Description

[Technical Field]

[0001] The present application relates to the field of earphone technology, and more particularly to earphones. [Background technology]

[0002] Open-type earphones are earphones that do not completely seal the ear canal, allowing external sound to enter the ear while also transmitting sound in the form of sound waves to the vestibulocochlear nerve. This design allows open-type earphones to reduce the pressure on the ear canal when worn, so they do not cause discomfort even when worn for long periods of time and help keep the ear canal ventilated and dry, providing a more comfortable wearing experience. The open-type earphone design also helps prevent hearing fatigue and is more suitable for long-term use.

[0003] The ear hook structure and ear cup structure are key parts in the design of open-type earphones, and they jointly determine the stability and comfort of wearing the earphones. In related designs, when a user wears the ear part using the ear hook structure, the position of the acoustic opening of the ear cup structure is relatively fixed, so there may be situations where the ear part does not fit well to the external ear canal, thereby reducing the hearing effect. Summary of the Invention [Means for solving the problem]

[0004] The earphones provided in the embodiments of the present application can adjust the position of the sound opening so that the sound opening fits better into the ear canal, thereby improving the hearing effect.

[0005] The earphone provided in the present embodiment includes an acoustic member, an ear hook, and a position limiting structure.

[0006] The acoustic member includes ear cups, and the ear cups are provided with openings and guide grooves that communicate with the openings; the ear hooks include an ear hook body and a connecting member that are connected to each other, and the ear hook body passes through the opening and the connecting member is located within the guide groove and is able to slide along the guide groove; the position limiting structure includes a first position limiting part and a second position limiting part, and the first position limiting part is provided on one of the connecting member or the ear cup and the second position limiting part is provided on the other of the connecting member or the ear cup, and the first position limiting part elastically abuts against the second position limiting part and is able to move relative to it.

[0007] The earphones according to the embodiments of the present application have a connecting member that slides into the guide groove, allowing the user to adjust the position of the acoustic opening of the ear cup by sliding between the ear cup and the connecting member of the ear hook according to the shape and size of the individual auricle, thereby adjusting the acoustic opening of the ear cup to a position that is as aligned as possible with the user's outer ear canal, improving the acoustic performance of the earphones and enhancing the user's hearing experience.

[0008] This embodiment of the present application further comprises a first position limiting portion and a second position limiting portion, the first position limiting portion can be attached to the ear cup or the connecting member, and is capable of moving relative to the second position limiting portion and elastically abutting against it; in other words, after being adjusted to an appropriate position, the position between the ear cup and the connecting member can be fixed relatively by fitting the first position limiting portion into the second position limiting portion, so the position of the acoustic component can be stably maintained in an optimal position, there is no need to worry about the position between the ear cup and ear hook changing unexpectedly, and reliability for long-term wearing is ensured.

[0009] Furthermore, in the technical solution of the present application, a guide groove is formed inside the ear cup, and the connector of the ear hook extends from the opening into the guide groove to achieve a sliding connection. The structural form of this adjustment structure is simple and makes full use of the internal space of the ear cup, making the overall volume of the earphone compact and lighter, which is more convenient for users to wear for long periods of time.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The realization of the object, the functional features and advantages of the present invention will be further explained on the basis of examples and with reference to the accompanying drawings.

[0013] To make the objectives, technical solutions and advantages of the present application clearer, the following provides a more detailed description of the embodiments of the present application with reference to the accompanying drawings.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing specific examples only and are not intended to limit the scope of this application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0017] An earphone is an audio frequency reproduction device, mainly used for personal listening needs. It consists of a pair of transducer units that can receive electrical signals from a media player or receiver and convert them into audible sound waves by a speaker placed close to the ear.

[0018] With the continuous development of earphone technology, users have increasingly higher requirements for earphone comfort and acoustic performance. Open-type earphones do not block the ear canal, reducing the sense of pressure on the ear canal and preventing discomfort even when worn for extended periods of time. They also help maintain ventilation and dryness in the ear canal. This design also allows users to hear some external sounds, such as ambient noise and other people's conversations, while enjoying music. This design not only improves wearing comfort, but also eliminates the sense of pressure on the ears, preventing discomfort even when worn for extended periods of time. Furthermore, the design maintains connectivity with the outside world, facilitating communication. Therefore, these earphones are increasingly accepted by consumers.

