[0059] As described in the background technology, the earphones in the related art will squeeze the wearer's tragus, reducing the wearing comfort of the earphones. In view of the above technical problems, the embodiment of the present application provides an earphone, including a main body, an extension connected to the main body, and a sound-generating part connected to the extension; in the wearing state, the end of the main body away from the extension extends downward along the back side of the ear, the end of the extension away from the main body bypasses the top of the helix of the ear and extends toward the concha cavity of the ear, and the sound-generating part is located in the concha cavity of the ear; the extension includes an inner surface facing the concha cavity, an outer surface facing the outside of the human body, an outer side facing the tragus, and an inner side facing the helix, and the inner surface of the extension gradually tilts toward the direction of the ear hook plane from the inner side to the outer side; wherein the ear hook plane is a plane tangent to the back of the earphone or a sagittal plane of the human body. In this way, by tilting the inner surface of the extension relative to the direction of the ear hook plane, there is a gap between the inner surface of the extension and the tragus in the direction perpendicular to the ear hook plane, which can reduce the squeezing and contact of the wearer's tragus and helix foot, thereby improving the wearing comfort of the earphone.

[0060] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0061] In order to facilitate a clear description of the structure of the earphones provided in the present application, the structure of the ear and the wearing state involved in the text, the front, back, upper and lower sides of the ear, the sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, vertical axis of the human body, and the definitions of X, Y, and Z directions will be explained below.

[0062] Please refer to the attached Figure 1The ear 200 of the user may include structures such as a helix 210, a suprastragal notch 213, a concha 220, a tragus 230, an antitragus 240, an antihelix 250, an antihelix crus 251, an antihelix crus 252, a triangular fossa 260, a helix crus 270, an ear canal opening 280, and an earlobe 290. The concha 220 may include a cymba concha 222 and a concha cavity 221.

[0063] The “front side of the ear” mentioned in this application is a concept relative to the “back side of the ear”. The former refers to the side of the ear away from the head, and the latter refers to the side of the ear facing the head. The “upper edge of the ear” refers to the outer edge of the ear's helix facing upward, and the “lower edge of the ear” refers to the outer edge of the ear's helix facing downward. They are both aimed at the user's ear.

[0064] The sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, and vertical axis of the human body are defined as follows: As is well known, in the fields of medicine and anatomy, three basic planes of the human body, namely the sagittal plane, coronal plane, and horizontal plane, and three basic axes, namely the sagittal axis, coronal axis, and vertical axis, can be defined. Among them, the sagittal plane refers to a plane perpendicular to the ground along the front-back direction of the body, which divides the human body into left and right parts; the coronal plane refers to a plane perpendicular to the ground along the left-right direction of the body, which divides the human body into front and back parts; the horizontal plane refers to a plane parallel to the ground along the up-down direction of the body, which divides the human body into upper and lower parts. Accordingly, the sagittal axis refers to an axis perpendicular to the coronal plane along the front-back direction of the body, the coronal axis refers to an axis perpendicular to the sagittal plane along the left-right direction of the body, and the vertical axis refers to an axis perpendicular to the horizontal plane along the up-down direction of the body.

[0065] The definitions of X, Y, and Z directions are as follows: Figure 2 , taking the center of the ear canal opening 280 as the origin, establish a coordinate system. The direction pointing to the back of the ear and parallel to the sagittal axis is defined as the positive direction of the X axis; the direction pointing to the outside of the ear and parallel to the coronal axis is defined as the positive direction of the Y axis (i.e., the positive direction of the Y axis). Figures 3 to 6 The direction pointing outward from the paper surface) is defined as the positive direction of the Z axis, which is parallel to the vertical axis and points to the top of the ear. It should be noted that the above direction definitions are only for the convenience of description. In accordance with the principle of the technical solution, the X, Y, and Z directions can be defined arbitrarily, including but not limited to the axial symmetry and angular symmetry of the above directions.

