[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , which are a stereoscopic view, an exploded view and a cross-sectional view of the earmuff structure of the first embodiment of the present invention; as shown in the figure, the earmuff structure 1 of this embodiment includes a fixed cover 10 and a speaker structure, and the speaker structure has a rear cover 11, and the rear cover 11 is movably arranged on the inner surface of the fixed cover 10. A positioning member 101 is provided on the inner surface of the fixed cover 10, and a spherical convex portion 1011 is provided at one end of the positioning member 101 away from the inner surface of the fixed cover 10, and a spherical groove 111 is provided on the surface of the rear cover 11 facing the fixed cover 10. When the rear cover 11 is arranged on the fixed cover 10, the spherical convex portion 1011 of the positioning member 101 is clamped in the spherical groove 111, and the rear cover 11 can be tilted relative to the central axis of the positioning member 101. In other words, the spherical convex portion 1011 is the central fulcrum of the rear cover 11, and the periphery of the rear cover 11 can be tilted toward the fixed cover 10 with the spherical convex portion 1011 as the fulcrum. The center point of the fixed cover 10 is located on the center axis of the positioning member 101 , and the center point of the rear cover 11 is located on the center axis of the spherical groove 111 . When the spherical protrusion 1011 of the positioning member 101 is arranged in the spherical groove 111 , the center point of the rear cover 11 corresponds to the center point of the fixed cover 10 .

[0017] When the earmuff structure 1 of this embodiment is in use, the earmuff structure 1 covers the user's ears, and the user's ears can drive the rear cover 11 of the speaker structure to tilt relative to the central axis of the positioning member 101, so that the earmuff structure 1 can automatically adjust according to the user's ear shape, so that the earmuff structure 1 fits the user's ears.

[0018] The earmuff structure 1 of this embodiment further includes a fixing member 12, which passes through the back cover 11 from the inner surface of the back cover 11 and is fixed to the spherical protrusion 1011. The fixing member 12 is not connected to the back cover 11 and does not restrict the movement of the back cover 11, so as to prevent the back cover 11 from being separated from the fixed cover 10. In this embodiment, a through hole 112 is provided at the center of the back cover 11, and the through hole 112 is connected to the spherical groove 111. The central axis of the through hole 112 is on the same line as the central axis of the spherical groove 111. The fixing member 12 passes through the through hole 112 to be connected to the spherical protrusion 1011 located in the spherical groove 111. The outer diameter of one end of the fixing member 12 passing through the through hole 112 is smaller than the inner diameter of the through hole 112, and the outer diameter of one end of the fixing member 12 located in the back cover 11 is larger than the inner diameter of the through hole 112, and blocks the back cover 11 to prevent the back cover 11 from being separated from the fixed cover 10. The fixing member 12 of this embodiment includes a screw 121 and a gasket 122. The screw 121 is inserted into the gasket 122. When the fixing member 12 is disposed on the spherical protrusion 1011, one end of the screw 121 passes through the through hole 112 and is locked in the spherical protrusion 1011. The gasket 122 is located on the inner surface of the rear cover 11, that is, the outer diameter of the gasket 122 is larger than the inner diameter of the through hole 112, so as to prevent the rear cover 11 from being separated. There is a gap between the gasket 122 and the inner surface of the rear cover 11, that is, there is a gap between the end of the fixing member 12 located in the rear cover 11 and the inner surface of the rear cover 11, so as to prevent the fixing member 12 from affecting the movement of the rear cover 11.

[0019] The inner surface of the fixed cover 10 is also provided with a stopper 102, one end of which is located around the positioning member 101, and the other end thereof extends in a direction away from the positioning member 101, and the extension direction of the stopper 102 is perpendicular to the central axis of the positioning member 101. The rear cover 11 has a stopper groove 113 on the surface facing the fixed cover 10, and the stopper groove 113 is provided corresponding to the stopper 102, so that one end of the stopper groove 113 is connected to the spherical groove 111, and the other end thereof extends in a direction away from the spherical groove 111, and the stopper groove 113 is connected to the spherical groove 111, and the extension direction of the stopper groove 113 is perpendicular to the central axis of the spherical groove 111. When the rear cover 11 is disposed on the fixed cover 10 , the spherical protrusion 1011 of the positioning member 101 is disposed in the spherical groove 111 , and the limiting member 102 is disposed in the limiting groove 113 . The limiting member 102 limits the rear cover 11 to rotate around the central axis of the positioning member 101 of the fixed cover 10 .

