[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Headphones are an audio playback device mainly used for personal listening needs. They consist of a pair of conversion units that can receive electrical signals from a media player or receiver and convert these electrical signals into audible sound waves through speakers close to the ears.

[0037] With the continuous development of headphone technology, users have higher and higher requirements for the comfort and acoustic performance of headphones. Open-type headphones can reduce the pressure on the ear canal because they do not block the ear canal, and will not feel uncomfortable even if worn for a long time. At the same time, they help keep the ear canal ventilated and dry. This design also allows users to hear some external sounds while enjoying music, such as environmental noise, other people's voices, etc. This design not only improves the wearing comfort, because the ears will not feel squeezed, even if worn for a long time, there will be no discomfort; in addition, it also maintains connectivity with the outside world, which is convenient for communication. Therefore, this type of headphones is becoming more and more popular among consumers.

[0038] In the open-type headphone structure, there is a form in which the headphone is worn on the ear through an ear hook. This type of headphone structure includes an ear hook and a sound-emitting structure connected to the ear hook. In conventional designs, the ear hook and the ear shell of the sound-emitting structure are fixedly connected. In such a structure, the relative position of the sound-emitting port on the ear shell and the ear canal opening cannot be adjusted during wearing, which may result in the sound being unable to be accurately transmitted to the ear, affecting the sound performance and resulting in poor listening effect.

[0039] In the related art, in order to achieve the adjustable position of the sound outlet, open-type earphones have a relatively complex gear structure or hinge structure designed between the ear hook and the ear shell. This setting method requires the design of a larger structure on the ear shell to accommodate and install parts such as gears and hinges. This makes the overall structure of the earphone larger and increases the weight of the earphone. Wearing it for a long time may cause discomfort to the user's ears.

[0040] To solve the above problems, please refer to Figure 1 and Figure 2 The present application proposes an earphone 100, which is an open earphone and is in the form of air conduction. The earphone 100 includes a sound-generating component 10 and an ear hook 20 connected to the sound-generating component 10, and the ear hook 20 is a curved structure.

[0041] Among them, see Figures 3 to 5The sound-emitting component 10 includes an ear shell 11 and a speaker unit 12, wherein the material of the ear shell 11 can be plastic, metal, silicone, etc. And it can be constructed in a relatively flat form, so that after the earphone 100 is worn, the sound-emitting component 10 can fit the ear more closely, thereby improving the stability and comfort after wearing. A receiving cavity 11c is formed in the ear shell 11, and the speaker unit 12 is received in the receiving cavity 11c. A sound-emitting port 1111a is also provided on the ear shell 11. The sound-emitting port 1111a is an important component of the sound-emitting component of the earphone, which is responsible for directional output of the sound waves generated by the sound-emitting unit inside the earphone to the ear canal opening of the user. Therefore, the sound-emitting port 1111a in the embodiment of the present application is configured to at least partially cover the ear canal opening of the user. When the speaker unit 12 is working, the sound generated is propagated outward through the sound-emitting port 1111a.

[0042] The end of the ear hook 20 is connected to the ear shell 11. The ear hook 20 as a whole has a certain deformation ability, and its overall shape is adapted to the shape of the back of the auricle. In some embodiments, it may include a rod-shaped body made of plastic, and a memory metal wire is further embedded in the rod-shaped body. Through such a structural form, the ear hook 20 has better toughness and bending ability, which makes it easier to pull during wearing and is conducive to its own resetting.

[0043] The earphone 100 of the present application has a battery 42 that can power the speaker unit 12. The specific form of the battery is not limited. For example, a repeatedly chargeable and dischargeable lithium battery can be used, which makes the earphone 100 easy to use and carry.

[0044] In one structural form, the battery can be accommodated in the accommodating cavity 11c. In this case, the entire earphone 100 is divided into two parts. It can also be called a two-stage design. It can be understood that in the case of a two-stage design, the connection between the battery and the speaker unit 12 is relatively short, and the wiring is relatively simple. Of course, at this time, the overall mass of the earphone 100 is more concentrated on the sound-emitting component 10. At this time, in order to make the entire earphone 100 more stable during wearing, the length of the ear hook 20 can be extended accordingly. For example, the end of the ear hook 20 away from the sound-emitting component 10 can be extended to a position corresponding to the earlobe. In this way, the ear hook 20 has a larger contact area with the ear, so that the earphone 100 can be stably worn on the ear.

