[0031] The following further describes the embodiments of the present application in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0032] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "front", "rear", "top", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the embodiments of the present application 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 embodiments of the present application. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0033] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "connected" and "coupled" 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0034] In the related art, it is usually difficult for a head-mounted earphone to be adjusted and matched according to wearers with different head circumferences and ear shapes, and the versatility is poor, resulting in gaps easily generated between the earcup assembly and the ears, reducing the noise reduction effect of the head-mounted earphone and making it difficult to provide a stable and comfortable wearing experience.

[0035] Based on the above situation, an embodiment of the present application provides a head-mounted earphone 10. Please refer to Figures 1 to 6 . The head-mounted earphone 10 includes a headband 11 and earcup assemblies 12 connected to both ends of the headband 11. The earcup assembly 12 includes an ear shell 121, a bracket 122, and a connecting member 123. An accommodation cavity 121a and an opening 121b are provided inside the ear shell 121. The opening 121b communicates with the accommodation cavity 121a. The bracket 122 is disposed in the accommodation cavity 121a. The bracket 122 includes a connecting portion 122a and rotating portions 122b provided at both ends of the connecting portion 122a. One ends of the two rotating portions 122b are respectively connected to the connecting portion 122a, and the other ends extend at least along a first direction and are rotatably connected to both sides of the ear shell 121 along a second direction. One end of the connecting member 123 is connected to the headband 11, and the other end is connected to the connecting portion 122a. Among them, the ear shell 121 can rotate relative to the bracket 122 about a first axis. The first axis is parallel to the second direction. The direction of the line connecting both ends of the headband 11 is the third direction. The first direction, the second direction, and the third direction intersect each other.

[0036] It should be noted that the cross-section of the ear shell 121 can be in the shape of a long strip, a square, a circle, etc., and there is no limitation here.

[0037] Exemplarily, the first direction is the length direction of the ear shell 121, the second direction is the width direction of the ear shell 121, and the first direction is perpendicular to the second direction.

[0038] Exemplarily, the head-mounted part 11 has a strip-shaped bent structure. The head-mounted part 11 cooperates with the wearer's head, and the earcup assembly 12 cooperates with the wearer's ear to realize the wearing of the headphone 10.

[0039] Exemplarily, the head-mounted part 11 can slide and expand or contract to increase or decrease the distance between the two earcup assemblies 12, increasing the adaptability of the headphone 10 and improving the comfort of the wearer.

[0040] The earcup assembly 12 includes an ear shell 121, a bracket 122 and a connecting member 123. The ear shell 121 is used to accommodate the components of the earcup assembly 12, such as a sound generating unit and a microphone.

[0041] It should be noted that the material of the connecting member 123 can be a light metal alloy, such as zinc alloy, so as to reduce the overall weight of the headphone 10.

[0042] Exemplarily, the material of the bracket 122 includes polyamide 66 and glass fiber, and the content of the glass fiber is 15%, so that on the premise of ensuring the appearance and overall strength, the overall weight of the headphone 10 can be effectively reduced.

[0043] It should be noted that PA66, also known as polyamide 66 or nylon 66, is a thermoplastic resin, generally prepared by polycondensation of adipic acid and hexamethylenediamine. Usually, its mechanical strength and hardness are very high, and its rigidity is very large.

[0044] The ear shell 121 has an accommodation cavity 121a and an opening 121b inside. Among them, the opening 121b can be arranged at one end of the ear shell 121 close to the head-mounted part 11.

[0045] The opening 121b communicates with the accommodation cavity 121a, and the bracket 122 is arranged in the accommodation cavity 121a. Part of the bracket 122 can be arranged in the accommodation cavity 121a, and part of the bracket 122 extends out of the accommodation cavity 121a through the opening 121b and is connected to the connecting member 123; or the whole bracket 122 can be arranged in the accommodation cavity 121a, and the connecting member 123 extends into the accommodation cavity 121a from outside the ear shell 121 and is connected to the connecting part 122a of the bracket 122.

[0046] The bracket 122 includes a connecting portion 122a and rotating portions 122b disposed at both ends of the connecting portion 122a. One end of each of the two rotating portions 122b is connected to the connecting portion 122a, and the other end extends at least along a first direction and is rotatably connected to both sides of the ear shell 121 along a second direction. That is to say, the bracket 122 can extend from the opening 121b to both side walls of the ear shell 121 along the width direction within the accommodation cavity 121a and form a rotational connection with the side walls.

