In this case, the transducing assembly faces the pinna of the user, and the first contact surface contacts the tragus of the user.

[0005] In some embodiments, the radius of the curvature of the first contact surface ranges from 30 mm to 40 mm.

[0006] In some embodiments, the earphone further comprises an ear hook connected to the transducing assembly. The ear hook comprises a flexible member, which comprises a connecting end and an abutting end. The connecting end is connected to the transducing assembly. The abutting end first extends away from the transducing assembly, then bends and extends towards the transducing assembly, and then bends and extends away from the transducing assembly.

[0007] In some embodiments, an acoustic outlet hole is arranged on the first contact surface. The angle between the normal of the plane on which the acoustic outlet hole is arranged and the plane on which the first cross section of the flexible member is arranged ranges from 65° to 75°.

[0008] In some embodiments, an acoustic outlet hole is arranged on the first contact surface. The angle between the normal of the plane on which the acoustic outlet hole is arranged and the plane on which the second cross section of the flexible member is arranged ranges from 5° to 15°.

[0009] In some embodiments, the maximum distance between the side of the flexible member close to the connecting end and the transducing assembly ranges from 16 mm to 18 mm.

[0010] In some embodiments, the maximum distance between the interference end and the center plane of the transducing assembly is 18-22 mm, and the center plane of the transducing assembly is parallel to the plane in which the connecting end is located.

[0011] In some embodiments, the ear hook further comprises a deformation member, the flexible member is wrapped on the outer surface of the deformation member, the deformation member comprises a first end and a second end, the first end is connected to the transducing assembly, and the second end is an end of the deformation member close to the interference end, and the deformation member can change the bending angle under the action of force.

[0012] In some embodiments, the flexible member is made of silica gel, and the hardness of the flexible member is 20A-40A; the deformation member is made of memory titanium wire, and the diameter of the deformation member is 0.6-0.8 mm.

When a user uses the earphone provided by the present application, the ear hook is used for hanging the earphone on the back of the user's ear. In the case that the ear hook is used for hanging the earphone on the back of the user's ear, the transducing assembly faces the user's auricle, and the user's tragus is in contact with the first contact surface. Since the first contact surface is a curved surface with curvature, compared with the existing open earphone, the contact area between the user's tragus and the first contact surface is larger, and the pressure on the unit contact area is smaller.

[0033] In order to make the above objectives, features and advantages of the present application more apparent and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application.

[0035] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly specified and limited.

[0036] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" and the like should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited.

Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0038] Compared with traditional closed earphones, open earphones do not need to be worn into the ear. During outdoor activities, a user using an open earphone can hear the sound from the surrounding environment. In the event of an emergency, the user can timely avoid according to the change of the sound from the surrounding environment. However, during the wearing process of the user, the open earphone can cause extrusion to the tragus of the user, thereby reducing the wearing comfort of the user. Therefore, how to solve the problem that the open earphone causes extrusion to the tragus of the user, thereby reducing the wearing comfort of the user, has become a difficult problem that technicians in the field need to solve urgently. In order to solve these problems, the present application provides an earphone 100 (as shown in Figure 1 and an earphone system 1000 (as shown in Figure 9 ).

[0039] Please refer to Figure 1 and Figure 2 , the earphone 100 of the embodiment of the present application comprises a transducing assembly 10 and an ear hook 20, the transducing assembly 10 comprises a first contact surface 11, the first contact surface 11 is a curved surface with an arc, and the ear hook 20 is used for hanging the earphone 100 on the back of the ear of the user. In the case that the ear hook 20 is used for hanging the earphone 100 on the back of the ear of the user, the transducing assembly 10 faces the auricle of the user, and the first contact surface 11 contacts the tragus of the user.

[0040] Specifically, the earphone 100 comprises a transducing assembly 10 and an ear hook 20, wherein the transducing assembly 10 is a part of the earphone 100 responsible for sound conversion (such as a built-in speaker or an external speaker structure), the transducing assembly 10 converts an electrical signal into a sound wave, thereby enabling the user to hear the sound. The ear hook 20 is a structure on the earphone 100 for fixing the earphone 100 on the ear of the user, and the ear hook 20 can ensure that the earphone 100 is stably hung on the back of the ear of the user and is not easy to fall off. During the use of the earphone 100, the user will wear the earphone 100 to carry out various physical activities, and the ear hook 20 can ensure that the earphone 100 will not fall off due to various actions of the head of the user or the action of gravity.

