[0046] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0047] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of this application. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0048] In conjunction with Figure 1 , the user's ear 500 may include physiological parts such as the external auditory canal 501, the cavum concha 502, the cymba concha 503, the triangular fossa 504, the antihelix 505, the scaphoid 506, the helix 507, and the tragus 508. Although the external auditory canal 501 has a certain depth and extends to the eardrum, for ease of description and in conjunction with Figure 1 , unless otherwise specified, the external auditory canal 501 specifically refers to its entrance away from the eardrum (i.e., the ear canal). Furthermore, physiological parts such as the cavum concha 502, the cymba concha 503, and the triangular fossa 504 have a certain volume and depth; and the cavum concha 502 is directly connected to the external auditory canal 501, which can be simply regarded as the aforementioned ear canal being located at the bottom of the cavum concha 502.

[0049] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ears. In order to facilitate description and reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards, such as GRAS 45BC KEMAR. Therefore, in this application, descriptions such as "the user wears the earphones 100", "the earphones 100 are in a wearing state" and "in a wearing state" may refer to the earphones 100 described in this application being worn on the ears of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences between the earphones 100 worn by different users and the earphones 100 worn on the ears of the aforementioned simulator, but such differences should be tolerated.

[0050] 2 to 5 , the earphone 100 may include a host module 1 and an ear hook 2, and the host module 1 may include a shell assembly 10 and a speaker 13. The ear hook 2 may be hook-shaped, and the earphone 100 may be worn near the external auditory canal of the user's ear through the ear hook 2 but not blocking the external auditory canal. The ear hook 2 may be connected to the shell assembly 10. In the worn state, the shell assembly 10 is located on the front side of the ear, and the ear hook 2 is at least partially located on the back side of the user's ear, so that the earphone 100 can be hung on the ear. Furthermore, the shell assembly 10 may be used to form an accommodating space 101. The speaker 13 may be arranged in the accommodating space 101, and a sound outlet hole is provided on the shell assembly 10 for transmitting the air-conducted sound provided by the speaker 13 to the external auditory canal of the user's ear.

[0051] To facilitate description of the shape of the housing assembly 10, this application defines the housing assembly 10 as having a first direction X and a second direction Y, wherein the first direction X may be orthogonal to the second direction Y (see FIG5 ). The first direction X may refer to the length direction of the housing assembly 10, and the second direction Y may refer to the thickness direction of the housing assembly 10.

[0052] When worn, the housing assembly 10 is stacked in front of the user's ear along the second direction Y. The housing assembly 10 further comprises a first end 102 and a second end 103 disposed opposite each other along the first direction X. In some embodiments, the first end 102 may refer to the portion facing the user's cavum concha 502 during wear, and the second end 103 may refer to the portion further away from the user's cavum concha 502 relative to the first end 102. In some embodiments, the first end 102 may refer to the portion closer to the back of the user's ear during wear, and the second end 103 may refer to the portion further away from the back of the user's ear relative to the first end 102. The portion of the second end 103 may be connected to the ear hook 2 and will be referred to as the connecting end 103 hereinafter, while the first end 102 may also be referred to as the free end 102 hereinafter.

[0053] In some embodiments, the first end 102 of the shell assembly 10 at least partially extends into the cavum conchae 502 of the user's ear, leaving the external auditory canal of the user's ear in an open state. The user's external auditory canal being in an open state means that the shell assembly 10 does not completely seal the external auditory canal, or that the shell assembly 10 does not block the external auditory canal, allowing the external auditory canal to communicate with the external environment. In addition, due to individual differences between different users, when the earphone 100 is worn by different users, the shell assembly 10 may partially block the external auditory canal, but the external auditory canal is still not completely blocked and can still communicate with the external environment.

[0054] In some embodiments, referring to Figures 5, 6, and 7, in the second direction Y, the outer wall surface LS2 of the housing assembly 10 of the movement module 1, which faces the user's ear when worn, is arched away from the user's ear. This arrangement allows the design of the housing assembly 10 to better conform to the shape of the user's ear, reducing the pressure exerted by the housing assembly 10 on the user's ear, particularly the tragus 508. Furthermore, the planar extension direction restriction is removed, facilitating smoother insertion of the first end 102 of the housing assembly 10 into the user's cavum concha 502, thereby improving wearing comfort and stability.

[0055] The structural design of the outer wall surface LS2 of the housing assembly 10, which faces the user's ear when worn, can affect the overall structure of the housing assembly 10 and, in turn, the user's wearing comfort. For example, the structure of the outer wall surface LS2 can affect the position of the first end 102 of the housing assembly 10. If the outer wall surface LS2 causes the housing assembly 10 to extend too short, it may prevent the first end 102 of the housing assembly 10 from easily entering the user's cavum concha 502. Alternatively, when the first end 102 of the housing assembly 10 extends into the user's cavum concha 502, the outer wall surface LS2 may not properly clear the user's tragus 508, resulting in excessive pressure on the user's tragus 508. Similarly, if the outer wall surface LS2 causes the housing assembly 10 to extend too long, it may increase the pressure exerted by the first end 102 on the antihelix 505 and the cavum concha 502, or it may prevent the outer wall surface LS2 from properly clearing the user's tragus 508, resulting in excessive pressure on the user's tragus 508.

[0056] Referring to FIG. 6 , optionally, in the first direction X, the first end 102 has a first reference point C1 that is farthest from the second end 103. In some embodiments, the first reference point C1 may be the point on the first end 102 that is farthest from the second end 103 along the first direction X. In some embodiments, the first reference point C1 may be the point on the first end 102 that is farthest from the second end 103 along a tangent line to the dome of the outer wall LS2. To prevent the arched shape of the outer wall LS2 from causing the portion of the housing assembly 10 closer to the first end 102 to be too short or too long, thereby preventing the first end 102 from properly fitting within the cavum concha 502 and reducing the user's wearing comfort, the distance L10 from the dome G1 of the outer wall LS2 to the first reference point C1 in the first direction X is between 14 mm and 20 mm. The dome G1 of the outer wall LS2 may refer to the point with the deepest depression in the arched region or the point in the arched region that is farthest from the user's ear. The distance from the dome G1 to the first reference point C1 in the first direction X may refer to a projection length in the first direction X of a line connecting the dome G1 and the first reference point C1 .

[0057] Furthermore, to enable the earphone 100 to adapt to the shape of the user's ear, the distance L10 from the dome G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X can be designed more specifically. In some embodiments, if the user has a small ear, to prevent the arched shape of the outer wall surface LS2 from causing the portion of the housing assembly 10 closer to the first end 102 to be too long, thereby compressing the cavum concha 502 of the user's ear, the distance L10 from the dome G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X can be 14 mm to 16 mm. In some embodiments, if the user has a large ear, to prevent the arched shape of the outer wall surface LS2 from causing the portion of the housing assembly 10 closer to the first end 102 to be too short, thereby preventing the first end 102 from properly contacting the cavum concha 502 and causing an unstable fit, the distance L10 from the dome G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X can be 18 mm to 20 mm. Specifically, the distance L10 from the dome G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X may be 14.1 mm, 15.2 mm, 16.5 mm, 17.7 mm, 18.6 mm, or 19.9 mm.

[0058] Optionally, in the second direction Y, the outer wall surface LS2 of the housing assembly 10 facing the user's ear has a second reference point C2 adjacent to the second end 103 and closest to the user's ear when worn. In some embodiments, the second reference point C2 may be the portion of the outer wall surface LS2 near the second end 103, the point farthest from the dome G1 or the decorative cover (described later) in the second direction Y. To prevent the second end 102 from being reliably supported on the user's face when extending into the cavus concha 502, thereby reducing wearing stability, the distance L12 between the second reference point C2 and the first reference point C1 in the first direction X is between 20 mm and 31 mm. Alternatively, the second reference point C2 may be the lowest point of the arched outer wall surface LS2 of the housing assembly 10 facing the user's ear. Optionally, the second reference point C2 is configured to abut the facial skin in front of the tragus 508 of the user's ear when worn.

