[0028] In the related art, open-back headphones consist of a neckband and a headphone body, with the headphone body attached to both ends of the neckband. The neckband is a complete wire, and the portion of the neckband that contacts the human body is an integrally molded structure. The headphone body includes a sound-producing component and an earhook component, which are detachably connected to the earhook, while the earhook is fixedly connected to the neckband. However, in these open-back headphones, the length of the neckband cannot be adjusted, which affects the performance of the open-back headphones, resulting in poor performance.

[0029] To solve the above problems, the embodiment of the present application provides an open-ear headphone, which can adjust the length of the rear hanging component, and the rear hanging component can provide appropriate clamping force to the head, which can improve the versatility of the open-ear headphone provided by the embodiment of the present application so that it is suitable for more people, and can improve the performance of the open-ear headphone provided by the embodiment of the present application. That is, the open-ear headphone provided by the embodiment of the present application has better performance.

[0030] It should be noted that the open-ear headphones provided in the embodiment of the present application can be worn not only on the head, but also on the neck. Here, there is no limitation on the wearing scenario of the open-ear headphones provided in the embodiment of the present application.

[0031] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] Please refer to Figures 1 to 3. Figure 1 is a schematic diagram of the three-dimensional structure of the partial structure of the open-type earphone provided by an embodiment of the present application, Figure 2 is a diagram of the use state of the open-type earphone provided by an embodiment of the present application, and Figure 3 is a diagram of the use state of the open-type earphone provided by an embodiment of the present application from another perspective. As shown in Figures 1 to 3, this embodiment provides an open-type earphone, including two earphone bodies 20 and a back-hanging assembly 10. The earphone body 20 includes a sound-emitting component 201 and an ear-hanging component 203 connected to each other. The sound-emitting component 201 includes a sound-emitting portion 2012, and the sound-emitting portion 2012 has a sound-emitting hole 2011. The ear-hanging component 203 is configured to wear the earphone body 20 on the user's ear; when the open-type earphone is worn on the user's ear, the sound-emitting component 201 covers the ear canal opening of the ear and does not extend into the ear canal opening. The covering here refers to covering in a broad sense. It can be understood that the position of the sound-emitting component 201 corresponds to the position of the ear canal opening, roughly covering the ear canal opening but not extending into the ear canal opening; wherein the length of the back-hanging assembly 10 is adjustable.

[0033] In the open-ear headphones provided in this embodiment, the length of the rear hanging component 10 can be adjusted, thereby improving the versatility of the open-ear headphones provided in this embodiment, so that they are suitable for different people, and can improve the experience of the open-ear headphones provided in this embodiment during use; in addition, in the open-ear headphones provided in this embodiment, the rear hanging component 10 and the ear hanging component 203 are detachably connected, thereby improving the multi-scenario applicability of the open-ear headphones provided in this embodiment, thereby improving the use performance of the open-ear headphones provided in this embodiment; in addition, the rear hanging component 10 can provide a certain clamping force to the head, such as the back of the head, which can improve the wearing stability and comfort of the open-ear headphones provided in this embodiment.

[0034] More specifically, when the open-ear headphones provided in this embodiment are worn on the user's ears, the sound outlet 2012 is located within the user's cavum conchae and abuts against the antihelix, tragus, and antitragus of the ear. Thus, when the open-ear headphones provided in this embodiment are subjected to external forces or the wearer's inertia from running or jumping, the earphone body 20 will be blocked by the tragus, antitragus, and antihelix, allowing the earphone body 20 to be securely worn on the ear. This improves the wearing stability of the open-ear headphones provided in this embodiment and, to a certain extent, prevents the earphone body 20 from being lost.

[0035] It should be noted that the open-ear headphones provided in this embodiment can be Bluetooth headphones, such as air-conduction Bluetooth headphones. When the open-ear headphones are Bluetooth headphones, the open-ear headphones provided in this embodiment can also include a charging box that matches the headphone body 20, or the headphone body 20 can be provided with a charging port to charge the headphone body 20 via an external power source. Here, there is no specific limitation on other modules included in the open-ear headphones provided in this embodiment.