[0041] Specifically, the transducing assembly 10 comprises a first contact surface 11, which is a curved surface with an arc. The surface of the transducing assembly 10 of the earphone 100 (i.e. the first contact surface 11 as mentioned above) is a curved surface with an arc, which makes the first contact surface 11 in a curved shape. This curved shape design can make the whole earphone 100 better fit the user's ear, especially the transducing assembly 10 better fit the user's pinna part, thereby providing the user with a more comfortable wearing effect and better sound quality transmission. The curved shape design of the first contact surface 11 not only helps to improve the adaptability of the earphone 100 in the ear, but also can avoid the earphone 100 from falling off during the user's body movement. In the case that the earphone 100 is hung on the user's ear back, the transducing assembly 10 faces the user's pinna to ensure that the first contact surface 11 contacts the user's tragus. This makes the sound emitting direction of the earphone 100 point to the user's ear canal, rather than to other parts of the user's head. The transducing assembly 10 of the earphone 100 can better transmit sound to the user's ear canal through the contact of the first contact surface 11 with the tragus, while the ear hook 20 can ensure that the earphone 100 will not easily fall off during movement or activity. The first contact surface 11 with the curved surface with an arc can make the earphone 100 better fit the tragus, reduce the user's discomfort when wearing the earphone 100, and improve the sound quality performance of the earphone 100.

[0042] Further, the tragus refers to the soft tissue part outside the ear. Since the tragus usually has an arc, the first contact surface 11 is provided as a curved surface with an arc, and the arc of the curved surface of the first contact surface 11 is set to match the arc of the tragus to maximize the contact area between the first contact surface 11 and the tragus, thereby reducing the pressure on the unit area on the contact part between the first contact surface 11 and the user's tragus, and reducing the pressure of the first contact surface 11 on the user's tragus. Through the fit design between the first contact surface 11 and the user's tragus, the transducing assembly 10 can evenly distribute the pressure applied to the user's tragus, thereby avoiding the user's tragus from having a local excessive pressure concentration, and reducing the user's discomfort when wearing the earphone 100.

[0043] It can be understood that the earphone 100 provided by the application comprises the transducing assembly 10 and the ear hook 20, the transducing assembly 10 comprises the first contact surface 11, the first contact surface 11 is a curved surface with a curvature, when a user uses the earphone 100 provided by the application, the ear hook 20 is used for hanging the earphone 100 on the back of the user's ear, in the case that the ear hook 20 is used for hanging the earphone 100 on the back of the user's ear, the transducing assembly 10 faces the pinna of the user, and the tragus of the user is in contact with the first contact surface 11, because the first contact surface 11 is a curved surface with a curvature, compared with the existing open earphone 100, the contact area between the tragus of the user and the first contact surface 11 is larger, and the pressure on the unit contact area is smaller. Therefore, during the wearing process of the user, the application reduces the degree of extrusion of the earphone 100 on the tragus of the user, and improves the wearing comfort of the user.

[0044] Please refer to Figure 1 、 Figure 2 and Figure 3 In some application embodiments, the radius of the curvature of the first contact surface 11 ranges from 30 mm to 40 mm.

[0045] Specifically, the first contact surface 11 is a curved surface with a curvature, the first contact surface 11 is the part directly in contact with the tragus of the user, and the first contact surface 11 is arranged as a curved surface, which can make the earphone 100 better fit the tragus of the user, thereby improving the comfort of the user during wearing. The radius of the curvature of the first contact surface 11 (i.e. the radius R in Figure 3 ) is arranged to range from 30 mm to 40 mm, thereby ensuring that the shape of the first contact surface 11 is a curved surface that fits the shape of the tragus of the user, which ensures that the earphone 100 can better fit the shape of the ear.

