Loudspeaker Control via Spatial GUI and Sensory Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual configuration of identifiers for loudspeakers in a multi-loudspeaker system is slow, prone to errors, and can lead to confusion due to the potential for identical codes being assigned to different speakers, complicating messaging and control.
Innovation Solution
A control device with a graphical user interface allows for the assignment of names and audio channels to loudspeakers based on their location, using sensory signals to facilitate accurate identification and configuration, and includes features for calibration and equalization, such as phase calibration using maximal cancellation or Fourier analysis methods.

Engineering Contradiction Analysis
1Measurement precision
If manual configuration of identifiers is used for loudspeakers, then each loudspeaker can be individually identified, but the process becomes slow and error-prone
Solution Approach 1:
The system automatically assigns identifiers to loudspeakers by detecting their presence and characteristics, eliminating the need for manual configuration. The control device autonomously identifies each loudspeaker and assigns a unique identifier without user intervention, thereby reducing configuration time while maintaining accuracy.
Solution Approach 2:
The patent replaces manual mechanical identifier configuration with an automated electronic detection and assignment system. The control device uses electronic signals and processing to automatically identify and name loudspeakers, substituting the manual mechanical process of physical switch configuration with automated digital identification.
2Ease of operation
If manual identifier assignment is performed, then users can configure loudspeakers, but confusion arises from identical codes being assigned to different speakers
Solution Approach 1:
The control device continuously detects and monitors the identifiers assigned to loudspeakers, providing feedback to ensure uniqueness. The system verifies that each assigned identifier is distinct and corresponds to the correct loudspeaker, preventing duplicate assignments and resolving confusion through automated verification.
Solution Approach 2:
The patent replaces manual identifier assignment with automated electronic detection that inherently ensures uniqueness. The control device uses electronic processing to generate and assign unique identifiers based on detected loudspeaker characteristics, eliminating the human error that leads to duplicate codes.
3Adaptability or versatility
If manual configuration is used, then users can assign identifiers, but the complexity of messaging and control increases
Solution Approach 1:
The control device automatically manages identifier assignment and messaging routing, reducing the complexity burden on users. The system self-configures the communication paths and identifier mappings, allowing users to simply interact with the graphical interface without managing underlying control complexity.
Solution Approach 2:
The patent introduces a graphical user interface dimension that simplifies control complexity. Instead of dealing with direct manual configuration of multiple identifiers and messaging paths, users interact with a visual representation that automatically handles the complexity of identifier assignment and communication routing in the background.
