Abstract

The present application provides a rotating mechanism and headphones. The rotating mechanism includes a mounting frame, a first connecting member, a rotating assembly, and a second connecting member. The first connecting member is connected to the mounting frame, and the first connecting member is also used to connect to the ear shell, so that the mounting frame is fixedly connected to the ear shell. The rotating assembly is passed through the mounting frame and is rotatably connected to the mounting frame. The rotating assembly is fixedly connected to the microphone rod. The second connecting member is connected to the rotating assembly, and the second connecting member is also used to connect to the microphone rod, so that the rotating assembly is fixedly connected to the microphone rod. Because the contact between the rotating assembly and the mounting frame is metal-to-plastic contact, the wear of the rotating assembly and the mounting frame is suppressed, thereby suppressing the problem of the microphone rod jamming and friction noise during rotation, and at the same time suppressing the problem of powder shedding on the mounting frame, thereby suppressing the problem of powder shedding on the headphones.

Description

Technical Field

[0001] The present invention relates to the technical field of headphones, and in particular to a rotating mechanism and a headphone. Background Art

[0002] In existing headphones, the microphone stem is rotatably connected to the ear shell. However, since the microphone stem directly contacts the ear shell during rotation, friction occurs between the microphone stem and the ear shell. Furthermore, since the wear resistance of the microphone stem and the ear shell is relatively poor, the microphone stem and the ear shell wear quickly, and the friction surface wears quickly, which in turn makes the microphone stem and the ear shell more susceptible to powder shedding. In addition, the friction surface is more susceptible to powder shedding, which in turn makes the rotation stability and smoothness of the microphone stem poor. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a rotation mechanism and a headphone with high rotation stability and smoothness.

[0009] The second connecting member is connected to the rotating assembly, and the second connecting member is also used to connect to the microphone rod, so that the rotating assembly is used to be fixedly connected to the microphone rod.

[0012] The fixing member is provided with a sleeve hole, and a portion of the rotating shaft is located in the sleeve hole and fixedly sleeved with the fixing member.

[0013] In one embodiment, a portion of the rotating assembly adjacent to the microphone rod protrudes from the mounting bracket.

[0014] A headphone comprises an ear shell, a microphone rod, and the rotating mechanism described in any of the above embodiments, wherein the first connecting member is respectively connected to the ear shell and the mounting frame to fix the mounting frame to the ear shell, and the second connecting member is respectively connected to the microphone rod and the rotating assembly to fix the rotating assembly to the microphone rod.

[0015] In one embodiment, the microphone rod is provided with a limiting groove, the rotating assembly is provided with a first limiting portion, and the first limiting portion is located in the limiting groove and connected to the microphone rod.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. When the microphone rod rotates, the rotating assembly contacts the mounting frame and rotates relative to it, avoiding direct contact between the microphone rod and the ear shell, thereby reducing the wear of the microphone rod and the ear shell, and avoiding the problem of powder falling off the microphone rod and the ear shell.

[0022] 2.

[0034] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] The present application provides a rotation mechanism, including a mounting frame, a first connecting member, a rotation assembly, and a second connecting member. The first connecting member is connected to the mounting frame and is also used to connect to the ear shell, so that the mounting frame is fixedly connected to the ear shell. The rotation assembly is inserted into the mounting frame and is rotationally connected to the mounting frame. The second connecting member is connected to the rotation assembly and is also used to connect to the microphone rod, so that the rotation assembly is fixedly connected to the microphone rod. The present application also provides a headphone, including the ear shell, the microphone rod, and the above-mentioned rotation mechanism. The first connecting member is respectively connected to the ear shell and the mounting frame, so that the mounting frame is fixedly connected to the ear shell. The second connecting member is respectively connected to the microphone rod and the rotation assembly, so that the rotation assembly is fixedly connected to the microphone rod.

[0038] In the aforementioned rotating mechanism and headphones, when the microphone rod rotates, the rotating assembly and mounting frame contact and rotate relative to each other, preventing direct contact between the microphone rod and the ear shell, thereby reducing wear on the microphone rod and ear shell, and preventing the problem of powder shedding from the microphone rod and ear shell. Furthermore, when the microphone rod rotates, the rotating assembly and mounting frame contact and rotate relative to each other, creating friction surfaces between the rotating assembly and mounting frame. Since both the rotating assembly and mounting frame are wear-resistant structures, wear on the friction surfaces is reduced, improving the smoothness and stability of the microphone rod's rotation. Furthermore, since the ear shell and microphone rod are relatively large, their manufacturing costs significantly impact the overall manufacturing cost of the headphones. However, since the ear shell and microphone rod do not need to be in direct contact, the wear resistance of the ear shell and microphone rod can be reduced, reducing the manufacturing costs of the ear shell and microphone rod, and thus, the manufacturing cost of the headphones.

