[0077] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0078] As a tool for storing and charging Bluetooth earphones, the earphone case usually contains a battery for charging. The earphone case needs to provide space for the battery installation and earphone storage. Therefore, how to reduce the size of the earphone case becomes a problem that needs to be solved.

[0079] Regarding the above situation, firstly, please refer to [link / reference needed]. Figures 1-4 This application proposes an earphone case 100, including a housing 10 and a battery 20. The housing 10 includes an upper shell 11 and a lower shell assembly (not shown separately in the figure) that are movably connected. The lower shell assembly includes a middle shell 12 and a bottom shell 13. When the housing 10 is closed, the upper shell 11, the middle shell 12 and the bottom shell 13 are arranged along a first direction Y. A first receiving space 14 for accommodating earphones 30 is formed between the upper shell 11 and the middle shell 12. The middle shell 12 and the bottom shell 13 are connected to form a second receiving space 15. The battery 20 is disposed in the second receiving space 15 and is used to charge the earphones 30.

[0080] Taking the headphone case 100 placed flat on a table as an example, with the bottom shell 13 in contact with the table, the first direction Y is the vertical direction perpendicular to the table. Therefore, the first direction Y can also be the height direction of the headphone case 100. Figure 3 As shown, on a plane parallel to the first direction Y, the orthographic projection of the first receiving space 14 and the orthographic projection of the second receiving space 15 are at least partially located on the same horizontal plane, which is perpendicular to the first direction Y. The upper shell 11 can be movably connected to the middle shell 12; or, the upper shell 11 can be movably connected to the bottom shell 13; or, the upper shell 11 can be movably connected to both the middle shell 12 and the bottom shell 13. The position and method of the movable connection can be set according to the actual situation, and are not specifically limited here.

[0081] It is understandable that the plane parallel to the first direction Y is a vertical plane. On the vertical plane, the orthographic projection of the first accommodating space 14 and the orthographic projection of the second accommodating space 15 are partially at the same height. That is, the orthographic projections of the first accommodating space 14 and the second accommodating space 15 can overlap. This can reduce the height of the headphone box 100 in the first direction Y, make full use of the height space of the headphone box 100, and make the structure of the headphone box 100 more compact in the first direction Y, reduce space waste, and reduce the volume of the headphone box 100.

[0082] Or, such as Figure 4 As shown, on a plane perpendicular to the first direction Y, the orthographic projection of the first accommodating space 14 and the orthographic projection of the second accommodating space 15 at least partially overlap.

[0083] Similarly, it can be understood that the plane perpendicular to the first direction Y is a horizontal plane. On the horizontal plane, the orthographic projection of the first accommodating space 14 and the orthographic projection of the second accommodating space 15 at least partially overlap. This can reduce the length of the headphone box 100 in the horizontal direction, make full use of the length space of the headphone box 100, and make the structure of the headphone box 100 more compact in the horizontal direction, reduce space waste, and reduce the volume of the headphone box 100.

[0084] Specifically, in this embodiment of the application, by optimizing the spatial layout of the earphone case 100, the projections of the first accommodating space 14 for storing the earphone 30 and the second accommodating space 15 for storing the case battery 20 in the vertical and horizontal directions can at least partially overlap, thereby effectively improving the space utilization of the earphone case 100 and achieving the goal of reducing the volume of the earphone case 100 while ensuring the storage and charging functions of the earphone 30.

[0085] Please see Figure 3 In some embodiments of this application, on a plane parallel to the first direction Y, the orthographic projection of the first accommodating space 14 and the orthographic projection of the second accommodating space 15 are at least partially located on the same horizontal plane. The projection portion of the first accommodating space 14 and the second accommodating space 15 located on the same horizontal plane is a first equal height portion, and the maximum height of the first equal height portion along the first direction Y is H1; wherein, the maximum height of the shell 10 along the first direction Y is H2, and the ratio of H1 to H2 ranges from 0.01 to 0.9.

[0086] Specifically, the maximum height of the shell 10 along the first direction Y is a fixed value H2. The larger the maximum height H2 of the first equal-height portion along the first direction Y, the larger the ratio of H1 to H2, and the more equal-height portions the first accommodating space 14 and the second accommodating space 15 have. That is, the greater the height range in which the orthographic projections of the first accommodating space 14 and the second accommodating space 15 can overlap on the vertical plane, thereby reducing the waste of space in the vertical direction of the headphone box 100, making the overall structure of the headphone box 100 flatter and improving space utilization.

