[0026] In the description of the embodiments of this application, it should be noted that unless otherwise clearly specified and limited, the terms "communicate" and "connect" 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 this application can be understood according to specific situations.

[0027] An earphone assembly generally includes an earphone and a charging case. The charging case is used to place the earphone and serves the functions of charging and storing the earphone. In the related art, generally, the charging case is designed to be in the shape of the outer contour of the earphone, resulting in inconvenient placement and removal of the earphone in the charging case and bringing an unpleasant experience to the user.

[0028] Based on the above situation, in the first aspect of the embodiments of the present application, a charging case 12 is provided. Please refer to Figures 1 to 4 , the charging case 12 includes a mounting seat 121. The mounting seat 121 has a receiving cavity 121a. Part of the cavity wall of the receiving cavity 121a protrudes to form a protruding portion 121b. The protruding portion 121b divides the receiving cavity 121a to form a profiling groove 1211a and a receiving groove 1211b. The sound generating unit 111 of the earphone 11 is disposed in the profiling groove 1211a. At least part of the connecting unit 112 of the earphone 11 is disposed in the receiving groove 1211b. One end of the mounting seat 121 in the first direction is provided with a first opening 121c communicating with the receiving cavity 121a, and one end of the mounting seat 121 in the second direction is provided with a second opening 121d communicating with the receiving cavity 121a. The first opening 121c and the second opening 121d are communicated, and the first direction intersects with the second direction.

[0029] It should be noted that the structure of the charging case 12 can be used to place any type of ear-hook or in-ear earphone.

[0030] Exemplarily, the structure of the charging case 12 is used to place a fully open wearable earphone.

[0031] The fully open wearable earphone, also known as an OWS (Open Wearable Stereo) earphone, adopts the air conduction method, and the main design concepts are "fully open" and "non-in-ear", ensuring the comfort of long-term wearing.

[0032] In the embodiments of the present application, the earphone 11 is taken as an example of a fully open wearable earphone for description.

[0033] It should be noted that the earphone 11 can be placed in the charging case 12 in scenarios such as insufficient battery power or non-use, so as to facilitate charging and storage.

[0034] Specifically, the mounting seat 121 is used to place the earphone 11, provides preliminary fixation for the earphone 11, and can charge the earphone 11.

[0035] Exemplarily, a battery is disposed in the mounting seat 121.

[0036] A part of the cavity wall of the accommodating cavity 121a protrudes to form a protruding part 121b, thereby dividing the accommodating cavity 121a into a profiling groove 1211a and a receiving groove 1211b. It means that the accommodating cavity 121a is an integral cavity, and the protruding part 121b is formed inside the cavity and divides the accommodating cavity 121a into the profiling groove 1211a and the receiving groove 1211b. That is to say, the remaining space of the accommodating cavity 121a except the profiling groove 1211a is the receiving groove 1211b, that is, the receiving groove 1211b is an open groove, so that when the user takes and places the earphone 11, the finger can extend into the receiving groove 1211b, thus making it more convenient to take and place the earphone 11. At the same time, the open-space receiving groove 1211b is also beneficial to the heat dissipation of the earphone 11, and can improve the situation that the earphone 11 overheats due to long-term charging, thereby shortening the service life of the battery of the earphone 11.

[0037] Here, the fact that the receiving groove 1211b is an open groove means that the remaining space of the accommodating cavity 121a except the profiling groove 1211a is the receiving groove 1211b, and no other partition walls or limiting structures are provided to limit other components of the earphone 11. In this way, it is beneficial to improve the space of the receiving groove 1211b.

[0038] Here, the cavity wall of the accommodating cavity 121a is a smooth curved surface, which not only improves the aesthetics but also is beneficial to making full use of the space inside the mounting seat 121; in addition, it can also minimize the dead corner area inside the accommodating cavity 121a, reduce the accumulation of dust and debris inside the accommodating cavity 121a, and facilitate cleaning.

[0039] Exemplarily, the protruding part 121b is smoothly connected to the cavity wall of the accommodating cavity 121a.

[0040] Exemplarily, the protruding part 121b forms at least part of the profiling groove 1211a. That is to say, the profiling groove 1211a can be formed only by the protruding part 121b, or the protruding part 121b and the cavity wall of the accommodating cavity 121a can jointly form the profiling groove 1211a.