[0066] In order to facilitate the understanding and description of the shape of the earphones in a non-worn state or a worn state, the earphones can be projected onto a specific plane, and the earphones can be described by parameters related to the projection shape of the earphones on the specific plane. In the worn state, the earphones can be projected onto the sagittal plane of the human body to form a corresponding projection shape. In the non-worn state, the earphones can be projected onto the earhook plane to form a corresponding projection shape. The earhook plane can be determined as follows: place the earphones horizontally on a plane so that the back of the earphones fits into the plane. The plane tangent to the back of the earphones can be used as the earhook plane. It is easy to understand that the plane tangent to the back of the earphones includes the plane tangent to most areas of the back of the earphones. Please refer to the attached Figure 7 , the ear hook plane 300 is tangent to the back of the earphone, and there is a tangent point. In some embodiments, the ear hook plane and the human body sagittal plane may have a certain angle, such as between 10° and 30°, and the earphone projected on the human body sagittal plane and the ear hook plane may form a similar projection shape; of course, in some embodiments, the ear hook plane is parallel to the human body sagittal plane, and the earphone projected on the human body sagittal plane and the ear hook plane may form the same projection shape, so the human body sagittal plane may also be regarded as the ear hook plane.

[0067] Please refer to the attached Figure 4 , Attachment Fig. 9 To Attachment Fig.12 The earphone 100 includes a main body 110, an extension 120 and a sound-emitting part 130, and the main body 110 is connected to the extension 120. One end of the main body 110 is a connecting end, and the other end is a free end, and the connecting end of the main body 110 is used to connect with the extension 120. The main body 110 is used to be hung on the back side of the ear, and can be balanced with the extension 120 and the sound-emitting part 130, so that the earphone 100 can be better worn on the ear 200. In the wearing state, the free end of the main body can also be against the back side of the ear, such as the ear root, earlobe, the head position behind the ear root, etc., so as to support the wearing of the earphone and facilitate the earphone to be stably worn on the ear. In some embodiments, the free end of the main body can be provided with a battery for powering the earphone, and can also be provided with electronic components such as an antenna and Bluetooth for communicating with other devices.

[0068] For the convenience of description, in some embodiments, in the wearing state, the ear root contact area on the earphone that contacts the ear root can be used as a boundary to divide the extension portion 120 and the main body 110. In short, in the wearing state, the main body 110 is mainly located at the rear side of the ear, and the extension portion 120 is mainly located at the front side of the ear 200, so that the earphone 100 can be hung on the helix of the ear 200. In some embodiments, the part with the smallest cross-sectional area on the earphone can also be used as a boundary, in other words, along the direction of the earphone, the thinnest part of the earphone is used as a boundary to divide the main body 110 and the extension portion 120.

[0069] Please refer to the attached Figure 4 To Attachment Figure 6 In the wearing state, the end of the main body 110 away from the extension part 120 extends downward along the back side of the ear, and the end of the extension part 120 away from the main body 110 bypasses the top of the helix of the ear 200 and extends toward the concha cavity of the ear. In other words, the main body 110 and the extension part 120 are respectively located at the front and back sides of the ear, so that the earphone 100 is hung on the helix of the ear 200. Among them, the sound-emitting part 130 is located in the concha cavity of the ear, so that the sound-emitting part 130 is closer to the ear canal opening, which improves the sound quality of the earphone.

[0070] In some embodiments, the shape of the extension portion 120 can be a rectangular parallelepiped, a cylinder, a cone, or other regular or irregular strip-shaped three-dimensional structures. For ease of description, the structure of the extension portion 120 may be defined as follows. For example, please refer to the attached Figure 4 , Attachment Figure 5 and attached Fig.12 The extension portion 120 may include an inner surface 125 facing the concha cavity 221, an outer surface 124 facing the outside of the human body, an outer side surface 126 facing the tragus and an inner side surface 127 facing the helix; the direction from the outer surface 124 to the inner surface 125 may be the thickness direction of the extension portion 120, and the direction from the outer side surface 126 to the inner side surface 127 is the short axis direction of the extension portion 120, that is, the width direction of the extension portion; the direction from the end of the extension portion 120 connected to the main body portion 110 to the end of the extension portion connected to the sound-emitting portion 130 is the long axis direction of the extension portion 120, that is, the length direction of the extension portion 120.