[0039] To better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below with reference to specific embodiments:

[0040] Please refer to Figures 1 to 4 A headset 10 according to one embodiment includes an earpiece 100, a microphone rod 200, and a rotating mechanism 300. The rotating mechanism 300 is connected to the earpiece 100, and the microphone rod 200 is connected to the rotating mechanism 300, so that the microphone rod 200 is rotatably connected to the earpiece 100 via the rotating mechanism 300. Furthermore, the rotating mechanism 300 includes a mounting frame 310, a first connecting member 320, a rotating assembly 330, and a second connecting member 340. The first connecting member 320 is connected to the mounting frame 310 and is also connected to the earpiece 100, so that the mounting frame 310 and the earpiece 100 are fixedly connected. The rotating assembly 330 is disposed through the mounting frame 310 and is rotatably connected to the mounting frame 310. The second connecting member 340 is connected to the rotating assembly 330 and is also connected to the microphone rod 200, so that the rotating assembly 330 and the microphone rod 200 are fixedly connected.

[0041] In this embodiment, both the rotating assembly 330 and the mounting frame 310 are wear-resistant structures. The first connecting member 320 is connected to the mounting frame 310 and the rotating assembly 330, respectively, so that the mounting frame 310 is fixedly mounted on the concha 100. The second connecting member 340 is connected to the microphone rod 200 and the rotating assembly 330, respectively, so that the microphone rod 200 is fixedly mounted on the rotating assembly 330. Since the rotating assembly 330 passes through the mounting frame 310 and is rotationally connected to the mounting frame 310, the microphone rod 200 is rotationally connected to the mounting frame 310 through the rotating assembly 330. Since the mounting frame 310 is fixedly mounted on the concha 100, the microphone rod 200 is rotationally connected to the concha 100 through the rotating assembly 330 and the mounting frame 310.

[0042] In the aforementioned headphone 10 and rotating mechanism 300, when the microphone lever 200 rotates, the rotating assembly 330 and the mounting frame 310 come into contact and rotate relative to each other, thereby preventing direct contact between the microphone lever 200 and the concha 100. This reduces wear on the microphone lever 200 and the concha 100, and prevents the problem of powder shedding from the microphone lever 200 and the concha 100. Furthermore, when the microphone lever 200 rotates, the rotating assembly 330 and the mounting frame 310 come into contact and rotate relative to each other, creating friction surfaces between the rotating assembly 330 and the mounting frame 310. Since both the rotating assembly 330 and the mounting frame 310 are wear-resistant structures, wear on the friction surfaces is reduced, thereby improving the smoothness and stability of the rotation of the microphone lever 200. In addition, due to the large volume of the ear shell 100 and the microphone stem 200, the manufacturing cost of the ear shell 100 and the microphone stem 200 has a greater impact on the manufacturing cost of the headphone 10. Since the ear shell 100 and the microphone stem 200 do not need to be in direct contact, the wear resistance of the ear shell 100 and the microphone stem 200 can be lower, thereby reducing the manufacturing cost of the ear shell 100 and the microphone stem 200, and further reducing the manufacturing cost of the headphone 10.

[0043] In one embodiment, the rotating assembly 330 is a stainless steel structure, that is, the rotating assembly 330 is made of stainless steel to provide good wear resistance. Of course, in other embodiments, the rotating assembly 330 can also be a polyoxymethylene resin structure, copper, ceramic, hard plastic, or other existing wear-resistant structures.

[0044] In one embodiment, the mounting frame 310 is a polyoxymethylene resin structure, that is, the mounting frame 310 is made of polyoxymethylene resin, so that the mounting frame 310 has good wear resistance. Of course, in other embodiments, the rotating assembly 330 can also be made of stainless steel, copper, ceramic, hard plastic, or other existing wear-resistant structures.

