[0028] 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.

[0029] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0030] 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.

[0031] In related technologies, open-back headphones are generally separate and often need to be charged with a charging case. However, the headphones cannot be used while charging, which fails to meet the needs of users.

[0032] See Figures 1 to 2 This application provides a neckband charger, including a connector 110 and a neckband assembly 120. The connector 110 has a first charging terminal 111, and the neckband assembly 120 includes a charging power supply 121 and an electrical connection line 122. The charging power supply 121 is electrically connected to the first charging terminal 111 through the electrical connection line 122. The first charging terminal 111 can be electrically connected to the earphone 200. Thus, the charging power supply 121 can charge the earphone 200 through the electrical connection line 122 and the first charging terminal 111. When the earphone 200 is an open-back earphone, it can be charged without placing the earphone 200 in the charging case, that is, the earphone 200 can be used while charging.

[0033] In this embodiment, the electrical connector 122 is a retractable cable. The length of the retractable electrical connector 122 can be freely adjusted within a certain range. Users can lengthen or shorten the power cord as needed, which greatly improves the convenience of use. In addition, since the neck thickness of different users is different, by designing the electrical connector 122 to be retractable, it can also meet the needs of different neck thicknesses within a certain range.

[0034] It should be understood that, in the embodiments of this application, the retractability of the electrical connector 122 can change the relative distance between the two ends of the electrical connector 122. For example, the middle part of the electrical connector 122 can be coiled back and forth, and the coiled part can be relatively fixed by a buckle. When the buckle is open, part of the electrical connector 122 can also be coiled back and forth, thereby making the distance between the two ends of the electrical connector 122 relatively shorter, or the coiled electrical connector 122 can be unfolded, thereby making the distance between the two ends of the electrical connector 122 relatively longer.

[0035] In some embodiments, the electrical connection wire 122 is a spring wire. As a retractable wire, the length of the spring wire can be freely adjusted according to actual needs to meet the usage requirements of different scenarios. The spring wire has good elasticity and can adapt to various bending and stretching requirements. When not in use, the spring wire can be rolled up or retracted under the action of elasticity, occupying little space and making it convenient to carry and store.

[0036] The spring wire includes an outer shell and an inner conductive wire. The charging power supply 121 and the first charging terminal 111 are electrically connected through the conductive wire. The shell, as an external component that can protect the conductive wire, can be made of an elastic material. That is, the shell can be made of silicone, liquid silicone, TPU (Thermoplastic Urethane), TPE (Thermoplastic Elastomer), TPSIV (Thermo Plastic Silicone Vulcanizate), or fluoropolymer, etc.

[0037] The flexible outer shell can tightly wrap the conductive wire, effectively preventing the wire from being damaged by external mechanical forces such as scratches, squeezing or impact. It can also withstand frequent bending and stretching, and is not easy to break or deform, thus maintaining the integrity and functionality of the conductive wire.

[0038] After the charging power supply 121 charges the earphones 200, it is necessary to replenish the charging power supply 121 with power via a power cord. In some implementations, the charging power supply 121 is equipped with a charging interface 121a. The charging interface 121a adopts a widely compatible standard (such as USB, Type-A, Type-C, etc.) so that users can use various charging cables and power adapters for charging, improving the versatility and convenience of the device. The charging interface 121a is located on the side of the charging power supply 121 facing away from the user's neck, which makes it convenient to plug in the power cord when the neckband charger 100 is hung around the user's neck, ensuring a comfortable wearing experience.

[0039] Understandably, an LED indicator can be installed on the charging power supply 121 nearby to display the charging status (such as charging in progress, fully charged, etc.), so that users can easily understand the power status of the charging power supply 121 at any time.

[0040] When charging the earphones 200, the neckband charger 100 of this embodiment may have one first charging terminal 111, which can charge two earphones 200 sequentially, or it may have two first charging terminals 111, that is, the two first charging terminals 111 can charge two earphones 200 simultaneously. In this embodiment, please refer to... Figure 2 Preferably, the neckband charger 100 has two connectors 110, and each connector 110 is provided with a first charging terminal 111. One of the first charging terminals 111 can be electrically connected to one of the two earphones 200, and the other first charging terminal 111 can be electrically connected to the other earphone 200. In this way, the charging time of the two earphones 200 can be significantly shortened.

[0041] When the neckband charger 100 has two connectors 110, the two connectors 110 are located at both ends of the electrical connection line 122. To improve force balance, the electrical connection line 122 includes a first connection end and a second connection end spaced apart. The charging power supply 121 is located between the first connection end and the second connection end, that is, the charging power supply 121 is located in the middle of the electrical connection line 122. When the charging power supply 121 is located in the middle of the electrical connection line 122, the weight distribution of the entire neckband charger 100 is more even, thereby reducing the burden on the user's neck or ears and maintaining comfort even during long-term wear. On the other hand, the charging power supply 121 in the middle position helps to improve the overall stability of the neckband charger 100, making the entire neckband charger 100 less prone to shaking.

