Description

TECHNICAL AREA

[0001] The present utility model relates to the technical field of electronic devices, in particular an earphone. STATE OF THE ART

[0002] With the increasing popularity of electronic devices, they have become indispensable tools for communication and entertainment in everyday life. People's demands on electronic devices have also steadily risen. As electronic devices, earphones, smart glasses, and similar products are widely used in daily life. They can work together with devices such as mobile phones and computers to provide users with a fantastic audio experience.

[0003] However, some conventional earphones have problems of pressing on the user's ear or feeling uncomfortable if they cannot adapt to the shape of the user's ear. REVELATION OF THE INVENTION

[0004] The present application provides an earphone comprising: a housing arrangement serving to form a recording space and having a first direction and a second direction orthogonal to the first direction; an ear hook connected to the housing arrangement, wherein, when worn, the ear hook is located at least partially at the back of the user's ear and the housing arrangement is stacked in the second direction against the front of the user's ear;a loudspeaker and a battery, which are arranged spaced apart from each other in the recording space, wherein the loudspeaker has a first axis and the battery has a second axis, wherein the first axis and the second axis each have a positive direction which, when worn, points towards the user's ear, wherein the projections of the first axis and the second axis intersect in a reference plane defined by the first direction and the second direction.

[0005] In this case, the loudspeaker and the battery are arranged at an angle relative to each other. Compared to a design where the loudspeaker and battery are arranged side by side, this allows for a reduction in the length of the housing assembly in the first direction. This enables the housing assembly to be both stably supported when carried and to extend into the cavity.

[0006] In some embodiments, the angle of intersection between the projections of the first axis in its positive direction and the second axis in its positive direction onto the reference plane is an acute angle.

[0007] In some embodiments, the cutting angle is provided to be between 10° and 14°.

[0008] In some embodiments, the housing arrangement has a first end and a second end which are arranged facing away from each other in the first direction, wherein, in the worn state, the first end is closer to the cavum conchae of the user's ear compared to the second end, and wherein the loudspeaker is arranged close to the first end and the battery is arranged close to the second end.

[0009] In some embodiments, a partition is provided in the housing arrangement, with the loudspeaker being located in the receiving space between the partition and the first end.

[0010] In some embodiments, it is provided that the radial dimension of the loudspeaker is larger than the radial dimension of the battery on the reference plane, wherein the second direction has a positive direction pointing towards the user's ear, wherein the angle of intersection between the projection of the positive direction of the first axis onto the reference plane and the positive direction of the second direction is greater than the angle of intersection between the projection of the positive direction of the second axis onto the reference plane and the positive direction of the second direction.

[0011] In some embodiments, the second axis is provided to run parallel to the second direction.

[0012] In some embodiments, the earphone further comprises a circuit board arranged in the receiving space, the circuit board being located on an inner wall surface of the housing facing away from the user's ear, and its projection in the second direction at least partially overlapping with the loudspeaker and the battery.

[0013] In some embodiments, the housing arrangement comprises a first housing and a second housing that are fitted to each other in the second direction, with the loudspeaker and the battery attached to the first housing, the first housing being closer to the user's ear when worn compared to the second housing, and the circuit board being attached to the second housing.

[0014] In some embodiments, the earphone further comprises a charging interface provided on the first housing and a magnetic element provided in the direction of the second axis between the battery and the first housing.

[0015] In some embodiments, the printed circuit board is attached to the second housing by hot melting. BRIEF DESCRIPTION OF THE FIGURES

Detailed descriptions

[0017] The present application is described in more detail below with reference to the accompanying drawings and the exemplary embodiments. It is particularly emphasized that the following exemplary embodiments serve only to illustrate the present application and do not limit its scope. Similarly, the following exemplary embodiments represent only some of the exemplary embodiments, rather than all of them, of the present application. All other exemplary embodiments that would be obtained by a person skilled in the art in this field without inventive steps are also within the scope of protection of the present application.

[0018] The term "exemplar embodiment" mentioned in the present application should be understood to mean that certain features, structures, or properties described by reference to the embodiment may be included in at least one embodiment of the present application. It is implicitly and explicitly understood by those skilled in the art that the embodiments described in the present application can be combined with other embodiments.

[0019] Combined with Fig. 1. An ear 500 of a user may comprise an external auditory canal 501, a cavum conchae 502, a cymba conchae 503, a fossa triangularis 504, an antihelix 505, a scapha 506, a helix 507, a tragus 508, and other physiological sections. While the external auditory canal 501 has a certain depth and extends to the tympanic membrane of the ear, for the sake of simplicity of description and in connection with Fig. 1, unless otherwise specified, is specifically defined as its entrance facing away from the tympanic membrane (namely the ear opening). Furthermore, it is provided that physiological sections such as the cavum conchae 502, the cymba conchae 503, and the fossa triangularis 504 each have a specific volume and depth; in addition, the cavum conchae 502 communicates directly with the external auditory canal 501, which can be simplified to mean that the aforementioned ear opening is located at the bottom of the cavum conchae 502.

[0020] Furthermore, it is anticipated that individual variations may exist among different users, leading to different shapes, sizes, and other dimensions of the ears. To simplify the description and reduce (or even eliminate) individual variations between different users, a simulator with a head and (left / right) ear, such as the GRAS 45BC KEMAR, can be manufactured based on the standards ANSI: S3.36, S3.25 and IEC: 60318-7. Therefore, expressions such as "the user wears the earphone 100," "the earphone 100 is in the worn state," and "in the worn state" in the present application can refer to the earphone 100 being worn on the ear of the aforementioned simulator according to the present application.Naturally, individual variations between different users may lead to differences when the earbud 100 is worn by different users, compared to wearing the earbud 100 on the ear of the aforementioned simulator. However, these variations should be tolerable.

[0021] With reference to Fig. In figures 2 to 5, the earphone 100 can comprise a main module 1 and an ear hook 2. The main module 1 can comprise a housing assembly 10 and a loudspeaker 13. The ear hook 2 can be hook-shaped. The earphone 100 can be worn via the ear hook 2 at a position near the user's outer ear canal without blocking the outer ear canal. The ear hook 2 can be connected to the housing assembly 10. When worn, the housing assembly 10 is located at the front of the ear, and the ear hook 2 rests at least partially at the back of the user's ear, allowing the earphone 100 to be suspended from the ear. Furthermore, the housing assembly 10 can serve to form a recording space 101. The loudspeaker 13 can be located within the recording space 101.The housing arrangement 10 is provided with a sound outlet opening which serves to transmit the airborne sound generated by the loudspeaker 13 into the outer ear canal of the user's ear.

[0022] To better describe the shape of the housing arrangement 10, a first direction X and a second direction Y are defined for the housing arrangement 10 in the present application, wherein the first direction X can be orthogonal to the second direction Y (see Fig. 5) Here, the first direction X can denote the length direction of the housing arrangement 10 and the second direction Y can denote the thickness direction of the housing arrangement 10.

[0023] In the worn state, the housing assembly 10 is stacked in the second direction Y against the front of the user's ear. The housing assembly 10 further comprises a first end 102 and a second end 103, which are arranged facing away from each other in the first direction X. In some embodiments, the first end 102 may denote the portion that, during wear, faces the user's concha 502, while the second end 103 may denote the portion that is farther from the user's concha 502 compared to the first end 102. In some embodiments, the first end 102 may denote the portion that, during wear, is closer to the back of the user's ear, and the second end 103 may denote the portion that is farther from the back of the user's ear compared to the first end 102.Part of the second end 103 can be connected to the ear hook 2 and may be referred to below as the connecting end 103, while the first end 102 may be referred to below as the free end 102.

[0024] In some embodiments, the first end 102 of the housing assembly 10 extends at least partially into the concha 502 of the user's ear, thereby ensuring that the external auditory canal remains open. The open state of the user's external auditory canal refers to the fact that the housing assembly 10 does not completely close off or block the external auditory canal, allowing the external auditory canal to communicate with the environment. Furthermore, due to individual variations among different users, the external auditory canal might be partially covered by the housing assembly 10 when the earphone 100 is worn by different users, but the external auditory canal would still not be completely blocked and could continue to communicate with the environment.

[0025] In some embodiments, with reference to Fig. 5, Fig. 6 and Fig. 7 In the second direction Y, an outer wall surface LS2 of the housing assembly 10 of the main module 1, facing the user's ear in the worn state, is designed to curve away from the user's ear. This design allows the construction of the housing assembly 10 to be better adapted to the shape of the user's ear, thereby reducing the pressure of the housing assembly 10 on the user's ear, particularly on the tragus 508. Furthermore, the restriction imposed by a flat extension direction is eliminated, allowing the first end 102 of the housing assembly 10 to protrude more efficiently into the user's concha 502, thus improving wearing comfort and stability.