[0019] The open-type earphone structure includes a type that is attached to the ear by an ear hook. This type of earphone structure includes an ear hook and an acoustic structure connected to the ear hook. In a typical design, the ear hook and the ear cup of the acoustic structure are fixedly connected. With this type of structure, the relative positions of the acoustic opening of the ear cup and the external ear canal cannot be adjusted during the wearing process, so sound cannot be accurately transmitted into the ear, which may affect acoustic performance and result in poor hearing effect.

[0020] In the related art, open-type earphones are designed with a relatively complicated gear structure or hinge connection structure between the ear hook and the ear cup to allow the position of the acoustic port to be adjusted. However, this installation method requires a relatively large structure to be designed in the ear cup to accommodate and attach parts such as gears and hinges, which makes the overall earphone structure relatively large and increases the weight of the earphone, which may cause discomfort to the user's ears when worn for long periods of time.

[0021] 1 and 2, the present application proposes an earphone 100, which is an open-type earphone and is of an air-conduction type. The earphone 100 includes an acoustic member 10 and an ear hook 20 connected to the acoustic member 10, and the ear hook 20 has a curved structure.

[0022] 3 to 5, the acoustic member 10 includes ear cups 11 and a speaker unit 12. The ear cups 11 can be made of plastic, metal, silicone, or other materials. Furthermore, the relatively flat structure allows the acoustic member 10 to fit more closely to the ear after the earphone 100 is worn, improving stability and comfort after wearing. A receiving cavity 11c is formed within the ear cups 11, and the speaker unit 12 is received within the receiving cavity 11c. The ear cups 11 are also provided with an acoustic opening 1111a. The acoustic opening 1111a is an important component of the acoustic member of the earphone and is responsible for outputting sound waves generated by the acoustic unit inside the earphone to the user's outer ear canal in a specific direction. Therefore, in this embodiment, the acoustic opening 1111a is positioned to at least partially cover the user's outer ear canal. The speaker unit 12 propagates generated sound outward through the acoustic opening 1111a during operation.

[0023] The ends of the ear hooks 20 are connected to the ear cups 11, and the entire ear hook 20 has a certain shape-changing ability, and its overall shape fits the shape of the back of the earpinna. In some embodiments, it comprises a plastic rod-shaped body, and a shape-memory metal wire can be embedded in the rod-shaped body. This structural form allows the ear hooks 20 to have relatively good toughness and bending ability, making it easier to pull during the wearing process and also advantageous for its own restoration.

[0024] The earphone 100 of the present application has a battery 42 capable of supplying power to the speaker unit 12. There are no restrictions on the specific type of battery; for example, a rechargeable lithium battery can be used, which makes the earphone 100 convenient to use and carry.

[0025] In one structural form, the battery can be accommodated in the accommodation cavity 11c. When installed in this manner, the entire earphone 100 is divided into two parts, which can also be called a two-stage design. As can be seen, in a two-stage design, the tangent line between the battery and the speaker unit 12 is relatively short, and the wiring is relatively simple. Naturally, in this case, most of the overall mass of the earphone 100 is concentrated on the acoustic member 10. In this case, to further stabilize the entire wearing process of the earphone 100, the length of the ear hook 20 can be correspondingly extended, for example, one end of the ear hook 20 away from the acoustic member 10 can be extended to a position corresponding to the earlobe. This allows the ear hook 20 to have a relatively large contact area with the ear, thereby realizing a stable wearing of the earphone 10.

