Wireless Headset Single-Channel Audio Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth-based wireless headsets face issues with mismatched energy consumption between earpieces and complex data transmission methods, leading to limited usage time and high complexity.
Innovation Solution
The method involves the first earpiece sending channel information about the audio transmission channel to the second earpiece, allowing both to receive audio data via one channel, reducing energy consumption and complexity by eliminating the need for independent channels and response messages from both earpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each earpiece establishes an independent Bluetooth connection with the mobile device, then both earpieces can receive audio data, but the energy consumption of the two earpieces does not match and the transmission complexity increases
Solution Approach 1:
The patent merges the Bluetooth connections by having the first earpiece establish a single connection with the mobile device and share the audio data transmission channel with the second earpiece through internal communication. This eliminates the need for two separate Bluetooth connections, thereby reducing energy consumption while ensuring both earpieces can receive audio data reliably.
Solution Approach 2:
The first earpiece acts as an intermediary between the mobile device and the second earpiece. It receives audio data from the mobile device via Bluetooth and then transmits this data to the second earpiece through an internal communication interface, enabling the second earpiece to receive audio data without establishing its own independent Bluetooth connection.
2Reliability
If each earpiece establishes an independent Bluetooth connection with the mobile device, then both earpieces can receive audio data, but the transmission complexity increases
Solution Approach 1:
The patent combines the transmission paths by using a single Bluetooth connection from the mobile device to the first earpiece, which then shares the audio data with the second earpiece internally. This reduces the number of active transmission channels from two to one, simplifying the overall transmission complexity while maintaining reliable audio data reception at both earpieces.
Solution Approach 2:
The first earpiece serves as an intermediary that simplifies the transmission architecture. Instead of the mobile device managing two separate Bluetooth connections, it only needs to maintain one connection to the first earpiece, which then handles the data distribution to the second earpiece, thereby reducing transmission complexity.
3Reliability
If two independent channels are maintained for audio transmission, then both earpieces can receive data, but the energy consumption increases and usage time is limited
Solution Approach 1:
The patent merges the transmission channels by using a single active Bluetooth channel from the mobile device to the first earpiece, which then shares this channel with the second earpiece through internal communication. This reduces the total energy consumption associated with maintaining two separate channels, thereby extending the usage time while ensuring reliable data transmission to both earpieces.

AI summary
Disclosed is a wireless headset and a signal transmission method for the same, the method comprises: sending, by a first earpiece, channel information about an audio transmission channel to a second earpiece after establishing the audio transmission channel with a mobile device; receiving, by the first earpiece, audio data from the audio transmission channel, and sending a response message to the mobile device; and receiving, by the second earpiece, audio data from the audio transmission channel according to the channel information about the audio transmission channel. The mobile device enables the two earpieces both to receive the audio data without maintaining two channels and it only requires the first earpiece to return a response message to the mobile device; and the difference between the energy consumption of the two earpieces is relatively small, and the mobile device only needs to maintain one channel, thus the complexity is relatively low.