[0045] like Figure 2 As shown, the first connecting member 320 is a fastener. The first connecting member 320 is disposed through the mounting frame 310, with the first end of the first connecting member 320 abutting the mounting frame 310 and the second end of the first connecting member 320 connected to the concha 100, thereby securing the mounting frame 310 to the concha 100. It is understood that the first connecting member 320 may be a screw, bolt, or other existing fastener. Of course, in other embodiments, the first connecting member 320 may also be an adhesive structure, with the mounting frame 310 being secured to the concha 100 via the first connecting member 320.

[0046] like Figure 4As shown, in one embodiment, the mounting frame 310 is provided with a rotating hole 311, and the rotating assembly 330 includes a rotating shaft 331 and a fixing member 332. The rotating shaft 331 is passed through the rotating hole 311 and is rotatably connected to the mounting frame 310. The fixing member 332 is connected to the rotating shaft 331. Parts of the rotating shaft 331 and the fixing member 332 are respectively abutted against opposite sides of the mounting frame 310. The second connecting member 340 is passed through the fixing member 332 and is connected to the rotating shaft 331. In this embodiment, the second connecting member 340 is also used to pass through the microphone rod 200, and the first end of the second connecting member 340 is also used to abut against the microphone rod 200. The second connecting member 340 is passed through the fixing member 332, and the second end of the second connecting member 340 is connected to the rotating shaft 331. The second end of the second connecting member 340 and the fixing member 332 are used to clamp the microphone rod 200 so that the microphone rod 200 is fixedly connected to the rotating assembly 330 through the second connecting member 340, so as to realize the synchronous rotation of the microphone rod 200 and the rotating assembly 330.

[0047] In one embodiment, the rotating shaft 331 is a stainless steel structure, that is, the rotating shaft 331 is made of stainless steel to provide good wear resistance. Of course, in other embodiments, the rotating shaft 331 can also be a polyoxymethylene resin structure, copper, ceramic, hard plastic, or other existing wear-resistant structures.

[0048] In one embodiment, the fixing member 332 is a stainless steel structure, that is, the fixing member 332 is made of stainless steel to provide good wear resistance. Of course, in other embodiments, the fixing member 332 can also be a polyoxymethylene resin structure, copper, ceramic, hard plastic, or other existing wear-resistant structures.

[0049] like Figure 4 As shown, in one embodiment, the rotating assembly 330 further includes a damping member 333. The damping member 333 elastically abuts the rotating shaft 331 and the mounting bracket 310, respectively, so that the rotating shaft 331 elastically abuts the mounting bracket 310 via the damping member 333. In this embodiment, the damping member 333 is an elastic structure, with opposite sides of the damping member 333 elastically abutting the rotating shaft 331 and the mounting bracket 310, respectively. This provides a damping effect during the rotation of the microphone 200, thereby improving the rotation effect of the microphone 200. In one embodiment, the damping member 333 is a silicone structure. Of course, in another embodiment, the damping member 333 can also be a rubber member or other existing elastic structure.

[0050] like Figure 4 and Figure 5As shown, in one embodiment, the fixing member 332 defines a sleeve hole 3321, and a portion of the rotating shaft 331 is located within the sleeve hole 3321 and is fixedly sleeved with the fixing member 332. In this embodiment, the fixing member 332 is sleeved on the rotating shaft 331, and the second connecting member 340 is passed through the fixing member 332 and connected to the rotating shaft 331. The first end of the second connecting member 340 abuts against the fixing member 332 through the microphone rod 200, so that the fixing member 332 is clamped between the microphone rod 200 and the mounting bracket 310, thereby securing the fixing member 332 to the rotating shaft 331.

[0051] like Figure 5 As shown, the rotating shaft 331 further includes a shaft body 3311 and a second limiting portion 3312 connected to each other. The shaft body 3311 is inserted into the rotating hole 311, and the fixing member 332 is connected to the shaft body 3311. The fixing member 332 and the second limiting portion 3312 respectively abut against opposite sides of the mounting bracket 310. The second connecting member 340 is inserted into the fixing member 332 and is threadedly connected to the shaft body 3311. In this embodiment, a portion of the shaft body 3311 is located in the sleeve hole 3321 and is fixedly sleeved with the fixing member 332.