[0041] Exemplarily, the first direction is the height direction of the mounting seat 121, the second direction is the width direction of the mounting seat 121, and the first direction is perpendicular to the second direction.

[0042] Exemplarily, the first opening 121c penetrates the top wall of one end of the mounting seat 121 along the first direction and extends to the side end of the mounting seat 121.

[0043] Exemplarily, the second opening 121d penetrates the side wall of one end of the mounting seat 121 along the second direction and extends to the top end of the mounting seat 121.

[0044] By providing a first opening 121c at one end of the mounting base 121 along the first direction and a second opening 121d at one end along the second direction, and at the same time, both the first opening 121c and the second opening 121d are in communication with the receiving cavity 121a. On the one hand, a finger can extend into the receiving groove 1211b from the first opening 121c, thus enabling more convenient taking and placing of the earphone 11. On the other hand, the user can sweep out the dust or debris in the receiving groove 1211b from the second opening 121d, which is beneficial to keeping the earphone 11 and the charging case 12 clean.

[0045] For the earphone assembly 10 provided by the embodiment of the present application, a protruding portion 121b is formed by protruding a part of the cavity wall of the receiving cavity 121a of the mounting base 121, so as to divide the overall groove of the receiving cavity 121a into a profiling groove 1211a and a receiving groove 1211b. At the same time, the mounting base 121 is provided with a first opening 121c and a second opening 121d that communicate with the receiving cavity 121a. That is to say, the remaining space in the receiving cavity 121a except for the profiling groove 1211a is the receiving groove 1211b, and the receiving groove 1211b is an open groove, enabling a finger to extend into the receiving groove 1211b from the first opening 121c when the user takes and places the earphone 11, thus enabling more convenient taking and placing of the earphone 11 and enhancing the user experience. On the other hand, the open space of the receiving groove 1211b is also beneficial to the heat dissipation of the earphone 11, which can improve the situation where the earphone 11 overheats due to long-term charging, thereby shortening the service life of the earphone 11 battery. On the other hand, the open design reduces the accumulation of dust and debris in the receiving groove 1211b, and the user can also sweep out the dust or debris in the receiving groove 1211b from the second opening 121d, which is beneficial to keeping the charging case 12 clean.

[0046] In some embodiments, please refer to Figures 1 to 3 , at least a part of the bottom wall of the receiving groove 1211b is smoothly connected to at least a part of the bottom wall of the second opening 121d.

[0047] It should be noted that the smooth connection means that at least a part of the bottom wall of the receiving groove 1211b and at least a part of the bottom wall of the second opening 121d are coplanar, that is, at least a part of the surfaces of the two bottom walls are flush. In this way, there is no protrusion or other obstacle between at least a part of the bottom wall of the receiving groove 1211b and at least a part of the bottom wall of the second opening 121d, enabling the receiving groove 1211b of the mounting base 121 to directly lead out to the second opening 121d along the second direction, making it more convenient for the user to directly sweep out the dust or debris in the receiving groove 1211b through the second opening 121d to clean the receiving groove 1211b, further reducing the possibility of the earphone 11 being contaminated.

[0048] In some embodiments, please refer to Figures 1 to 3, the charging case 12 includes a cover 122. The cover 122 includes a main cover 1221 and a front cover 1222 connected to the main cover 1221. When the charging case 12 is in a closed state, the main cover 1221 closes the first opening 121c, and the front cover 1222 closes the second opening 121d.

[0049] Exemplarily, the cover 122 is hingedly connected to one end of the mounting base 121 along the second direction away from the second opening 121d, so as to realize the opening and closing of the cover 122.

[0050] When the charging case 12 is in a closed state, the main cover 1221 closes the first opening 121c, and the front cover 1222 closes the second opening 121d, thereby protecting the earphone 11 and preventing dust or foreign objects from entering the accommodating cavity 121a.

[0051] In some embodiments, please refer to Figures 1 to 3 , the mounting base 121 has a first side wall 121f and a second side wall 121g oppositely arranged along the third direction. The first direction, the second direction, and the third direction intersect. At least part of the second opening 121d is formed along the third direction on the first side wall 121f; and / or, at least part of the second opening 121d is formed along the third direction on the second side wall 121g.

