When the first arc-shaped protrusion is rotatably connected to the first arc-shaped groove and the second arc-shaped protrusion is rotatably connected to the second arc-shaped groove, the first arc-shaped protrusion will be blocked by the above-mentioned step and cannot rotate to the position where the second arc-shaped groove is located. At the same time, since the radian of the first arc-shaped groove is greater than that of the second arc-shaped groove, and the radian of the first arc-shaped protrusion is less than or equal to that of the second arc-shaped protrusion, the angle corresponding to the first arc-shaped groove is greater than half of the whole circle, and the angle corresponding to the first arc-shaped protrusion is less than or equal to half of the whole circle. The angle difference between the two is the limiting angle at which the earclip can rotate relative to the earcup. In actual applications, the above-mentioned limiting angle can be set as needed. In this way, the rotation angle of the earcup relative to the earclip can be limited, avoiding damage to the headphone due to excessive rotation angle of the earcup. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in combination with the drawings, the preferred embodiments of the present utility model will be described in detail.
[0026] As Figures 1 to 4 shown, the embodiment of the present utility model provides an earphone cup rotation structure 100, including: an earphone cup 110, and an ear clip 120 rotatably connected to the earphone cup 110. A limiting hole 112 is provided on the earphone cup 110. The ear clip 120 includes a card convex 122 rotatably connected to the limiting hole 112. The limiting hole 112 includes a first arc groove 1122 and a second arc groove 1124 that are concentrically arranged. The radius of the first arc groove 1122 is greater than the radius of the second arc groove 1124, and the radian of the first arc groove 1122 is greater than the radian of the second arc groove 1124. The card convex 122 includes a first arc protrusion 1222 and a second arc protrusion 1224 that are concentrically arranged. The first arc protrusion 1222 is rotatably connected to the first arc groove 1122, and the second arc protrusion 1224 is rotatably connected to the second arc groove 1124. The radian of the first arc protrusion 1222 is less than or equal to the radian of the second arc protrusion 1224.
[0027] Specifically, through the earphone cup 110 and the ear clip 120 rotatably connected to the earphone cup 110, when using the earphone, the earphone cup 110 can rotate a certain angle relative to the ear clip 120, so as to better adapt to the needs of different people and improve the applicability during use. When the earphone cup 110 and the ear clip 120 are rotatably connected, by providing a limiting hole 112 on the earphone cup 110 and a card convex 122 rotatably connected to the limiting hole 112 on the ear clip 120, the rotational connection between the two is ensured.
[0028] In addition, the earcups 110 need to be electrically connected through a wire. The wire usually passes through the inside of the earclip 120 and extends into the earcup 110. In order to prevent the unrestricted rotation between the clamping protrusion 122 and the limiting hole 112 from affecting the normal connection of the wire, a corresponding limiting structure needs to be set at the rotating connection. On the premise of having a certain rotation angle for angle adjustment, it can also play a role in protecting the wire. In practical applications, the limiting hole 112 can be set as concentric first arc-shaped grooves 1122 and second arc-shaped grooves 1124, and the radius of the first arc-shaped groove 1122 is set to be greater than the radius of the second arc-shaped groove 1124. In this way, when the clamping protrusion 122 is provided with concentric first arc-shaped protrusions 1222 and second arc-shaped protrusions 1224, the first arc-shaped protrusion 1222 cooperates with the first arc-shaped groove 1122, and the second arc-shaped protrusion 1224 cooperates with the second arc-shaped groove 1124. When the first arc-shaped protrusion 1222 can be rotatably connected to the first arc-shaped groove 1122 and the second arc-shaped protrusion 1224 can be rotatably connected to the second arc-shaped groove 1124, the radius of the first arc-shaped protrusion 1222 is greater than the radius of the second arc-shaped protrusion 1224. At the same time, the total radian formed by the enclosure of the first arc-shaped groove 1122 and the second arc-shaped groove 1124 is 2π. By setting the radian of the first arc-shaped groove 1122 to be greater than the radian of the second arc-shaped groove 1124 and setting the radian of the first arc-shaped protrusion 1222 to be less than or equal to the radian of the second arc-shaped protrusion 1224, when the clamping protrusion 122 rotates with the limiting hole 112, both sides of the rotation direction of the first arc-shaped protrusion 1222 can abut against the junction of the first arc-shaped groove 1122 and the second arc-shaped groove 1124 during rotation, thereby playing a role in limiting the rotation of the earclip 120.