[0020] The vertical height of the top surface of the stopper 102 of this embodiment relative to the inner surface of the fixed cover 10 is smaller than the vertical height of the vertex of the spherical protrusion 1011 relative to the inner surface of the fixed cover 10, and there is a gap between the top surface of the stopper 102 and the bottom surface of the stopper groove 113, which can still allow the rear cover 11 to tilt relative to the fixed cover 10, and limit the tilting amplitude of the rear cover 11 relative to the central axis of the positioning member 101 in the extension direction of the stopper 102. The top surface of the stopper 102 of this embodiment can tilt in the direction close to the positioning member 101, that is, the top surface of the stopper 102 tilts relative to the positioning member 101, and there is an angle between the extension direction of the top surface of the stopper 102 and the central axis of the positioning member 101, and the angle is less than 90 degrees. The tilting amplitude of the top surface of the stopper 102 is adjusted by controlling the size of the angle, and the tilting amplitude of the rear cover 11 relative to the positioning member 101 in the extension direction of the stopper 102 is controlled according to the tilting amplitude of the top surface of the stopper 102. In this embodiment, the limiting member 102 is connected to the positioning member 101 , and there are two limiting members 102 , which are arranged opposite to each other.

[0021] Preferably, a buffer pad 103 is further provided on the inner surface of the fixed cover 10. The buffer pad 103 is arranged along the periphery of the positioning member 101, and the outer surface of the rear cover 11 contacts the buffer pad 103. The buffer pad 103 reduces the contact between the rear cover 11 and the fixed cover 10. When the rear cover 11 is tilted relative to the positioning member 101 by an external force, the rear cover 11 compresses the buffer pad 103. The buffer pad 103 generates elastic force due to compression. The buffer pad 103 supports the rear cover 11 through the elastic force, so that the earmuff structure 1 can better fit the user's ears. When the earmuff structure 1 is not in use, the elastic force generated by the compressed buffer pad 103 can help the rear cover 11 return to its original position.

[0022] See also Figure 5 , which is a three-dimensional diagram of the earmuff structure of the second embodiment of the present invention; as shown in the figure, the earmuff structure 1 of this embodiment is different from the earmuff structure of the above embodiment in that the earmuff structure 1 of this embodiment further includes a protective cover 13, which is arranged on the outer surface of the fixed cover 10. The protective cover 13 is used to protect the fixed cover 10 and the speaker structure to prevent external foreign matter from entering the fixed cover 10 and the speaker structure. In addition, the appearance of the protective cover 13 can be changed to improve the aesthetics of the earmuff structure 1.

[0023] See also Figure 6, which is a stereoscopic diagram of a headset according to the third embodiment of the present invention; as shown in the figure, the headset 2 of this embodiment includes a headset support 21 and two earmuff structures 22, the two earmuff structures 22 are respectively arranged at the two ends of the headset support 21, the earmuff structure 22 uses the earmuff structure disclosed in the above embodiment, and the earmuff structure 22 of this embodiment uses the earmuff structure of the second embodiment. When a user uses the headset 2 of this embodiment, the earmuff structure 22 can be adjusted according to the ear shape of the user, that is, the rear cover of the speaker structure can be tilted relative to the positioning member according to the ear shape of the user, so that the earmuff structure 22 conforms to the ear shape of the user.

[0024] In summary, the present invention provides an earmuff structure and a headphone. The earmuff structure of the present invention mainly combines the spherical protrusion of the fixed cover with the spherical groove of the back cover so that the back cover can be tilted relative to the positioning piece of the fixed cover. When the user uses the headphone, the earmuff structure covers the user's ears, and the back cover of the earmuff structure is tilted relative to the positioning piece of the fixed cover according to the ear shape of the user, so that the earmuff structure fits the user's ears. The limiting piece of the fixed cover is combined with the limiting groove of the back cover to prevent the fixed cover from rotating. The buffer pad of the fixed cover is in contact with the outer surface of the back cover. When the back cover is tilted relative to the positioning piece, the buffer pad can elastically support the back cover, so that the earmuff structure can better fit the user's ears.
