[0045] The present application is 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, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0046] Reference to "embodiment" 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 explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0047] Combination Figure 1 The user's ear 500 may include an external auditory canal 501, a concha 502, a cymba 503, a triangular fossa 504, an antihelix 505, a scaphoid 506, a helix 507, and a tragus 508. Although the external auditory canal 501 has a certain depth and extends to the eardrum, for the sake of convenience, and in combination with Figure 1 In the present application, unless otherwise specified, the external auditory canal 501 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity 502, the hymena conchae 503, the triangular fossa 504 and other physiological parts have a certain volume and depth; and the concha cavity 502 is directly connected to the external auditory canal 501, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity 502.

[0048] Furthermore, different users may have individual differences, resulting in different shapes, sizes and other dimensional differences in the ears. For the convenience of description, and to reduce (or even eliminate) individual differences between different users, a simulator containing a head and its (left and right) ears, such as GRAS 45BC KEMAR, can be made based on ANSI: S3.36, S3.25 and IEC: 60318-7 standards. Therefore, in the present application, descriptions such as "the user wears the earphone 100", "the earphone 100 is in a wearing state" and "in a wearing state" may refer to the earphone 100 described in the present application being worn on the ear of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences between the earphone 100 worn by different users and the earphone 100 worn on the ear of the aforementioned simulator, but such differences should be tolerated.

[0049] See also Figures 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 through the ear hook 2 near the external auditory canal of the user's ear but not blocking the external auditory canal. The ear hook 2 may be connected to the shell assembly 10. In the wearing 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. Further, 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 opened 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.

[0050] For the convenience of describing the shape of the housing assembly 10, the present application defines that the housing assembly 10 has a first direction X and a second direction Y, wherein the first direction X may be orthogonal to the second direction Y (see Figure 5). 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 .

[0051] In the wearing state, the shell assembly 10 is overlapped on the front side of the user's ear along the second direction Y. The shell assembly 10 further has a first end 102 and a second end 103 arranged opposite to each other along the first direction X. In some embodiments, the first end 102 may refer to a portion facing the user's cavum concha 502 during wearing, and the second end 103 may refer to a portion farther away from the user's cavum concha 502 relative to the first end 102. In some embodiments, the first end 102 may refer to a portion closer to the back side of the user's ear during wearing, and the second section 103 may refer to a portion farther away from the back side of the user's ear relative to the first end 102. A portion of the second end 103 may be connected to the ear hook 2, which may be referred to as the connecting end 103 hereinafter, and the first end 102 may also be referred to as the free end 102 hereinafter.

[0052] In some embodiments, the first end 102 of the shell assembly 10 at least partially extends into the concha cavity 502 of the user's ear, and the external auditory canal of the user's ear is in an open state. The user's external auditory canal is in an open state means that the shell assembly 10 does not completely close the external auditory canal, or the shell assembly 10 does not block the external auditory canal, so that the external auditory canal can be connected to the external environment. In addition, due to individual differences among 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 be connected to the external environment.

[0053] In some embodiments, see Figure 5 , Figure 6 and Figure 7 In the second direction Y, the outer wall surface LS2 of the shell assembly 10 of the movement module 1 facing the user's ear in the wearing state is arranged in an arch shape away from the user's ear. Through the above manner, the design of the shell assembly 10 can be more closely fitted to the shape of the user's ear, reducing the pressure of the shell assembly 10 on the user's ear, especially on the tragus 508. In addition, the restriction on the extension direction of the plane can also be removed, which is conducive to the first end 102 of the shell assembly 10 extending more smoothly into the user's concha cavity 502, thereby improving the wearing comfort and stability.

[0054] The structural design of the outer wall surface LS2 of the shell assembly 10 facing the user's ear in the wearing state will affect the structure of the entire shell assembly 10, and further affect the wearing comfort of the user. For example, the structure of the outer wall surface LS2 will affect the position of the first end 102 of the shell assembly 10. If the setting of the outer wall surface LS2 causes the shell assembly 10 to extend too short, it may cause the first end 102 of the shell assembly 10 to be difficult to extend into the user's cavum concha 502, or it may cause the first end 102 of the shell assembly 10 to extend into the user's cavum concha 502, and the outer wall surface LS2 may not be able to avoid the user's tragus 508 well, thereby causing excessive pressure on the user's tragus 508. Similarly, if the setting of the outer wall surface LS2 causes the shell assembly 10 to extend too long, it may increase the pressure of the first end 102 on the antihelix 505 and the cavum concha 502, or it may cause the outer wall surface LS2 to be unable to avoid the user's tragus 508 well, thereby causing excessive pressure on the user's tragus 508.

[0055] See also Figure 6 , optionally, in the first direction X, the first end 102 has a first reference point C1 farthest from the second end 103. In some embodiments, the first reference point C1 may be a point of the first end 102 farthest from the second end 103 along the first direction X. In some embodiments, the first reference point C1 may be a point of the first end 102 farthest from the second end 103 along the tangent direction of the arch of the outer wall surface LS2. In order to avoid the arch setting of the outer wall surface LS2 causing the part of the shell assembly 10 closer to the first end 102 to be too short or too long, so that the first end 102 cannot better cooperate with the cavum concha 502, thereby reducing the wearing comfort of the user, the distance L10 from the arch G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X is between 14 mm and 20 mm. Among them, the arch G1 of the outer wall surface LS2 may refer to the point with the deepest depression in the arch area or the point farthest from the user's ear in the arch area. 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 .

