Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjusting a multi-speaker system is burdensome for users, as they need to carefully place microphones and manage noise, especially when setting up portable speakers, which requires repeated installation and can be time-consuming.
Innovation Solution
A speaker location identifying system that uses a camera to acquire images, an image recognition unit to identify speakers, a location unit to specify their positions, and a parameter decision unit to adjust audio signal parameters based on the speaker positions, reducing user burden by automating the sound output adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user manually adjusts speaker positions using a microphone, then audio signal parameters can be optimized, but the user burden and adjustment time increase significantly
Solution Approach 1:
The system enables automatic speaker position identification and audio parameter optimization without requiring manual user intervention. The image recognition unit automatically detects speaker positions, and the parameter decision unit automatically adjusts audio signal parameters based on the detected positions, making the system self-configuring and eliminating the need for users to manually place microphones or adjust settings.
Solution Approach 2:
The patent replaces the mechanical/manual process of microphone placement and physical adjustment with an automated image recognition system. Instead of using a microphone to physically detect speaker positions, the system uses a camera to capture images and an image recognition unit to automatically identify speaker locations, substituting mechanical measurement methods with optical detection and computational analysis.
2Manufacturing precision
If a user carefully places a microphone at the listener position to adjust sound, then audio quality can be optimized, but the adjustment process becomes time-consuming and complex
Solution Approach 1:
The system performs preliminary action by automatically capturing images of speaker positions before audio parameter adjustment is needed. The image recognition unit pre-identifies speaker locations and the parameter decision unit pre-determines optimal audio signal parameters based on these positions, so that when audio adjustment is required, the system already has the necessary spatial information and can quickly apply the optimal parameters without time-consuming manual measurement.
Solution Approach 2:
The patent replaces the time-consuming mechanical process of manual microphone placement and physical measurement with automated image capture and computational image recognition. The camera quickly captures the spatial arrangement, and the image recognition unit automatically processes the images to determine speaker positions, eliminating the need for users to manually measure and record positions, thereby significantly reducing adjustment time while maintaining precision.
3Reliability
If multiple speakers are arranged in a multi-channel system, then sound quality improves, but the complexity of adjusting and configuring the system increases
Solution Approach 1:
The system achieves universality by using a single integrated approach that works for any number of speakers in a multi-channel configuration. The image recognition unit can identify multiple speakers regardless of their arrangement, and the parameter decision unit can automatically determine optimal audio signal parameters for each speaker based on its detected position. This universal method eliminates the need for different configuration procedures for different speaker arrangements, simplifying the overall system complexity while maintaining high sound quality.
Solution Approach 2:
The system enables self-service configuration for multi-speaker setups by automatically detecting the positions of all speakers in the arrangement and autonomously determining the optimal audio signal parameters for each one. This self-configuring capability eliminates the need for users to manually configure each speaker individually, thereby reducing the perceived complexity of setting up multi-channel sound systems while preserving the high sound quality that multiple speakers provide.

AI summary
A speaker location identifying system includes a camera which acquires a photographed image. The speaker location identifying system recognizes an image of a speaker included in the photographed image, specifies a position of the speaker, based on a position and size in the photographed image of the recognized speaker, and decides a parameter of an audio signal outputted to the speaker, based on the specified position of the speaker.
