Wireless headsets, including Bluetooth headsets, are free from the shackles of connecting wires, and because they can reduce the adverse effects of electromagnetic radiation on the brain during mobile phone calls, use hands-free calls to free hands, and gradually increase the use of 3G video calls. Gradually become a common accessory for mobile phones. However, the existing wireless earphones are designed independently, and the earphones and their chargers increase the number of independent items carried by the user, which is inconvenient to carry. The earphone battery needs to be charged independently. A large-capacity earphone battery can prolong the charging time interval, but the large size is not conducive to the lightweight design of the earphone, and the small capacity requires frequent charging. During standby, wireless communication (Bluetooth) consumes the power of information terminals such as earphones and mobile phones, and increases the risk of spreading Bluetooth viruses and leaking information. Above-mentioned various shortcomings, have become the obstacle that wireless earphone is further popularized. Incorporating wireless earphones into information terminals such as mobile phones is a good idea to solve the above problems. But in the prior art scheme, there are still many unresolved technical problems.

The earphone charging socket is a common technical feature of the existing wireless earphones. In this utility model, the utility model describes the use of contact-type insertion into the charging socket to disconnect the wireless circuit provided on the earphone, and to integrate the microphone and earpiece into the mobile phone circuit. However, this utility model does not involve the necessary technical features of using the power of the mobile phone to recharge the earphones, such as the charging control circuit, nor does it involve the beneficial effects of using the power of the mobile phone to recharge the earphones, which can further reduce the size of the earphone battery and avoid manual additional charging. technical issues.

Even with some other technical solutions, there are still many unresolved technical problems, which affect its practicability. For example: 1. The earphones are too large, which has a great impact on the design of the host circuit board and battery of the combined earphones, which is not conducive to the constant pursuit of The design of information terminals such as portable mobile phones; 2. When considering the combination design with mobile phones and other hosts, the shape of the earphones does not conform to the ergonomics of wearing in the ear, which is not conducive to stable wearing, and the appearance is not beautiful; 3.