[0056] Further, in order to enable the earphone 100 to adapt to the ear shape of the user, the design of the distance L10 from the arch G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X can be more targeted. In some embodiments, when the user's ear is small, in order to avoid the arch setting of the outer wall surface LS2 causing the portion of the shell assembly 10 closer to the first end 102 to be too long, thereby causing pressure on the concha cavity 502 of the user's ear, the distance L10 from the arch G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X can be 14mm-16mm. In some embodiments, when the user's ear is large, in order to avoid the arch setting of the outer wall surface LS2 causing the portion of the shell assembly 10 closer to the first end 102 to be too short, thereby causing the first end 102 to fail to abut the concha cavity 502 well, thereby causing the problem of unstable wearing, the distance L10 from the arch G1 of the outer wall surface LS2 to the first reference point C1 in the first direction X can be 18mm-20mm. 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.

[0057] Optionally, in the second direction Y, the outer wall surface LS2 of the shell 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 in the wearing state. In some embodiments, the second reference point C2 may be a portion of the outer wall surface LS2 close to the second end 103, and the point farthest from the dome G1 or the decorative cover (described later) in the second direction Y. In order to avoid the second end 102 from being reliably supported on the user's face area when the first end 102 extends into the concha cavity 502, resulting in reduced wearing stability, the distance L12 from the second reference point C2 to the first reference point C1 in the first direction X is between 20 mm and 31 mm. In addition, the second reference point C2 may also be a lowest point in the outer wall surface LS2 of the shell assembly 10 facing the user's ear in an arched shape. Optionally, the second reference point C2 is arranged to abut against the facial skin on the front side of the tragus 508 of the user's ear in the wearing state.

[0058] Further, in order to enable the earphone 100 to adapt to the ear shape of the user, the design of the distance L1 from the second reference point C2 to the first reference point C1 in the first direction X can be more targeted. In some embodiments, when the user's ear is small, in order to avoid the first end 102 being unable to abut the concha cavity 502 well when the second reference point C2 is supported 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 20mm to 24mm. In some embodiments, when the user's ear is large, in order to avoid the area where the second reference point C2 is located being supported on the antitragus and excessively compressing 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 or 26mm to 31mm. Specifically, the distance L12 from the second reference point C2 to the first reference point C1 in the first direction X can be 21.9mm, 23.4mm, 25mm, 26.4mm, 28.02mm.

[0059] 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.

[0060] 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 easy to over-press the user's tragus 508.

[0061] Generally, due to the volume limitation of the concha cavity 502, if the first end 102 is too large or too thick, it may be difficult to extend into the concha cavity 502. If the first end 102 is too small, the internal space is not easy to use.

[0062] Optionally, in the second direction Y, the outer wall surface LS2 of the shell 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 in the wearing state. In some embodiments, the third reference point C3 may be a 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 in the outer wall surface LS2 of the shell assembly 10 facing the user's ear in an arched shape.

[0063] 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. Further, in order to enable the earphone 100 to adapt to the ear shape of the user and to increase the internal space of the shell 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 concha cavity 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 is 3.45 mm, 3.8 mm, 4.29 mm, or 4.53 mm. In this case, the first end 102 of the shell assembly 10 can be easily inserted into the concha cavity 502, and the internal space is relatively easy to use (for example, to facilitate the assembly of the speaker 13).

[0064] If the arch G1 of the outer wall surface LS2 is too slightly recessed toward the inner side of the shell assembly 10, the outer wall surface LS2 may over-press the tragus 508 when the wearer is wearing the earphone. If the arch G1 of the outer wall surface LS2 is too deeply recessed toward the inner side of the shell assembly 10, the curvature of the outer wall surface LS2 and the corresponding inner wall surface LS1 (described later) of the shell assembly 10 may be too large, which is not conducive to the layout of various components inside the shell assembly 10.

[0065] Optionally, the distance H30 from the arch 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 arch 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 the wearing process, the outer wall surface LS2 is not easy to over-press the tragus 508, and the outer wall surface LS2 of the shell assembly 10 can also be prevented from being excessively bent.

[0066] In the existing earphones 100, the battery 14 and the speaker 13 are usually located in two independent shells, which also means that a longer wire is needed 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.

[0067] In some embodiments, the earphone 100 further includes a battery 14, which can supply power to the speaker 13. In the wearing state, since the first end 102 of the housing assembly 10 is closer to the external auditory canal of the user's ear than the second end 103, the speaker 13 can be arranged in the housing assembly 10 at a position closer to the first end 102, and the battery 14 can be arranged in the housing assembly 10 at a position closer to the second end 103. In this case, it is more conducive to the air conduction sound generated by the speaker 13 to be transmitted to the external auditory canal of the user, thereby ensuring the user's listening effect.

[0068] In some embodiments, the speaker 13 and the battery 14 can be arranged in the accommodation space 101 formed by the housing assembly 10 at intervals 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 the assembly efficiency, reducing the length of the connecting wire, and making the connecting wire arranged in the housing assembly 10 less likely to be damaged.

[0069] Furthermore, a partition wall 104 may be provided in the accommodation space 101 of the housing assembly 10, see Figure 6 The partition wall 104 can be used to separate the speaker 13 and the battery 14 to prevent the speaker 13 from being damaged by leakage of the battery 14. In some embodiments, the partition wall 104 can be integrally formed with the housing assembly 10, which can improve the consistency of the housing assembly 10. In some embodiments, the partition wall 104 can be formed separately and installed in the housing assembly 10 by means of snap-fitting, gluing, etc., which can reduce the difficulty of processing the housing assembly 10. Figure 4 and Figure 5 Exemplarily, a partition wall 104 adjacent to the dome G1 of the outer wall surface 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.

