Split Wireless Earphone Battery Module for Fast Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The batteries in existing wireless earphones are non-replaceable, leading to short battery life and the need for time-consuming charging through a charging case.
Innovation Solution
A wireless earphone design that splits into two bodies, where one body includes the battery, allowing for magnetic attraction and repulsion to disconnect and reconnect for charging or replacement, eliminating the need to charge the entire earphone at once.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wireless earphone uses a non-removable battery with compact positioning, then the earphone structure is compact and integrated, but the battery life is short and cannot be replaced when power is low
Solution Approach 1:
The wireless earphone is divided into two separable bodies: a first body containing the sound output component and a second body containing the battery. This segmentation allows the battery to be independently replaced or recharged without replacing the entire earphone, resolving the contradiction between integrated structure and extendable battery life.
2Device complexity
If the battery is non-removable, then the earphone structure is simplified, but charging requires the entire earphone to be placed in a charging case which is time-consuming
Solution Approach 1:
By separating the battery into an independent second body, the charging process can be optimized. The second body can be quickly detached and recharged separately or replaced with a pre-charged battery, significantly reducing the time loss associated with charging the entire earphone unit.
Solution Approach 2:
The second body containing the battery can be pre-charged independently before being attached to the first body. This preliminary charging action allows the user to have a ready-to-use battery module, eliminating the need to wait for the entire earphone to charge during usage.
3Reliability
If the battery is non-removable, then the earphone maintains continuous power supply, but when power is low the only option is to use the charging case which is inconvenient
Solution Approach 1:
The separable battery design maintains power supply reliability by ensuring the second body remains connected to the first body during use, while enabling convenient operation by allowing the battery to be quickly detached and replaced or recharged without requiring the entire earphone to be placed in a charging case.
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 convenient battery replacement or charging by allowing the battery-containing body to be removed and charged separately, extending battery life and reducing charging time.
Implementation Method 1
the first magnetic member and the second magnetic member have opposite polarities attracting each other
Implementation Method 2
the first magnetic member and the second magnetic member have a same polarity repelling each other

AI summary
Embodiments of this application provide a wireless earphone, a wireless earphone box, and a wireless earphone device. The wireless earphone includes a first body and a second body. A first end face of the first body is provided with a first magnetic member. A second end face of the second body is provided with a second magnetic member. An outer surface of the second body is provided with a third contact. The second body includes a first battery. The third contact is energized to cause the first body and the second body to be in a connected state or separated state.