[0026] The structural design of the outer wall surface LS2 of the housing assembly 10, which faces the user's ear when worn, affects the entire structure of the housing assembly 10 and consequently influences the user's comfort. For example, the structure of the outer wall surface LS2 affects the position of the first end 102 of the housing assembly 10. If the design of the outer wall surface LS2 results in the housing assembly 10 having an excessively short extension, it may be difficult for the first end 102 of the housing assembly 10 to penetrate the user's conchae 502, or it may result in the outer wall surface LS2 not being able to sufficiently deflect the user's tragus 508 when the first end 102 of the housing assembly 10 penetrates the user's conchae 502, leading to excessive pressure on the user's tragus 508.Similarly, if the design of the outer wall surface LS2 causes the housing arrangement 10 to have excessive extension, the pressure of the first end 102 on the antihelix 505 and the cavum conchae 502 could be increased, or it could cause the outer wall surface LS2 to not be able to sufficiently deflect the tragus 508 of the user, which would also result in excessive pressure on the tragus 508 of the user.

[0027] With reference to Fig. 6 The first end 102 optionally has a first reference point C1 in the first direction X, which is located furthest from the second end 103. In some embodiments, the first reference point C1 can be the point of the first end 102 furthest from the second end 103 in the first direction X. In some embodiments, the first reference point C1 can be the point of the first end 102 furthest from the second end 103 in the tangent direction of the arc apex of the outer wall surface LS2.To prevent the curved design of the outer wall surface LS2 from causing the part of the housing assembly 10 closer to the first end 102 to be too short or too long, thus preventing optimal adaptation of the first end 102 to the cavum conchae 502 and reducing user comfort, the distance L10 between the apex G1 of the outer wall surface LS2 and the first reference point C1 in the first direction X is between 14 mm and 20 mm. The apex G1 of the outer wall surface LS2 can refer to either the deepest point in this curved area or the point furthest from the user's ear in this curved area. The distance between the apex G1 and the first reference point C1 in the first direction X can be defined as the projection length of the line connecting the apex G1 and the first reference point C1 in the first direction X.

[0028] Furthermore, it is provided that, to enable the earphone 100 to be adapted to the shape of the user's ear, the distance L10 between the apex of the arc G1 of the outer wall surface LS2 and the first reference point C1 in the first direction X can be specifically designed. In some embodiments, if the user has a smaller ear, the distance L10 between the apex of the arc G1 of the outer wall surface LS2 and the first reference point C1 in the first direction X can be 14 mm to 16 mm to prevent the curved design of the outer wall surface LS2 from causing the part of the housing assembly 10 closer to the first end 102 to be too long and press against the conchae 502 of the user's ear.In some embodiments, if the user has a larger ear, the distance L10 between the apex of the arc G1 of the outer wall surface LS2 and the first reference point C1 in the first direction X can be 18 mm to 20 mm. This prevents the curved design of the outer wall surface LS2 from causing the part of the housing assembly 10 closer to the first end 102 to be too short, thus preventing the first end 102 from sufficiently contacting the cavity 502 and resulting in reduced stability. Specifically, the distance L10 between the apex of the arc G1 of the outer wall surface LS2 and the first reference point C1 in the first direction X can be 14.1 mm, 15.2 mm, 16.5 mm, 17.7 mm, 18.6 mm, or 19.9 mm.

[0029] Optionally, the outer wall surface LS2 of the housing assembly 10, facing the user's ear, has a second reference point C2 in the second direction Y, which is adjacent to the second end 103 and, when worn, is closest to the user's ear. In some embodiments, the second reference point C2 can be the point on the outer wall surface LS2 that is closest to the second end 103 and furthest away from the apex of the arch G1 or from the decorative cover (described later) in the second direction Y. To prevent the second end from being reliably supported in the user's facial area, thus reducing wearing stability if the first end 102 protrudes into the cavum conchae 502, 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.Additionally, the second reference point C2 can also be the lowest point in the curved outer wall surface LS2 of the housing assembly 10, which faces the user's ear. Optionally, the second reference point C2 is designed to abut against the skin of the human face in front of the tragus 508 of the user's ear when worn.

[0030] Furthermore, it is provided that, to allow the earphone 100 to adapt to the user's ear shape, the distance L1 between the second reference point C2 and the first reference point C1 in the first direction X can be specifically designed. In some embodiments, for users with smaller ears, the distance L12 between the second reference point C2 and the first reference point C1 in the first direction X can be 20 mm to 24 mm to prevent the first end 102 from insufficiently contacting the concha 502 when the second reference point C2 is supported against the antitragus. In some embodiments, for users with larger ears, the distance L12 between the second reference point C2 and the first reference point C1 in the first direction X can be 26 mm to 31 mm to prevent the area where the second reference point C2 is located from being supported against the antitragus and exerting excessive pressure on the user's antitragus.Specifically, the distance L12 between the second reference point C2 and 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.

[0031] In this case, the earphone 100 can be more stably supported by the second reference point C2 in the skin area of ​​the human face in front of the user's tragus 508. Furthermore, the first end 102 can protrude into the cavum conchae 502 without exerting excessive pressure on the antihelix 505, while the earphone 100 is supported by the second reference point C2 in the skin area of ​​the human face in front of the user's tragus 508.

[0032] Optionally, the distance H20 between the apex of the arc G1 on the outer surface LS2 and the second reference point C2 in the second direction Y is between 1.3 mm and 2.2 mm. Furthermore, to allow the earphone 100 to adapt to the user's ear shape, the distance H20 between the apex of the arc G1 on the outer surface LS2 and the second reference point C2 in the second direction Y can be specifically designed. Specifically, the distance H20 between the apex of the arc G1 on the outer surface LS2 and 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, the outer wall surface LS2 does not exert excessive pressure on the user's tragus 508, even when the earphone 100 is supported by the second reference point C2 in the skin area of ​​the human face in front of the user's tragus 508.

[0033] Due to the limited volume of the cavum conchae 502, an excessively large volume or thickness of the first end 102 can generally make it difficult to penetrate the cavum conchae 502. Conversely, if the volume of the first end 102 is too small, the internal space can only be used efficiently with difficulty.

[0034] Optionally, the outer wall surface LS2 of the housing assembly 10, facing the user's ear, has a third reference point C3 in the second direction Y, which is adjacent to the first end 102 and, when worn, is closest to the user's ear. In some embodiments, the third reference point C3 can be the point on the outer wall surface LS2 that is closest to the first end 102 and furthest from the apex of the arc G1 in the second direction Y. In some embodiments, the third reference point C3 can also be the other lowest point in the curved outer wall surface LS2 of the housing assembly 10, which faces the user's ear.

[0035] Optionally, the distance L13 between the third reference point C3 and 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 user's ear shape and simultaneously to enlarge the internal space of the housing assembly 10, the distance L13 between the third reference point C3 and the first reference point C1 in the first direction X should be as small as possible without unduly compressing the cavum conchae 502. For example, the distance L13 between the third reference point C3 and 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 between the third reference point C3 and 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 arrangement 10 can easily protrude into the Cavum conchae 502 and the interior space can be used efficiently (e.g., this makes it easier to mount the loudspeaker 13).

[0036] If the degree to which the apex of the arc G1 of the outer wall surface LS2 is recessed towards the inside of the housing assembly 10 is too small, the outer wall surface LS2 may exert excessive pressure on the tragus 508 when bearing weight. If the degree to which the apex of the arc G1 of the outer wall surface LS2 is recessed towards the inside of the housing assembly 10 is too large, this may lead to excessive curvature of the outer wall surface LS2 and the corresponding inner wall surface LS1 (described later) of the housing assembly 10, which may negatively affect the arrangement of individual components within the housing assembly 10.

[0037] Optionally, the distance H30 between the arc apex G1 of the outer wall surface LS2 and the third reference point C3 in the second direction Y is between 2 mm and 3 mm. For example, the distance H30 between the arc apex G1 of the outer wall surface LS2 and 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, it is largely prevented that the outer wall surface LS2 exerts excessive pressure on the tragus 508 when bearing the load, and excessive curvature of the outer wall surface LS2 of the housing assembly 10 can also be avoided.

[0038] In an existing earphone 100, the battery 14 and the speaker 13 are typically housed in two separate casings. This necessitates a longer connecting wire between the battery 14 and the speaker 13. During assembly of the earphone 100 or during use by the user, this wire frequently breaks due to external forces, rendering the earphone 100 unusable. Furthermore, the separate housing of the battery 14 and the speaker 13 increases the dimensions of the earphone 100 and reduces the user's comfort.

[0039] In some embodiments, the earphone 100 further includes a battery 14, which powers the loudspeaker 13. When worn, the first end 102 of the housing assembly 10 is closer to the outer ear canal of the user's ear compared to the second end 103. Thus, the loudspeaker 13 can be positioned closer to the first end 102 within the housing assembly 10, while the battery 14 can be positioned closer to the second end 103 within the housing assembly 10. This facilitates the transmission of the airborne sound generated by the loudspeaker 13 to the outer ear canal of the user and ensures the user's ability to hear.