[0070] In some embodiments, the speaker 13 has a first axis ZX1, and the battery 14 has a second axis ZX2, and the first axis ZX1 and the second axis ZX2 respectively have a positive direction pointing to the user's ear in the wearing state. In the 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 crosswise. In other words, the speaker 13 and the battery 14 are arranged relatively tilted. 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 the 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 symmetry axis of the battery 14, and passing through the geometric center or the centroid of its two end faces.

[0071] Further, see Figure 5 , the intersection angle θ of the projection of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 in the reference plane is an acute angle. In order to ensure that the inclination angle between the battery 14 and the speaker 13 is not too large when the size of the housing assembly 10 along the first direction X is reduced, causing the size of the housing assembly 10 in the second direction Y to become larger, the intersection angle θ of the projection of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 in 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.

[0072] 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 to 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, so that the assembly difficulty of the battery 14 can be reduced. Among them, the radial dimension of the speaker 13 can refer to the length of the direction perpendicular to its first axis ZX1 in the cross section on the reference plane. The radial dimension of the battery 14 can refer to the length of the direction perpendicular to its second axis ZX2 in the cross section on the reference plane.

[0073] In this case, since the radial dimension of the speaker 13 is greater than the radial dimension of the battery 14, if the speaker 13 and the battery 14 are arranged side by side along the first direction X, the space occupied by the speaker 13 along the first direction X is larger. Therefore, when the speaker 13 is arranged obliquely relative to the second direction Y, compared with the battery 14 being arranged obliquely relative to the second direction Y, the influence on the degree of change of the projected length of the housing assembly 10 in the first direction X will be greater, thereby facilitating the reduction of the length of the housing assembly 10 in the first direction X.

[0074] The earphone 100 further includes a circuit board 15, which is disposed in the accommodation space 101 formed by the housing 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 the circuit board 15 can be one, and the wires connected to the battery 14 and the speaker 15 are used 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, see Figure 5 The circuit board 15 can be arranged along the first direction X. This 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. This arrangement can further reduce the volume of the housing assembly 10.

[0075] In some embodiments, the housing assembly 10 includes a first housing 111 and a second housing 112 that match each other along the second direction Y, the speaker 13 and the battery 14 can be fixed on the first housing 111, the first housing 111 is closer to the user's ear than the second housing 112 when worn, and the circuit board 15 is fixed on the second housing 112. In this case, it can facilitate the assembly of the earphone 100 and the disassembly and repair of the earphone 100. Among them, 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 columns 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 columns on the second housing 112, and the circuit board 15 can be fixed to the second housing by hot melting.

[0076] See also Figure 5 and Figure 8 The earphone 100 also includes a charging interface 16 disposed on the first shell 111 and a magnetic element 17 disposed between the battery 14 and the first shell 111 along the second axis ZX2. The magnetic element 17 is disposed between the battery 14 and the first shell 111, so that the accommodating space 101 can be fully utilized to increase the space utilization rate. In this case, the earphone 100 can be used in conjunction with a charging box 900 with a magnetic charging function.

[0077] See also Fig. 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 earphone 100 respectively, and the upper shell component 920 may cover the lower shell component 910 to close the contoured grooves 911.

[0078] Furthermore, the charging box 900 may include a main control circuit board disposed in the lower shell assembly 910 and electrode terminals 912 disposed on the main control circuit board. Among them, the electrode terminals 912 may be provided in multiple groups, for example, two groups, as required. The electrode terminals 912 may 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 may contact the electrode terminals 912 in the charging box 900 in a one-to-one correspondence 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 may be spaced apart along a straight line, for example, spaced apart from each other and collinear.

[0079] In addition, the charging box 900 may include a magnetic attraction structure (not shown) disposed in the lower shell assembly 910. The magnetic attraction 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 attraction structure and the magnetic attraction element 17 in the earphone 100 may form a magnetic attraction pair, so that the charging interface 16 is in one-to-one contact with the electrode terminal 912.

[0080] When the earphone 100 is in the wearing state, the first end 102 of the shell component 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 component 10 that is away from the user's ear cannot maintain a good fit with the cavum concha 502, the user's foreign body sensation may increase during the wearing process of the earphone 100, resulting in a reduced experience.

[0081] In some embodiments, the first direction X has a positive direction pointing from the second end 103 to the first end 102, and the outer wall surface LS3 of the shell assembly 10 on the side away from the user's ear may include a first arc-shaped transition zone 105. On the reference plane defined by the first direction X and the second direction Y, the first arc-shaped transition zone 105 gradually approaches the user's ear along the positive direction of the first direction X, thereby forming a first part of the first end 102. In the above manner, the outer surface of the shell assembly 10 can be gradually bent toward the side where the user's ear is located, thereby better adapting to the shape of the concha cavity 502 and reducing the foreign body sensation when the user wears it.

[0082] See also Figure 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 on the side away from the user's ear is larger, which can be beneficial to the arrangement of components inside the housing assembly 10 .

[0083] Considering that the speaker 13 and the battery 14 are arranged at an angle, if the extension length of the first arc-shaped transition zone 105 in the first direction X is too small, it may cause a part of the housing assembly 10 to have a larger size in the thickness direction, and the space utilization rate inside the housing assembly 10 is reduced. In some embodiments, the extension component L105 of the first arc-shaped transition zone 105 along the first direction X is not less than 16 mm. In this case, the thickness of the housing assembly 10 can be within a reasonable range at all locations, and the internal space utilization rate of the housing assembly 10 can also be improved.

