Description
Technical Field
[0001] This application relates to the field of headphones, and more particularly to a noise reduction structure for a microphone 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 head and a microphone boom. The microphone head is fixedly connected to one end of the microphone boom to convert sound signals into electrical signals. The microphone boom has a connection hole through which a wire is threaded to allow the microphone boom to be bent, thereby adjusting the position of the microphone head and improving the usability of the microphone.
[0004] However, in practical applications, the wire is also threaded through the connection hole. When the microphone rod is bent, the wire is easy to flip, which increases the friction between the wire and the wire, resulting in louder microphone noise. Therefore, improvements are needed. Utility Model Content
[0005] In order to reduce microphone noise, firstly, this application provides a microphone noise reduction structure.
[0006] The noise reduction structure for a microphone provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, in practical applications, the microphone boom is fixed by bending a metal wire in the connecting hole, facilitating microphone position adjustment. Since one end of the metal wire is fixed to the mounting base, it minimizes the possibility of the wire shifting, effectively reducing friction between the wire and the power cord, thereby lowering microphone noise. Simultaneously, the connection between the microphone boom and the mounting base is more stable due to the metal wire connection.
[0009] Preferably, the cross-section of the connecting hole is elliptical.
[0010] By adopting the above technical solution and setting the cross-section of the connection hole to be elliptical, the distance between the metal wire and the wire can be increased, thereby further avoiding contact between the metal wire and the wire and reducing microphone noise.
[0011] Preferably, the outer side of the microphone rod is provided with a plurality of force-applying grooves, and the plurality of force-applying grooves are spaced apart along the length direction of the microphone rod.
[0012] By adopting the above technical solution, and by setting a force-applying groove to increase friction, it is easier to apply force to the microphone rod, thereby facilitating the bending of the microphone rod.
[0013] Preferably, the mounting base includes a housing and a mounting plate. A rotating groove is provided on one side of the housing, and multiple locking grooves are provided at intervals along its circumference on the other side.

The microphone rod is rotatably connected to the rotating groove, and the metal wire is disposed on the mounting plate.
[0014] By adopting the above technical solution, by setting up a housing and a mounting plate, rotating the microphone rod drives the mounting plate to rotate, so that the mounting plate is engaged with other locking slots, thereby realizing the adjustment of the microphone rod angle position, and further realizing the adjustment of the microphone position.
[0015] Preferably, the metal wire includes a deformable part and a fixed part. The deformable part is located in the connecting hole, one end of the fixed part is disposed in the deformable part, and the other end passes through the housing and the mounting plate and abuts against the side of the mounting plate away from the microphone rod.
[0016] By adopting the above technical solution, and by setting a deformable part and a fixed part, the deformable part is used for bending the microphone rod, and the fixed part is used to fix it to the mounting plate, thus facilitating the installation and disassembly of the microphone rod and the mounting base.
[0017] Preferably, the noise reduction structure further includes a first limiting block, which is disposed at one end of the connecting hole near the mounting base, and the metal wire is limited in the first limiting block.
[0018] By adopting the above technical solution and setting the first limiting block, the deformation of the metal wire can be limited, thereby preventing the metal wire from flipping over and further reducing the friction between the metal wire and the wire.
[0019] Preferably, the noise reduction structure further includes a limiting sleeve, which is sleeved on the metal wire and abuts against and limits the first limiting block.
[0020] By adopting the above technical solution and setting a limiting sleeve, the metal wire and the first limiting block are positioned and installed, thereby achieving the positioning and installation of the metal wire and the mounting base.
[0021] Preferably, the noise reduction structure further includes a second limiting block, which is located at the end of the connecting hole away from the mounting base, and the metal wire is confined within the second limiting block.
[0022] By adopting the above technical solution and setting a second limiting block, the deformation of the metal wire is further limited, thereby further preventing the metal wire from flipping over.
[0023] Preferably, the metal wire is an iron wire.
[0024] By adopting the above technical solution, and by setting the metal wire to iron wire, the iron wire has a certain deformation ability and low production cost.
[0025] Secondly, this application provides an earphone.

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0041] This application discloses a noise reduction structure for a microphone.
[0042] Example 1:
[0043] Reference Figure 1 The noise reduction structure includes a microphone rod 1, a mounting base 2, and a metal wire 3. One end of the microphone rod 1 is mounted on one side of the mounting base 2, and a connecting hole 11 is formed along the length of the microphone rod 1. The metal wire 3 is located in the connecting hole 11 to fix the microphone rod 1 after bending. Simultaneously, one end of the metal wire 3 extends to the mounting base 2, and the extended end of the metal wire 3 is fixedly connected to the mounting base 2. In this embodiment, the metal wire 3 is iron wire, which has a certain deformation capacity, low production cost, and strong performance. In other embodiments, the metal wire 3 can also be copper wire, aluminum wire, etc., and this application is not limited thereto.
