[0036] The first buckle 11 and the second buckle 21 in the embodiment are at least one of which is made of a material capable of elastic deformation, to ensure that the first buckle 11 and the second buckle 21 can be smoothly clamped and matched, and the material can be plastic, rubber or silicone.

[0037] Before continuing to introduce the ear cover structure 100 of the embodiment, the axial direction and the radial direction of the ear cover structure 100 are defined first, to facilitate the subsequent description. The axial direction of the ear cover structure 100 referred to by the utility model is the thickness direction of the ear cover structure 100, that is, the axial direction of the ear cover structure 100 is the direction of the ear cover structure 100 close to and away from the ear after the ear cover structure 100 is worn on the ear, and the axis of the ear cover structure 100 is a straight line penetrating the geometric center of the ear cover structure 100 along the axial direction of the ear cover structure 100, and the radial direction of the ear cover structure 100 is the direction perpendicular to the axial direction of the ear cover structure 100, that is, the direction perpendicular to the thickness direction of the ear cover structure 100. The ear cover structure 100 comprises the ear cover body 1 and the ear pad 2, the axial direction and the radial direction of the ear cover body 1 and the axial direction and the radial direction of the ear pad 2 are consistent with the axial direction and the radial direction of the ear cover structure 100, and the definition of the axis is also consistent.

[0038] The ear cover structure 100 comprises the ear cover body 1 and the ear pad 2. Figure 2 As a reference, when the ear pad 2 is mounted on the ear cover body 1, the dot-dash line in the figure is the axis of the ear cover body 1 and the ear pad 2, and the axes of the two coincide at this time.

[0039] As shown in the figure, the ear cover structure 100 according to one embodiment of the utility model comprises an ear cover body 1 and an ear pad 2. Figures 1-5

[0040] ​The ear cover body 1 is provided with a first buckle 11, and the first buckle 11 has a first guide inclined surface 111 and a first limiting surface 112; the ear pad 2 is provided with a second buckle 21, and the second buckle 21 has a second guide inclined surface 211 and a second limiting surface 212; wherein the first buckle 11 and the second buckle 21 are guided and buckled through the first guide inclined surface 111 and the second guide inclined surface 211 and are limited and fixed through the first limiting surface 112 and the second limiting surface 212.

[0041] Specifically, the ear pad 2 is configured in a ring shape to adapt to the shape of the user's ear, and is usually made of leather, fabric or the like to make the surface soft, so as to reduce the friction between the earphone 200 and the ear, improve the wearing comfort of the earphone 200, and thus improve the user's satisfaction. The ear cover body 1 is used to protect the driving unit inside the earphone 200 from physical damage from the outside, and reduce the possibility of damage to the earphone 200. The ear cover body 1 can also be used to fix the ear pad 2 to improve the reliability of the ear pad 2. When the ear cover body 1 is used to fix the ear pad 2, the ear cover body 1 and the ear pad 2 are connected, and the connection can be achieved by buckling. The connection method is simple and reliable, easy to realize the connection or separation between the ear cover body 1 and the ear pad 2, and convenient for the user to replace the ear pad 2 according to his own preference, or replace the ear pad 2 when it is aging and invalid, thereby prolonging the service life of the earphone 200.

[0042] The ear cover body 1 is provided with a first buckle 11, and the ear pad 2 is provided with a second buckle 21. The first buckle 11 can be connected with the second buckle 21, that is, the connection between the ear cover body 1 and the ear pad 2 can be achieved by the connection between the first buckle 11 and the second buckle 21, and the ear pad 2 can be fixed, ensuring reliable work of the ear pad 2, and the ear cover structure 100 can be an integral whole, improving the structural strength of the ear cover body 1. When the ear cover body 1 and the ear pad 2 are connected, the first buckle 11 can move towards the second buckle 21, or the second buckle 21 can move towards the first buckle 11, or the first buckle 11 and the second buckle 21 can move towards each other, so as to facilitate the connection of the first buckle 11 and the second buckle 21, and realize the connection between the ear cover body 1 and the ear pad 2.