[0059] Furthermore, to enable the earphone 100 to adapt to the shape of the user's ear, the distance L1 from the second reference point C2 to the first reference point C1 in the first direction X can be designed more specifically. In some embodiments, if the user has a small ear, to prevent the first end 102 from properly abutting the cavum concha 502 when the second reference point C2 rests on the antitragus, the distance L12 from the second reference point C2 to the first reference point C1 in the first direction X can be 20 mm to 24 mm. In some embodiments, if the user has a large ear, to prevent the area where the second reference point C2 rests on the antitragus and excessively compresses the user's antitragus, the distance L12 from the second reference point C2 to the first reference point C1 in the first direction X can be 26 mm to 31 mm. Specifically, the distance L12 from the second reference point C2 to the first reference point C1 in the first direction X can be 21.9 mm, 23.4 mm, 25 mm, 26.4 mm, or 28.02 mm.

[0060] In this case, the earphone 100 can be more stably supported on the facial skin area in front of the user's tragus 508 through the second reference point C2. In addition, when the earphone 100 is supported on the facial skin area in front of the user's tragus 508 through the second reference point C2, the first end 102 can also extend into the concha cavity 502 and is not likely to excessively compress the antihelix 505.

[0061] Optionally, the distance H20 from the arch G1 of the outer wall surface LS2 to the second reference point C2 in the second direction Y is between 1.3 mm and 2.2 mm. Furthermore, in order to enable the earphone 100 to adapt to the shape of the user's ear, the distance H20 from the arch G1 of the outer wall surface LS2 to the second reference point C2 in the second direction Y can be more targeted. Specifically, the distance H20 from the arch G1 of the outer wall surface LS2 to the second reference point C2 in the second direction Y can be 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm or 2.1 mm. In this case, when the earphone 100 is supported on the facial skin area in front of the user's tragus 508 through the second reference point C2, the outer wall surface LS2 is not likely to over-press the user's tragus 508.

[0062] Generally, due to the volume limitation of the cavum concha 502, if the first end 102 is too large or too thick, it may be difficult to extend into the cavum concha 502. If the first end 102 is too small, the internal space is not easy to utilize.

[0063] Optionally, in the second direction Y, the outer wall surface LS2 of the housing assembly 10 on the side facing the user's ear has a third reference point C3 adjacent to the first end 102 and closest to the user's ear when worn. In some embodiments, the third reference point C3 may be the portion of the outer wall surface LS2 close to the first end 102 and the point farthest from the dome G1 in the second direction Y. In some embodiments, the third reference point C3 may also be another lowest point on the arched outer wall surface LS2 on the side facing the user's ear of the housing assembly 10.

[0064] Optionally, the distance L13 from the third reference point C3 to the first reference point C1 in the first direction X is between 3 mm and 5 mm. Furthermore, to allow the earphone 100 to adapt to the shape of the user's ear while increasing the internal space of the housing assembly 10, the distance L13 from the third reference point C3 to the first reference point C1 in the first direction X should be as small as possible without excessively squeezing the cavum concha 502. For example, the distance L13 from the third reference point C3 to the first reference point C1 in the first direction X can be 3 mm to 3.5 mm, 3.51 mm to 4 mm, 4.01 mm to 4.5 mm, or 4.51 mm to 5 mm. For example, the distance L13 from the third reference point C3 to the first reference point C1 in the first direction X can be 3.45 mm, 3.8 mm, 4.29 mm, or 4.53 mm. In this case, the first end 102 of the housing assembly 10 can easily extend into the cavum concha 502, and the internal space is easily utilized (e.g., to facilitate assembly of the speaker 13).

[0065] If the dome G1 of the outer wall LS2 is not recessed enough toward the inside of the housing assembly 10, the outer wall LS2 may excessively press against the tragus 508 when the wearer is wearing the headset. If the dome G1 of the outer wall LS2 is recessed too much toward the inside of the housing assembly 10, the outer wall LS2 and the corresponding inner wall LS1 (described later) of the housing assembly 10 may have excessively large curvatures, which may affect the layout of the various components within the housing assembly 10.

[0066] Optionally, a distance H30 from the dome G1 of the outer wall surface LS2 to the third reference point C3 in the second direction Y is between 2 mm and 3 mm. For example, the distance H30 from the dome G1 of the outer wall surface LS2 to the third reference point C3 in the second direction Y can be 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, or 2.9 mm. In this case, during wear, the outer wall surface LS2 is less likely to excessively compress the tragus 508, and the outer wall surface LS2 of the shell assembly 10 is also prevented from excessively bending.

[0067] In the existing earphones 100, the battery 14 and the speaker 13 are usually located in two separate shells, which also means that a longer wire is required to connect the battery 14 and the speaker 13. During the assembly process of the earphones 100 and the user's use, the wire is often broken due to external force, causing the earphones 100 to be unable to be used normally. At the same time, separating the battery 14 and the speaker 13 into two shells will also increase the size of the earphones 100 and reduce the user's wearing experience.

[0068] In some embodiments, the earphones 100 further include a battery 14, which can power the speaker 13. When worn, because the first end 102 of the housing assembly 10 is closer to the user's external auditory canal than the second end 103, the speaker 13 can be positioned within the housing assembly 10 closer to the first end 102, and the battery 14 can be positioned within the housing assembly 10 closer to the second end 103. In this case, the air-conducted sound generated by the speaker 13 is more easily transmitted to the user's external auditory canal, ensuring a good listening experience.

[0069] In some embodiments, the speaker 13 and the battery 14 can be spaced apart and arranged in the accommodation space 101 formed by the housing assembly 10 along the first direction X. In this case, the speaker 13 and the battery 14 can be assembled in the housing assembly 10 at the same time, thereby improving assembly efficiency, reducing the length of the connecting wires, and making the connecting wires disposed in the housing assembly 10 less susceptible to damage.

[0070] Furthermore, a partition wall 104 may be provided in the accommodation space 101 of the shell assembly 10, see Figure 6. The partition wall 104 may be used to separate the speaker 13 and the battery 14 to prevent the speaker 13 from being damaged in the event of leakage of the battery 14. In some embodiments, the partition wall 104 may be integrally formed with the shell assembly 10, which may improve the consistency of the shell assembly 10. In some embodiments, the partition wall 104 may be formed separately and installed in the shell assembly 10 by snapping, gluing, etc., which may reduce the difficulty of processing the shell assembly 10. Referring to Figures 4 and 5, illustratively, a partition wall 104 adjacent to the dome G1 of the outer wall LS2 is provided on the inner wall surface LS1 of the shell assembly 10 facing the user's ear. The speaker 13 is located in the accommodation space formed by the partition wall 104 and the first end 102, and the battery 14 is located in the accommodation space formed by the partition wall 104 and the second end 103.

[0071] In some embodiments, the speaker 13 has a first axis ZX1 and the battery 14 has a second axis ZX2. The first axis ZX1 and the second axis ZX2 each have a positive direction pointing to the user's ear when worn. In a reference plane defined by the first direction X and the second direction Y, the positive direction of the first axis ZX1 and the projection of the second axis ZX2 in the reference plane are arranged to intersect. In other words, the speaker 13 and the battery 14 are arranged to be tilted relative to each other. Such an arrangement can improve the space utilization of the housing assembly 10 along the first direction X, ensure that the housing assembly 10 can accommodate various electronic components without increasing the volume, and avoid the housing assembly 10 of the earphone 100 being too large, affecting the user's wearing experience. Among them, the first axis ZX1 can be parallel to the vibration direction of the diaphragm of the speaker 13, and pass through the center of gravity of the speaker 13, the geometric center or centroid of its end face (e.g., a circular end face, a runway-shaped end face). The second axis ZX2 can refer to an axis passing through the axis of symmetry of the battery 14, the geometric center or centroid of its two end faces.