[0036] Please continue to refer to Figures 4 to 7. Figure 4 is a schematic diagram of the three-dimensional structure of the back-hanging assembly in the open-ear headphones provided by an embodiment of the present application. Figure 5 is a cross-sectional view of Figure 4 along the AA direction. Figure 6 is an enlarged schematic diagram of the partial structure at point B in Figure 5. Figure 7 is a schematic diagram of the partial structure of the back-hanging assembly in the open-ear headphones provided by an embodiment of the present application. In some optional embodiments, the back-hanging assembly 10 includes a connecting structure 3 and two back-hanging parts 1. One end of each back-hanging part 1 is detachably connected to the earhook components 203 of the two earphone bodies 20. The connecting structure 3 connects the other ends of the two back-hanging parts 1 together, and the connecting structure 3 is slidably connected to at least one of the two back-hanging parts 1. Specifically, to shorten the length of the back-hanging assembly 10, the connecting structure 3 is pulled; to lengthen the length of the back-hanging assembly 10, the back-hanging part 1 is pulled. In this way, the length of the back-hanging assembly 10 can be adjusted.

[0037] For the convenience of description, the two rear hangers 1 are respectively referred to as the first rear hanger 1A and the second rear hanger 1B.

[0038] It should be noted that in some other embodiments, the first rear hanger 1A and the second rear hanger 1B can also be relatively extended and shortened. For example, the first rear hanger 1A and the second rear hanger 1B are sleeved together, and when extension or shortening is required, the first rear hanger 1A or the second rear hanger 1B can be pulled or pushed. In other embodiments, two connectors with one end connected by a thread can be provided between the first rear hanger 1A and the second rear hanger 1B, and the length of the rear hanger assembly 1 can be changed by screwing the two connectors in or out. In this embodiment, the length of the rear hanger assembly is adjusted through the above-mentioned connection structure 3, which will be described in detail below.

[0039] Specifically, the first rear hanger 1A and the second rear hanger 1B each include a first end 11 and a second end 12, and the first end 11 is detachably connected to the ear hanger component 203; the connecting structure 3 includes two connecting parts 2, specifically, the two connecting parts 2 include a first connecting part 2A and a second connecting part 2B, the first connecting part 2A is fixedly connected to the second end 12 of the first rear hanger 1A, and slides with the second rear hanger 1B, the second connecting part 2B is fixedly connected to the second end 12 of the second rear hanger 1B, and slides with the first rear hanger 1A. In this way, when it is necessary to shorten the length of the rear hanging assembly 10, one hand pulls the first connecting member 2A and the other hand pulls the second connecting member 2B, so that the first connecting member 2A and the second rear hanging member 1B slide, and the second connecting member 2B and the first rear hanging member 1A slide, thereby shortening the length of the rear hanging assembly 10; when it is necessary to lengthen the length of the rear hanging assembly 10, two hands respectively pull the second end 12 of the first rear hanging member 1A and the second end 12 of the second rear hanging member 1B, so that the two ends of the rear hanging assembly 10 move away from each other, thereby lengthening the length of the rear hanging assembly 10.

[0040] It should be noted that both the first rear hanger 1A and the second rear hanger 1B can be made of wire materials such as braided wire.

[0041] Please continue to refer to Figure 8, which is a schematic diagram of the three-dimensional structure of the connector in the open-back headphones provided in an embodiment of the present application. In some embodiments, the connector 2 includes a connector 21, which includes a first connector 212 and a second connector 215. The first connector 212 is fixedly connected to the second end 12 of one of the two rear hangers 1. The second connector 215 defines a first through-hole 211 for the other of the two rear hangers 1 to pass through. The first through-hole 211 has an interference fit with the rear hanger 1. In this way, the length of the rear hanger assembly 10 can be changed only when the connector 2 is pulled.

[0042] Specifically, taking two connectors 2 as an example, the two connectors 2 may include a first connector 2A and a second connector 2B, the first connector 2A's first connector body 212 being fixedly connected to the second end 12 of the first rear hanger 1A, and the second connector 215 of the first connector 2A being provided with a first through hole 211 for the second rear hanger 1B to pass through; the first connector 212 of the second connector 2B being fixedly connected to the second end 12 of the second rear hanger 1B, and the second connector 215 of the second connector 2B being provided with a first through hole 211 for the first rear hanger 1A to pass through.