[0026] 6 and 7, in yet another structure, the earphone 100, apart from both the acoustic member 10 and the ear hook 20, further includes a battery case 40, and as shown in FIGS. 16 and 17, the battery case 40 includes a cover 41 and a battery 42 housed within the cover 41. In other words, in this embodiment, the earphone 100 is provided with three parts, the acoustic member 10, the ear hook 20, and the battery case 40, and is configured as a three-tiered structure. The battery case 40 is connected to the other end of the ear hook 20, i.e., the end remote from the acoustic member 10. 7 shows the earphone 100 being worn outside the user's ear during actual use, and as can be seen from the figure, during the wearing process, the ear hook 20 is attached to the back of the pinna of the ear, the acoustic member 10 extends from the crus of the helix to the cavity of the concha, and the acoustic opening 1111a is positioned to fit into the external ear canal, so that sound emitted by the speaker unit 12 propagates in a fixed direction through the acoustic opening 1111a to the external ear canal. The battery case 40 is located on the back of the pinna and corresponds to the position of the earlobe of the ear.

[0027] The three-stage structural design helps distribute the weight of the earphone 100 more evenly, increasing comfort during wearing, and the independent battery case 40 makes maintenance easier. Naturally, the independent battery case 40 can also provide more space for the battery 42, making it easier to design the battery 42 with a larger capacity, and correspondingly enhancing the operating durability of the earphone 100.

[0028] Furthermore, in any of the above embodiments, in order to make it possible to adjust the position of the sound port 1111a, the ear cup 11 is provided with an opening 11a and a guide groove 11b that communicates with the opening 11a, the ear hook 20 includes an ear hook main body 21 and a connecting member 22 that are connected to each other, the ear hook main body 21 passes through the opening 11a, and the connecting member 22 is located within the guide groove 11b and is able to slide along the guide groove 11b, and the earphone 100 further includes a position limiting structure 30, the position limiting structure 30 including a first position limiting portion 31 and a second position limiting portion 32, the first position limiting portion 31 being provided on one of the connecting member 22 and the ear cup 11, and the second position limiting portion 32 being provided on the other of the connecting member 22 and the ear cup 11, the first position limiting portion 31 elastically abutting against the second position limiting portion 32 and being able to move relative to it.

[0029] In other words, the earphone 100 of the present application has a connecting member 22 that slides and connects within the guide groove, allowing the user to adjust the position of the acoustic opening 1111a of the earcup 11 by sliding between the earcup 11 and the connecting member 22 of the earhook 20 according to the shape and size of the individual auricle, thereby allowing the acoustic opening 1111a of the earcup 11 to be adjusted to a position that matches the user's outer ear canal as much as possible, improving the acoustic performance of the earphone 100 and enhancing the user's hearing experience.

[0030] 8, 9 and 10, the ear cup 11 includes a housing 111 and a partition plate 112 installed in the housing 111, the partition plate 112 and a part of the inner wall of the housing 111 define a guide groove 11b, the partition plate 112 and another part of the inner wall of the housing 111 define an accommodating cavity 11c, and the above-mentioned opening 11a is formed in the housing 111.

[0031] For ease of assembly, in a series of structural forms, the housing 111 includes a first housing 1113 and a second housing 1114 that are engaged and connected to each other, and the engaging (snap-fit) design provides greater design flexibility, so that the shapes and dimensions of the first housing 1113 and the second housing 1114 can be adjusted according to different functional requirements, and installation, removal, and maintenance are relatively convenient.

[0032] In order to improve waterproofing, a ring-shaped waterproof groove 11131 is provided around the periphery of the first housing 1113, and a ring-shaped waterproof boss 11141 that fits into the ring-shaped waterproof groove 11131 is provided around the periphery of the second housing 1114. After the first housing 1113 and the second housing 1114 are mated together, the ring-shaped waterproof boss 11141 fits into the ring-shaped waterproof groove 11131, effectively preventing external liquid from seeping into the receiving cavity 11c. This better protects the internal components of the ear cups 11, reduces damage caused by water intrusion, and extends the service life of the earphones 100. Naturally, the mating of the ring-shaped waterproof boss 11141 and the ring-shaped waterproof groove 11131 allows the entire ear cups 11 to be sealed at the seams, which also conceals the seams and improves the aesthetics of the ear cups 11.

[0033] As can be understood here, in order to further strengthen the tightness of the connection between the first housing 1113 and the second housing 1114 and improve the waterproof and sweatproof function of the ear cups 11, the first housing 1113 and the second housing 1114 can also be fixedly connected by ultrasonic welding or adhesive, and as long as the connection effect can be achieved, the connection method between the first housing 1113 and the second housing 1114 can also be other, and this application does not limit it.