[0072] Furthermore, referring to FIG5 , the intersection angle θ between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 projected onto the reference plane is an acute angle. To ensure that the tilt angle between the battery 14 and the speaker 13 is not too large while reducing the size of the housing assembly 10 along the first direction X, thereby preventing the size of the housing assembly 10 in the second direction Y from increasing, the intersection angle θ between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 projected onto the reference plane can be between 10° and 14° or between 11° and 14°. For example, the intersection angle θ can be 10°, 10.5°, 11°, 11.5°, 12°, 12.5°, 13°, 13.5°, or 14°. In some embodiments, the first axis ZX1 and the second axis ZX2 can be parallel to the reference plane. In this case, the angle between the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 can be equal to the above-mentioned intersection angle θ.

[0073] In some embodiments, on a reference plane defined by a first direction X and a second direction Y, the radial dimension of the speaker 13 is greater than the radial dimension of the battery 14, the second direction Y has a positive direction pointing toward the user's ear, and the intersection angle θ1 between the projection of the positive direction of the first axis ZX1 in the reference plane and the positive direction of the second direction Y is greater than the intersection angle θ2 between the projection of the positive direction of the second axis ZX2 in the reference plane and the positive direction of the second direction Y. In some embodiments, the second axis ZX2 can be arranged parallel to the second direction Y, thereby reducing the difficulty of assembling the battery 14. The radial dimension of the speaker 13 can refer to the length of the speaker 13 in a cross section on the reference plane that is perpendicular to the first axis ZX1. The radial dimension of the battery 14 can refer to the length of the speaker 13 in a cross section on the reference plane that is perpendicular to the second axis ZX2.

[0074] In this case, because the radial dimension of the speaker 13 is larger than that of the battery 14, if the speaker 13 and the battery 14 are arranged side by side along the first direction X, the speaker 13 occupies a larger space along the first direction X. Therefore, when the speaker 13 is arranged at an angle relative to the second direction Y, the effect on the degree of change in the projected length of the housing assembly 10 in the first direction X is greater than when the battery 14 is arranged at an angle relative to the second direction Y, thereby facilitating a reduction in the length of the housing assembly 10 in the first direction X.

[0075] The earphone 100 also includes a circuit board 15, which is arranged in the accommodating space 101 formed by the shell assembly 10 and is located on the side away from the user's ear relative to the speaker 13 and the battery 14. In some embodiments, the number of circuit boards 15 can be one, and the wires of the battery 14 and the speaker 15 are connected at the same time for control. The projection of the circuit board 15 along the second direction Y at least partially overlaps with the speaker 13 and the battery 14. Referring to Figure 5, the circuit board 15 can be arranged along the first direction X. Such an arrangement can increase space utilization and reduce production costs while ensuring the performance of the speaker 13 and the battery 14. In some embodiments, the number of circuit boards 15 can be two, which are electrically connected to the battery 14 and the speaker 13 respectively, and the axes of the two circuit boards 15 are parallel to the first axis ZX1 of the speaker 13 and the second axis ZX2 of the battery 14 respectively. Such an arrangement can further reduce the volume of the shell assembly 10.

[0076] In some embodiments, the housing assembly 10 includes a first housing 111 and a second housing 112 that cooperate with each other along the second direction Y. The speaker 13 and the battery 14 can be fixed to the first housing 111. When worn, the first housing 111 is closer to the user's ear than the second housing 112. The circuit board 15 is fixed to the second housing 112. In this case, it can facilitate the assembly and disassembly of the earphone 100. The circuit board 15 can be fixed to the second housing 112 of the housing assembly 10 by hot melting. Specifically, a plurality of hot melting posts can be provided on the second housing 112, and a corresponding plurality of through holes can be provided on the circuit board 15. During assembly, the through holes on the circuit board 15 can be matched with the hot melting posts on the second housing 112, and the circuit board 15 can be fixed to the second housing by hot melting.

[0077] Referring to Figures 5 and 8 , the earphones 100 also include a charging port 16 disposed on the first housing 111 and a magnetic element 17 disposed between the battery 14 and the first housing 111 along the second axis ZX2. Placing the magnetic element 17 between the battery 14 and the first housing 111 fully utilizes the storage space 101, increasing space utilization. In this case, the earphones 100 can be used in conjunction with a charging case 900 that has a magnetic charging function.

[0078] 9 , the charging box 900 may include a lower shell component 910 and an upper shell component 920. The lower shell component 910 may be provided with two contoured grooves 911 for accommodating the earphones 100, respectively, and the upper shell component 920 may cover the lower shell component 910 to close the contoured grooves 911.

[0079] Furthermore, the charging box 900 may include a main control circuit board arranged in the lower shell assembly 910 and electrode terminals 912 arranged on the main control circuit board. Among them, the electrode terminals 912 can be provided in multiple groups as needed, for example, two groups. The electrode terminals 912 can be exposed in the contoured groove 911. When any earphone 100 is placed in the charging box 900, the charging interface 16 in the earphone 100 can be in one-to-one contact with the electrode terminals 912 in the charging box 900 to meet the requirements of charging, detection and other functions. Accordingly, the electrode terminals 912 may include a positive power supply terminal and a negative power supply terminal, and may further include a detection terminal; the lines connecting the two of them may form a triangle, such as an equilateral triangle, or they may be arranged at intervals along a straight line, for example, spaced apart from each other and collinear.

[0080] In addition, the charging box 900 may include a magnetic structure (not shown) disposed within the lower shell assembly 910. The magnetic structure may be provided in multiple groups, for example, two groups, as required. After any earphone 100 is placed in the contoured groove 911, the magnetic structure and the magnetic element 17 within the earphone 100 may form a magnetic pairing, so that the charging port 16 and the electrode terminal 912 are in one-to-one contact.

[0081] When the earphone 100 is in the worn state, the first end 102 of the shell assembly 10 may need to extend into the user's cavum concha 502. Therefore, if the shape of the outer wall surface LS2 of the first end 102 of the shell assembly 10 facing away from the user's ear cannot maintain a good fit with the cavum concha 502, the earphone 100 may increase the user's foreign body sensation during wearing, resulting in a reduced experience.

[0082] In some embodiments, the first direction X extends from the second end 103 toward the first end 102. The outer wall surface LS3 of the housing assembly 10, facing away from the user's ear, may include a first curved transition zone 105. On a reference plane defined by the first direction X and the second direction Y, the first curved transition zone 105 gradually approaches the user's ear along the positive direction of the first direction X, thereby forming a first portion of the first end 102. This approach allows the outer surface of the housing assembly 10 to gradually curve toward the user's ear, thereby better adapting to the shape of the cavum concha 502 and reducing the sensation of a foreign body when worn.

[0083] 7 , the curvature radius of the first arc-shaped transition zone 105 gradually decreases along the positive direction of the first direction X. In this case, the curvature radius of the first arc-shaped transition section away from the user's ear is larger, which can facilitate the arrangement of components inside the housing assembly 10 .

[0084] Considering the tilted arrangement of the speaker 13 and battery 14, if the extension length of the first curved transition zone 105 in the first direction X is too small, it may cause parts of the housing assembly 10 to be larger in the thickness direction, reducing the space utilization within the housing assembly 10. In some embodiments, the extension component L105 of the first curved transition zone 105 along the first direction X is no less than 16 mm. In this case, the thickness of the housing assembly 10 can be kept within a reasonable range at all locations, and the internal space utilization of the housing assembly 10 can also be improved.

[0085] As described above, in the first direction X, the first end 102 has a first reference point C1 that is farthest from the second end 103. The first reference point C1 has been described above and will not be repeated here. At the first reference point C1, the angle α1 between the tangent of the first curved transition zone 105 and the second direction Y can be between 5 and 8 degrees. For example, the angle α1 between the first curved transition zone 105 and the second direction Y at the first reference point C1 is 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, or 8°. In some embodiments, referring to Figures 7 and 10, the first curved transition zone 105 further has a first intermediate reference point C4 that is located at a distance L14 from the first reference point C1 along the first direction X between 1.8 mm and 3 mm. At the first intermediate reference point C4, the angle α2 between the tangent of the first curved transition zone 105 and the second direction Y is between 35° and 53°. In some embodiments, the first arcuate transition zone 105 has a second intermediate reference point C5 6 mm to 9 mm away from the first reference point C1 along the first direction X. An angle α3 between a tangent line of the first arcuate transition zone 105 and the second direction Y is between 60° and 80°.