[0040] In some embodiments, the loudspeaker 13 and the battery 14 can be spaced apart from each other in the first direction X within the receiving space 101 formed by the housing assembly 10. In this case, the loudspeaker 13 and the battery 14 can be mounted simultaneously in the housing assembly 10, which can increase assembly efficiency, reduce the length of the connecting wire, and allow the connecting wire to be arranged inside the housing assembly 10 and protected from damage.

[0041] Furthermore, it is provided that a partition wall 104 may be provided in the receiving chamber 101 of the housing arrangement 10, as shown in Fig. Figure 6 shows that the partition 104 can serve to separate the loudspeaker 13 and the battery 14 from each other in order to prevent damage to the loudspeaker 13 in the event of battery 14 leakage or similar occurrences. In some embodiments, the partition 104 can be formed integrally with the housing assembly 10, which can improve the uniformity of the housing assembly 10. In other embodiments, the partition 104 can be formed separately and mounted in the housing assembly 10 by snapping, gluing, or similar means, which can simplify the manufacture of the housing assembly 10. With reference to Fig. 4 and Fig. Figure 5 shows, by way of example, a partition 104 on an inner wall surface LS1 of the housing arrangement 10 facing the user's ear, which adjoins the apex of the arch G1 of the outer wall surface LS2. The loudspeaker 13 is located in a receiving space formed between the partition 104 and the first end 102, while the battery 14 is located in a receiving space formed between the partition 104 and the second end 103.

[0042] In some embodiments, the loudspeaker 13 has a first axis ZX1 and the battery 14 has a second axis ZX2. Both the first axis ZX1 and the second axis ZX2 have a positive direction, which, when worn, points towards the user's ear. In a reference plane defined by the first direction X and the second direction Y, the projections of the positive directions of the first axis ZX1 and the second axis ZX2 onto the reference plane intersect. In other words, the loudspeaker 13 and the battery 14 are arranged at an angle relative to each other. This can increase the space utilization of the housing assembly 10 in the first direction X and ensures that the housing assembly 10 can accommodate individual electronic components without increasing its volume, thus avoiding an excessive size of the housing assembly 10 of the earphone 100 that could impair the user's comfort.The first axis, ZX1, can run parallel to the direction of vibration of a diaphragm of the loudspeaker 13 and through the center of gravity of the loudspeaker 13, the geometric center, or the centroid of the shape of its end surface (e.g., round end surface, track-shaped end surface). The second axis, ZX2, can be an axis that runs through an axis of symmetry of the battery 14 and through the geometric centers or centroids of the shape of its two end surfaces.

[0043] Furthermore, it is provided that, with reference to Fig. 5. The angle of intersection θ between the projections of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 onto the reference plane is an acute angle. To ensure that, with reduced dimensions of the housing assembly 10 in the first direction X, an excessively large tilt angle between the battery 14 and the loudspeaker 13 does not increase the dimensions of the housing assembly 10 in the second direction Y, the angle of intersection θ between the projections of the positive direction of the first axis ZX1 and the positive direction of the second axis ZX2 onto the reference plane can be between 10° and 14° or between 11° and 14°. For example, the angle of intersection 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 intersection angle θ mentioned above.

[0044] In some embodiments, on the reference plane defined by the first direction X and the second direction Y, the radial dimension of the loudspeaker 13 is larger than the radial dimension of the battery 14. The second direction Y has a positive direction, pointing towards the user's ear. The angle of intersection θ1 between the projection of the positive direction of the first axis ZX1 onto the reference plane and the positive direction of the second direction Y is larger than the angle of intersection θ2 between the projection of the positive direction of the second axis ZX2 onto the reference plane and the positive direction of the second direction Y. In some embodiments, the second axis ZX2 can be aligned parallel to the second direction Y, which can facilitate the mounting of the battery 14. In this case, the radial dimension of the loudspeaker 13 can refer to the length of its cross-section through the reference plane in a direction perpendicular to the first axis ZX1.The radial dimension of battery 14 can refer to the length of its cross-section through the reference plane in the direction perpendicular to the second axis ZX2.

[0045] Since the radial dimension of the loudspeaker 13 is larger than the radial dimension of the battery 14, the loudspeaker 13 would occupy a large amount of space in the first direction X if the loudspeaker 13 and the battery 14 were arranged side by side. Therefore, an oblique arrangement of the loudspeaker 13 relative to the second direction Y has a greater effect on changing the length of the projection of the housing arrangement 10 in the first direction X compared to an oblique arrangement of the battery 14 relative to the second direction Y, which ultimately contributes to reducing the length of the housing arrangement 10 in the first direction X.

[0046] The earphone 100 further comprises a printed circuit board 15, which is arranged in the receiving space 101 formed by the housing arrangement 10 and is located on the side of the loudspeaker 13 and the battery 14 facing away from the user's ear. In some embodiments, the number of printed circuit boards 15 can be one, and this is simultaneously connected to a control wire of the battery 14 and the loudspeaker 15. The projection of the printed circuit board 15 in the second direction Y overlaps at least partially with the loudspeaker 13 and the battery 14. Fig. 5. The circuit board 15 can be arranged in the first direction X. This can increase the space utilization and reduce production costs while ensuring the performance of the loudspeaker 13 and the battery 14. In some embodiments, the number of circuit boards 15 can be two, and the two circuit boards are each electrically connected to the battery 14 and the loudspeaker 13, respectively. The axes of the two circuit boards 15 each run parallel to the first axis ZX1 of the loudspeaker 13 and to the second axis ZX2 of the battery 14, respectively. This can further reduce the volume of the housing assembly 10.

[0047] In some embodiments, the housing assembly 10 comprises a first housing 111 and a second housing 112 that fit together along the second direction Y. The loudspeaker 13 and the battery 14 can be attached to the first housing 111, with the first housing 111 being closer to the user's ear than the second housing 112 when worn. The circuit board 15 is attached to the second housing 112. This can facilitate the assembly of the earphone 100 and simplify its disassembly and maintenance. The circuit board 15 can be attached to the second housing 112 of the housing assembly 10 by hot melting. Specifically, the second housing 112 can be provided with multiple fusible links, and the circuit board 15 can be provided with multiple corresponding through-holes.During assembly, the through holes on the circuit board 15 can interact with the fusible links on the second housing 112, after which the circuit board 15 is attached to the second housing by hot melting.

[0048] With reference to Fig. 5 and Fig. The earphone 100 further comprises a charging interface 16 provided on the first housing 111 and a magnetic element 17 located between the battery 14 and the first housing 111 in the direction of the second axis ZX2. The arrangement of the magnetic element 17 between the battery 14 and the first housing 111 enables efficient use of the intake space 101 and increases the space utilization rate. In this case, the earphone 100 can be used together with a charging case 900 with magnetic charging capability.

[0049] With reference to Fig. 9 The charging box 900 can comprise a lower housing assembly 910 and an upper housing assembly 920. The lower housing assembly 910 can be provided with two form-fitting recesses 911 for receiving the earphone 100, and the upper housing assembly 920 can be placed on top of the lower housing assembly 910 to cover the form-fitting recesses 911.

[0050] Furthermore, it is provided that the charging box 900 can include a main control circuit board arranged in the sub-housing arrangement 910 and electrode terminals 912 provided on the main control circuit board.

[0051] The electrode clamps 912 can be provided in several groups, for example, two groups, as required. The electrode clamps 912 can be exposed at the form-fitting recesses 911. When an earphone 100 is placed in the charging case 900, the charging interface 16 of the earphone 100 can be uniquely aligned with the corresponding electrode clamp 912 in the charging case 900 and make contact with the electrode clamp to meet the requirements for functions such as charging and sensing. Accordingly, the electrode clamp 912 can comprise a positive supply clamp and a negative supply clamp and optionally also a test clamp; connecting lines between any two of them can form a triangle, for example, an equilateral triangle, or the clamps can be spaced apart from each other along a straight line, for example, spaced and collinear.

[0052] Additionally, the charging box 900 can include a magnetic structure (not shown) arranged in the lower housing assembly 910. The magnetic structure can be provided in several groups, for example, two groups, as required. After an earphone 100 is inserted into a form-fitting recess 911, the magnetic structure and the magnetic element 17 in the earphone 100 can attract each other and form a magnetic pair, so that the individual charging interface 16 and the respective electrode clamp 912 come into unambiguous contact with each other.

[0053] In the worn state of the earphone 100, it may be necessary for the first end 102 of the housing assembly 10 to protrude into the user's conchae 502. Therefore, if the shape of the outer wall surface LS2 of the first end 102 of the housing assembly 10, facing away from the user's ear, cannot be well adapted to the conchae 502, this may increase the sensation of a foreign body for the user when wearing the earphone 100 and impair the experience.