[0052] like Figure 4 As shown, in one embodiment, the portion of the rotating assembly 330 adjacent to the microphone rod 200 protrudes from the mounting bracket 310. In this embodiment, the portion of the rotating assembly 330 adjacent to the microphone rod 200 abuts against the microphone rod 200. Since the portion of the rotating assembly 330 adjacent to the microphone rod 200 protrudes from the mounting bracket 310, a gap exists between the microphone rod 200 and the mounting bracket 310, thereby preventing contact between the microphone rod 200 and the mounting bracket 310. This prevents friction between the microphone rod 200 and the mounting bracket 310 during rotation, reduces wear on the microphone rod 200 and the ear shell 100, and suppresses jamming and friction noise of the microphone rod 200 during rotation, while also preventing powder loss from the microphone rod 200 and the ear shell 100.

[0053] like Figure 5 As shown, further, the second connecting member 340 is a fastener, the microphone rod 200 is provided with a first avoidance hole 201, the fixing member 332 is provided with a second avoidance hole 3322, and the rotating shaft 331 is provided with a threaded hole 3310a. The second connecting member 340 is sequentially inserted into the first avoidance hole 201 and the second avoidance hole 3322, and the first end of the second connecting member 340 abuts against the microphone rod 200, and the second end of the second connecting member 340 is located in the threaded hole 3310a and is threadedly connected to the rotating shaft 331, so that the microphone rod 200 is fixedly connected to the rotating assembly 330, thereby enabling the microphone rod 200 to be rotatably connected to the mounting bracket 310 through the rotating assembly 330. Of course, in other embodiments, the second connecting member 340 can also be a bonding structure, and the microphone rod 200 is fixedly bonded to the rotating assembly 330 through the second connecting member 340.

[0054] like Figure 4 As shown, in one embodiment, the microphone rod 200 is provided with a limiting slot 202, and the rotating assembly 330 is provided with a first limiting portion 334. The first limiting portion 334 is located in the limiting slot 202 and connected to the microphone rod 200 to prevent the rotating assembly 330 and the microphone rod 200 from rotating relative to each other, thereby ensuring that the rotating assembly 330 and the microphone rod 200 rotate synchronously, thereby avoiding rotational instability of the microphone rod 200.

[0055] like Figure 2 and Figure 6 As shown, in one embodiment, the headset 10 further includes an elastic abutment 400, which is fixedly connected to the microphone rod 200. The elastic abutment 400 also slides against the mounting bracket 310. The mounting bracket 310 has a prompt protrusion 310a protruding along the sliding path of the elastic abutment 400. The prompt protrusion 310a abuts against the elastic abutment 400 when aligned with the elastic abutment 400. In this embodiment, when the microphone rod 200 rotates, the elastic abutment 400 slides against the mounting bracket 310. When the microphone rod 200 rotates to a predetermined position, the prompt protrusion 310a aligns with and abuts the elastic abutment 400, causing the rotational resistance of the microphone rod 200 to change, thereby prompting the user that the microphone rod 200 has rotated to the predetermined position.

[0056] like Figure 6 As shown, further, the elastic abutment member 400 is a spring structure, so that the elastic abutment member 400 can elastically abut against the mounting bracket 310, while improving the installation convenience of the elastic abutment member 400. It is understood that the elastic abutment member 400 can also be a silicone structure, a spring structure or other existing elastic structures.

[0057] like Figure 2 As shown, the headset 10 further includes a start switch 500. The trigger end of the start switch 500 is located in the sliding path of the microphone rod 200. The microphone rod 200 contacts the trigger end when the prompt protrusion 310a abuts the elastic abutment 400. In this embodiment, the start switch 500 is used to activate the call function of the microphone. The headset 10 also includes a circuit board 600, which is mounted on the ear shell 100. The start switch 500 is mounted on the circuit board 600. The trigger end of the start switch 500 is located in the sliding path of the microphone rod 200. When the prompt protrusion 310a abuts the elastic abutment 400, the resistance to the rotation of the microphone rod 200 changes, prompting the user that the microphone rod 200 has rotated to the correct position. Simultaneously, the microphone rod 200 triggers the trigger end of the start switch 500, activating the call function of the microphone. In this way, when the resistance of the microphone rod 200 changes, the call function of the microphone is turned on, so that the user can know whether the call function of the microphone is turned on when rotating the microphone rod 200, which improves the convenience of turning on the call function of the microphone.

[0058] In one embodiment, the elastic abutment member 400 is provided with an abutment protrusion, which slides and abuts against the mounting frame 310, thereby reducing the abutment area between the elastic abutment member 400 and the mounting frame 310 and reducing the sliding resistance of the elastic abutment member 400. Since the elastic abutment member 400 is connected to the microphone rod 200, the rotation resistance of the microphone rod 200 is reduced, thereby improving the smoothness of the rotation of the microphone rod 200.

