Wireless Headset Audio Relay via Bluetooth Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless headset systems require users to disconnect and reconnect to share audio signals, which is cumbersome and inconvenient, especially when the involved audio source does not support multiple connections.
Innovation Solution
A device and method that enables wireless transmission of audio signals and signaling messages between headsets, allowing users to invite others to listen to the same audio signal by acting as an alternative audio source, using technologies like Bluetooth for seamless connection switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user wants to share audio signal with another person using known art, then the invited person must disconnect from current audio source and connect to the same audio source, but this operation is cumbersome and annoying
Solution Approach 1:
The first headset acts as an intermediary device between the audio source and the second headset. It receives the audio signal from the audio source and relays it to the second headset, eliminating the need for the second headset to directly connect to the audio source and avoiding disconnection operations.
Solution Approach 2:
The first headset creates a copy of the audio signal it receives from the audio source and transmits this copied signal to the second headset. This allows the second headset to receive the same audio content without establishing a direct connection to the original audio source.
2Adaptability or versatility
If the audio source does not support multiple wireless connections, then the inviting person must disconnect from the audio source to allow the invited person to connect, but this disrupts the inviting person's audio listening
Solution Approach 1:
The first headset serves as a mediator that maintains the connection to the audio source while simultaneously providing audio output to the second headset. This intermediary role allows the audio source to maintain a single connection while still enabling multiple listeners.
Solution Approach 2:
The audio signal path is segmented into two separate transmission paths: one from the audio source to the first headset, and another from the first headset to the second headset. This segmentation allows the first headset to act as an independent relay node.
3Device complexity
If manual disconnection and reconnection is required to share audio, then the process becomes cumbersome, but the system maintains simple connection management
Solution Approach 1:
The first headset as an intermediary automatically manages the audio signal relay between the audio source and second headset, eliminating the need for manual disconnection and reconnection operations while maintaining straightforward connection management.

AI summary
An audio reproduction device, a system, and a method for allowing a first user, who is listening to a first audio signal though a first headset, is provided to invite a second user, who is listening to a second audio signal through a second headset, to quickly start listening to the first audio signal. To this purpose, the first headset sends a signalling message to the second headset and relays the first audio signal to it. Both the audio signals emitted by the audio sources and that relayed by the first headset may be transmitted by means of a Bluetooth technology enabling a device both to receive a Bluetooth signal as a slave in a piconet and to transmit a corresponding Bluetooth signal as a master in another piconet.
