[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Open-back headphones are a type of headphone design that doesn't go into the ear, allowing external sound to enter and enabling users to better perceive their surroundings, thus avoiding some potential safety risks. Based on the connection method, open-back headphones can be divided into two types: true wireless headphones and neckband headphones. Neckband headphones consist of a neckband cable and earpieces at both ends of the cable. When not in use, neckband headphones can be hung around the neck, avoiding frequent removal by the user, and are therefore widely used in sports, outdoor activities, and other scenarios. The inventors discovered that in current neckband headphones, the neckband cable is usually fixedly connected to the earpiece, which is not only inconvenient for storage, but also makes the cable length difficult to adjust, failing to meet the needs of different users and affecting the user experience.

[0027] Please see Figures 1-2This application provides a neckband assembly 10, which includes two connection terminals 11 and a neckband cable 12. One end of the neckband cable 12 is connected to one connection terminal 11, and the other end of the neckband cable 12 is connected to the other connection terminal 11. The connection terminals 11 can be connected to headphones 20. Thus, the neckband assembly 10 and headphones 20 can be interconnected to form a headphone assembly 1 with neckband function. The neckband cable 12 is a one-piece molded structure, which is not only structurally stable and reliable, but also does not have additional electronic components (such as power interface, buttons, earpiece, etc.), which helps to reduce the pressure of the neckband cable on the user's head when wearing it, reduces the wearing burden of the neckband assembly, and ensures the user's comfort during long-term use.

[0028] The retractable neck strap 12 has an adjustable length within a certain range, allowing it to be adjusted according to the user's head size, thus making the neck strap component suitable for different people. Since everyone's head size is different, traditional fixed neck straps cannot fit all users. However, the retractable neck strap 12 in this embodiment can better adapt to different users' head sizes, providing a more comfortable wearing experience. In this application, the retractability of the neck strap 12 refers to the adjustable relative distance between its two ends. This adjustment can be achieved in various ways, and the structure of the neck strap 12 in this embodiment is described below.

[0029] In some embodiments, the neck strap 12 is a spring-loaded cord. As a retractable cord, the length of the spring-loaded cord can be freely adjusted according to actual needs to meet the requirements of different users and usage scenarios. In actual use, when the length of the neck strap 12 needs to be extended, simply pull the neck strap 12; when the length of the neck strap 12 needs to be shortened, simply loosen the neck strap 12. This allows for convenient adjustment of the length of the neck strap assembly 10. The spring-loaded cord not only meets the needs of stretching and retraction but also adapts to various bending and folding states. Thus, the spring-loaded cord can be folded by winding or bending to reduce the space occupied by the neck strap 12, making it convenient for users to carry and store.

[0030] Alternatively, the neckband 12 can also be made of an elastic material. This material has tensile and resilience properties, allowing users to stretch the neckband 12 to a suitable length according to their head shape and wearing preferences. The elastic material's resilience helps maintain this length, and the wearing position can be adjusted by re-stretching the neckband 12. After removing the headphones, the neckband 12 relaxes and returns to its original length, making it convenient and practical.

[0031] In some embodiments, the neckband 12 is at least partially spiral-shaped to allow for telescopic adjustment. Specifically, the neckband 12 includes a first connecting wire 121 and two second connecting wires 122, each connected to one end of the first connecting wire 121. The first connecting wire 121 is spiral-shaped, allowing for length adjustment of the neckband 12 by pulling or releasing it, thus adapting to different users. The spiral shape ensures even stress distribution during stretching and contraction, reducing the risk of damage due to overstretching or twisting. Furthermore, the second connecting wires 122 can be straight, curved, or a combination of straight and curved shapes, better accommodating the user's head curve and improving wearing comfort.

[0032] For example, the material of the neck brace 12 includes at least one of silicone, thermoplastic polyurethane elastomer rubber, and thermoplastic polyester elastomer. It is understood that silicone is a non-static silica with excellent high-temperature resistance, low-temperature resistance, and weather resistance, facilitating the use of the neck brace 12 under various working conditions. Thermoplastic polyurethane elastomer rubber (TPU) is a linear thermoplastic elastomer copolymer. TPU has high flexibility and durability, as well as high mechanical strength, giving the neck brace 12 of this application a long service life and superior shape retention. Thermoplastic polyester elastomer (TPEE) is an engineering-grade elastomer with advantages such as high mechanical strength, good elasticity, creep resistance, and high flexural fatigue resistance, giving the neck brace 12 of this application a long service life.

[0033] It should be noted that regardless of the material used to make the neckline 12, as long as the extensibility of the molded neckline 12 meets the usage requirements, it is acceptable. In specific implementations, the neckline 12 can be processed using various methods, including but not limited to injection molding, extrusion, blow molding, and meltblowing.