[0059] like Figure 6 As shown, in one embodiment, the mounting frame 310 is formed with a rotation groove 312, and a portion of the elastic abutment 400 is located in the rotation groove 312 and slides against the groove wall of the rotation groove 312, thereby preventing other parts from hindering the sliding of the elastic abutment 400, improving the smoothness of the sliding of the elastic abutment 400, and thereby improving the comfortable rotation of the microphone rod 200.

[0060] like Figure 2 As shown, in one embodiment, the ear shell 100 is formed with a mounting groove 101. The mounting bracket 310 is located in the mounting groove 101 and fixedly connected to the mounting bracket 310, so that the mounting bracket 310 overlaps with the ear shell 100, thereby improving the structural compactness of the headphone 10. The ear shell 100 also has a protrusion avoidance hole formed on the side. The microphone rod 200 is inserted through the protrusion avoidance hole and protrudes from the ear shell 100, so that the microphone rod 200 extends from the side of the ear shell 100. This prevents the microphone rod 200 from colliding with the ground first after the headphone 10 is dropped, reduces the impact force of the microphone rod 200 on the ground after the headphone 10 is dropped, and improves the service life of the microphone rod 200.

[0061] like Figure 4 As shown, in one embodiment, the microphone rod 200 includes a rigid body 210 and a soft covering body 220. The soft covering body 220 has a lower hardness than the rigid body 210. A second connector 340 is connected to the rigid body 210 and the mounting bracket 310, respectively, to securely connect the rigid body 210 to the microphone rod 200. The soft covering body 220 covers the portion connected to the rigid body 210 and is disposed through the side of the earpiece 100 that extends through the relief hole. In this embodiment, because the soft covering body 220 covers the rigid body 210 and protrudes from the side of the earpiece 100, the portion of the microphone rod 200 that protrudes from the earpiece 100 is softer, improving user comfort when rotating the microphone rod 200 while reducing the chance of the microphone rod 200 injuring the user.

[0062] like Figure 4As shown, the mounting bracket 310 further includes a stabilizing protrusion 310b protruding from the mounting bracket 310. The stabilizing protrusion 310b contacts the rigid body 210 and is arranged along the rotation path of the rigid body 210. The stabilizing protrusion 310b is spaced apart from the rotating assembly 330. In this embodiment, when the microphone lever 200 rotates, the rigid body 210 is not only connected to the rotating assembly 330 but also contacts the stabilizing protrusion 310b. The rotating assembly 330 is spaced apart from the stabilizing protrusion 310b. This ensures greater rotational stability and smoother rotation of the microphone lever 200.

[0063] like Figure 4 As shown, further, a gap exists between the soft covering body 220 and the mounting frame 310 to prevent contact between the soft covering body 220 and the mounting frame 310, thereby avoiding the problem of indentation on the soft covering body 220. At the same time, the force-bearing area of ​​the soft covering body 220 is reduced, reducing the resistance encountered by the soft covering body 220 during rotation, thereby improving the smooth rotation of the microphone rod 200. Furthermore, the soft covering body 220 and the extended avoidance hole are clearance-fitted to prevent contact between the soft covering body 220 and the ear shell 100, thereby avoiding the problem of indentation on the soft covering body 220. At the same time, the force-bearing area of ​​the soft covering body 220 is reduced, reducing the resistance encountered by the soft covering body 220 during rotation, thereby improving the smooth rotation of the microphone rod 200.

[0064] In one embodiment, the rotating mechanism 300 further includes a Teflon layer that covers the rotating assembly 330 and contacts the mounting frame 310, such that the rotating assembly 330 is rotatably connected to the mounting frame 310 via the Teflon layer. In this embodiment, the high wear resistance of the Teflon layer enhances the smoothness and stability of the rotation of the rotating assembly 330, thereby enhancing the smoothness and stability of the rotation of the microphone rod 200.