[0046] The radius of the curvature of the first contact surface 11 is arranged to range from 30 mm to 40 mm, please refer to Figure 2 The radius of the curvature mentioned here refers to the radius of curvature of the inner arc surface part of the first contact surface 11. The smaller the radius of curvature, the greater the curvature of the first contact surface 11, and vice versa. For the first contact surface 11, the radius of curvature ranging from 30 mm to 40 mm is moderate, which ensures that the first contact surface 11 will not cause excessive pressure on the tragus of the user due to excessive curvature, nor will it reduce the fitting degree with the tragus of the user due to excessive flatness. The radius of curvature is ergonomically designed and suitable for the shape of the ears of most people.

[0047] Please refer to Figure 1 and Figure 4In some embodiments, the ear hook 20 comprises a flexible piece 21, which comprises a connecting end 211 and an abutting end 212. The connecting end 211 is connected to the transducing assembly 10. The abutting end 212 first extends away from the transducing assembly 10 and then extends towards the transducing assembly 10 in a curved manner.

[0048] In particular, the ear hook 20 is a structure for fixing the earphone 100 to the ear of a user. The ear hook 20 can ensure that the earphone 100 is not easily dropped or moved during wearing. The ear hook 20 comprises a flexible piece 21, which is a part of the ear hook 20 that can be bent or deformed to help the user to complete the wearing operation of the earphone 100. The flexible piece 21 can also provide necessary support for the entire earphone 100. After the user completes the wearing of the earphone 100, the user can also adjust the shape of the flexible piece 21 according to the shape of the user's ear to improve the comfort and stability of the earphone 100.

[0049] More specifically, the flexible piece 21 comprises a connecting end 211 and an abutting end 212. The connecting end 211 of the flexible piece 21 is connected to the transducing assembly 10 of the earphone 100 to ensure that the ear hook 20 is stably fixed in position with the transducing assembly 10. The abutting end 212 of the flexible piece 21 has a specific curved path, i.e., first extends away from the transducing assembly 10 and then extends towards the transducing assembly 10 in a curved manner. The abutting end 212 of the flexible piece 21 initially extends away from the transducing assembly 10. This bending allows the earphone 100 to bypass the external contour of the ear, ensuring that the earphone 100 can be stably hung on the ear. Then, the abutting end 212 of the flexible piece 21 extends towards the transducing assembly 10 in a curved manner to ensure that part of the ear hook 20 can closely fit the back of the ear, making the earphone 100 more stable during wearing, and ensuring that the earphone 100 is less likely to fall or slip. Finally, the abutting end 212 of the flexible piece 21 extends away from the transducing assembly 10 in a curved manner, thereby ensuring that the ear hook 20 can adapt to the shape of the user's ear, increasing the comfort of the user wearing the earphone 100, and further increasing the stability of the earphone 100, so that the earphone 100 is less likely to slip.

[0050] Please refer to Figure 1 and Figure 5 In some embodiments, the first contact surface 11 is provided with a sound outlet hole 112, and the angle between the normal of the plane where the sound outlet hole 112 is located and the plane where the first cross section 213 of the flexible piece 21 is located is 65°-75°.

[0051] It can be understood that the first contact surface 11 is part of the transducing assembly 10, which needs to convert electrical energy into sound waves and release to the user's ear canal. Therefore, the first contact surface 11 is provided with a sound outlet hole 112.

[0052] Specifically, when the user wears the earphone 100, the opening direction of the sound outlet hole 112 needs to be set to align with the ear canal of the user, therefore, the present application sets the included angle between the normal line of the plane where the sound outlet hole 112 is located and the plane where the first section 213 of the flexible piece 21 is located (i.e. the included angle α in Figure 5

[0053] Please refer to Figure 1 and Figure 6 In some application embodiments, the first contact surface 11 is provided with the sound outlet hole 112, and the included angle between the normal line of the plane where the sound outlet hole 112 is located and the plane where the second section 214 of the flexible piece 21 is located is 5°-15°.

