[0061] As described in the background art, the sound quality of open-type earphones in the related art is relatively poor and has low acoustic performance. The inventors have found that the reason for this problem is that open-type earphones are usually covered on the outside of the ear, so that the distance between the sound-emitting part of the open-type earphones and the ear canal opening is relatively large, which affects the sound quality of the earphones.

[0062] In view of the above technical problems, the embodiment of the present application provides an earphone, comprising a main body, an extension and a sounding part; one end of the main body is connected to the extension, and 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; in the wearing state, the extension and the helix of the ear have an ear root contact area; the sounding part is connected to the end of the extension away from the main body, the shortest vertical distance L11 between the projection of the outer peripheral surface of the sounding part on the ear hook plane and the ear hook vertex of the earphone is 18mm-22mm, and the maximum vertical distance L12 between the projection of the outer peripheral surface of the sounding part on the ear hook plane and the ear hook vertex of the earphone is 37mm-44mm; wherein, the highest point of the projection of the ear hook contact area on the ear hook plane along the vertical axis of the human body is defined as the ear hook vertex of the earphone. With such a setting, on the one hand, the sounding part can be arranged relative to the concha cavity, so that the sounding part is closer to the ear canal opening, thereby improving the sound quality of the earphone. On the other hand, under the premise of ensuring that the sound-producing part is as close to the opening of the ear canal as possible, the position of the sound-producing part in the concha cavity is also limited to avoid the sound-producing part squeezing the antitragus and the helix crus, thereby improving the wearing comfort of the earphones.

[0063] 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.

[0064] 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.

[0065] Please refer to the attached Figure 1 The ear 200 of the user may include structures such as a helix 210, a suprastragal notch 211, 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 cavum concha 221.

[0066] The front and back sides of the ear are defined as follows: 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 upwards, and the "lower edge of the ear" refers to the outer edge of the ear's helix facing downwards, and they are both for the user's ear.

[0067] 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.

[0068] 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.

[0069] 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, and 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 and the human body sagittal plane are parallel, 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.

[0070] Please continue to refer to the attached Figure 5-6 and attached Figures 9 to 22 The earphone 100 provided in this embodiment includes a main body 110, an extension part 120 and a sound-emitting part 130. One end of the main body 110 is connected to the extension part 120, that is, 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 part 120. Among them, the main body 110 is used to be hung on the back side of the ear, and can be balanced with the extension part 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 110 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 an antenna, Bluetooth and other electronic components for communicating with other devices.

[0071] For the convenience of description, in some embodiments, in the wearing state, the extension portion 120 and the main body 110 can be divided by the ear root contact area on the earphone that contacts the ear root. 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. Of course, in some embodiments, the main body and the extension can also be distinguished by the part with the smallest cross-sectional area of ​​the earphone as the boundary. In other words, along the direction of the earphone, the main body and the extension can be divided by the thinnest part of the earphone as the boundary.

[0072] Please refer to the attached Figure 1 , Attachment Figure 5 , Attachment Figure 6 And attached Fig.10 In some embodiments, when worn, the end of the main body 110 away from the extension 120 extends downward along the back side of the ear, and the end of the extension 120 away from the main body 110 bypasses the top of the helix of the ear 200, passes through the suprasternal notch 211, and extends toward the concha cavity of the ear. Fig.10 The extension part 120 and the helix have an ear root contact area 212, and the ear root contact area 212 supports the earphone so as to stably support the earphone on the ear. It should be noted that the ear root contact area 212 can be understood as the contact area between the extension part 120 and the helix, which can be attached Fig.10 The extending portion 120 is included in the dotted line frame.

[0073] Please refer to the attached Figure 6 , Attachment Fig.13 as well as Fig.15 , the sound-emitting portion 130 is connected to the end of the extension portion 120 away from the main body 110; in some embodiments, the sound-emitting portion 130 can be a cube, a rectangular parallelepiped, a cylinder, an ellipsoid, a cone, or other regular and irregular three-dimensional structures. Correspondingly, the sound-emitting portion 130 can have a projection of a corresponding shape on the sagittal plane or the ear hook plane. For example, the projection shape of the sound-emitting portion can be a square, a rectangle, a circle, an ellipse, a rounded rectangle, a runway, or other regular or irregular shapes. It is easy to understand that this is related to the outer peripheral surface of the sound-emitting portion. In some embodiments, such as Fig.15 As shown, the projection of the outer peripheral surface of the sound-emitting portion 130 on the ear hook plane is approximately circular.