[0071] The inner surface 125 of the extension 120 gradually tilts toward the ear hook plane from the inner side 127 to the outer side 126; the ear hook plane is a plane tangent to the back of the earphone or a sagittal plane of the human body. In this way, in the direction perpendicular to the ear hook plane, there is a gap between the inner surface 125 of the extension 120 and the tragus, so as to reduce the squeezing and contact of the wearer's tragus and helix crus, thereby improving the wearing comfort of the earphone.

[0072] In some embodiments, the sound-emitting portion 130 is convexly disposed on the inner surface 125 of the extension portion 120, and the sound-emitting portion 130 and the extension portion 120 are stacked in the direction of the human coronal axis. In this way, in the wearing state, at least a portion of the inner surface 125 of the extension portion 120 is higher than the suprastragalus notch 211 in the Y-axis direction, and at least a portion of the sound-emitting portion 130 can be lower than the tragus in the Y-axis direction; therefore, on the one hand, the sound-emitting portion 130 can not squeeze the tragus and the suprastragalus notch 211, thereby improving the wearing comfort of the earphone. On the other hand, the sound-emitting portion 130 can extend into the concha cavity, and the sound-emitting portion 130 will be closer to the ear canal opening than the extension portion 120, making it easier for the sound of the earphone to enter the ear canal opening, thereby improving the sound quality of the earphone. In addition, since the sound-emitting portion 130 includes a speaker, and the size of the speaker has a great relationship with the sound quality of the earphone, compared with the design in which the sound-emitting portion 130 is usually arranged inside the extension portion 120 or the two are basically at the same height, in this embodiment, due to the stacking design of the sound-emitting portion 130 and the extension portion 120 in the Y-axis direction, the short axis of the extension portion 120 can be set narrower, while the sound-emitting portion can still have a large enough volume to accommodate a larger speaker. In this way, the narrower extension portion can reduce the squeezing of the auricle, antihelix and other areas, and it is also more beautiful; at the same time, the larger speaker can make the earphone still have better sound quality.

[0073] In some embodiments, at least part of the sound-emitting portion 130 is located inside the tragus of the ear, that is, at least part of the sound-emitting portion is located on the side of the tragus facing the ear canal opening. In some embodiments, the sound-emitting portion 130 is completely located inside the tragus of the ear. In this way, the sound-emitting portion 130 is located in the concha cavity 221, but does not extend into the ear canal. Under the premise of ensuring that the sound-emitting portion 130 is as close to the ear canal opening 280 as possible, the pressure on the ear canal can be reduced, the damage to the ear canal can be reduced, and it is suitable for long-term wear.

[0074] Furthermore, the transition surface between the sound-emitting portion 130 and the outer side of the extension portion 120 is a concave surface 140. Thus, when the earpiece is worn, the concave surface 140 can just provide an escape space for the tragus, thereby preventing the extension portion from squeezing the tragus.

[0075] In some embodiments, the end surface 134 of the sound-emitting portion facing away from the extension portion is inclined relative to the plane where the inner surface of the extension portion 120 is located. In this way, when the earphone is worn, the sound-emitting portion 130 can be located in the concha cavity, but the sound-emitting portion 130 can be prevented from squeezing the antihelix and the tragus, thereby improving the wearing comfort of the earphone.

