[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figures 1 to 5 The utility model provides a microphone system, including a microphone body and a protective cover. The microphone body includes a base 1, a microphone adjustment rod 2 and a pickup head 3. The pickup head 3 is connected to the base 1 through the microphone adjustment rod 2. The microphone body is the existing technology. In some embodiments of the present application, the model of the microphone body may be SV-WM90A.

[0023] The protective cover is adapted to the pickup head 3 and includes a fixed plate 7 and a cover body 4. The fixed plate 7 is fixedly connected to one end of the pickup head 3 close to the microphone adjustment rod 2. A through hole is provided in the middle of the fixed plate 7, and the microphone adjustment rod is adapted to the through hole.

[0024] Fixed grooves are evenly arranged on the side walls of the fixed plate 7. A connecting rod 14 is movably connected to one side of the fixed groove. The other end of the connecting rod 14 is fixedly connected to one side of the cover body 4. The cover body 4 is movably connected to the fixed plate 7 through the connecting rod 14. A rotating structure is provided on the other side of the inner cavity of the fixed groove. The side of the cover body 4 away from the connecting rod 14 is connected to the fixed groove through the rotating structure.

[0025] The rotating structure of the present invention includes: a rotating rod 8 and a rotating roller 13 movably connected to the inner cavity of the fixed groove, the rotating rod 8 and the rotating roller 13 are connected through a synchronous belt 9, a moving block 12 is fixedly connected to one side of the synchronous belt 9, an electromagnet 10 is fixedly connected to the inner cavity of the fixed groove, a spring 11 is provided between the electromagnet 10 and the moving block 12, and the rotating rod 8 is fixedly connected to the cover body 4. The material of the moving block 12 is ferromagnetic, and the material of the moving block 12 can be metallic iron. When the electromagnet 10 is in the energized state, the electromagnet 10 and the moving block 12 are in a state of magnetic field attraction. Under the action of this suction force, the moving block 12 moves in the direction of the electromagnet 10, and the moving block 12 drives the synchronous belt 9 fixedly connected thereto to rotate, and the rotation of the synchronous belt 9 causes the rotating rod 8 to rotate. When the rotating rod 8 rotates, it drives the cover body 4 to rotate. At this time, the protective cover is in an open state, as shown in FIG. Figure 2As shown, when the electromagnet 10 is in the power-off state, the moving block 12 can be reset under the action of the rebound force of the spring 11. When the moving block 12 is reset, the moving block 12 drives the synchronous belt 9 to rotate in the reverse direction. The reverse rotation of the synchronous belt 9 causes the rotating rod 8 to rotate in the reverse direction, thereby allowing the protective cover to be in a closed state.

[0026] The shield 4 is L-shaped. When the protective shield is closed, the short sides of the shield 4 form a protective cover parallel to the fixed plate 7, while the long sides of the shield 4 form the side walls of the protective shield. The outer surface of the shield 4 is covered with a protective pad made of rubber. The provision of the protective pad improves the seal between adjacent shields 4 and protects the user from injury if the user accidentally touches the shield 4.

[0027] One end of the spring 11 is fixedly connected to the moving block 12, and the other end of the spring 11 is fixedly connected to the electromagnet 10. The outer surface of the moving block 12 is wrapped with a buffer pad, which can be made of rubber. By setting the buffer pad, the impact force of the moving block 12 when it moves can be reduced.

[0028] When the present application is in use, a button for controlling the opening and closing of the protective cover can be provided on the base 1. The electromagnet 10 model can be LS-P20 / 23S.

[0029] A distance sensor 5 and a camera 15 are fixedly connected to one side of the fixed plate 7 near the pickup head 3. The distance sensor 5 is an ultrasonic distance sensor, and its probe is parallel to the pickup head 3. When the microphone is in use, the camera 15 can be used to locate the user's mouth, and the distance sensor 5 can be used to detect the distance between the pickup head 3 and the user's mouth. A display 6 is fixed to the inside of the cover 4. When the protective cover is open, the display 6 can face the user, making it easy for the user to view the signal displayed on the display 6.

[0030] When the microphone is in use, the camera 15 and the distance sensor 5 upload the collected data to the controller in the microphone system. The controller causes the display 6 to display corresponding signals based on the collected data. The user can accurately judge the distance between the mouth and the pickup head 3 based on the display results, thereby facilitating the user to adjust the position of the pickup head 3 and ensuring the effectiveness of the microphone.

[0031] In some embodiments of the present application, the display 6 directly displays the distance value between the pickup head 3 and the user's mouth.

[0032] In some embodiments of the present application, the display 6 displays different colors according to the distance value between the pickup head 3 and the user's mouth. For example, if the distance value between the pickup head 3 and the user's mouth is too large, the display 6 displays red; if the distance value between the pickup head 3 and the user's mouth is moderate, the display 6 displays green; if the distance value between the pickup head 3 and the user's mouth is too small, the display 6 displays red. The user can directly judge the distance between his mouth and the pickup head 3 based on the color displayed on the display 6.

[0033] The electrical components involved in this application are all existing technologies. Those skilled in the art are familiar with their connection methods. Through these people, all the electrical components in this application are connected to their corresponding power supplies through wires, and according to actual conditions, appropriate controllers are selected to meet control requirements. The specific connections and control sequences are described below. The electrical connections between the electrical components are completed in a sequential working order. The detailed connection methods are well known in the art. The following mainly introduces the working principles and processes, and no further explanation of electrical control is given.

[0034] To sum up: when the microphone system is used, the user presses the button that controls the opening of the protective cover to energize the electromagnet 10. When the electromagnet 10 is energized, the electromagnet 10 and the adjacent moving block 12 are magnetically attracted to each other. Under the action of this suction force, the moving block 12 moves in the direction of the electromagnet 10. When the moving block 12 moves, it drives the synchronous belt 9 fixed to it to rotate, and the rotation of the synchronous belt 9 causes the rotating rod 8 to rotate. When the rotating rod 8 rotates, it drives the cover body 4 to rotate until the protective cover is in a fully open state, and the pickup head 3, ranging sensor 5, camera 15 and display 6 in the microphone system are all exposed.

[0035] When the protective cover is opened, the camera 15 locates the user's head, and the ranging sensor 5 measures the distance between the pickup head 3 and the user's head. The camera 15 and the ranging sensor 5 upload the collected data to the controller in the microphone system. The controller recognizes the user's mouth and displays the distance value between the user's mouth and the pickup head 3 on the display 6. The user can accurately adjust the distance between his or her mouth and the pickup head 3 according to the content displayed on the display 6 to ensure the use effect of the microphone system.

[0036] After the microphone system is used, the user presses the button that controls the closing of the protective cover. The electromagnet 10 is in a power-off state. Under the action of the rebound force of the spring 11, the moving block 12 is reset. When the moving block 12 is reset, it drives the synchronous belt 9 to rotate in the opposite direction. The reverse rotation of the synchronous belt 9 causes the cover body 4 to rotate in the opposite direction, thereby allowing the protective cover to be closed.