[0086] As described above, by sequentially limiting the shapes of the first arc-shaped transition zone 105 at the first reference point C1, the first intermediate reference point C4, and the second intermediate reference point C5, the first arc-shaped transition zone 105 can be effectively adapted to the shape of the user's cavum concha 502.

[0087] In some specific embodiments, the distance L14 between the first intermediate reference point C4 and the first reference point C1 in the first direction X is 2.35 mm. At the first intermediate reference point C4, the angle α2 between the tangent line of the first curved transition zone 105 and the second direction Y is 43.91 degrees. The distance L14 between the second intermediate reference point C5 and the first reference point C1 in the first direction X is 7.43 mm. At the second intermediate reference point C5, the angle α3 between the transition line of the first curved transition zone 105 and the second direction Y is 70.8 degrees.

[0088] In some embodiments, in the second direction Y, the side of the housing assembly 10 facing the user's ear has a third reference point C3 adjacent to the first end 102 and closest to the user's ear. The outer wall surface LS2 of the housing assembly 10 facing the user's ear includes a second curved transition zone 106 located between the first reference point C1 and the third reference point C3. The first direction X has a negative direction from the first end 102 to the second end 103. Along the negative direction of the first direction X, the second curved transition zone 106 gradually approaches the user's ear, thereby forming the second portion of the first end 102. Optionally, the radius of curvature of the second curved transition zone 106 gradually increases along the negative direction of the first direction X, gradually approaching the user's ear, thereby forming the second portion of the first end 102.

[0089] Through the above method, the shape of the first end 102 can be made to fit the shape of the interior of the concha cavity more closely, thereby reducing the foreign body sensation when the first end 102 is inserted into the concha cavity 502 and improving the user's wearing experience.

[0090] In some embodiments, a distance L13 from the third reference point C3 to the first reference point C1 in the first direction X is between 3 mm and 6 mm. Optionally, at the third reference point C3, an angle α4 between a tangent line of the second arc-shaped transition zone 106 and the second direction Y is between 75 degrees and 95 degrees.

[0091] In some specific embodiments, a distance L13 from the third reference point C3 to the first reference point C1 in the first direction X is 4.29 mm. At the third reference point C3, an angle α4 between the tangent of the second arc-shaped transition zone 106 and the second direction Y is 84.9°.

[0092] By limiting the projection length between the third reference point C3 and the first reference point C1 in the first direction X, the projection length in the second direction Y, and the slope of the second arc-shaped transition zone 106 therebetween in the above manner, the second arc-shaped transition zone 106 can be better adapted to the interior of the user's cavum concha 502, thereby reducing the foreign body sensation.

[0093] Furthermore, the outer wall surface LS2 of the housing assembly 10, facing the user's ear, includes a third curved transition zone 107 located on the side of the third reference point C3 facing away from the first reference point C1. The third curved transition zone 107 is arranged in an arch shape facing away from the user's ear. In the first direction X, the distance L10 from the top G1 of the third curved transition zone 107 to the first reference point C1 in the first direction X is between 15 mm and 18 mm, and the distance H10 from the first reference point C1 in the second direction Y is between 1 mm and 3 mm.

[0094] In some specific embodiments, the distance L10 from the top G1 of the third curved transition zone 107 to the first reference point C1 in the first direction X is 17.7 mm, and the distance H10 from the first reference point C1 in the second direction Y is 1.91 mm. In this case, when the earphone 100 is worn, the top G1 of the third curved transition zone 107 is approximately located outside the user's tragus 508, thereby reducing the possibility of pressure on the tragus 508.

[0095] As shown in FIG11 , as described above, the host module 1 may include a housing assembly 10. The host module 1 may also include the aforementioned speaker 13 and battery 14.

[0096] Optionally, as shown in FIG11 , the housing assembly 10 may include a shell 11 and a decorative cover 12 . The shell 11 has an outer side that faces away from the user's ear when worn. The decorative cover 12 is disposed on the outer side surface OS1 of the shell 11 and is used to form a touch positioning area 120 for the user to perform touch positioning. The host module 1 may further include a touch module 18 . The touch module 18 may be disposed on the shell 11 and have a touch detection area 182 that at least partially overlaps with the touch positioning area 120 . When a user touches a corresponding area on the decorative cover 12, the touch detection area 182 can detect the user's touch.

[0097] The touch positioning area 120 can be used to locate the touch detection area 182. After the user feels the touch positioning area 120, they can roughly know that they have reached or are close to the area available for touch operation. The touch detection area 182 can detect the user's touch operation. The touch module 18 can detect the user's touch operation through the touch detection area 182, thereby realizing touch sensing, so that the headset 100 can realize human-computer interaction functions with the user. For example, it can realize volume adjustment, power on and off control, song switching, play and pause functions, and can also realize Bluetooth connection and disconnection operations, switch Bluetooth connected devices, and other operations.

[0098] Furthermore, the housing 11 and / or the decorative cover 12 may be provided with a positioning protrusion 121. The positioning protrusion 121 is located within the touch positioning area 120 and protrudes from the outer side surface OS1 of the decorative cover 12 facing away from the housing 11. While the touch positioning area 120 provides single-touch navigation positioning, by arranging the positioning protrusion 121 to protrude from the outer side surface OS1 of the decorative cover 12 facing away from the housing 11, it is convenient for the user to touch the positioning protrusion 121 when touching the housing 11. This allows the positioning protrusion 121 to function as a secondary touch navigation positioning function on the basis of the decorative cover 12, allowing the user to more accurately locate the touch detection area 182 through the positioning protrusion 121, thereby improving the convenience of touch operation. Furthermore, the decorative cover 12 can provide a unique decorative visual effect for the earphones 100. By combining this unique visual effect with the touch detection area 182 (at least partially overlapping), the earphones 100 can be made smaller without the need for a separate touch detection area. The visual effect of the decorative cover 12 can easily let the user know the position of the touch detection area 182, thereby reducing the user's learning cost and improving the convenience of the user's touch operation.

[0099] In some embodiments, as shown in FIG11 , the outer surface OS1 of the housing 11 and the outer surface OS2 of the decorative cover 12 can collectively form the outer surface OS of the host module 1. The outer surface OS of the host module 1 is configured to be arched outward. In other words, the outer surface OS1 of the housing 11 and the outer surface OS2 of the decorative cover 12 are both arched outward. This increases the lateral space utilization of the headset 100, facilitating placement of other components within the housing assembly 10. Furthermore, the outward arched configuration visually minimizes the outer surface OS of the host module 1.

[0100] In some embodiments, as shown in FIG11 , the first direction X and the second direction Y of the housing assembly 10 are also the first direction X and the second direction Y of the housing 11. The housing 11 has a length direction X, a width direction Z, and a thickness direction Y that may be perpendicular to each other. The housing 11 is configured to be positioned over the user's ear along the thickness direction Y when worn. Specifically, the length direction X of the housing 11 may be indicated by the X arrow in FIG11 , the thickness direction Y of the housing 11 may be indicated by the Y arrow in FIG11 , and the width direction Z of the housing 11 may be indicated by the Z arrow in FIG11 , with the directions X, Y, and Z being perpendicular to each other.

[0101] In some embodiments, as shown in FIG12 , the ratio of the dimensions of the decorative cover 12 and the outer shell 11 in the length direction X can be greater than or equal to 0.5 and less than or equal to 0.8. The dimension of the decorative cover 12 in the length direction X can be represented by length D in FIG12 , and the dimension of the outer shell 11 in the length direction X can be represented by length E in FIG12 . Wherein, 0.5 ≤ D / E ≤ 0.8. For example, the ratio of the dimensions of the decorative cover 12 and the outer shell 11 in the length direction X can be 0.6, 0.7, etc. Preferably, the ratio of the dimensions of the decorative cover 12 and the outer shell 11 in the length direction X is greater than or equal to 0.6 and less than or equal to 0.7.