[0084] 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 described again. At the first reference point C1, the angle α1 between the tangent of the first arc-shaped transition zone 105 and the second direction Y can be between 5 and 8 degrees. For example, at the first reference point C1, the angle α1 between the first arc-shaped transition zone 105 and the second direction Y is 5°, 5.5°, 6°, 6.5°, 7°, 7.5°, or 8°. In some embodiments, see Figure 7 and Fig.10 , the first arc-shaped transition zone 105 also has a first intermediate reference point C4 whose distance L14 from the first reference point C1 along the first direction X is between 1.8 mm and 3 mm. At the first intermediate reference point C4, the angle α2 between the tangent of the first arc-shaped transition zone 105 and the second direction Y is between 35° and 53°. In some embodiments, the first arc-shaped transition zone 105 has a second intermediate reference point C5 whose distance L15 from the first reference point C1 along the first direction X is between 6 mm and 9 mm. The angle α3 between the tangent of the first arc-shaped transition zone 105 and the second direction Y is between 60° and 80°.

[0085] 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.

[0086] 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 of the first arc-shaped 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, and at the second intermediate reference point C5, the angle α3 between the switch of the first arc-shaped transition zone 105 and the second direction Y is 70.8 degrees.

[0087] In some embodiments, in the second direction Y, the side of the shell 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 shell assembly 10 facing the user's ear includes a second arc-shaped transition zone 106 between the first reference point C1 and the third reference point C3, and the first direction X has a negative direction pointing from the first end 102 to the second end 103. Along the negative direction of the first direction X, the second arc-shaped transition zone 106 gradually approaches the user's ear, thereby forming a second portion of the first end 102. Optionally, the radius of curvature of the second arc-shaped transition zone 106 gradually increases along the negative direction of the first direction X, and gradually approaches the user's ear, thereby forming a second portion of the first end 102.

[0088] 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, so as to reduce the foreign body sensation when the first end 102 is inserted into the concha cavity 502, thereby improving the wearing experience of the user.

[0089] In some embodiments, 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 6 mm. Optionally, at the third reference point C3, the angle α4 between the tangent of the second arc-shaped transition zone 106 and the second direction Y is between 75 degrees and 95 degrees.

[0090] 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 a tangent line of the second arc-shaped transition zone 106 and the second direction Y is 84.9°.

[0091] Through the above method, 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 are limited respectively, so that the second arc-shaped transition zone 106 can better adapt to the inside of the user's concha cavity 502 and reduce the foreign body sensation.

[0092] Furthermore, the outer wall surface LS2 of the shell assembly 10 facing the user's ear also includes a third arc-shaped transition zone 107 located on the side of the third reference point C3 away from the first reference point C1, and the third arc-shaped transition zone 107 is arranged in an arch shape away from the user's ear. In the first direction X, the distance L10 from the arch top G1 of the third arc-shaped 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.

[0093] In some specific embodiments, the distance L10 from the dome G1 of the third arc-shaped 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 dome G1 of the third arc-shaped transition zone 107 is approximately located outside the tragus 508 of the user, thereby reducing the possibility of compressing the tragus 508.

[0094] like Fig.11 As shown, as described above, the host module 1 may include a housing assembly 10. The host module 1 may also include the above-mentioned speaker 13 and battery 14, etc.

[0095] Alternatively, if Fig.11As shown, the housing assembly 10 may include a housing 11 and a decorative cover 12. The housing 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 OS1 of the housing 11 and is used to form a touch positioning area 120 for the user to perform touch positioning. The host module 1 may also include a touch module 18. The touch module 18 may be disposed on the housing 11 and has a touch detection area 182 that at least partially overlaps with the touch positioning area 120. When the user touches the corresponding area on the decorative cover 12, it can be detected by the touch detection area 182.

[0096] The touch positioning area 120 can be used to locate the touch detection area 182. After the user feels the touch positioning area 120, he can roughly know that he has reached or is 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 the human-computer interaction function between the user. For example, it can realize functions such as volume adjustment, power on and off control, song switching, play and pause, and can also realize Bluetooth connection or disconnection operations, switching Bluetooth connection devices and other operations.

[0097] Furthermore, the housing 11 and / or the decorative cover 12 may be provided with a positioning protrusion 121, which is located in the touch positioning area 120 and protrudes from the outer side surface OS1 of the decorative cover 12 away from the housing 11. On the basis of providing a single touch navigation positioning in the touch positioning area 120, by setting the positioning protrusion 121 to protrude from the outer side surface OS1 of the decorative cover 12 away from the housing 11, it is convenient for the user to touch the positioning protrusion 121 when touching the housing 11, so that the positioning protrusion 121 can play a role of secondary touch navigation positioning on the basis of the decorative cover 12, so that the user can more accurately locate the touch detection area 182 through the positioning protrusion 121, thereby improving the convenience of touch operation. Moreover, the decorative cover 12 can bring a unique visual effect in decoration to the headset 100, and on the basis of the unique visual effect, it is combined with the touch detection area 182 (at least partially overlapped), and there is no need to set an additional detection area for touch, so that the volume of the headset 100 is smaller. The visual effect of the decorative cover 12 can also 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.

[0098] In some embodiments, Fig.11As shown, the outer side surface OS1 of the housing 11 and the outer surface OS2 of the decorative cover 12 can jointly form the outer side surface OS of the host module 1. The outer side surface OS of the host module 1 is arranged in an outwardly arched shape. In other words, the outer side surface OS1 of the housing 11 and the outer surface OS2 of the decorative cover 12 are arranged in an outwardly arched shape, which can increase the lateral space utilization of the earphone 100, so that the earphone 100 can arrange other components inside the shell assembly 10, and the outwardly arched arrangement can visually make the host module 1 smaller on the outer side surface OS.

[0099] In some embodiments, Fig.11 As shown, 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 which can be perpendicular to each other. The housing 11 is used to be stacked on the user's ear along the thickness direction Y when worn. Specifically, the length direction X of the housing 11 can be as shown in FIG. Fig.11 As shown by the arrow X in the figure, the thickness direction Y of the housing 11 can be as follows: Fig.11 As shown by the Y arrow in the figure, the width direction Z of the housing 11 can be as follows Fig.11 As shown by the Z arrow, the directions X, Y and Z are perpendicular to each other.

