The ear hook has an ear hook symmetry plane arranged along its length. When the ear-clip earphone is in its natural state, on the ear hook symmetry plane, the ear-clip earphone has a reference tangent line. The contour lines of the sound-emitting part and the abutment part are respectively tangent to the reference tangent line, and the contour lines of the sound-emitting part and the abutment part are located on the same side of the reference tangent line.

[0005] In some embodiments, when the ear clip-on headphones are in their natural state, a second reference point is located on the contour line of the contact portion on the symmetrical surface of the ear hook, which is closest to the sound-emitting part. The distance between the second reference point and the reference vertical line is 2-8 mm.

[0006] In some embodiments, the line connecting the second reference point and the first reference point is referred to as the first reference line; when the ear clip-on earphone is in its natural state, on the symmetrical plane of the ear hook, there is a third reference point on the inner contour line of the ear hook that is furthest from the second reference point, and the line connecting the second reference point and the third reference point is referred to as the second reference line, which is located on the side of the first reference line closer to the contact portion.

[0007] In some embodiments, when the ear clip-on headphones are in their natural state, the angle between the first reference line and the second reference line is 8°-25°.

[0008] In some embodiments, when the ear clip-on headphones are in their natural state, the angle between the first reference line and the reference tangent is 50°-85°.

[0009] In some embodiments, when the clip-on earphone is in its natural state, the length of the second reference connection is 13-20mm.

[0010] In some embodiments, when the ear clip-on headphones are in their natural state, on the symmetrical plane of the ear hook, a reference vertical line has a first side and a second side that are set opposite to each other, and the sound-emitting part is located on the first side of the reference vertical line; on the first side of the reference vertical line, the inner contour line of the ear clip-on headphones has a fourth reference point that is furthest from the reference vertical line, and the distance between the fourth reference point and the reference vertical line is recorded as the first distance, which is 4-9mm.

[0011] In some embodiments, when the ear clip-on headphones are in their natural state, on the second side of the reference vertical line, there is a fifth reference point on the inner contour line of the ear clip-on headphones that is furthest from the reference vertical line. The distance between the fifth reference point and the reference vertical line is denoted as the second distance, which is 7-13 mm.

[0012] In some embodiments, when the ear clip-on headphones are in their natural state, on the ear hook symmetry plane, the arc-to-chord ratio of the inner contour line of the ear clip-on headphones between the first reference point and the fourth reference point is 1.08-1.20, and the arc-to-chord ratio of the inner contour line of the ear clip-on headphones between the first reference point and the fifth reference point is 1.01-1.06.

[0013] In some embodiments, when the ear clip-on earphone is in its natural state, on the symmetrical surface of the ear hook, there is a sixth reference point on the contour line of the abutment portion that is closest to the first reference point, and the length of the line connecting the first reference point and the sixth reference point is 6-10mm.

[0014] In some embodiments, when the ear clip-on headphones are in their natural state, the arc-to-chord ratio of the inner contour line of the ear clip-on headphones between the first reference point and the sixth reference point is 1.7-2.2 on the ear hook symmetry plane.

[0015] In some embodiments, the ear hook and the sound-emitting part are two-piece sets, and there is a parting line at the assembly point between the two; the outer contour line of the ear clip-on earphone has a seventh reference point that is furthest from the reference tangent, and the seventh reference point is located on the ear hook.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1 As shown, Figure 1This is a schematic diagram of an embodiment of the ear clip-on earphone provided in this application in the wearing state. The user's ear (EAR) may include physiological parts such as the external auditory canal E11, the concha E12, the cymba concha E13, the triangular fossa E14, the antihelix E15, the scaphoid fossa E16, the helix E17, and the antitragus E18. Although the external auditory canal E11 has a certain depth and extends to the tympanic membrane of the ear, for ease of illustration, the ear canal can be interpreted as the external auditory canal E11. The physiological parts such as the concha E12, the cymba concha E13, and the triangular fossa E14 have a certain volume and depth. The concha E12 is directly connected to the external auditory canal E11, which can be simply regarded as the external auditory canal E11 being located at the bottom of the concha E12. Furthermore, the external auditory canal E11 is surrounded by the tragus E19, which is convex.

