[0019] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work, among which: Figure 1 is a schematic diagram of an embodiment of the ear-clip earphone provided by the present application in a wearing state; Figure 2 is a cross-sectional schematic diagram along the earhook symmetry plane of the earhook when the ear-clip earphone shown in Figure 1 is in a natural state; Figure 3 is a cross-sectional schematic diagram along the earhook symmetry plane of another embodiment of the ear-clip earphone provided by the present application in a natural state; Figure 4 is another schematic diagram of the ear-clip earphone shown in Figure 1 in a wearing state; Figure 5 is a three-dimensional schematic diagram of another embodiment of the ear-clip earphone provided by the present application in a natural state. [Specific implementation method]

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] As shown in Figure 1, Figure 1 is a schematic diagram of an embodiment of the ear clip earphone provided by the present application in the wearing state. The user's ear EAR may include physiological parts such as the external auditory canal E11, the cavum concha E12, the cymba concha E13, the triangular fossa E14, the antihelix E15, the scaphoid E16, the helix E17 and the antitragus E18. Among them, although the external auditory canal E11 has a certain depth and extends to the eardrum of the ear, for the convenience of illustration, the ear hole can be interpreted as the external auditory canal E11. Physiological parts such as the cavum concha E12, the cymba concha E13 and the triangular fossa E14 have a certain volume and depth. The cavum concha E12 is directly connected to the external auditory canal E11, that is, the external auditory canal E11 can be simply regarded as being located at the bottom of the cavum concha E12. Furthermore, the outer periphery of the external auditory canal E11 also includes the tragus E19, which is convex.

[0022] In addition, in fields such as medicine and anatomy, the three basic planes of the human body are defined: the sagittal plane, the coronal plane, and the horizontal plane; and the three basic axes: the sagittal axis, the coronal axis, and the vertical axis. The sagittal plane is a plane perpendicular to the ground, drawn along the front-to-back direction of the body, dividing the body into left and right parts; the coronal plane is a plane perpendicular to the ground, drawn along the left-to-right direction of the body, dividing the body into front and back parts; and the horizontal plane is a plane parallel to the ground, drawn along the top-to-bottom direction of the body, dividing the body into top and bottom parts. Accordingly, the sagittal axis is an axis along the front-to-back direction of the body and perpendicular to the coronal plane; the coronal axis is an axis along the left-to-right direction of the body and perpendicular to the sagittal plane; and the vertical axis is an axis along the top-to-bottom direction of the body and perpendicular to the horizontal plane. Observing the ear along the direction of the coronal axis yields a schematic diagram of the ear clip-on headphone 1 in its worn state, as shown in Figure 1. In FIG1 , the three directions X, Y and Z can be simply regarded as the human body coronal axis, human body sagittal axis and human body vertical axis respectively; the three planes XY, XZ and YZ can be simply regarded as the human body horizontal plane, human body coronal plane and human body sagittal plane respectively.

[0023] Continuing with Figure 1, the ear clip-on earphone 1 includes a sound-producing portion 11 for insertion into the wearer's cavum concha E12, a contact portion 12 for contacting the back of the wearer's ear, and an ear hook 13 connecting the sound-producing portion 11 and the contact portion 12. The sound-producing portion 11 can function as a sound playback device, converting electrical signals into acoustic signals and playing them back to the wearer. The contact portion 12 can also serve as a battery compartment for batteries or other components. The contact portion 12 and the sound-producing portion 11 form a clamping structure, allowing the entire earphone to be worn around the wearer's helix E17. Specifically, the sound-producing portion 11 can contact the inner wall of the cavum concha E12, and the contact portion 12 can contact the back of the ear, allowing the ear clip-on earphone 1 to bypass the helix E17 and be clamped to the wearer's ear. In some embodiments, the contact portion 12 can function as a battery compartment rather than a battery compartment, with the battery installed in the sound-producing portion 11.

[0024] The ear hook 13 has an ear hook symmetry plane aa along its length. Specifically, the ear hook symmetry plane aa is a plane that is bilaterally symmetrical along its length. When the ear hook 13 has an asymmetrical structure, the difference between the ear hooks 13 on either side of the ear hook symmetry plane aa should be the smallest among all classification methods.

