution
An audio arrangement with a flush-mounted radio connected to speakers via separate data interfaces for audio and control data transfer, allowing control of speakers via a radio interface, such as WLAN or Bluetooth, enabling control without mobile devices, and allowing integration into building automation systems for distributed audio control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IP-based single speakers and multiroom systems are controlled via mobile devices with pre-installed apps, then the control functionality is available, but the system becomes dependent on mobile devices and applications
Solution Approach 1:
The flush-mounted radio is equipped with a control unit that can generate control signals independently without requiring mobile devices. The control unit includes input devices (push buttons, touch sensors) that allow direct local control, enabling the system to serve itself and eliminating dependency on external mobile applications.
Solution Approach 2:
The control unit in the flush-mounted radio is designed to perform multiple functions: it can control local speakers, transmit control signals to remote IP-based speakers via data interfaces, and operate independently or in conjunction with building automation systems. This multi-functionality allows the same device to replace mobile device control while maintaining compatibility with existing systems.
2Adaptability or versatility
If a flush-mounted radio is integrated into building automation systems with separate data interfaces for audio and control data, then control of distributed speakers is enabled, but the device complexity increases
Solution Approach 1:
The data communication functionality is divided into separate data interfaces: one for audio data transmission and another for control signal transmission. This segmentation allows each interface to be optimized for its specific function and enables independent configuration and troubleshooting, managing complexity through functional separation.
Solution Approach 2:
The control unit acts as an intermediary between the flush-mounted radio and IP-based speakers. It generates control signals, transmits them via data interfaces to remote speakers, and coordinates communication between different system components, simplifying the overall system architecture by providing a centralized control point.