[0043] Moreover, the first buckle 11 has a first guide slope 111, and the second buckle 21 has a second guide slope 211, the first guide slope 111 and the second guide slope 211 can play a guiding role, and the first guide slope 111 and the second guide slope 211 can be slidably matched, that is, when the first buckle 11 and the second buckle 21 are connected through clamping, the first buckle 11 and the second buckle 21 can be guided by the first guide slope 111 and the second guide slope 211, so that the first buckle 11 and the second buckle 21 can slide along the first guide slope 111 and the second guide slope 211 until clamping is achieved, that is, the first buckle 11 and the second buckle 21 can be clamped into the first guide slope 111 and the second guide slope 211, thereby improving the accuracy of the movement direction of the first buckle 11 and the second buckle 21, ensuring that the first buckle 11 and the second buckle 21 can be clamped and matched, and the first guide slope 111 and the second guide slope 211 can also buffer the interaction force when the first buckle 11 and the second buckle 21 are clamped and matched, thereby reducing the possibility of deformation failure of the first buckle 11 and the second buckle 21, and prolonging the service life of the first buckle 11 and the second buckle 21.

[0044] Meanwhile, the first buckle 11 has a first limiting surface 112, and the second buckle 21 has a second limiting surface 212, the first limiting surface 112 and the second limiting surface 212 can play a limiting role, that is, after the first buckle 11 and the second buckle 21 are connected through clamping, the movement of the second buckle 21 and the first buckle 11 can be limited by the first limiting surface 112 and the second limiting surface 212 respectively, so as to avoid the movement of the first buckle 11 and the second buckle 21 away from each other, causing the separation of the first buckle 11 and the second buckle 21, and further causing the separation of the ear cover body 1 and the ear pad 2, that is, the first buckle 11 and the second buckle 21 can be fixed by the first limiting surface 112 and the second limiting surface 212, so as to improve the connection reliability between the ear cover body 1 and the ear pad 2, and further improve the reliability of fixing the ear pad 2, and ensure the reliable work of the ear pad 2.

[0045] According to the ear cover structure 100, the first buckle 11 and the second buckle 21 are arranged to connect the ear cover body 1 and the ear pad 2, the first guide slope 111 and the second guide slope 211 are arranged to improve the accuracy of the movement direction of the first buckle 11 and the second buckle 21, ensure that the first buckle 11 and the second buckle 21 can be clamped and matched, and buffer the interaction force when the first buckle 11 and the second buckle 21 are clamped and matched, thereby reducing the possibility of deformation failure of the first buckle 11 and the second buckle 21, prolonging the service life of the first buckle 11 and the second buckle 21, and the first limiting surface 112 and the second limiting surface 212 are arranged to improve the connection reliability between the ear cover body 1 and the ear pad 2, thereby improving the reliability of fixing the ear pad 2, and ensuring the reliable work of the ear pad 2.

[0046] In some embodiments, the first buckle 11 is configured to protrude along the radial direction of the ear cover body 1 towards the ear pad 2, and the second buckle 21 is configured to protrude along the radial direction of the ear pad 2 towards the ear cover body 1, and the first buckle 11 and the second buckle 21 are clamped along the axial direction of the ear cover structure 100.

[0047] Specifically, as shown in Figures 2-3 , the first buckle 11 can be clamped with the second buckle 21 to realize the connection between the ear cover body 1 and the ear pad 2. The first buckle 11 is configured to protrude along the radial direction of the ear cover body 1 towards the ear pad 2, and the second buckle 21 is configured to protrude along the radial direction of the ear pad 2 towards the ear cover body 1. That is, the first buckle 11 can be configured to extend towards the direction close to the second buckle 21, and the second buckle 21 can be configured to extend towards the direction close to the first buckle 11. Thus, the first buckle 11 and the second buckle 21 can be close to each other along the radial direction and be clamped along the axial direction. That is, the first buckle 11 and the second buckle 21 are clamped along the axial direction of the ear cover body 1 and the axial direction of the ear pad 2, which coincide with the axial direction of the ear cover structure 100. Thus, the first buckle 11 and the second buckle 21 can be clamped along the axial direction of the ear cover structure 100 to realize the connection between the ear cover body 1 and the ear pad 2.

[0048] It should be noted that, Figure 3 is a partial cross-sectional view of the ear cover structure 100. In order to clearly show the structural details in the figure, the cross-sectional lines in Figure 3 are hidden.

