[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] like Figure 1 As shown, the utility model provides a headset, wherein the headset can be a smart headset, and the headset can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and can also be configured with stereo surround and other functions. The headset includes a slide arm assembly 100, a headband assembly 200 and a sound unit 300, one end of the slide arm assembly 100 is connected to the headband assembly 200, and the other end is connected to the sound unit 300.

[0035] It can be understood that the number of the slide arm assembly 100 and the number of the sound unit 300 are both two, the two slide arm assemblies 100 are respectively connected to the two ends of the headband assembly 200, and the two sound units 300 are respectively connected to the two slide arms 110. The distance between the sound unit 300 and the headband assembly 200 can be adjusted by sliding the slide arm assembly 100, and the sound unit 300 is the main body of the earphone, which is used to generate sound.

[0036] Combination Figure 2 and Figure 3 The slide arm assembly 100 includes a slide arm 110 and a connecting arm 120 .

[0037] The sliding arm 110 is provided with a sliding channel 111 , and a first magnetic member 130 is installed on a side wall of the sliding channel 111 .

[0038] It can be understood that the slide arm 110 is a hollow structure with a sliding channel 111, and the sliding channel 111 runs through both ends of the slide arm 110, wherein the side wall of the sliding channel 111 is installed with a first magnetic component 130, that is, the first magnetic component 130 is installed on the inner wall of the slide arm 110.

[0039] The connecting arm 120 extends into the sliding channel 111 , and one end of the connecting arm 120 extends out of the sliding channel 111 and is connected to the headband assembly 200 , wherein the sliding arm 110 can slide relative to the connecting arm 120 .

[0040] It can be understood that one end of the connecting arm 120 is connected to the end of the headband assembly 200, and the other end of the connecting arm 120 extends into the sliding channel 111 of the sliding arm 110, wherein the sliding arm 110 can slide relative to the connecting arm 120, thereby approaching or moving away from the headband assembly 200.

[0041] Furthermore, a second magnetic member 140 is disposed on a side of the connecting arm 120 facing away from the first magnetic member 130 , and the second magnetic member 140 maintains magnetic attraction and cooperation with the first magnetic member 130 when the sliding arm 110 slides relative to the connecting arm 120 .

[0042] It is understandable that when the slide arm 110 slides relative to the connecting arm 120 to approach the headband assembly 200 or move away from the headband assembly 200, the first magnetic member 130 and the second magnetic member 140 maintain mutual attraction, so that when the user slides the slide arm 110, the damping effect can be felt, and the slide arm 110 is stable and smooth during the sliding process, thereby improving the user experience. In addition, when the user stops sliding the slide arm 110, the first magnetic member 130 and the second magnetic member 140 can also be used to position the slide arm 110 due to the mutual attraction between them.

[0043] It should be noted that one of the first magnetic member 130 and the second magnetic member 140 is a magnet, and the other is a magnet or an iron member. In this way, it can be ensured that there is an attractive force between the first magnetic member 130 and the second magnetic member 140.

[0044] It should be further explained that, in the process of the sliding arm 110 sliding relative to the connecting arm 120 to approach the headband assembly 200 or move away from the headband assembly 200, the first magnetic member 130 always remains opposite to the second magnetic member 140. This ensures that no matter where the sliding arm 110 slides to, the attraction between the first magnetic member 130 and the second magnetic member 140 does not change significantly, thereby ensuring that the sliding arm 110 is stable and smooth during the sliding process.

[0045] Specifically, the position where the slide arm 110 is closest to the headband assembly 200 is defined as the first position, and the position where the slide arm 110 is farthest from the headband assembly 200 is defined as the second position. When the slide arm 110 is in the first position, the first magnetic member 130 is opposite to the end of the second magnetic member 140 close to the headband assembly 200; when the slide arm 110 is in the second position, the first magnetic member 130 is opposite to the end of the second magnetic member 140 far from the headband assembly 200. In the process of the slide arm 110 moving back and forth between the first position and the second position, the first magnetic member 130 remains opposite to the second magnetic member 140.

