Bluetooth Audio Playback Group Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as Wi-Fi, are not available in all areas, making it difficult for multiple audio playing devices to play music simultaneously without a stable network connection.
Innovation Solution
An audio playing method and apparatus that uses Bluetooth connections to establish a private network among devices, allowing an audio source device to connect with any playing device and forward audio data to other devices within the network, enabling simultaneous music playback even without Wi-Fi, while minimizing Bluetooth interference by turning off Bluetooth functions on other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Wi-Fi is used to connect multiple playing devices and a control terminal to enable simultaneous music playback, then simultaneous audio playback across multiple devices is achieved, but the system becomes unavailable in areas where Wi-Fi is not accessible
Solution Approach 1:
The patent makes the audio playback system universally applicable by replacing Wi-Fi dependency with Bluetooth connectivity. The control terminal can establish Bluetooth connections with multiple playing devices directly, enabling simultaneous audio playback in both Wi-Fi available and Wi-Fi unavailable environments. This multi-functionality approach allows the system to operate across different network infrastructures.
Solution Approach 2:
The patent changes the communication parameter from Wi-Fi (wireless LAN) to Bluetooth (short-range wireless personal area network). By altering the fundamental communication protocol parameter, the system adapts to environments where Wi-Fi is unavailable while maintaining the core functionality of simultaneous multi-device audio playback.
2Adaptability or versatility
If Bluetooth connection is established between audio source device and playing devices for audio data transmission, then Wi-Fi availability is no longer required, but Bluetooth interference and power consumption increase
Solution Approach 1:
The patent implements dynamic Bluetooth connection management where the control terminal actively establishes Bluetooth connections only with playing devices that need to receive audio data. The system dynamically creates and manages Bluetooth connections based on real-time playback requirements, establishing connections temporarily during audio transmission and managing their lifecycle to optimize power consumption.
Solution Approach 2:
The patent extracts the Bluetooth function activation from all playing devices and concentrates it only in the control terminal. By taking out the active Bluetooth connection management from individual playing devices and centralizing it in the control terminal, the system reduces overall Bluetooth interference and power consumption while maintaining the ability to distribute audio data to multiple devices.
3Ease of operation
If multiple playing devices maintain Bluetooth function enabled for potential connections, then connection flexibility is improved, but Bluetooth interference increases and power consumption rises
Solution Approach 1:
The patent implements preliminary connection establishment where the control terminal proactively establishes Bluetooth connections with all playing devices that will participate in simultaneous audio playback before initiating audio data transmission. This preliminary action ensures connection flexibility is maintained for all required devices while limiting active Bluetooth transmissions to only what is necessary, thereby reducing overall Bluetooth interference.
Solution Approach 2:
The control terminal acts as an intermediary that manages Bluetooth connections between the audio source and multiple playing devices. By serving as a central mediator, the control terminal consolidates Bluetooth communication, reducing the number of direct Bluetooth transmissions required and thereby minimizing Bluetooth interference while maintaining connection flexibility for all playing devices.

AI summary
The present disclosure relates to an audio playing method and apparatus based on Bluetooth connection. The method includes: receiving a Bluetooth connection request sent from a first audio source device by a first playing device; responding to the Bluetooth connection request by the first playing device, establishing a Bluetooth connection with the first audio source device and notifying other playing devices of a target playing group including the first playing device to close Bluetooth function by the first playing device, wherein the target playing group includes at least one playing device communicating via a private network established in advance; and receiving first audio data from the first audio source device by the first playing device based on the Bluetooth connection, and forwarding the first audio data to the other playing devices of the target playing group via the private network by the first playing device, whereby all playing devices of the target playing group will play music corresponding to the first audio data. With implementation of the present disclosure, multiple playing devices of a playing group can play audio based on Bluetooth connection.
