By setting the switch button 5, it is convenient for a user to turn on and off the rotating motor 17, thereby facilitating the use of the user.

[0026] The two earphone bodies 3 are fixedly connected to the side surfaces close to each other with earmuff rings 7, and the two earmuff rings 7 are provided with four air outlet holes 8 on the side surfaces close to each other. The upper surface of each fixing block 2 is fixedly connected to a connecting block 4, and the outer surface of each connecting block 4 is slidably connected to the inner wall of the arc-shaped elastic arm 1. By providing the connecting block 4, the user can increase the height of the earphone as needed, thereby facilitating the user to adjust to a comfortable usage position.

[0027] The two earphone bodies 3 are each provided with an air inlet hole 15 on one side away from each other, and the inner wall of each air inlet hole 15 is fixedly connected to a dust cover 6, and the two fixing plates 14 are each fixedly connected to a main board 10 on one side away from each other. By setting the dust cover 6, dust in the air can be prevented from entering the interior of the earphone body 3 when the user's ears are cooled. By setting the main board 10, a good circuit control system can be provided for the ENC noise reduction module 12, the Bluetooth module 13 and the controller 11, thereby facilitating the adjustment of the auxiliary earphone body 3.

[0028] The inner wall of each earphone body 3 is fixedly connected with a fixing plate 14, and six guide holes 16 are opened on the left side of each fixing plate 14. A controller 11 is fixedly installed on the side of the two main boards 10 away from each other, and each controller 11 is electrically connected to the main board 10 through a wire. By setting up the controller 11, it is possible to easily control the ENC noise reduction module 12 to work, thereby improving the noise reduction efficiency of the device.

[0029] The inner wall of each earphone body 3 is fixedly connected to a fixed cover 9, and the inner wall of each fixed cover 9 is fixedly connected to four rotating motors 17. An ENC noise reduction module 12 is fixedly installed on the side of the two main boards 10 away from each other. Each ENC noise reduction module 12 is electrically connected to the main board 10 through a wire. By setting the ENC noise reduction module 12, noise in the environment can be identified and eliminated, thereby improving the user experience of using the earphone body 3.

[0030] The output end of the power of each rotating motor 17 is fixedly connected to a rotating shaft 19, and the end of each rotating shaft 19 away from the rotating motor 17 is rotatably connected to the inner wall of the fixed cover 9. A Bluetooth module 13 is fixedly installed on the side of the two main boards 10 away from each other, and each Bluetooth module 13 is electrically connected to the main board 10 through a wire. By setting up the Bluetooth module 13, Bluetooth technology can be used to enable the device to perform high-speed and stable wireless data transmission within a short distance.

By providing the bearings 20, the stability of the rotating shaft 19 can be increased during rotation, avoiding shaking during use.

[0032] The working principle of the utility model is: first, the user brings the device to a suitable use position, then turns on the power of the switch button 5, the rotating motor 17, the main board 10, the controller 11, the ENC noise reduction module 12 and the Bluetooth module 13, so that they can be in a stable power-on state to avoid power outages during use, and then the user turns on the headset body 3, and connects it to the device through the Bluetooth module 13, and then wears it on the user's head for use. When the user uses the device to make a call, if the temperature of the ear is too high, the user presses the switch button 5 on the surface of the headset body 3, and the switch button 5 is pressed to control the rotation to be turned on. The rotating motor 17 starts to generate power rotation after being turned on. The rotation of the rotating motor 17 can drive the rotating shaft 19 to rotate, so that under the action of the rotation of the rotating shaft 19, the fan blades 18 on the surface of the rotating shaft 19 will be driven to rotate, and then under the action of the rotation of the fan blades 18, the air will enter the earphone body 3 from the air inlet 15, and be transmitted through the guide hole 16, and finally blow to the user's ear through the air outlet 8, thereby reducing the sealing when the user uses it, reducing the temperature of the user's ear, effectively avoiding the situation where the user's ear temperature is too high when wearing the earphone, improving the air circulation of the user's ear, and enhancing the user experience.