[0074] In some embodiments, please refer to the attached Fig.15 As shown, the highest point of the projection of the ear base contact area 212 on the ear hook plane along the user's vertical axis direction can be called the ear hook apex 213, the shortest vertical distance between the ear hook apex 213 and the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane is L11, and the maximum vertical distance between the ear hook apex and the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane is L12. In the present application, the above distances can be measured by the following method: a first tangent 131 and a second tangent 132 are made for the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane, wherein the first tangent 131 and the second tangent 132 are parallel to the horizontal plane, the first tangent 131 passes through the highest point of the projection of the outer peripheral surface on the ear hook plane along the user's vertical axis direction, and the second tangent 132 passes through the lowest point of the projection of the outer peripheral surface on the ear hook plane along the user's vertical axis direction. With the attached figure, Fig.15Taking the shown orientation as an example, the first tangent line 131 and the second tangent line 132 are both located below the ear hook apex 213 , and the first tangent line 131 is located above the second tangent line 132 .

[0075] In some embodiments, the shortest vertical distance L11 between the ear hook vertex 213 and the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane is 18-22 mm, and the maximum vertical distance L12 between the ear hook vertex 213 and the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane is 37-44 mm. By setting the shortest vertical distance L11 between the ear hook vertex 213 and the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane and the maximum vertical distance L12 between the ear hook vertex 213 and the projection of the outer peripheral surface of the sound-emitting part 130 on the ear hook plane, on the one hand, the sound-emitting part 130 can be arranged opposite to the cavum concha, so that the sound-emitting part 130 is closer to the ear canal opening, thereby improving the sound quality of the earphone. On the other hand, if L11 is too small, the sound-emitting part 130 will be too close to the ear areas such as the supratragical 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 areas; if L12 is too large, the other end of the sound-emitting part 130 will be too close to the ear areas such as the antihelix and the cavity concha, so that the sound-emitting part 130 will squeeze the antihelix and the cavity concha; therefore, by setting L11 and L12, when the earphone is worn, the sound-emitting part 130 can be well located in the cavity concha, and at the same time will not contact the ear areas such as the crus of the helix, the antihelix and the cavity concha, thereby improving the wearing comfort of the earphone.

[0076] 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. The structure of the extension portion 120 may be defined as follows. For example, please refer to the attached Fig.10 , Attachment Fig.11 And attached Fig.13 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 can be considered as the thickness direction of the extension portion 120, the direction from the outer side surface 126 to the inner side surface 127 can be considered as the short axis direction of the extension portion 120, that is, the width direction of the extension portion, and the direction from the end of the extension portion 120 connected to the main body portion 110 to the end of the extension portion 120 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.

[0077] Please refer to the attached Figures 4 to 6 as well as Fig.24In some embodiments, the sound-emitting portion 130 is connected to the end of the extension portion 120 away from the main body portion 110. The sound-emitting portion 130 can be disposed on the inner surface 125 of the extension portion. When worn, the sound-emitting portion 130 is located on the side of the extension portion 120 facing the concha cavity. In this way, the sound-emitting portion 130 will be closer to the ear canal opening, thereby improving the sound quality of the earphone.

[0078] Please refer to the attached Figures 4 to 6 , Attachment Figures 13 to 16 And attached Fig.24 In some embodiments, the sound-emitting portion 130 is convexly disposed on the inner surface 125 of the extension portion, 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, the sound-emitting portion 130 and the extension portion 120 are stacked in the Y-axis direction, at least a portion of the inner surface 125 of the extension portion 120 is higher than the tragus 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, 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, so that the sound of the earphone can enter the ear canal opening more easily, thereby improving the sound quality of the earphone.

