In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.

[0037] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] As Figure 1 shown, an ear fork assembly provided by an embodiment of the present utility model can be applied to a head-mounted earphone and is used to connect a headband assembly and a sound generating unit. Among them, the head-mounted earphone can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function. At the same time, it can also be configured with functions such as stereo surround.

[0039] Combined Figure 2 with Figure 3 , the ear fork assembly includes an ear fork 100, a sliding arm 200, a wear-resistant sheet 300, and an elastic anti-slip strip 400.

[0040] The ear fork 100 includes a sliding arm connection portion 110 and a sound generating unit mounting portion 120 connected to the end of the sliding arm connection portion 110. The sliding arm connection portion 110 is provided with a sliding channel 111, and the sliding channel 111 penetrates through one end of the sliding arm connection portion 110 away from the sound generating unit mounting portion 120. The sliding arm 200 is slidably inserted into the sliding channel 111. One end of the sliding arm 200 faces the sound generating unit mounting portion 120, and the other end is used to connect the headband assembly. The sound generating unit mounting portion 120 is used to mount the sound generating unit.

[0041] It can be understood that by pulling the ear fork 100, the ear fork 100 can slide relative to the sliding arm 200 to move the sound generating unit mounting portion 120 towards or away from the sliding arm 200, thereby realizing the adjustment of the position of the sound generating unit.

[0042] The wear-resistant piece 300 and the elastic anti-slip strip 400 are both arranged in the sliding channel 111, and the wear-resistant piece 300 and the elastic anti-slip strip 400 respectively abut against the two side walls of the sliding arm 200 arranged along the thickness direction of the sliding arm 200.

[0043] Specifically, the wear-resistant piece 300 and the elastic anti-slip strip 400 are arranged at intervals along the thickness direction of the sliding arm 200. The sliding arm 200 has two side walls arranged opposite to each other along its thickness direction. The wear-resistant piece 300 and the elastic anti-slip strip 400 respectively abut against these two side walls. When the ear fork 100 slides relative to the sliding arm 200, sliding friction is generated between the two side walls of the sliding arm 200 and the wear-resistant piece 300 and the elastic anti-slip strip 400 respectively.

[0044] Among them, the material of the wear-resistant piece 300 can be Teflon, and the material of the elastic anti-slip strip 400 can be silica gel.

[0045] As Figures 2 to 5 shown, in the ear fork assembly of the present utility model, one end of the sliding arm 200 away from the sound generating unit mounting portion 120 is used to connect the headband assembly, and the sound generating unit mounting portion 120 is used to mount the sound generating unit. By pulling the ear fork 100, the ear fork 100 can slide relative to the sliding arm 200 to move the sound generating unit mounting portion 120 towards or away from the sliding arm 200, thereby realizing the adjustment of the position of the sound generating unit. And when the ear fork 100 slides relative to the sliding arm 200, sliding friction is generated between the two side walls of the sliding arm 200 and the wear-resistant piece 300 and the elastic anti-slip strip 400 respectively, thereby generating a sense of damping to ensure the feel. In addition, when the position of the sound generating unit is not adjusted, under the abutting action of the elastic anti-slip strip 400, the sliding arm 200 and the wear-resistant piece 300 also abut against each other, which can reduce the risk of relative sliding between the ear fork 100 and the sliding arm 200 and improve the problem of random movement of the position of the sound generating unit.

[0046] It should be noted that even when the wear-resistant piece 300 and / or the sliding arm 200 are worn due to the relative sliding between the ear fork 100 and the sliding arm 200, under the elastic extrusion action of the elastic anti-slip strip 400, it can also ensure that the sliding arm 200 and the wear-resistant piece 300 are closely attached together, reducing the risk of loosening of the sliding arm 200.

[0047] Furthermore, there are multiple wear-resistant pieces 300, and the multiple wear-resistant pieces 300 are arranged at intervals along the width direction of the sliding arm 200 and jointly abut against the sliding arm 200.

