[0026] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The present invention provides a conference microphone, comprising a base 100, a support rod 200, and a connecting column 300. The base 100 has a cavity for accommodating electronic components, and the base 100 is provided with a mounting hole 110 communicating with the cavity. The support rod 200 is used to mount a microphone body 400. The connecting column 300 is inserted into the mounting hole 110 to connect to the base 100. A mounting groove 310 is provided on the top of the connecting column 300. The support rod 200 is inserted into the mounting groove 310. The mounting groove 310 has a first limiting recess 311 along the circumference. The peripheral wall of the support rod 200 is provided with a first limiting boss 220. When the support rod 200 is inserted into the mounting groove 310, the first limiting boss 220 is snapped into the first limiting recess 311. The peripheral wall of the connecting column 300 is provided with a second limiting boss. The base 100 is provided with a second limiting recess 130. The second limiting recess 130 is arranged adjacent to the mounting hole 110. When the connecting column 300 is inserted into the mounting hole 110, the second limiting boss is snapped into the second limiting recess 130.

[0027] In a specific embodiment, the base 100 serves as the supporting foundation for the entire microphone. The base 100 has a cavity inside for accommodating electronic components such as audio amplifiers and signal processing circuits. The base 100 is provided with a mounting hole 110 connected to the cavity for receiving a connecting post 300 to achieve a secure connection with the support rod 200. The support rod 200 is used to mount the microphone body 400. Its length can be selected according to actual needs to provide sufficient support height and adjustment range. The peripheral wall of the support rod 200 is designed with a first limiting boss 220 for engaging with a first limiting recess 311 on the connecting post 300 to achieve circumferential fixation of the support rod 200. The connecting post 300 serves as a connector between the base 100 and the support rod 200 and is designed to be pluggable into the mounting hole 110 of the base 100. The top of the connecting post 300 is provided with a mounting slot 310 for receiving the support rod 200. The mounting slot 310 is circumferentially designed with a first retaining notch 311, which cooperates with the first retaining boss 220 on the support rod 200 to prevent the support rod 200 from rotating or falling horizontally. Furthermore, the connecting post 300 is also provided with a second retaining boss on its circumferential wall, which cooperates with the second retaining notch 130 on the base 100 to secure the connecting post 300 vertically. This dual retaining structure not only simplifies microphone installation and improves efficiency, but also ensures the microphone's stability and safety during use.

[0028] It should be noted that during installation, the connecting column 300 is first inserted into the mounting hole 110 of the base 100, so that the second limiting boss is snapped into the second limiting recess 130 to achieve preliminary fixation of the connecting column 300. Then, the support rod 200 is inserted into the mounting groove 310 of the connecting column 300, so that the first limiting boss 220 is snapped into the first limiting recess 311 to complete the installation of the support rod 200. By adjusting the height of the support rod 200, the position of the microphone body 400 can be easily adjusted to meet different meeting needs. The length and diameter of the support rod 200 can be selected according to actual needs to ensure sufficient support strength and adjustment range. The first limiting boss 220 is arranged on the peripheral wall of the support rod 200, and its shape and size match the first limiting recess 311 on the connecting column 300 to achieve circumferential fixation of the support rod 200. The top of the connecting post 300 has a mounting slot 310 for receiving the support rod 200. A first retaining notch 311 is circumferentially arranged around the mounting slot 310, which mates tightly with the first retaining boss 220 on the support rod 200. A second retaining boss, formed on the peripheral wall of the connecting post 300, mates with the second retaining notch 130 on the base 100, reinforcing the connecting post 300 and the base 100. This not only simplifies installation but also improves the overall stability of the microphone.

[0029] It is understood that the plug-in structure between the connecting column 300 and the base 100 and support rod 200 facilitates installation and removal of the microphone, improving installation efficiency. Furthermore, the dual-positioning structure, where the first position-limiting recess 311, the first position-limiting boss 220, the second position-limiting recess 130, and the second position-limiting boss cooperate in pairs, significantly improves the structural stability of the conference microphone, ensuring the safety and reliability of the microphone during use.