[0045] Please refer to Figure 6 and Figure 7 In another structural form, the earphone 100 includes not only the sound-emitting component 10 and the ear hook 20, but also a battery compartment 40, wherein: Fig.16 and Fig.17As shown, the battery compartment 40 includes a housing 41 and a battery 42 contained in the housing 41. That is, in this embodiment, the earphone 100 is provided with three parts, namely, the sound-emitting component 10, the ear hook 20 and the battery compartment 40, so that the earphone 100 is formed into a three-section structure. The battery compartment 40 is connected to the other end of the ear hook 20, that is, the end away from the sound-emitting component 10. Figure 7 The figure shows the earphone 100 mounted outside the ear of the user during actual wearing and use. It can be seen from the figure that during wearing, the ear hook 20 is mounted on the back of the auricle of the ear, the sound-emitting component 10 extends from the helix crus to the concha cavity, and the position of the sound-emitting port 1111a is matched to the ear canal opening, so that the sound emitted by the speaker unit 12 is propagated directionally to the ear canal opening through the sound-emitting port 1111a. The battery compartment 40 is located on the back of the auricle and corresponds to the earlobe position of the ear.

[0046] The three-stage structural design helps to distribute the weight of the earphone 100 more evenly, improves the comfort during wearing, and the independent battery compartment 40 is more convenient for maintenance. Of course, the independent battery compartment 40 also provides a larger installation space for the battery 42, so it is easier to design the battery 42 with a larger capacity, so that the endurance of the earphone 100 is also correspondingly stronger.

[0047] Furthermore, in order to achieve adjustable position of the sound outlet 1111a, in any of the above embodiments, an opening 11a and a guide groove 11b connected to the opening 11a are provided on the ear shell 11; the ear hook 20 includes an ear hook body 21 and a connecting member 22 connected to each other, the ear hook body 21 is passed through the opening 11a, the connecting member 22 is located in the guide groove 11b, and can slide along the guide groove 11b; and the earphone 100 further includes a limiting structure 30, the limiting structure 30 includes a first limiting portion 31 and a second limiting portion 32, the first limiting portion 31 is provided on one of the connecting member 22 and the ear shell 11, and the second limiting portion 32 is provided on the other of the connecting member 22 and the ear shell 11; the first limiting portion 31 and the second limiting portion 32 are elastically abutted against each other and can move relative to each other.

[0048] That is, the earphone 100 of the present application is provided with a connector 22 that is slidably connected in the guide groove, so that the user can adjust the position of the sound outlet 1111a on the ear shell 11 according to the shape and size of the individual auricle by sliding between the ear shell 11 and the connector 22 of the ear hook 20. In this way, the sound outlet 1111a on the ear shell 11 can be adjusted to a position that is as closely aligned with the user's ear canal opening as possible, thereby improving the acoustic performance of the earphone 100 and improving the user's listening effect.

[0049] Please refer to Figure 8 , Fig. 9 and Fig.10The ear shell 11 includes an outer shell 111 and a partition 112 arranged in the outer shell 111. The partition 112 and a part of the inner wall of the outer shell 111 define a guide groove 11b, and the partition 112 and another part of the inner wall of the outer shell 111 define a receiving cavity 11c. The above-mentioned opening 11a is formed on the outer shell 111.

[0050] To facilitate assembly, in some structural forms, the housing 111 includes a first shell 1113 and a second shell 1114 that are snap-fitted to each other. The snap-fit ​​design provides greater design flexibility, and the shape and size of the first shell 1113 and the second shell 1114 can be adjusted according to different functional requirements, and disassembly and assembly and maintenance are more convenient.

[0051] In order to improve the waterproof capability, an annular waterproof groove 11131 is circumferentially arranged at the edge of the first shell 1113, and an annular waterproof boss 11141 adapted to the annular waterproof groove 11131 is circumferentially arranged at the edge of the second shell 1114. After the first shell 1113 and the second shell 1114 are buckled together, the annular waterproof boss 11141 is inserted into the annular waterproof groove 11131, thereby effectively preventing external liquid from entering the accommodating cavity 11c. The internal components of the ear shell 11 can be better protected, reducing damage caused by moisture intrusion and extending the service life of the earphone 100. Of course, through the cooperation between the annular waterproof boss 11141 and the annular waterproof groove 11131, the entire ear shell 11 can be sealed at the joint, that is, the effect of hiding the joint is achieved, thereby enhancing the aesthetics of the ear shell 11.