[0027] In addition, in fields such as medicine and anatomy, three basic planes of the human body can be defined: the sagittal plane, the coronal plane, and the horizontal plane; and three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a plane perpendicular to the ground along the anteroposterior direction of the body, dividing the body into left and right parts. The coronal plane is a plane perpendicular to the ground along the left-right direction of the body, dividing the body into anterior and posterior parts. The horizontal plane is a plane parallel to the ground along the vertical direction of the body, dividing the body into superior and inferior parts. Correspondingly, the sagittal axis is the axis along the anteroposterior direction of the body and perpendicular to the coronal plane; the coronal axis is the axis along the left-right direction of the body and perpendicular to the sagittal plane; and the vertical axis is the axis along the vertical direction of the body and perpendicular to the horizontal plane. Observing the ear (EAR) along the direction of the coronal axis of the human body yields the following... Figure 1 The diagram shows the clip-on earphone 1 in the wearing state. Figure 1 The three directions X, Y, and Z can be simply regarded as the coronal axis, sagittal axis, and vertical axis of the human body, respectively; the three planes XY, XZ, and YZ can be simply regarded as the horizontal plane, coronal plane, and sagittal plane of the human body, respectively.

[0028] Please continue reading. Figure 1The clip-on earphone 1 includes a sound-emitting part 11 for insertion into the concha E12 of the wearer, an abutment part 12 for abutting against the back of the wearer's ear, and an ear hook 13 connecting the sound-emitting part 11 and the abutment part 12. The sound-emitting part 11 can serve as a sound playback device, converting electrical signals into sound signals and playing them to the wearer. The abutment part 12 can serve as a battery compartment for installing batteries or other components. The abutment part 12 and the sound-emitting part 11 form a clamping state so that the entire earphone is clamped and worn on the user's auricle E17. Specifically, the sound-emitting part 11 can abut against the inner wall of the concha E12, and the abutment part 12 can abut against the back of the ear, thereby allowing the clip-on earphone 1 to be clamped and worn on the user's ear around the auricle E17. In some embodiments, the abutment part 12 may not serve as a battery compartment, and the battery may be installed in the sound-emitting part 11.

[0029] The ear hook 13 has an ear hook symmetry plane aa arranged along its length. Specifically, the ear hook symmetry plane aa refers to the plane in which the ear hook 13 is symmetrical about the left and right sides along its length. When the ear hook 13 is an irregular asymmetrical structure, the difference between the ear hooks 13 on both sides of the ear hook symmetry plane aa should be the smallest among various division methods.

[0030] like Figure 2 and Figure 3 As shown, Figure 2 yes Figure 1 The diagram shown is a cross-sectional view of the ear hook symmetry plane when the ear clip-on headphones are in their natural state. Figure 3 This is a cross-sectional schematic diagram along the ear hook symmetry plane of another embodiment of the ear clip-on earphone provided in this application in its natural state. When the ear clip-on earphone 1 is in its natural state, on the ear hook symmetry plane aa, the ear clip-on earphone 1 has a reference tangent line L1. The outline of the sound-emitting part 11 and the outline of the abutment part 12 are tangent to the reference tangent line L1, and the outline of the sound-emitting part 11 and the outline of the abutment part 12 are located on the same side of the reference tangent line L1. The inner outline of the ear hook 13 has a first reference point A that is furthest from the reference tangent line L1. A reference perpendicular line L2 is drawn from the first reference point A to the reference tangent line L1, and the reference perpendicular line L2 passes through the abutment part 12.

[0031] In this application, the "natural state" refers to the state of the ear-clip earphone 1 when it is not subjected to external force. The "wearing state" refers to the state of the ear-clip earphone 1 when it is clipped onto the user's ear. The outline of the sound-emitting part 11 refers to the outline of the cross-section formed by the sound-emitting part 11 on the ear hook symmetry plane aa. The outline of the abutting part 12 refers to the outline of the cross-section formed by the abutting part 12 on the ear hook symmetry plane aa. The inner outline of the ear hook 13 refers to the outline of the side of the ear hook 13 closest to the ear in the wearing state. The inner outline of the ear hook 13 can refer to the outline formed by the inner outline of the ear hook 13 on the ear hook symmetry plane aa. It should be noted that the "outline," "inner outline," and "outer outline" of a part or the whole of the earphone mentioned in this application all refer to the outline of the cross-section formed by that part or the whole on the ear hook symmetry plane aa.