[0102] Optionally, the ratio of the dimensions of the decorative cover 12 and the outer shell 11 in the width direction Z can be greater than or equal to 0.6 and less than or equal to 0.95. The dimension of the decorative cover 12 in the width direction Z can be represented by length F in FIG. 12 , and the dimension of the outer shell 11 in the width direction Z can be represented by length G in FIG. Wherein, 0.6 ≤ F:G ≤ 0.95. For example, the ratio of the dimensions of the decorative cover 12 and the outer shell 11 in the width direction Z can be 0.65, 0.75, etc. Optionally, the ratio of the dimensions of the decorative cover 12 and the outer shell 11 in the width direction Z can be greater than or equal to 0.7 and less than or equal to 0.87.

[0103] By setting the size ratio of the decorative cover 12 to the housing 11 in this way, the decorative cover 12 can occupy a larger proportion of the outer surface OS1 of the housing 11 , so that the user can easily touch the decorative cover 12 when touching the outer surface OS1 of the housing 11 .

[0104] Of course, in other embodiments, the size ratio of the decorative cover 12 and the outer shell 11 can also be other size ratios. For example, the size ratio of the decorative cover 12 and the outer shell 11 in the length direction X can also be greater than or equal to 0.3 and less than or equal to 0.8, and the size ratio of the decorative cover 12 and the outer shell 11 in the width direction Z can be greater than or equal to 0.4 and less than or equal to 0.9. This embodiment will not be listed one by one in detail here.

[0105] In some embodiments, as shown in FIG12 , the positioning protrusion 121 may be arranged in a strip shape, with the extension direction H of the positioning protrusion 121 intersecting both the length direction X and the width direction Z. The extension direction H of the positioning protrusion 121 may be indicated by the arrow H in FIG12 . This arrangement enables the user's hand to touch the positioning protrusion, which intersects the length direction X and the width direction Z, to provide the user with a clear tactile sensation, thereby facilitating the user's touch positioning and providing the user with more obvious secondary touch navigation positioning.

[0106] Optionally, the extension direction H of the positioning protrusion 121 is not parallel to the length direction X and the width direction Z of the housing 11, and can intersect with the length direction X of the housing 11 to form an acute angle. The angle α between the extension direction H of the positioning protrusion 121 and the length direction X of the housing 11 is shown in Figure 12.

[0107] Optionally, the angle between the extension direction H of the positioning protrusion 121 and the longitudinal direction X of the housing 11 can be 30° to 70°. For example, the angle between the extension direction H of the positioning protrusion 121 and the longitudinal direction X of the housing 11 can be 40°, 50°, 60°, etc. This arrangement makes it easier for the user to touch and identify the positioning protrusion 121.

[0108] In some embodiments, as shown in Figures 12 and 14, the housing 11 may have a connecting end 103 (also referred to as the second end 103 in some descriptions herein) connected to the ear hook 2 and a free end 102 (also referred to as the first end 102 in some descriptions) facing away from the connecting end 103 in the length direction X. The housing 11 may be bent in the thickness direction Y in the direction of the outer side surface OS1 of the housing 11. The bending in the direction of the outer side surface OS of the housing 11 causes the free end 102 to be closer to the ear hole of the user's ear than the connecting end 103, and the decorative cover 12 to be closer to the connecting end 103. Because the free end 102 is closer to the ear when the earphone 100 is worn on the ear, and the connecting end 103 connected to the ear hook 2 is farther away from the ear, arranging the decorative cover 12 closer to the connecting end 103 makes it easier for the user to touch the decorative cover 12.

[0109] In some embodiments, as shown in Figures 13 and 14 , the housing 11 can be bent in the thickness direction Y toward the outer surface OS1 of the housing 11 , such that the free end 102 is closer to the user's ear opening than the connection end 103. This arrangement allows the decorative cover 12 to be positioned as much as possible parallel to the sagittal plane of the human body when the earphones 100 are worn, minimizing the area of ​​the curved surface of the decorative cover 12 extending toward the ear opening. This facilitates blind operation by the user and allows for quick positioning of the positioning protrusion 121.

[0110] In some embodiments, as shown in FIG13 , the free end 102 may have a first reference position K1 that is farthest from the connecting end 103 in the length direction X, and the decorative cover 12 may have a second reference position K2 that is closest to the first reference position K1 in the length direction X. The free end 102 may at least partially extend into the concha cavity 502 in the worn state.

[0111] The housing 11 has a curved transition zone 114 between a first reference position K1 and a second reference position K2. From the second reference position K2 to the first reference position K1, the curved transition zone 114 gradually approaches the user's ear along the thickness direction Y when worn. Therefore, when the earphone 100 is worn, the portion of the earphone 100 corresponding to the curved transition zone 114 gradually approaches the user's ear along the thickness direction Y, even fitting snugly against the ear. This facilitates better insertion of the free end 102 into the cavum concha 502, enhancing wearing comfort and stability. Furthermore, the curved transition zone 114 begins at the second reference position K2 of the decorative cover 12 and gradually slopes toward the first reference position K1, with the second reference position K2 serving as a turning point. This allows the user to more effectively locate the decorative cover 12, and thus the touch positioning area 120, improving touch control convenience. The edge of the decorative cover 12 is located near the turning point of the curved housing 11, making it easier for the user to identify and locate the decorative cover 12 when operating blindly.

[0112] In some embodiments, the roughness of the outer surface OS2 of the decorative cover 12 can be greater than the roughness of the outer surface OS1 of the outer shell 11. This allows the user to feel a difference in tactile sensation when touching the decorative cover 12 and the outer surface OS1 of the outer shell 11, making it easier for the user to distinguish between the decorative cover 12 and the outer shell 11. This further facilitates the user's positioning of the touch detection area 182 for touch control, thereby improving touch control convenience.

[0113] In some embodiments, the color of the outer surface OS2 of the decorative cover 12 is different from the color of the outer surface OS1 of the outer shell 11. For example, the color of the outer surface OS2 of the decorative cover 12 can be red, blue, etc., and the color of the outer surface OS1 of the outer shell 11 can be white, black, etc., so that the user can distinguish the decorative cover 12 from the outer shell 11 in appearance. By setting the color of the outer surface OS2 of the decorative cover 12 to be different from the color of the outer surface OS1 of the outer shell 11, a color difference can be created on the outer surface OS of the host module 1, thereby visually reducing the size of the entire host module 1, thereby improving the visual effect of the headset 100 and visually miniaturizing it. Moreover, the color difference of the decorative cover 12 can be clearly located in the touch detection area 182, allowing the user to easily know the location of the touch detection area 182, reducing learning costs and improving touch efficiency.

[0114] In some embodiments, the material of the decorative cover 12 can be different from that of the outer shell 11. For example, the decorative cover 12 can be made of a transparent acrylic sheet, while the outer shell 11 can be made of metal. Alternatively, the decorative cover 12 can be made of metal, while the outer shell 11 can be made of plastic, resin, or other materials. The different materials of the decorative cover 12 and outer shell 11 can also make it easier for users to distinguish between the decorative cover 12 and the outer shell 11. Furthermore, the different materials can enhance the decorative effect of the decorative cover 12 and provide users with a differentiated touch texture, thereby facilitating touch operations and improving touch convenience.

[0115] In some embodiments, as shown in FIG14 , at least a portion of the edge of the decorative cover 12 can be exposed on the outer side surface OS1 of the housing 11 to enclose a touch positioning area 120. The touch positioning area 120 can be formed by at least a portion of the edge of the decorative cover 12 exposed on the outer side surface OS1 of the housing 11. When a user touches the outer side surface OS1 of the housing 11, they can feel at least a portion of the edge of the decorative cover 12. The presence of the edge provides a tactile sensation, allowing the user to clearly know that they have touched the corresponding area, effectively facilitating navigation and positioning.

