[0040] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figures 1 to 3 , Figure 1 A three-dimensional structural diagram of a partial structure of an open-type earphone provided in an embodiment of the present application, Figure 2 This is a diagram of the use status of the open-type earphones provided in the embodiment of the present application. Figure 3 This is a diagram of the use status of the open-type earphones provided in the embodiment of the present application from another perspective. Figures 1 to 3 As shown, the present embodiment provides an open-type earphone, comprising two earphone bodies 20 and a rear-hanging component 10, the earphone body 20 comprising a sound-emitting component 201 and an ear-hanging component 203 connected to each other, the sound-emitting component 201 comprising a sound outlet 2012 having a sound outlet hole 2011, and the ear-hanging component 203 is used to wear the earphone body 20 on the ear of the user; when the open-type earphone is worn on the ear of the user, the sound-emitting component 201 covers the ear canal opening of the ear and does not extend into the ear canal opening, and the covering here refers to covering in a broad sense, and 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 position of the ear canal opening but not extending into the ear canal opening; wherein, the length of the rear-hanging component 10 can be adjusted. In the open-type earphones provided in the present embodiment, the length of the rear hanging component 10 can be adjusted, so that the open-type earphones provided in the present embodiment can be suitable for different groups of people, so that the open-type earphones provided in the present embodiment have a better user experience during use; in addition, in the open-type earphones provided in the present embodiment, the rear hanging component 10 is detachably connected to the ear hanging component 203, so that the open-type earphones provided in the present embodiment can be used in different scenarios, so that the open-type earphones provided in the present embodiment have better performance; in addition, the rear hanging component 10 can provide a certain clamping force to the head, such as the back of the head, so that the wearing stability and comfort of the open-type earphones provided in the present embodiment are higher.

Here, other modules included in the open-type earphone provided in this embodiment are not specifically limited.

[0044] Please continue to see Figures 4 to 7 , Figure 4 This is a schematic diagram of the three-dimensional structure of the rear hanging component in the open-type earphone provided in an embodiment of the present application. Figure 5 for Figure 4 Cross-sectional view along AA direction, Figure 6 for Figure 5 The enlarged schematic diagram of the local structure at B in the middle. Figure 7 A schematic diagram of the partial structure of the rear hanging component in the open-type earphone provided in the embodiment of the present application. In some optional embodiments, the rear hanging component 10 includes two rear hanging parts 1 and a connecting structure; one end of the two rear hanging parts 1 is detachably connected to the ear hanging parts 203 of the two earphone bodies 20, respectively, and the connecting structure connects the two rear hanging parts 1 together, and the connecting structure is slidably connected to at least one of the two rear hanging parts 1. Specifically, when the length of the rear hanging component 10 needs to be shortened, the connecting structure can be pulled; when the length of the rear hanging component 10 needs to be extended, the rear hanging part 1 can be pulled. In this way, the length of the rear hanging component 10 can be adjusted.

[0045] For the convenience of description, the two rear hanging parts 1 are respectively referred to as the first rear hanging part 1a and the second rear hanging part 1b.

[0046] It should be noted that, in some other embodiments, the first rear hanging member 1a and the second rear hanging member 1b can also be relatively extended and shortened, for example, the first rear hanging member 1a and the second rear hanging member 1b are sleeved, and when extension or shortening is required, the first rear hanging member 1a or the second rear hanging member 1b can be pulled or pushed; in other embodiments, two connecting members connected by threads at one end can be provided between the first rear hanging member 1a and the second rear hanging member 1b, and the length of the rear hanging assembly 1 can be changed by screwing the two connecting members in or out. In this embodiment, the length of the rear hanging assembly is adjusted by the above-mentioned connection structure, which will be described in detail below.

[0047] Specifically, the first rear hanger 1a and the second rear hanger 1b each include a first end and a second end, and the first end is detachably connected to the ear hanger component 203; the connection structure includes two connectors 2, specifically, the two connectors 2 include a first connector 2a and a second connector 2b, the first connector 2a is fixedly connected to the second end of the first rear hanger 1a and slidably cooperates with the second rear hanger 1b, and the second connector 2b is fixedly connected to the second end of the second rear hanger 1b and slidably cooperates with the first rear hanger 1a. In this way, when it is necessary to shorten the length of the rear hanging component 10, one hand holds the first connecting member 2a and the other hand holds 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 component 10; when it is necessary to lengthen the length of the rear hanging component 10, two hands respectively hold the second end of the first rear hanging member 1a and the second end of the second rear hanging member 1b, so that the two ends of the rear hanging component 10 move away from each other, thereby lengthening the length of the rear hanging component 10.