[0052] It can be understood that in order to further enhance the tightness of the connection between the first shell 1113 and the second shell 1114 and improve the waterproof and sweat-proof function of the ear shell 11, the first shell 1113 and the second shell 1114 can be fixedly connected by ultrasonic welding or gluing. If the connection effect can be achieved, the connection method between the first shell 1113 and the second shell 1114 can also be other, and the present application does not impose any restrictions on this.

[0053] Please refer to Fig.11 The partition 112 may include two halves, and the two halves of the partition 112 are respectively connected to the inner walls of the first shell 1113 and the second shell 1114. After the first shell 1113 and the second shell 1114 are snapped together, the two halves of the partition 112 are spliced ​​together. Of course, the partition 112 may also be one, and is connected to the inner wall of one of the first shell 1113 and the second shell 1114. After the first shell 1113 and the second shell 1114 are snapped together, the partition 112 is sealed and abutted against the other of the first shell 1113 and the second shell 1114. In this way, the partition 112 and part of the inner wall surfaces of the first shell 1113 and the second shell 1114 can cooperate to define the above-mentioned guide groove 11b.

[0054] In the three-stage earphone 100, as Fig.11 , Fig.12 and Fig.13 As shown, the earphone 100 also includes a wire 50 and a sealing ring 60 sleeved on the outside of the wire 50. Since it is necessary to connect the speaker unit 12 in the accommodating cavity 11c with the battery 42 in the battery compartment 40 through the wire 50, a wire outlet hole 22a for the wire 50 to pass through can be opened on the connecting member 22, and a wire through hole 112a is opened on the partition 112 at a position opposite to the wire outlet hole 22a. The wire through hole 112a connects the accommodating cavity 11c and the guide groove 11b. The wire through hole 112a is used to guide the wire 50 from the accommodating cavity 11c through the guide groove 11b and through the wire outlet hole 22a into the ear hook body 21, and finally extends into the battery compartment 40. This wiring form can avoid the wiring in the earphone 100 from having many bends and being messy, and the connection between the wiring part and the speaker unit 12 is connected and arranged in the ear hook body 21 through the wire 50, and is effectively combined, which can also make the structure more compact.

[0055] In order to prevent the speaker unit 12 in the accommodating cavity 11c from being corroded by moisture and sweat, a sealing ring 60 is provided on the end of the wire 50 away from the battery compartment 40. The sealing ring 60 is embedded in the wire hole 112a to reduce the generation of assembly gap. The connection between the sealing ring 60 and the wire hole 112a can also provide buffering and support for the wire 50, avoiding the wire 50 from being easily scratched at the wire hole 112a, thereby ensuring the safety of the internal circuit of the earphone 100 and preventing potential short circuit or damage.

[0056] Furthermore, an annular groove 60a is provided on the outer wall of the sealing ring 60, and an annular protrusion matching the annular groove 60a is provided on the inner wall of the wire hole 112a, so that the sealing ring 60 and the wire hole 112a form a tighter sealing connection, effectively preventing moisture, dust and other foreign matter from entering the interior of the earphone 100. The strengthened sealing connection helps to improve the waterproof and sweat-proof level of the earphone 100, making it more suitable for use in watery or humid environments.

[0057] Exemplarily, the sealing ring 60 can be a plastic water-stop (SR) sealing ring 60, which can provide good sealing performance in different working environments, can effectively prevent the inflow of external fluids whether in static or dynamic applications, and has strong corrosion resistance, will not be easily damaged and aged, and can extend the service life of the earphone 100.