[0065] like Figure 4 and Figure 5As shown in one embodiment, when installing the microphone rod 200, first, the rotating shaft 331 is passed through the rotating hole 311 of the mounting frame 310, so that the second limiting portion 3312 of the rotating shaft 331 abuts against the mounting frame 310, and then the fixing member 332 is connected to the end of the rotating shaft 331 away from the second limiting portion 3312, so that the fixing member 332 and the second limiting portion 3312 respectively abut against the opposite sides of the mounting frame 310, and then the first avoiding hole 201 of the microphone rod 200 is connected to the fixing member 332. The second avoiding hole 3322 of the first avoiding hole 201 and the second avoiding hole 3322 are aligned, and then the second connecting member 340 is sequentially inserted into the first avoiding hole 201 and the second avoiding hole 3322, and then the second connecting member 340 is screwed so that the first end of the second connecting member 340 abuts against the microphone rod 200, and the second end of the second connecting member 340 is located in the threaded hole 3310a and is threadedly connected to the rotating shaft 331, so that the microphone rod 200 is fixedly connected to the rotating assembly 330, so that the microphone rod 200 and the rotating assembly 330 rotate synchronously.

[0066] It can be understood that in order to pre-fix the rotating shaft 331 and the mounting bracket 310 so that the fixing member 332 can be subsequently connected to the end of the rotating shaft 331 away from the second limit portion 3312, the gap between the rotating shaft 331 and the mounting bracket 310 is designed to be smaller. This makes it easier for the rotating shaft 331 to damage the wall of the rotating hole 311 when passing through the rotating hole 311, thereby reducing the rotation stability and smoothness of the rotating shaft 331 and the microphone rod 200.

[0067] For this reason, Figure 7 and Figure 8As shown, in one embodiment, there is a gap between the rotating shaft 331 and the hole wall of the rotating hole 311, the hole wall of the rotating hole 311 is provided with an annular groove 313, the rotating shaft 331 is provided with at least two mounting holes 3310b, and the at least two mounting holes 3310b are evenly spaced along the circumference of the rotating shaft 331, the rotating assembly 330 also includes at least two elastic telescopic parts 335, and the at least two elastic telescopic parts 335 are arranged in a one-to-one correspondence with the at least two mounting holes 3310b, each elastic telescopic part 335 is located in the corresponding mounting hole 3310b and is connected to the rotating shaft 331, and each elastic telescopic part 335 is also located in the annular groove 313 and is connected to the mounting frame 310. In this embodiment, when the rotating shaft 331 passes through the rotating hole 311, each elastic member 335 abuts against the rotating hole 311 and at least partially retracts into the corresponding mounting hole 3310b, thereby preventing the elastic member 335 from damaging the wall of the rotating hole 311. After the rotating shaft 331 enters the predetermined position, each elastic member 335 aligns with the annular groove 313 and extends into the annular groove 313, thereby connecting with the groove wall of the annular groove 313. When the rotating shaft 331 and the microphone rod 200 rotate, each elastic member 335 slides along the annular groove 313. Since each elastic member 335 at least partially retracts into the mounting hole 3310b when the rotating shaft 331 passes through the rotating hole 311, thereby preventing the elastic member 335 from damaging the wall of the rotating hole 311, dimensional stability and smoothness of rotation are ensured, thereby ensuring stable and smooth rotation of the rotating shaft 331 and the microphone rod 200.

[0068] In order to reduce the wear of the elastic expansion member 335 on the mounting frame 310 when the microphone rod 200 rotates, as shown in FIG. Figure 8 and Figure 9 As shown, in one embodiment, each elastic telescopic member 335 includes a spring 3351 and a rolling portion 3352, the spring 3351 of each elastic telescopic member 335 is installed in the corresponding mounting hole 3310b, the rolling portion 3352 of each elastic telescopic member 335 is located in the corresponding mounting hole 3310b and is connected to the corresponding spring 3351, and the rolling portion 3352 of each elastic telescopic member 335 is also located in the annular groove 313 and is rollingly connected to the mounting frame 310. In this embodiment, when the microphone rod 200 and the rotating shaft 331 rotate, the rolling portion 3352 of each elastic telescopic member 335 rolls along the groove wall of the annular groove 313, so that each elastic telescopic member 335 and the mounting frame 310 are in a rolling connection, thereby reducing the friction between each elastic telescopic member 335 and the mounting frame 310, reducing the wear of each elastic telescopic member 335 and the mounting frame 310, and thereby reducing the wear of the friction surface. At the same time, the smoothness of the friction surface is improved, thereby improving the rotation stability and smoothness of the microphone rod 200.