[0087] Similarly, in some embodiments, such as Figure 4 As shown, on a plane perpendicular to the first direction Y, the orthographic projection of the first accommodating space 14 and the orthographic projection of the second accommodating space 15 at least partially overlap. The overlapping portion of the orthographic projection of the first accommodating space 14 and the orthographic projection of the second accommodating space 15 is the first overlapping portion. The maximum length of the first overlapping portion along the second direction X is L1, and the second direction X is perpendicular to the first direction Y. The maximum length of the shell 10 along the second direction X is L2. The ratio of L1 to L2 is in the range of 0.01 to 0.9, and the ratio of L1 to L2 is preferably 0.45.

[0088] Specifically, the maximum length of the shell 10 along the second direction X is a fixed value L2. The larger the maximum length L1 of the first overlapping part along the second direction X, the larger the ratio of L1 to L2, and the more overlapping parts of the orthographic projection of the first accommodating space 14 and the second accommodating space 15. This can reduce the length of the headphone case 100 in the horizontal direction, making the overall structure of the headphone case 100 narrower, further improving space utilization and optimizing portability.

[0089] Please see Figure 3 and Figure 5 In some embodiments of this application, the earphone 30 includes a sound-emitting part 31, and the first receiving space 14 includes a first subspace 141 for accommodating the sound-emitting part 31. On a plane parallel to the first direction Y, the orthographic projection of the first subspace 141 and the orthographic projection of the second receiving space 15 are at least partially located on the same horizontal plane. It can be understood that on a vertical plane, the orthographic projection of the first subspace 141 and the orthographic projection of the second receiving space 15 are partially at the same height, that is, a portion of the orthographic projection of the first subspace 141 and the orthographic projection of the second receiving space 15 can overlap. This can reduce the height of the earphone case 100 in the first direction Y, making full use of the height space of the earphone case 100, that is, making the structure of the earphone case 100 more compact in the first direction Y, reducing space waste, and reducing the volume of the earphone case 100.

[0090] Similarly, in some embodiments, such as Figures 3-5 As shown, on a plane perpendicular to the first direction Y, the orthographic projection of the first subspace 141 at least partially coincides with the orthographic projection of the second accommodating space 15. It can be understood that, on a horizontal plane, the orthographic projection of the first subspace 141 at least partially coincides with the orthographic projection of the second accommodating space 15, thereby reducing the horizontal length of the headphone case 100, making full use of the length space of the headphone case 100, and thus making the structure of the headphone case 100 more compact in the horizontal direction, reducing space waste and decreasing the volume of the headphone case 100.

[0091] Furthermore, in some embodiments of this application, such as Figures 3-4 As shown, on a plane parallel to the first direction Y, the maximum height of the orthographic projection of the second accommodating space 15 along the first direction Y is H3. The projection portion of the orthographic projection of the first subspace 141 and the orthographic projection of the second accommodating space 15 located on the same horizontal plane is the second equal height portion. The maximum height of the second equal height portion along the first direction Y is H4. The ratio of H4 to H3 ranges from 0.03 to 0.7.

[0092] Specifically, the maximum height of the orthographic projection of the second accommodating space 15 along the first direction Y is a fixed value H3. The larger the maximum height H4 of the second equal-height portion along the first direction Y, the larger the ratio of H4 to H3. The more equal-height portions the first subspace 141 and the second accommodating space 15 have, that is, the greater the height range in which the orthographic projections of the first subspace 141 and the second accommodating space 15 can overlap on the vertical plane, thereby reducing the space wastage of the headphone box 100 in the vertical direction, making the overall structure of the headphone box 100 flatter and improving space utilization.

[0093] Similarly, in some embodiments, such as Figures 3-4 As shown, on a plane perpendicular to the first direction Y, the maximum length of the orthographic projection of the second accommodating space 15 along the second direction X is L3. The overlapping portion of the orthographic projection of the first subspace 141 and the orthographic projection of the second accommodating space 15 is the second overlapping portion. The maximum length of the second overlapping portion along the second direction X is L4. The ratio of L4 to L3 is in the range of 0.01 to 0.2, and the ratio of H4 to H3 is preferably 0.15.