[0034] Referring to Figure 11, the partition plate 112 can include two parts installed halfway, and both parts of the partition plate 112 are connected to the inner walls of the first housing 1113 and the second housing 1114, respectively. After the first housing 1113 and the second housing 1114 are engaged, both parts of the partition plate 112 are combined and connected. Naturally, the partition plate 112 can also be made into one and connected to the inner wall of one of the first housing 1113 and the second housing 1114. After the first housing 1113 and the second housing 1114 are engaged, the partition plate 112 and the other of the first housing 1113 and the second housing 1114 are sealed and abutted against each other, so that the partition plate 112 can fit into part of the inner wall surfaces of the first housing 1113 and the second housing 1114 to define the above-mentioned guide groove 11b.

[0035] In the three-stage earphone 100, as shown in Figs. 11, 12 and 13, the earphone 100 further includes a conductor 50 and a sealing ring 60 fitted around the conductor 50. Since the speaker unit 12 in the receiving cavity 11c and the battery 42 in the battery case 40 must be connected via the conductor 50, a wire outlet hole 22a for the conductor 50 to pass through is opened in the connecting member 22, and a wiring hole 112a can be opened in the partition plate 112 at a position opposite to the wire outlet hole 22a. The wiring hole 112a connects the receiving cavity 11c and the guide groove 11b. The wiring hole 112a is used to guide the conductive wire 50 from the receiving cavity 11c through the guide groove 11b, and then through the wire outlet hole 22a into the ear hook main body 21, and finally into the battery case 40. This type of wiring format can prevent the tangents inside the earphone 100 from being bent too many times and becoming disorderly, and the connection between the wiring parts and the speaker unit 12 is connected via the conductive wire 50 and distributed within the ear hook main body 21, and is effectively coupled, making the structure more compact.

[0036] In order to prevent the speaker unit 12 in the receiving cavity 11c from being corroded by moisture and sweat, a sealing ring 60 is fitted onto the end of the lead wire 50 that is away from the battery case 40, and the sealing ring 60 is fitted into the wiring hole 112a to reduce the occurrence of assembly gaps. The connection between the sealing ring 60 and the wiring hole 112a can further provide cushioning and support for the lead wire 50, preventing the lead wire 50 from being easily scratched at the wiring hole 112a, ensuring the safety of the internal circuit of the earphone 100 and preventing potential short circuits and damage.

[0037] Furthermore, an annular groove 60a is formed on the outer wall of the sealing ring 60, and an annular protrusion that fits into the annular groove 60a is provided on the inner wall of the wiring hole 112a, so that the sealing ring 60 and the wiring hole 112a form a tighter sealing connection, effectively preventing moisture, dust and other external substances from entering the earphone 100. The strengthened sealing connection helps improve the waterproof and sweatproof rating of the earphone 100, making it more suitable for use in excessively hydrated or humid environments.

[0038] For example, the sealing ring 60 may be a plastic watertight (SR) sealing ring 60, which can provide good sealing performance under different operating environments, can effectively prevent external fluids from entering regardless of whether the application is static or dynamic, and has relatively strong corrosion resistance, so it is not easily damaged or deteriorated, and can extend the service life of the earphone 100.

[0039] The ear hook body 21 has a rod-shaped structure and includes a rod-shaped body made of plastic material, with a shape-memory metal wire installed within the rod-shaped body of the ear hook body 21, and the connecting member 22 is made to match the material of the rod-shaped body of the ear hook body 21 and can be manufactured by a one-piece injection molding method. In a three-stage structure, the cover 41 of the battery case 40 is connected to the end of the ear hook body 21 that is away from the ear cup 11. The rod-shaped body of the ear hook body 21 can be made of a soft thermoplastic polyurethane (TPU) plastic material, which makes it more comfortable for the user to wear and does not cause ear pain even when worn for long periods of time, and the connecting member 22 can be made of a hard acrylonitrile-butadiene-styrene (ABS) plastic material, which has relatively high structural strength and allows for smoother rotation. The ear hook body 21 and the connecting member 22 are integrated using secondary injection molding, which increases the durability of the connection between them. Of course, in other structural forms, when the connecting material 22 and the ear hook body 21 are of a separate structural form, the connecting material 22 may be further fixed together by adhesive, welding, etc., or by other connection methods such as screw connection, locking connection, etc., and this application does not limit this.