[0029] The earcup rotation structure 100 provided by the embodiment of the present application enables the rotation connection between the earcup 110 and the earclip 120 through the cooperation of a limiting hole 112 provided on the earcup 110 and a clamping protrusion 122 provided on the earclip 120 and rotatably connected to the limiting hole 112. The limiting hole 112 is formed by enclosing a first arc-shaped groove 1122 and a second arc-shaped groove 1124 that are concentrically arranged. Since the radius of the first arc-shaped groove 1122 is greater than the radius of the second arc-shaped groove 1124, a step is formed at the junction of the first arc-shaped groove 1122 and the second arc-shaped groove 1124. When the first arc-shaped protrusion 1222 is rotatably connected to the first arc-shaped groove 1122 and the second arc-shaped protrusion 1224 is rotatably connected to the second arc-shaped groove 1124, the first arc-shaped protrusion 1222 will be blocked by the above-mentioned step and cannot rotate to the position where the second arc-shaped groove 1124 is located. At the same time, since the radian of the first arc-shaped groove 1122 is greater than the radian of the second arc-shaped groove 1124, and the radian of the first arc-shaped protrusion 1222 is less than or equal to the radian of the second arc-shaped protrusion 1224, the angle corresponding to the first arc-shaped groove 1122 is greater than half of the whole circle, and the angle corresponding to the first arc-shaped protrusion 1222 is less than or equal to half of the whole circle. The angle difference between the two is the limiting angle at which the earclip 120 can rotate relative to the earcup 110. In actual applications, the above-mentioned limiting angle can be set as needed. In this way, the rotation angle of the earcup 110 relative to the earclip 120 can be limited, avoiding damage to the earphone caused by excessive rotation angle of the earcup 110.
[0030] As Figures 2 to 5 shown, the earcup 110 includes a first cup body 114 and a second cup body 116 that are buckled with each other. The limiting hole 112 is located on the first cup body 114. A first limiting groove 1222a is provided on the first arc-shaped protrusion 1222, a clamping plate 1162 corresponding to the first arc-shaped protrusion 1222 is provided on the second cup body 116, and a second limiting groove 1162a is provided on the clamping plate 1162. The first limiting groove 1222a and the second limiting groove 1162a are engaged to limit the axial direction of the clamping protrusion 122.
[0031] Specifically, by providing a first limiting groove 1222a on the first arc-shaped protrusion 1222 and a clamping plate 1162 corresponding to the first arc-shaped protrusion 1222 on the second cup body 116, when the second cup body 116 is buckled with the first cup body 114 after the clamping protrusion 122 is inserted into the limiting hole 112, the clamping plate 1162 can be matched with the first limiting groove 1222a to limit the axial direction of the clamping protrusion 122 and prevent the clamping protrusion 122 from accidentally disengaging from the limiting hole 112. It can be understood that the radius of the first arc-shaped protrusion 1222 is larger than that of the second arc-shaped protrusion 1224, which is convenient for cooperation with the clamping plate 1162. Both the first limiting groove 1222a and the second limiting groove 1162a are arc-shaped, which will not affect the rotation of the clamping protrusion 122 while limiting the axial direction of the clamping protrusion 122.
[0032] As Figure 4 shown, the ear clip 120 includes a housing 124 and a cover 126 fastened to the housing 124. The housing 124 is semi-circular, and the clamping protrusions 122 are respectively located at opposite ends of the housing 124. At least one of the clamping protrusions 122 is provided with a wire groove 1222b, and the wire groove 1222b communicates with the housing 124. A pressing strip 1262 corresponding to the wire groove 1222b is provided on the cover 126, and the pressing strip 1262 is located at the notch of the wire groove 1222b.
[0033] Specifically, by setting the housing 124 to be semi-circular, it is convenient to respectively arrange the clamping protrusions 122 at both ends of the housing 124 for cooperation with the ear cup 110, which is beneficial to ensuring the stability of the cooperation. In order to ensure that the wire can be electrically connected to the sound generating unit in the ear cup 110, a wire groove 1222b needs to be provided on at least one of the clamping protrusions 122, and the wire groove 1222b communicates with the housing 124 to facilitate wire routing. In addition, by providing a pressing strip 1262 corresponding to the wire groove 1222b on the cover 126, after the wire routing is completed, the wire can be limited by the pressing strip 1262 to prevent accidental exposure from the wire groove 1222b, and the wire can be protected.