[0030] Reference Figure 3 The support rod 200 is provided with a positioning step 210 on its circumferential wall. When the connecting post 300 is fully inserted into the mounting groove 310 and contacts the bottom of the groove, the bottom wall of the positioning step 210 closely fits the top of the mounting groove 310, providing initial positioning and support. A first limiting boss 220 is located at the bottom of the positioning step 210. This ensures that when the support rod 200 is inserted into the mounting groove 310, the first limiting boss 220 can accurately engage the first limiting recess 311, thereby achieving stable circumferential fixation of the support rod 200.

[0031] Further, refer to Figure 1 and Figure 3 The support rod 200 and the connecting column 300 are respectively provided with a first thread 211 and a second thread 321. The first thread 211 is located at the top of the positioning step 210, while the second thread 321 is designed around the wall of the mounting groove 310 of the connecting column 300. By inserting the threaded sleeve 250 and rotating it, the threaded sleeve 250 forms a thread pair with the first thread 211 and the second thread 321, thereby firmly fixing the support rod 200 and the connecting column 300 together and enhancing the overall stability of the bracket.

[0032] Reference Figure 2 Furthermore, in some embodiments, the inner sidewall of the mounting slot 310 is provided with a retaining rib, while the peripheral wall of the support rod 200 is provided with a corresponding retaining groove 230. When the support rod 200 is inserted into the mounting slot 310, the retaining rib engages with the retaining groove 230, further limiting the axial movement of the support rod 200 and improving the stability of the bracket.

[0033] Optionally, refer to Figure 2 Two opposite first limiting recesses 311 are provided in the circumference of the mounting groove 310, and two first limiting bosses 220 are correspondingly provided on the support rod 200, which not only enhances the connection strength between the support rod 200 and the connecting column 300, but also enables the bracket to disperse stress more evenly when subjected to external force, thereby improving the durability of the overall structure.

[0034] Further, refer to Figure 1 and Figure 4The base 100 is provided with a positioning slot 120, and the peripheral wall of the connecting post 300 is designed with a limiting edge plate 320. When the connecting post 300 is inserted into the positioning slot 120, the limiting edge plate 320 will snap into the positioning slot 120, ensuring a secure connection between the connecting post 300 and the base 100. It also makes the installation of the connecting post 300 more convenient and improves installation efficiency.

[0035] It should be noted that the connecting post 300 is provided with a third thread 322 on the underside of the retaining side plate 320, and a corresponding installation space is reserved within the positioning slot 120 of the base 100. By inserting and rotating the retaining nut, the retaining nut and the third thread 322 form a thread pair, firmly fixing the connecting post 300 to the base 100 and enhancing the overall stability of the bracket.

[0036] It should be noted that, in some embodiments, the second limiting recess 130 is located in the positioning groove 120 and is connected to the mounting hole 110. This design not only simplifies the connection structure between the connecting column 300 and the base 100, but also makes it easier for the second limiting boss to snap into the second limiting recess 130, thereby improving the installation convenience and stability of the bracket and improving the compactness of the overall structure. In other embodiments, the second limiting recess 130 is completely independent from the mounting hole 110, and the position of the second limiting boss corresponds to the second limiting recess 130, which can also improve the stability of the connection between the connecting column 300 and the base 100, but will cause the volume of the connecting column 300 to increase. This is not the only limitation.

[0037] Reference Figure 2 and Figure 3 Specifically, the connecting post 300 is provided with an electrical contact protrusion 340, which electrically connects to the electronic components within the base 100. Meanwhile, the bottom of the support rod 200 is designed with an electrical connection slot 240, which contains electrical contacts. When the support rod 200 is inserted into the mounting slot 310, the electrical connection protrusion 340 inserts into the electrical connection slot 240 and makes close contact with the electrical contacts, thereby establishing an electrical connection between the electronic components and the microphone body 400.

[0038] Reference Figure 1 and Figure 4 It should be noted that the base 100 also integrates a panel assembly 140 and a switch button 150. These components are electrically connected to the electronic components within the base 100, allowing the user to conveniently control functions such as turning the microphone on and off and adjusting the volume through the panel assembly 140 and switch button 150. This not only improves the functionality of the stand, but also makes it more aesthetically pleasing and practical.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
