A snap groove 211 is disposed on the inner wall surface of the upright pole 2 corresponding to the plug connector. Thus, when assembling the base 1 and the upright pole 2, one end of the upright pole 2 is simply inserted into the plug connector 11, and the snap portion 111 and the snap groove 211 cooperate to securely connect the upright pole 2 and the base 1. This makes the operation simple, and the assembly between the upright pole 2 and the base 1 is convenient and quick.

[0030] Specifically, the snap portion 111 is provided on the side of the plug connector 11, and the snap groove 211 is provided on the inner wall surface of the vertical pole 2. Furthermore, the desktop microphone also includes a fixing member 4, which passes through the base 1 from the inside and is connected to the vertical pole 2. The provision of the fixing member 4 can further enhance the connection stability between the base 1 and the vertical pole 2, making the desktop microphone more stable during use, preventing the vertical pole 2 from accidentally detaching from the base 1, and enhancing the reliability of the desktop microphone. Specifically, the fixing member 4 is a screw, and a threaded hole is provided at the end of the vertical pole 2 that is inserted into the plug connector 11, and the screw is screwed into the threaded hole of the vertical pole 2.

[0031] On the top surface of the base 1, the connector 11 is provided with an abutment ridge 113 around its perimeter, against which the end of the upright 2 abuts. This abutment of the upright 2 end against the abutment ridge 113 limits the insertion of the upright 2 into the connector 11, allowing the latch 111 to precisely engage with the latch groove 211. Furthermore, after the upright 2 is assembled, the abutment ridge 113 supports the upright 2, ensuring that the latch 111 remains firmly engaged in the latch groove 211.

[0032] Furthermore, a first through hole 113a is formed on the abutting ridge 113, and the fixing member 4 passes through the first through hole 113a and is connected to the upright pole 2. The first through hole 113a facilitates the fixing member 4 to pass through the abutting ridge 113 and be connected to the upright pole 2.

[0033] A snap portion 111 is provided on one side and the opposite side of the plug connector 11, and a snap groove 211 is provided on the inner wall surface of the vertical pole 2 corresponding to the snap portion 111.

Even if one snap portion 111 is damaged, the other snap portion 111 can maintain the connection between the vertical pole 2 and the base 1, thereby improving the reliability of the desktop microphone. Correspondingly, two fixing members 4 are also provided, and the two fixing members 4 pass through the other two sides of the plug connector 11 and are connected to the vertical pole 2.

[0034] Further integration Figure 4 As shown, the microphone boom 3 is provided with a mounting cavity 323 that opens toward the base 1. The vertical pole 2 is rotatably mounted in the mounting cavity 323, and the rotational connection position of the vertical pole 2 is located on a side away from the opening of the mounting cavity 323, so that the microphone boom 3 can be rotated to any angle without the rotational connection position of the vertical pole 2 being exposed outside the mounting cavity 323. The rotational connection between the vertical pole 2 and the microphone boom 3 facilitates the user to adjust the angle of use. The rotational connection position of the vertical pole 2 is located on a side away from the opening of the mounting cavity 323, so that the rotational connection position of the vertical pole 2 is always hidden in the mounting cavity 323. No matter how the user rotates the microphone boom 3, the rotational connection position of the vertical pole 2 will not be exposed from the mounting cavity 323.

[0035] Further integration Figure 4 As shown, the plug connector 11 is axially extended with a first wiring channel 112 that connects to the interior of the base 1. The upright pole 2 is axially extended with a second wiring channel 21 that connects to the first wiring channel 112. The microphone boom 3 is provided with a third wiring channel 321 that connects to the second wiring channel 21. The base 1 is provided with a main control circuit board 12, and the microphone boom 3 is provided with a microphone unit 33.

The inner pole frame 32 can provide additional support, making the microphone pole 3 more stable, and improving the structural strength and durability of the microphone pole 3. The third wiring channel 321 opened on the inner pole frame 32 can provide strong protection for the wire 5. Specifically, the installation cavity 323 is provided on the inner pole frame 32, and the microphone unit 33 is installed on the end of the outer shell 31 away from the vertical pole 2. The microphone unit 33 can be a microphone capacitor.

[0038] like Figure 5 and Figure 6As shown, the third wiring channel 321 is provided with an opening on the side of the inner rod frame 32 away from the base 1, and the two inner side walls of the third wiring channel 321 are provided with narrowing ribs 322. The narrowing ribs 322 not only improve the structural strength of the inner rod frame 32, but also reduce the weight of the inner rod frame 32. They can also further narrow the third wiring channel 321 and improve the position limiting of the wire 5. The opening side of the third wiring channel 321 on the side of the inner rod frame 32 away from the base 1 facilitates the installation of the wire 5 led out of the second wiring channel 21 into the third wiring channel 321. The narrowing ribs 322 are provided with multiple limiting ribs 322a staggered in the extension direction of the third wiring channel 321. The wire 5 is located below the limiting ribs 322a; the limiting ribs 322a can further limit the different positions of the wire 5, making the wire 5 more orderly and more stable in the third wiring channel 321. On either side of the plurality of limiting ribs 322a, the narrowing ribs 322 are provided with a first narrowing opening 322b and a second narrowing opening 322c. The first narrowing opening 322b and the second narrowing opening 322c are staggered in the axial projection direction of the inner rod frame 32. The staggered first narrowing opening 322b and the second narrowing opening 322c can limit the position of the wire 5 passing through them.