[0116] Optionally, the edge of the decorative cover 12 can be arranged in a ring shape and completely exposed on the outer side surface OS1 of the outer shell 11, thereby enclosing a touch positioning area 120. The edge of the decorative cover 12 surrounds the positioning protrusion 121. In other words, the edge of the decorative cover 12 is completely exposed on the outer side surface OS1 of the outer shell 11, allowing the user to touch the entire edge of the decorative cover 12, which improves the positioning effect and further enhances the user's touch efficiency. In addition, the positioning protrusion 121 is arranged in the middle of the decorative cover 12 and is not close to the edge of the decorative cover 12. This arrangement can ensure that the position of the positioning protrusion 121 is more stable and is less likely to fall off the decorative cover 12 enclosed to form the touch positioning area 120.

[0117] In some embodiments, as shown in FIG. 14 , the housing 11 may be provided with a positioning groove 113 on the outer side thereof, and the decorative cover 12 is received in the positioning groove 113 through the notch of the positioning groove 113 .

[0118] Optionally, the shapes and sizes of the positioning groove 113 and the decorative cover 12 can match each other, so as to facilitate the assembly of the decorative cover 12 into the positioning groove 113 of the housing 11 and make the joint between the two more uniform, providing a more delicate and soft touch.

[0119] Optionally, the seam between the edge of the decorative cover 12 and the edge of the notch of the positioning groove 113 is exposed on the outer side, and the seam surrounds the positioning protrusion 121. The seam formed between the edge of the decorative cover 12 and the edge of the positioning groove 113 can provide a tactile sensation that is clearly different from other locations. When a user touches the seam, they can quickly and effectively know that they have touched the corresponding area, which can improve the user's touch efficiency.

[0120] In some embodiments, a positioning protrusion 121 can be provided protruding from the outer side surface OS1 of the housing 11. The decorative cover 12 defines a positioning hole 122, through which the positioning protrusion 121 is inserted. The positioning hole 122 and the positioning protrusion 121 enable precise assembly of the decorative cover 12 and the outer side surface OS1 of the housing 11, allowing for more accurate positioning of the touch detection area 182. Furthermore, the coordination of the positioning groove 113 and the positioning protrusion 121 further enhances the assembly precision between the decorative cover 12 and the housing 11, allowing for more precise positioning of the touch detection area 182 by the touch positioning area 120, thereby improving touch accuracy and convenience.

[0121] Optionally, the positioning protrusion 121 can be protruded from the outer surface OS2 of the decorative cover 12 and be integrally formed with the decorative cover 12. This can make the positioning protrusion 121 more stable and not easy to detach from the decorative cover 12. Moreover, the position between the positioning protrusion 121 and the touch positioning area 120 is relatively fixed, which can provide users with accurate one-touch navigation positioning and two-touch navigation positioning.

[0122] Optionally, the outer side surface OS of the host module 1 may have at least two sound pickup holes 115. The two sound pickup holes 115 may be located on two opposite slopes of the outer side surface OS of the host module 1. Placing the two sound pickup holes 115 on opposite slopes allows them to point in different directions, thereby expanding the sound pickup range of the earphone 100. Furthermore, pointing in different directions reduces interference between the two sound pickup holes 115.

[0123] In some embodiments, the positioning protrusion 121 may be arranged in a strip shape, and the two sound pickup holes 115 are respectively located on both sides of the positioning protrusion 121. In this way, the two sound pickup holes 115 are arranged on both sides of the positioning protrusion 121, which can reduce the mutual interference between the two sound pickup holes 115.

[0124] The positional relationship between the touch detection area 182 and the positioning protrusion 121 can be in various forms.

[0125] Method 1: Optionally, the touch detection area 182 may surround the positioning protrusion 121, so that the user can touch the positioning protrusion 121 to accurately locate and confirm the position of the touch detection area 182, so that the user can quickly and accurately locate the position of the touch detection area 182 when using the headset 100, thereby optimizing the user experience.

[0126] Method 2: The touch detection area 182 can be closer to the connection end 103 than the positioning protrusion 121 to facilitate the user to sense and trigger the touch detection area 182. Alternatively, the touch detection area 182 can surround the positioning protrusion 121 so that the user can accurately locate the touch detection area 182 through the positioning protrusion 121 and trigger the touch module 18.

[0127] In some embodiments, as shown in Figures 15 and 16, the touch module 18 may include a touch metal pattern 181 and a circuit board 15. The circuit board 15 may be arranged inside the housing 11. The touch metal pattern 181 may be arranged inside the housing 11 or sandwiched between the decorative cover 12 and the housing 11. The touch metal pattern 181 is electrically connected to the circuit board 15. The touch metal pattern 181 is used to form a touch detection area 182.

[0128] When the user touches and / or presses the touch positioning area 120 or the positioning protrusion 121, it can trigger the sensing to form the touch metal pattern 181 of the touch detection area 182. The touch metal pattern 181 can thereby generate a corresponding signal and transmit the corresponding signal to the circuit board 15 to further trigger responses of other functions.

[0129] In some embodiments, the touch metal pattern 181 can also be configured as a radio frequency antenna for the headset 100. The headset 100 can receive and transmit RF (Radio Frequency) signals through the touch metal pattern 181, thereby expanding and enriching the functions of the headset 100 and facilitating information interaction between the headset 100 and other devices.

[0130] Of course, there can be at least one sound pickup hole 115. Sound pickup hole 115 extends through at least the housing 11, connecting the external environment and the accommodating space 101. Accordingly, the host module 1 may also include a microphone 19. Microphone 19 is disposed within the accommodating space 101 and corresponding to sound pickup hole 115, thereby picking up sound from the external environment through sound pickup hole 115.

[0131] Optionally, as shown in Figures 17 to 20, the host module 1 may be provided with at least two sound pickup holes 115 connecting the accommodating space 101 and the external environment. The host module 1 may also include at least two microphones 19, and the at least two microphones 19 are arranged at intervals in the accommodating space 101, corresponding to the at least two sound pickup holes 115. Taking the two microphones 19 as an example, one of the sound pickup holes 115 may pass through the outer shell 11 and be located on the periphery of the decorative cover 12. The other sound pickup hole 115 may pass through the outer shell 11 and the decorative cover 12, that is, the sound pickup hole 115 is located within the range surrounded by the edge of the decorative cover 12. Accordingly, two microphones 19 may be provided in the accommodating space 101, corresponding to the two sound pickup holes 115 one by one.

[0132] By providing at least two sound pickup holes 115, the sound pickup range can be expanded and the sound pickup quality can be improved. Moreover, one of the holes is provided on the decorative cover 12 and the other is provided on the decorative cover 12, which can reduce the probability of blocking both holes when touching the decorative cover 12, thereby reducing the impact on the sound pickup effect.

[0133] Optionally, taking the two sound pickup holes 115 as an example, the distance between the two sound pickup holes 115 is greater than or equal to the dimension of the decorative cover 12 along the arrangement direction of the two microphones 19. Since one sound pickup hole 115 is disposed outside the decorative cover 12, this arrangement allows the other sound pickup hole 115 to be located as close to the edge of the decorative cover 12 as possible, thereby increasing the distance between the two sound pickup holes 115. When touching the touch positioning area 120 of the decorative cover 12, it is unlikely that the sound pickup hole 115 located outside the decorative cover 12 will be blocked, nor will it be likely that the sound pickup hole 115 located near the edge of the decorative cover 12 will be blocked. This further reduces the probability of simultaneously blocking both sound pickup holes 115 when touching the decorative cover 12, thereby minimizing the impact on the sound pickup effect.

[0134] 17 , the touch positioning area 120 is located between the two sound pickup holes 115. In this way, when the touch positioning area 120 is touched, the two sound pickup holes 115 are not easily blocked, thereby reducing the impact on the sound pickup effect.

