Abstract: The invention aims to disclose a multi-unit wireless Bluetooth earphone structure. The earphone comprises at least one earphone cavity, wherein a Bluetooth circuit board is arranged in the earphone cavity, an electronic frequency divider is integrated on the Bluetooth circuit board, the output end of the electronic frequency divider is connected with a sounding unit, the Bluetooth circuit board isconnected with and attached with a battery unit, and the output end of the sounding unit is provided with a sound guide tube unit formed through 3D printing. Compared with the prior art, the internalstructure of the wireless Bluetooth headset is optimized, miniaturization of complex functions of the multi-unit headset is achieved, audio distortion caused by the Bluetooth transmission process iscompensated for the sounding unit and the sound guide tube unit through the multi-unit multi-guide tube technology, the tone quality of the Bluetooth headset is improved, and the purpose of the invention is achieved.