[0094] Specifically, the maximum length of the orthographic projection of the second accommodating space 15 along the second direction X is a fixed value L3. The larger the maximum length L4 of the second overlapping part along the second direction X, the larger the ratio of L4 to L3, and the more the orthographic projections of the first subspace 141 and the second accommodating space 15 overlap. This reduces the length of the headphone case 100 in the horizontal direction, making the overall structure of the headphone case 100 narrower, further improving space utilization and optimizing portability.

[0095] Please see Figures 3-5 In some embodiments of this application, the earphone 30 includes a connected sound-emitting part 31 and an ear hook 32; the first receiving space 14 includes a second subspace 142 for receiving the ear hook 32; on a plane parallel to the first direction Y, the orthographic projection of the second subspace 142 and the orthographic projection of the second receiving space 15 are at least partially located on the same horizontal plane. It is understood that on a vertical plane, the orthographic projection of the second subspace 142 and the orthographic projection of the second receiving space 15 are partially at the same height, that is, a portion of the orthographic projection of the second subspace 142 and the orthographic projection of the second receiving space 15 can overlap. This reduces the height of the earphone case 100 in the first direction Y, fully utilizing the height space of the earphone case 100, making the structure of the earphone case 100 more compact in the first direction Y, reducing space waste, and reducing the volume of the earphone case 100. The battery in the earphone 30 is disposed in the sound-emitting part 31.

[0096] Similarly, in some embodiments, such as Figures 3-4As shown, on a plane perpendicular to the first direction Y, the orthographic projection of the second subspace 142 at least partially coincides with the orthographic projection of the second accommodating space 15. It can be understood that, on a horizontal plane, the orthographic projection of the second subspace 142 at least partially coincides with the orthographic projection of the second accommodating space 15, thereby reducing the horizontal length of the headphone case 100, making full use of the length space of the headphone case 100, and thus making the structure of the headphone case 100 more compact in the horizontal direction, reducing space waste and decreasing the volume of the headphone case 100.

[0097] Furthermore, in some embodiments of this application, such as Figure 3 As shown, on a plane parallel to the first direction Y, the maximum height of the orthographic projection of the second accommodating space 15 along the first direction Y is H3. The projection portion of the orthographic projection of the second subspace 142 and the orthographic projection of the second accommodating space 15 located on the same horizontal plane is the third equal-height portion, and the maximum height of the third equal-height portion along the first direction Y is H5. The ratio of H5 to H3 ranges from 0.02 to 0.7, and the ratio of H5 to H3 is preferably 0.25.

[0098] Specifically, the maximum height of the orthographic projection of the second accommodating space 15 along the first direction Y is a fixed value H3. The larger the maximum height H5 of the third equal-height portion along the first direction Y, the larger the ratio of H5 to H3. The more equal-height portions the second subspace 142 and the second accommodating space 15 have, that is, the greater the height range in which the orthographic projections of the second subspace 142 and the second accommodating space 15 can overlap on the vertical plane, thereby reducing the waste of space in the vertical direction of the headphone box 100, making the overall structure of the headphone box 100 flatter and improving space utilization.

[0099] Similarly, in some embodiments, such as Figures 3-4 As shown, on a plane perpendicular to the first direction Y, the maximum length of the orthographic projection of the second accommodating space 15 along the second direction X is L3, and the overlapping part of the orthographic projection of the second subspace 142 and the orthographic projection of the second accommodating space 15 is the third overlapping part, and the maximum length of the third overlapping part along the second direction X is L5; wherein, the ratio of L5 to L3 is in the range of 0.6 to 0.8, and the ratio of L5 to L3 is preferably 0.68.

[0100] Specifically, the maximum length of the orthographic projection of the second accommodating space 15 along the second direction X is a fixed value L3. The larger the maximum length L5 of the third overlapping part along the second direction X, the larger the ratio of L5 to L3, and the more the orthographic projections of the second subspace 142 and the second accommodating space 15 overlap. This reduces the length of the headphone case 100 in the horizontal direction, making the overall structure of the headphone case 100 narrower, further improving space utilization and optimizing portability.

[0101] Please see Figures 3-5 In some embodiments of this application, the earphone 30 includes a sound-emitting part 31, an ear hook 32, and a battery part 33 connected in sequence; the first accommodating space 14 includes a third subspace 143 for accommodating the battery part 33; on a plane parallel to the first direction Y, the orthographic projection of the third subspace 143 and the orthographic projection of the second accommodating space 15 are at least partially located on the same horizontal plane. It can be understood that on a vertical plane, the orthographic projection of the third subspace 143 and the orthographic projection of the second accommodating space 15 are partially at the same height, that is, a portion of the orthographic projection of the third subspace 143 and the orthographic projection of the second accommodating space 15 can overlap, thereby reducing the height of the earphone case 100 in the first direction Y, making full use of the height space of the earphone case 100, that is, making the structure of the earphone case 100 more compact in the first direction Y, reducing space waste, and reducing the volume of the earphone case 100.