[0069] It can be understood that, since the rolling portion 3352 of each elastic telescopic member 335 rolls when the microphone rod 200 rotates, the rolling portion 3352 of each elastic telescopic member 335 and the spring 3351 rub against each other, and since the spring 3351 is relatively thin, the spring 3351 of each elastic telescopic member 335 is more likely to scratch the corresponding rolling portion 3352, thereby causing the rolling portion 3352 of each elastic telescopic member 335 to be severely worn, thereby causing the rolling portion 3352 of each elastic telescopic member 335 to be unable to continuously contact the groove wall of the annular groove 313, thereby reducing the rotation stability of the microphone rod 200. Moreover, since the rolling portion 3352 of each elastic telescopic member 335 is more likely to be scratched by the corresponding spring 3351, the smoothness of the rolling portion 3352 of each elastic telescopic member 335 is poor, thereby causing the microphone rod 200 to be more likely to jam when rotating, thereby causing the microphone rod 200 to have poor rotation smoothness. Therefore, if Figure 9 As shown, in one embodiment, each elastic telescopic member 335 also includes a receiving shell 3353, and the receiving shell 3353 of each elastic telescopic member 335 is fixedly connected to the first end of the corresponding spring 3351. The receiving shell 3353 of each elastic telescopic member 335 is provided with a receiving groove 3353a, and the receiving groove 3353a of the receiving shell 3353 of each elastic telescopic member 335 is adapted to the corresponding rolling portion 3352. The rolling portion 3352 of each elastic telescopic member 335 is located in the corresponding receiving groove 3353a and is rollingly connected to the corresponding receiving shell 3353, so that the rolling portion 3352 of each elastic telescopic member 335 is connected to the spring 3351 through the receiving shell 3353. In this embodiment, when the microphone rod 200 and the rotating shaft 331 rotate, the rolling portion 3352 of each elastic telescopic member 335 rolls simultaneously along the groove wall of the corresponding receiving groove 3353a of the receiving shell 3353 and the groove wall of the annular groove 313, thereby avoiding direct contact between the spring 3351 of each elastic telescopic member 335 and the corresponding rolling portion 3352, and thus avoiding the problem of the spring 3351 of each elastic telescopic member 335 scratching the rolling portion 3352, so that the rotation stability and smoothness of the microphone rod 200 are guaranteed.

[0070] like Figure 9 As shown, in one embodiment, each elastic telescopic part 335 also includes a mounting sleeve 3354, and the mounting sleeve 3354 of each elastic telescopic part 335 is located in the corresponding mounting hole 3310b and is sleeved with the rotating shaft 331, and the mounting sleeve 3354 of each elastic telescopic part 335 and the rotating shaft 331 are interference fit, so that the mounting sleeve 3354 of each elastic telescopic part 335 is fixedly connected to the corresponding mounting hole 3310b.

[0071] Furthermore, the mounting sleeve 3354 of each elastic telescopic part 335 is provided with a movable hole 3354a, and the spring 3351 of each elastic telescopic part 335 is installed in the movable hole 3354a, that is, the spring 3351 of each elastic telescopic part 335 is installed in the corresponding mounting hole 3310b through the corresponding movable hole 3354a, and the rolling part 3352 of each elastic telescopic part 335 is located in the mounting hole 3310b and is connected to the corresponding spring 3351.

[0072] Furthermore, each elastic telescopic part 335 also includes a limiting sleeve 3355, and the limiting sleeve 3355 of each elastic telescopic part 335 is located in the corresponding mounting hole 3310b and connected to one end of the corresponding mounting sleeve 3354. The limiting sleeve 3355 of each elastic telescopic part 335 is provided with a through hole, and the through hole of the limiting sleeve 3355 of each elastic telescopic part 335 is connected to the movable hole 3354a of the corresponding mounting sleeve 3354. The rolling portion 3352 of each elastic telescopic part 335 is passed through the corresponding through hole and abuts against the corresponding limiting sleeve 3355 to prevent the rolling portion 3352 of each elastic telescopic part 335 from deviating from the predetermined position, thereby ensuring the position stability of the rolling portion 3352 of each elastic telescopic part 335.