[0054] In some embodiments, the first direction X has a positive direction pointing from the second end 103 toward the first end 102. An outer wall surface LS3 of the housing assembly 10 facing away from the user's ear can include a first arcuate transition region 105. On the reference plane defined by the first direction X and the second direction Y, the first arcuate transition region 105 gradually approaches the user's ear in the positive direction of the first direction X, thus forming a first part of the first end 102. This design allows the outer surface of the housing assembly 10 to gradually curve toward the user's ear, enabling a better fit to the shape of the cavum conchae 502 and reducing the foreign body sensation for the user when wearing it.

[0055] With reference to Fig. 7 The radius of curvature of the first arc-shaped transition region 105 gradually decreases in the positive direction of the first direction X. In this case, the first arc-shaped transition region has a larger radius of curvature on the side facing away from the user's ear, which can favor the arrangement of internal components in the housing assembly 10.

[0056] With an inclined arrangement of the loudspeaker 13 and the battery 14, an insufficient extension length of the first arcuate transition region 105 in the first direction X could lead to excessive dimensions of a portion of the housing assembly 10 in the thickness direction and reduce the space utilization inside the housing assembly 10. In some embodiments, the extension component L105 of the first arcuate transition region 105 in the first direction X is at least 16 mm. This dimensioning ensures an adequate thickness of the housing assembly 10 at all points and improves the space utilization inside the housing assembly 10.

[0057] As mentioned above, the first end 102 has a first reference point C1 in the first direction X, which is furthest from the second end 103. The first reference point C1 has already been explained above and will not be described further here. At the first reference point C1, the angle α1 between the tangent of the first arcuate transition region 105 and the second direction Y can be between 5 degrees and 8 degrees. For example, the angle α1 between the first arcuate transition region 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, the first arcuate transition region 105 has, with reference to Fig. 7 and Fig. 10 further provides a first mean reference point C4, the distance L14 of which to the first reference point C1 in the first direction X is between 1.8 mm and 3 mm. At the first mean reference point C4, the angle α2 between the tangent of the first arcuate transition region 105 and the second direction Y is between 35° and 53°. In some embodiments, the first arcuate transition region 105 has a second mean reference point C5, the distance L15 of which to the first reference point C1 in the first direction X is between 6 mm and 9 mm. The angle α3 between the tangent of the first arcuate transition region 105 and the second direction Y is between 60° and 80°.

[0058] As described above, by successively restricting the shape of the first arc-shaped transition area 105 at the first reference point C1, the first central reference point C4 and the second central reference point C5, it can be effectively achieved that the first arc-shaped transition area 105 adapts to the shape of the user's cavum conchae 502.

[0059] In some specific embodiments, the distance L14 between the first mean reference point C4 and the first reference point C1 in the first direction X is 2.35 mm. At the first mean reference point C4, the angle α2 between the tangent of the first arcuate transition area 105 and the second direction Y is 43.91 degrees. The distance L14 between the second mean reference point C5 and the first reference point C1 in the first direction X is 7.43 mm. At the second mean reference point C5, the angle α3 between the tangent of the first arcuate transition area 105 and the second direction Y is 70.8 degrees.

[0060] In some embodiments, the side of the housing assembly 10 facing the user's ear has a third reference point C3 in the second direction Y, which is 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 arcuate transition region 106 located between the first reference point C1 and the third reference point C3. The first direction X has a negative direction, pointing from the first end 102 toward the second end 103. In the negative direction of the first direction X, the second arcuate transition region 106 gradually approaches the user's ear, thus forming a second part of the first end 102.Optionally, the radius of curvature of the second arc-shaped transition area 106 gradually increases in the negative direction of the first direction X, and the second arc-shaped transition area simultaneously approaches the user's ear, forming the second part of the first end 102.

[0061] This design allows the shape of the first end 102 to be better adapted to the inner contour of the cavum conchae, in order to reduce the foreign body sensation when the first end 102 penetrates the cavum conchae 502 and to improve the wearing experience for the user.

[0062] In some embodiments, the distance L13 between the third reference point C3 and the first reference point C1 in the first direction X is between 3 mm and 6 mm. Optionally, the angle α4 between the tangent of the second arcuate transition area 106 and the second direction Y at the third reference point C3 is between 75 degrees and 95 degrees.

[0063] In some specific embodiments, the distance L13 between the third reference point C3 and the first reference point C1 in the first direction X is 4.29 mm. At the third reference point C3, the angle α4 between the tangent of the second arcuate transition area 106 and the second direction Y is 84.9°.

[0064] In this way, 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 inclination of the second arcuate transition area 106 in between are each limited, so that the second arcuate transition area 106 can optimally adapt to the interior of the user's caveum conchae 502 and reduce the foreign body sensation.

[0065] Furthermore, the outer wall surface LS2 of the housing assembly 10, facing the user's ear, is provided to include a third arcuate transition area 107, located on the side of the third reference point C3 facing away from the first reference point C1. The third arcuate transition area 107 is curved away from the user's ear. In the first direction X, the distance L10 between the apex G1 of the third arcuate transition area 107 and the first reference point C1 is between 15 mm and 18 mm. In the second direction Y, the distance H10 to the first reference point C1 is between 1 mm and 3 mm.

[0066] In some specific embodiments, the distance L10 between the apex G1 of the third arc-shaped transition area 107 and the first reference point C1 in the first direction X is 17.7 mm. The distance H10 to the first reference point C1 in the second direction Y is 1.91 mm. In this case, when wearing the earphone 100, the apex G1 of the third arc-shaped transition area 107 can be positioned essentially on the outside of the user's tragus 508, which may reduce the likelihood of pressure on the tragus 508.

[0067] As in Fig. As shown in Figure 11, the main module 1 can comprise the housing assembly 10, as described previously. The main module 1 can further include, among other things, the speaker 13 and the battery 14 mentioned above.

[0068] Optionally, as in Fig. As shown in Figure 11, the housing assembly 10 comprises an outer housing 11 and a decorative cover 12. The outer housing 11 has an outer surface that, when worn, faces away from the user's ear. The decorative cover 12 is located on the outer surface OS1 of the outer housing 11 and serves to form a touch positioning area 120 for touch positioning by the user. The main module 1 may further comprise a touch module 18. The touch module 18 may be located on the outer housing 11 and have a touch detection area 182 that overlaps at least partially with the touch positioning area 120. When the user touches a corresponding area on the decorative cover 12, this can be detected by the touch detection area 182.

[0069] The touch positioning area 120 can be used to position the touch detection area 182. Once the user has located the touch positioning area 120, they can essentially recognize that they have reached or are approaching an area available for touch operation. The touch detection area 182 can then detect the user's touch input. The touch module 18 can detect the user's touch input via the touch detection area 182, thus enabling touch recognition and allowing the earphone 100 to implement human-machine interaction functions with the user. For example, functions such as volume control, power on / off, track skipping, play / pause, and operations such as Bluetooth connection / disconnection and switching between Bluetooth devices can be achieved.

[0070] Furthermore, it is provided that a positioning projection 121 may be provided on the outer housing 11 and / or the decorative cover 12. This positioning projection 121 is located within the touch positioning area 120 and protrudes from the outer surface OS1 of the decorative cover 12 facing away from the outer housing 11. By forming the positioning projection 121 protruding from the outer surface OS1 of the decorative cover 12 facing away from the outer housing 11, based on the primary touch navigation and positioning provided by the touch positioning area 120, the user can more easily locate the positioning projection 121 by touching the outer housing 11. This allows the positioning projection 121 to fulfill a secondary touch navigation and positioning function based on the decorative cover 12.This can facilitate more precise positioning of the touch detection area 182 over the positioning protrusion 121 for the user, thus improving the comfort of touch operation. Furthermore, the decorative cover 12 for the earphone 100 can offer unique decorative visual effects. The combination (at least partial overlap) with the touch detection area 182 based on these unique visual effects can eliminate the need for an additional detection area specifically designed for touch, resulting in a reduced volume of the earphone 100. Since the decorative visual effects of the cover 12 can also intuitively guide the user to the position of the touch detection area 182, the user's learning curve is reduced and the comfort of touch operation is improved.

[0071] In some embodiments, the outer surface OS1 of the outer casing 11 and the outer surface OS2 of the decorative cover 12 together form the outer surface OS of the main module 1, as shown in Fig. Figure 11 shows that the outer surface OS of the main module 1 is curved outwards. In other words, the outer surface OS1 of the outer housing 11 and the outer surface OS2 of the decorative cover 12 are both designed with a curved outwards shape. This can increase the horizontal space utilization of the earphone 100 and facilitate the accommodation of other components for the earphone 100 inside the housing assembly 10. Furthermore, the curved outwards shape can visually contribute to a smaller appearance of the main module 1 on the outer surface OS.