[0079] 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 (the sound-emitting portion is not protruding compared to the extension portion), in this embodiment, due to the stacking design of the sound-emitting portion 130 and the extension portion 120 in the direction of the human body's coronal axis, 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 is more beautiful and conducive to miniaturization; at the same time, the earphone can still have good sound quality.

[0080] It should be noted that the sound quality effect in this embodiment includes but is not limited to the volume of the earphone and the clarity of the sound quality of the earphone.

[0081] Please refer to the attached Fig.24 In some embodiments, in order to make the sound-emitting part 130 better face the ear canal opening, the sound-emitting part 130 can be tilted on the inner surface 125 of the extension part. Because the concha cavity usually has a curved transition toward the ear canal opening, when the earphone is worn, tilting the sound-emitting part 130 on the inner surface of the extension part can make it easier for the sound-emitting part 130 to get close to the sound canal opening when in the concha cavity, thereby improving the sound quality of the earphone.

[0082] In some embodiments, as shown in the attached Fig.13 and 14As shown, the end surface 134 of the sound-emitting portion away from the extension portion (i.e., the end surface of the sound-emitting portion 130 away from the outer surface of the extension portion 120) is inclined relative to the plane where the inner surface 125 of the extension portion 120 is located. Exemplarily, the end surface 134 of the sound-emitting portion away from the extension portion is gradually inclined from the inner side surface 127 of the extension portion 120 to the outer side surface 126 of the extension portion 120 toward the direction of the ear hook plane, and / or, the end surface 134 of the sound-emitting portion away from the extension portion is gradually inclined toward the direction of the ear hook plane along the long axis of the extension portion 120.

[0083] With such arrangement, the end face of the sound-emitting part 130 is inclined relative to the sagittal plane of the human body in three-dimensional space. When worn, the end face of the sound-emitting part 130 can be closer to the concha cavity, and the sound-emitting part 130 can not only better correspond to the opening of the ear canal, thereby improving the sound quality of the earphone; in addition, the end face of the sound-emitting part 130 can also avoid the crus of the helix, thereby avoiding squeezing the crus of the helix, thereby improving wearing comfort.

[0084] Please continue to refer to the attached Fig.14 In some embodiments, the end surface of the sound-emitting portion 130 that faces away from the extension portion 120 is inclined relative to the plane where the inner surface 125 of the extension portion 120 is located, and the inclined angle α1 between the end surface of the sound-emitting portion 130 and the plane where the inner surface 125 of the extension portion 120 is located is 22° to 28°. For example, the inclined angle α1 is 22°, 22.5°, 23°, 23.5°, 24°, 24.5°, 25°, 25.5°, 26°, 26.5°, 27°27.5° and 28°. Preferably, the inclined angle α1 is 27.5°. In this embodiment, there is a preset inclined angle α1 between the end surface 134 of the sound-emitting portion that faces away from the extension portion and the inner surface 125 of the extension portion, so that when the sound-emitting portion 130 is arranged relative to the ear canal opening, the sound-emitting portion 130 can have an ideal angle pointing to the center point of the ear canal opening, thereby making the sound quality of the earphone clearer and the audio experience more excellent;

[0085] It should be understood that the selection of the tilt angle α1 in this embodiment can be designed according to the orientation of the sound-emitting part 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:

[0086] In the coordinate system with the positive direction of the X axis as 0° and the positive direction of the Y axis as 90°, the angle of the speaker pointing to the center of the ear canal opening is between +10° and +80°. In the coordinate system with the positive direction of the X axis as 0° and the positive direction of the Z axis as 90°, the angle of the speaker pointing to the center of the ear canal opening is between -70° and +70°. In the coordinate system with the positive direction of the Y axis as 0° and the positive direction of the Z axis as 90°, the angle of the speaker pointing to the center of the ear canal opening is between -70° and +70°.

[0087] The overlapping parts of the above three angle ranges form a spatial angle range, which is the best angle for indicating that the sound-emitting part 130 is pointing to the center point of the ear canal opening.