[0040] Furthermore, the guide groove 11b of the present application extends along the circumferential direction of the ear cup 11, with first and second position limiting surfaces respectively provided at both ends of the guide groove 11b, the connecting member 22 sliding between the first and second position limiting surfaces, and the first and second position limiting surfaces at least partially providing a clear adjustment range for the sliding of the ear hook 20, ensuring that the user does not exceed the effective limit when adjusting the earphone 100. In this embodiment, the opening length of the opening 11a must be smaller than the distance between the first and second position limiting surfaces, and the length dimension of the connecting member 22 must be greater than the opening length dimension of the opening 11a, which design further prevents the connecting member 22 from slipping out of the guide groove 11b. As can be understood, the above design in which the length dimension of the connecting material 22 is greater than the opening length dimension of the opening 11a is only one possible way to prevent the connecting material 22 from slipping out of the opening 11a. In other designs, if the connecting material 22 can be positioned on the first position limiting surface and the second position limiting surface, methods such as making the width dimension of the connecting material 22 greater than the width dimension of the opening 11a or adding other position limiting structures can also be used.

[0041] To further explain the positional relationship between the acoustic port 1111a and the opening 11a in the ear cup 11, the outer surface of the housing 111 can be divided into a contact surface 1111 and a side surface 1112 (see Figure 6) depending on the contact state with the ear part when the earphone 100 is worn, the contact surface 1111 is the surface that comes into contact with the ear part when worn, the side surface 1112 is the periphery that connects to the contact surface 1111, the side surface 1112 is a surface that does not come into contact with the ear part when the earphone 100 is worn, and if the ear cup 11 is designed with a flat structure, the side surface 1112 can also be recognized as a surface that extends in the thickness direction of the ear cup 11. 9 and 10, the acoustic opening 1111a is located on the first housing 1113, the abutment surface 1111 is the surface on which the acoustic opening 1111a of the first housing 1113 is located, and the side surface 1112 is jointly defined by the first housing 1113 and the second housing 1114. The acoustic opening 1111a is opened on the abutment surface 1111, and by having the acoustic opening 1111a located on the abutment surface 1111, it is possible to ensure that sound is transmitted directly to the user's ear canal when the earphones 100 are worn, reducing loss during the sound transmission process. Because the opening 11a is opened on the side surface 1112, the user can more easily manipulate the ear hook 20 exposed outside the opening 11a and slide the connecting member 22 in the guide groove 11b accordingly, and the connection position between the ear hook 20 and the ear cup 11 does not easily interfere with the user's ear skin during the adjustment process.

[0042] Furthermore, at least a portion of the contact surface 1111 has a truncated cone-shaped structure, and the truncated cone-shaped structure defines an acoustic opening 1111a, which allows the acoustic opening 1111a to fit more closely to the ear canal, thereby forming a certain degree of sealing and positioning effect and enhancing low-frequency response. The truncated cone-shaped contact surface 1111 can provide better support and friction, helping the earphone 100 to be worn more stably on the ear.

[0043] When worn, the earphone 100 of this embodiment is supported by the user's concha, the fin, and the helix, allowing the acoustic device to be worn. The earcups 11 of the earphone 100 are fully or partially immersed in the grooves formed by the concha and the concha, and the acoustic opening 1111a is aligned with the user's external ear canal, thereby increasing the resistance to the open-type earphone 100 falling out of the ear.