[0076] It should be understood that the end surface 134 of the sound-emitting portion facing away from the extension portion can be tilted along a single dimension or along multiple dimensions relative to the inner surface of the extension portion 120. Exemplarily, the end surface of the sound-emitting portion 130 gradually tilts from the inner side surface 127 of the extension portion 120 to the outer side surface 126 of the extension portion 120 in the direction of the ear hook plane. In other words, the end surface of the sound-emitting portion 130 gradually tilts from the inner side surface 127 of the extension portion 120 to the outer side surface 126 of the extension portion 120 in the negative direction of the Y axis. With such an inclined setting, in the wearing state, the sound-emitting portion 130 can not only better face the ear canal opening, thereby improving the sound quality of the earphone; in addition, the end surface of the sound-emitting portion 130 can also avoid the crus of the helix, thereby avoiding squeezing of the crus of the helix, the antihelix and the tragus, thereby improving the wearing comfort.

[0077] Furthermore, in some embodiments, the end face of the sound-emitting portion 130 facing away from the extension portion 120 can also be gradually inclined toward the direction of the ear hook plane along the long axis of the extension portion 120. In other words, in addition to gradually inclining from the inner side surface 127 of the extension portion 120 to the outer side surface 126 of the extension portion 120 toward the negative direction of the Y-axis, the end face of the sound-emitting portion 130 can also be gradually inclined toward the negative direction of the Y-axis along the long axis direction of the extension portion 120. With such an inclined setting, when worn, the end face of the sound-emitting portion 130 can be closer to the ear canal, so that the sound-emitting portion 130 can be better opposite to the ear canal opening, thereby improving the sound quality of the earphone.

[0078] In some embodiments, when worn, the extension portion 120 and the helix of the ear have an ear root contact area, and the highest point of the projection of the ear root contact area on the ear hook plane along the vertical axis of the human body is defined as the ear hook vertex 212 of the earphone.

[0079] In some embodiments, the shortest vertical distance L11 between the projection of the outer circumferential surface of the sound-emitting portion 130 on the earhook plane and the earhook apex 212 of the earphone is 18 mm to 22 mm, and the maximum vertical distance L12 between the projection of the outer circumferential surface of the sound-emitting portion 130 on the earhook plane and the earhook apex 212 of the earphone is 37 mm to 44 mm.

[0080] In the present application, the above distance can be measured by the following method: the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane is made into a first tangent line 131 and a second tangent line 132, wherein the first tangent line 131 and the second tangent line 132 are parallel to the horizontal plane, the first tangent line 131 passes through the highest point of the projection of the outer peripheral surface on the ear hook plane along the vertical axis of the user, and the second tangent line 132 passes through the lowest point of the projection of the outer peripheral surface on the ear hook plane along the vertical axis of the user. Fig.15Taking the orientation shown as an example, the first tangent 131 and the second tangent 132 are both located below the ear hook vertex 212, and the first tangent 131 is located above the second tangent 132. If L11 is too small, the sound-emitting part 130 will be too close to the ear regions such as the suprasternal notch, the crus of the helix, and the tragus, so that one end of the sound-emitting part 130 may squeeze the above-mentioned ear regions; if L12 is too large, the other end of the sound-emitting part 130 will be too close to the ear regions such as the antihelix and the cavum concha, so that the sound-emitting part 130 will squeeze the antihelix and the cavum concha; by setting L11 and L12, in the wearing state, the sound-emitting part 130 can be well located in the cavum concha, and at the same time, it does not contact the ear regions such as the crus of the helix, the antihelix, and the cavum concha, so that the wearing comfort of the earphone can be improved.

[0081] In some embodiments, the width L13 of the projection of the extension portion 120 corresponding to the ear root contact area on the horizontal plane of the human body is less than or equal to 3 mm, so as to avoid the extension portion 120 squeezing the ear root and improve the wearing comfort of the earphone.