[0058] The ear hook body 21 is a rod-shaped structure, including a rod-shaped body made of plastic material, a memory metal wire is arranged in the rod-shaped body of the ear hook body 21, and the connecting piece 22 can be made of the same material as the rod-shaped body of the ear hook body 21, and is produced by integral injection molding. Among them, in the three-stage structure, the end of the ear hook body 21 away from the ear shell 11 is connected to the cover 41 of the battery compartment 40. Among them, the rod-shaped body of the ear hook body 21 can be made of thermoplastic polyurethane (TPU) soft glue material, which is more comfortable for users to wear and will not cause ear pain after wearing for a long time; the connecting piece 22 can be made of acrylonitrile-butadiene-styrene plastic (ABS) hard glue material, so that its structural strength is higher and the rotation is smoother. The ear hook body 21 and the connecting piece 22 are made into one piece by secondary injection molding, which increases the connection strength between the two. Of course, in other structural forms, the connecting member 22 and the ear hook body 21 can also be a split structural form, and the connecting member 22 is fixed as a whole by bonding, welding, etc., or fixed as a whole by other connection forms such as threaded connection and snap connection. This application does not impose any restrictions on this.

[0059] Further, the guide groove 11b of the present application is extended along the circumference of the ear shell 11, and the two ends of the guide groove 11b are respectively provided with a first limiting surface and a second limiting surface, and the connecting member 22 slides between the first limiting surface and the second limiting surface, and the first limiting surface and the second limiting surface can provide a clear adjustment range for the sliding of at least part of the ear hook 20, ensuring that the user will not exceed the effective use limit when adjusting the earphone 100. In this embodiment, the opening length of the opening 11a is smaller than the distance between the first limiting surface and the second limiting surface, and the length dimension of the connecting member 22 is larger than the opening length dimension of the opening 11a, so that the design can also prevent the connecting member 22 from sliding out of the guide groove 11b. It can be understood that the above design of the length dimension of the connecting member 22 being larger than the opening length dimension of the opening 11a is only a feasible way to prevent the connecting member 22 from sliding out of the opening 11a. In other designs, it can also be that when the connecting member 22 can be located on the first limiting surface and the second limiting surface, the width dimension of the connecting member 22 is larger than the width dimension of the opening 11a, or other limiting structures are added.

[0060] To further describe the positional relationship between the sound outlet 1111a and the opening 11a on the ear shell 11, the outer surface of the housing 111 can be further divided into a contact surface 1111 and a side surface 1112 (eg, Figure 6 ), the contact surface 1111 is the surface that contacts the ear when the earphone 100 is worn, and the side surface 1112 is connected to the periphery of the contact surface 1111. The side surface 1112 does not contact the ear when the earphone 100 is worn. In the case where the ear shell 11 is designed as a flat structure, the side surface 1112 can also be considered as the surface of the ear shell 11 extending in the thickness direction. For example, Fig. 9 and Fig.10 As shown, the sound outlet 1111a is provided on the first shell 1113, the abutting surface 1111 is the surface of the first shell 1113 provided with the sound outlet 1111a, and the side surface 1112 is defined by the first shell 1113 and the second shell 1114. The sound outlet 1111a is provided on the abutting surface 1111, and the sound outlet 1111a is located on the abutting surface 1111 to ensure that the sound is directly transmitted to the user's ear canal when the earphone 100 is worn, thereby reducing the loss of the sound during the propagation process. The opening 11a is provided on the side surface 1112, so that the user can more easily operate the ear hook 20 exposed outside the opening 11a, drive the connecting member 22 in the guide groove 11b to slide, and during the adjustment process, the connection position between the ear hook 20 and the ear shell 11 is not easy to interfere with the user's ear skin.

[0061] Furthermore, at least part of the abutting surface 1111 is in a truncated cone structure and defines a sound outlet 1111a on the truncated cone structure. The truncated cone structure can make the sound outlet 1111a fit the ear canal opening more closely, forming a certain degree of sealing and positioning effect, thereby enhancing the low-frequency response. The truncated cone-shaped abutting surface 1111 can provide better support and friction, which helps to make the earphone 100 stably worn on the ear.

[0062] When worn, the earphone 100 of this embodiment can be supported on the user's cavum concha, cymba concha, and helix to achieve wearing of the acoustic device. The auricle 11 of the earphone 100 is fully or partially immersed in the groove formed by the cymba concha and cavum concha of the human ear, and the sound outlet 1111a is aligned with the user's ear canal opening, thereby increasing the resistance of the open earphone 100 to falling off the ear.