[0100] In some embodiments, Fig.12 As shown, the ratio of the dimensions of the decorative cover 12 and the housing 11 in the length direction X can be greater than or equal to 0.5 and less than or equal to 0.8. Fig.12 As shown in the length D, the size of the housing 11 in the length direction X can be as follows Fig.12 As shown in the middle length E. Among them, 0.5≤D / E≤0.8. For example, the ratio of the dimensions of the decorative cover 12 and the housing 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 housing 11 in the length direction X is greater than or equal to 0.6 and less than or equal to 0.7.

[0101] Optionally, the size ratio of the decorative cover 12 to the housing 11 in the width direction Z may be greater than or equal to 0.6 and less than or equal to 0.95. Fig.12 As shown in the middle length F, the size of the housing 11 in the width direction Z can be as follows Fig.12 As shown in the middle length G. Among them, 0.6≤F:G≤0.95. For example, the ratio of the dimensions of the decorative cover 12 and the housing 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 housing 11 in the width direction Z is greater than or equal to 0.7 and less than or equal to 0.87.

[0102] 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 .

[0103] 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.

[0104] In some embodiments, Fig.12 As shown, the positioning protrusion 121 can be arranged in a strip shape, and the extension direction H of the positioning protrusion 121 intersects with the length direction X and the width direction Z. The extension direction H of the positioning protrusion 121 can be as follows: Fig.12 As shown by the arrow H in the middle. Such a setting enables the positioning protrusions that intersect with the length direction X and the width direction Z to provide the user with a clear sense of touch when the user's hand touches, thereby facilitating the user's touch positioning and providing the user with a more obvious secondary touch navigation positioning.

[0105] Optionally, the extending 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 included angle α between the extending direction H of the positioning protrusion 121 and the length direction X of the housing 11 is as follows: Fig.12 Shown in center angle.

[0106] Optionally, the angle between the extension direction H of the positioning protrusion 121 and the length direction X of the housing 11 may be 30° to 70°, for example, the angle between the extension direction H of the positioning protrusion 121 and the length direction X of the housing 11 may be 40°, 50°, 60°, etc. This arrangement allows the positioning protrusion 121 to be easily touched and identified by the user.

[0107] In some embodiments, Fig.12 and Fig.14As shown, the housing 11 may have a connection 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) away from the connection end 103 in the length direction X. The housing 11 may be bent in the direction of the outer side surface OS1 of the housing 11 in the thickness direction Y, and the outer side surface OS of the housing 11 is bent in the direction so that the free end 102 is closer to the ear hole of the user's ear than the connection end 103, and the decorative cover 12 is closer to the connection end 103. Since the free end 102 is closer to the ear and the connection end 103 connected to the ear hook 2 is farther away from the ear when the earphone 100 is worn on the ear, the decorative cover 12 is arranged closer to the connection end 103, so that the user can touch the decorative cover 12 conveniently.

[0108] In some embodiments, Figure 13 to Figure 14 As shown, the housing 11 can be bent in the thickness direction Y in the direction of the outer side surface OS1 of the housing 11, so that the free end 102 is closer to the ear hole of the user's ear than the connection end 103. In this way, the decorative cover 12 can be located as much as possible in the area parallel to the sagittal plane of the human body when the earphone 100 is worn, and the area of ​​the curved surface of the decorative cover 12 extending toward the ear hole is reduced, so that the user can operate blindly and quickly locate the positioning protrusion 121.

[0109] In some embodiments, Fig.13 As shown, the free end 102 may have a first reference position K1 farthest from the connection end 103 in the length direction X, and the decorative cover 12 may have a second reference position K2 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 wearing state.

[0110] The housing 11 has an arc-shaped transition zone 114 between the first reference position K1 and the second reference position K2. From the second reference position K2 to the first reference position K1, the arc-shaped transition zone 114 gradually approaches the ear of the user along the thickness direction Y in the wearing state. Therefore, when the earphone 100 is worn in the wearing state, the earphone 100 portion corresponding to the arc-shaped transition zone 114 can gradually approach the ear of the user along the thickness direction Y or even fit the ear of the user, so that the free end 102 can better extend into the concha cavity 502, and the earphone 100 can improve the wearing comfort and stability. Moreover, the arc-shaped transition 114 starts from the second reference point position K2 of the decorative cover 12, and gradually tilts toward the first reference position K1 in an arc shape, so that the second reference position K2 can be used as a turning point, so that the user can more effectively locate the decorative cover 12, and then locate the touch positioning area 120, thereby improving the convenience of touch. And the edge of the decorative cover 12 is close to the demarcation point of the curve turning of the housing 11, so that the user can more easily identify and locate the decorative cover 12 when operating blindly.

[0111] In some embodiments, the roughness of the outer surface OS2 of the decorative cover 12 may be greater than the roughness of the outer surface OS1 of the housing 11. In this way, when a user touches the decorative cover 12 and the outer surface OS1 of the housing 11, the difference in roughness can bring a difference in tactile sensation to the user, and the decorative cover 12 and the housing 11 can be easily distinguished, thereby facilitating the user to locate the touch detection area 182 for touch control, thereby improving the convenience of touch control.

[0112] 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 may be red, blue, etc., and the color of the outer surface OS1 of the outer shell 11 may 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 generated on the outer surface OS of the host module 1, thereby visually making the size of the entire host module 1 smaller, 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, so that the user can easily know the position of the touch detection area 182, reduce the learning cost, and improve the touch efficiency.

