[0034] Please refer to Figures 1 to 6 The embodiment provides a video conference all-in-one machine integrating an array microphone and a camera, which comprises an all-in-one machine body 1, a main camera 101 and a plurality of array distributed microphones 102 are arranged on the front face of the all-in-one machine body 1, a front-rear telescopic mechanism 103, a left-right rotating mechanism 104 and a control mainboard 105 are arranged in the all-in-one machine body 1, the control mainboard 105 is electrically connected with the main camera 101, the plurality of microphones 102, the front-rear telescopic mechanism 103 and the left-right rotating mechanism 104 respectively, the main camera 101 is fixed on the telescopic end of the front-rear telescopic mechanism 103, and the front-rear telescopic mechanism 103 is fixed on the rotating end of the left-right rotating mechanism 104.

[0035] The array distributed microphones 102 are used for collecting nearby sound and performing sound source positioning, so that the main camera 101 performs sound source tracking and center focusing, and the video call effect in the conference and user experience are improved.

[0036] The front-rear telescopic mechanism 103 is used for driving the main camera 101 to stretch out of the all-in-one machine body 1 or retract into the all-in-one machine body 1, wherein after the all-in-one machine body 1 is started, the front-rear telescopic mechanism 103 drives the main camera 101 to stretch out of the all-in-one machine body 1, so that the left-right rotating range of the main camera 101 reaches the maximum; after the all-in-one machine body 1 is turned off, the front-rear telescopic mechanism 103 drives the main camera 101 to retract into the all-in-one machine body 1, which not only can effectively protect the main camera 101 from external damage, but also increases the overall aesthetic degree.

[0037] The left-right rotating mechanism 104 is used to drive the main camera 101 to rotate left and right, so that the main camera 101 can rotate freely in the horizontal direction, thereby greatly expanding the shooting range and enabling the all-in-one machine to capture a wider conference scene. By receiving the sound source positioning information transmitted by the control mainboard 105, the left-right rotating mechanism 104 can drive the main camera 101 to rotate left and right, ensuring that the main camera 101 can accurately aim at the position of the current speaker and realize the sound source tracking function.

[0038] Please refer to Figure 4 , Figure 5 In an embodiment, the front-rear telescopic mechanism 103 includes a telescopic cylinder 1031 and a front-rear telescopic rod 1032, and the main camera 101 is fixed to the telescopic ends of the telescopic cylinder 1031 and the front-rear telescopic rod 1032, respectively. The telescopic cylinder 1031 and the front-rear telescopic rod 1032 are fixed to the rotating end of the left-right rotating mechanism 104. The telescopic cylinder 1031 serves as a driving source and provides the power required for the front-rear telescopic movement of the main camera 101. Through the telescopic action of the telescopic cylinder 1031, the main camera 101 can be accurately driven to extend forward out of the all-in-one machine body 1 or to retract backward into the all-in-one machine body 1. The front-rear telescopic rod 1032 serves to transmit the power of the telescopic cylinder 1031 and guide the front-rear movement of the main camera 101, ensuring that the main camera 101 does not shake or deviate during the telescopic movement. Of course, in other embodiments, other front-rear telescopic mechanisms 103 can be used to drive the main camera 101 to extend forward out of the all-in-one machine body 1 or to retract backward into the all-in-one machine body 1, and the present application does not limit this.

[0039] Please refer to Figure 4 , Figure 5 In an embodiment, the left-right rotating mechanism 104 includes a rotating motor 1041 and a gear transmission assembly 1042, and the rotating shaft of the rotating motor 1041 is connected to the front-rear telescopic mechanism 103 through the gear transmission assembly 1042 to drive the front-rear telescopic mechanism 103 and the main camera 101 to rotate left and right. The rotating motor 1041 serves as a power source of the left-right rotating mechanism 104 and provides the power required for driving the front-rear telescopic mechanism 103 and the main camera 101 to rotate left and right. By controlling the rotation speed and direction of the rotating motor 1041, the rotation angle and speed of the main camera 101 can be accurately adjusted. The gear transmission assembly 1042 serves to transmit the rotating power and guide the left-right rotation of the front-rear telescopic mechanism 103 (and the main camera 101 thereon), to ensure the accuracy and reliability of the rotating action. Of course, in other embodiments, other left-right rotating mechanisms 104 can be used to drive the main camera 101 to rotate left and right, and the present application does not limit this.

[0040] Please refer to Figure 1 , Figure 2 , Figure 6In an embodiment, the front of the all-in-one machine body 1 is also provided with a secondary camera 106, which is electrically connected to the control mainboard 105. The secondary camera 106 is a wide-angle camera, which has a wider field of view and can capture more details of the conference scene. In a video conference, the primary camera 101 is used to track the position of the current speaker and focus on shooting. The secondary camera 106 can capture a wider conference scene by using its wide-angle feature. When it is necessary to show the layout of the entire conference room or capture the images of multiple participants, the wide-angle shooting mode of the secondary camera 106 can be switched on. When it is necessary to focus on a specific speaker, the primary camera 101 can be switched back on for shooting.

[0041] Please refer to Figure 1 , Figure 2 , Figure 6 In an embodiment, the front of the all-in-one machine body 1 is also provided with a laser ranging head 107, which is electrically connected to the control mainboard 105. The laser ranging head 107 measures the distance from the all-in-one machine body 1 to the speaker by emitting a laser beam and receiving the reflected signal. Since the laser ranging head 107 is electrically connected to the control mainboard 105, it can transmit the measurement results to the control mainboard 105 in real time for processing. Based on the measurement results of the laser ranging head 107, the control mainboard 105 can calculate the specific position of the speaker and instruct the primary camera 101 to quickly center and focus. The setting of the laser ranging head 107 not only improves the accuracy and speed of the focusing of the primary camera 101, but also enables the primary camera 101 to more accurately track the position of the speaker, thereby improving the overall effect of the video conference.
