TWS Earphone Synchronous Data Reception and Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
True Wireless Stereo (TWS) earphones face high power consumption in the master earphone and asynchronous data reception issues between the master and slave earphones when communicating with intelligent equipment.
Innovation Solution
The earphones synchronously monitor data from an intelligent terminal in a preset time sequence and perform feedback processing by sending specific response signals based on data receiving conditions, ensuring that only one response signal is received by the terminal, thereby improving data transmission performance and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the master earphone forwards data from the intelligent terminal to the slave earphone, then the slave earphone can receive data, but the master earphone power consumption increases
Solution Approach 1:
The patent divides the data reception function into two independent paths: the intelligent terminal directly transmits data packets to both the master earphone and slave earphone simultaneously. This segmentation eliminates the need for the master earphone to act as a data forwarding relay, thereby reducing its processing burden and power consumption while ensuring both earphones receive data synchronously.
2Productivity
If both earphones send response signals simultaneously when receiving data, then feedback is provided, but signal interference occurs and response accuracy decreases
Solution Approach 1:
The patent inverts the traditional feedback mechanism by having the earphone that successfully receives data send a response signal, while the other earphone suppresses its response signal. This inversion prevents signal interference and ensures the intelligent terminal receives a clear, accurate response, thereby maintaining high response accuracy while preserving feedback processing efficiency.
3Use of energy by moving object
If the master earphone monitors data in the prior art, then data can be forwarded to slave earphone, but data transmission synchronization between earphones is poor
Solution Approach 1:
The patent applies preliminary action by having the intelligent terminal prepare and transmit separate data packets to both earphones in advance, rather than having the master earphone monitor and forward data sequentially. This ensures both earphones receive data simultaneously and synchronously, improving reliability while reducing the master earphone's power consumption as it no longer needs to actively monitor and forward data.

AI summary
A communication method for earphones which include a first earphone and a second earphone includes: the first earphone and the second earphone synchronously monitoring data sent from an intelligent terminal in a preset time sequence and performing feedback processing according to a data receiving condition; the first earphone sending out a first response signal if receiving the data; or the first earphone sending no response signal if not receiving the data; and the second earphone sending no response signal if receiving the data or the second earphone sending a second response signal if not receiving the data. By implementing embodiments of the present disclosure, the two earphones can synchronously receive data sent from the intelligent terminal, so that the communication reliability is improved. In addition, the two earphones give responses in different manners, so that power consumption of the earphones is reduced.