[0088] The embodiment of the present application also limits the size of each part of the earphone to better ensure that the sound-emitting part 130 can be closer to the ear canal opening 280.

[0089] In some embodiments, the earphone 100 includes an open earphone, and when worn, the sound-emitting portion 130 is located in the concha cavity 221 of the ear 200. This arrangement can make the sound-emitting portion 130 closer to the ear canal opening, thereby improving the sound quality and volume performance of the earphone.

[0090] In some embodiments, when the earphone 100 is worn, at least part of the sound-emitting part is located inside the tragus of the ear, that is, at least part of the sound-emitting part is located on the side of the tragus facing the ear canal opening. In some embodiments, the entire sound-emitting part is located inside the tragus. It should be noted that, relative to in-ear earphones, the sound-emitting part of open-type earphones will not extend into the ear canal. The sound-emitting part 130 of the earphone of the present application is located in the concha cavity 221. On the premise of ensuring that the sound-emitting part 130 is as close to the ear canal opening 280 as possible, it will not extend into the ear canal, which can reduce the pressure on the ear canal, reduce damage to the ear canal, and is suitable for long-term wear.

[0091] In some embodiments, please refer to the attached Fig.16, along the direction of the human coronal axis, 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 to 16 mm. For example, the value of 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. Among them, the vertex of the extension part 120 is the highest point of the extension part 120 relative to the ear hook plane. If L1 is too large, the end face of the sound-emitting part 130 will be too close to the concha cavity. 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 will be prevented from squeezing the concha cavity 221. In some embodiments, by limiting the size of L1 and the aforementioned tilt angle α1, the sound-emitting part 130 can be made closer to the ear canal opening, thereby improving the sound quality of the earphone and preventing the sound-emitting part 130 from squeezing the concha cavity 221.

[0092] In some embodiments, please refer to the attached Fig.17 , the distance L8 between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane is 1mm 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 distance between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane will be increased. Under the condition that the aforementioned L1 remains unchanged, the distance between the sound-emitting part 130 and the ear canal opening 280 is further increased; 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 1mm, it will cause extrusion in the concha cavity. Therefore, by limiting the distance L8 between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane, while ensuring that the sound-emitting part 130 is sufficiently close to the ear canal opening, it is also possible to avoid the extension part 120 from squeezing the tragus and the concha cavity, thereby improving the wearing comfort of the earphone.

[0093] It should be understood that in this example, the distance L8 between the vertex of the extension portion 120 relative to the ear hook plane and the ear hook plane also complements the distance L1 between the end face of the sound-emitting portion 130 facing away from the extension portion 120 and the vertex of the extension portion 120, which can better ensure that the sound-emitting portion 130 is closer to the ear canal opening, and thus make the sound outlet of the sound-emitting portion 130 close to the ear canal opening.

[0094] Please refer to the attached Fig.18In a possible implementation, the distance L9 between the end face of the sound-emitting part 130 away from the extension part 120 and the ear hook plane in the direction of the human coronal axis is -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 indicates 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. Such a setting can better ensure that the sound-emitting part 130 is closer to the ear canal opening and improve the sound quality of the earphone 100. In addition, by limiting the distance L9 between the end face of the sound-emitting part 130 away from the extension part 120 and the ear hook plane in the direction of the human coronal axis, the sound-emitting part 130 can also avoid the concha cavity, thereby preventing the sound-emitting part 130 from squeezing the concha cavity.

[0095] Further, in some embodiments, please refer to the attached Fig.19 , the distance L14 between the projection of the end surface 134 of the sound-emitting part away from the extension part on the human coronal plane and the inner surface of the extension part 120 in the direction of the human coronal axis is greater than 1.5 mm. This minimum distance L14 complements the aforementioned tilt angle α1, which can better ensure that the sound-emitting part 130 is closer to the ear canal opening, thereby improving the sound quality of the earphone 100.