[0048] Furthermore, there are multiple elastic anti-slip strips 400. The multiple elastic anti-slip strips 400 are arranged at intervals along the width direction of the sliding arm 200 and jointly abut against the sliding arm 200.

[0049] It can be understood that by arranging multiple wear-resistant pieces 300 and multiple elastic anti-slip strips 400 to jointly abut against the sliding arm 200, the force on the sliding arm 200 can be made more uniform, thereby improving the smoothness when the ear fork 100 slides with the sliding arm 200.

[0050] Specifically, in this embodiment, the number of wear-resistant pieces 300 is two, and the number of elastic anti-slip strips 400 is also two.

[0051] As Figure 3 shown, it should be noted that a first positioning groove 112 is provided on the inner wall of the sliding channel 111. The first positioning groove 112 and the sliding arm 200 are arranged along the thickness direction of the sliding arm 200. The first positioning groove 112 and the elastic anti-slip strip 400 are respectively located on both sides of the sliding arm 200 along the thickness direction of the sliding arm. The notch of the first positioning groove 112 faces the sliding arm 200. The wear-resistant piece 300 is arranged in the first positioning groove 112, and at least part of the wear-resistant piece 300 protrudes from the notch of the first positioning groove 112.

[0052] Furthermore, a second positioning groove 113 is provided on the inner wall of the sliding channel 111. The second positioning groove 113 and the sliding arm 200 are arranged along the thickness direction of the sliding arm 200. The second positioning groove 113 and the wear-resistant piece 300 are respectively located on both sides of the sliding arm 200 along the thickness direction of the sliding arm. The notch of the second positioning groove 113 faces the sliding arm 200. The elastic anti-slip strip 400 is arranged in the second positioning groove 113, and at least part of the elastic anti-slip strip 400 protrudes from the notch of the second positioning groove 113.

[0053] Specifically, in this embodiment, the first positioning groove 112 and the second positioning groove 113 are respectively located on both sides of the sliding arm 200 along the thickness direction of the sliding arm 200. The notches of the first positioning groove 112 and the second positioning groove 113 both face the sliding arm 200. The wear-resistant piece 300 is arranged in the first positioning groove 112, and at least part of the wear-resistant piece 300 protrudes from the notch of the first positioning groove 112. The elastic anti-slip strip 400 is arranged in the second positioning groove 113, and at least part of the elastic anti-slip strip 400 protrudes from the notch of the second positioning groove 113.

[0054] It can be understood that the first positioning groove 112 is used for installing the wear-resistant sheet 300 and positioning the wear-resistant sheet 300, and the second positioning groove 113 is used for installing the elastic anti-slip strip 400 and positioning the elastic anti-slip strip 400; in addition, the first positioning groove 112 can also limit the wear-resistant sheet 300 to prevent the wear-resistant sheet 300 from moving in the width direction of the sliding arm 200, and the second positioning groove 113 can also limit the elastic anti-slip strip 400 to prevent the elastic anti-slip strip 400 from moving in the width direction of the sliding arm 200.

[0055] It should be noted that the wear-resistant sheet 300 and / or the elastic anti-slip strip 400 can be pasted in the sliding channel 111 by using double-sided tape or glue.

[0056] In some embodiments, a first relief opening is provided on the side wall of the first positioning groove 112, and at least a part of the wear-resistant sheet 300 is disposed opposite to the first relief opening.

[0057] It can be understood that when the wear-resistant sheet 300 needs to be replaced, or when the installation position of the wear-resistant sheet 300 is inaccurate and needs to be removed and reinstalled, the hand of the assembler can touch the wear-resistant sheet 300 through the first relief opening, which is convenient for pulling out the wear-resistant sheet 300.

[0058] Furthermore, the wear-resistant sheet 300 has a first handle position extending into the first relief opening.