[0049] In some embodiments, the first buckle 11 has a first protruding portion 113 protruding along the radial direction of the ear cover body 1 on the side close to the second buckle 21, and the first guide slope 111 and the first limiting surface 112 are respectively formed on the two sides of the first protruding portion 113. The second buckle 21 has a second protruding portion 213 protruding along the radial direction of the ear pad 2 on the side close to the first buckle 11, and the second guide slope 211 and the second limiting surface 212 are respectively formed on the two sides of the second protruding portion 213.

[0050] Specifically, as shown in Figure 3As shown, the first buckle 11 has a first protruding portion 113, the second buckle 21 has a second protruding portion 213, and the first protruding portion 113 and the second protruding portion 213 can be clamped and matched, that is, the clamped and matched first buckle 11 and the second buckle 21 can be realized through the clamped and matched first protruding portion 113 and the second protruding portion 213, and the connection between the earmuff body 1 and the ear pad 2 can be realized, and the first protruding portion 113 is formed on the side of the first buckle 11 close to the second buckle 21, and the second protruding portion 213 is formed on the side of the second buckle 21 close to the first buckle 11, that is, the first protruding portion 113 and the second protruding portion 213 can extend towards each other, and the first protruding portion 113 and the second protruding portion 213 can be close to each other and clamped and matched.

[0051] In the embodiment, the ear pad 2 can be connected to the outer side of the earmuff body 1, and the outer side of the earmuff body 1 can be covered, and the connection between the earmuff body 1 and the ear pad 2 can be sealed, the outer side is a side away from the center of the earmuff body 1 in the radial direction, and the inner side is a side towards the center of the earmuff body 1 in the radial direction.

[0052] In addition, the first protruding portion 113 protrudes in the radial direction of the earmuff body 1, and the second protruding portion 213 protrudes in the radial direction of the ear pad 2, that is, the first protruding portion 113 and the second protruding portion 213 can extend towards each other, so as to facilitate the clamped and matched first protruding portion 113 and the second protruding portion 213, and the first protruding portion 113 and the second protruding portion 213 can have a certain length, so as to improve the connection reliability between the first protruding portion 113 and the second protruding portion 213.

[0053] In addition, the first guiding slope 111 and the first limiting face 112 are respectively formed on the two sides of the first protruding portion 113, that is, the first guiding slope 111 and the first limiting face 112 are distributed in a spaced manner, so as to avoid interference between the first guiding slope 111 and the first limiting face 112, and the movement of the first buckle 11 cannot be guided or the movement of the second buckle 21 cannot be limited, that is, the working reliability of the first guiding slope 111 and the first limiting face 112 can be improved, and the second guiding slope 211 and the second limiting face 212 are respectively formed on the two sides of the second protruding portion 213, that is, the second guiding slope 211 and the second limiting face 212 are distributed in a spaced manner, so as to avoid interference between the second guiding slope 211 and the second limiting face 212, and the movement of the second buckle 21 cannot be guided or the movement of the first buckle 11 cannot be limited, that is, the working reliability of the second guiding slope 211 and the second limiting face 212 can be improved.

[0054] In some embodiments, the first guiding slope 111 is inclined relative to the axial direction of the earmuff body 1 at a first inclination angle, and the first inclination angle is A1, and satisfies: 10°≤A1≤80°.

[0055] Specifically, as shown in FIG. 1, Figure 4As shown, the first guide slope 111 is configured to be inclined relative to the axial direction of the ear cover body 1 to guide the movement of the first buckle 11, ensure the accuracy of the movement direction of the first buckle 11, and buffer the interaction force when the first buckle 11 and the second buckle 21 are engaged, so as to reduce the possibility of deformation failure of the first buckle 11 and the second buckle 21. The angle of the first guide slope 111 relative to the axial direction of the ear cover body 1 can be a first inclination angle A1. A1 cannot be too large or too small. If it is too large, the buffering effect on the interaction force will be weakened. If it is too small, the guiding effect on the first buckle 11 will be lost. A1 can be between 10° and 80°, i.e. A1 can be 10°, 30° or 70°, etc. All of them can ensure the guiding effect of the first guide slope 111 on the first buckle 11, and at the same time, the first guide slope 111 can also buffer the interaction force when the first buckle 11 and the second buckle 21 are engaged, which is beneficial to improve user satisfaction.

[0056] The angle of the second guide slope 211 relative to the axial direction of the ear pad 2 is a second inclination angle, and the second inclination angle is A2, and satisfies: 10°≤A2≤80°.