[0096] To further refine the extension portion 120, please continue to refer to the attached Fig.10 and attached Fig.14 The extension portion 120 includes a first arc segment 121, a long strip segment 123, and a second arc segment 122 connected in sequence. The end of the second arc segment 122 away from the long strip segment 123 is bent toward the concha cavity of the ear and connected to the sound-generating portion 130. The first arc segment 121 surrounds the helix of the ear so that the long 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 long strip segment 123 is defined as the first arc segment 121, or the portion between the main body 110 and the long strip segment 123 can be further divided. For example, the portion between the main body 110 and the long strip segment 123 can include a connecting segment 129 and the first arc segment 121.

[0097] 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 segment 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 segment 123. The vertex 128 is the highest point where the extension portion 120 is raised relative to the ear hook plane.

[0098] It should be understood that in this embodiment, the shapes of the connecting section 129 and the first arc section 121 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, in this embodiment, the inclined angle α1 can refer to the long strip section 123, that is, the plane where the inner surface of the long strip section 123 is located represents the plane where the inner surface of the extension portion 120 is located. Exemplarily, there is an inclined angle α1 between the end surface 134 of the sound-emitting portion away from the extension portion and the inner surface of the long strip section 123, and the inclined angle α1 is 22° to 28°.

[0099] In this embodiment, the end of the second arc segment 122 that is away from the long strip segment 123 is bent toward the concha cavity 221 of the ear 200, which can improve the wearing comfort of the earphone. Specifically, the end of the second arc segment 122 that is away from the long strip segment 123 is bent toward the concha cavity 221 in three-dimensional space. On the one hand, the second arc segment 122 is not only gradually bent from the inner side surface 127 of the extension portion 120 to the outer side surface 126 of the extension portion 120, presenting a visual effect of gradually narrowing in the short axis direction of the extension portion 120, so that when the second arc segment 122 is worn, it can avoid the antihelix and the concha cavity to prevent squeezing the ear; on the other hand, the outer surface of the second arc segment 122 gradually bends from the connection surface with the long strip segment 123 to the end of the second arc segment 122. The inner surface of the extension portion 120 is curved; that is, in the Y-axis direction, from the long strip segment 123 to the second arc segment 122, the surface of the extension portion 120 is curved 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 the antitragus from being squeezed; on the other hand, the transition surface of the outer side of the second arc segment 122 facing the sound-emitting portion 130 is a concave surface, so that when worn, the concave surface can just provide an avoidance space for the tragus to prevent the extension portion from squeezing the tragus.

[0100] In addition, in this embodiment, the sound-emitting portion 130 and the extension portion 120 are stacked in the direction of the human coronal axis, and the projection of the sound-emitting portion 130 on the ear hook plane at least partially overlaps with the projection of the second arc segment 122 on the ear hook plane. On the one hand, the space utilization rate can be effectively improved, and the volume of the extension portion 120 can be reduced, so that the earphone 100 is developed in the direction of miniaturization. On the other hand, the sound-emitting portion 130 can be made closer to the ear canal opening 280, thereby improving the sound quality of the earphone.

[0101] In some embodiments, please refer to the attached Fig. 20, 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 is 3mm to 7mm. For example, the value of L3 is 3mm, 4mm, 5mm, 6mm or 7mm. 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; a larger L3 may cause the sound-emitting part to squeeze the concha cavity below the tragus.

[0102] This embodiment achieves high sound quality by limiting the degree to which the sound-emitting part 130 extends outward, and 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, cooperates with other features of the extension part 120, and can also prevent the sound-emitting part 130 from squeezing the concha cavity 221, and make the sound-emitting part 130 more miniaturized.

[0103] Please refer to the attached Fig.21 , along the long axis of the extension portion 120, the length L10 of the long segment 123 is 28mm to 32mm. For example, the length L10 of the long segment 123 is 28mm, 29mm, 30mm, 31mm and 32mm. Among them, the length of the long segment is the length in the extension direction of the long segment, that is, the length of the long segment along the long axis direction of the extension portion from the first arc segment 121 to the second arc segment 122. If the length L10 of the long segment 123 is less than 28mm, it cannot be guaranteed that the sound-emitting part 130 is in the concha cavity, which reduces the sound quality of the earphone 100 and squeezes the tragus, helix crus and supratragical notch. If the length L10 of the long segment 123 is greater than 32mm, the long segment 123 will be too long, which will cause the sound-emitting part 130 to squeeze the antihelix.