[0043] Furthermore, the second connecting body 215 includes a supporting portion 213 and a connecting portion 214. The first connecting body 212 and the supporting portion 213 are connected through the connecting portion 214. In the length direction of the rear hanger 1, the size of the first connecting body 212 is larger than the size of the supporting portion 213. Part of the first through hole 211 is opened on the connecting portion 214, and the other part of the first through hole 211 is opened on the supporting portion 213.

[0044] In some embodiments, in order to improve the hand feeling when the connecting member 2 is pulled by a human hand, rounded corners are adopted at the edges and corners of the first connecting body 212 and the supporting portion 213. The specific structure of the connecting member 2 is not limited here.

[0045] In order to maintain the smooth sliding of the connector 2 and enhance the comfort of the neck or head when the connector 2 is in contact with the connector 2, the connector 2 may further include a protective cover 22. That is, the first connector 2A and the second connector 2B may each include a connector base 21 and a protective cover 22. The hardness of the protective cover 22 is less than that of the connector base 21. The protective cover 22 is wrapped around the outside of the connector base 21 and has two second through holes 222. The two second through holes 222 are respectively configured to allow a rear hanging member 1 to pass through. In this way, the smooth sliding of the connector 2 is ensured, and the comfort of the person when the connector 2 contacts the neck is enhanced.

[0046] It should be noted that the material used for the protective cover 22 can refer to the material of the main body 12. Here, there is no limitation on the material of the protective cover 22.

[0047] Please continue to refer to Figure 9, which is a schematic diagram of the three-dimensional structure of the connector in the open-type earphones provided in an embodiment of the present application. When the connector 2 is slid, the protective cover 22 is in contact with the human hand. Therefore, in order to facilitate the sliding of the connector 2, in some optional embodiments, an anti-slip portion 221 is provided on the outer wall surface of the protective cover 22, such as a strip-shaped anti-slip portion. Here, there is no specific restriction on the shape of the anti-slip portion 221. In this way, by forming the anti-slip portion 221 on the surface of the protective cover 22, the friction between the human hand and the protective cover 22 can be increased, which facilitates the sliding of the connector 2 and further facilitates the adjustment of the length of the rear hanger 1.

[0048] The anti-slip portion 221 is integrally formed on the protective cover 22, so as to facilitate processing and molding of the protective cover 22. Here, there is no specific limitation on the molding method of the protective cover 22.

[0049] Furthermore, to further increase the friction between the connector 2 and the hand, multiple anti-slip portions 221 may be provided. Specifically, the multiple anti-slip portions 221 may include two groups of anti-slip portions, which are arranged opposite each other. Each anti-slip group includes multiple anti-slip portions 221, and the multiple anti-slip portions 221 are spaced apart along the length of the rear hanger 1. This not only further increases the friction between the hand and the connector 2, but also, when the hand slides on the connector 2, the friction generated between the hand and the connector 2 is more evenly distributed, thereby improving the efficiency of adjusting the length of the rear hanger 1.

[0050] It should be noted that the above-mentioned anti-slip portion group may include four anti-slip portions 221, six anti-slip portions 221, or eight anti-slip portions 221, etc. Here, there is no specific limitation on the number of anti-slip portions 221 included in each anti-slip portion group.

[0051] In the related art, the sound-producing component 201 and the ear hook component 203 are detachably connected, while the ear hook component 203 is fixedly connected to the rear hanger 1. Therefore, the rear hanger 1 cannot be separated from the earphone body 20, making the use of open-back headphones relatively inconvenient. Therefore, in this embodiment, the two ends of the rear hanger assembly 10 are detachably connected to the ear hook components 203 of the two earphone bodies 20. This improves the convenience of use of the open-back headphones and enhances the applicability of the open-back headphones provided by this embodiment in multiple scenarios.