[0052] Exemplarily, the third direction may be the length direction of the mounting base 121, and the third direction is perpendicular to the first direction and the second direction pairwise.

[0053] It should be noted that at least part of the second opening 121d is formed along the third direction on the first side wall 121f, which means that a notch is formed at one end of the first side wall 121f along the second direction, and one end of the second opening 121d extends to the first side wall 121f and communicates with the notch.

[0054] Similarly, at least part of the second opening 121d is formed along the third direction on the second side wall 121g, which means that a notch is also formed at one end of the second side wall 121g along the second direction, and one end of the second opening 121d extends to the second side wall 121g and communicates with the notch.

[0055] Among them, at least part of the second opening 121d may be formed only on the first side wall 121f or the second side wall 121g along the third direction, or may be formed on both the first side wall 121f and the second side wall 121g along the third direction, which is not limited herein.

[0056] In this way, the accommodating cavity 121a of the mounting base 121 can be further opened, making it more convenient to take and place the earphone 11, and facilitating the cleaning of the accommodating cavity 121a. At the same time, the front cover 1222 also correspondingly bends and extends along the second direction to close the second opening 121d.

[0057] Exemplarily, at least a part of the first side wall 121f is smoothly connected to at least a part of the side wall of the second opening 121d, and at least a part of the second side wall 121g is smoothly connected to at least a part of the side wall of the second opening 121d. In this way, there are no protrusions or other obstacles between the first side wall 121f and the side wall of the second opening 121d, and between the second side wall 121g and the side wall of the second opening 121d, so that the accommodating groove 1211b of the mounting seat 121 can directly lead out to the second opening 121d along the second direction, which is more convenient for the user to clean the accommodating groove 1211b and further reduces the possibility of the earphone 11 being contaminated.

[0058] In some embodiments, please refer to Figures 1 to 3 , the number of the profiling grooves 1211a is two, and the two profiling grooves 1211a are arranged at intervals along the third direction.

[0059] The number of the profiling grooves 1211a is two, corresponding to the case where the number of the earphones 11 in the earphone assembly 10 is two.

[0060] The two profiling grooves 1211a are arranged at intervals along the third direction, that is, the two profiling grooves 1211a for placing the sound generating units 111 are arranged along the third direction and are spaced apart by a certain distance, so that there is enough space between the profiling grooves 1211a for placing the sound generating units 111 of the two earphones 11 to place other parts of the earphones 11.

[0061] In some embodiments, the accommodating groove 1211b is provided with a stacking area between the two profiling grooves 1211a, and the connecting units 112 of the two earphones 11 can be stacked in the stacking area.

[0062] Exemplarily, the distance between the two profiling grooves 1211a is 15 mm - 25 mm, and for example, it can be 15 mm, 18 mm, 20 mm, 22 mm or 25 mm, etc.

[0063] It can be understood that considering that the user can grab the connecting units 112 of the two earphones 11 simultaneously through the fingers from the stacking area of the accommodating groove 1211b to take out the two earphones 11 simultaneously, between the two profiling grooves 1211a, that is, the stacking area, in addition to shortening the distance along the third direction, thereby reducing the size of the charging case 12 in the third direction to realize the stacking of the connecting units 112, there is also enough space to avoid the fingers and facilitate the fingers to grab the connecting units 112 of the two earphones 11.

[0064] In some embodiments, please refer to Figures 1 to 4 , a part of the protruding portion 121b sinks to form an avoidance groove 121e, and the avoidance groove 121e is used to avoid the connecting unit 112.

[0065] That is to say, the groove wall of the profiling groove 1211a sinks along a partial area in the first direction to form a notch, namely the avoidance groove 121e. The connecting unit 112 is connected to the sound generating unit 111 in the profiling groove 1211a through the avoidance groove 121e, so that the whole earphone 11 is more matched with the mounting seat 121 and more closely attached to the mounting seat 121, thereby reducing the size of the charging case 12 in the first direction.

[0066] In some embodiments, please refer to Figure 1 , the sound generating unit 111 is attached to the groove wall of the profiling groove 1211a.