[0102] Similarly, in some embodiments, such as Figures 3-4 As shown, on a plane perpendicular to the first direction Y, the orthographic projection of the third subspace 143 at least partially coincides with the orthographic projection of the second accommodating space 15. It can be understood that, on a horizontal plane, the orthographic projection of the third subspace 143 at least partially coincides with the orthographic projection of the second accommodating space 15, thereby reducing the horizontal length of the headphone case 100, making full use of the length space of the headphone case 100, and thus making the structure of the headphone case 100 more compact in the horizontal direction, reducing space waste and decreasing the volume of the headphone case 100.

[0103] Furthermore, in some embodiments of this application, such as Figure 3 As shown, on a plane parallel to the first direction Y, the maximum height of the orthographic projection of the second accommodating space 15 along the first direction Y is H3. The projection portion of the orthographic projection of the third subspace 143 and the orthographic projection of the second accommodating space 15 located on the same horizontal plane is the fourth equal-height portion, and the maximum height of the fourth equal-height portion along the first direction Y is H6. The ratio of H6 to H3 ranges from 0.25 to 0.7, and the ratio of H6 to H3 is preferably 0.32.

[0104] Specifically, the maximum height of the orthographic projection of the second accommodating space 15 along the first direction Y is a fixed value H3. The larger the maximum height H6 of the fourth equal-height portion along the first direction Y, the larger the ratio of H6 to H3. The more equal-height portions the third subspace 143 and the second accommodating space 15 have, that is, the greater the height range in which the orthographic projections of the third subspace 143 and the second accommodating space 15 can overlap on the vertical plane, thereby reducing the waste of space in the vertical direction of the headphone box 100, making the overall structure of the headphone box 100 flatter and improving space utilization.

[0105] Similarly, in some embodiments, such as Figures 3-4 As shown, on a plane perpendicular to the first direction Y, the maximum length of the orthographic projection of the second accommodating space 15 along the second direction X is L3, and the overlapping part of the orthographic projection of the third subspace 143 and the orthographic projection of the second accommodating space 15 is the fourth overlapping part, and the maximum length of the fourth overlapping part along the second direction X is L6; wherein, the ratio of L6 to L3 is in the range of 0.3 to 0.4, and the ratio of L6 to L3 is preferably 0.35.

[0106] Specifically, the maximum length of the orthographic projection of the second accommodating space 15 along the second direction X is a fixed value L3. The larger the maximum length L6 of the fourth overlapping part along the second direction X, the larger the ratio of L6 to L3, and the more the orthographic projection of the third subspace 143 overlaps with that of the second accommodating space 15. This reduces the length of the headphone case 100 in the horizontal direction, making the overall structure of the headphone case 100 narrower, further improving space utilization and optimizing portability.

[0107] In some embodiments of this application, the battery housing 20 can be a single unit, and the shape of the battery housing 20 corresponds to the shape of the second accommodating space 15, so that the battery housing 20 fills the second accommodating space 15. In order to ensure that the battery housing 20 fully fills the second accommodating space 15, the battery housing 20 can be configured with an irregular shape, thereby facilitating the full utilization of the second accommodating space 15.

[0108] Alternatively, in some embodiments, the housing battery 20 may also include a plurality of sub-batteries, which are filled in the second receiving space 15.

[0109] It is easy to understand that the second accommodating space 15 is located below the first accommodating space 14. The first accommodating space 14 is used to accommodate the earphone 30. Therefore, the outline of the first accommodating space 14 can be similar to the shape of the earphone 30. The second accommodating space 15 can utilize the empty area below the first accommodating space 14 so that multiple sub-batteries can be embedded in each space. The second accommodating space 15 has multiple sub-spaces with different shapes. In order to make full use of the empty area below the first accommodating space 14, a sub-battery of a corresponding shape can be set in each sub-space to fully fill the second accommodating space 15. This makes the structure of the earphone case 100 more compact and smaller in size.

