Description

Technical Field

[0001] This application relates to the field of headphones, and more particularly to a microphone angle adjustment mechanism and headphones. Background Technology

[0002] Over-ear headphones, also known as headphones worn on the head, are typically larger than earbuds or in-ear headphones and can completely or partially cover the user's ears. Some over-ear headphones also have microphones.

[0003] In related technologies, a microphone includes a microphone boom and a microphone head. The microphone head is fixedly connected to one end of the microphone boom, and the other end of the microphone boom is rotatably connected to the mounting shell of the earphone through a damping sleeve. The angle of the microphone can be adjusted by rotating the microphone boom.

[0004] However, in practical applications, after the headphones have been used for a period of time, the damping sleeve and the mounting shell are prone to loosening, making it difficult to fix the position of the microphone rod after it rotates. Therefore, improvements are needed. Utility Model Content

[0005] In order to ensure that the microphone boom remains fixed after prolonged use, this application provides a microphone angle adjustment mechanism.

[0006] The microphone angle adjustment mechanism provided in this application adopts the following technical solution:

[0007] A microphone angle adjustment mechanism includes a mounting shell, a microphone boom, and a limiting plate. A rotating groove is provided on one side of the mounting shell, and multiple limiting grooves are provided on the other side of the mounting shell, with the multiple limiting grooves spaced apart circumferentially around the mounting shell. One end of the microphone boom is rotatably connected to the rotating groove. The limiting plate includes a plate body and a limiting post. The plate body is located on one side of the microphone boom and is movably disposed within the mounting shell. The limiting post is located on the periphery of the plate body and is elastically engaged with the limiting groove.

[0008] By adopting the above technical solution, in practical applications, since one end of the microphone rod is rotatably connected to the rotating groove, by applying force to the microphone rod, the microphone rod and the mounting shell rotate relative to each other, and the microphone rod drives the disc to rotate, so that the limiting post is engaged in different limiting grooves, thereby achieving the fixation of the microphone rod after rotation. Its structure is simple and stable in use, and even after the headphones have been used for a long time, the fixation of the microphone rod after rotation can be guaranteed.

[0009] Preferably, the disc body is detachably connected to the microphone rod.

[0010] By adopting the above technical solution, the disc body is detachably connected to the microphone rod, so as to facilitate the assembly of the mounting shell, the microphone rod and the limiting disc.

[0011] Preferably, the angle adjustment mechanism further includes an elastic lever, one end of which is disposed on the microphone rod, and the other end passes through the mounting shell and the disc body and elastically abuts against the side of the disc body away from the microphone rod.

[0012] By adopting the above technical solution and setting an elastic lever, a detachable connection between the disc body and the microphone rod can be achieved. The structure is simple and easy to operate, which facilitates the installation and disassembly of the disc body and the microphone rod.

[0013] Preferably, the disc body has multiple positioning holes on the side near the microphone rod, and the microphone rod is movably inserted through the mounting shell and plugged into each of the positioning holes.

[0014] By adopting the above technical solution and setting multiple positioning holes, the positioning and installation between the disc body and the microphone rod can be achieved, thereby improving the accuracy of installation.

[0015] Preferably, the mounting housing has two limiting blocks on the side away from the microphone rod, and the limiting plate also includes an abutment block, which is located on the periphery of the plate and is used to abut against the side of the two limiting blocks that are far apart from each other.

[0016] By adopting the above technical solution and setting two limiting blocks, when the abutting block abuts against the limiting block, the disk body can be restricted from continuing to rotate, thereby limiting the excessive rotation of the microphone boom and giving the microphone a reasonable angle adjustment range to improve the usability of the microphone.

[0017] Preferably, there are two limiting posts, which are spaced apart circumferentially along the disc body.

[0018] By adopting the above technical solution and setting two limiting posts, the stability of the microphone rod after rotation is improved.

[0019] Preferably, the limiting plate further includes a connecting block, which is disposed between the plate body and the limiting post.

[0020] By adopting the above technical solution and setting a connecting block, the stability of the connection between the disc and the limiting post is improved, and the limiting post can be guaranteed to have a certain elastic deformation capacity so as to facilitate the rotation of the lever.

[0021] Secondly, this application provides an earphone.

[0022] The earphone provided in this application adopts the following technical solution:

[0023] An earphone, comprising the angle adjustment mechanism described above.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. In practical applications, since one end of the microphone rod is rotatably connected to the rotating groove, by applying force to the microphone rod, the microphone rod and the mounting shell rotate relative to each other, and the microphone rod drives the disc to rotate, so that the limiting post is engaged in different limiting grooves to achieve the fixation of the microphone rod after rotation. Its structure is simple and stable in use. Even after the headphones have been used for a long time, the fixation of the microphone rod after rotation can be guaranteed.

[0026] 2. By setting an elastic locking rod, a detachable connection between the disc body and the microphone rod can be achieved. The structure is simple and easy to operate, which facilitates the installation and removal of the disc body and the microphone rod.

[0027] 3. By setting two limit blocks, when the abutment block abuts against the limit block, the plate can be restricted from continuing to rotate, thereby limiting the excessive rotation of the microphone boom and giving the microphone a reasonable angle adjustment range to improve the usability of the microphone.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0035] This application discloses a microphone angle adjustment mechanism.