[0067] Here, by attaching the sound generating unit 111 to the groove wall of the profiling groove 1211a, that is, the profiling groove 1211a is correspondingly designed according to the outer contour and key stress points of the sound generating unit 111, the shape of the groove wall of the profiling groove 1211a is more closely attached to a specific part of the earphone 11, thereby forming a tendency to tightly wrap the sound generating unit 111. At the same time, when the earphone 11 is placed in the mounting seat 121, the groove wall of the profiling groove 1211a can contact the sound generating unit 111 as much as possible, providing uniform and strong support, thereby restricting the movement of the sound generating unit 111 in multiple directions, improving the situation that the cooperation between the sound generating unit 111 and the profiling groove 1211a of the charging case 12 is too loose or too tight, and enhancing the stability of the earphone 11 fixed in the charging case 12.

[0068] In some embodiments, the ratio range of the size of the profiling groove 1211a in the first direction to the size of the sound generating unit 111 in the first direction is 20%-30%. Exemplarily, the ratio of the sizes is 20%, 22%, 24%, 26%, 28% or 30%, etc., which is not limited herein.

[0069] By setting the ratio range of the size of the profiling groove 1211a in the first direction to the size of the sound generating unit 111 in the first direction to 20%-30%, the depth of the profiling groove 1211a can limit the sound generating unit 111 of the earphone 11 in the second and third directions to a certain extent, and at the same time, it is also convenient for the user to take out the earphone 11 from the mounting seat 121. At the same time, the area where the profiling groove 1211a wraps the sound generating unit 111 is made as small as possible, which is more conducive to the heat dissipation of the earphone 11.

[0070] In some embodiments, please refer to Figures 1 to 4 , a part of the sound generating unit 111 protrudes to form a sound generating part 111a, and a part of the groove wall of the profiling groove 1211a is recessed to form a first groove 1211c, and the sound generating part 111a is arranged in the first groove 1211c.

[0071] Exemplarily, the sound generating part 111a is in the shape of a boss.

[0072] It should be noted that the shape of the first groove 1211c is designed corresponding to the outer contour and main stress points of the sound generating part 111a, so that the shape of the groove wall of the first groove 1211c fits better with the sound generating part 111a. Therefore, when the earphone 11 is placed in the mounting seat 121, the groove wall of the first groove 1211c can contact the sound generating part 111a as much as possible, providing uniform and strong support, so that the sound generating part 111a is fixed more stably in the charging case 12.

[0073] In some embodiments, referring to Figures 1 to 4 , the mounting seat 121 includes a first housing 1211, a second housing 1212 and a first magnetic member. The first housing 1211 is formed with a profiling groove 1211a and a receiving groove 1211b. The first housing 1211 and the second housing 1212 jointly define a receiving space. A first magnetic member is disposed on a side of the first housing 1211 facing away from the profiling groove 1211a. The sound generating unit 111 includes a second magnetic member. The sound generating unit 111 and the profiling groove 1211a are magnetically coupled by the first magnetic member and the second magnetic member.

[0074] The sound generating unit 111 and the profiling groove 1211a are magnetically coupled by the first magnetic member and the second magnetic member, so that when the earphone 11 is placed in the charging case 12, the first magnetic member and the second magnetic member can attract each other, further enhancing the connection stability between the earphone 11 and the charging case 12.

[0075] It should be noted that the first magnetic member can be disposed in the receiving space, or on the surface of the profiling groove 1211a, or on a side of the first housing 1211 facing away from the profiling groove 1211a.

[0076] Similarly, the second magnetic member can be disposed in the internal space of the sound generating unit 111, or on the outer surface of the sound generating unit 111, or on a side of the sound generating unit 111 facing away from the outer surface.

[0077] Exemplarily, the sound generating unit 111 includes a main housing 1111 and a charging member 1113. A part of the sound generating unit 111 protrudes to form a sound generating part 111a. The mounting seat 121 is provided with a charging ejector pin protruding from the groove wall of the profiling groove 1211a. The distribution positions of the first magnetic members are respectively near the charging ejector pin and the first groove 1211c, wherein there can be one or more first magnetic members at each distribution position of the first magnetic members; correspondingly, the distribution positions of the second magnetic members are respectively near the charging member 1113 and the sound generating part 111a, and there can be one or more second magnetic members at each distribution position of the second magnetic members. In this way, the sound generating unit 111 of the earphone 11 and the profiling groove 1211a are attracted to each other by at least three magnetic members, thereby improving the fixing effect of the sound generating unit 111 of the earphone 11 in the profiling groove 1211a and making the charging of the earphone 11 more stable and reliable.