[0047] It should be noted that the other end of the rotating portion 122b extends at least along the first direction, which means that the other end of the rotating portion 122b can extend along other directions in addition to the first direction, such as the second direction.

[0048] As Figure 4 shown, the first axis is represented by a, and the central axis of the ear shell 121 parallel to the first direction is represented by b.

[0049] One end of the connecting member 123 is connected to the headgear 11, and the other end is connected to the connecting portion 122a, which means that the headgear 11 and the bracket 122 are connected by the connecting member 123.

[0050] It should be noted that the first axis is the connection line of the positions where the two rotating portions 122b are respectively rotatably connected to the ear shell 121. The ear shell 121 can rotate relative to the bracket 122 about the first axis. In this way, the side of the ear cup assembly 12 facing the wearer can automatically adapt to the head shape and ears of the wearer, fit better with the ears and head of the wearer, thereby improving the adaptability and wearing stability of the ear cup assembly 12. At the same time, the sealing between the ear cup assembly 12 and the ears is better, improving the noise reduction effect and enhancing the user experience of the wearer.

[0051] The first axis is parallel to the second direction. That is to say, the positions where the two rotating portions 122b are respectively rotatably connected to the ear shell 121 are symmetric with respect to the central axis parallel to the first direction on the ear shell 121.

[0052] The direction of the connection line between both ends of the headgear 11 is the third direction, and the third direction can also be understood as the direction of the connection line between the two ears after the headphone 10 is worn.

[0053] The headphone 10 provided by the embodiment of the present application has a rotating part 122b of the bracket 122 arranged to extend at least along a first direction and rotatably connected to both sides of the ear cup 121 along a second direction. The connection line of the two positions where the two rotating parts 122b are respectively rotatably connected to the ear cup 121 forms a first axis, so that the ear cup 121 can rotate relative to the bracket 122 around the first axis, and the ear cup 121 can be rotated and adjusted within a certain angle range. Moreover, the first axis is parallel to the second direction and intersects with the first direction and the third direction. In this way, the side of the ear cup assembly 12 facing the wearer can automatically adapt to the head shape and ears of the wearer, fit more closely with the ears and head of the wearer, thereby improving the adaptability and wearing stability of the ear cup assembly 12, enhancing the noise reduction effect, and improving the use experience of the wearer. On the other hand, by arranging the bracket 122 in the accommodation cavity 121a, the appearance of the headphone 10 can be made more beautiful, and the situation that dust is easily accumulated and hair is easily caught between the external bracket 122 and the housing 1211 can be improved.

[0054] In some embodiments, please refer to Figures 3 to 4 , the first axis passes through the center of the ear cup 121 along the first direction.

[0055] It should be noted that the center of the ear cup 121 along the first direction can be the approximate center of the ear cup 121 along the first direction. When the deviation dimension of the position of the approximate center relative to the complete center in the first direction accounts for a ratio within the range of ±10% of the dimension of the ear cup 121 along the first direction, it can be regarded that the first axis passes through the center of the ear cup 121 along the first direction.

[0056] It can be understood that the headphone 10 is mainly fixed with the ear cup assembly 12 that fits with the ears during wearing as the clamping point.

[0057] By making the first axis pass through the center of the ear cup 121 along the first direction, the ends of the rotating parts 122b far from the connecting part 122a are respectively rotatably connected to the middle positions of both sides of the ear cup 121 in the width direction in the length direction. Thus, when the wearer wears the headphone 10, due to the certain clamping force at both ends of the headband 11, the ear cup assemblies 12 at both ends of the headband 11 can be clamped on both sides of the wearer's head. At this time, the headband 11 applies a certain acting force to the ear cup 121 through the connecting piece 123 and the bracket 122, and the two acting positions of the acting force are the positions of the rotational connection. The acting force application positions are on the central axis of the ear cup 121 in the length direction, so that the acting point of the resultant force of the acting force received by the ear cup 121 is close to the center position of the ear cup 121. Therefore, when the ear cup assembly 12 contacts the head and ears, the acting force transmitted from the ear cup 121 to the ears and head is more uniform, and the ear cup assembly 12 fits more stably with the ears of the wearer, thereby improving the experience of long-term wearing.

[0058] In some embodiments, referring to Figures 3 to 4 , one end of the rotating part 122b away from the connecting part 122a extends along the second direction and forms a first rotating shaft 122c. A limiting groove 121c is formed on the wall of the accommodating cavity 121a. The first rotating shaft 122c is rotationally engaged with the limiting groove 121c.