[0044] In practical applications, the microphone boom 1 is fixed by bending the metal wire 3 in the connecting hole 11, facilitating the adjustment of the microphone head position connected to one end of the boom 1. Since one end of the metal wire 3 is fixed to the mounting base 2, the deformation range of the metal wire 3 is minimized, preventing it from shifting and effectively reducing friction between the metal wire 3 and the wire in the connecting hole 11, thereby reducing microphone noise. Simultaneously, the connection between the microphone boom 1 and the mounting base 2 is more stable, improving the stability of microphone use.
[0045] In some embodiments, the cross-section of the connecting hole 11 is elliptical, which allows for a greater distance between the metal wire 3 and the wire, thereby further preventing the metal wire 3 from contacting the wire and thus reducing microphone noise.
[0046] In some embodiments, a plurality of force-applying grooves 12 are provided on the outer side of the microphone rod 1. The force-applying grooves 12 are evenly spaced along the length direction of the microphone rod 1. When force is applied to bend the microphone rod 1, the friction with the microphone rod 1 can be increased, thereby facilitating the application of force to the microphone rod 1 and thus facilitating the bending of the microphone rod 1.
[0047] Reference Figure 1 and Figure 3 In some embodiments, the mounting base 2 includes a housing 21 and a mounting plate 22. A rotating groove 211 is provided on one side of the housing 21, and one end of the microphone rod 1 is rotatably connected to the rotating groove 211. Multiple locking slots 212 are provided on the other side of the housing 21, evenly spaced along the circumference of the housing 21. The mounting plate 22 is rotatably connected to the housing 21 and engages with the locking slots 212. The axis of rotation of the mounting plate 22 is collinear with the axis of rotation of the microphone rod 1. Simultaneously, a metal wire 3 is fixedly connected to the mounting plate 22 so that the microphone rod 1 and the mounting plate 22 rotate synchronously. By rotating the microphone rod 1, the mounting plate 22 is driven to rotate, causing the mounting plate 22 to engage with other locking slots, thereby adjusting the angle position of the microphone rod 1 and further adjusting the position of the microphone head.
[0048] Reference Figure 1 and Figure 4 In some embodiments, the metal wire 3 includes a deformable part 31 and a fixed part 32. The deformable part 31 is located in the connecting hole 11. One end of the fixed part 32 is integrally connected to the deformable part 31, and the other end is bent and passed through the housing 21 and the mounting plate 22 and abuts against the side of the mounting plate 22 away from the microphone rod 1. The structure is simple and facilitates the installation and disassembly of the microphone rod 1 and the mounting base 2.
[0049] The implementation principle of this embodiment is as follows: In practical applications, the microphone boom 1 is bent and fixed through the metal wire 3 in the connecting hole 11, so as to facilitate the adjustment of the microphone head position fixed to one end of the microphone boom 1. Since one end of the metal wire 3 is fixed to the mounting base 2, the deformation range of the metal wire 3 is reduced, minimizing the possibility of the metal wire 3 flipping over. This effectively reduces friction between the metal wire 3 and the wire in the connecting hole 11, thereby reducing microphone noise. Simultaneously, the connection between the microphone boom 1 and the mounting base 2 is more stable due to the connection of the metal wire 3, improving the stability of microphone use.
[0050] Example 2:
[0051] Reference Figure 5This embodiment is the same as the other structures in embodiment 1. The difference is that the noise reduction structure also includes a first limiting block 4. The first limiting block 4 is fixedly connected to the microphone rod 1 and located at the end of the connecting hole 11 near the mounting base 2. The end of the deformable part 31 near the fixed part 32 is limited in the first limiting block 4, which can limit the deformation of the metal wire 3, thereby preventing the metal wire 3 from flipping over and further reducing the friction between the metal wire 3 and the wire.
[0052] Reference Figure 5 and Figure 6 In some embodiments, the noise reduction structure further includes a limiting sleeve 5, which is fitted and fixed to the deformable part 31, and one end of the limiting sleeve 5 abuts against the limiting position of the first limiting block 4 to realize the positioning and installation of the metal wire 3 and the first limiting block 4, thereby realizing the positioning and installation of the metal wire 3 and the mounting base 2.
[0053] Referring to Figure 7, in some embodiments, the noise reduction structure further includes a second limiting block 6. The second limiting block 6 is fixedly connected to the microphone rod 1 and located at the end of the connecting hole 11 away from the mounting base 2. The end of the deformable part 31 away from the fixed part 32 is limited in the second limiting block 6, further limiting the deformation of the metal wire 3. By cooperating with the first limiting block 4 and the second limiting block 6, the effect of limiting the deformation of the deformable part 31 is greatly improved, thereby preventing the metal wire 3 from flipping over.
[0054] This application also discloses an earphone.
[0055] The headphones include the noise reduction structure described in the above embodiments.
[0056] 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.