[0042] In addition, in some embodiments, when the neckband assembly 120 is hung around the user's neck, the side of the charging power supply 121 facing the user's neck can be set in an arc shape to best fit the user's neck, thereby further improving the stability of the neckband charger 100 when it is hung around the user's neck.

[0043] It is understood that the neckband charger 100 is not limited to charging the headphones 200, but can also charge small digital cameras, action cameras and walkie-talkies. In this embodiment, the neckband charger 100 is used to charge the headphones 200 for illustrative purposes. The headphones include open-back headphones and in-ear headphones. In this embodiment, open-back headphones are used as an example for illustrative purposes.

[0044] Please see Figures 1 to 3 This application embodiment also provides an earphone assembly, including the neckband charger 100 and earphone 200 as described above. The earphone 200 has a second charging terminal 201. The connector 110 is detachably connected to the earphone 200. The first charging terminal 111 can be electrically connected to the second charging terminal 201 so that the charging power supply 121 can supply power to the earphone 200 through the electrical connection line 122.

[0045] The neckband charger 100 is detachably connected to the earphone 200 via connector 110. This detachable connection allows users to easily connect and disconnect the connector 110 from the earphone 200. Thus, after the earphone 200 is fully charged, the neckband charger 100 can be removed and stored. Furthermore, since the earphone 200 and neckband charger 100 exist as separate components, if either the earphone 200 or the neckband charger 100 is damaged or needs upgrading, only the corresponding earphone 200 or neckband charger 100 needs to be replaced.

[0046] Since the first charging terminal 111 and the second charging terminal 201 can cooperate with each other and be electrically connected, the first charging terminal 111 is described by way of example in this application embodiment.

[0047] The first charging terminal 111 can be a charging PIN, a magnetic charging plug, a Type-C connector, or a USB connector, etc. In this embodiment, no restrictions are imposed, and the specific configuration can be determined according to the actual situation.

[0048] In some embodiments, please refer to Figure 2 The connector 110 has a slot 110a, and the first charging terminal 111 is located in the slot 110a. The earphone 200 includes an earphone body 210 and a connector 220 connected to each other. The second charging terminal 201 is located on the connector 220 and is electrically connected to the earphone body 210. When the connector 110 is connected to the earphone 200, the connector 220 is at least partially inserted into the slot 110a.

[0049] The engagement of slot 110a and connector 220 ensures stable contact between the first charging terminal 111 and the second charging terminal 201, preventing the connection between the first charging terminal 111 and the second charging terminal 201 from being exposed to the outside world. This not only reduces the impact of external dust and water droplets on charging, but also reduces problems such as charging failures or sound quality degradation caused by poor contact, providing a reliable electrical connection.

[0050] The connection between the connector 220 and the headphone body 210 enhances the overall structural strength of the headphone 200. When the connector 220 is inserted into the slot 110a, the connection between the headphone 200 and the connector 110 is further secured, reducing loosening or damage caused by external forces.

[0051] It is understandable that, in order to reduce the probability of the headphones 200 falling off when connected to the neckband charger 100, in some embodiments of this application, the connector 110 is magnetically connected to the connector 220, or the connector 110 is snapped to the connector 220, or the connector 110 and the connector 220 are simultaneously magnetically connected and snapped to each other.

[0052] When the connector 110 and the connector 220 are magnetically connected, the connector 110 may be magnetic, the connector 220 may have a first cavity, and the first magnetic element may be disposed in the first cavity. The connector 110 is magnetically connected to the connector 220 through the first magnetic element. That is, the connector 110 has a magnetic metal (such as iron, nickel, cobalt, etc.), and the first magnetic element may be a magnet. The magnet is fixed in the first cavity relative to the connector 220. By attracting the magnetic metal connector 110 with the magnet, the connector 110 and the connector 220 can be connected together. Through the magnetic connection, the wear of the connector 220 and the connector 110 can be relatively low, and long-term stability and reliability can be maintained.

[0053] In another embodiment, the connector 220 may be magnetic, and the connector 110 may have a second cavity (not shown in the figure). A second magnetic element (not shown in the figure) may be disposed in the second cavity. The second magnetic element may also be a magnet. In this way, the connector 110 and the connector 220 can be connected together by the magnetic attraction between the second magnetic element and the connector 220.

[0054] In other embodiments, the connector 110 may have a second cavity containing a second magnetic element, while the connector 220 may have a first cavity containing a first magnetic element. The connector 110 is magnetically connected to the connector 220 via the first and second magnetic elements. In this case, both the connector 110 and the connector 220 contain magnetic elements, thus generating a stronger magnetic attraction between them, ensuring a secure connection. Furthermore, by rationally designing the position and strength of the first and second magnetic elements, the magnetic force distribution can be balanced, reducing connection instability caused by uneven magnetic force.

[0055] When the connector 110 and the connector 220 are snapped together, one of the connector 110 and the connector 220 is provided with a snap-fit ​​part (not shown in the figure) and the other is provided with a snap-fit ​​groove (not shown in the figure), and the snap-fit ​​part snaps into the snap-fit ​​groove.

