It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a microphone rod structure, including a microphone rod 1, a retaining spring 2, a limiting piece 3, and an earphone shell 4 with a first through hole 41;

[0033] The microphone rod 1 includes a microphone rod body 11 and a plug post 12 disposed on the microphone rod body 11. The plug post 12 has a side protrusion 121 on its side.

[0034] The retaining ring 2 is provided with a second through hole 21; the limiting piece 3 is provided with a third through hole 31, and the inner wall of the third through hole 31 is provided with a side limiting groove 32;

[0035] The end of the plug post 12 away from the microphone body 11 passes through the first through hole 41, the side protrusion 121 is interference-fitted into the second through hole, and the retaining spring 2 is fixedly sleeved on the plug post 12; the limiting piece 3 is sleeved on the plug post 12 through the third through hole 31, and the side protrusion 121 is inserted into the side limiting groove 32.

[0036] The side limiting groove 32 is equivalent to expanding the width of one side of the third through hole 31.

[0037] Specifically, such as Figure 4 As shown, firstly, the end of the plug 12 furthest from the microphone body 11 is passed through the first through hole 41. Then, the retaining spring 2 is sleeved on the plug 12. The retaining spring 2 is rotated so that the side protrusion 121 on the plug 12 is press-fitted with the second through hole 21 of the retaining spring 2, thereby fixing the retaining spring 2 on the plug 12. Afterwards, as... Figure 5 As shown, the limiting piece 3 is sleeved on the insertion post 12, and the side protrusion 121 is interference-fitted into the side limiting groove 32, thereby fixing the limiting piece 3 onto the insertion post 12. The retaining spring 2 and the limiting piece 3 limit the insertion post 12 within the first through hole 41. In this invention, the microphone rod structure has fewer components, lower manufacturing cost, and is easier to assemble.

[0038] In one embodiment, such as Figure 1 and Figure 2As shown, the microphone structure also includes a wear-resistant plate 5, which has a fourth through hole 51. The wear-resistant plate 5 is sleeved on the plug post 12 through the fourth through hole 51, and the opposite sides of the wear-resistant plate 5 abut against the earphone shell 4 and the retaining spring 2, respectively.

[0039] The wear-resistant plate 5 is placed between the retaining spring 2 and the earphone shell 4. During the rotation of the microphone rod 1, the retaining spring 2 does not directly contact the earphone shell 4. Because the wear-resistant plate 5 has wear-resistant properties, the service life of the microphone rod structure is extended.

[0040] In one embodiment, such as Figures 1 to 3 As shown, the side of the plug post 12 is also provided with a guide protrusion 122, and the inner wall of the second through hole 21 is provided with a first inner groove 22.

[0041] The guide protrusion 122 is inserted into the first inner groove 22, and the retaining spring 2 is movably sleeved on the insertion post 12.

[0042] The side protrusion 121 and the guide protrusion 122 are both located at the upper end of the side of the plug post 12; the first inner groove 22 is equivalent to having an enlarged hole on one side of the second through hole 21.

[0043] Specifically, such as Figure 3 As shown, during the process of the retaining spring 2 being sleeved on the insertion post 12, the first inner groove 22 moves along the guide protrusion 122. When the retaining spring 2 moves below the guide protrusion 122, at this time, the retaining spring 2 is movably sleeved on the insertion post 12; as Figure 4 As shown, the retaining ring 2 is rotated so that the side protrusion is inserted into the second through hole 21, thereby fixing the retaining ring 2 onto the insertion post 12.

[0044] In this embodiment, the design of the guide protrusion 122 and the first inner groove 22 ensures the smoothness of the snap ring 2 being fitted onto the plug post 12.

[0045] In one embodiment, such as Figure 1 and Figure 2 As shown, along the axial direction of the plug post 12, the width of the guide protrusion 122 is smaller than the width of the side protrusion 121;

[0046] The inner wall of the third through hole 31 is provided with a second inner groove 33, and the guide protrusion 122 is intermittently inserted into the second inner groove 33.

[0047] The second inner groove 33 is equivalent to having an enlarged hole on one side of the third through hole 31.

[0048] Specifically, when the retaining ring 2 and the limiting piece 3 are both fixedly sleeved on the insertion post 12, the lower end of the side protrusion 121 is interference-fitted into the second through hole 21, the upper end of the side protrusion 121 is inserted into the side limiting groove 32, and the guide protrusion 122 is inserted into the second inner groove 33, which further ensures the stability of the retaining ring 2 and the limiting piece 3 sleeved on the insertion post 12.

[0049] In one embodiment, such as Figure 6 and Figure 7 As shown, the earphone shell 4 is also provided with an annular protrusion 42, which surrounds the first through hole 41; the microphone body 11 is provided with an annular groove 111, which surrounds the plug post 12; the annular protrusion 42 is interference-fitted into the annular groove 111.

[0050] The first through hole 41 is a countersunk hole, and the annular protrusion 42 is disposed on the step of the countersunk hole.

[0051] In this embodiment, the annular protrusion 42 is interference-fitted into the interference groove, and the annular protrusion 42 is arranged around the first through hole 41, and the annular groove 111 is arranged around the insertion post 12. Thus, the annular protrusion 42 is equivalent to a sealing ring, ensuring the waterproof rating of the microphone rod structure.

[0052] In one embodiment, the inner wall of the annular groove 111 is a flexible sidewall, which is used to compress the annular protrusion 42.

[0053] The microphone body 11 is covered with a soft rubber sleeve, and the annular groove 111 is disposed on the soft rubber sleeve, so that the inner wall of the annular groove 111 is a flexible inner wall.

[0054] Specifically, when the annular protrusion 42 is inserted into the annular groove 111, the annular protrusion 42 will press against the inner wall of the annular groove 111, and the inner wall of the annular groove 111 will undergo elastic deformation, thereby ensuring the waterproof rating of the microphone structure and also achieving a damping feel when the microphone 1 rotates.

[0055] In one embodiment, such as Figure 6 As shown, the inner wall of the first through hole 41 is provided with circumferentially spaced inner protrusions 43, which are used to press the plug post 12.

[0056] The number of the inner protrusions 43 can be set according to actual needs. The inner protrusions 43 extend toward the center of the first through hole 41 and have a certain degree of elasticity.

[0057] Specifically, when the plug 12 is inserted into the first through hole 41, the plug 12 will press the inner protrusion 43, and the inner protrusion 43 will undergo elastic deformation and press the plug 12, thereby ensuring the stability of the plug 12 inserted into the first through hole 41.

[0058] In one embodiment, such as Figure 1 As shown, the microphone structure also includes a position switch 6 mounted on the earphone shell 4, and the limiting piece 3 is provided with a trigger protrusion 34; the trigger protrusion 34 is used to trigger the position switch 6.

[0059] The trigger protrusion 34 is disposed on the side of the limiting piece 3, and the position switch 6 includes, but is not limited to, a mute switch.

[0060] Specifically, rotating the microphone lever 1 will cause the limiting plate 3 to rotate. The triggering protrusion 34 of the limiting plate 3 can trigger the positioning switch 6. After the positioning switch 6 is triggered by the triggering protrusion 34, it will execute relevant commands such as mute.

[0061] Another embodiment of this utility model also provides an earphone, including the above-described microphone rod structure.

[0062] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