[0113] In some embodiments, the material of the decorative cover 12 may be different from that of the outer shell 11. For example, the material of the decorative cover 12 may be a transparent acrylic plate, and the material of the outer shell 11 may be a metal material. Alternatively, the material of the decorative cover 12 may be a metal material, and the material of the outer shell 11 may be made of materials such as plastic and resin. The setting that the material of the decorative cover 12 is different from that of the outer shell 11 can also facilitate users to distinguish the decorative cover 12 from the outer shell 11, and the difference in material can more easily improve the decorative effect of the decorative cover 12, and the difference in material can bring differentiated touch textures to users, thereby making it easier for users to perform touch operations and improving the convenience of touch.

[0114] In some embodiments, Fig.14 As shown, at least part 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 surrounded by at least part of the edge of the decorative cover 12 exposed on the outer side surface OS1 of the housing 11. When the user touches the outer side surface OS1 of the housing 11, the user can touch at least part of the edge of the decorative cover 12. Since the existence of the edge can provide a tactile sensation for the user, the user can clearly know that the corresponding area has been touched, which effectively plays a role in navigation positioning.

[0115] Optionally, the edge of the decorative cover 12 can be arranged in a ring shape and completely exposed to the outer side surface OS1 of the outer shell 11 to enclose 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 to the outer side surface OS1 of the outer shell 11, and the user can touch the complete edge of the decorative cover 12, which has a better positioning effect and further improves the user's touch efficiency. In addition, the positioning protrusion 121 is arranged in the middle position of the decorative cover 12 and is not close to the edge of the decorative cover 12. Such an arrangement can make the position of the positioning protrusion 121 more stable and not easy to fall from the decorative cover 12 enclosed to form the touch positioning area 120.

[0116] In some embodiments, Fig.14 As shown, the housing 11 may be provided with a positioning groove 113 on the outer side surface, and the decorative cover 12 is received in the positioning groove 113 through the notch of the positioning groove 113 .

[0117] 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.

[0118] 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 feeling that is clearly different from other positions. When the user touches the seam, he can quickly and effectively know that the corresponding area has been touched, which can improve the user's touch efficiency.

[0119] In some embodiments, the positioning protrusion 121 can be protruded from the outer side surface OS1 of the housing 11, and the decorative cover 12 is provided with a positioning hole 122, and the positioning protrusion 121 is passed through the positioning hole 122. Through the positioning hole 122 and the positioning protrusion 121, the decorative cover 12 and the outer side surface OS1 of the housing 11 can be accurately assembled, so that the position of the touch detection area 182 can be more accurate. Furthermore, through the cooperation of the positioning groove 113 and the positioning protrusion 121, the assembly accuracy between the decorative cover 12 and the housing 11 can be further enhanced, and the touch positioning area 120 can provide a more accurate positioning for the touch detection area 182, thereby improving the accuracy and convenience of touch.

[0120] Optionally, the positioning protrusion 121 can be protruding 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 less likely to detach from the decorative cover 12. In addition, 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.

[0121] Optionally, at least two sound pickup holes 115 may be provided on the outer side surface OS of the host module 1. The two sound pickup holes 115 may be respectively located on two opposite slopes of the outer side surface OS of the host module 1. By arranging the two sound pickup holes 115 on two opposite slopes, the two sound pickup holes 115 point in different directions, thereby expanding the sound pickup range of the earphone 100, and pointing in different directions can reduce the mutual interference between the two sound pickup holes 115.

[0122] 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.

[0123] The positional relationship between the touch detection area 182 and the positioning protrusion 121 can be in various forms.

[0124] 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's usage experience.

[0125] 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. Or 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.

[0126] In some embodiments, Figure 15 to Figure 16 As shown, the touch module 18 may include a touch metal pattern 181 and a circuit board 15. The circuit board 15 may be disposed inside the housing 11. The touch metal pattern 181 may be disposed 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.

[0127] When the user touches and / or presses the touch positioning area 120 or the positioning protrusion 121, it can trigger the touch metal pattern 181 that senses and forms 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.

[0128] In some embodiments, the touch metal pattern 181 can also be configured as a radio frequency antenna of 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, so that the headset 100 can interact with other devices.

[0129] Of course, the number of the sound pickup hole 115 can be at least one. The sound pickup hole 115 at least penetrates the housing 11, connecting the external environment and the accommodating space 101. Accordingly, the host module 1 may also include a microphone 19. The microphone 19 is disposed in the accommodating space 101 and is disposed corresponding to the sound pickup hole 115, so as to pick up the sound of the external environment through the sound pickup hole 115.

[0130] Alternatively, if Figures 17 to 20 As shown, 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 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.

[0131] 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 when touching the decorative cover 12, thereby reducing the impact on the sound pickup effect.

[0132] Optionally, taking two sound pickup holes 115 as an example, the distance between the two sound pickup holes 115 is greater than or equal to the size of the decorative cover 12 along the arrangement direction of the two microphones 19. Since one is arranged outside the decorative cover 12, such an arrangement allows the other to be located at the edge of the decorative cover 12 as much as possible, so that the distance between the two sound pickup holes 115 is larger, and when the touch positioning area 120 of the decorative cover 12 is touched, it is not easy to block the sound pickup hole 115 located outside the decorative cover 12, nor is it easy to block the sound pickup hole 115 close to the edge of the decorative cover 12, thereby further reducing the probability of blocking both sound pickup holes 115 when touching the decorative cover 12, thereby reducing the impact on the sound pickup effect.

[0133] Alternatively, if Fig.17As shown, the touch positioning area 120 is located between the two sound pickup holes 115. With this arrangement, when the touch positioning area 120 is touched, it is not easy to block the two sound pickup holes 115, thereby reducing the impact on the sound pickup effect.

