[0002] Microphones, also known as microphones, are energy conversion devices that convert sound signals into electrical signals. In recent years, with the continuous development of microphone technology, microphones have been widely used in business meetings, online live broadcasts, home KTVs, etc., especially business meetings. Since microphones used for business meetings are small in size and easy to use, they can be used in various office occasions.

[0003] A Chinese patent with publication number CN212588515U was searched and disclosed a microphone housing, a packaging structure for a microphone and a microphone, which includes a housing body for forming a sound cavity and a connecting part connected to the housing body for connecting the microphone housing.

[0004] Based on the above search and combined with the prior art, we found that:

[0006] In order to solve the above technical problems, the utility model proposes a shell connection structure of a microphone, in which the upper shell moves downward, driving the limit block on the U-shaped block to move downward, thereby squeezing the card block. By setting the torsion spring, the limit block can be located below the card block, and the upper shell and the lower shell are clamped and fixed. When releasing the fixation, the moving block can be pressed at the same time to drive the protrusion on the sliding column to move, thereby squeezing the limit block and releasing the restriction on the card block.

[0009] The connecting mechanism includes protrusions fixedly connected to one end of the two sliding columns, the other ends of the two sliding columns are fixedly connected to moving blocks, the bottom of the upper shell is fixedly connected to two U-shaped blocks, the two U-shaped blocks are fixedly connected to connecting columns, the circumferential outer walls of the two connecting columns are rotatably sleeved with limiting blocks, the inner wall of the lower shell is fixedly connected to two clamping blocks, the clamping blocks are adapted to the limiting blocks, and the ends of the two protrusions close to each other are both in contact with the limiting blocks.

[0010] In some embodiments, a return spring is sleeved on each of the two sliding columns, and two ends of the return spring are fixedly connected to the fixed block and the protrusion respectively.

[0011] In some embodiments, a torsion spring is sleeved on each of the two connecting columns, and two ends of the torsion spring are respectively fixedly connected to the U-shaped block and the limiting block.

[0012] In some embodiments, the inner wall of the lower shell is fixedly connected to two sliding grooves, and the two sliding grooves are slidably connected to long blocks, and the tops of the two long blocks are commonly fixedly connected to the upper shell.

[0013] In some embodiments, two limiting tubes are fixedly connected to the bottom inner wall of the lower shell, limiting columns are slidably sleeved in the two limiting tubes, and the top ends of the two limiting columns are fixedly connected to the upper shell.

[0014] In some embodiments, a microphone assembly is installed on the bottom inner wall of the lower housing.

[0015] Compared with the prior art, the present invention has the following significant advantages:

[0016] The utility model limits and fixes the upper shell and the lower shell by means of the sliding groove and the elongated block. The upper shell moves downward to drive the limit block on the U-shaped block to move downward to squeeze the clamping block. By setting the torsion spring, the limit block can be located below the clamping block to clamp and fix the upper shell and the lower shell. When releasing the fixation, the moving block can be pressed at the same time to drive the convex block on the sliding column to move to squeeze the limit block to release the restriction on the clamping block. Then, the upper shell can be lifted upward at the same time to release the clamping fixation of the lower shell, thereby facilitating the connection of the shell of the microphone, facilitating the clamping and disassembly, and being simple to operate.

[0017] The invention solves the problem that most existing devices use too many screws for fixing, which makes the disassembly and assembly process of the shell too complicated, easily damages the shell, has certain limitations, and reduces the reuse rate of the shell.