[0110] Please see Figure 1 and Figure 5In some embodiments of this application, the middle shell 12 is provided with a first contoured groove 121 and a second contoured groove 122 for accommodating two earphones 30. The first contoured groove 121 and the second contoured groove 122 are located in the first accommodating space 14. The first contoured groove 121 and the second contoured groove 122 are at least partially intersecting, so that when the two earphones 30 are stored, at least a portion of the orthographic projection of the two earphones 30 along the first direction Y overlaps.

[0111] It is easy to understand that the arrangement of the first contouring groove 121 and the second contouring groove 122 allows the two earphones 30 to operate independently without interfering with each other when stored, ensuring their stability. The first contouring groove 121 and the second contouring groove 122 can be arranged along the second direction X. When stored, at least a portion of the left and right earphones 30 are placed vertically overlapping each other to reduce the horizontal space occupied by the earphones 30 in the earphone case 100, thereby further reducing the horizontal length of the earphone case 100 and making it more compact and refined. In some embodiments, the depths of the two contouring grooves can be different, so that when the two earphones 30 are stored in the two contouring grooves respectively, the placement heights of the two earphones 30 are different, facilitating partial overlap of the two earphones 30.

[0112] Furthermore, in some embodiments of this application, the earphone 30 includes a connected sound-emitting part 31 and an ear hook 32; the first contoured groove 121 and the second contoured groove 122 have the same shape, and both the first contoured groove 121 and the second contoured groove 122 have a communicating first receiving groove 123 and a communicating second receiving groove 124. The first receiving groove 123 is used to receive the sound-emitting part 31, and the second receiving groove 124 is used to receive the ear hook 32. The second receiving groove 123 in the first contoured groove 121 is communicating with the second receiving groove 124 in the second contoured groove 122. The battery in the earphone 30 can be integrated into the sound-emitting part 31, thereby allowing both the battery and the sound-emitting part 31 in the earphone 30 to be received in the first receiving groove 123.

[0113] Alternatively, in some embodiments, please refer to Figure 5 The earphone 30 also includes a battery section 33 connected to the ear hook 32. The first contoured groove 121 and the second contoured groove 122 also have a third receiving groove 125 communicating with the second receiving groove 124. The third receiving groove 125 is used to receive the battery section 33. The battery section 33 is set separately, that is, the battery section 33 and the sound-emitting section 31 are not integrated into one piece.

[0114] Specifically, each part of the earphone 30 is provided with a corresponding receiving slot, so that the earphone 30 can be precisely matched with each slot when stored, ensuring that each component is placed stably, reducing shaking and wear, further improving the utilization efficiency of the internal space of the earphone case 100, and making the overall design more compact and reasonable.

[0115] Furthermore, both the first receiving groove 123 and the third receiving groove 125 are provided with magnetic elements 16 (such as...). Figure 2 As shown, the magnetic component 16 is used to attract the sound-generating part 31 and the battery part 33, ensuring that all parts of the earphone 30 fit tightly during storage and preventing damage caused by shaking. At the same time, the magnetic attraction design simplifies the operation of taking the earphone 30 out and putting it in, improving the user experience.

[0116] In some embodiments, the sound-emitting part 31 includes a connected sound-emitting body and a sound outlet. The sound-emitting body is located in a first receiving groove 123. The first receiving groove 123 is provided with a recess for accommodating the sound outlet. When the earphone 30 is placed, the sound outlet is embedded in the recess, ensuring that the sound outlet and the recess fit tightly, preventing shaking and friction, further protecting the earphone 30 components, extending its service life, and keeping the inside of the earphone case 100 neat and orderly.

[0117] Furthermore, such as Figures 5-6 As shown, when the earphone 30 is stored in the first receiving space 14, the height of the sound-emitting part 31 along the direction perpendicular to the bottom wall of the first receiving groove 123 is H7; a limiting ridge 123 is provided on the side of the middle shell 12 facing the upper shell 11, the limiting ridge 123 surrounds part of the periphery of the first receiving groove 123, the height of the limiting ridge 123 along the direction perpendicular to the bottom wall of the first receiving groove 123 is H8, the ratio of H8 to H7 is in the range of 0.2 to 0.7, and the ratio of H8 to H7 is preferably 0.4.