[0104] Therefore, this example limits the length range of the long segment 123. On the one hand, the sound-emitting part 130 can be placed exactly in the concha cavity 221 and close to the ear canal opening, thereby improving the sound quality of the earphone; on the other hand, while ensuring that the sound-emitting part 130 is located exactly in the concha cavity 221, it can also avoid the sound-emitting part 130 squeezing the tragus, the helix crus, the supratragalus notch and the antihelix, thereby improving the wearing comfort of the earphone.

[0105] It should be noted that the length range of the long segment 123 provided in this embodiment can also cooperate with the value range of the distance L8 between the vertex of the extension part 120 relative to the ear hook plane and the ear hook plane to ensure that the sound-emitting part 130 can better approach the ear canal opening.

[0106] In some embodiments, please refer to the attached Fig. 22, along the long axis of the extension portion 120, or in other words, the second arc segment 122 along the extension direction of the long strip segment 123, the length L15 of the second arc segment 122 is 13mm to 17mm. For example, the length L15 of the second arc segment 122 along the extension direction of the long strip segment 123 is 13mm, 14mm, 15mm, 16mm or 17mm. By limiting the length of the second arc segment 122, the length of the extension portion 120 in the extension direction of the long strip segment 123 can be more accurately controlled, so that the sound-emitting portion 130 is exactly located in the concha cavity, which is conducive to the sound-emitting portion 130 being better close to the ear canal opening, thereby improving the sound quality of the earphone.

[0107] To further improve the sound quality of the headphones, please refer to the attached Fig.23 And attached Fig.24 The earphone 100 further includes a first sound outlet hole 140, which is disposed on the sound-emitting portion 130. In some embodiments, the first sound outlet hole 140 is disposed on an end surface of the sound-emitting portion 130. Specifically, on the end surface of the sound-emitting portion 130 away from the extension portion 120, the first sound outlet hole 140 is located on a side of the sound-emitting portion 130 close to the ear canal opening, that is, a side close to the outer side surface of the extension portion 120; in some embodiments, the first sound outlet hole 140 can also be disposed on a transition surface where the sound-emitting portion 130 is connected to the second arc segment 122, that is, the first sound outlet hole 140 is disposed on a transition surface between the outer side surface of the second arc segment 122 and the sound-emitting portion 130. With such arrangement, when worn, the first sound hole 140 can be better directed to the ear canal opening, and the center distance between the first sound hole 140 and the ear canal opening will also be smaller. For example, the center distance between the first sound hole and the ear canal opening is no more than 6 mm. In this embodiment, the design of the first sound hole 140 can ensure that the sound emitted by the sound-emitting part 130 can be directly transmitted to the ear canal opening, thereby improving the performance of the sound quality and volume.

[0108] In some embodiments, as shown in the attached Figure 4 And attached Figure 5 As shown, the earphone 100 further includes a second sound outlet hole 150, which is disposed on the inner side of the extension portion 120. Specifically, the second sound outlet hole 150 can be disposed on the inner side of the second arc segment 122. In this way, when the earphone is worn, the second sound outlet hole 150 faces the concha cavity below the antihelix, and the sound emitted by the second sound outlet hole can still easily enter the concha cavity and then the ear canal, thereby improving the sound quality of the earphone. In addition, the position of the second sound outlet hole 150 can be well hidden, thereby improving the aesthetics of the earphone. In some embodiments, the second sound outlet hole 150 can also serve as a pressure relief hole.

[0109] It should be noted that the earphone 100 further includes a battery and a mainboard, wherein 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, the mainboard and the sound-emitting part 130 are arranged opposite to each other, 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. In this embodiment, 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 battery and the mainboard are both arranged in the extension part 120, which can shorten the length of the wire used to connect the battery and the mainboard, making the processing technology of the earphone 100 simpler and reducing the production cost of the earphone 100.

[0110] Please continue to refer to the attached Fig.12 , 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.12 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.