[0025] As shown in Figures 2 and 3, Figure 2 is a schematic cross-sectional view of the ear clip earphone shown in Figure 1 in its natural state along the ear hook symmetry plane, and Figure 3 is a schematic cross-sectional view of another embodiment of the ear clip earphone provided by the present application in its natural state along the ear hook symmetry plane. When the ear clip earphone 1 is in its natural state, on the ear hook symmetry plane aa, the ear clip earphone 1 has a reference tangent line L1. The contour lines of the sound-emitting portion 11 and the abutting portion 12 are respectively tangent to the reference tangent line L1, and the contour lines of the sound-emitting portion 11 and the abutting portion 12 are located on the same side of the reference tangent line L1. The inner contour line of the ear hook 13 has a first reference point A farthest 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 abutting portion 12.

[0026] The "natural state" described in this application refers to the state of the ear-clip earphone 1 when it is not subjected to external forces. The "worn state" described in this application refers to the state of the ear-clip earphone 1 when it is clamped and worn on the user's ear. The contour line of the sound-emitting portion 11 refers to the contour line of the cross section formed by the sound-emitting portion 11 on the earhook symmetry plane aa. The contour line of the abutting portion 12 refers to the contour line of the cross section formed by the abutting portion 12 on the earhook symmetry plane aa. The inner contour of the earhook 13 refers to the contour of the side of the earhook 13 closest to the ear when worn. The inner contour line of the earhook 13 may refer to the contour line formed by the inner contour of the earhook 13 on the earhook symmetry plane aa. It should be noted that the "contour line," "inner contour line," and "outer contour line" of a part or the entire earphone mentioned in this application all refer to the contour line of the cross section formed by that part or the entirety on the earhook symmetry plane aa.

[0027] In the solution of the present application, when the length of the ear hook 13 is constant, by setting a reference vertical line L2 to pass through the abutment portion 12, that is, the reference vertical line L2 is offset to the side where the abutment portion 12 is located, the inner contour of the ear hook 13 can adapt to the shape of the ear, avoid the auricle E17, which is conducive to improving wearing comfort.

[0028] As shown in FIG1 , in some embodiments, the overall shape of the sound-emitting portion 11 can be approximately spherical, the shape of the abutting portion 12 can be approximately cylindrical, and the ear hook 13 is connected between the abutting portion 12 and the sound-emitting portion 11. When the ear clip-on headphone 1 is in a natural state, the sound-emitting portion 11 and the abutting portion 12 can be spaced apart. Accordingly, as shown in FIG2 , when the ear clip-on headphone 1 is in a natural state, the sound-emitting portion 11 and the abutting portion 12 are spaced apart on the ear hook symmetry plane aa.

[0029] In some embodiments, when the ear clip-on headphone 1 is in its natural state, the sound-emitting portion 11 and the abutting portion 12 may abut against each other. Accordingly, as shown in FIG3 , when the ear clip-on headphone 1 is in its natural state, the sound-emitting portion 11 and the abutting portion 12 at least partially contact each other on the earhook symmetry plane aa.

[0030] As shown in Figures 2 and 3 , in some embodiments, when the ear clip earphone 1 is in a neutral position, the contour line of the abutment portion 12 on the earhook symmetry plane aa has a second reference point B closest to the sound-emitting portion 11. The distance between the second reference point B and the reference vertical line L2 is 2-8 mm. For example, the distance between the second reference point B and the reference vertical line L2 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm.

[0031] As shown in Figure 2, in the natural state, when the sound-emitting part 11 and the abutting part 12 are spaced from each other, the second reference point B can refer to the endpoint B of the shortest connecting line Q1B between the sound-emitting part 11 and the abutting part 12 on the ear hook symmetry plane aa, which is located on the contour line of the abutting part 12, and the endpoint Q1 is located on the contour line of the sound-emitting part 11.