[0032] In the solution of this application, with the length of the ear hook 13 being fixed, by setting a reference vertical line L2 to pass through the abutment part 12, that is, the reference vertical line L2 is offset to the side where the abutment part 12 is located, the inner contour of the ear hook 13 can adapt to the shape of the ear and avoid the auricle E17, which is beneficial to improving wearing comfort.

[0033] like Figure 1 As shown, in some embodiments, the overall shape of the sound-emitting part 11 can be approximately spherical, the shape of the abutment part 12 can be approximately cylindrical, and the ear hook 13 is connected between the abutment part 12 and the sound-emitting part 11. When the ear clip-on earphone 1 is in its natural state, the sound-emitting part 11 and the abutment part 12 can be spaced apart, correspondingly, as... Figure 2 As shown, when the ear clip-on earphone 1 is in its natural state, the sound-emitting part 11 and the contact part 12 are spaced apart on the ear hook symmetry plane aa.

[0034] In some embodiments, when the clip-on earphone 1 is in its natural state, the sound-emitting part 11 and the abutting part 12 can abut against each other. Accordingly, as... Figure 3 As shown, when the ear clip-on earphone 1 is in its natural state, the sound-emitting part 11 and the contact part 12 are at least partially in contact on the ear hook symmetry plane aa.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear clip-on earphone 1 is in its natural state, on the symmetry plane aa of the ear hook, there is a second reference point B closest to the sound-emitting part 11 on the contour line of the abutment part 12, and the distance between the second reference point B and the reference vertical line L2 is 2-8mm. For example, the distance between the second reference point B and the reference vertical line L2 can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, or 8mm.

[0036] like Figure 2As shown, in the natural state, when the sound-emitting part 11 and the contact part 12 are spaced apart from each other, the second reference point B can be the endpoint B of the shortest line Q1B between the sound-emitting part 11 and the contact part 12 on the ear hook symmetry plane aa, which is located on the outline of the contact part 12. The endpoint Q1 is located on the outline of the sound-emitting part 11.

[0037] like Figure 3 As shown, in the natural state, when the sound-producing part 11 and the contact part 12 contact each other, the second reference point B can refer to the midpoint of the arc Q2Q3 formed by the contact area between the sound-producing part 11 and the contact part 12 on the ear hook symmetry plane aa.

[0038] In the solution of this application, by further setting the distance between the second reference point B and the reference vertical line L2 to 2-8mm, the offset of the reference vertical line L2 towards the side where the abutment part 12 is located is controlled within a reasonable range, so that the inner contour of the ear hook 13 can better fit the shape of the ear and avoid the ear helix E17, which is conducive to further improving the wearing comfort.

[0039] like Figure 2 and Figure 3 As shown, in some embodiments, the line connecting the second reference point B and the first reference point A is denoted as the first reference line BA; when the ear clip earphone 1 is in its natural state, on the ear hook symmetry plane aa, there is a third reference point C on the inner contour line of the ear hook 13 that is furthest from the second reference point B, and the line connecting the second reference point B and the third reference point C is denoted as the second reference line BC. The second reference line BC is located on the side of the first reference line BA that is closer to the abutment portion 12.

[0040] In the solution of this application, by setting the second reference line BC to be located on the side of the first reference line BA closer to the abutment 12, the inner contour of the ear hook 13 is shifted to the side where the abutment 12 is located when the length of the ear hook 13 is fixed. This can better fit the shape of the ear and avoid the helix E17, which is conducive to further improving the wearing comfort.

[0041] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear clip-on earphone 1 is in its natural state, the included angle R1 between the first reference connection BA and the second reference connection BC is 8°-25°. For example, the included angle R1 between the first reference connection BA and the second reference connection BC can be 8°, 11°, 13°, 15°, 18°, 20°, or 25°.