[0134] 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 toward the "lower left", on the one hand, so that the sound pickup hole 115 that passes through the decorative cover 12 is 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, which is convenient for noise reduction processing and improves the sound pickup quality 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.

[0135] Alternatively, if Figures 18 to 20 As shown, the host module 1 may further include a sealing component 190, at least a portion of which is disposed between the housing 11 and the microphone 19, for isolating a sound pickup passage from the accommodating space 101, so that the sound pickup passage is sealed relative to a portion of the space outside the sound pickup passage of the accommodating space 101, thereby reducing the influence of dust, water vapor, etc. that enters the sound pickup passage through the sound pickup hole 115 on other electrical components in the accommodating space 101.

[0136] Optionally, the host module 1 may further include a fixing plate for fixing the microphone 19. Optionally, the fixing plate may be a circuit board 15. Or in other embodiments, the fixing plate may also be a plate-shaped structural member other than the circuit board 15, or a part of the housing assembly 10, which may be used to fix the microphone 19 and may further fix other components.

[0137] like Figures 18 to 20 As shown, the fixing plate is accommodated in the accommodating space 101 and is provided with a through hole 151, and the microphone 19 is fixed to one side of the fixing plate and covers the through hole 151. At least part of the sealing component 190 is arranged in the accommodating space 101 and abuts between the housing 11 and the side of the fixing plate away from the microphone 19, and the through hole 151 and the sound pickup hole 115 are connected to each other. Such an arrangement can improve the installation stability and sealing performance of the sealing component 190.

[0138] 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.

[0139] In some embodiments, for the sound pickup hole 115 that penetrates the housing 11 and is located at the periphery of the decorative cover 12, the structure of the sealing assembly 190 and the related description examples are as follows:

[0140] like Fig.18 and Fig.19 As shown, the microphone 19 can penetrate the housing 11 and be located at the periphery of the decorative cover 12. The sealing assembly 190 can include a sealing rubber ring 191a and a gauze assembly 192a, the sealing rubber ring 191a and the gauze assembly 192a are stacked, and the sealing rubber ring 191a and the gauze assembly 192a are both arranged in the accommodating space 101 and located 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, thereby further improving the sealing effect.

[0141] Optionally, the sealing rubber ring 191a is stacked on the fixing plate, and is closer to the through hole 151 than the gauze assembly 192a. The gauze assembly 192a is located between the sealing rubber ring 191a and the housing 11, and is closer to the sound pickup hole 115 than the sealing rubber ring 191a. In this way, the gauze assembly 192a is placed in front of the sealing rubber ring 191a (i.e., closer to the sound pickup hole 115), which can reduce the accumulation of dust, impurities, etc. on the sealing rubber ring 191a, and thus can prevent dust, impurities, water vapor, etc. from entering the accommodating space 101 as early as possible.

[0142] In other embodiments, for the sound pickup hole 115 that runs through the housing 11 and the decorative cover 12, the structure of the sealing assembly 190 and the related description examples are as follows:

[0143] like Fig. 20As shown, the microphone 19 can pass through the housing 11 and the decorative cover 12, and the sealing component 190 can include a sealing rubber ring 191b and at least one gauze component 192b. The sealing rubber ring 191b is arranged in the accommodating space 101 and between the housing 11 and the fixing plate, and directly abuts against the housing 11 and the fixing plate. At least one gauze component 192b is arranged between the housing 11 and the decorative cover 12. Since the matching between the decorative cover 12 and the housing 11 and the matching between the sealing component 190 and the fixing plate are prone to accumulate large errors, connecting the sealing rubber ring 191b with stronger deformation ability to the fixing plate can reduce the matching errors between the decorative cover 12 and the housing 11 and between the sealing component 190 and the fixing plate, thereby ensuring the sealing effect of the circuit accessories.

[0144] 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 fixing plate.

[0145] By arranging the mesh component 192b between the housing 11 and the decorative cover 12, on the one hand, it is possible to reduce dust, impurities, water vapor, etc. from entering the accommodating space 101, and on the other hand, the mesh component 192b can seal the sound pickup hole 115 between the housing 11 and the decorative cover 12, reducing water vapor from entering between the housing 11 and the decorative cover 12 from the sound pickup hole, thereby affecting the connection stability between the two. By arranging the sealing rubber ring 191b in the accommodating space 101 and sealing between the housing 11 and the fixing plate, the sealing effect is further improved, reducing the water vapor entering from the sound pickup hole 115 from leaking into the accommodating space 101 and causing adverse effects on other electrical devices inside.

[0146] For the above-mentioned gauze components 192a, 192b, the structures thereof are described exemplarily as follows:

[0147] like Figures 19 to 20As shown, the gauze assembly 192a, 192b includes an annular double-sided adhesive tape 1921 and a gauze 1922. The annular double-sided adhesive tape 1921 is stacked with the gauze 1922 and bonded to the gauze 1922. Specifically, one side of the annular double-sided adhesive tape 1921 can be bonded to the gauze 1922, and the other side can be connected to the housing 11 or the decorative cover 12 close to it. 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 adhesive tape 1921 can be bonded to the gauze 1922, and the other side can be bonded 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 adhesive tape 1921 can be bonded to the gauze 1922, and the other side can be bonded 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 adhesive tape 1921 surrounds the periphery of the sound pickup hole 115 , and the mesh 1922 is located in the middle of the annular double-sided adhesive tape 1921 and is arranged opposite to the sound pickup hole 115 .

[0148] Optionally, the number of the annular double-sided adhesive tape 1921 is two layers, the number of the gauze 1922 is one layer, and the gauze 1922 is laminated and bonded between the two layers of the annular double-sided adhesive tape 1921. By providing a double layer of annular double-sided adhesive tape 1921, the bonding strength of the gauze 1922 can be enhanced, the gauze 1922 can be better fixed, and the thickness can be increased, so that it can be more tightly sealed 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.

