Speaker System Automatic Channel Setting via Position Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users unfamiliar with surround audio systems face difficulties in correctly setting channels for multiple speakers, often leading to incorrect settings due to misunderstandings of speaker layout and wiring complexities.
Innovation Solution
A signal processing device with a relative-position recognition unit that identifies two reference speakers and acquires distance information to automatically set channels based on the recognized relative-position relationship between speakers, simplifying the channel setting process and ensuring accurate audio output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual channel setting is performed by connecting speakers with marks and following ideal layout instructions, then channel setting accuracy can be improved, but the ease of operation deteriorates due to complex wiring and layout requirements
Solution Approach 1:
The system automatically identifies speaker positions and assigns channels without user intervention. The master unit autonomously detects the relative positions of speakers and performs channel setting automatically, eliminating the need for users to manually arrange speakers according to marks or connect multiple wiring lines.
Solution Approach 2:
The patent replaces the mechanical/wiring-based channel setting method with an automatic detection and identification system. Instead of using physical marks and manual wiring connections, the system uses automatic position detection and electronic identification to determine speaker channels.
2Ease of operation
If automatic channel setting is implemented without manual intervention, then ease of operation is improved, but the reliability deteriorates due to potential incorrect automatic identification
Solution Approach 1:
The system provides feedback to users during the automatic channel setting process. The master unit notifies users of the detected speaker positions and assigned channels, allowing users to verify the automatic identification results and make corrections if necessary, thereby ensuring both ease of operation and reliability.
3Manufacturing precision
If detailed speaker layout instructions and marks are provided, then manufacturing precision is improved, but the device complexity increases due to additional components and setup requirements
Solution Approach 1:
The patent extracts and eliminates the need for physical marks, detailed layout instructions, and complex wiring from the system. The automatic detection system determines speaker positions and channels without requiring these additional components, thereby reducing device complexity while maintaining or improving placement accuracy.

AI summary
To enable channel setting to be performed easily and accurately to speakers. Thus, provided is a speaker system including: N number of speakers, the N being three or more; and a signal processing device capable of communicating with each speaker. The signal processing device performs processing of recognizing two arrangement reference speakers with reception of notification that a designation operation has been received from a user, from two speakers among the N number of speakers, and processing of acquiring distance information between each speaker. The signal processing device recognizes a relative-position relationship between the N number of speakers, with the two arrangement reference speakers and the distance information between each speaker. Then, the signal processing device automatically sets a channel to each speaker, on the basis of the relative-position relationship recognized.