[0072] In some embodiments, as in Fig. Figure 11 shows the first direction X and the second direction Y of the housing arrangement 10, which also correspond to the first direction X and the second direction Y of the outer housing 11. The outer housing 11 can have a length direction X, a width direction Z, and a thickness direction Y, all perpendicular to each other. The outer housing 11 is designed to lie flat against the user's ear when stacked in the thickness direction Y when worn. Specifically, the length direction X of the outer housing 11 can be indicated by the arrow X in Fig. 11, the thickness direction Y of the outer casing 11 by the arrow Y in Fig. 11 and the width direction Z of the outer casing 11 by the arrow Z in Fig. Figure 11 is shown. The directions X, Y, and Z are perpendicular to each other.

[0073] In some embodiments, as in Fig. As shown in Figure 12, the ratio of the dimension of the decorative cover 12 to that of the outer casing 11 in the longitudinal direction X is greater than or equal to 0.5 and less than or equal to 0.8. Here, the dimension of the decorative cover 12 in the longitudinal direction X can be determined by the length D in Fig. 12 and the dimension of the outer casing 11 in the longitudinal direction X divided by the length E in Fig. Figure 12 is shown. The following applies: 0.5 ≤ D / E ≤ 0.8. For example, the ratio of the dimension of the decorative cover 12 to that of the outer casing 11 in the longitudinal direction X can be 0.6, 0.7, etc. Preferably, the ratio of the dimension of the decorative cover 12 to that of the outer casing 11 in the longitudinal direction X is greater than or equal to 0.6 and less than or equal to 0.7.

[0074] Optionally, the ratio of the dimension of the decorative cover 12 to that of the outer casing 11 in the width direction Z can be greater than or equal to 0.6 and less than or equal to 0.95. Here, the dimension of the decorative cover 12 in the width direction Z can be divided by the length F. Fig. 12 and the dimension of the outer casing 11 in the width direction Z divided by the length G in Fig. Figure 12 is shown. The following applies: 0.6 ≤ F:G ≤ 0.95. For example, the ratio of the dimension of the decorative cover 12 to that of the outer casing 11 in the width direction Z can be 0.65, 0.75, etc. Optionally, the ratio of the dimension of the decorative cover 12 to that of the outer casing 11 in the width direction Z can be greater than or equal to 0.7 and less than or equal to 0.87.

[0075] By providing this dimensional ratio between the decorative cover 12 and the outer housing 11, the decorative cover 12 can occupy a larger proportion of the outer surface OS1 of the outer housing 11, making it easier for the user to feel the decorative cover 12 when touching the outer surface OS1 of the outer housing 11.

[0076] Of course, in other embodiments, the dimensional ratio between the decorative cover 12 and the outer housing 11 can also assume other values. For example, the ratio of the dimension of the decorative cover 12 to that of the outer housing 11 in the longitudinal direction X could be greater than or equal to 0.3 and less than or equal to 0.8, and the ratio of the dimension of the decorative cover 12 to that of the outer housing 11 in the lateral direction Z could be greater than or equal to 0.4 and less than or equal to 0.9. A more detailed explanation is omitted in the present embodiment.

[0077] In some embodiments, as in Fig. As shown in Figure 12, the positioning projection 121 is strip-shaped, with the extension direction H of the positioning projection 121 intersecting both the longitudinal direction X and the lateral direction Z. The extension direction H of the positioning projection 121 can be indicated by the arrow H in Fig. 12 are shown. This allows the user's hand to receive a distinct tactile sensation when touching through the positioning protrusion that intersects the length direction X and the width direction Z, which facilitates tactile positioning for the user and provides clearer secondary touch navigation and positioning.

[0078] Optionally, the extension direction H of the positioning projection 121 is neither parallel to the longitudinal direction X nor to the lateral direction Z of the outer housing 11 and can intersect the longitudinal direction X of the outer housing 11 at an acute angle. The angle α between the extension direction H of the positioning projection 121 and the longitudinal direction X of the outer housing 11 is given by Fig. 12 shown.

[0079] Optionally, the angle between the extension direction H of the positioning projection 121 and the length direction X of the outer housing 11 can be between 30° and 70°. For example, the angle between the extension direction H of the positioning projection 121 and the length direction X of the outer housing 11 can be 40°, 50°, 60°, etc. This design allows the user to easily detect the positioning projection 121 by touch.

[0080] In some embodiments, the outer casing 11, as in Fig. 12 and Fig. Figure 14 shows a connecting end 103 (hereinafter also referred to as the second end 103) in the longitudinal direction X, which is connected to the ear hook 2, and a free end 102 (hereinafter also referred to as the first end 102) which faces away from the connecting end 103. The outer casing 11 may be curved in the thickness direction Y towards the outer surface OS1 of the outer casing 11. Due to the curve towards the outer surface OS of the outer casing 11, the free end 102 is located closer to the ear opening of the user's ear compared to the connecting end 103, while the decorative cover 12 is positioned closer to the connecting end 103. Since when wearing the earphone 100 on the ear the free end 102 is closer to the ear and the connecting end 103 connected to the ear hook 2 is further away from the ear, arranging the decorative cover 12 closer to the connecting end 103 can make it easier for the user to feel the decorative cover 12.

[0081] In some embodiments, it is provided that, as in Fig. 13 and Fig. As shown in Figure 14, the outer casing 11 can be bent in the thickness direction Y towards the outer surface OS1 of the outer casing 11, such that the free end 102 is closer to the ear opening of the user's ear compared to the connecting end 103. This allows the decorative cover 12 to be positioned as far as possible in an area parallel to the sagittal plane of the human body when the earphone 100 is worn, while reducing the area of ​​the decorative cover 12's bending surface extending towards the ear opening. This facilitates blind operation and quick positioning of the positioning projection 121 for the user.

[0082] In some embodiments, it is provided that, as in Fig. As shown in Figure 13, the free end 102 can have a first reference position K1 in the longitudinal direction X, which is furthest from the connecting end 103, and the decorative cover 12 can have a second reference position K2, which is closest to the first reference position K1 in the longitudinal direction X. The free end 102 can, in the worn state, project at least partially into the cavum conchae 502.

[0083] The outer casing 11 features an arc-shaped transition area 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 area 114 gradually approaches the user's ear in the thickness direction Y when worn. Therefore, the portion of the earphone 100 corresponding to the arc-shaped transition area 114 can gradually move closer to the user's ear in the thickness direction Y when the earphone 100 is worn, or even lie against the user's ear, allowing the free end 102 to protrude more easily into the conchal cavity 502. This can improve the wearing comfort and stability of the earphone 100. Furthermore, starting from the position of the second reference point K2 of the decorative cover 12, the arc-shaped transition area 114 gradually curves towards the first reference position K1.Using the second reference position K2 as a turning point, the user can more effectively locate the decorative cover 12 and thus the touch positioning area 120, which improves the ease of touch operation. The edge of the decorative cover 12 is located close to the curved separation point of the outer housing 11, which facilitates the detection and positioning of the decorative cover 12 for the user when operating it blindly.

[0084] 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 housing 11. This allows the user to perceive a tactile difference when touching the decorative cover 12 and the outer surface OS1 of the outer housing 11 due to the different roughness, thus making it easy to distinguish between the decorative cover 12 and the outer housing 11. This can facilitate the user's positioning of the touch detection area 182 for the touch and increase the comfort of the touch.

[0085] In some embodiments, the color of the outer surface OS2 of the decorative cover 12 differs from the color of the outer surface OS1 of the outer housing 11. For example, the outer surface OS2 of the decorative cover 12 can be red, blue, etc., while the outer surface OS1 of the outer housing 11 can be white, black, etc., to allow the user to visually distinguish between the decorative cover 12 and the outer housing 11. The different coloring of the outer surface OS2 of the decorative cover 12 and the outer surface OS1 of the outer housing 11 can create a color difference on the outer surface OS of the main module 1, which can visually contribute to a smaller appearance of the entire main module 1, thereby improving the aesthetic effect of the earphone 100 and achieving visual miniaturization.In addition, the color difference of the decorative cover 12 allows for a clear localization of the touch detection area 182, which can make it easier for the user to find the touch detection area 182, reduce the learning curve and increase touch efficiency.

[0086] In some embodiments, the material of the decorative cover 12 can differ from that of the outer casing 11. For example, the decorative cover 12 can be made of a transparent acrylic sheet, while the outer casing 11 can be made of metal. Alternatively, the decorative cover 12 can be made of metal and the outer casing 11 of plastic, resin, or similar materials. The material difference between the decorative cover 12 and the outer casing 11 can not only make it easier for the user to distinguish between them, but also enhances the decorative effect of the decorative cover 12. Additionally, the material difference can offer the user differentiated haptic textures, further simplifying touch operation and increasing user comfort.