[0046] Combination Figure 3 and Figure 4 In some embodiments, an extreme position limiting portion 121 is provided on the side of the connecting arm 120 facing away from the second magnetic member 140, and a limiting protrusion 112 is provided on the side wall of the sliding channel 111. The limiting protrusion 112 is located on the side of the connecting arm 120 away from the second magnetic member 140, and the extreme position limiting portion 121 is located on the moving path of the limiting protrusion 112 when it moves along the back of the headband assembly 200.

[0047] It can be understood that when the slide arm 110 moves to abut against the headband assembly 200, the slide arm 110 is in the first position, and when the slide arm 110 moves to abut against the limit position limit portion 121, the slide arm 110 is in the second position. Through the cooperation between the limit position limit portion 121 and the limit protrusion 112, the risk of the slide arm 110 slipping off the connecting arm 120 can be reduced. In addition, the limit position limit portion 121 is located on the side of the connecting arm 120 facing away from the second magnetic member 140, and the limit protrusion 112 is located on the side of the connecting arm 120 away from the second magnetic member 140. When the slide arm 110 slides relative to the connecting arm 120, the limit protrusion 112 will not contact the second magnetic member 140, and will not cause wear to the second magnetic member 140.

[0048] In some embodiments, the extreme position limiting portion 121 is integrally formed on the connecting arm 120, and the limiting protrusion 112 is integrally formed on the sliding arm 110; of course, in other embodiments, the extreme position limiting portion 121 can also be fixed to the connecting arm 120 in other ways, and the limiting protrusion 112 can also be fixed to the sliding arm 110 in other ways.

[0049] It should be noted that the limit protrusion 112 is spaced apart from the connecting arm 120, and the extreme position limit portion 121 is also spaced apart from the sliding arm 110. In this way, when the sliding arm 110 slides relative to the connecting arm 120, the limit protrusion 112 will not directly contact the connecting arm 120, and the extreme position limit portion 121 will not directly contact the sliding arm 110, thereby reducing the risk of wear.

[0050] Furthermore, the first magnetic member 130 is located on a side of the connecting arm 120 away from the second magnetic member 140. Thus, when the first magnetic member 130 attracts the first magnetic member 130, the connecting arm 120 supports the second magnetic member 140 to prevent the second magnetic member 140 from being attracted to the first magnetic member 130 and moving toward the first magnetic member 130.

[0051] like Figure 4 As shown, in some embodiments, a first mounting groove 113 is provided on the side wall of the sliding channel 111, and the first mounting groove 113 is located on the side of the limiting protrusion 112 close to the extreme position limiting portion 121, and the first magnetic member 130 is arranged in the first mounting groove 113, and the first magnetic member 130 is avoided and matched with the extreme position limiting portion 121.

[0052] It should be noted that by providing the first installation groove 113 on the side wall of the sliding channel 111, that is, providing the first installation groove 113 on the inner wall of the sliding arm 110, the first magnetic member 130 can be positioned and installed. In addition, the avoidance cooperation between the first magnetic member 130 and the extreme position limiter 121 means that when the sliding arm 110 slides relative to the connecting arm 120, the first magnetic member 130 will avoid the extreme position limiter 121 to prevent the first magnetic member 130 from hindering the movement of the sliding arm 110.

[0053] Specifically, the first magnetic member 130 is completely embedded in the first mounting groove 113 , that is, the first magnetic member 130 does not protrude from the inner surface of the sliding arm 110 , so that the first magnetic member 130 avoids the extreme position limiting portion 121 .

[0054] It is understandable that the first magnetic member 130 can be fixed in the first mounting groove 113 by using adhesive.

[0055] like Figure 4 As shown, in some embodiments, a second installation groove 122 is provided on the side of the connecting arm 120 facing away from the first magnetic component 130 , and the second magnetic component 140 is disposed in the second installation groove 122 . The second installation groove 122 can realize the positioning and installation of the second magnetic component 140 .

[0056] It is understandable that the second magnetic member 140 can be fixed in the second mounting groove 122 by using adhesive.

[0057] Furthermore, the second magnetic member 140 is disposed protruding from the second mounting groove 122. Thus, when the second magnetic member 140 needs to be disassembled, force can be applied to the side of the second magnetic member 140 to pull out the second magnetic member 140.