[0048] It should be noted that the first rear hanging member 1a and the second rear hanging member 1b can be made of wire materials such as braided wires. Here, the material of the rear hanging member 1 is not specifically limited.

[0049] Please continue to see Figure 8 , Figure 8 A schematic diagram of the three-dimensional structure of the connection seat in the open earphone provided in the embodiment of the present application. In some embodiments, the connector 2 includes a connection seat 21, and the connection seat 21 includes a first connector 212 and a second connector 215 connected to each other; the first connector 212 is fixedly connected to the second end of one of the two rear hangers 1; the second connector 215 is provided with a first through hole 211 for the other of the two rear hangers 1 to pass through, wherein the first through hole 211 is interference-fitted with the rear hanger 1. In this way, the length of the rear hanger assembly 10 can be changed when the connector 2 is pulled.

[0050] 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 is fixedly connected to the second end of the first rear hanger 1a, and the second connector 215 of the first connector 2a is 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 is fixedly connected to the second end of the second rear hanger 1b, and the second connector 215 of the second connector 2b is provided with a first through hole 211 for the first rear hanger 1a to pass through.

[0051] 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 via the connecting portion 214, and a dimension of the first connecting body 212 in the length direction of the rear hanger 1 is greater than a dimension of the supporting portion 213 in the length direction of the rear hanger 1, a portion of the first via 211 is opened on the connecting portion 214, and another portion of the first via 211 is opened on the supporting portion 213.

[0052] In some embodiments, in order to improve the hand feeling when a person pulls the connecting member 2, rounded corners are used at the corners of the first connecting body 212 and the supporting portion 213. Here, the specific structure of the connecting member 2 is not limited.

[0053] In order to maintain the smoothness of the sliding of the connector 2 and to make the neck or head of a person feel more comfortable when it contacts the connector 2, the connector 2 also includes a protective cover 22, that is, the first connector 2a and the second connector 2b can both include a connector seat 21 and a protective cover 22, and the hardness of the protective cover 22 is less than the hardness of the connector seat 21; the protective cover 22 is wrapped around the outside of the connector seat 21 and has two second through holes 222, and the two second through holes 222 are respectively used for a rear hanging member 1 to pass through. In this way, not only can the smoothness of the connector 2 during the sliding process be ensured, but also the comfort of the person when the connector 2 contacts the neck can be improved.

[0054] It should be noted that the material used for the protective cover 22 can refer to the material of the main body 12. Here, the material of the protective cover 22 is not limited.

[0055] Please continue to see Fig. 9 , Fig. 9 A schematic diagram of the three-dimensional structure of the connector in the open-type earphone 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, the shape of the anti-slip portion 221 is not specifically limited. 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 hanging part 1.

[0056] The anti-slip portion 221 is integrally formed on the protective cover 22, so as to facilitate processing and forming the protective cover 22. Here, the forming method of the protective cover 22 is not specifically limited.

[0057] Furthermore, in order to further increase the friction between the connecting member 2 and the human hand, the anti-skid portion 221 may be multiple, and specifically, the multiple anti-skid portions 221 may include two groups of anti-skid portions arranged opposite to each other; each anti-skid portion group includes multiple anti-skid portions 221 arranged at intervals along the length direction of the rear hanging member 1. In this way, not only can the friction between the human hand and the connecting member 2 be further increased, but also when the human hand slides on the connecting member 2, the friction generated between the human hand and the connecting member 2 is distributed more evenly, thereby improving the efficiency of adjusting the length of the rear hanging member 1.

[0058] It should be noted that the above-mentioned anti-skid portion group may include four anti-skid portions 221, six anti-skid portions 221, eight anti-skid portions 221, etc. Here, there is no specific limitation on the number of anti-skid portions 221 included in each anti-skid portion group.

[0059] Since in the related art, the sound-generating component 201 and the ear-hook component 203 are detachably connected, and the ear-hook component 203 is fixedly connected to the rear hanger 1, the rear hanger 1 cannot be separated from the earphone body 20, which makes the open earphone inconvenient to use. 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. In this way, the convenience of using the open earphone can be improved, so that the open earphone provided by this embodiment can be applied to a variety of different scenarios.

