Further, when the feed-in unit feeds into the battery in a coupled feed-in manner, a coupling section is also provided between the feed-in unit and the battery to realize the coupling feed-in between the feed-in unit and the battery.

Further, the feed-in part is a shrapnel or a thimble, or any other feed-in connection material. The feed-in part is connected to the ground terminal of the PCB board

The present invention also provides a true wireless bluetooth earphone, which adopts the above-mentioned bluetooth earphone antenna structure, including an earphone shell, an earphone unit, a PCB board and a battery, the earphone unit is embedded in the earphone shell, and the PCB The board and the battery are arranged inside the earphone casing, and the PCB board is electrically connected to the battery. The PCB board is attached to the earphone unit, and the PCB board is arranged between the battery and the user's position, so as to prevent the electrical material or metal on the PCB board from affecting the radiation and reception of the antenna structure.

The Bluetooth headset integrates the battery into the radiation part of the antenna structure, reduces the impact of the battery on the spatial layout and radiation efficiency of the antenna structure in the true wireless Bluetooth headset, and improves the communication effect of the antenna structure. The spatial position in the earphone reduces the shielding and influence of the earphone monomer and other materials and the human body on the antenna structure, and improves the radiation and reception effect of the antenna structure.

Further, the battery is placed close to the inner side of the earphone shell, so as to avoid or reduce the impact of the human body effect on the communication effect of the antenna structure.

Further, the earphone shell is made of non-metallic material, which can be ABS material, PC material, or any other non-metallic material, so as to avoid shielding or influence of metal material on antenna signal radiation or reception.

Further, a capacitor C is also provided between the battery and the ground terminal to prevent the earphone from being damaged due to a short circuit when the battery serves as the radiating part of the antenna structure.

Compared with the prior art, the antenna structure in the present invention integrates the battery into the radiation part of the antenna structure by feeding the battery into the feed-in part, thus saving the space used by the antenna structure in the earphone and solving the problem of the antenna structure in the earphone due to space issues. Problems with limited shape that affect communication quality.