[0059] It can be understood that first rotating shafts 122c are formed at one ends of the two rotating parts 122b away from the connecting part 122a, and the central axes of the two first rotating shafts 122c coincide with the first axis. At the same time, a limiting groove 121c cooperating with the first rotating shaft 122c is formed on the wall of the accommodating cavity 121a. The first rotating shaft 122c can extend into the limiting groove 121c and rotate, so that the ear shell 121 can rotate relative to the bracket 122 around the first axis, and it is beneficial to improve the rotation stability.

[0060] Exemplarily, the cross-section of the limiting groove 121c is circular.

[0061] Exemplarily, the limiting groove 121c is integrally formed by the cavity wall or formed by combining a split structure.

[0062] In some embodiments, the angle range within which the ear shell 121 can rotate relative to the bracket 122 around the first axis is 12° - 18°. For example, the angle range can be 12°, 13°, 15°, 16°, 17° or 18°, etc., which is not limited here.

[0063] It should be noted that after the head-mounted earphone 10 is worn, generally the ear cup assembly 12 contacts the ears on both sides of the head. At the same time, the connection line between the two ends of the headband 11, that is, the connection line between the ears on both sides of the head, is the third direction. Therefore, it can be considered that in an ideal situation, the contact surface between the ear cup assembly 12 and the ear is approximately or completely perpendicular to the third direction.

[0064] Exemplarily, if the angle range within which the ear shell 121 can rotate relative to the bracket 122 around the first axis is 15°, then the ear shell 121 can rotate 7.5° forward and 7.5° backward relative to the bracket 122 around the first axis based on the contact surface between the ear cup assembly 12 perpendicular to the third direction and the ear.

[0065] Here, by setting the angle range within which the ear shell 121 can rotate relative to the bracket 122 around the first axis to be 12° to 18°, the automatic adaptive adjustment of the ear shell 121 in one rotation direction is realized, improving the adaptability to different head circumferences and ear shapes. On the other hand, limiting the angle range of rotation can reduce the space inside the ear shell 121 for avoiding the bracket 122, thereby reducing the size of the ear shell 121.

[0066] In some embodiments, referring to Figures 3 to 4, the bracket 122 is U-shaped, C-shaped or V-shaped.

[0067] By setting the bracket 122 to be U-shaped, C-shaped or V-shaped, the bracket 122 can avoid other components or the internal structure inside the ear shell 121, thereby preventing interference between the ear shell 121 and the bracket 122 during the rotation of the ear shell 121. At the same time, setting the bracket 122 to be U-shaped, C-shaped or V-shaped can improve the structural strength of the bracket 122.

[0068] In some embodiments, please refer to Figures 3 to 5 , the ear shell 121 includes an outer shell 1211 and an inner shell 1212. The outer shell 1211 is connected to the inner shell 1212 to define a receiving cavity 121a. In the first direction, the thickness of the outer shell 1211 gradually decreases from the middle to both ends.

[0069] In the first direction, the thickness of the outer shell 1211 gradually decreases from the middle to both ends, thereby making the appearance of the ear shell 121 more beautiful and reducing the occupied space of the ear shell 121.

[0070] Exemplarily, both ends of the outer shell 1211 in the first direction are arc-shaped or beveled.

[0071] In some embodiments, please refer to Figures 3 to 4 , the connecting member 123 is formed with a limiting surface 123a facing the outer shell 1211. The outer wall of the outer shell 1211 can abut against the limiting surface 123a to limit the rotation of the ear shell 121.

[0072] Wherein, the limiting surface 123a can be designed by copying the outer wall of the outer shell 1211, so that the outer wall of the outer shell 1211 fits better with the limiting surface 123a.

[0073] By forming the limiting surface 123a facing the outer shell 1211 on the connecting member 123, the outer wall of the outer shell 1211 can abut against the limiting surface 123a, thereby being able to limit the rotation of the ear shell 121 during the rotation around the first axis.

[0074] In some embodiments, please refer to Figures 3 to 4 , the inner wall of the outer shell 1211 is formed with a limiting portion 1211a, and the side of the bracket 122 close to the outer shell 1211 can abut against the limiting portion 1211a to limit the rotation of the ear shell 121.