[0042] In the solution of this application, by further setting the included angle R1 between the first reference line BA and the second reference line BC to 8°-25°, the offset of the inner contour of the ear hook 13 towards the side where the abutment part 12 is located is controlled within a reasonable range, which can better fit the shape of the ear and avoid the ear helix E17, which is conducive to further improving the wearing comfort.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear clip-on earphone 1 is in its natural state, the angle R2 between the first reference connection line BA and the reference tangent line L1 is 50°-85°. For example, the angle R2 between the first reference connection line BA and the reference tangent line L1 can be 50°, 60°, 65°, 70°, 75°, 80°, or 85°.

[0044] In the solution of this application, by further setting the included angle R2 between the first reference connection line BA and the reference tangent line L1 to 50°-85°, the offset of the inner contour of the ear hook 13 towards the side where the abutment part 12 is located is controlled within a reasonable range, which can better fit the shape of the ear and avoid the ear helix E17, which is conducive to further improving the wearing comfort.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear clip-on earphone 1 is in its natural state, the length of the second reference connection BC is 13-20mm. For example, the length of the second reference connection BC can be 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm.

[0046] In this application, by setting the second reference line BC to be located on the side of the first reference line BA near the abutment portion 12, the included angle between the first reference line BA and the second reference line BC is 8°-25°, and the included angle between the first reference line BA and the reference tangent line L1 is 50°-85°. Furthermore, the length of the second reference line BC is set to 13-20mm. On the one hand, this allows the offset of the inner contour of the ear hook 13 towards the side where the abutment portion 12 is located to be controlled within a reasonable range, which can better fit the shape of the ear and avoid the helix E17, thus improving wearing comfort. On the other hand, it allows the sound-emitting part 11 and the abutment portion 12 to be stably clamped on the ear under the action of the ear hook 13, which helps to improve wearing stability.

[0047] like Figure 2 and Figure 3As shown, in some embodiments, when the ear-clip earphone 1 is in its natural state, on the ear hook symmetry plane aa, the reference vertical line L2 has a first side and a second side that are oppositely arranged, and the sound-emitting part 11 is located on the first side of the reference vertical line L2; on the first side of the reference vertical line L2, the inner contour line of the ear-clip earphone 1 has a fourth reference point D that is furthest from the reference vertical line L2, and the distance between the fourth reference point D and the reference vertical line L2 is denoted as the first distance O1, which is 4-9mm. For example, the first distance O1 can be 4mm, 5mm, 6mm, 7mm, 8mm, or 9mm.

[0048] In the description of this application, the inner contour of the ear-clip earphone 1 can refer to the contour of the ear-clip earphone 1 on the side closest to the ear when worn, and the inner contour line of the ear-clip earphone 1 can refer to the contour line formed by the inner contour of the ear-clip earphone 1 on the ear hook symmetry plane aa. The outer contour of the ear-clip earphone 1 can refer to the contour of the ear-clip earphone 1 on the side away from the ear when worn, and the outer contour line of the ear-clip earphone 1 can refer to the contour line formed by the outer contour of the ear-clip earphone 1 on the ear hook symmetry plane aa.

[0049] like Figure 2 As shown, when the ear clip-on earphone 1 is in its natural state, if the sound-emitting part 11 and the abutment part 12 are spaced apart from each other, the inner and outer contour lines of the ear clip-on earphone 1 can be defined by the two endpoints Q1 and B of the shortest line Q1B between the sound-emitting part 11 and the abutment part 12. The two endpoints Q1 and B divide the entire contour of the ear clip-on earphone 1 into two segments. The curve that is closer to the ear when worn is the inner contour line.

[0050] like Figure 3 As shown, when the ear clip-on earphone 1 is in its natural state, the sound-emitting part 11 and the abutting part 12 abut against each other. The sound-emitting part 11, the abutting part 12, and the ear hook 13 together form a closed space 10. The inner contour line of the ear clip-on earphone 1 can refer to the contour line that forms the closed space 10. The other contour lines of the ear clip-on earphone 1 can be understood as the outer contour lines.

[0051] Please refer to the following: Figure 2 and Figure 4 , Figure 4 yes Figure 1 The diagram shows another example of the clip-on earphone in the wearing state. If the first distance O1 is too small, the inner contour of the clip-on earphone 1 will come into contact with the auricle E17, which may cause pressure on the auricle E17, resulting in poor wearing comfort. If the first distance O1 is too large, it will increase the overall size of the clip-on earphone 1, resulting in a larger overall mass, a shift in the center of gravity, and poorer wearing stability.