[0063] The ear shell 11 has a length direction and includes a first end and a second end located in the length direction. In the wearing state, the first end is closer to the helix of the human ear than the second end, and the second end is closer to the ear canal opening of the human ear than the first end. At the same time, the opening 11a is set at the first end or its adjacent position, providing the user with an intuitive and easy adjustment position. The ear hook 20 inserted into the guide groove 11b can slide along the extension direction of the guide groove 11b to fine-tune the position of the sound outlet 1111a to ensure that the sound outlet 1111a can be accurately aligned with the ear canal opening of the user. This sliding adjustment mechanism is not only easy to operate, but also can achieve fine adjustment to adapt to the ear size and shape of different users, thereby providing a personalized wearing experience.

[0064] In one embodiment, the connecting member 22 is arranged in an arc-shaped structure, and the shape of the guide groove 11b is adapted to the shape of the connecting member 22, that is, the connecting member 22 is allowed to slide smoothly in the guide groove 11b to achieve position adjustment. Figure 7During the wearing process, the contact point between the ear hook 20 and the upper part of the ear is defined as point O, and the distance from the ear canal opening to point O varies for different users. In this embodiment, on the one hand, the ear shell 11 is configured to have a length direction, and the connecting member 22 is connected to the first end along the length direction, and the connecting member 22 and the guide groove 11b are set to be arcs that match each other. In this way, it can be understood that during the adjustment process, the entire ear shell 11 is roughly swung with the part connected to the connecting member 22 as the center of the circle. Therefore, the ear shell 11 will be able to cause a larger position adjustment of the sound outlet 1111a adjacent to the second end at a smaller swing angle, so that a larger adjustment range can be obtained through a smaller movement amplitude.

[0065] Of course, in other embodiments, the connecting member 22 may also be in a straight line structure or a circular structure, and the shape of the guide groove 11b is still adapted to the connecting member 22. At this time, the movement of the ear shell 11 may also be linear motion, or it may also be swinging.

[0066] Please refer again Figure 8 The limiting structure 30 of the present application can provide a stop point after the user has adjusted the position of the sound outlet 1111a, so that after the user finds the best wearing position suitable for him / her, the earphone 100 can be firmly positioned without worrying about the accidental change of the position between the ear shell 11 and the ear hook 20, thereby ensuring the reliability of long-term wearing. That is, the first limiting portion 31 can move relative to the second limiting portion 32 and produce elastic abutment. Relying on the elastic characteristics of the first limiting portion 31, the connecting member 22 can be quickly slid and find a suitable wearing position. And the elastic abutment method can reduce the mechanical wear between the first limiting portion 31 and the connecting member 22 or the ear shell 11, thereby improving the durability and service life of the earphone 100.

[0067] like Figure 5 As shown, the first limiting portion 31 can be arranged on the ear shell 11, and the second limiting portion 32 can be arranged on the connecting member 22. It can be understood that the first limiting portion 31 can also be arranged on the connecting member 22, and the second limiting portion 32 can be arranged on the ear shell 11.

[0068] In one embodiment, the second position-limiting portion 32 is a wave-like structure, that is, the second position-limiting portion 32 includes a plurality of recesses and a plurality of protrusions arranged at intervals. The wave-like structure provides a plurality of recesses connected in sequence, which allows the first position-limiting portion 31 to have a plurality of fixed positions within a certain range, thereby increasing the continuity of the rotation of the first position-limiting portion 31. It can be understood that when the first position-limiting portion 31 stays at the protrusion position of the wave-like structure, a damping effect can be generated, so that the connecting member 22 is not easy to loosen after adjustment.

[0069] Specifically, the second limiting portion 32 includes at least two limiting grooves 32a. When the connecting member 22 slides along the guide groove 11b, part of the structure of the first limiting portion 31 can be moved to at least one of the two limiting grooves 32a in turn. Each limiting groove 32a serves as a fixed point to ensure the stability of the connecting member 22 when it is adjusted to a specific position, thereby preventing the connecting member 22 from sliding or shifting during use of the earphone 100. In this way, setting more than two limiting grooves 32a can meet the large range adjustment of the sound outlet 1111a, and after adjustment, it can be well positioned in the adjusted position, thus meeting the needs of different users.