[0087] In some embodiments, at least part of the edge of the decorative cover 12 may be exposed on the outer surface OS1 of the outer housing 11 in order to enclose the touch positioning area 120, as shown in Fig. Figure 14 shows that the touch positioning area 120 can be enclosed by at least the portion of the edge of the decorative cover 12 exposed on the outer surface OS1 of the outer housing 11. When the user performs touch operation on the outer surface OS1 of the outer housing 11, they can feel at least this portion of the edge of the decorative cover 12. Because the edge can provide tactile feedback for the user, the user clearly recognizes that they have touched the corresponding area, which effectively aids navigation and positioning.

[0088] Optionally, the edge of the decorative cover 12 can be ring-shaped and fully exposed on the outer surface OS1 of the outer housing 11 to enclose the touch positioning area 120. The edge of the decorative cover 12 surrounds the positioning protrusion 121. In other words, the user can feel the entire edge of the decorative cover 12 because the entire edge of the decorative cover 12 is exposed on the outer surface OS1 of the outer housing 11, which improves positioning and further increases touch efficiency for the user. Furthermore, the positioning protrusion 121 is positioned in the center of the decorative cover 12 and not near the edge of the decorative cover 12. This ensures a more stable position of the positioning protrusion 121 and largely prevents it from detaching from the touch positioning area 120 enclosed by the decorative cover 12.

[0089] In some embodiments, the outer housing 11 may be provided on the outside with a positioning recess 113, as shown in Fig. 14 shown. The decorative cover 12 is attached over the recess opening of the positioning recess 113 in the positioning recess 113.

[0090] Optionally, the shape and size of the positioning recess 113 and the decorative cover 12 can be matched to facilitate the installation of the decorative cover 12 in the positioning recess 113 of the outer housing 11 and to achieve a more uniform joint between the two components, providing a finer and softer tactile feel.

[0091] Optionally, the joint between the edge of the decorative cover 12 and the edge of the recess opening of the positioning recess 113 is exposed on the outside, and the joint surrounds the positioning projection 121. The joint formed between the edge of the decorative cover 12 and the edge of the positioning recess 113 can create a significant tactile contrast to other areas. By feeling this joint, the user can quickly and effectively recognize that they have located the corresponding area, which can increase touch efficiency for the user.

[0092] In some embodiments, the positioning projection 121 can protrude from the outer surface OS1 of the outer housing 11, and the decorative cover 12 is provided with a positioning hole 122 through which the positioning projection 121 passes. The positioning hole 122 and the positioning projection 121 allow for precise mounting of the decorative cover 12 and the outer surface OS1 of the outer housing 11, enabling more accurate positioning of the touch detection area 182. Furthermore, the interaction of the positioning recess 113 and the positioning projection 121 further increases the mounting accuracy of the decorative cover 12 and the outer housing 11. This allows for more precise positioning of the touch detection area 182 by the touch positioning area 120, thus improving the precision and comfort of the touch functionality.

[0093] Optionally, the positioning projection 121 can protrude from the outer surface OS2 of the decorative cover 12 and be integrally formed with the decorative cover 12. This can ensure greater stability of the positioning projection 121, largely prevent it from detaching from the decorative cover 12, and guarantee a fixed position of the positioning projection 121 and the touch positioning area 120 relative to each other. This allows the user to be offered both primary and secondary touch navigation and positioning, characterized by high precision.

[0094] Optionally, at least two sound-receiving holes 115 can be formed in the outer surface OS of the main module 1. The two sound-receiving holes 115 can each be located on two opposite inclined surfaces of the outer surface OS of the main module 1. By providing the two sound-receiving holes 115 on two opposite inclined surfaces, the two sound-receiving holes 115 point in different directions, which can extend the sound-receiving area of ​​the earphone 100. The different orientation can also reduce mutual interference between the two sound-receiving holes 115.

[0095] In some embodiments, the positioning projection 121 can be strip-shaped, with the two sound receiving holes 115 located on opposite sides of the positioning projection 121. By providing the two sound receiving holes 115 on both sides of the positioning projection 121, mutual interference between the two sound receiving holes 115 can be reduced.

[0096] The positional relationship between the touch detection area 182 and the positioning projection 121 can be designed in various ways.

[0097] First option: Optionally, the touch detection area 182 can surround the positioning protrusion 121, allowing the user to precisely locate and confirm the position of the touch detection area 182 by feeling the positioning protrusion 121. This allows the user to quickly and accurately locate the position of the touch detection area 182 when using the earphone 100, which can optimize the user experience.

[0098] Second option: The touch detection area 182 can be positioned closer to the connection end 103 compared to the positioning projection 121 to facilitate sensor-based triggering of the touch detection area 182 by the user. Alternatively, the touch detection area 182 can surround the positioning projection 121 to facilitate precise positioning of the touch detection area 182 and triggering of the touch module 18 via the positioning projection 121 for the user.

[0099] In some embodiments, the touch module 18 may comprise a touch metal pattern 181 and a printed circuit board 15, as shown in Fig. Figures 15 to 16 are shown. The circuit board 15 can be arranged inside the outer housing 11. The touch metal pattern 181 can be arranged inside the outer housing 11 or clamped between the decorative cover 12 and the outer housing 11. The touch metal pattern 181 is electrically connected to the circuit board 15. The touch metal pattern 181 serves to form the touch detection area 182.

[0100] When the user touches and / or presses the touch positioning area 120 or the positioning protrusion 121, the touch metal pattern 181, which forms the touch detection area 182, can be sensorily triggered. The touch metal pattern 181 can then generate corresponding signals and transmit them to the circuit board 15 to trigger further functional responses.

[0101] In some embodiments, the touch metal pattern 181 can also be configured as a radio frequency antenna for the earphone 100. The earphone 100 can receive and transmit RF (radio frequency) signals via the touch metal pattern 181, thereby extending the functionality of the earphone 100 to enable information exchange between the earphone 100 and other devices.

[0102] Naturally, the number of sound pickup holes 115 can be at least one. The single sound pickup hole 115 penetrates at least the outer housing 11 and connects the environment to the pickup chamber 101. Accordingly, the main module 1 can also include a microphone 19. The microphone 19 is located in the pickup chamber 101 and positioned correspondingly to the sound pickup hole 115 in order to pick up sound from the environment via the sound pickup hole 115.

[0103] Optionally, the main module 1 can be used, as in Fig. Figures 17 to 20 show that the main module 1 may be provided with at least two sound-receiving holes 115 connecting the recording chamber 101 to the environment. The main module 1 may further comprise at least two microphones 19. The at least two microphones 19 are spaced apart from one another within the recording chamber 101 and are uniquely positioned corresponding to the at least two sound-receiving holes 115. For example, with two microphones 19, one of the sound-receiving holes 115 may penetrate the outer casing 11 and be located on the outer perimeter of the decorative cover 12. The other sound-receiving hole 115 may penetrate both the outer casing 11 and the decorative cover 12; that is, the sound-receiving hole 115 is located within the area enclosed by the edge of the decorative cover 12. Accordingly, two microphones 19 may be provided in the recording chamber 101, uniquely positioned corresponding to the two sound-receiving holes 115.

[0104] By providing at least two sound-receiving holes 115, the sound-receiving area can be extended and the sound-receiving quality improved. Furthermore, the probability that both sound-receiving holes will be blocked simultaneously when the decorative cover 12 is touched can be reduced by placing one of the holes inside the decorative cover 12 and the other hole outside of the decorative cover 12. This reduces the impact on the sound-receiving effect.

[0105] Optionally, using the example of two sound pickup holes 115, the distance between the two sound pickup holes 115 is greater than or equal to the dimension of the decorative cover 12 in the arrangement direction of the two microphones 19. Since one of the sound pickup holes is located outside the decorative cover 12, the other can be positioned as close as possible to the edge of the decorative cover 12 to ensure a greater distance between the two sound pickup holes 115.When the touch positioning area 120 of the decoration cover 12 is touched, it is largely prevented that the sound reception hole 115 located outside the decoration cover 12 and the sound reception hole 115 located near the edge of the decoration cover 12 are blocked, which further reduces the probability of both sound reception holes 115 being blocked simultaneously when the decoration cover 12 is touched and thus reduces the influence on the sound reception effect.

[0106] Optional, as in Fig. Figure 17 shows the touch positioning area 120 positioned between the two sound reception holes 115. This makes it more difficult to block both sound reception holes 115 when the touch positioning area 120 is touched and thus reduces the influence on the sound reception effect.