[0044] The earcups 11 have a longitudinal direction and include a first end and a second end positioned in the longitudinal direction. When worn, the first end is closer to the helical crus of the ear than the second end, and the second end is closer to the ear canal than the first end. At the same time, the opening 11a is located at or adjacent to the first end, providing the user with an intuitive and easy adjustment position. The earhooks 20 extending into the guide grooves 11b slide along the extension direction of the guide grooves 11b, allowing for fine adjustment of the position of the acoustic opening 1111a and ensuring that the acoustic opening 1111a can be accurately aligned with the user's ear canal. This sliding adjustment mechanism is not only easy to operate, but also allows for fine adjustment to accommodate different users' ear sizes and shapes, providing a personalized wearing experience.

[0045] In one embodiment, the connecting member 22 is installed with an arc-shaped structure, and the shape of the guide groove 11b matches the shape of the connecting member 22, allowing the connecting member 22 to slide stably within the guide groove 11b, thereby achieving position adjustment. Referring further to Figure 7, during the wearing process, the contact point between the ear hook 20 and the upper part of the ear is defined as point O. However, since the distance from the external ear canal to point O varies depending on the user, in this embodiment, on the one hand, the ear cups 11 are arranged with a longitudinal direction, and the connecting member 22 is connected to a first end along the longitudinal direction, and the connecting member 22 and the guide groove 11b are installed so as to form an interlocking arc shape. Therefore, during the adjustment process, the entire ear cup 11 swings approximately around the part where it connects to the connecting member 22, so that a relatively small swing angle of the ear cup 11 causes a relatively large position adjustment of the sound port 1111a near the second end, and it can be understood that a relatively small movement width can achieve a relatively large adjustment range.

[0046] Of course, in other embodiments, the connecting member 22 can have a rectangular or circular structure, and the shape of the guide groove 11b can also be adapted to the connecting member 22, in which case the movement of the ear cup 11 can be linear or swinging.

[0047] 8 , the position limiting structure 30 of the present application can provide a stopping point for the user after completing the position adjustment of the sound port 1111a. After the user finds the optimal wearing position, the earphone 100 can be stably positioned and there is no need to worry about unexpected changes in the position between the ear cup 11 and the ear hook 20, ensuring reliable wearing over a long period of time. That is, the first position limiting portion 31 can move relative to the second position limiting portion 32 to form an elastic contact. The elastic properties of the first position limiting portion 31 allow the connecting member 22 to slide quickly and find the optimal wearing position. Furthermore, the elastic contact method reduces mechanical wear between the first position limiting portion 31 and the connecting member 22 or the ear cup 11, thereby improving the durability and service life of the earphone 100.

[0048] 5, the first position limiting portion 31 can be installed on the ear cup 11, and the second position limiting portion 32 can be installed on the connecting material 22. As can be understood, the first position limiting portion 31 can also be installed on the connecting material 22, and the second position limiting portion 32 can also be installed on the ear cup 11.

[0049] In one embodiment, the second position limiting portion 32 has a wave-like structure, i.e., the second position limiting portion 32 includes a plurality of recesses and a plurality of protrusions spaced apart from each other. The wave-like structure provides a plurality of recesses connected in series, thereby allowing the first position limiting portion 31 to have a plurality of fixed positions within a certain range and increasing the continuity of rotation of the first position limiting portion 31. As can be seen, when the first position limiting portion 31 remains at the protrusion position of the wave-like structure, a damping effect can be generated, and the first position limiting portion 32 will not easily loosen after adjusting the connecting member 22.

[0050] Specifically, the second position limiting portion 32 includes at least two position limiting grooves 32a, and when the connecting member 22 slides along the guide groove 11b, a portion of the structure of the first position limiting portion 31 can sequentially move to one of the at least two position limiting grooves 32a, with each position limiting groove 32a as a fixed point to ensure stability when adjusting the connecting member 22 to a specific position and prevent the connecting member 22 from sliding or displacing during use of the earphone 100. Therefore, by installing two or more position limiting grooves 32a in this manner, when a wide range of adjustment of the acoustic port 1111a can be satisfied, each can be positioned very well after adjustment, thereby adapting to the needs of different users.

[0051] It should be explained here that when the second position limiting portion 32 is installed on the connecting material 22, the second position limiting portion 32 can be an extraneous component of the connecting material 22, and the position limiting groove 32a and the wave-like structure can be formed by a component other than the connecting material 22, or the extraneous component and the connecting material 22 can be fitted together to form the position limiting groove 32a. However, in other embodiments, the second position limiting portion 32 can also be an uneven spatial structure formed by the connecting material 22 itself, and this application does not restrict this.