[0078] In some embodiments, referring to Figure 4 , the sound generating unit 111 includes a main housing 1111, a buffer member 1112, and a charging member 1113. The charging member 1113 and the buffer member 1112 are both disposed in the main housing 1111, and the buffer member 1112 surrounds the periphery of the charging member 1113.

[0079] It should be noted that the main housing 1111 is an outer shell that wraps around to protect the parts installed inside.

[0080] Exemplarily, the buffer member 1112 can be made of a soft buffer material, such as silica gel or rubber.

[0081] Exemplarily, the buffer member 1112 is an annular silica gel pad.

[0082] The charging member 1113 is installed on the main housing 1111 and is used to form an electrical connection with the mounting base 121, so as to charge the battery built in the earphone 11.

[0083] Exemplarily, the charging member 1113 is a charging copper post.

[0084] It should be noted that the charging member 1113 is disposed inside the main housing 1111 and is exposed outside the main housing 1111 through an opening. Correspondingly, the mounting base 121 is provided with a charging ejector pin protruding from the groove wall of the profiling groove 1211a, so as to more conveniently form an electrical connection between the earphone 11 and the mounting base 121. At the same time, the charging ejector pin can also generate a certain limit with the opening of the main housing 1111 for exposing the charging member 1113, making the electrical connection more stable, improving the charging stability of the charging case 12 for the earphone 11, and shortening the charging time.

[0085] The buffer member 1112 surrounds the periphery of the charging member 1113. That is to say, the buffer member 1112 is disposed outside the opening of the main housing 1111 for exposing the charging member 1113. On the one hand, it can protect the charging member 1113. On the other hand, when the earphone 11 is worn, the buffer member 1112 faces the ear, so it has a certain anti-slip effect and improves the situation that the earphone 11 is prone to slip off the ear.

[0086] In some embodiments, referring to Figures 2 to 4 , the profiling groove 1211a is recessed to form a second groove 1211d, and the buffer member 1112 is located in the second groove 1211d.

[0087] It should be noted that the second groove 1211d is designed corresponding to the outer contour and key stress points of the buffer member 1112, so that the shape of the groove wall of the second groove 1211d fits better with the buffer member 1112 part of the earphone 11. Thus, when the earphone 11 is placed in the charging case 12, the buffer member 1112 contacts with the second groove 1211d, increasing the frictional resistance between the earphone 11 and the mounting seat 121. On the other hand, it can also absorb external impacts and vibrations to a certain extent, providing additional protection for the earphone 11. At the same time, the second groove 1211d can limit the buffer member 1112 to a certain extent, thus improving the situation that the earphone 11 shakes in the charging case 12.

[0088] In some embodiments, please refer to Figures 1 to 4 , a silica gel pressing strip 122a is provided on the main cover 1221. The connecting unit 112 includes a hanging part 1121 and a battery part 1122. The battery part 1122 is connected to one end of the hanging part 1121 away from the sound generating unit 111. In the closed state, the cover body 122 is closed, and the silica gel pressing strip 122a abuts against the battery part 1122.

[0089] In the closed state, since the accommodating groove 1211b is an open groove and no other partition walls or limiting structures are provided for limiting the charging part and the hanging part 1121 of the earphone 11, by providing the silica gel pressing strip 122a on the main cover 1221, the silica gel pressing strip 122a can abut against one end of the earphone 11 away from the sound generating unit 111, that is, the battery part 1122, so as to prevent one end of the earphone 11 away from the sound generating unit 111 from shaking in the charging case 12, improving the reliability and stability of the charging case 12 for fixing the earphone 11.

[0090] In this way, at one end along the second direction, the silica gel pressing strip 122a abuts against the battery part 1122, and at the other end along the second direction, the sound generating unit 111 is magnetically attached to the profiling groove 1211a, so as to improve the fixing reliability and stability of the charging case 12 for the earphone 11, and improve the situation that the earphone 11 is prone to shake and generate abnormal noises in the charging case 12.

[0091] The second aspect of the embodiments of the present application provides an earphone assembly 10. Please refer to Figures 2 to 3 , the earphone assembly 10 includes an earphone 11 and a charging case 12 provided in any embodiment of the present application, and the charging case 12 is used for placing the earphone 11. The earphone 11 includes a sound generating unit 111 and a connecting unit 112. The sound generating unit 111 is connected to the connecting unit 112.

