As a prior art, the detailed technical content of the head-mounted first-person perspective live broadcast device has also been disclosed, such as the patent document with application number 201920327260.8, which proposes "putting the protective shell on the head of the live broadcaster, buckling the buckle rope, pulling the elastic head to tighten the buckle rope, which is conducive to the fixation of the protective shell. Through the joint action of the protective shell, the anti-collision net and the buckle rope, it is conducive to protecting the safety of the live broadcaster's head and improving the safety of the equipment; when in use, the battery in the battery box powers the equipment. During live broadcast, the LED light provides lighting for the live broadcast site. Turn the shaft knob to adjust the angle of the lighting device. The lighting device drives the camera to rotate, thereby adjusting the camera position, which is conducive to adjusting the camera angle and is convenient for live broadcast; recording through the microphone and receiving voice through headphones is conducive to the use of live broadcast equipment and the multi-functional use of live broadcast equipment."