[0052] Specifically, a male component 40 is provided at the end of the rear hanging component 10, and a female component 50 is provided at one end of the ear hanging component 203 facing the rear hanging component 10; the male component 40 and the female component 50 are snap-connected to detachably connect the end of the rear hanging component 10 and the corresponding ear hanging component 203.

[0053] Furthermore, the male component 40 includes a plug 13, which is formed at the end of the rear hanging component 10; the female component 50 includes a socket 202 and an elastic snap-fit ​​component 30, which is arranged inside the socket 202. The socket 202 has a socket hole 2030, and the plug 13 extends into the socket 202 through the socket hole 2030 and is snap-fitted with the elastic snap-fit ​​component 30.

[0054] It should be noted that the elastic engaging member 30 may be a metal spring. In some other embodiments, the elastic engaging member 30 may also be other types of elastic members. The specific type of the elastic engaging member 30 is not limited here.

[0055] Please continue to refer to Figures 10 to 12. Figure 10 is a structural schematic diagram of the socket in the open-type earphones provided in an embodiment of the present application. Figure 11 is an exploded view of the socket in the open-type earphones provided in an embodiment of the present application. Figure 12 is a cross-sectional view of Figure 10 along the CC direction. In some specific embodiments, the socket 202 may include a base 2021, a first end cover 2022 and a second end cover 2023, the first end cover 2022 and the second end cover 2023 being detachably connected to the two ends of the base 2021, specifically, the first end cover 2022 and the second end cover 2023 can be connected to the base 2021 by a threaded connection, wherein the base 2021 is connected to the sound-emitting component 201, specifically, the base 2021 and the sound-emitting component 201 are detachably connected, for example, by a snap connection or a threaded connection, the first end cover 2022 is located on the side close to the sound-emitting component 201, and the second end cover 2023 is located on the side close to the end of the rear hanging component 10, a accommodating cavity 2024 is formed between the base 2021, the first end cover 2022 and the second end cover 2023, and the socket hole 2030 is opened on the second end cover 2023 and is connected to the accommodating cavity 2024.

[0056] In some embodiments, in order to position the base 2021 and the first end cover 2022, the base 2021 includes a base body 2036 and a positioning portion 2025, the positioning portion 2025 is connected to the base body 2036, and the base body 2036, the first end cover 2022 and the second end cover 2023 form a receiving cavity 2024, and the positioning portion 2025 is located in the receiving cavity 2024 to form a first receiving cavity 2028 between the positioning portion 2025 and the first end cover 2022, and a second receiving cavity 2029 between the positioning portion 2025 and the second end cover 2023, and a positioning column 2026 is provided on the side of the positioning portion 2025 facing the first end cover 2022, and accordingly, a concave cavity 2027 is provided on the side of the first end cover 2022 facing the positioning portion 2025, and the concave cavity 2027 is configured to allow the positioning column 2026 to extend into. In this way, the base 2021 and the first end cover 2022 can be positioned so as to connect the base 2021 and the first end cover 2022 together.

[0057] Please continue to refer to Figures 13 to 16. Figure 13 is an enlarged schematic diagram of the partial structure at point D in Figure 7. Figure 14 is a schematic diagram of the mating relationship between the plug socket and the elastic engaging member in the open-ear headphones provided by an embodiment of the present application. Figure 15 is a cross-sectional view of Figure 14 along the EE direction, and Figure 16 is a cross-sectional view of Figure 14 along the FF direction. In some embodiments, a recessed portion 131 is formed on the side of the plug 13; the elastic engaging member 30 has a protrusion 301 that can snap into the recessed portion 131. In some optional embodiments, the cross-sectional shape of the plug 13 can be rectangular, and the recessed portion 131 is provided on both sides of the plug 13 along its length. Accordingly, the elastic engaging member 30 has two protrusions 301, one protrusion 301 corresponding to each recessed portion 131. In this way, a reliable connection between the plug 13 and the elastic engaging member 30 can be achieved, thereby achieving a reliable connection between the earphone body 20 and the rear hanger 1.

[0058] In some embodiments, the recessed portion 131 may be a recessed notch formed on the side of the plug 13 , and the opening of the recessed notch may be circular. The shape of the recessed portion 131 is not particularly limited.