[0075] It can be understood that since the bracket 122 is fixedly connected to the connecting member 123, one end of the outer shell 1211 close to the opening 121b along the first direction can rotate back and forth around the first axis between the limiting surface 123a of the connecting member 123 and the side of the bracket 122 close to the outer shell 1211. When the limiting portion 1211a on the inner wall of the outer shell 1211 abuts against the side of the bracket 122 close to the outer shell 1211, the ear shell 121 rotates around the first axis to the first position, and a gap can be formed between the outer wall of the outer shell 1211 and the limiting surface 123a; when the outer wall of the outer shell 1211 abuts against the limiting surface 123a, the gap between the outer wall of the outer shell 1211 and the limiting surface 123a is zero, and the ear shell 121 rotates around the first axis to the second position. The first position and the second position define the maximum angle at which the ear shell 121 can rotate relative to the bracket 122 around the first axis.

[0076] It should be noted that the gap range between the outer wall of the outer shell 1211 and the limiting surface 123a is related to the shell thickness of the outer shell 1211, the size of the ear shell 121, the position of the first axis, etc., and is not specifically limited here. The gap range between the outer wall of the outer shell 1211 and the limiting surface 123a only needs to satisfy that the ear shell 121 can rotate relative to the bracket 122 around the first axis by a set angle.

[0077] In some embodiments, please refer to Figures 3 to 4 , the headgear 11 includes a headband body 111 and a connecting shaft 112. One end of the connecting shaft 112 is connected to the headband body 111, and the other end extends along the fourth direction and is rotationally engaged with the connecting member 123. The connecting member 123 can rotate relative to the connecting shaft 112 around the second axis. The second axis is parallel to the fourth direction.

[0078] One end of the connecting shaft 112 is connected to the headband body 111, which can be a fixed connection or other connection forms.

[0079] The other end of the connecting shaft 112 extends along the fourth direction and is rotationally engaged with the connecting member 123. Among them, the fourth direction can be the height direction of the headband body 111. The rotational engagement between the connecting shaft 112 and the connecting member 123 can be such that one of them forms a rotating shaft, and the other forms a groove that rotates in cooperation with the rotating shaft.

[0080] Exemplarily, the second axis is the central axis of the connecting shaft 112.

[0081] As Figure 4 shown, the second axis is represented by c.

[0082] The connecting member 123 can rotate relative to the connecting shaft 112 around the second axis, that is to say, the connecting member 123 can drive other parts of the earphone assembly 12 to rotate relative to the connecting shaft 112 around the second axis.

[0083] By connecting one end of the connecting shaft 112 to the headband body 111 and the other end extending along the fourth direction and rotatingly cooperating with the connecting member 123, the connecting member 123 can rotate relative to the connecting shaft 112 around the second axis, so that the ear shell 121 can be rotated and adjusted in another rotation direction, thereby further improving the adaptability and wearing stability of the earmuff assembly 12.

[0084] For some examples, see Figures 3 to 4 , the angle range of the connecting member 123 that can rotate around the second axis relative to the connecting shaft 112 is 30°-105°. For example, the angle range of the connecting member 123 that can rotate around the second axis relative to the connecting shaft 112 is 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100° or 105°, etc., which is not limited here.

[0085] It should be noted that the plane where the ear shell 121 and the wearer's contact surface are located is perpendicular to the third direction and is defined as the initial position. Looking from the headgear 11 toward the earmuff assembly 12 along the fourth direction, the counterclockwise rotation angle of the connecting member 123 around the second axis relative to the connecting shaft 112 is negative, and the clockwise rotation angle is positive.

[0086] Exemplarily, when the rotation angle range of the connecting member 123 is 30°, the rotation range of the connecting member 123 can be 15° clockwise and counterclockwise respectively based on the initial position. Of course, the rotation range of the connecting member 123 clockwise and counterclockwise based on the initial position can also be different, for example, -10° and +20°.

[0087] Exemplarily, based on the initial position, the connector 123 can rotate 90° clockwise or counterclockwise around the second axis relative to the connecting shaft 112 , thereby increasing the rotation range of the earmuff assembly 12 and increasing the usage scenarios of the headset 10 .

[0088] For some examples, see Figures 1 to 6 , the angle between the first direction and the fourth direction is 10°-18°. For example, the angle between the first direction and the fourth direction is 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17° or 18°, etc., which is not limited here.

[0089] like Figure 2 and Figure 4 As shown, the angle between the first direction and the fourth direction is α, that is, the angle between the length direction of the ear shell 121 and the height direction of the headgear 11, wherein the height direction of the headgear 11 can be parallel to the line connecting the connecting portion 122a and the center of the ear shell 121.