[0052] This application sets the first distance O1 to 4-9mm, so that the inner contour of the ear clip earphone 1 can bypass the helix E17 as much as possible, avoiding compression of the helix E17. At the same time, it can also control the overall size of the ear clip earphone 1 within a certain range, thereby improving the wearing comfort and wearing stability of the ear clip earphone 1.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear-clip earphone 1 is in its natural state, on the second side of the reference vertical line L2, there is a fifth reference point E on the inner contour line of the ear-clip earphone 1 that is furthest from the reference vertical line L2. The distance between the fifth reference point E and the reference vertical line L2 is denoted as the second distance O2, which is 7-13 mm. For example, the second distance O2 can be 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, or 13 mm.

[0054] Please refer to the following: Figure 2 and Figure 4 If the second distance O2 is too small, the inner contour of the ear clip earphone 1 will come into contact with the antihelix E15, which will easily cause pressure on the antihelix E15, resulting in poor wearing comfort; if the second distance O2 is too large, it will increase the overall size of the ear clip earphone 1, resulting in a larger overall weight of the ear clip earphone 1 and poorer wearing stability.

[0055] By setting the second distance O2 to 7-13mm, this application allows the inner contour of the ear clip earphone 1 to bypass the antihelix E15 as much as possible, avoiding compression of the antihelix E15. At the same time, it can also control the overall size of the ear clip earphone 1 within a certain range, thereby improving the wearing comfort and wearing stability of the ear clip earphone 1.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear-clip earphone 1 is in its natural state, on the ear hook symmetry plane aa, the arc-chord ratio between the first reference point A and the fourth reference point D of the inner contour line of the ear-clip earphone 1 is 1.08-1.20, for example, it can be 1.08, 1.10, 1.12, 1.14, 1.16, 1.18, or 1.20; the arc-chord ratio between the first reference point A and the fifth reference point E of the inner contour line of the ear-clip earphone 1 is 1.01-1.06, for example, it can be 1.01, 1.02, 1.03, 1.04, 1.05, or 1.06.

[0057] This application sets the first distance O1 to 4-9mm, the second distance O2 to 7-13mm, and further sets the arc-chord ratio of the inner contour line of the ear clip earphone 1 between the first reference point A and the fourth reference point D to 1.08-1.20, and the arc-chord ratio of the inner contour line of the ear clip earphone 1 between the first reference point A and the fifth reference point E to 1.01-1.06. This allows it to better fit the shape of the ear and avoid the helix E17 and the antihelix E15, which is beneficial to improving wearing comfort.

[0058] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear clip-on earphone 1 is in its natural state, on the symmetry plane aa of the ear hook, the contour line of the abutment portion 12 has a sixth reference point F that is closest to the first reference point A, and the length of the line AF connecting the first reference point A and the sixth reference point F is 6-10mm. For example, the length of the line AF can be 6mm, 7mm, 8mm, 9mm, or 10mm.

[0059] If the length of the connecting wire AF is too short, the inner contour of the ear hook 13 will come into contact with the edge 1071 of the ear helix E17 when worn, and / or the abutment part 12 will come into contact with the rear side 1072 of the ear helix E17, which may easily cause pressure on the ear helix; if the length of the connecting wire AF is too long, it will increase the overall size of the ear clip earphone 1, resulting in a larger overall weight of the ear clip earphone 1, a shift in the center of gravity, and a decrease in wearing stability.

[0060] This application sets the length of the connecting line AF to 6-10mm, so that the inner contour of the ear hook 13 can bypass the ear helix E17 as much as possible, avoiding compression of the ear helix E17. At the same time, it can also control the overall size of the ear clip earphone 1 within a certain range, thereby improving the wearing comfort and wearing stability of the ear clip earphone 1.

[0061] like Figure 2 As shown, in some embodiments, when the ear clip earphone 1 is in its natural state, on the ear hook symmetry plane aa, the arc-chord ratio between the first reference point A and the sixth reference point F of the inner contour line of the ear clip earphone 1 is 1.7-2.2, for example, it can be 1.7, 1.8, 1.9, 2.0, 2.1 or 2.2.