[0059] In this embodiment, the protrusion 301 is located in the second accommodating cavity 2029 , so the insertion hole 2030 is communicated with the second accommodating cavity 2029 , and the plug 13 is inserted into the second accommodating cavity 2029 through the insertion hole 2030 and is engaged with the elastic engaging member 30 .

[0060] The structure of the elastic engaging member 30 will be described in detail below.

[0061] Please continue to refer to Figure 17, which is a schematic diagram of the three-dimensional structure of the elastic snap-fitting member in the open-type earphone provided in an embodiment of the present application. Specifically, the elastic snap-fitting part 30 includes a snap-fitting body 302, a first snap-fitting arm 303 and a second snap-fitting arm 304, wherein the first snap-fitting arm 303 and the second snap-fitting arm 304 are both connected to one side of the snap-fitting body 302 close to the rear hanger 1, wherein the snap-fitting body 302 is located in the first accommodating cavity 2028, and the snap-fitting body 302 has a positioning hole 3021, and the positioning hole 3021 is configured for the positioning column 2026 to pass through, and a first connecting hole 2031 and a second connecting hole 2032 are formed on the peripheral side of the positioning portion 2025, and the first connecting hole 2031 and the second connecting hole 2032 connect the first accommodating cavity 2028 and the second accommodating cavity 2029, and the first snap-fitting arm 303 can pass through the first connecting hole 2031 and extend into the second accommodating cavity 2029, and the second snap-fitting arm 304 can pass through the second connecting hole 2032 and extend into the second accommodating cavity 2029.

[0062] The protrusion 301 is formed on the second clamping arm 304, is located in the second accommodating cavity 2029, and protrudes toward the central axis of the elastic clamping member 30. It should be noted that the protrusion 301 can be formed on the second clamping arm 304 by bending or stamping.

[0063] In order to achieve a detachable connection between the elastic engaging member 30 and the socket 202, a protrusion 2033 is provided in the accommodating cavity 2024. The protrusion 2033 protrudes toward the first engaging arm 303. Specifically, the side wall of the first connecting hole 2031 is provided with a protrusion 2033. Correspondingly, the first engaging arm 303 has a protrusion that engages with the engaging hole 3031. The engaging hole 3031 engages with the protrusion 2033. In this way, a detachable connection between the elastic engaging member 30 and the socket 202 can be achieved.

[0064] In some embodiments, to improve the connection reliability between the elastic engaging member 30 and the socket 202, the end of the first engaging arm 303 that is not connected to the engaging body 302 extends toward the side wall of the second accommodating cavity 2029. In this way, the connection between the elastic engaging member 30 and the socket 202 is more reliable.

[0065] It should be noted that, since the plug 13 is provided with two recessed portions 131 in this embodiment, and the two recessed portions 131 are arranged opposite each other, the engaging body 302 should also be connected to two second engaging arms 304, and the two second engaging arms 304 should be arranged opposite each other. Furthermore, to improve the connection reliability between the elastic engaging member 30 and the socket 202, two first engaging arms 303 can be connected to the engaging body 302, and the two first engaging arms 303 are arranged opposite each other, wherein the first engaging arms 303 and the second engaging arms 304 are arranged adjacent to each other. In some other embodiments, the number of the first engaging arms 303 and the second engaging arms 304 can also be three, four, etc. The number of the first engaging arms 303 and the second engaging arms 304 is not specifically limited.

[0066] Please continue to refer to Figure 18, which is a schematic diagram of the three-dimensional structure of the base of the open-type earphone provided in an embodiment of the present application. In some embodiments, in order to facilitate the insertion of the plug 13 into the second accommodating cavity 2029 through the plug hole 2030 and the engagement with the elastic engaging member 30, in this embodiment, a guide groove 2034 can be formed on the side of the positioning portion 2025 facing the plug hole 2030. The guide groove 2034 is arranged opposite to the plug hole 2030. In this way, when the plug 13 is connected to the elastic engaging member 30, it can guide the movement direction of the plug 13 to a certain extent, improve the engagement efficiency between the plug 13 and the elastic engaging member 30, and further improve the connection and disassembly efficiency between the earphone body 20 and the rear hanger 1.