[0082] Please refer to the attached Fig.12 The extension portion 120 includes a first arc segment 121, a second arc segment 122, and a strip segment 123 for connecting the first arc segment 121 and the second arc segment 122. The end of the first arc segment 121 away from the strip segment 123 is connected to the main body 110, and the end of the second arc segment 122 away from the strip segment 123 is bent toward the concha cavity 221 of the ear 200 and connected to the sound-generating portion 130. The first arc segment 121 surrounds the helix of the ear so that the strip segment 123 connected thereto can be hung on the front side of the ear. It should be noted that the portion between the main body 110 and the strip segment 123 is defined as the first arc segment 121, or the portion between the main body 110 and the strip segment 123 can be further divided, for example, the portion between the main body 110 and the strip segment 123 can include a connecting segment 129 and the first arc segment 121.

[0083] In some embodiments, in the wearing state, the connecting section 129 may represent the section where the earphone contacts the ear root; the first arc section 121 may represent the arc section where the earphone crosses the helix but does not exceed the triangular fossa of the ear; and the long strip section 123 and the second arc section 122 may be bounded by the vertex of the extension portion 120 relative to the ear hook plane, the arc section at the end of the extension portion 120 is the second arc section, and the extension portion between the first arc section 121 and the second arc section 122 is the long strip section 123. Among them, the vertex 128 is the highest point where the extension portion 120 is raised relative to the ear hook plane. It should be understood that the shapes of the first arc section 121 and the connecting section 129 need to match the top of the helix and the shape of the second arc section 122 needs to match the concha cavity, that is, the connecting section 129, the first arc section 121 and the second arc section 122 are not regular shapes, therefore, the inner surface 125 of the extension portion 120 is inclined relative to the ear hook plane, which can be understood as the inner surface of the long strip section 123 is inclined relative to the ear hook plane.

[0084] The second arc segment 122 includes at least one of the following features:

[0085] The second arc segment 122 gradually bends from the inner side surface 127 of the extension portion 120 to the outer side surface 126 of the extension portion 120, so that the second arc segment 122 bends toward the concha cavity, presenting a visual effect of gradually narrowing in the short axis direction of the extension portion, so that when worn, the second arc segment 122 can avoid the antihelix and the concha cavity, prevent the ear from being squeezed, and improve wearing comfort. In addition, the connecting surface of the second arc segment 122 and the long strip segment 123 and the end surface of the second arc segment 122 facing away from the long strip segment 123 can be arranged vertically on the plane of the ear hook, which can effectively improve the space utilization rate, facilitate the reduction of the volume of the extension portion 120, and make the earphone 100 develop in the direction of miniaturization. On the other hand, the sound-emitting portion 130 can be closer to the ear canal opening 280, thereby improving the sound quality of the earphone.

[0086] The outer surface of the second arc segment 122 is bent from the connecting surface with the long strip segment 123 to the end of the second arc segment 122 toward the inner surface 125 of the gradually extending portion 120; that is, in the Y-axis direction, from the long strip segment 123 to the second arc segment 122, the outer surface of the extending portion 120 is bent toward the negative direction of the Y-axis, presenting a visual effect that the end of the second arc segment 122 is thinner, so that when worn, the outer surface of the second arc segment 122 can avoid the antitragus to prevent it from being squeezed.

[0087] The transition surface between the outer side surface of the second arc segment 122 and the sound-emitting portion 130 is a concave surface 140. Thus, when the earpiece is worn, the concave surface can just provide an escape space for the tragus, thereby preventing the extension portion from squeezing the tragus.

[0088] For further clarity of description, the inclination relationship between the extension portion 120 and the ear hook plane, and the inclination relationship between the end surface of the sound-emitting portion 130 facing away from the extension portion 120 and the inner surface of the extension portion 120 may be defined by taking a long strip segment 123 with a regular shape as an example.