[0034] Please see Figures 2-3 This application also provides an earphone assembly 1, which includes a neckband assembly 10 and earphones 20. The connecting terminal 11 of the neckband assembly 10 is detachably connected to the earphones 20. Thus, the earphones 20 can be used independently or connected to the neckband assembly 10 to form an earphone assembly 1 with neckband function. The detachable connection between the neckband assembly 10 and the earphones 20 allows the earphone assembly 1 to be used in different scenarios, thereby improving its performance.

[0035] It is understood that the earphone 20 of the headphone assembly 1 can be a separate earphone, including but not limited to clip-on and ear-hook earphones. The earphone 20 can be used independently, is compact, and easy to carry and store. The earphone 20 can also be connected to the neckband assembly 10 so that the user can wear the headphone assembly 1 around their neck, suitable for scenarios where it is worn for a long time or where the earphone needs to be frequently removed. The headphone assembly 1 of this application not only provides users with a more flexible and convenient way of use, but also facilitates independent repair of the neckband assembly 10 and the earphone 20. When one component fails, the repair personnel can more quickly locate the faulty component during fault diagnosis, and the user does not need to replace the entire headphone assembly, but only needs to repair and replace the faulty component, which helps to reduce repair costs.

[0036] Please see Figure 4 The earphone 20 includes an earphone body 21 and a connector 22 connected to each other. The connector 22 is used for detachable connection to the connector terminal 11. The content of this application will be further elaborated below based on the detachable connection of the connector 22 and the connector terminal 11.

[0037] In some embodiments, the connecting terminal 11 is plugged into the earphone 20. In specific implementations, the connecting base 22 is provided with a plug-in interface 220, which can be configured as the charging interface of the earphone 20 to simplify the structure of the earphone 20; alternatively, the plug-in interface 220 and the charging interface of the earphone 20 can be spaced apart to avoid damage to the charging interface caused by frequent disassembly and reassembly of the neckband assembly 10.

[0038] The connecting terminal 11 has a slot 110, and a plug-in portion 111 is provided in the slot 110. The plug-in portion 111 is plugged into the plug-in interface 220, and the connecting seat 22 is at least partially inserted into the slot 110. The cooperation between the slot 110 and the connecting seat 22 ensures stable contact between the plug-in portion 111 and the plug-in interface 220, preventing the connection point from being exposed to the outside. When the connecting terminal 11 and the connecting seat 22 are subjected to external vibration, impact, or other forces, the connection structure of the slot 110 and the connecting seat 22 bears a portion of the force, preventing stress concentration on the plug-in portion 111 and the plug-in interface 220, thereby effectively reducing the probability of damage to the plug-in portion 111 due to external factors.

[0039] The connector 22 has a first end face away from the headphone body 21, and the plug-in interface 220 is located on the first end face. Along the extension direction of the connector 22, the cross-sectional area of ​​the connector 22 gradually decreases from the headphone body 21 toward the first end face, so that the outer surface of the connector 22 forms a guide curved surface. When the neckband assembly 10 is installed on the headphone 20, the first end face first contacts the entrance edge of the slot 110. Under the guidance of its outer surface, the connector 22 is inserted into the slot 110. During this process, the plug-in part 111 and the plug-in interface 220 gradually approach and align until they are successfully connected.

[0040] In some embodiments, the connecting terminal 11 and the earphone 20 are magnetically engaged. This magnetic engagement ensures the connection stability between the earphone 20 and the neckband assembly 10, and results in relatively low wear on the connecting terminal 11 and the earphone 20, thus maintaining long-term stability and reliability.

[0041] Optionally, one of the connecting terminal 11 and the connecting base 22 may be made of magnetic metal, while the other may have a magnetic element. The magnetic force of the magnetic metal and the magnetic element allows the earphone 20 and the neckband assembly 10 to magnetically engage. For example, the connecting base 22 may be made of a magnetic metal, such as iron, nickel, or cobalt, while the connecting terminal 11 may have a magnetic element, such as a magnet. In this way, when the earphone 20 approaches the connecting terminal 11, the connecting base 22 and the connecting terminal 11 will attract each other due to the magnetic force, thus achieving a stable connection. Conversely, the connecting terminal 11 may also be made of magnetic metal, while the connecting base 22 may have a magnetic element. In this way, when the earphone 20 approaches the connecting terminal 11, the connecting base 22 and the connecting terminal 11 will attract each other due to the magnetic force, also achieving a stable connection.

[0042] Optionally, please refer to Figure 5 Both the connecting terminal 11 and the connecting base 22 are equipped with magnetic elements. The magnetic force between the two magnetic elements enables the earphone 20 and the neckband assembly 10 to magnetically engage. Specifically, the connecting base 22 has a first mounting cavity, in which a first magnetic element 221 is disposed. The connecting terminal 11 has a second mounting cavity, in which a second magnetic element 112 is disposed. Thus, the first magnetic element 221 and the second magnetic element 112 magnetically engage. By rationally designing the position and strength of the first magnetic element 221 and the second magnetic element 112, the magnetic force distribution can be balanced, reducing connection instability caused by uneven magnetic force.