[0135] Optionally, the arrangement direction of the two sound pickup holes 115 intersects with the length direction X and the width direction Z of the housing 11. The sound pickup hole 115 that passes through the decorative cover 12 (that is, the sound pickup hole 115 located within the edge of the decorative cover 12) is closer to the connection end 103 and closer to the edge of the decorative cover 12 away from the ear hook 2 in the width direction Z than the sound pickup hole 115 located on the periphery of the decorative cover 12. The sound pickup hole 115 is arranged to the "lower left". On the one hand, it can make the sound pickup hole 115 that passes through the decorative cover 12 closer to the user's mouth and the speaker 13, and can clearly pick up the sound of the user's speech and the sound of the speaker 13, facilitate noise reduction processing, and improve the quality of sound pickup of the external environment. On the other hand, the sound pickup hole 115 is closer to the edge of the decorative cover 12 away from the ear hook 2 in the width direction Z, which can reduce the probability of blocking the sound pickup hole 115 when touching the decorative cover 12.

[0136] Optionally, as shown in Figures 18 to 20, the main module 1 may further include a sealing component 190, at least a portion of which is arranged between the housing 11 and the microphone 19, for isolating the sound pickup path from the accommodating space 101, so that the sound pickup path is sealed relative to the portion of the space outside the sound pickup path of the accommodating space 101, thereby reducing the impact of dust, water vapor, etc. entering the sound pickup path through the sound pickup hole 115 on other electrical components in the accommodating space 101.

[0137] Optionally, the host module 1 may further include a fixing plate for fixing the microphone 19. Optionally, the fixing plate may be the circuit board 15. Alternatively, in other embodiments, the fixing plate may be a plate-like structure other than the circuit board 15, or may be part of the housing assembly 10, and may be used to fix the microphone 19 and further fix other components.

[0138] As shown in Figures 18-20, a fixing plate is housed within accommodating space 101 and defines a through-hole 151. Microphone 19 is secured to one side of the fixing plate, covering through-hole 151. At least a portion of sealing assembly 190 is disposed within accommodating space 101, abutting between housing 11 and the side of the fixing plate facing away from microphone 19, thereby connecting through-hole 151 with sound pickup hole 115. This arrangement improves the installation stability and sealing performance of sealing assembly 190.

[0139] There are various matching structures between the sealing component 190 and the housing 11, etc., which can be used for microphones 19 with different installation structures or different positions.

[0140] In some embodiments, for the sound pickup hole 115 that passes through the housing 11 and is located on the periphery of the decorative cover 12, the structure of the sealing assembly 190 and the related description are as follows:

[0141] As shown in Figures 18 and 19, the microphone 19 can pass through the housing 11 and be located outside the decorative cover 12. The sealing assembly 190 can include a sealing rubber ring 191a and a gauze assembly 192a, which are stacked and both disposed in the accommodating space 101 and between the fixing plate and the housing 11. Since the microphone 19 is located on the periphery of the decorative cover 12 and passes through the outer shell 11, in this case, the integrity and unity of the outer shell 11 here are good, so the sealing rubber ring 191a and the gauze assembly 192a are stacked and located between the fixed plate and the outer shell 11. On the one hand, the sealing effect can be better achieved by relying on the outer shell 11 with good integrity. On the other hand, the stacking of the sealing rubber ring 191a and the gauze assembly 192a can achieve a thicker sealing assembly 190, which can be more tightly sealed between the outer shell 11 and the fixed plate. The gauze assembly 192a can also reduce the entry of dust, impurities, etc. into the accommodating space 101, further improving the sealing effect.

[0142] Optionally, sealing rubber ring 191a is stacked on the fixed plate, closer to through-hole 151 than gauze assembly 192a. Gauze assembly 192a is located between sealing rubber ring 191a and housing 11, closer to sound pickup hole 115 than sealing rubber ring 191a. This arrangement, positioning gauze assembly 192a in front of sealing rubber ring 191a (i.e., closer to sound pickup hole 115), can reduce the ingress and accumulation of dust, impurities, etc. on sealing rubber ring 191a, thereby preventing dust, impurities, moisture, etc. from entering accommodating space 101 as early as possible.

[0143] In other embodiments, for the sound pickup hole 115 that passes through the housing 11 and the decorative cover 12, the structure of the sealing assembly 190 and related description examples are as follows:

[0144] As shown in Figure 20, the microphone 19 can pass through the housing 11 and the decorative cover 12, and the sealing assembly 190 can include a sealing rubber ring 191b and at least one mesh assembly 192b. The sealing rubber ring 191b is arranged in the accommodating space 101 and between the housing 11 and the fixed plate, and directly abuts the housing 11 and the fixed plate. At least one mesh assembly 192b is arranged between the housing 11 and the decorative cover 12. Since the fit between the decorative cover 12 and the housing 11 and the fit between the sealing assembly 190 and the fixed plate are prone to accumulate large errors, connecting the sealing rubber ring 191b with stronger deformation ability to the fixed plate can reduce the fit error between the decorative cover 12 and the housing 11 and between the sealing assembly 190 and the fixed plate, thereby ensuring the sealing effect of the circuit accessories.

[0145] Optionally, the number of at least one mesh assembly 192b can be two, one mesh assembly 192b is arranged between the outer shell 11 and the decorative cover 12, and the other mesh assembly 192b and the sealing rubber ring 191b are stacked in the accommodating space 101 and located between the outer shell 11 and the fixed plate.

[0146] By placing mesh assembly 192b between housing 11 and decorative cover 12, the entry of dust, impurities, and moisture into accommodating space 101 is significantly reduced. Furthermore, mesh assembly 192b seals sound pickup hole 115 between housing 11 and decorative cover 12, reducing the ingress of moisture from the sound pickup hole into the space between housing 11 and decorative cover 12, which could affect the stability of the connection between the two. By placing sealing rubber ring 191b within accommodating space 101 and sealing it between housing 11 and the fixing plate, the sealing effect is further enhanced, reducing the leakage of moisture and other substances entering through sound pickup hole 115 into accommodating space 101 and adversely affecting other electrical components therein.

[0147] For the above-mentioned gauze components 192a and 192b, the structures thereof are described as follows:

[0148] As shown in Figures 19 and 20, the gauze mesh assemblies 192a and 192b include an annular double-sided tape 1921 and a gauze mesh 1922. The annular double-sided tape 1921 is stacked with the gauze mesh 1922 and adheres the gauze mesh 1922. Specifically, one side of the annular double-sided tape 1921 can be adhered to the gauze mesh 1922, and the other side can be connected to the housing 11 or the decorative cover 12 to which it is close. For example, for the sound pickup hole 115 that passes through the housing 11 and the decorative cover 12, one side of the annular double-sided tape 1921 can be adhered to the gauze mesh 1922, and the other side can be adhered to the housing 11. For the sound pickup hole 115 that passes through the housing 11 and is located on the periphery of the decorative cover 12, one side of the annular double-sided tape 1921 can be adhered to the gauze mesh 1922, and the other side can be adhered to the housing 11. The gauze 1922 can be arranged opposite to the sound pickup hole 115 and the through hole 151 to effectively reduce the entry of impurities, dust, etc. into the accommodating space 101. Specifically, the annular double-sided tape 1921 surrounds the periphery of the sound pickup hole 115, and the part of the gauze 1922 located in the middle of the annular double-sided tape 1921 is arranged opposite to the sound pickup hole 115.

[0149] Optionally, the number of the annular double-sided tape 1921 is two layers, and the number of the gauze 1922 is one layer, and the gauze 1922 is laminated and bonded between the two layers of annular double-sided tape 1921. By providing two layers of annular double-sided tape 1921, the bonding strength of the gauze 1922 can be enhanced, the gauze 1922 can be better fixed, and the thickness can also be increased, thereby enabling a tighter seal between the housing 11 and the decorative cover 12, or between the housing 11 and the sealing rubber rings 191a, 191b, thereby improving the sealing effect.

[0150] Optionally, the number of annular double-sided adhesive tape 1921 is two layers, the number of gauze 1922 is two layers, the two layers of annular double-sided adhesive tape 1921 are spaced apart, one layer of gauze 1922 is laminated and bonded between the two layers of annular double-sided adhesive tape 1921, and one layer of annular double-sided adhesive tape 1921 is laminated between the two layers of gauze 1922. By providing two layers of gauze 1922, the filtering and blocking effects can be further enhanced. In addition, the provision of two layers of annular double-sided adhesive tape 1921 can effectively fix the double layers of gauze 1922 and further increase the thickness, thereby enabling a tighter seal between the housing 11 and the decorative cover 12, or between the housing 11 and the sealing rubber rings 191a, 191b, thereby improving the sealing effect.