[0052] For example, three position limiting grooves 32a are provided, and the three position limiting grooves 32a are sequentially distributed, so that when the first position limiting part 31 moves from one of the position limiting grooves 32a to the adjacent other position limiting groove 32a, the ear hook 20 can be rotated by a predetermined angle, for example, 10 degrees or 20 degrees, relative to the acoustic member 10. The technical solution of the present application can also be specifically adjusted according to actual situations to align the acoustic opening 1111a of the earphone 100 with the ear canal to achieve an optimal listening experience.

[0053] 14 and 15, in yet another embodiment, the second position limiting portion 32 is a damping piece. The damping piece can be made of rubber, or silicone or other elastic materials. The damping piece elastically abuts against the first position limiting portion 31 and is relatively movable. The damping piece can be fixed to the connecting piece 22, or the damping piece can be fixed to the ear cup 11. In this embodiment, when the user does not apply external force to the connecting piece 22, the damping piece can provide a damping force to hold the connecting piece 22 in its relative position within the guide groove 11b. After the user adjusts the connecting piece 22 according to wearing needs, the relative positions of the ear hook 20 and the ear cup 11 will remain unchanged, improving the user experience. The installation form of the damping piece allows the connecting piece 22 to remain at each minute adjustment angle, achieving stepless adjustment.

[0054] 14 and 15, in any of the above embodiments, the first position limiting portion 31 can be an elastic piece, which can be made of metal. Metal elastic pieces have a simple structure, are not easily damaged, and are relatively inexpensive to manufacture. The elastic piece includes an integrally molded elastic piece main body 311a and a position limiting protrusion 312a. The position limiting protrusion 312a is connected to the elastic piece main body 311a and is protruded from one side of the elastic piece main body 311a. The position limiting protrusion 312a elastically abuts against the second position limiting portion 32 and is movable relative to it. For example, the position limiting protrusion 312a can move sequentially into at least two position limiting grooves 32a to rotate the ear hook 20. The design of the position limiting protrusion 312a and the position limiting groove 32a allows for a certain degree of elastic adjustment, so that when the position limiting protrusion 312a is pressed by an external force, it can deform in a direction away from the external force, and when the external force disappears, the position limiting protrusion 312a returns to its original position and abuts against the position limiting groove 32a.

[0055] In one embodiment, a first mounting groove 112b is formed in the groove wall of the guide groove 11b, and a bent portion 3111a is provided at the end of the elastic piece body 311a, which is installed in the first mounting groove 112b, providing a simple and firm mounting method that ensures the elastic piece stays in place for long periods of use, simplifies the assembly process, and facilitates quick installation and removal.

[0056] 16 and 17, the first position limiting portion 31 can be a wave bead, which has a compact structure and does not significantly increase the volume of the earphone 100, thereby helping to maintain the light weight and portability of the earphone 100. The wave bead includes a sleeve 311b, a retainer 312b and a spring installed in the sleeve 311b, one end of the spring is connected to the sleeve 311b and the other end is connected to the retainer 312b, so that the retainer 312b is movably installed within the sleeve 311b. The retainer 312b elastically abuts against the second position limiting portion 32 and is movable relative to it. For example, the retainer 312b can move sequentially into at least two position limiting grooves 32a to rotate the earhook 20. The sleeve 311b is installed on the groove wall of the guide groove 11b, specifically, a second mounting groove 112d is opened on the groove wall of the guide groove 11b, and at least a portion of the sleeve 311b is fixedly installed in the second mounting groove 112d to provide stable support and ensure stability during wearing and use of the earphone 100. The wave bead can be customized according to the specific design requirements of the position limiting groove 32a, providing design flexibility.

[0057] Illustratively, the retainer 312b may be one of a spherical retainer, a columnar retainer, and a wedge-shaped retainer, and as can be understood herein, other types of structures may also be used in conjunction with the specific structure of the wave bead retainer 312b.