[0118] Specifically, the limiting ridge 123 provides additional support and fixation for the sound-emitting part 31, ensuring that the sound-emitting part 31 will not shift due to vibration when stored, further enhancing the stability of the earphone 30. Meanwhile, the larger the ratio of H8 to H7, the more significant the fixing effect of the limiting ridge 123 on the sound-emitting part 31. If the ratio of H8 to H7 exceeds 0.5, the height of the limiting ridge 123 may be too high, resulting in a small gap between the sound-emitting part 31 and the limiting ridge 123, which could make it inconvenient to remove the earphone 30 from the earphone case 100, affecting the user experience. Therefore, a reasonable setting of the ratio of H8 to H7 ensures both the stability of the earphone 30 and ease of operation.

[0119] In some embodiments, such as Figure 5As shown, the ear hook 32 includes a first section 321 connected to the sound-emitting part 31 and a second section 322 connected to the battery part 33; the second receiving groove 124 has a first part 1241 communicating with the first receiving groove 123 and a second part 1242 communicating with the third receiving groove 125. The first part 1241 is used to receive the first section 321 and the second part 1242 is used to receive the second section 322; wherein, the groove depth of the first receiving groove 123 is h1, the groove depth of the first part 1241 is h2, the groove depth of the second part 1242 is h3, and the groove depth of the third receiving groove 125 is h4, h4 > h2 > h1 > h3.

[0120] Understandably, different depths of receiving grooves are designed for different parts of the earphone 30 to ensure precise matching of each part and to allow the earphone 30 to fit more fully in the contoured grooves, preventing parts from shaking or being damaged due to mismatched groove depths, and further improving the stability and safety of the earphone 30 when stored.

[0121] In some embodiments, the bottom wall of the first receiving groove 123 is inclined, and a connecting pin for charging or transmitting data to the earphone is provided in the first receiving groove 123. The connecting pin is perpendicular to the bottom wall of the first receiving groove 123.

[0122] For example, the first receiving slot 123 has a first slot bottom wall for supporting the earphone 30. The first slot bottom wall is inclined so that the earphone 30 is in an inclined position when stored. Compared with the earphone 30 being laid flat, in this embodiment the earphone 30 is placed at an incline. The orthographic projection area of ​​the inclined earphone 30 on the horizontal plane is smaller than the orthographic projection area of ​​the earphone 30 laid flat on the horizontal plane. This makes full use of the space of the earphone case 100, reduces the length of the earphone case 100 in the horizontal direction, and makes the overall structure of the earphone case 100 more compact, reducing the volume of the earphone case 100. At the same time, a connecting pin is provided on the first slot bottom wall. Since the first slot bottom wall is inclined, the connecting pin is also inclined on the first slot bottom wall.

[0123] In some embodiments, the maximum height of the orthographic projection of the first accommodating space 14 on a plane parallel to the first direction Y is H9, where H9 satisfies: 15.4mm ≤ H9 ≤ 17.6mm. Specifically, when the housing 10 is closed, the first accommodating space 14 is located between the upper shell 11 and the middle shell 12, ensuring that the earphone 30 is completely contained within the housing 10 when stored and is not squeezed by the housing 10. When the upper shell 11 is opened, the first accommodating space 14 is fully exposed, allowing the user to easily remove the earphone 30.

[0124] Secondly, please see Figure 7This application also provides an earphone 30 assembly 200, including two earphones 30 and an earphone case 100 as described in any of the above embodiments, wherein both earphones 30 are accommodated in a first accommodating space 14.

[0125] In some embodiments of this application, the earphone 30 includes a sound-emitting part 31, an ear hook 32, and a battery part 33 connected in sequence (e.g., ...). Figure 5 As shown, the sound-generating part 31 has a first side facing away from the concha cavity. The ear hook 32 includes a first section 321, a middle section, and a second section 322 connected in sequence. The first section 321 is connected to the sound-generating part 31, and the second section 322 is connected to the battery part 33. The first side and the extension direction of the middle section are set at an angle α, where α satisfies: 5°≤α≤30°; and / or, the first side and the extension direction of the first section 321 are set at an angle β, where β satisfies: 35°≤β≤55°. It is easy to understand that the setting of angles α and β is used to optimize the fit between the earphone 30 and the concha cavity, reduce the discomfort of wearing the earphone 30, and ensure the stability of the earphone 30 during exercise.

[0126] Furthermore, in some embodiments of this application, the second segment 322 is connected to the battery section 33 by an arc-shaped transition section. When the earphone 30 is stored, the ear hooks 32 of the two earphones 30 can be stacked. When the two battery sections 33 are close to each other, the arc-shaped transition section can reduce the contact between the battery sections 33 of the two earphones 30, making it less likely for interference to occur between the two battery sections 33.