[0057] Specifically, the second guide slope 211 is configured to be inclined relative to the axial direction of the ear pad 2 to guide the movement of the second buckle 21, ensure the accuracy of the movement direction of the second buckle 21, and buffer the interaction force when the first buckle 11 and the second buckle 21 are engaged, so as to reduce the possibility of deformation failure of the first buckle 11 and the second buckle 21. The angle of the second guide slope 211 relative to the axial direction of the ear pad 2 can be a second inclination angle A2. A2 cannot be too large or too small. If it is too large, the buffering effect on the interaction force will be weakened. If it is too small, the guiding effect on the second buckle 21 will be lost. A2 can be between 10° and 80°, i.e. A2 can be 10°, 30° or 70°, etc. All of them can ensure the guiding effect of the second guide slope 211 on the second buckle 21, and at the same time, the first guide slope 111 can also buffer the interaction force when the first buckle 11 and the second buckle 21 are engaged, which is beneficial to improve user satisfaction.

[0058] In some embodiments, the first inclination angle A1=A2.

[0059] Specifically, the first inclination angle A1 is an angle of the axial inclination of the first guide slope 111 relative to the ear cover body 1, the second inclination angle A2 is an angle of the axial inclination of the second guide slope 211 relative to the ear pad 2, and the first guide slope 111 and the second guide slope 211 are used to guide the first buckle 11 and the second buckle 21 when the first buckle 11 and the second buckle 21 are clamped and matched to ensure the accuracy of the movement direction of the first buckle 11 and the second buckle 21. A1 and A2 can be equal, that is, the inclination angles of the first guide slope 111 and the second guide slope 211 can be equal, so that the first guide slope 111 can be attached to the second guide slope 211, so as to better guide the first buckle 11 and the second buckle 21, and can reduce the friction between the first buckle 11 and the second buckle 21, thereby reducing the wear of the first buckle 11 and the second buckle 21, and prolonging the service life of the first buckle 11 and the second buckle 21.

[0060] In some embodiments, the angle of the axial inclination of the first limiting surface 112 relative to the ear cover body 1 is a third inclination angle, and the third inclination angle is A3, and satisfies: 70°≤A3≤90°.

[0061] Specifically, as shown in Figure 4 the first limiting surface 112 is configured to be inclined relative to the axial direction of the ear cover body 1 to limit the movement of the second buckle 21 by the first limiting surface 112, avoid the movement of the second buckle 21 away from the first buckle 11, and thereby avoid the separation of the first buckle 11 and the second buckle 21, and improve the connection reliability between the first buckle 11 and the second buckle 21. The angle of the axial inclination of the first limiting surface 112 relative to the ear cover body 1 can be a third inclination angle A3, which cannot be too small, otherwise the effect of limiting the movement of the second buckle 21 will be invalid. A3 can be between 70° and 90°, that is, A3 can be 70°, 80° or 90°, etc., which can ensure the reliable limitation of the movement of the second buckle 21 by the first limiting surface 112, and is beneficial to improve the connection reliability between the first buckle 11 and the second buckle 21.

[0062] The angle of the axial inclination of the second limiting surface 212 relative to the ear pad 2 is a fourth inclination angle, and the fourth inclination angle is A4, and satisfies: 70°≤A4≤90°.

[0063] Specifically, the second limiting surface 212 is configured to be inclined relative to the axial direction of the ear pad 2 to limit the movement of the first buckle 11 away from the second buckle 21, thereby avoiding the separation of the first buckle 11 and the second buckle 21, and improving the connection reliability between the first buckle 11 and the second buckle 21. The second limiting surface 212 can be inclined at a fourth inclination angle A4 relative to the axial direction of the ear pad 2. A4 cannot be too small, otherwise the limiting effect on the movement of the first buckle 11 will be lost. A4 can be between 70° and 90°, i.e. A4 can be 70°, 80° or 90°, etc., all of which can ensure reliable limitation of the movement of the first buckle 11 by the second limiting surface 212, thereby improving the connection reliability between the first buckle 11 and the second buckle 21.

[0064] In some embodiments, the third inclination angle A3 and the fourth inclination angle A4 are both equal to 90°.

[0065] Specifically, the third inclination angle A3 is the angle at which the first limiting surface 112 is inclined relative to the axial direction of the ear cover body 1, and the fourth inclination angle A4 is the angle at which the second limiting surface 212 is inclined relative to the axial direction of the ear pad 2.
