Wireless Earphone Charging Case Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless earphones cannot be used to listen to music or view content during charging, as they must be disconnected from the charging case to receive power, limiting user experience and battery usage time.
Innovation Solution
A wireless earphone system that allows sound signals to be output to a speaker in the charging case, enabling music listening or content viewing during charging, with a charging case equipped with its own battery to extend usage time and reduce terminal requirements for connection and detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If wireless earphones are connected to the charging case for charging, then the batteries are charged with power, but the user cannot listen to music or view content during charging
Solution Approach 1:
The charging case is designed to perform multiple functions: it serves as both a charging device for the wireless earphones and as an audio playback device with its own speaker. When the earphones are connected to the case, the case can receive audio signals from a mobile device and output them through its speaker, allowing the user to continue listening to music or viewing content during the charging process.
2Reliability
If multiple terminals are provided for electrical connection and detection, then connectivity and detection are ensured, but the device complexity increases
Solution Approach 1:
The connection terminals are designed to perform multiple functions simultaneously. The same terminals used for electrical connection during charging also serve for connection detection. By making the terminals multi-functional, the patent reduces the total number of terminals required while ensuring both reliable connectivity and accurate detection of the charging state.
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 continuous music listening or content viewing during charging, maximizes battery usage time by charging the earphones and case efficiently, and reduces the number of terminals needed for connection and detection, enhancing user convenience and manufacturing efficiency.
Implementation Method 1
at least one of the connection terminals may be made of a conductive magnetic material, and may be magnetically connectable to a magnet provided in the charging case

AI summary
Disclosed herein is a wireless earphone system. The wireless earphone system includes wireless earphones and a charging case. Each of the wireless earphones includes: a connection unit configured to electrically connect with a charging case; and an internal circuit unit configured to receive a mode switching signal, directing a voice output mode to be switched, applied from the charging case via the connection unit, and to output a sound signal, wirelessly received from an electronic device, to the charging case via the connection unit without outputting the sound signal to a corresponding speaker by itself.