[0034] As Figure 6 shown, a protective cover 1142 is further provided on the inner circle of the first cover 114. A protective cavity 1142a is formed between the protective cover 1142 and the first cover 114, and the clamping protrusion 122 extends into the protective cavity 1142a.
[0035] Specifically, by providing the protective cover 1142 on the inner circle of the first cover 114, after the clamping protrusion 122 extends into the first cover 114 from the limiting hole 112, the clamping protrusion 122 can be isolated from other components in the first cover 114 by the protective cover 1142, so that the clamping protrusion 122 rotates in the protective cavity 1142a, avoiding the clamping protrusion 122 affecting other structures in the ear cup 110, which is beneficial to ensuring the stability and reliability during use.
[0036] Please continue to refer to Figure 6 , a through hole 1144 is provided on the protective cover 1142 for the wire to pass through. In this way, the wire passing through the ear clip 120 can extend more naturally from the protective cavity 1142a, avoiding the formation of a certain bend angle between the extending wire and the wire groove 1222b, and avoiding affecting the service life of the wire due to easy wear of the wire.
[0037] As Figure 4 shown, a first card slot 1242 is provided on the housing 124, and a first buckle 1264 corresponding to the first card slot 1242 is provided on the cover 126. The first buckle 1264 is fastened in the first card slot 1242.
[0038] Specifically, when the housing 124 is mated with the cover 126, they can be connected by the cooperation of the first buckle 1264 and the first card slot 1242, which is beneficial to simplify the connection form and improve the convenience during connection. To ensure a more reliable connection between the two, screws can be added for connection on this basis.
[0039] As Figure 4 shown, a connecting portion 1244 for connecting with the headband bracket is further provided on the housing 124, and the connecting portion 1244 is located on one side of the housing 124 close to one of its ends.
[0040] Adopting the above method, it is convenient for the ear clip 120 to be connected with the headband bracket through the connecting portion 1244. At the same time, the connecting portion 1244 is located on one side of the housing 124 close to one of its ends, which can better conform to the ergonomic design and make the wearing experience more comfortable.
[0041] As Figure 2 shown, an annular protrusion 1146 is provided on the edge of the first cover 114, and the ear clip 120 can abut against the annular protrusion 1146.
[0042] Specifically, the annular protrusion 1146 provided on the edge of the first cover 114 can play a role in limiting the ear clip 120, avoiding the rotational stress from concentrating on the limiting hole 112, which is beneficial to making the force-bearing position of the ear cup 110 more dispersed and preventing damage due to overly concentrated force, thus ensuring the reliability of the connection.
[0043] As Figure 2 shown, a retaining ring 130 is further provided on the first cover 114. A second card slot 1148 is provided on the first cover 114, and a second buckle 132 corresponding to the second card slot 1148 is provided on the retaining ring 130. The second buckle 132 is snapped into the second card slot 1148, and the outer ring of the retaining ring 130 can be aligned with the annular protrusion 1146.
[0044] Specifically, the retaining ring 130 can prevent the ear clip 120 from protruding outward relative to the first cover 114. With the cooperation of the ear clip 120 and the retaining ring 130, the outer ring of the ear cup 110 can be made smoother and more natural, which is beneficial to improving the comfort during use. When the first cover 114 is mated with the retaining ring 130, they can be connected by the cooperation of the second buckle and the second card slot 1148, which is beneficial to simplify the connection form and improve the convenience during connection.
[0045] The present utility model also discloses a head-mounted earphone, which includes a head-mounted bracket and the earcup rotation structure 100 in the foregoing embodiment, and the head-mounted bracket is connected to the ear clip 120 of the earcup rotation structure 100. This head-mounted earphone has the same structure and beneficial effects as the earcup rotation structure 100 in the foregoing embodiment. The structure and beneficial effects of the earcup rotation structure 100 have been described in detail in the foregoing embodiment and will not be elaborated herein.
[0046] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit the same. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present utility model.