[0107] Optionally, the arrangement direction of the two sound-receiving holes 115 intersects the longitudinal direction X and the lateral direction Z of the outer housing 11. The sound-receiving hole 115 passing through the decorative cover 12 (i.e., the sound-receiving hole 115 located within the area enclosed by the edge of the decorative cover 12) is, compared to the sound-receiving hole 115 positioned on the outer circumference of the decorative cover 12, closer to the connecting end 103 and closer to the edge of the decorative cover 12, which is further away from the ear hook 2 in the lateral direction Z.By arranging the sound pickup hole 115 "lower left", it is possible, on the one hand, to position the sound pickup hole 115, which passes through the decorative cover 12, closer to the user's mouth and the loudspeaker 13. This enables clear recording of the user's voice and the sound from the loudspeaker 13, facilitates noise reduction, and improves the sound pickup quality from the environment. On the other hand, the likelihood of the sound pickup hole 115 being blocked when the decorative cover 12 is touched can be reduced by positioning the sound pickup hole 115 closer to the edge of the decorative cover 12 that is further away from the ear hook 2 in the lateral direction Z.

[0108] Optionally, the main module 1 can be used, as in Fig. Figures 18 to 20 show a sealing arrangement 190. At least part of the sealing arrangement 190 is positioned between the outer housing 11 and the microphone 19 to separate a sound recording channel from the recording chamber 101. This ensures that the sound recording channel is sealed off from other areas of the recording chamber 101 outside the sound recording channel and reduces the influence of dust, moisture, etc., ingress through the sound recording holes 115 into the sound recording channel on other electrical components within the recording chamber 101.

[0109] Optionally, the main module 1 can also include a mounting plate for fixing the microphone 19. Optionally, the mounting plate can be the circuit board 15. Alternatively, in other embodiments, the mounting plate can also be a plate-shaped component other than the circuit board 15 or a part of the housing assembly 10 and serve to fix the microphone 19 and optionally also to fix other components.

[0110] As in Fig. As shown in Figures 18 to 20, the mounting plate is located in the receiving chamber 101 and is provided with a through-hole 151. The microphone 19 is attached to one side of the mounting plate and covers the through-hole 151. At least part of the sealing assembly 190 is located in the receiving chamber 101, rests against the outer housing 11 and against a side of the mounting plate facing away from the microphone 19, and brings the through-hole 151 and the sound receiving hole 115 into communication with each other. This can improve the mounting stability and sealing of the sealing assembly 190.

[0111] Various options are available for designing the interaction of the sealing arrangement 190 with the outer housing 11 etc., and a targeted design depending on the mounting structure or the position of the microphone 19 is conceivable.

[0112] In some embodiments, the construction of the sealing arrangement 190 and its associated description are explained by way of example as follows for the sound receiving hole 115 which penetrates the outer housing 11 and is located on the outer circumference of the decorative cover 12: As in Fig. 18 and Fig. As shown in Figure 19, the microphone 19 can penetrate the outer housing 11 and be located on the outer circumference of the decorative cover 12. The sealing arrangement 190 can comprise a rubber sealing ring 191a and a gauze arrangement 192a. The rubber sealing ring 191a and the gauze arrangement 192a are arranged one above the other, and both are located in the receiving chamber 101 and are situated between the mounting plate and the outer housing 11. Since the microphone 19 is located on the outer circumference of the decorative cover 12 and penetrates the outer housing 11, the outer housing 11 exhibits good integrity and uniformity in this case. Therefore, the superimposed arrangement of the rubber sealing ring 191a and the gauze arrangement 192a between the mounting plate and the outer housing 11 enables, on the one hand, a better sealing effect with good uniformity by means of the outer housing 11.On the other hand, the superimposed arrangement of the rubber sealing ring 191a and the gauze arrangement 192a can create a thicker sealing arrangement 190, which more tightly seals the gap between the outer housing 11 and the mounting plate. The gauze arrangement 192a can also reduce the ingress of dust and contaminants into the receiving chamber 101, thus further improving the sealing effect.

[0113] Optionally, the rubber sealing ring 191a is stacked against the mounting plate and is located closer to the through-hole 151 compared to the gauze assembly 192a. The gauze assembly 192a is located between the rubber sealing ring 191a and the outer housing 11 and is closer to the sound pickup hole 115 compared to the rubber sealing ring 191a. Thus, the gauze assembly 192a is positioned further forward (i.e., closer to the sound pickup hole 115) compared to the rubber sealing ring 191a, which can reduce the ingress and accumulation of dust and contaminants on the rubber sealing ring 191a. This allows dust, contaminants, and moisture to be prevented from entering the pickup chamber 101 earlier and more effectively.

[0114] In some other embodiments, the construction of the sealing arrangement 190 and its associated description are explained by way of example as follows for the sound receiving hole 115 which penetrates both the outer housing 11 and the decorative cover 12: As in Fig. As shown in Figure 20, the microphone 19 can penetrate both the outer housing 11 and the decorative cover 12. The sealing arrangement 190 can comprise a rubber sealing ring 191b and at least one gauze arrangement 192b. The rubber sealing ring 191b is located in the recording chamber 101 and is situated between the outer housing 11 and the mounting plate, being pressed directly against the outer housing 11 and the mounting plate. The at least one gauze arrangement 192b is arranged between the outer housing 11 and the decorative cover 12.Since the fit between the decorative cover 12 and the outer housing 11, as well as between the sealing assembly 190 and the mounting plate, tends to involve larger errors, the connection of the more deformable rubber sealing ring 191b to the mounting plate enables a reduction in the fit errors between the decorative cover 12 and the outer housing 11, as well as between the sealing assembly 190 and the mounting plate. This ensures the sealing effect for circuit components.

[0115] Optionally, the number of at least one gauze assembly 192b can be two. One of the gauze assemblies 192b is arranged between the outer housing 11 and the decorative cover 12, while the other gauze assembly 192b and the rubber sealing ring 191b are arranged one above the other in the receiving chamber 101 and are located between the outer housing 11 and the mounting plate.

[0116] By arranging the gauze assembly 192b between the outer housing 11 and the decorative cover 12, the ingress of dust, contaminants, and moisture into the receiving chamber 101 can be reduced. Furthermore, the gauze assembly 192b between the outer housing 11 and the decorative cover 12 can seal the sound receiving hole 115, thus reducing the ingress of moisture through the sound receiving hole into the gap between the outer housing 11 and the decorative cover 12 and the resulting impairment of the connection stability between the two components. The sealing effect is further improved by arranging the rubber sealing ring 191b in the receiving chamber 101 and sealing it between the outer housing 11 and the mounting plate. This reduces the risk of moisture entering the receiving chamber 101 through the sound receiving hole 115 and affecting other electrical components.

[0117] The construction of the above-mentioned gauze arrangements 192a and 192b is described below by way of example: As in Fig. As shown in Figures 19 to 20, the gauze arrangements 192a and 192b each comprise an annular double-sided adhesive tape 1921 and a gauze 1922. The annular double-sided adhesive tape 1921 and the gauze 1922 are arranged one above the other, and the annular double-sided adhesive tape is adhered to the gauze 1922. Specifically, one side of the annular double-sided adhesive tape 1921 can be adhered to the gauze 1922, while the other side can be connected to the outer casing 11 or the decorative cover 12 located close to the tape. For example, for the sound-receiving hole 115, which penetrates both the outer casing 11 and the decorative cover 12, one side of the annular double-sided adhesive tape 1921 can be adhered to the gauze 1922 and the other side to the outer casing 11.For the sound-receiving hole 115, which penetrates the outer casing 11 and is located on the outer circumference of the decorative cover 12, one side of the annular double-sided adhesive tape 1921 can be adhered to the gauze 1922 and the other side to the outer casing 11. The gauze 1922 can be arranged according to the sound-receiving hole 115 and the through-hole 151 to effectively reduce the ingress of contaminants and dust into the recording chamber 101. Specifically, the annular double-sided adhesive tape 1921 surrounds the outer circumference of the sound-receiving hole 115, while the portion of the gauze 1922 located in the center of the annular double-sided adhesive tape 1921 is positioned according to the sound-receiving hole 115.

[0118] Optionally, the number of ring-shaped double-sided adhesive tapes 1921 is two, and the number of gauze 1922 is one. The gauze 1922 is stacked and glued between the two ring-shaped double-sided adhesive tapes 1921. Providing the two ring-shaped double-sided adhesive tapes 1921 increases the adhesive strength of the gauze 1922 and improves its fixation. It also increases the thickness, resulting in a tighter seal of the gap between the outer casing 11 and the decorative cover 12, or between the outer casing 11 and the rubber sealing rings 191a, 191b, thus improving the sealing effect.

[0119] Optionally, the number of ring-shaped double-sided adhesive tapes 1921 and the number of gauzes 1922 are two. The two ring-shaped double-sided adhesive tapes 1921 are spaced apart. One of the gauzes 1922 is glued on top of the other two ring-shaped double-sided adhesive tapes 1921, and the other ring-shaped double-sided adhesive tape 1921 is stacked between the two gauzes 1922. The use of two gauzes 1922 further enhances filtering and separation effects. The use of the two ring-shaped double-sided adhesive tapes 1921 allows for effective fixation of the two gauzes 1922 and also increases their thickness, resulting in a tighter seal of the gap between the outer casing 11 and the decorative cover 12 or between the outer casing 11 and the rubber sealing rings 191a, 191b, thus further improving the sealing effect.