[0089] For example, the inclined angle α2 between the inner surface of the long segment 123 and the ear hook plane; and / or the inclined angle α1 between the end surface 134 of the sound-emitting portion 1 away from the extension portion and the inner surface of the long segment 123. It should be understood that the selection and determination of the inclined angle α1 and the inclined angle α2 in this embodiment can be designed according to the orientation of the sound-emitting portion 130 relative to the ear canal opening in an ideal state; for example, please refer to the attached Figure 8 , attached Figure 8 The part near the ear canal opening is the simulated body of the sound-emitting part 130. Based on the origin of the three-dimensional coordinate axis as a reference, we can define the following angle range to indicate the ideal angle of the sound-emitting part pointing to the center of the ear canal opening:

[0090] In a coordinate system with the positive direction of the X-axis at 0° and the positive direction of the Y-axis at 90°, the angle at which the speaker points to the center of the ear canal opening is between +10° and +80°. In a coordinate system with the positive direction of the X-axis at 0° and the positive direction of the Z-axis at 90°, the angle at which the speaker points to the center of the ear canal opening is between -70° and +70°. In a coordinate system with the positive direction of the Y-axis at 0° and the positive direction of the Z-axis at 90°, the angle at which the speaker points to the center of the ear canal opening is between -70° and +70°. The overlapping parts of the above three angle ranges form a spatial angle range, which is the optimal angle for indicating that the sound-emitting part 130 points to the center of the ear canal opening.

[0091] The inclined angle α2 between the inner surface of the long strip section 123 and the ear hook plane is 8° to 9°. For example, the values ​​of the inclined angle α2 are 8°, 8.2°, 8.4°, 8.5°, 8.8° and 9°. By adjusting the size of the inclined angle α2, the end of the extension part 120 away from the main body 110 can be as close to the concha cavity 221 as possible, while avoiding the extension part 120 from squeezing the tragus 230 in the direction perpendicular to the ear hook plane 300, so as to facilitate the sound-generating part 130 of the earphone to be closer to the ear canal opening (see the attached Figure 6 ), improving the sound quality of the headphones.

[0092] The tilt angle α1 between the end surface of the sound-emitting portion 130 away from the extension portion 120 and the inner surface of the long strip segment 123 is 22° to 28°. Among them, the values ​​of the tilt angle α1 are 22°, 22.5°, 23°, 23.5°, 24°, 24.5°, 25°, 25.5°, 26°, 26.5°, 27°27.5° and 28°. Preferably, the value of the tilt angle α1 is 27.5°. By limiting the tilt angle α1, this embodiment can make the sound-emitting portion 130 have an ideal angle pointing to the center point of the ear canal opening when the sound-emitting portion 130 is arranged relative to the ear canal opening, so that the sound quality of the earphone is clearer and the audio experience is better. In addition, the extension portion 120 can avoid the helix crus and the tragus and the sound-emitting portion 130 can avoid the concha cavity, avoiding squeezing the helix crus, the tragus and the concha cavity, thereby improving the wearing comfort of the earphone.

[0093] The earphone provided in this embodiment is reasonably designed through the tilt angle α1 and the tilt angle α2, so that the two complement each other, so as to ensure that the sound-emitting part 130 is close to the ear canal opening and the sound quality of the earphone is guaranteed. At the same time, it can also be perpendicular to the plane of the ear hook, so that there is a gap between the extension part 120 and the auricle and the ear wheel, so as to avoid the extension part 120 squeezing the auricle and the ear wheel; at the same time, it can also avoid the sound-emitting part 130 squeezing the auricle and the tragus.

[0094] In some embodiments, please refer to the attached Fig.12 and attached Fig.19 , the distance L3 between the projection of the outer edge point 133 of the sound-emitting part on the ear hook plane and the projection of the outer side surface of the long strip segment 123 on the ear hook plane ranges from 3mm to 5mm. For example, the values ​​of L3 are 3mm, 4mm and 5mm. Among them, the outer edge point 133 of the sound-emitting part is the point farthest from the outer side surface of the long strip segment 123 in the outer peripheral surface of the sound-emitting part 130 and the part away from the antihelix 250. By limiting L3 and cooperating with other features of the extension part 120, this embodiment can prevent the sound-emitting part 130 from squeezing the concha cavity 221 and make the sound-emitting part 130 more miniaturized.