[0067] It should be noted that the shape of the above-mentioned guide groove 2034 is adapted to the outer contour of the plug 13, so that when the plug 13 is engaged with the elastic engaging member 30, the plug 13 can fit more reliably with the guide groove 2034, thereby improving the guiding effect of the guide groove 2034; in addition, the end of the plug 13 can be supported on the bottom wall of the guide groove 2034, so that the engaging stroke of the plug 13 can be limited, thereby improving the connection efficiency between the earphone body 20 and the rear hanger 1.

[0068] Furthermore, when assembling the socket 202 and the elastic snap-fit ​​member 30, in order to position the elastic snap-fit ​​member 30 and the first end cover 2022, a positioning cavity 2035 can be formed on the first end cover 2022, the positioning cavity 2035 cooperates with the snap-fit ​​body 302, and the concave cavity 2027 is formed on the bottom wall of the positioning cavity 2035.

[0069] Specifically, when assembling the earphone body 20, first, install the elastic snap-fit ​​part 30 on the base 2021, and position it through the cooperation between the positioning column 2026 and the positioning hole 3021. Then, through the cooperation between the protrusion 2033 and the snap-fit ​​hole 3031, a detachable connection between the elastic snap-fit ​​part 30 and the base 2021 is achieved; thereafter, install the first end cover 2022 and the second end cover 2023 on the base 2021; finally, connect the assembled elastic snap-fit ​​part 30 and the connector 202 together to the sound-emitting component 201.

[0070] When connecting the earphone body 20 with the rear hanging component 10, the plug 13 is inserted into the second accommodating cavity 2029 along the depth direction of the guide groove 2034, and is engaged with the anti-slip portion 221 on the elastic engaging member 30. When the end of the plug 13 abuts against the bottom wall of the guide groove 2034, it indicates that the plug 13 and the elastic engaging member 30 are engaged in place.

[0071] It should be noted that, in some embodiments, in order to improve the overall aesthetics of the earphone body 20 , the outer diameter of the socket 202 gradually increases in the direction from the end close to the rear hanging component 10 to the end away from the rear hanging component 10 .

[0072] In some optional embodiments, to protect the plug 13, a protective shell 14 is provided at the end of the rear-hanging assembly 10. The end of the protective shell 14 facing the female assembly 50 is open 142, and part of the structure of the male assembly 40 is exposed outside the protective shell 14 through the opening 142. A mating cavity 141 is formed within the protective shell 14, and the mating cavity 141 matches the outer contour of the socket 202. This not only protects the plug 13 to prevent wear or damage to a certain extent, but also does not affect the snap connection between the plug 13 and the elastic snap member 30. In addition, it can also improve the mating reliability between the protective shell 14 and the socket 202, and improve the connection reliability between the rear-hanging assembly 10 and the earphone body 20.

[0073] As shown in Figures 2 and 3, generally, the sound-emitting component 201 includes a sound-emitting shell 2013 and a sound-emitting unit (not shown in the figures). The sound-emitting unit is arranged in the sound-emitting shell. The sound-emitting unit divides the internal space of the sound-emitting shell 2013 into a front cavity and a rear cavity. The sound outlet 2011 is connected to the front cavity. The sound-emitting shell 2013 is provided with a pressure relief port 2014, which is connected to the rear cavity. When the open earphones provided in this embodiment are worn on the ears, the pressure relief port 2014 is closer to the user's external auditory canal opening than the sound outlet 2011. In the wearing state, the sound-emitting shell 2013 is at a considerable distance from the external auditory canal opening, so as to less block external sounds from entering the external auditory canal opening. Obviously, sound leakage is more likely to occur between the generating component 201 and the external auditory canal opening. In the embodiment of the present application, since the pressure relief port 2014 is closer to the user's external auditory canal opening than the sound outlet 2011, it can more effectively reduce the sound leakage near the front of the ear and the external auditory canal opening, thereby improving the user experience of the open-ear headphones provided by this embodiment.