[0070] It should be noted here that when the second limiting portion 32 is provided on the connecting member 22, the second limiting portion 32 may be an additional part on the connecting member 22, and the limiting groove 32a and the wavy structure are formed by parts other than the connecting member 22, or the limiting groove 32a is formed by the additional part and the connecting member 22 together. In other embodiments, the second limiting portion 32 may also be a concave-convex space structure formed by the connecting member 22 itself, and the present application does not impose any restrictions on this.

[0071] Exemplarily, there are three limit slots 32a, which are arranged in sequence. When the first limit portion 31 moves from one limit slot 32a to another adjacent limit slot 32a, the ear hook 20 can be rotated by a preset angle, such as 10 degrees or 20 degrees, relative to the sound-emitting component 10. The solution of the present application can also be specifically adjusted according to actual conditions, so that the sound-emitting port 1111a of the earphone 100 is aligned with the ear canal opening, so as to obtain the best sound reception experience.

[0072] like Fig.14 and Fig.15 As shown, in another embodiment, the second limiting portion 32 is a damping plate. The damping plate can be made of rubber material, or silicone or other elastic materials. The damping plate elastically abuts against the first limiting portion 31 and can move relatively. The damping plate can be fixed on the connecting member 22, and the damping plate can also be fixed on the ear shell 11. In this embodiment, when the user does not apply external force to the connecting member 22, the damping plate can provide a damping force to maintain the relative position of the connecting member 22 in the guide groove 11b, and then after the user adjusts the connecting member 22 according to the wearing requirements, the ear hook 20 and the ear shell 11 can maintain the relative position unchanged, thereby improving the user experience, and the damping plate can be provided so that the connecting member 22 can stay at various small adjustment angles to achieve stepless adjustment.

[0073] Please continue reading Fig.14 and Fig.15In any of the above embodiments, the first limiting portion 31 may be a spring sheet, and the spring sheet may be made of metal. The spring sheet made of metal has a simple structure, is not easy to be damaged, and has a relatively low manufacturing cost. The spring sheet includes an integrally formed spring sheet body 311a and a limiting protrusion 312a. The limiting protrusion 312a is connected to the spring sheet body 311a and is convexly arranged on one side of the spring sheet body 311a. The limiting protrusion 312a elastically abuts against the second limiting portion 32 and can move relatively. For example, the limiting protrusion 312a can be moved into at least two limiting grooves 32a in sequence, so as to realize the rotation of the ear hook 20. The design of the limiting protrusion 312a and the limiting groove 32a allows a certain degree of elastic adjustment. When the limiting protrusion 312a is squeezed by an external force, it can be deformed away from the direction of the external force; when the external force disappears, the limiting protrusion 312a is restored and abuts against the limiting groove 32a.

[0074] In one form, the groove wall of the guide groove 11b is provided with a first mounting groove 112b, and the end of the spring body 311a is provided with a bent portion 3111a, which is arranged in the first mounting groove 112b, providing a simple and stable mounting method to ensure that the spring remains in a fixed position during long-term use. The assembly process is simplified, and it is easy to quickly install and disassemble.

[0075] In other embodiments, Fig.16 and Fig.17 As shown, the first limiting portion 31 can also be a ball. The ball has a compact structure and will not significantly increase the volume of the earphone 100, which helps to maintain the lightness and portability of the earphone 100. The ball includes a sleeve 311b, a top abutment 312b and a spring arranged in the sleeve 311b. One end of the spring is connected to the sleeve 311b, and the other end is connected to the fixed decrement 312b, so that the top abutment 312b can be movably arranged in the sleeve 311b. The top abutment 312b elastically abuts against the second limiting portion 32 and can move relatively. For example, the top abutment 312b can be moved into at least two limiting grooves 32a in sequence, so as to realize the rotation of the ear hook 20. The sleeve 311b is arranged on the groove wall of the guide groove 11b. Specifically, the groove wall of the guide groove 11b is provided with a second mounting groove 112d. At least part of the sleeve 311b is fixedly arranged in the second mounting groove 112d, providing stable support to ensure the stability of the earphone 100 during wearing and use. The ball can be customized according to the specific design requirements of the limit groove 32a, providing design flexibility.

[0076] Exemplarily, the top stopper 312b may be one of a spherical top stopper, a cylindrical top stopper and a wedge-shaped top stopper. It can be understood that the specific structure of the top stopper 312b of the ball in the present application may also be other multiple structures.