[0036] Reference Figure 1 and Figure 2 The angle adjustment mechanism includes a mounting shell 1, a microphone rod 2, and a limiting plate 3. The mounting shell 1 is round. One side of the mounting shell 1 has a rotating groove 11 and a through movable groove 12. The other side of the mounting shell 1 has multiple limiting grooves 13. The multiple limiting grooves 13 are evenly spaced along the circumference of the mounting shell 1.

[0037] One end of the microphone lever 2 is rotatably connected to the rotating groove 11, and the limiting disc 3 includes a disc body 31 and a limiting post 32. The disc body 31 is installed on the side of the microphone lever 2 near the mounting shell 1 through the movable groove 12 and is movably disposed in the mounting shell 1 so as to rotate with the microphone lever 2. The limiting post 32 is integrally connected to the periphery of the disc body 31, and the limiting post 32 is elastically engaged in one of the limiting grooves 13 to restrict the rotation of the disc body 31.

[0038] In practical applications, since one end of the microphone rod 2 is rotatably connected to the rotating groove 11, by applying force to the microphone rod 2, the microphone rod 2 and the mounting shell 1 rotate relative to each other, and the microphone rod 2 drives the disc body 31 to rotate synchronously. The limiting post 32 undergoes elastic deformation and disengages from the limiting groove 13. After the rotation stops, the limiting post 32 restores its deformation and is locked into another limiting groove 13 to achieve the fixation of the microphone rod 2 after rotation. Its structure is simple and stable in use. Even after the headphones have been used for a long time, the fixation of the microphone rod 2 after rotation can be guaranteed.

[0039] In some embodiments, the disc body 31 is detachably connected to the microphone rod 2. When installing the angle adjustment mechanism, one end of the microphone rod 2 is first installed in the rotating groove 11, and then the disc body 31 is installed on the microphone rod 2. This facilitates the assembly of the mounting shell 1, the microphone rod 2, and the limiting disc 3. At the same time, when the elasticity of the limiting post 32 is insufficient, the limiting disc 3 can be replaced separately to reduce maintenance costs.

[0040] Reference Figure 1In some embodiments, the angle adjustment mechanism further includes an elastic lever 4. One end of the elastic lever 4 is fixedly connected to the microphone rod 2, and the other end is L-shaped, allowing the elastic lever 4 to pass through the movable slot 12 and the disc body 31 and elastically abut against the side of the disc body 31 away from the microphone rod 2, thereby achieving a detachable connection between the disc body 31 and the microphone rod 2. Simultaneously, the detachable connection between the two is achieved by the elastic lever 4 abutting against the disc body 31, resulting in a simple structure and convenient operation, thus facilitating the installation and disassembly of the disc body 31 and the microphone rod 2.

[0041] Reference Figure 2 In some embodiments, the portion of the disc body 31 near the microphone rod 2 extends into the movable groove 12 and has multiple positioning holes 33. The microphone rod 2 passes through the movable groove 12 into the mounting shell 1 and is inserted into each positioning hole 33 to achieve positioning installation between the disc body 31 and the microphone rod 2, thereby improving the accuracy of installation.

[0042] Reference Figure 1 In some embodiments, two limiting blocks 14 protrude from the side of the mounting shell 1 away from the microphone rod 2. At the same time, the limiting plate 3 also includes an abutment block 34, which is integrally connected to the periphery of the plate body 31. The abutment block 34 can abut against the side of the two limiting blocks 14 that are far apart from each other to limit the rotation of the plate body 31, thereby limiting the excessive rotation of the microphone rod 2, so that the microphone of the headset has a reasonable angle adjustment range to improve the usability of the microphone.

[0043] In some embodiments, there are two limiting posts 32, which are spaced apart along the circumference of the disc body 31. By engaging the two limiting posts 32 with the other two, the stability of the microphone rod 2 after rotation can be effectively improved.

[0044] In some embodiments, the limiting disk 3 further includes connecting blocks 35. The number of connecting blocks 35 matches the number of limiting posts 32. Each connecting block 35 is integrally connected between the disk body 31 and each limiting post 32. Since the limiting post 32 is cylindrical, the connecting blocks 35 can increase the connection area with the disk body 31, thereby improving the stability of the connection between the disk body 31 and the limiting post 32, and ensuring that the limiting post 32 has a certain elastic deformation capability so as to facilitate the rotation of the microphone 2.

[0045] The implementation principle of this embodiment is as follows: In practical application, since one end of the microphone rod 2 is rotatably connected to the rotating groove 11, by applying force to the microphone rod 2, the microphone rod 2 and the mounting shell 1 rotate relative to each other, and the microphone rod 2 drives the disc body 31 to rotate synchronously. The limiting post 32 undergoes elastic deformation and disengages from the limiting groove 13. After the rotation stops, the limiting post 32 restores its deformation and is engaged in another limiting groove 13 to achieve the fixation of the microphone rod 2 after rotation. Its structure is simple and stable in use. Even after the headphones have been used for a long time, the fixation of the microphone rod 2 after rotation can be guaranteed.

[0046] This application also discloses an earphone.

[0047] Reference Figure 3 The headphones include a headband 5 and an angle adjustment mechanism as described in the above embodiments, with the headband 5 fixedly connected to the mounting housing 1.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