[0062] If the arc-to-chord ratio between the inner contour of the ear clip earphone 1 and the first reference point A and the sixth reference point F is too small, the inner contour of the ear clip earphone 1 will come into contact with the helix E17, which will easily cause compression of the helix E17, resulting in poor wearing comfort. If the arc-to-chord ratio is too large, it will increase the overall size of the ear clip earphone 1, resulting in a larger overall mass of the ear clip earphone 1 and a poorer wearing stability.

[0063] By setting the arc-to-chord ratio between the first reference point A and the sixth reference point F of the inner contour line of the ear clip earphone 1 between 1.7 and 2.2, the inner contour of the ear clip earphone 1 can better bypass the helix E17, avoiding compression of the helix E17. At the same time, the overall size of the ear clip earphone 1 can be controlled within a certain range, which is conducive to improving the wearing comfort and wearing stability of the ear clip earphone 1.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments, the ear hook 13 includes a support rib 132 and a flexible body 133 that wraps around the support rib 132. The support rib 132 is an elastic metal sheet or an elastic metal wire, and includes a first end 1321 and a second end 1322 disposed opposite to each other. The first end 1321 of the support rib 132 is connected to the sound-emitting part 11, and the second end 1322 of the support rib 132 is connected to the abutment part 12. In this case, the position of the first end 1321 of the support rib 132 can be understood as the boundary between the ear hook 13 and the sound-emitting part 11, and the position of the second end 1322 of the support rib 132 can be understood as the boundary between the ear hook 13 and the abutment part 12. That is to say, it can be understood that each segment of the ear hook 13 includes a support rib 132 and a flexible body 133 that wraps around the support rib 132, thereby determining the boundary between the ear hook 13 and the sound-emitting part 11 or the abutment part 12.

[0065] In some embodiments, the ear hook 13 may not simultaneously include the support rib 132 and the flexible body 133, but it still has a certain degree of elasticity. For example, the sound-emitting part 11 includes a plastic shell with a certain strength to protect the components disposed therein, while the ear hook 13 is elastic and can deform to provide clamping force and ensure stability when worn. In this case, the part that can undergo elastic deformation can be understood as the ear hook 13, and the part that cannot undergo elastic deformation can be understood as the sound-emitting part 11 or the abutment part 12. That is to say, it can be understood that each segment of the ear hook 13 is elastic, thereby determining the boundary between the ear hook 13 and the sound-emitting part 11 or the abutment part 12.

[0066] like Figure 5 As shown, Figure 5 This is a three-dimensional schematic diagram of another embodiment of the ear clip-on headphones provided in this application in its natural state. In some embodiments, the ear hook 13 and the sound-emitting part 11 are provided as two pieces, and there is a first parting line 14 at the assembly point between the two. In this case, the position of the first parting line 14 can be understood as the boundary between the ear hook 13 and the sound-emitting part 11.

[0067] In some embodiments, the ear hook 13 and the abutment portion 12 are provided as two pieces, and there is a second parting line at the assembly point between the two. In this case, the location of the second parting line can be understood as the boundary between the ear hook 13 and the abutment portion 12.

[0068] like Figure 2 and Figure 3 As shown, the outer contour of the ear clip-on earphone 1 has a seventh reference point G that is furthest from the reference tangent line L1, and the seventh reference point G can be located on the ear hook 13. In the solution of this application, by setting the seventh reference point G on the ear hook 13, it is beneficial to control the overall size of the ear clip-on earphone 1, thereby improving the wearing stability.

[0069] like Figure 2 and Figure 3 As shown, in some embodiments, when the ear clip earphone 1 is in its natural state, the angle between the line L3 connecting the two opposite ends of the ear hook 13 and the reference tangent L1 on the ear hook symmetry plane aa is less than or equal to 45°. For example, the angle between the line L3 connecting the two opposite ends of the ear hook 13 and the reference tangent L1 can be 10°, 20°, 30°, 40°, or 45°.

[0070] In the solution of this application, by setting the angle between the line L3 connecting the two ends of the ear hook 13 and the reference tangent L1 to be less than or equal to 45°, the inner contour of the ear hook 13 can adapt to the shape of the ear, thereby further improving the wearing comfort.