[0054] Specifically, the first contact surface 11 is part of the transducing assembly 10, which needs to convert electrical energy into sound waves and release to the ear canal of the user, therefore, the first contact surface 11 is provided with the sound outlet hole 112. When the user wears the earphone 100, the opening direction of the sound outlet hole 112 needs to be set to align with the ear canal of the user, therefore, the present application sets the included angle between the normal line of the plane where the sound outlet hole 112 is located and the plane where the second section 214 of the flexible piece 21 is located (i.e. the included angle β in Figure 6

[0055] Please refer to Figure 1 and Figure 7 In some application embodiments, the maximum distance between the side of the flexible piece 21 close to the connecting end 211 and the transducing assembly 10 is 16-18 mm.

[0056] Specifically, the curved shape of the flexible piece 21 not only helps to improve the comfort of the earphone 100, but also effectively improves the wearing stability of the earphone 100. The multiple bending paths of the flexible piece 21 can help the ear hook 20 better fit different parts of the ear, ensuring that the earphone 100 is not easy to slide or fall off during the user's activities after being worn by the user. The maximum distance between the side of the flexible piece 21 close to the connecting end 211 and the transducing assembly 10 (i.e. the distance d in Figure 7 ​​The line segment d) is set to 16 mm-18 mm. This size design ensures that the headphones 100 can adapt to the ear shape of different users, that is, ensures that the bending path of the flexible part 21 can fit the ear contour of different users, reduce the local pressure of the ear hook 20 in contact with the ear, and avoid the occurrence of a single high pressure point during wearing, which would cause discomfort to the user. This ensures that the headphones 100 are more suitable for long-term wear and use during sports.

[0057] In some implementation methods of the application, please refer to Figure 1 and Figure 7 The maximum distance between the contact end 212 and the center plane 113 of the transducer 10 is 18 mm to 22 mm, and the center plane 113 of the transducer 10 is parallel to the plane 2111 where the connection end is located.

[0058] Specifically, the center plane 113 of the transducer assembly 10 and the plane 2111 where the connection end is located are both as follows: Figure 7 As shown, the curved shape of the flexible component 21 not only helps improve the comfort of the headphones 100, but also effectively improves the wearing stability of the headphones 100. The multiple bending paths of the flexible component 21 help the ear hook 20 better fit different parts of the ear, ensuring that the headphones 100 are not easy to slip or fall off during the user's activities after being worn. The maximum distance between the contact end 212 and the center surface 113 of the transducer assembly 10 (i.e., Figure 7 The line segment D) is 18 mm to 22 mm. This size design ensures that the earphone 100 can adapt to the ear shape of different users, that is, ensures that the bending path of the flexible part 21 can fit the ear contour of different users, reduce the local pressure of the ear hook 20 in contact with the ear, and avoid the occurrence of a single high pressure point during wearing, which would cause discomfort to the user. This ensures that the earphone 100 is more suitable for long-term wear and use during sports.

[0059] In some implementations, please refer to Figure 1 and Figure 8 The ear hook 20 also includes a deformable element 22, and a flexible element 21 covers the outer surface of the deformable element 22. The deformable element 22 includes a first end 221 and a second end 222. The first end 221 is connected to the transducer assembly 10, and the second end 222 is the end of the deformable element 22 that is close to the contact end 212. The deformable element 22 can change the bending angle under the action of force.

[0060] Specifically, the deformation piece 22 is a component capable of changing shape or bending angle under external force. The earphone 100 comprises the deformation piece 22. The flexible piece 21 is wrapped on the outer surface of the deformation piece 22, so that the flexible piece 21 realizes shape change through the deformation piece 22, ensures that the flexible piece 21 can complete the wearing of the earphone 100 through its own deformation, and ensures that the bending path of the flexible piece 21 can fit the contour of the user's ear. The deformation piece 22 comprises a first end 221 and a second end 222, and the first end 221 is connected with the transducing assembly 10. The second end 222 is an end of the deformation piece 22 close to the abutting end 212, that is, close to the part of the ear hook 20 in contact with the ear. This enables the abutting end 212 to bear external force and deform, thereby enabling the ear hook 20 to better fit the ear, that is, to provide a better wearing experience for the user. The deformation piece 22 can change the bending angle under the action of force, and can also restore to the original shape after the external force is removed. This feature is similar to the rebound function of elastic materials, so that the ear hook 20 can still maintain a fixed shape and angle after long-term use, avoiding the situation that the ear hook 20 is deformed or even loses the function due to long-term use of the earphone 100. At the same time, the deformation piece 22 can also ensure that the flexible piece 21 returns to the original state after deformation, thereby continuously generating a proper clamping force on the ear, ensuring that the earphone 100 is stably and comfortably worn.

