[0004] The technical solution of the utility model is a sound amplification device for digital conferencing, comprising a base and a microphone. The microphone and the base are connected via a connecting tube, which comprises a telescopic tube and a rotating tube. One end of the telescopic tube is connected to the microphone, and the other end is connected to the rotating tube. The rotating tube is rotatably connected to the base, and the base is provided with a positioning groove that mates with the telescopic tube.

[0005] Furthermore, a universal tube is provided at one end of the microphone close to the telescopic tube, and two ends of the universal tube are respectively connected to the microphone and the telescopic tube.

[0006] Furthermore, a plurality of symmetrically distributed suction cups are provided on the bottom surface of the base, an end of the suction cup close to the base is provided with an external thread, and the base is provided with a threaded hole that matches the suction cup.

[0007] Furthermore, the positioning groove extends to the side of the base, and the side of the base is provided with a microphone groove matching the microphone, and the microphone groove is connected to the positioning groove.

[0020] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described clearly and completely below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0021] The specific implementation of the present invention will be described below with reference to the accompanying drawings:

[0022] like Figures 1 to 6 As shown, a sound amplification device for digital conferencing includes a base 1 and a microphone 21. The microphone 21 is connected to the base 1 via a connecting tube 2. The connecting tube 2 includes a telescopic tube 23 and a rotating tube 24. One end of the telescopic tube 23 is connected to the microphone 21, and the other end is connected to the rotating tube 24. The rotating tube 24 is rotatably connected to the base 1. The base 1 is provided with a positioning groove 15 that cooperates with the telescopic tube 23. The telescopic tube 23 adjusts the height of the microphone 21, making it easier to store the microphone 21. The rotating tube 24 drives the telescopic tube 23 and the microphone 21 to rotate relative to the base 1, embedding the telescopic tube 23 in the positioning groove 15, further reducing the space occupied by the microphone 21 and the connecting tube 2, improving the integration of the device, and reducing the possibility of damage to the microphone 21 due to bumps during transportation of the device as a whole.

[0023] A universal tube 22 is provided at one end of the microphone 21 close to the telescopic tube 23, and the two ends of the universal tube 22 are respectively connected to the microphone 21 and the telescopic tube 23. The characteristics of the universal tube 22 make it easy to adjust the direction of the microphone 21. One end of the rotating tube 24 is connected to the telescopic tube 23, and the other end extends into the interior of the base 1. The base 1 is provided with a guide tube 16 that cooperates with the rotating tube 24. When the rotating tube 24 rotates around the guide tube 16, it drives the microphone 21 and the telescopic tube 23 to rotate together. A spring 241 is provided on the outer periphery of the guide tube 16, one end of the spring 241 contacts the end of the rotating tube 24, and the other end contacts the inner wall of the base 1. A paddle 231 is provided on the side of the rotating tube 24 away from the base 1. By applying external force to the paddle 231, the connecting tube 2 as a whole moves along the axial direction of the guide tube 16. When the telescopic tube 23 leaves the positioning slot 15, the connecting tube 2 can rotate around the guide tube 16. When the telescopic tube 23 is above the positioning slot 15, the elastic force of the spring 241 automatically inserts the telescopic tube 23 into the positioning slot 15. After the telescopic tube 23 is inserted into the positioning slot 15, the connecting tube 2 as a whole cannot rotate freely.

[0024] The positioning slot 15 extends to the side of the base 1. The side of the base 1 is provided with a microphone slot 152 that mates with the microphone 21. The microphone slot 152 is connected to the positioning slot 15. By bending the universal tube 22, the microphone 21 is inserted into the microphone slot 152 and stored. A flip cover 151 is provided on the microphone slot 152, which can conform to the shape of the microphone 21. One side of the flip cover 151 is hinged to the base 1, and the other side is fixedly connected to the base 1 via a buckle 153. The freely openable flip cover 151 facilitates the fixation of the microphone 21 and provides protection for the microphone 21, preventing dust and impurities from falling into the microphone 21 or external impact after storage.

[0025] The bottom surface of the base 1 is provided with a plurality of symmetrically distributed suction cups 14. When the base 1 is placed on a table, the suction cups 14 are used to improve the stability of the base 1. The suction cup 14 is provided with an external thread at one end close to the base 1, and the base 1 is provided with a threaded hole that matches the suction cup 14. The suction cup 14 is a vulnerable part, and the detachable suction cup 14 is easy to replace. A speaker 11 and a button 13 are provided on the base 1. The speaker 11 can amplify and broadcast the received sound signal, making it convenient for the user to receive external audio information and control the sound amplification equipment through the button 13. A plurality of indicator lights 12 are provided on the base 1, and the working status of the sound amplification equipment can be judged by the indicator lights 12.

[0026] The working principle of the specific embodiment of the utility model is as follows: When the sound amplification device is in normal use, the telescopic tube 23 is embedded in the positioning groove 15, so that the connecting tube 2 remains in a stable state. When the microphone 21 needs to be stored, the telescopic tube 23 is shortened to lower the height of the microphone 21. The paddle 231 is pulled to move the connecting tube 2 out of the positioning groove 15 along the axis of the guide tube 16. The connecting tube 2 is then rotated around the guide tube 16. The paddle 231 is released. Under the action of the spring 241, the telescopic tube 23 is re-embedded in the positioning groove 15. The universal tube 22 is bent to allow the microphone 21 to be embedded in the microphone groove 152. The flip cover 151 is then closed to secure and protect the microphone 21.
