RFID Speaker Grouping Control for Sound Bars and Wireless Speakers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grouping technologies for sound bars and wireless speakers require cumbersome manual settings for frequent addition to and removal from groups, making it difficult to move wireless speakers between rooms and maintain a high-quality surround sound experience.
Innovation Solution
Implementing RFID tags on controllers and sound bars/wireless speakers for automatic group formation and disbanding through simple user operations, such as touching the controller to the device, allowing seamless addition or removal from groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual settings are used for addition to and removal from group, then grouping function can be achieved, but operation becomes cumbersome and time-consuming
Solution Approach 1:
The system performs automatic group formation and disbanding operations without requiring manual user input. When a wireless speaker is powered on or a controller is brought near, the system automatically detects the presence, checks group status, and executes joining or disbanding operations autonomously, eliminating the need for users to manually configure settings each time.
Solution Approach 2:
The system stores information about the last joined group in advance. When a wireless speaker is powered on or a controller approaches, the system retrieves this stored information and automatically re-joins the previously joined group, eliminating the need for users to reconfigure settings and enabling seamless transitions between rooms.
2Adaptability or versatility
If wireless speaker is moved to another room and used alone, then mobility is improved, but group configuration becomes complex
Solution Approach 1:
The system dynamically adapts its group configuration based on real-time conditions. When a wireless speaker is moved to another room, the system automatically detects the change in environment and adjusts the group configuration accordingly - either disbanding the group if used alone or automatically re-joining if a controller is present, enabling seamless mobility without complex manual reconfiguration.
Solution Approach 2:
The system continuously monitors its operational environment through controllers and power state detection. When a wireless speaker is moved to another room, the system receives feedback about the new environment (presence of controllers, power status) and automatically adjusts group configuration based on this feedback, simplifying the adaptation process.
3Ease of operation
If automatic group management is implemented, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The patent replaces complex manual mechanical configuration operations with automated electronic detection and control systems. RFID tags and readers automatically detect device presence and exchange information electronically, substituting manual button presses and settings adjustments with automated electronic identification and group management protocols.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and user-friendly grouping and disbanding of sound bars and wireless speakers, maintaining high-quality surround sound playback with automatic group management.
Implementation Method 1
an RFID tag reader is provided in the sound bar. When a user brings the controller close to the sound bar, the sound bar reads the tag information out of the RFID tag of the controller with the RFID tag reader

AI summary
[Problem] To enable a sound bar and a wireless speaker to be grouped and ungrouped through a simple operation. [Solution] When a user moves a controller 3 closer to a sound bar 1, the sound bar 1 reads tag information from an RFID tag 30 of the controller 3 by using an RFID tag reader 10, detects that the user has performed an operation to move the controller 3 closer to the sound bar 1, and checks a host group state. When group formation is in progress, an ungroup notification is transmitted to a wireless speaker 2, which is a participating member of the group, to ungroup the group, and information relating to a slave of the ungrouped group is stored as immediately preceding slave information. However, when ungrouping is in progress, a group formation notification is transmitted to the wireless speaker 2 identified by the immediately preceding slave information to form a group with the wireless speaker 2.