[0090] That is to say, by offsetting the connecting portion 122a of the bracket 122 towards the ear shell 121 in the second direction, a certain included angle can be formed between the length direction of the ear shell 121 and the height direction of the headgear 11.

[0091] The first direction and the fourth direction form a certain included angle, so that after the wearer wears the headgear 11, it can be centered on the top of the head, making the wearing of the headset 10 more stable.

[0092] Exemplarily, the included angle between the first direction and the fourth direction is 15°. Thus, when the wearer wears the headset 10, the end of the ear shell 121 close to the headgear 11 along the first direction faces the back of the head, and the end of the ear shell 121 far from the headgear 11 along the first direction faces the face, making the end of the ear shell 121 far from the headgear 11 closer to the mouth, which is beneficial for the microphone to collect the sound emitted by the wearer.

[0093] In some embodiments, please refer to Figures 1 to 6 , both ends of the headband body 111 are rotationally matched with the end of the connecting shaft 112 far from the connecting member 123. The connecting shaft 112 can rotate relative to the headband body 111 around the third axis. The third axis intersects with the fourth direction.

[0094] Exemplarily, the third axis is perpendicular to the fourth direction.

[0095] As Figure 4 shown, the third axis is represented by d.

[0096] It can be understood that the connecting shaft 112 extends along the fourth direction, one end forms a rotational fit with the connecting member 123 around the second axis, that is, its own extension direction and the connecting member 123, and the other end rotates with the headband body 111 around the third axis.

[0097] As Figure 6 shown, the connecting shaft 112 can rotate relative to the headband body 111 around the third axis, which means that the connecting shaft 112 can drive the earphone assembly 12 to rotate towards the middle area of the headband body 111 along the third direction.

[0098] Exemplarily, after the two earphone assemblies 12 rotate towards the middle area of the headband body 111 along the third direction, the two earphone assemblies 12 can be overlapped along the fourth direction.

[0099] Exemplarily, after the two earphone assemblies 12 rotate towards the middle area of the headband body 111 along the third direction, the two earphone assemblies 12 can be coplanar along the third direction.

[0100] Here, by rotating the two ends of the headband body 111 with the end of the connecting shaft 112 away from the connecting member 123, the connecting shaft 112 can rotate relative to the headband body 111 around the third axis, so that the earmuff assembly 12 can be folded toward the headgear 11 for easy storage.

[0101] In some embodiments, the earmuff assembly 12 includes a first rubber member, and the first rubber member is sleeved on the first rotating shaft 122c.

[0102] Therefore, by sleeve-mounting the first rubber member on the first rotating shaft 122 c , the damping feeling when the ear shell 121 rotates relative to the bracket 122 around the first axis can be increased.

[0103] In some embodiments, one end of the connecting shaft 112 away from the headband body 111 extends along the fourth direction and forms a second rotating shaft 112a. The connecting member 123 forms a rotating groove that matches the second rotating shaft 112a. The earmuff assembly 12 includes a second rubber member. The second rubber member is sleeved on the second rotating shaft 112a.

[0104] Exemplarily, the second rubber member is a silicone ring.

[0105] Exemplarily, a protrusion is formed on the second rotating shaft 112a, and two limiting structures are formed on the rotating groove. The protrusion of the second rotating shaft 112a can follow the rotation of the second rotating shaft 112a and move between the two limiting structures. When the protrusion of the second rotating shaft 112a moves to any one of the limiting structures, the limiting structure can abut against the protrusion, thereby limiting the rotation of the second rotating shaft 112a, thereby improving the situation where the internal wiring harness of the headset 10 is prone to excessive rotation and cause damage to the wiring harness.

[0106] Therefore, by arranging the second rubber member on the second rotating shaft 112 a , the damping feeling when the connecting member 123 rotates around the second axis can be increased, and the gap between the components during the assembly process can be reduced.

[0107] In some embodiments, the diameter of the first rotating shaft 122c ranges from 4 mm to 5.5 mm. For example, the diameter of the first rotating shaft 122c is 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5.0 mm, 5.2 mm or 5.5 mm, etc., which is not limited here.

[0108] Here, by setting the diameter range of the first rotating shaft 122c to 4mm-5.5mm, the situation that the first rotating shaft 122c is too small in diameter and thus lacks strength is improved. At the same time, it also avoids the situation that the first rotating shaft 122c is too large, which causes easy shrinkage during injection molding, and the first rotating shaft 122c has a large shape and position error, which causes the first rotating shaft 122c to rotate unevenly.
