A vehicle-mounted Bluetooth manipulator comprises a control circuit for inputting signals by means of Bluetooth, and further comprises a rotating arm (1) and a telescopic arm (2) that are controlled by the control circuit and that are connected to each other. The telescopic arm is connected to an earphone and a microphone (22). The rotating arm (1) is provided with a positioning structure connected to a vehicle seat backrest. The vehicle-mounted Bluetooth manipulator has the following advantages: during a conversation, signals are sent by means of Bluetooth, and the microphone and the earphone are transported to the ears of a driver by the manipulator, so that the interference to the driver caused by a phone is lowered, a hand-free mode is not required, and accordingly, the privacy of call content is ensured.
