[0001] The utility model relates to the technical field of earphones, in particular to a wireless earphone with an acoustic noise reduction structure. Background Art

[0002] The existing Chinese patent with the application number 202223445575.3 discloses an intelligent noise reduction wireless earphone, including an intelligent noise reduction wireless earphone body. There are two intelligent noise reduction wireless earphone bodies. A noise reduction earplug is sleeved on the inner side of the intelligent noise reduction wireless earphone body. A mounting bracket is rotatably connected to the side of the intelligent noise reduction wireless earphone body. An installation block is installed at the upper end of the mounting bracket. The upper end of the installation block is fixedly connected with a mounting plate. One end of the mounting plate is fixedly connected with the upper end of another installation block. A lead screw is penetrated and threadedly connected in the mounting plate. The lower end of the lead screw is rotatably connected with an arc-shaped plate.

[0003] When the above technology is used, although it has a certain degree of wearing stability, since it only sets an arc-shaped plate at the top of the head, that is, the arc-shaped plate moves longitudinally and cannot rotate, and the head shapes of wearing personnel are various, so when the above is actually used, the adaptability of the earphone is poor. Therefore, in order to solve the above technical problems, we propose a wireless earphone with an acoustic noise reduction structure. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a wireless earphone with an acoustic noise reduction structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A wireless earphone with an acoustic noise reduction structure includes two wireless earphone bodies with noise reduction effects and a connecting plate for connecting the wireless earphone bodies. An abutting plate for contacting the head top of the wearing person is arranged on the inner side of the connecting plate. A spring piece is arranged at the rear side of the abutting plate. Insertion holes are arranged at both ends of the spring piece. A travel groove is arranged inside the connecting plate corresponding to the end of the spring piece. The end of the spring piece is located in the travel groove and is provided with a connecting column through the insertion hole. An inverted T-shaped locking cylinder is sleeved on the upper end of the connecting column. A top spring is jointly arranged between the inside of the locking cylinder and the connecting column. The upper end of the locking cylinder extends to the outside of the connecting plate. A plurality of matching limiting grooves are arranged on the inner wall of the travel groove of the connecting plate corresponding to the lower end of the locking cylinder.

[0007] Preferably, an elastic pad is arranged on the front side of the abutting plate, and the elastic pad is connected to the abutting plate through a magic tape.

[0008] Preferably, a limiting frame is fixed on the rear side of the abutting plate, and the middle part of the sheet body of the spring piece is penetrated between the limiting frame and the abutting plate.

[0009] Preferably, a plurality of matching identification grooves are provided on the front side of the connecting plate corresponding to the locking cylinder, and a color coating is provided inside the identification grooves.

[0010] Preferably, a pressing block is fixed at one end of the locking cylinder extending outside the connecting plate, and a beautifying sticker is provided on the front surface of the pressing block.

[0011] Preferably, the edge of the pressing block is rounded, and a matching accommodation hole for the top spring is provided inside the connecting column.

[0012] Preferably, a guiding groove is provided on one side of the inner travel groove of the connecting plate away from the locking cylinder, and a matching limiting protrusion is provided at the end of the connecting column corresponding to the guiding groove.

[0013] A wireless earphone with an acoustic noise reduction structure proposed by the present utility model has the following beneficial effects:

[0014] 1: In the present utility model, a person can press the pressing block, that is, the pressing block pushes the locking cylinder to move inside the travel groove until the end of the locking cylinder disengages from the limiting groove. At this time, the person can freely move the locking cylinder. During this process, when the ends of the elastic pieces approach each other, the middle of the elastic pieces bulges, that is, the middle of the elastic pieces pushes the contact plate closer to the top of the person's head, thereby achieving the effect of adjusting the position of the contact plate. Compared with the traditional solution, there is no lead screw directly exposed to the outside in this solution, which not only improves the aesthetics of the earphone, but also the person can move the two locking cylinders, so that the contact plate can be not only located in the middle of the earphone, that is, in the middle of the person's head, but also on the side of the earphone, that is, on one side of the person's head, thereby realizing the left and right movement of the contact plate, that is, to a certain extent, improving the adaptability of the earphone.