[0151] In conjunction with Figures 21 to 23, the above content has mentioned that the earphone 100 may include a shell assembly 10 and a speaker 13. Optionally, the earphone 100 may also include a sealant (not marked). The shell assembly 10 is used to form a first accommodating cavity 1011. The speaker 13 includes a basin 131 and a metal pad 132. In conjunction with Figures 24 and 25, the basin 131 is arranged in the first accommodating cavity 1011, and the metal pad 132 is arranged on the basin 131 and faces the side of the battery 14 to ensure that the speaker 13 is electrically connected to other components. The sealant is used to seal the gap between the outer peripheral wall of the basin 131 and the inner peripheral wall of the first accommodating cavity 1011.

[0152] By setting a sealant to seal the gap between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011, the speaker 13 and the shell can be sealed, thereby improving the sealing of the shell assembly 10 and reducing the risk of water ingress and damage to electronic components.

[0153] During the process of dispensing the sealant, it is often necessary to dispense the sealant around the frame 131 so that the sealant is continuously filled between the outer peripheral wall of the frame 131 and the inner peripheral wall of the first accommodating cavity 1011, thereby achieving a stable and reliable sealing effect between the outer peripheral wall of the frame 131 and the inner peripheral wall of the first accommodating cavity 1011. In the prior art, the metal pad 132 is often configured to extend from the frame 131 to the outside of the inner peripheral wall of the first accommodating cavity 1011 to connect to a power source outside the first accommodating cavity 1011. During the dispensing process, the pad will form a large obstruction to the gap between the outer peripheral wall of the frame 131 and the inner peripheral wall of the first accommodating cavity 1011, making it inconvenient to dispense the sealant near the pad. There is a risk of the sealant being interrupted at the pad, which reduces the sealing reliability.

[0154] By setting the metal pad 132 to be located on the side of the inner wall of the first accommodating cavity 1011 facing the battery 14, and setting the metal pad 132 to maintain a certain distance from the inner wall of the first accommodating cavity 1011, the gap between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011 can be exposed to the outside world at the pad during the dispensing process, thereby facilitating dispensing at the pad, and facilitating the continuous filling of the sealant between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011, so as to achieve a stable and reliable sealing effect.

[0155] Furthermore, the wire 133 can extend from the metal pad 132 to the inner wall of the first accommodating cavity 1011. The diameter of the wire 133 is much smaller than the size of the metal pad 132. The wire 133 blocks less of the gap between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011, which is conducive to dispensing and achieving a stable and reliable sealing effect.

[0156] 23 to 25 , in some embodiments, the metal pad 132 is disposed so as not to extend beyond the outer peripheral wall of the frame 131 .

[0157] Such a configuration ensures that during the dispensing process, the metal pad 132 will not block the gap between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011, which facilitates the dispensing operation and is conducive to achieving a stable and reliable sealing effect.

[0158] In combination with Figures 23, 24 and 26, in some embodiments, the metal pad 132 is configured to extend beyond the outer wall of the basin frame 131, and the distance S1 of the metal pad 132 extending beyond the outer wall of the basin frame 131 is not greater than half of the gap size S2 between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011.

[0159] Such a configuration ensures that during the glue dispensing process, the metal pad 132 will not completely block the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011, and glue dispensing can still be performed at the metal pad 132. By setting the protruding distance S1 of the metal pad 132 relative to the outer peripheral wall of the basin frame 131 to be no greater than half the gap size S2 between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011, during the glue dispensing process, the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011 can be partially exposed to the outside world at the pad. Since the sealant has a certain fluidity during glue dispensing, the fluidity of the sealant can be utilized to fully fill the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011, thereby achieving a stable and reliable sealing effect. For example, the protruding distance S1 of the metal pad 132 relative to the outer peripheral wall of the basin frame 131 can be set to 0.2 to 0.3 times, or 0.4 to 0.5 times, the gap size S2 between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011.

[0160] In some embodiments, in combination with Figures 23, 27 and 28, the first accommodating cavity 1011 has an open end 1014, the basin 131 is placed in the first accommodating cavity 1011 from the open end 1014, the metal pad 132 is located on the side of the basin 131 facing the open end 1014, and the earphone 100 also includes a wire 133, which is welded to the side of the metal pad 132 facing the open end 1014.

[0161] During the assembly process of the basin frame 131, the peripheral side of the basin frame 131 and the side of the basin frame 131 facing away from the opening end 1014 will come into contact with the inner wall of the first accommodating cavity 1011. By setting the metal pad 132 on the side of the basin frame 131 facing the opening end 1014, and welding the wire 133 to the side of the metal pad 132 facing the opening end 1014, the interference of the metal pad 132 and the wire 133 on the assembly process can be reduced, thereby improving the assembly efficiency.

[0162] 23 to 25 , in some embodiments, the sealant is applied from the side of the open end 1014 to the gap between the outer circumferential wall of the basin frame 131 and the inner circumferential wall of the first accommodating cavity 1011 .

[0163] During the dispensing process, the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011 can be exposed to the outside through the open end 1014, thereby facilitating dispensing of glue from the outside through the open end 1014 into the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011, so that the sealant enters the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011 from the side of the open end 1014. This arrangement facilitates the dispensing operation and improves assembly efficiency.

[0164] In combination with Figures 27 to 29, in some embodiments, the earphone 100 also includes a bracket 134, the basin 131 is provided with an annular table 1311 facing the open end 1014 and an assembly table 1312, the annular table 1311 is arranged along the circumference of the basin 131 and is provided with a first notch 1313, the assembly table 1312 corresponds to the position of the first notch 1313 along the circumference of the basin 131, the metal pad 132 is provided on the assembly table 1312, and the bracket 134 is supported on the annular table 1311.

[0165] Assembly table 1312 can be recessed relative to annular table 1311 at first notch 1313, away from open end 1014. Metal pad 132 often has a certain height. By providing first notch 1313 in annular table 1311, bracket 134 can be supported on annular table 1311 without passing through metal pad 132 and wire 133, facilitating assembly of bracket 134 and frame 131 and improving assembly efficiency.

[0166] In some embodiments, referring to FIG. 28 and FIG. 29 , a second notch 1341 is provided at one end of the bracket 134 facing the basin frame 131 , and the second notch 1341 corresponds to a position of the assembly table 1312 along the circumference of the basin frame 131 .

[0167] By providing the second notch 1341 , the bracket 134 can more easily avoid the metal pad 132 and the wire 133 when supported on the annular table 1311 , thereby facilitating the assembly of the bracket 134 and the basin frame 131 and improving assembly efficiency.

[0168] In some embodiments, in combination with Figures 22 to 24, the shell assembly 10 further forms a second accommodating cavity 1012, and the shell assembly 10 includes a partition wall 104 for separating the first accommodating cavity 1011 and the second accommodating cavity 1012. The earphone 100 also includes a battery 14, which is arranged in the second accommodating cavity 1012, and the metal pad 132 is located on the side of the basin 131 facing the partition wall 104.

[0169] Part of the inner circumferential wall of the first accommodating chamber 1011 may be formed by a partition wall 104, and a portion of the sealant may seal the gap between the outer circumferential wall of the basin frame 131 and the partition wall 104. The provision of the partition wall 104 reduces the risk of water flowing from the side of the speaker 13 near the sound outlet 1013 to the second accommodating chamber 1012.

[0170] The battery 14 can serve as a power source for the speaker 13. The adjacent arrangement of the first and second accommodating cavities 1011 and 1012 simplifies the connection between the battery 14 and the speaker 13. By placing the metal pad 132 on the side of the frame 131 facing the partition wall 104, the distance between the battery 14 and the metal pad 132 can be reduced, further simplifying the connection between the battery 14 and the speaker 13. Furthermore, the metal pad 132 can be connected to the battery 14 via a wire 133, allowing the battery 14 to power the speaker 13.

[0171] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