[0095] Please refer to the attached Fig. 20, the distance L1 between the end face of the sound-emitting part 130 away from the extension part 120 and the vertex of the extension part 120 in the direction of the human coronal axis is in the range of 12 mm to 16 mm. For example, the distance L1 between the end face of the sound-emitting part 130 away from the extension part 120 and the vertex of the extension part 120 is 12 mm, 13 mm, 14 mm, 15 mm or 16 mm. The vertex of the extension part 120 is the highest point where the extension part 120 is raised relative to the ear hook plane. By limiting the distance L1 between the end face of the sound-emitting part 130 away from the extension part 120 and the vertex of the extension part 120, the sound-emitting part 130 can be prevented from squeezing the cavum concha 221, and the sound-emitting part 130 can be brought closer to the ear canal opening, thereby improving the sound quality of the earphone.

[0096] Please refer to the attached Fig.13 and attached Fig.24 , the distance L8 between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane is in the range of 13mm to 16mm; if the distance L8 between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane is greater than 16mm, the tragus will be squeezed; if the distance L8 between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane is less than 13mm, the concha cavity will be squeezed. Therefore, this embodiment limits L8, and on the premise of ensuring that the sound-emitting part 130 is located in the concha cavity, it is also necessary to avoid the extension part 120 squeezing the tragus and the concha cavity, thereby improving the wearing comfort of the earphone.

[0097] In some embodiments, please refer to the attached Fig.21 and attached Fig. 22 , the axial thickness L2 of the sound-emitting part 130 is less than 12 mm; and / or, the maximum outer diameter d1 of the sound-emitting part 130 has a value range of 10 mm to 15 mm, for example, the maximum outer diameter d1 of the sound-emitting part 130 has a value of 10 mm. With such a configuration, the size of the sound-emitting part 130 can be reduced, which can not only prevent the sound-emitting part 130 from squeezing the tragus and the antihelix, but also facilitate the development of the earphone in the direction of miniaturization. Among them, the thickness of the sound-emitting part 130 can be measured in the following manner: a vertical line is made from the geometric center of the end face 134 of the sound-emitting part away from the extension part, and the vertical line can be regarded as the central axis of the sound-emitting part, and the thickness of the sound-emitting part 130 on the central axis is the thickness L2 of the sound-emitting part; and the maximum outer diameter of the sound-emitting part 130 can be measured as follows: on the end face of the sound-emitting part away from the extension part, the distance between the two outer edge points with the largest distance is measured as the maximum outer diameter d1 of the sound-emitting part.

[0098] At the same time, the distance L9 between the end face of the sound-emitting part 130 away from the extension part 120 and the ear hook plane on the coronal axis ranges from -4mm to 2mm. For example, the value of L9 is -4mm, -3mm, -2mm, -1mm, 0, 0.5mm, 1mm, 1.5mm or 2mm. Among them, a negative number means that at least part of the end face of the sound-emitting part away from the extension part is lower than the ear hook plane. With this arrangement, the sound-emitting part 130 can avoid the concha cavity, thereby preventing the sound-emitting part 130 from squeezing the concha cavity.

[0099] Please refer to the attached Fig.25 , along the long axis of the extension portion 120, the length L10 of the long segment 123 ranges from 28 mm to 32 mm. For example, the length L10 of the long segment 123 ranges from 28 mm, 29 mm, 30 mm, 31 mm, and 32 mm. If the length L10 of the long segment 123 is less than 28 mm, it cannot be ensured that the sound-emitting portion 130 is in the concha cavity, which reduces the sound quality of the earphone 100 and squeezes the tragus. If the length L10 of the long segment 123 is greater than 32 mm, the long segment 123 will be too long, causing the sound-emitting portion 130 to squeeze the antihelix. Therefore, this embodiment limits the length of the long segment 123, which can ensure that the sound-emitting portion 130 is in the concha cavity, improving the sound quality of the earphone 100, and can also avoid squeezing the tragus and the antihelix.