[0059] It can be understood that the first handle position is convenient for the assembler to hold the wear-resistant sheet 300 with the hand, so as to pull out the wear-resistant sheet 300 from the first positioning groove 112. In addition, the first handle position also plays an anti-fooling role, which can prevent the wear-resistant sheet 300 from being installed reversely.

[0060] As Figure 6 、 Figure 7 shown, furthermore, a second relief opening 1131 is provided on the side wall of the second positioning groove 113, and at least a part of the elastic anti-slip strip 400 is disposed opposite to the second relief opening 1131.

[0061] It can be understood that when the elastic anti-slip strip 400 needs to be replaced, or when the installation position of the elastic anti-slip strip 400 is inaccurate and needs to be removed and reinstalled, the hand of the assembler can touch the elastic anti-slip strip 400 through the second relief opening 1131, which is convenient for pulling out the elastic anti-slip strip 400.

[0062] Even further, the elastic anti-slip strip 400 has a second handle position 410 extending into the second relief opening 1131.

[0063] It can be understood that the second finger-holding position 410 facilitates the assembler to hold the elastic anti-slip strip 400 with the hand, so as to pull out the elastic anti-slip strip 400 from the second positioning groove 113. In addition, the second finger-holding position 410 also plays an anti-mistake role and can prevent the elastic anti-slip strip 400 from being installed in the wrong direction.

[0064] Combined with Figure 4 and Figure 5 , in some embodiments, the ear fork 100 includes an ear fork body 101 and a cover body 102. The cover body 102 is covered on the ear fork body 101. The cover body 102 and the ear fork body 101 jointly define a sliding channel 111. The wear-resistant sheet 300 is arranged in a first positioning groove 112 located on the inner side of the cover body 102, and the elastic anti-slip strip 400 is arranged in a second positioning groove 113 located on the inner side of the ear fork body 101.

[0065] As Figure 5 shown, in some embodiments, the opening of the sliding channel 111 is formed at one end of the sliding arm connecting portion 110 away from the sound generating unit mounting portion 120. A first anti-detachment portion 1111 is arranged at the opening. A second anti-detachment portion 210 is provided at one end of the sliding arm 200 close to the sound generating unit mounting portion 120. The first anti-detachment portion 1111 is located on the sliding path of the second anti-detachment portion 210. In this way, the sliding arm 200 can be prevented from sliding out of the sliding channel 111.

[0066] The present utility model further provides a headphone, including the ear fork assembly as in the above embodiments.

[0067] The headphone of the present utility model has the ear fork assembly of the above embodiments. In the ear fork assembly, one end of the sliding arm 200 away from the sound generating unit mounting portion 120 is used to connect to the headband assembly, and the sound generating unit mounting portion 120 is used to mount the sound generating unit. By pulling the ear fork 100, the ear fork 100 and the sliding arm 200 can slide relative to each other so that the sound generating unit mounting portion 120 moves towards or away from the sliding arm 200, thereby realizing the adjustment of the position of the sound generating unit. And when the ear fork 100 and the sliding arm 200 slide relative to each other, sliding friction is generated between the two side walls of the sliding arm 200 and the wear-resistant sheet 300 and the elastic anti-slip strip 400 respectively, thereby generating a damping feeling and ensuring the hand feeling. In addition, when the position of the sound generating unit is not adjusted, under the abutting action of the elastic anti-slip strip 400, the sliding arm 200 and the wear-resistant sheet 300 also abut against each other, which can reduce the risk of relative sliding between the ear fork 100 and the sliding arm 200 and improve the problem of random movement of the position of the sound generating unit. It should be noted that even when the wear-resistant sheet 300 and / or the sliding arm 200 are worn due to the relative sliding between the ear fork 100 and the sliding arm 200, under the elastic extrusion action of the elastic anti-slip strip 400, it can also ensure that the sliding arm 200 and the wear-resistant sheet 300 are closely attached together, reducing the risk of loosening of the sliding arm 200.