[0060] Specifically, a male component is provided at the end of the rear hanging component 10, and a female component is provided at one end of the ear hanging component 203 facing the end of the rear hanging component 10; the male component and the female component are snap-connected to detachably connect the end of the rear hanging component 10 and the corresponding ear hanging component 203.

[0061] Furthermore, the male component includes a plug 13 formed on the end of the rear hanging component 10; the female component includes a socket 202 and an elastic snap-fitting part 30 arranged inside the socket 202, and 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 and connected with the elastic snap-fitting part 30.

[0062] 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, and the specific type of the elastic engaging member 30 is not limited here.

[0063] Please continue to see Figures 10 to 12 , Fig.10 This is a schematic diagram of the structure of the socket in the open-type earphone provided in the embodiment of the present application. Fig.11 An exploded view of a socket in an open-type headset provided in an embodiment of the present application, Fig.12 for Fig.10Cross-sectional view along CC direction. In some specific embodiments, the socket 202 may include a base 2021 and a first end cover 2022 and a second end cover 2023 detachably connected to both ends of the base 2021. Specifically, the first end cover 2022 and the second end cover 2023 may be connected to the base 2021 by 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.

A receiving cavity 2024 is enclosed between the base 2021, the first end cover 2022 and the second end cover 2023, and the plug hole 2030 is opened on the second end cover 2023 and communicates with the receiving cavity 2024.

[0064] 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 connected to the base body 2036, the base body 2036, the first end cover 2022 and the second end cover 2023 enclose 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 correspondingly, the side of the first end cover 2022 facing the positioning portion 2025 has a recessed cavity 2027 for 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.

[0065] Please continue to see Figures 13 to 16 , Fig.13 for Figure 7 The enlarged schematic diagram of the local structure at D in the middle. Fig.14 A schematic diagram of the matching relationship between the plug socket and the elastic engaging member in the open-type earphone provided in an embodiment of the present application, Fig.15 for Fig.14 Cross-sectional view along EE direction, Fig.16 for Fig.14Cross-sectional view along the FF direction. In some embodiments, a recessed portion 131 is formed on the side of the plug 13; the elastic snap-fitting member 30 has a protrusion 301 that can be inserted into the recessed portion 131. In some optional embodiments, the cross-sectional shape of the plug 13 can be rectangular, and recessed portions 131 are provided on both sides of the plug 13 along its length direction. Accordingly, the elastic snap-fitting member 30 has two protrusions 301, and one protrusion 301 corresponds to one recessed portion 131. In this way, a reliable connection between the plug 13 and the elastic snap-fitting member 30 can be achieved, so as to achieve a reliable connection between the earphone body 20 and the rear hanger 1.

[0066] In some embodiments, the above-mentioned recessed portion 131 may be a recessed notch formed on the side of the plug 13, and the opening of the notch may be circular. Here, the shape of the recessed portion 131 is not specifically limited.

[0067] In this embodiment, the protrusion 301 is located in the second accommodating cavity 2029 , so the plug hole 2030 is communicated with the second accommodating cavity 2029 , and the plug 13 is inserted into the second accommodating cavity 2029 through the plug hole 2030 and is engaged with the elastic engaging member 30 .

[0068] The structure of the elastic engaging member 30 will be described in detail below.

[0069] Please continue to see Fig.17 , Fig.17 A schematic diagram of the three-dimensional structure of an elastic snap-fit ​​member in an open-type earphone provided in an embodiment of the present application. Specifically, the elastic snap-fit ​​member 30 includes a snap-fit ​​body 302, a first snap-fit ​​arm 303, and a second snap-fit ​​arm 304, wherein the first snap-fit ​​arm 303 and the second snap-fit ​​arm 304 are both connected to a side of the snap-fit ​​body 302 close to the rear hanging member 1, wherein the snap-fit ​​body 302 is located in the first accommodating cavity 2028, and the snap-fit ​​body 302 has a positioning hole 3021 for the positioning column 2026 to pass through, and the circumferential side of the positioning portion 2025 is formed with a first connecting hole 2031 and a second connecting hole 2032 that connect the first accommodating cavity 2028 and the second accommodating cavity 2029, and the first snap-fit ​​arm 303 can pass through the first connecting hole 2031 to extend into the second accommodating cavity 2029, and the second snap-fit ​​arm 304 can pass through the second connecting hole 2032 to extend into the second accommodating cavity 2029.