[0092] It should be noted that, according to the working principle, earphones can generally be divided into air conduction earphones and bone conduction earphones; according to the way users wear earphones, they can generally be divided into over-ear earphones, ear-hook earphones and in-ear earphones.

[0093] The earphone 11 in the embodiment of the present application can be any type of ear-hook or in-ear earphone 11.

[0094] Exemplarily, the earphone 11 in the embodiment of the present application can be a fully open wearable earphone 11.

[0095] The earphone 11 includes a sound generating unit 111 and a connecting unit 112. The sound generating unit 111 is located on the front side of the ear in the wearing state, emits sound to the ear, and transmits the sound to the user.

[0096] Among them, the sound generating unit 111 can be in a long strip shape, a flat circular shape or other shapes.

[0097] The connecting unit 112 is used to hang the earphone 11 on the ear to realize the wearing of the earphone 11.

[0098] In the earphone assembly 10 provided by the embodiment of the present application, a protruding portion 121b is formed by protruding a part of the cavity wall of the accommodating cavity 121a of the mounting seat 121 of the charging case 12, so as to divide the whole groove of the accommodating cavity 121a into a profiling groove 1211a and a containing groove 1211b. At the same time, the mounting seat 121 is provided with a first opening 121c and a second opening 121d communicating with the accommodating cavity 121a. That is to say, the remaining space in the accommodating cavity 121a except the profiling groove 1211a is the containing groove 1211b. The containing groove 1211b is an open groove, so that when the user takes and places the earphone 11, the finger can extend into the containing groove 1211b from the first opening 121c, so that the earphone 11 can be taken and placed more conveniently, improving the user experience. On the other hand, the open space of the containing groove 1211b is also beneficial to the heat dissipation of the earphone 11, and can improve the situation that the earphone 11 overheats due to long-term charging, thereby shortening the service life of the battery of the earphone 11. On the other hand, the open design reduces the accumulation of dust and sundries in the containing groove 1211b, reduces the possibility of the earphone 11 being contaminated, and the user can sweep out the dust or sundries in the containing groove 1211b from the second opening 121d, which is beneficial to keeping the earphone 11 and the charging case 12 clean.

[0099] In some embodiments, please refer to Figure 1 , the second direction and the third direction define a first reference plane. When projected on the first reference plane, the projections of the connecting units 112 of the two earphones 11 have an overlapping area in the containing groove 1211b.

[0100] It should be noted that the second direction and the third direction define a first reference plane, which means that the first reference plane is parallel to the second direction and the third direction respectively.

[0101] Exemplarily, the third direction is perpendicular to the first direction and the second direction pairwise, and the first reference plane is a plane perpendicular to the first direction.

[0102] The projection of the connection unit 112 of the two earphones 11 has an overlapping area within the accommodation groove 1211b, which means that the connection units 112 of the two earphones 11 can be stacked within the accommodation groove 1211b, so as to reduce the size of the mounting base 121 in the third direction and make the earphone assembly 10 more compact.

[0103] In some embodiments, please refer to Figure 4 , the connection unit 112 includes a hanging part 1121. One end of the hanging part 1121 is connected to the sound generating unit 111. The hanging part 1121 can undergo elastic deformation under an external force, so that at least part of the hanging part 1121 can be stacked in the first direction.

[0104] The hanging part 1121 is used to cooperate with the auricle to hang the earphone 11 on the ear.

[0105] The hanging part 1121 can undergo elastic deformation under an external force, that is to say, the hanging part 1121 has a certain strain recovery property, so that the hanging part 1121 has a certain amount of deformation in the wearing state to increase the normal pressure of the hanging part 1121 on the ear and / or the head, thereby increasing the resistance to the earphone 11 falling off the ear. At the same time, when the two earphones 11 are successively placed into the charging case 12, since the sound generating units 111 of the two earphones 11 are magnetically attracted and fit with the profiling groove 1211a, the hanging parts 1121 of the two earphones 11 can be stacked in the first direction through elastic deformation.

[0106] Exemplarily, the hanging part 1121 includes a support member and a sleeve member.

[0107] Exemplarily, the support member is a memory wire, and the material of the sleeve member is liquid silicone.