[0100] The embodiment of the present application also provides an earphone, wherein the earphone includes a main body 110, an extension portion 120 connected to the main body 110, and a sound-emitting portion 130 connected to the extension portion 120; in a wearing state, an end of the main body 110 away from the extension portion 120 extends downward along the rear side of the ear, and the end of the extension portion 120 away from the main body 110 bypasses the top of the helix of the ear and extends toward the concha cavity of the ear, and at least a part of the sound-emitting portion 130 is within the tragus; wherein the extension portion 120 includes a first arc segment 121, a long strip segment 123, and a second arc segment 122 connected in sequence, an end of the first arc segment 121 away from the long strip segment 123 is connected to the main body 110, and an end of the second arc segment 122 away from the long strip segment 123 is bent toward the concha cavity of the ear, and the sound-emitting portion 130 is convexly arranged on the inner surface of the second arc segment 122, and in the direction of the coronal axis of the human body, the sound-emitting portion 130 and the second arc segment 122 are stacked.

[0101] In this embodiment, the sound-emitting portion 130 is convexly arranged on the inner surface of the second arc segment 122, and the sound-emitting portion 130 and the extension portion 120 are stacked in the direction of the human coronal axis. In this way, the sound-emitting portion 130 and the extension portion 120 are stacked in the Y-axis direction. In the wearing state, at least a portion of the inner surface 125 of the extension portion 120 is higher than the suprasternal notch 211 in the Y-axis direction, and at least a portion of the sound-emitting portion 130 can be lower than the tragus in the Y-axis direction; therefore, on the one hand, the sound-emitting portion 130 can not squeeze the tragus and the suprasternal notch 211, thereby improving the wearing comfort of the earphone. In addition, due to the stacking design of the sound-emitting portion 130 and the extension portion 120 in the Y-axis direction, the short axis of the extension portion 120 can be set narrower, while the sound-emitting portion can still have a large enough volume to accommodate a larger speaker. In this way, the narrower extension portion can reduce the squeezing of the tragus, antihelix and other areas, and is more beautiful, thereby improving the wearing comfort of the earphone.

[0102] In some embodiments, the earphone further includes a battery and a mainboard, and the battery is used to provide power output to the mainboard and the sound-emitting part 130. The battery can be arranged on the main body 110 or on the extension part 120. In one example, the battery is arranged at the end of the main body 110 away from the extension part 120, and the mainboard is arranged on the extension part 120, so that the battery is arranged relative to the mainboard and the sound-emitting part 130, which can better balance the weight of the earphone 100 and provide a more comfortable wearing experience. In another example, the battery and the mainboard are arranged on the extension part 120 at intervals. In order to ensure the normal operation of the mainboard, a wire needs to be arranged between the battery and the mainboard, and the wire can be routed in the extension part 120; by arranging the battery and the mainboard at intervals in the extension part 120, it is not necessary to route the wire in the main body 110, and the length of the wire used to connect the battery and the mainboard can be shortened, making the processing technology of the earphone 100 simpler and reducing the production cost of the earphone 100.

[0103] Please continue to refer to the attached Fig.14 , the cross-sectional area of ​​the main body 110 gradually increases along the direction away from the extension portion 120, that is, along the direction away from the extension portion 120, the cross-sectional area of ​​the main body 110 gradually increases. Fig.14 From top to bottom, the cross-sectional area of ​​the main body 110 gradually increases. Compared with the technical solution in which the cross-sectional area of ​​the main body 110 is equal everywhere, the volume and weight of the main body 110 can be reduced, and the wearing comfort of the earphone is improved. Among them, the cross-sectional area of ​​the end of the main body 110 away from the extension 120 is the largest. Under the premise of reducing the volume of the main body 110, the weight of the earphone can be better balanced and the wearing comfort of the earphone can be improved.