[0073] It is understandable that since the second connecting member 340 is a fastener and the second end of the second connecting member 340 is threadedly connected to the rotating shaft 331, when the microphone rod 200 rotates a certain number of times, the second connecting member 340 will become loose, thereby making the rotation stability of the microphone rod 200 poor. Figure 8 and Figure 9 As shown, in one embodiment, the mounting hole 3310b is connected to the threaded hole 3310a, and the outer wall of the second connecting member 340 is provided with a plurality of snap-in grooves 341, and each snap-in groove 341 is arranged in a one-to-one correspondence with the plurality of mounting holes 3310b. Each elastic and retractable member 335 also includes a snap-in portion 3356, which is located in the corresponding mounting hole 3310b and connected to the corresponding spring 3351. The snap-in portion 3356 of each elastic and retractable member 335 is also located in the corresponding snap-in groove 341 and snap-in to the second connecting member 340, so that the snap-in portion 3356 of each elastic and retractable member 335 limits the loosening of the second connecting member 340, thereby improving the rotational stability of the microphone rod 200.

[0074] like Figure 8 and Figure 9As shown, in this embodiment, the two ends of the spring 3351 of each elastic telescopic part 335 are respectively connected to the corresponding rolling part 3352 and the clamping part 3356, so that the spring 3351 of each elastic telescopic part 335 pushes the corresponding rolling part 3352 to be located in the annular groove 313, and the spring 3351 of each elastic telescopic part 335 also pushes the corresponding clamping part 3356 to be clamped in the corresponding clamping groove 341. When the second connecting member 340 is connected to the rotating shaft 331, the clamping portion 3356 of each elastic telescopic member 335 compresses the spring 3351 to prevent the clamping portion 3356 of each elastic telescopic member 335 from obstructing the threaded connection between the second connecting member 340 and the rotating shaft 331. When the second connecting member 340 is tightened, the multiple clamping grooves 341 of the second connecting member 340 are arranged in a one-to-one correspondence with the multiple clamping portions 3356, and the spring 3351 of each elastic telescopic member 335 pushes the corresponding clamping portion 3356 into the clamping groove 341 and clamps with the rotating shaft 331, that is, the spring 3351 of each elastic telescopic member 335 pushes the corresponding clamping portion 3356 to be clamped in the corresponding clamping groove 341, so that the clamping portion 3356 of each elastic telescopic member 335 limits the position of the second connecting member 340, thereby suppressing the loosening of the second connecting member 340, thereby improving the rotation stability of the microphone rod 200.

[0075] Furthermore, the clamping portion 3356 of each elastic telescopic member 335 is located in the movable hole 3354a and connected to the corresponding spring 3351 , so that the clamping portion 3356 of each elastic telescopic member 335 is located in the corresponding mounting hole 3310b and connected to the corresponding spring 3351 .

[0076] like Figure 9 As shown, in one embodiment, the clamping portion 3356 of each elastic and retractable member 335 is a spherical structure, and each clamping groove 341 of the rotating shaft 331 is adapted to the corresponding clamping portion 3356. In this embodiment, since the clamping portion 3356 of each elastic and retractable member 335 is a spherical structure, when the second connecting member 340 abuts the clamping portion 3356 of each elastic and retractable member 335, the second connecting member 340 can push the clamping portion 3356 of each elastic and retractable member 335 to compress the spring 3351, thereby preventing the clamping portion 3356 of each elastic and retractable member 335 from obstructing the threaded connection between the second connecting member 340 and the rotating shaft 331.

[0077] Compared with the prior art, the present invention has at least the following advantages:

[0078] 1. When the microphone rod 200 rotates, the rotating assembly 330 contacts the mounting bracket 310 and rotates relative to it, thereby preventing the microphone rod 200 from directly contacting the ear shell 100, thereby reducing wear on the microphone rod 200 and the ear shell 100, and avoiding the problem of powder loss on the microphone rod 200 and the ear shell 100.

[0079] 2. When the microphone rod 200 rotates, the rotating assembly 330 and the mounting frame 310 come into contact and rotate relative to each other, so that the friction surface is provided on the rotating assembly 330 and the mounting frame 310. Since both the rotating assembly 330 and the mounting frame 310 are wear-resistant structures, the wear of the friction surface is reduced, thereby improving the smoothness and stability of the rotation of the microphone rod 200.

[0080] 3. Due to the large volume of the ear shell 100 and the microphone stem 200, the manufacturing cost of the ear shell 100 and the microphone stem 200 has a greater impact on the manufacturing cost of the headphone 10. Since the ear shell 100 and the microphone stem 200 do not need to be in direct contact, the wear resistance of the ear shell 100 and the microphone stem 200 can be lower, thereby reducing the manufacturing cost of the ear shell 100 and the microphone stem 200, and further reducing the manufacturing cost of the headphone 10.

[0081] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