[0015] 2: In the present utility model, the setting of the elastic pad makes the contact plate not directly contact the top of the head of the earphone wearer. Therefore, when the earphone improves the stability through the direct contact between the contact plate and the head, the discomfort caused by the contact plate to the person's head is weakened, that is, the comfort of the earphone during use is improved; the setting of the limiting frame makes the connection between the elastic piece and the contact plate an insertion connection, which is convenient for the person to replace the contact plate or the elastic piece conveniently; the setting of the identification groove is convenient for the person to determine the bending amplitude of the elastic piece, and is also convenient for the person to position and remember the position of the locking cylinder, so that after the earphone is used by others, the owner of the earphone can quickly reset the contact plate; the setting of the pressing block is convenient for increasing the contact area between the person's finger and the locking cylinder, that is, it is convenient to avoid the phenomenon that the person's finger is uncomfortable due to the small force-bearing area when pressing the locking cylinder. At the same time, the setting of the beautifying sticker also makes the earphone beautiful during use, so as to improve the marketability of the earphone. Description of the Drawings

[0025] Refer toFigure 1-6 , under the condition that other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 lies in that:

[0026] An elastic pad 9 is provided on the front side of the contact plate 3. The elastic pad 9 is connected to the contact plate 3 through a magic tape. The setting of the elastic pad 9 makes the contact plate 3 not directly contact the head of the person wearing the earphone. Furthermore, when the earphone improves its stability by directly contacting the head through the contact plate 3, the discomfort caused by the contact plate 3 to the person's head is weakened, that is, the comfort of using the earphone is improved; A limiting frame 10 is fixed on the rear side of the contact plate 3. The middle part of the sheet body of the elastic piece 4 is inserted between the limiting frame 10 and the contact plate 3. The setting of the limiting frame 10 makes the elastic piece 4 and the contact plate 3 in an inserted connection, that is, it is convenient for personnel to replace the contact plate 3 or the elastic piece 4 conveniently; A number of matching identification grooves 11 are provided on the front side of the connecting plate 2 corresponding to the locking cylinder 6. A color coating is provided inside the identification grooves 11.

The setting of the guiding groove and the limiting protrusion 14 is convenient for guiding and limiting the connecting column 5, so that when the personnel drives the connecting column 3 to move through the locking cylinder 6, the connecting column 3 can move more smoothly.

[0028] Principle of use and advantages: In the process of using this utility model, the wireless earphone main body 1 is prior art. Therefore, during use, the wireless earphone main body 1 with noise reduction effect can provide noise reduction effect when playing audio. At the same time, after the earphones are worn, both ends of the earphones are clamped on the ears on both sides of the user's head through the wireless earphone main body 1. Subsequently, the contact plate 3 abuts against the top of the user's head through the elastic pad 9. Thus, the earphones can have good stability under the action of the contact plate 3. Further, when the position of the contact plate 3 needs to be adjusted due to different head shapes of the users, the user can press the pressing block 12, that is, the pressing block 12 pushes the locking cylinder 6 to move into the travel groove until the end of the locking cylinder 6 disengages from the limiting groove 8. At this time, the user can freely move the locking cylinder 6. During this process, when the ends of the elastic pieces 4 approach each other, the middle part of the elastic pieces 4 bulges, that is, the middle part of the elastic pieces 4 pushes the contact plate 3 closer to the top of the user's head, thereby realizing the effect of adjusting the position of the contact plate 3.

[0029] It should be further noted that the setting of the elastic pad 9 makes the contact plate 3 not directly contact the top of the head of the earphone wearer. Therefore, when the earphones improve stability through the direct contact between the contact plate 3 and the top of the head, the discomfort caused by the contact plate 3 to the top of the user's head is weakened, that is, the comfort of the earphones during use is improved; the setting of the limiting frame 10 makes the elastic pieces 4 and the contact plate 3 inserted and connected, which is convenient for the user to replace the contact plate 3 or the elastic pieces 4 conveniently; the setting of the marking groove 11 is convenient for the user to determine the bending amplitude of the elastic pieces 4, and is also convenient for the user to position and remember the position of the locking cylinder 6, so that after the earphones are used by others, the owner of the earphones can quickly reset the contact plate 3; the setting of the pressing block 12 is convenient for increasing the contact area between the user's finger and the locking cylinder 6, that is, it is convenient to avoid the phenomenon that the user's finger is uncomfortable due to the small force-bearing area when pressing the locking cylinder 6. At the same time, the setting of the beautifying sticker 13 also makes the earphones beautiful during use, so as to improve the appearance of the earphones; the setting of the guiding groove and the limiting protrusion 14 is convenient for guiding and limiting the connecting column 5, so that when the user drives the connecting column 3 to move through the locking cylinder 6, the connecting column 3 can move smoothly.

[0030] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