[0061] In some embodiments, referring to Figure 1 and Figure 8 , the material of the flexible piece 21 is silica gel, and the hardness of the flexible piece 21 is 20A-40A; the material of the deformation piece 22 is memory titanium wire, and the diameter of the deformation piece 22 is 0.6-0.8 mm.

[0062] Specifically, silica gel is a very soft material that can provide users with extremely high comfort, especially for long-term wear. Silica gel can adapt to the curves of the skin, reducing friction and discomfort. Silica gel has good temperature adaptability and can maintain stable performance in high-temperature and low-temperature environments, so the earphone 100 provided by the present application is also suitable for use in various climate conditions. Silica gel is not easy to cause allergies, so the earphone 100 provided by the present application is also suitable for people with sensitive skin and will not cause skin discomfort or allergic reactions. Silica gel has good waterproof performance and is suitable for wearing during sports or outdoor activities, and is easy to clean. Silica gel has good wear resistance and is not easy to age or damage even after long-term use, and using silica gel as the material of the flexible piece 21 can also improve the service life of the earphone 100.

[0063] Specifically, the material of the flexible piece 21 can be liquid silica gel with smaller hardness. In the present application, the hardness of the flexible piece 21 is 20A-40A. Compared with common types of silica gel, the liquid silica gel used in the present application has smaller hardness, thereby ensuring that the part of the ear hook 20 in contact with the user's skin is softer, improving the comfort of the user.

[0064] Specifically, the diameter of the deformation member 22 is set to 0.6-0.8 mm, so as to ensure the strength of the deformation member 22 while ensuring that the deformation member 22 does not have excessive weight, which not only guarantees the durability of the deformation member 22, but also ensures that the earphone is not too heavy to affect the normal wearing of the user. The biggest feature of the memory titanium wire is its shape memory function, that is, under the action of external force, the memory titanium wire will deform, but once the external force is removed, the memory titanium wire will restore to the original shape. This makes the memory titanium wire very suitable for composing structures that need to be repeatedly deformed and restored, such as eyeglass frames or ear hooks 20. The memory titanium wire also has very high strength and durability, is lighter and more solid than ordinary metals, and can withstand a large pressure or impact without being easily deformed or broken. Therefore, the application uses the memory titanium wire as the material of the deformation member 22, which can improve the durability of the deformation member 22 and prolong the service life of the deformation member 22. In addition, the density of the memory titanium wire is low, so the weight of the memory titanium wire is very light, which makes the user feel almost no weight burden from the ear hook 20 after wearing the earphone 100, making the earphone 100 more suitable for long-term wear.

[0065] In summary, the earphone 100 provided by the application includes a transduction assembly 10 and an ear hook 20, the transduction assembly 10 includes a first contact surface 11, which is a curved surface with a curvature. When the user uses the earphone 100 provided by the application, the ear hook 20 is used to hang the earphone 100 on the back of the user's ear. In the case where the ear hook 20 is used to hang the earphone 100 on the back of the user's ear, the transduction assembly 10 faces the user's auricle, and the user's tragus contacts the first contact surface 11. Since the first contact surface 11 is a curved surface with a curvature, compared with the existing open earphone 100, the contact area between the user's tragus and the first contact surface 11 is larger, and the pressure on the unit contact area is smaller. Therefore, during the user's wearing process, the application reduces the degree of extrusion of the earphone 100 on the user's tragus, and improves the wearing comfort of the user.

[0066] In some embodiments, referring to Figure 1 and Figure 9 the application also provides an earphone system 1000, which includes the earphone 100 in any of the above embodiments and a charging box 200. The charging box 200 is used to charge the earphone 100.

[0067] Specifically, the charging box 200 is an important component in the earphone system 1000, and the inside of the charging box 200 includes but is not limited to a lithium battery, a button cell or a lead-acid battery. The charging box 200 provides a convenient power supply channel for the earphone 100.