[0058] Combination Figure 3 and Figure 4In some embodiments, the sliding arm assembly 100 also includes a support arm 150, which extends into the sliding channel 111, and one end of the support arm 150 extends out of the sliding channel 111 and is used to connect with the headband assembly 200, and the support arm 150 and the connecting arm 120 are spaced apart along the thickness direction of the sliding arm 110.

[0059] It can be understood that one end of the support arm 150 is connected to the end of the headband assembly 200, and the other end of the support arm 150 extends into the sliding channel 111 of the sliding arm 110, wherein the sliding arm 110 can slide relative to the support arm 150, and the support arm 150 can provide auxiliary support to the sliding arm 110, and under the joint action of the connecting arm 120 and the support arm 150, the movement of the sliding arm 110 along the width direction of the sliding arm 110 can be limited, thereby improving the stability of the sliding arm 110.

[0060] Specifically, the support arm 150 and the connecting arm 120 are both fixedly connected to the headband assembly 200, and the support arm 150 and the connecting arm 120 are respectively abutted against the opposite side walls of the opening of the sliding channel 111 at one end close to the headband assembly 220. In this way, under the joint action of the connecting arm 120 and the support arm 150, the movement of the sliding arm 110 along the width direction of the sliding arm 110 can be limited, thereby improving the stability of the sliding arm 110.

[0061] Furthermore, a wiring channel 114 is formed between the connecting arm 120 and the supporting arm 150, and the wiring channel 114 is used for passing the wire 160. Moreover, the wire 160 is passed through the wiring channel 114, and the wire 160 can stretch freely in the wiring channel 114 during the sliding of the sliding arm 110, which can reduce the risk of the wire 160 being blocked from stretching and causing the wire to be stuck.

[0062] Further, the support arm 150 is located on a side of the connecting arm 120 away from the first magnetic member 130, that is, the wiring channel 114 formed between the connecting arm 120 and the support arm 150 is located on a side of the connecting arm 120 away from the first magnetic member 130. In other words, the wiring channel 114 is not provided between the first magnetic member 130 and the second magnetic member 140, so that the distance between the first magnetic member 130 and the second magnetic member 140 can be kept at a relatively close and appropriate distance, reducing the risk of a small attraction force between the first magnetic member 130 and the second magnetic member 140 due to the excessive distance between the two.

[0063] like Figures 1 to 4As shown, in the headset of the present invention, one end of the sliding arm assembly 100 is connected to the headband assembly 200, and the other end is connected to the sound unit 300. The distance between the sound unit 300 and the headband assembly 200 can be adjusted by sliding the sliding arm assembly 100 to adjust the wearing comfort of the user. Specifically, one end of the connecting arm 120 is connected to the end of the headband assembly 200, and the other end of the connecting arm 120 extends into the sliding channel 111 of the sliding arm 110. The sliding arm 110 is used to connect with the sound unit 300, wherein the sliding arm 110 can slide relative to the connecting arm 120, so that the sound unit 300 is close to or away from the headband assembly 200. When the slide arm 110 slides relative to the connecting arm 120 to approach the headband assembly 200 or move away from the headband assembly 200, the first magnetic member 130 and the second magnetic member 140 maintain mutual attraction, so that when the user slides the slide arm 110, the damping effect can be felt, and the slide arm 110 is stable and smooth during the sliding process, thereby improving the user experience. In addition, when the user stops sliding the slide arm 110, the first magnetic member 130 and the second magnetic member 140 can also be attracted to each other to achieve the positioning of the slide arm 110. Furthermore, through the cooperation between the extreme position limit portion 121 and the limit protrusion 112, the separation of the sliding arm 110 from the connecting arm 120 can be reduced. In addition, the extreme position limit portion 121 is located on the side of the connecting arm 120 that is away from the second magnetic component 140, and the limit protrusion 112 is located on the side of the connecting arm 120 that is away from the second magnetic component 140. When the sliding arm 110 slides relative to the connecting arm 120, the limit protrusion 112 will not contact the second magnetic component 140, and will not cause wear to the second magnetic component 140.