[0056] It is understood that the connector 110 may be provided with a snap-fit ​​part and the connector 220 may be provided with a snap-fit ​​groove; or the connector 110 may be provided with a snap-fit ​​groove and the connector 220 may be provided with a snap-fit ​​part; or the connector 110 may be provided with both a snap-fit ​​part and a snap-fit ​​groove and the connector 220 may be provided with both a corresponding snap-fit ​​groove and a snap-fit ​​part. No specific limitations are made in the embodiments of this application.

[0057] The snap-fit ​​part can be a tongue-shaped structure or a hook-shaped structure, etc. In addition, multiple snap-fit ​​parts can be provided, and correspondingly, multiple snap-fit ​​slots are also provided. By having the snap-fit ​​parts and snap-fit ​​slots correspond one-to-one, the stability of the connection between the connector 110 and the connector 220 can be improved through multi-point positioning.

[0058] In some embodiments, in order for the connector 220 to be inserted smoothly and stably into the slot 110a, the opening edge of the slot 110a may be chamfered or rounded to reduce friction and resistance when the connector 220 is inserted.

[0059] In some embodiments, an elastic element may be provided on the outer side wall of the connector 220 or the inner side wall of the slot 110a. The elastic element can abut against the outer side wall of the connector 220 or the inner side wall of the slot 110a after the connector 220 is inserted into the slot 110a, thereby reducing the possibility of the connector 220 loosening or falling out in the slot 110a and enhancing the stability of the connection between the accessory and the main body.

[0060] In this embodiment, the outer wall of the connector 220 is provided with an elastic element for illustrative purposes. The elastic element can be a metal sheet or an elastic rubber ring. When the elastic element is an elastic rubber ring, the outer wall of the connector 220 is recessed inward to form a mounting groove. The elastic rubber ring can be fitted into the mounting groove. After the connector 220 is inserted into the slot 110a, the elastic rubber ring deforms and can abut against the inner wall of the slot 110a and the outer wall of the connector 220, thereby reducing the possibility of the connector 220 loosening or falling out in the slot 110a, and thus enhancing the stability of the headphones 200 and the neckband charger 100.

[0061] In addition, the elastic rubber ring can also play a certain sealing role, thereby reducing the possibility of dust and liquid entering the main body.

[0062] In some embodiments, please refer to Figure 3 The earphone 200 includes a sound-emitting part 211, a connecting part 212, and a battery compartment 213. The connecting part 212 is used to place on the user's ear to fix the relative position of the earphone 200 and the user's ear. The sound-emitting part 211 may have a speaker structure for transmitting sound to the user's ear. The battery compartment 213 contains a battery that powers the sound-emitting part 211.

[0063] 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 220 is located on the side of the battery compartment 213 facing away from the connecting part 212. The connecting seat 220 can be an integral injection molded structure with the battery compartment 213, or it can be fixed to the connecting seat 220 by means of screws or snap-fit.

[0064] When the connector 220 is close to the battery compartment 213, the second charging terminal 201 is closer to the battery in the battery compartment 213, making the entire headphone 200 structure more compact and reducing the length of the conductive wire. This not only reduces material costs but also reduces current loss during transmission.

[0065] Specifically, the connecting part 212 includes a housing and a wire. The housing is made of an elastic material, such as silicone, liquid silicone, TPU, TPE, TPSIV, or fluoropolymer. The housing forms a wire cavity, and the wire is disposed within 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 from the battery in the battery compartment 213 to the sound-emitting part 211.

[0066] In some embodiments, a shape memory metal component (not shown in the figure) may be provided inside the connecting part 212 to support the outer shell. The shape memory metal component may be 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, etc. In this way, the shape memory metal component can support the shape of the outer shell and prevent the outer shell from deforming under stress.

[0067] According to the embodiment of this application, the connecting portion 212 is made of an elastic material. When the connecting portion 212 is worn on the user's ear, the elastic deformation of the shell can absorb some of the pressure, improving wearing comfort. Furthermore, the curve of the connecting portion 212 is generally pre-designed to conform to ergonomic dimensions, providing good wearing comfort and high stability. A memory metal component is provided within the shell, which helps support the shape of the shell, preventing deformation under stress and ensuring that the curve of the connecting portion 212 conforms to the intended setting, thus guaranteeing both wearing comfort and stability.

[0068] When the earphone 200 is an open-back earphone, it can be either an ear-hook open-back earphone or an earlobe open-back earphone. When it is an ear-hook open-back earphone, the connecting part 212 is the ear hook, which is used to hang on the ear. When the earphone 200 is worn on the user's ear, the end of the battery compartment 213 away from the connecting part 212 faces the neck. In this way, when the connecting base 220 is also located on the side of the battery compartment 213 facing away from the connecting part 212, the connection between the neckband charger 100 and the earphone 200 can be more convenient.

[0069] On the other hand, when the earphone 200 is an ear-hook open-back earphone, the twisting or bending of the part where the electrical connection cable 122 is connected to the first charging terminal 111 can be reduced, thereby improving the service life of the entire neckband charger 100.

[0071] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