[0149] Optionally, the number of the annular double-sided adhesive tape 1921 is two layers, the number of the gauze 1922 is two layers, the two layers of the annular double-sided adhesive tape 1921 are arranged at intervals, one layer of the gauze 1922 is laminated and bonded between the two layers of the annular double-sided adhesive tape 1921, and one layer of the annular double-sided adhesive tape 1921 is laminated between the two layers of the gauze 1922. By providing a double layer of gauze 1922, the filtering and blocking effects can be further enhanced, and the provision of a double layer of annular double-sided adhesive tape 1921 can effectively fix the double layer of gauze 1922, and can also further increase the thickness, thereby being able to more tightly 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] Combination Figure 21 to Figure 23 As mentioned above, the earphone 100 may include a housing assembly 10 and a speaker 13. Optionally, the earphone 100 may further include a sealant (not marked). The housing assembly 10 is used to form a first accommodating cavity 1011. The speaker 13 includes a basin frame 131 and a metal pad 132. Fig.24 and Fig.25The frame 131 is disposed in the first accommodating cavity 1011, and the metal pad 132 is disposed on the frame 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 frame 131 and the inner peripheral wall of the first accommodating cavity 1011.

[0151] 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 damaging electronic components.

[0152] In the process of dispensing the sealant, it is often necessary to dispense the sealant around the basin frame 131 so that the sealant is continuously filled 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 between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011. In the prior art, the metal pad 132 is often arranged to extend from the basin frame 131 to the outside of the inner peripheral wall of the first accommodating cavity 1011 to connect the power supply outside the first accommodating cavity 1011. When dispensing the sealant, the pad will form a large shielding on the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011, which is not convenient for dispensing the sealant near the pad. There is a risk of interruption of the sealant at the pad, which reduces the sealing reliability.

[0153] 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 at the pad during the dispensing process, thereby facilitating dispensing at the pad and facilitating continuous filling of the sealant between the outer wall of the basin frame 131 and the inner wall of the first accommodating cavity 1011 to achieve a stable and reliable sealing effect.

[0154] 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 less blocks 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.

[0155] Combination Figure 23 to Figure 25 In some embodiments, the metal pad 132 is configured not to extend beyond the outer peripheral wall of the basin frame 131 .

[0156] Such a configuration ensures that during the glue 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 glue dispensing operation and helps to achieve a stable and reliable sealing effect.

[0157] Combination Fig.23 , Fig.24 and Fig.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.

[0158] Such a configuration ensures that during the 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 the dispensing operation can still be performed at the metal pad 132. By setting the excess distance S1 of the metal pad 132 relative to the outer peripheral wall of the basin frame 131 to be no greater than half of 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 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 at the pad. Since the sealant has a certain fluidity during dispensing, the fluidity of the sealant can be used to fully fill the sealant 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.

[0159] In some embodiments, in combination Fig.23 , Fig. 27 and Fig.28 The first accommodating cavity 1011 has an open end 1014, the basin frame 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 frame 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.

[0160] During the assembly process of the basin frame 131, the surrounding side of the basin frame 131 and the side of the basin frame 131 facing away from the opening end 1014 will contact 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.

[0161] Combination Figure 23 to Figure 25 In some embodiments, the sealant is applied from one side of the opening end 1014 to the gap between the outer peripheral wall of the basin frame 131 and the inner peripheral wall of the first accommodating cavity 1011 .

[0162] 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 opening end 1014, so that it is convenient to dispense glue from the outside through the opening end 1014 to 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 one side of the opening end 1014. Such a configuration facilitates the dispensing operation and improves assembly efficiency.

[0163] Combination Figure 27 to Figure 29 In some embodiments, the earphone 100 further includes a bracket 134, the frame 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 frame 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 frame 131, the metal pad 132 is arranged on the assembly table 1312, and the bracket 134 is supported on the annular table 1311.

[0164] The assembly table 1312 can sink relative to the annular table 1311 at the first notch 1313 in a direction away from the open end 1014. The metal pad 132 often has a certain protrusion height. By setting the annular table 1311 to have the first notch 1313, the bracket 134 can avoid the metal pad 132 and the wire 133 when supported on the annular table 1311, which facilitates the assembly of the bracket 134 and the basin frame 131 and improves the assembly efficiency.

[0165] In some embodiments, in combination 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 the position of the assembly table 1312 along the circumference of the basin frame 131 .

[0166] 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 the assembly efficiency.

[0167] In some embodiments, in combination Figure 22 to Figure 24 The shell assembly 10 further forms a second accommodating cavity 1012. 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. The metal pad 132 is located on the side of the basin frame 131 facing the partition wall 104.

[0168] A portion of the inner circumferential wall of the first accommodating chamber 1011 may be formed by the 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. By providing the partition wall 104, the risk of water flowing from the side of the speaker 13 close to the sound outlet 1013 to the second accommodating chamber 1012 may be reduced.

[0169] The battery 14 can be used as a power source to supply power to the speaker 13. The first accommodating cavity 1011 and the second accommodating cavity 1012 are arranged adjacent to each other, which is conducive to simplifying the connection line between the battery 14 and the speaker 13. By arranging the metal pad 132 on the side of the basin frame 131 facing the partition wall 104, the spacing distance between the battery 14 and the metal pad 132 can be reduced, which is conducive to further simplifying the connection line between the battery 14 and the speaker 13. Furthermore, the metal pad 132 can be connected to the battery 14 through the wire 133, so that the battery 14 supplies power to the speaker 13.

[0170] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