[0043] In some embodiments, the connecting terminal 11 is snapped into the connecting seat 22. One of the connecting terminal 11 and the connecting seat 22 is provided with a snap-in protrusion and the other is provided with a snap-in groove. The snap-in protrusion is snapped into the snap-in groove, thereby achieving a stable connection.

[0044] Optionally, the connecting terminal 11 may be provided with a snap-fit ​​protrusion, and the connecting seat 22 may be provided with a snap-fit ​​groove; or the connecting terminal 11 may be provided with a snap-fit ​​groove, and the connecting seat 22 may be provided with a snap-fit ​​protrusion; or the connecting terminal 11 may be provided with both a snap-fit ​​protrusion and a snap-fit ​​groove, and the connecting seat 22 may be provided with both a corresponding snap-fit ​​groove and a snap-fit ​​protrusion. No specific limitations are made in the embodiments of this application.

[0045] The snap-fit ​​protrusion can be a tongue-shaped structure or a hook-shaped structure, etc. In addition, multiple snap-fit ​​protrusions can be provided, and correspondingly, multiple snap-fit ​​slots can also be provided. By having the snap-fit ​​protrusions and snap-fit ​​slots correspond one-to-one, the stability of the connection between the connection terminal 11 and the connection seat 22 can be improved through multi-point positioning.

[0046] In this embodiment, the earphone body 21 includes a sound-emitting part 211, a connecting part 212, and a battery compartment 213. The sound-emitting part 211 has a speaker structure for transmitting sound to the user's ear. The connecting part 212 is used to place the earphone 20 on the user's ear to fix the relative position of the earphone 20 and the user's ear. A battery is disposed inside the battery compartment 213, and the battery powers the sound-emitting part 211.

[0047] The two ends of the connecting part 212 are respectively connected to the sound-generating part 211 and the battery compartment 213. The connecting seat 22 is located on the side of the battery compartment 213 facing away from the connecting part 212. The connecting seat 22 can be integrally injection molded with the battery compartment 213, or it can be fixed to the connecting seat 22 by screws or snap-fit.

[0048] In this embodiment of the application, a clamping space for clamping the user's ear is formed between the connecting part 212 and the sound-emitting part 211. The connecting part 212 includes a connecting shell and a shaping member disposed in the connecting shell. The shaping member is used to make the connecting part 212 maintain the clamping space more stably.

[0049] For example, the earphone 20 may be an ear hook earphone, and the connecting part 212 is an ear hook part, wherein the sound-emitting part 211 has a first surface for conforming to the user's inner ear, and the end of the ear hook part away from the sound-emitting part 211 is offset from the first surface, so that a clamping space for clamping the user's ear is formed between the ear hook part and the sound-emitting part 211.

[0050] The ear hook portion includes an ear hook shell and a shaping component. The ear hook shell is made of an elastic material; for example, it can be made of elastomers such as silicone, liquid silicone, TPU, TPE, TPSIV, or fluoropolymer. A cavity is formed within the ear hook shell, and the shaping component is disposed within the cavity. The shaping component can change its shape when subjected to force and return to its original position when the external force is removed. The shaping component has a certain degree of stability, allowing the ear hook shell to be maintained in a certain state more stably. Thus, the shaping component is used to make the ear hook portion maintain the clamping space more stably.

[0051] Optionally, the shaping component can be made of shape memory metal, such as titanium wire, nickel-titanium alloy wire, copper-zinc alloy wire, copper-aluminum-nickel alloy wire, copper-molybdenum-nickel alloy wire, or copper-gold-zinc alloy wire. In this way, the shape memory metal component can support the shape of the ear hook shell and prevent the ear hook shell from deforming under stress.

[0052] The ear hook also includes a wire, which is located inside the wire cavity. One end of the wire is electrically connected to the battery in the battery compartment 213, and the other end of the wire is electrically connected to the sound-emitting part 211. The wire transmits the power of the battery in the battery compartment 213 to the sound-emitting part 211.

[0053] In some embodiments, the earphone 20 can also be a clip-on earphone, with the connecting part 212 serving as the clip-on portion. The clip-on portion is arched, and its central area forms an ear-clamping space. This ear-clamping space allows the earphone 20 to be held in place on the user's ear. Simultaneously, the clip-on portion is made of a flexible material with a certain degree of elasticity. Under external force, the clip-on portion undergoes elastic deformation, allowing the sound-emitting part 211 and the battery compartment 213 to move away from each other, thereby opening the ear-clamping space. When the user's ear is placed in this space, removing the external force will clamp the earphone 20 in place. In this embodiment, a shaping component can also be provided within the clip-on portion, which will not be elaborated upon here.