[0120] With reference to Fig. As mentioned above in sections 21 to 23, the earphone 100 can comprise the housing assembly 10 and the loudspeaker 13. Optionally, the earphone 100 can also include a sealant (not marked). The housing assembly 10 serves to form a first receiving chamber 1011. The loudspeaker 13 comprises a basket 131 and a metal welding tab 132. With reference to Fig. 24 and Fig. 25 The basket 131 is arranged in the first recording chamber 1011. The metal welding tab 132 is arranged on the basket 131 and on a side facing the battery 14 to ensure the electrical connection of the loudspeaker 13 with other elements. The sealant seals the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first recording chamber 1011.

[0121] By sealing the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011 with the sealant, a seal between the loudspeaker 13 and the housing can be achieved, which improves the tightness of the housing arrangement 10 and reduces the risk of damage to electronic elements by water ingress.

[0122] During the application of the sealant, it must typically be applied around the basket 131 so that the sealant continuously fills the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011, thus achieving a stable and reliable seal between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011. In the prior art, the metal weld tab 132 is generally designed to extend from the basket 131 beyond the inner circumferential wall of the first receiving chamber 1011 to establish a connection with a power source outside the first receiving chamber 1011. During the sealant application, the weld tab significantly obscures the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011, making it difficult to apply the sealant near the weld tab.This creates the risk that the sealant will be interrupted at the weld tab, reducing the sealing reliability.

[0123] By positioning the metal welding tab 132 on the side of the inner circumferential wall of the first receiving chamber 1011 facing the battery 14, and by maintaining a certain distance between the metal welding tab 132 and the inner circumferential wall of the first receiving chamber 1011, the space between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011 in the area of ​​the welding tab can be exposed to the outside during the application of the adhesive. This facilitates the application of the adhesive in the area of ​​the welding tab and promotes the continuous filling of the space between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011 with sealant to achieve a stable and reliable seal.

[0124] Furthermore, it is provided that a conductor wire 133 can extend from the metal welding tab 132 to the inner circumferential wall of the first receiving chamber 1011. The diameter of the conductor wire 133 is significantly smaller than the dimensions of the metal welding tab 132. The conductor wire 133 only minimally covers the space between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011, which facilitates the application of the adhesive and contributes to a stable and reliable sealing effect.

[0125] With reference to Fig. In some embodiments, the metal welding tab 132 is designed in such a way that it does not extend beyond the outer circumferential wall of the basket 131, as shown in figures 23 to 25.

[0126] This prevents the metal welding tab 132 from covering the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011 during the adhesive application. This facilitates the adhesive application and contributes to a stable and reliable sealing effect.

[0127] With reference to Fig. 23, Fig. 24 and Fig. 26 In some embodiments, the metal welding tab 132 extends beyond the outer circumferential wall of the basket 131, wherein the projection S1 of the metal welding tab 132 relative to the outer circumferential wall of the basket 131 is not greater than half the dimension of the space S2 between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011.

[0128] This ensures that the metal welding tab 132 does not completely cover the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011 during adhesive application, thus allowing adhesive application in the area of ​​the welding tab 132. By limiting the projection S1 of the metal welding tab 132 relative to the outer circumferential wall of the basket 131 to a maximum of half the dimension of the gap S2 between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011, the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011 in the area of ​​the welding tab can be partially exposed to the outside during adhesive application.Since the sealant exhibits a certain degree of flowability during application, this flowability can be used to completely fill the gap between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011, thus achieving a stable and reliable seal. For example, the projection S1 of the metal welding tab 132 relative to the outer circumferential wall of the basket 131 can be set to 0.2 to 0.3 times or 0.4 to 0.5 times the dimension of the gap S2 between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011.

[0129] In some embodiments, the first receiving chamber 1011 has, with reference to Fig. 23, Fig. 27 and Fig. 28 an open end 1014. The basket 131 is inserted into the first receiving chamber 1011 via the open end 1014. The metal weld tab 132 is located on the side of the basket 131 facing the open end 1014. The earphone 100 also includes a conductor wire 133, which conductor wire 133 is welded to the side of the metal weld tab 132 facing the open end 1014.

[0130] During the assembly of the basket 131, the circumferential side of the basket 131 and the side of the basket 131 facing away from the open end 1014 come into contact with the inner wall of the first receiving chamber 1011. By arranging the metal welding tab 132 on the side of the basket 131 facing the open end 1014 and welding the conductor wire 133 to the side of the metal welding tab 132 facing the open end 1014, reduced disturbances to the assembly process caused by the metal welding tab 132 and the conductor wire 133, and increased assembly efficiency, can be achieved.

[0131] With reference to Fig. 23 to 25 In some embodiments, the sealing adhesive is applied via the open end 1014 into the space between the outer circumferential wall of the basket 131 and the inner circumferential wall of the first receiving chamber 1011.

[0132] During adhesive application, the space between the outer perimeter wall of the basket 131 and the inner perimeter wall of the first receiving chamber 1011 can be exposed to the outside via the open end 1014. This facilitates the application of adhesive from the outside through the open end 1014 into the space between the outer perimeter wall of the basket 131 and the inner perimeter wall of the first receiving chamber 1011, allowing the sealant to enter the space between the outer perimeter wall of the basket 131 and the inner perimeter wall of the first receiving chamber 1011 via the open end 1014. This simplifies the adhesive application and increases assembly efficiency.

[0133] With reference to Fig. In some embodiments, the earphone 100, as described in figures 27 to 29, further comprises a carrier 134. The basket 131 is provided with an annular support surface 1311, which faces the open end 1014, and a mounting support surface 1312. The annular support surface 1311 extends along the circumference of the basket 131 and is provided with a first recess 1313. The mounting support surface 1312 corresponds to the position of the first recess 1313 along the circumference of the basket 131. The metal welding tab 132 is arranged on the mounting support surface 1312, and the carrier 134 rests against the annular support surface 1311.

[0134] The mounting support surface 1312 can be recessed in the area of ​​the first recess 1313 relative to the annular support surface 1311, away from the open end 1014. The metal welding tab 132 typically protrudes to a certain height. Because the annular support surface 1311 is provided with the first recess 1313, the support 134, when supported on the annular support surface 1311, can move away from the metal welding tab 132 and the conductor wire 133, thus facilitating the mounting of the support 134 to the cage 131 and increasing assembly efficiency.

[0135] In some embodiments, the end of the support 134 facing the basket 131 is described with reference to Fig. 28 and Fig. 29 is provided with a second recess 1341. The second recess 1341 corresponds along the circumference of the basket 131 to the position of the mounting support surface 1312.

[0136] By providing the second recess 1341, the support 134 can more easily avoid the metal welding tab 132 and the conductor wire 133 when it is supported on the ring-shaped support surface 1311, which simplifies the mounting of the support 134 on the basket 131 and increases assembly efficiency.

[0137] In some embodiments, the housing arrangement 10 forms, with reference to Fig. 22 to 24 further includes a second recording chamber 1012. The housing assembly 10 comprises a partition 104 for separating the first recording chamber 1011 and the second recording chamber 1012. The earphone 100 also includes a battery 14, which is arranged in the second recording chamber 1012. The metal welding tab 132 is located on one side of the basket 131 facing the partition 104.

[0138] Part of the inner perimeter wall of the first recording chamber 1011 can be formed by the partition 104. Part of the sealant can seal the gap between the outer perimeter wall of the basket 131 and the partition 104. By providing the partition 104, the risk of water entering the second recording chamber 1012 from the side of the loudspeaker 13 located near the sound outlet 1013 can be reduced.

[0139] The battery 14 can serve as a power source to supply the loudspeaker 13 with current. The adjacent arrangement of the first recording chamber 1011 and the second recording chamber 1012 facilitates the simplification of the connecting lines between the battery 14 and the loudspeaker 13. By positioning the metal welding tab 132 on the side of the basket 131 facing the partition 104, the distance between the battery 14 and the metal welding tab 132 can be reduced, which is advantageous for further simplifying the connecting lines between the battery 14 and the loudspeaker 13. Furthermore, it is provided that the metal welding tab 132 can be connected to the battery 14 via the conductor wire 133 in order to supply the loudspeaker 13 with current from the battery 14.

[0140] So far, only some embodiments of the present application have been explained, without limiting the scope of protection of the present application. Any equivalent device or process modifications made on the basis of the description and the accompanying drawing of the present application, or direct or indirect applications in other affected fields, should also be covered by the scope of protection of the present application.