[0070] 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.

[0071] In order to realize the detachable connection between the elastic engaging member 30 and the socket 202, a protrusion 2033 protruding toward the first engaging arm 303 is provided in the accommodating cavity 2024. Specifically, a protrusion 2033 is provided on the side wall of the first connecting hole 2031, and correspondingly, the first engaging arm 303 has a engaging hole 3031 engaged with the protrusion 2033. In this way, the detachable connection between the elastic engaging member 30 and the socket 202 can be realized.

[0072] In some embodiments, in order 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.

[0073] It should be noted that, in the present embodiment, two relatively distributed recessed portions 131 are provided on the plug 13, and therefore, two relatively distributed second clamping arms 304 should also be connected to the clamping body 302. In order to improve the connection reliability between the elastic clamping member 30 and the socket 202, two relatively distributed first clamping arms 303 may be connected to the clamping body 302, wherein the first clamping arm 303 and the second clamping arm 304 are arranged adjacent to each other. In some other embodiments, the number of the first clamping arm 303 and the second clamping arm 304 may also be three, four, etc. Here, the number of the first clamping arm 303 and the second clamping arm 304 is not specifically limited.

[0074] Please continue to see Fig.18 , Fig.18 A schematic diagram of the three-dimensional structure of the base in the open earphone provided in the 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 connection with the elastic engaging member 30, in the present embodiment, a guide groove 2034 facing the plug hole 2030 can be formed on the side of the positioning portion 2025 facing the plug hole 2030, so that 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 hanging member 1.

[0075] 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 with the guide groove 2034 more reliably to enhance the guiding effect of the guide groove 2034; in addition, the end of the plug 13 can be abutted against the bottom wall of the guide groove 2034, so that the engaging stroke of the plug 13 can be limited, thereby enhancing the connection efficiency between the earphone body 20 and the rear hanger 1.

[0076] Furthermore, when assembling the connector 202 and the elastic snap-fitting member 30 , in order to position the elastic snap-fitting member 30 and the first end cover 2022 , a positioning cavity 2035 cooperating with the snap-fitting body 302 may be formed on the first end cover 2022 , and a recessed cavity 2027 is formed on the bottom wall of the positioning cavity 2035 .

[0077] 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, and then realize the detachable connection between the elastic snap-fit ​​part 30 and the base 2021 through the cooperation between the protrusion 2033 and the snap-fit ​​hole 3031; then, install the first end cover 2022 and the second end cover 2023 on the base 2021; finally, connect the assembled elastic snap-fit ​​part and the connector 202 together on the sound-emitting component 201.

[0078] 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 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 means that the plug 13 and the elastic engaging member 30 are engaged in place.

[0079] 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 a direction from the end close to the rear hanging component 10 to the end away from the rear hanging component 10 .

[0080] In some optional embodiments, in order to protect the plug 13, a protective shell 14 is provided on the end of the rear hanging component 10, and the end of the protective shell 14 facing the female head component is open, and part of the structure of the male head component is exposed outside the protective shell 14 through the opening; a matching cavity 141 matching the outer contour shape of the socket 202 is formed in the protective shell 14. In this way, not only can the plug 13 be protected to prevent the plug 13 from being worn or damaged to a certain extent, but also the snap connection between the plug 13 and the elastic snap member 30 will not be affected; in addition, the protective shell 14 and the socket 202 can be matched reliably, thereby improving the connection reliability between the rear hanging component 10 and the earphone body 20.

[0081] like Figure 2 and Figure 3 As shown, generally, the sound-emitting component 201 includes a sound-emitting shell 2013 and a sound-emitting unit (not shown in the figure) 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, and a pressure relief port 2014 connected to the rear cavity is arranged on the sound-emitting shell 2013; when the open-type earphone provided in this embodiment is worn on the ear, 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 to achieve less blocking of external sound from entering the external auditory canal opening. Obviously, sound leakage is also 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 effectively reduce the sound leakage near the front side of the ear and the external auditory canal opening, thereby improving the user experience of the open-type earphone provided in this embodiment.

[0082] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