[0032] As shown in FIG3 , in a natural state, when the sound-emitting part 11 and the abutting part 12 abut against each other, the second reference point B may refer to the midpoint of the arc Q2Q3 formed by the abutting area between the sound-emitting part 11 and the abutting part 12 on the ear hook symmetry plane aa.

[0033] In the solution of the present application, by further setting the distance between the second reference point B and the reference vertical line L2 to 2-8 mm, the offset of the reference vertical line L2 to the side where the abutment portion 12 is located is controlled within a reasonable range, so that the inner contour of the ear hook 13 can be more adapted to the shape of the ear, avoiding the auricle E17, which is conducive to further improving wearing comfort.

[0034] As shown in Figures 2 and 3, in some embodiments, the line between the second reference point B and the first reference point A is recorded as the first reference line BA; when the ear clip earphone 1 is in a natural state, on the ear hook symmetry plane aa, the inner contour line of the ear hook 13 has a third reference point C that is farthest from the second reference point B, and the line between the second reference point B and the third reference point C is recorded as the second reference line BC. The second reference line BC is located on the side of the first reference line BA close to the abutting portion 12.

[0035] In the solution of the present application, by setting the second reference line BC to be located on the side of the first reference line BA close to the abutment portion 12, when the length of the ear hook 13 is constant, the inner contour of the ear hook 13 is offset as a whole toward the side where the abutment portion 12 is located, which can better adapt to the shape of the ear and avoid the auricle E17, which is conducive to further improving wearing comfort.

[0036] As shown in FIG2 and FIG3 , in some embodiments, when the ear clip earphone 1 is in a neutral state, the angle R1 between the first reference line BA and the second reference line BC is 8°-25°. For example, the angle R1 between the first reference line BA and the second reference line BC can be 8°, 11°, 13°, 15°, 18°, 20°, or 25°.

[0037] In the solution of the present application, by further setting the 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 to the side where the abutment portion 12 is located is controlled within a reasonable range, which can better adapt to the shape of the ear and avoid the auricle E17, which is conducive to further improving wearing comfort.

[0038] As shown in FIG2 and FIG3 , in some embodiments, when the ear clip earphone 1 is in a neutral state, the angle R2 between the first reference line BA and the reference tangent line L1 is 50°-85°. For example, the angle R2 between the first reference line BA and the reference tangent line L1 can be 50°, 60°, 65°, 70°, 75°, 80°, or 85°.

[0039] In the solution of the present application, by further setting the angle R2 between the first reference line BA and the reference tangent line L1 to 50°-85°, the offset of the inner contour of the ear hook 13 to the side where the abutment portion 12 is located is controlled within a reasonable range, which can better adapt to the shape of the ear and avoid the auricle E17, which is conducive to further improving wearing comfort.

[0040] As shown in FIG2 and FIG3 , in some embodiments, when the ear clip earphone 1 is in a natural state, the length of the second reference line BC is 13-20 mm. For example, the length of the second reference line BC can be 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, or 20 mm.

[0041] In the solution of the present application, by setting the second reference line BC to be located on the side of the first reference line BA close to the abutment 12, the angle between the first reference line BA and the second reference line BC is 8°-25°, the angle between the first reference line BA and the reference tangent L1 is 50°-85°, and the length of the second reference line BC is further set to 13-20mm. On the one hand, the offset of the inner contour of the ear hook 13 to the side where the abutment 12 is located is controlled within a reasonable range, which can better adapt to the shape of the ear and avoid the helix E17, which is beneficial to improving wearing comfort. On the other hand, the sound-emitting part 11 and the abutment 12 can be stably clamped on the ear under the action of the ear hook 13, which is beneficial to improving wearing stability.

[0042] As shown in FIG2 and FIG3 , in some embodiments, when the ear clip earphone 1 is in a neutral position, on the earhook symmetry plane aa, a reference vertical line L2 has a first side and a second side opposite each other, and the sound-emitting portion 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 farthest from the reference vertical line L2. The distance between the fourth reference point D and the reference vertical line L2 is denoted as a first distance O1, and the first distance O1 is in a range of 4-9 mm. For example, the first distance O1 can be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or 9 mm.

[0043] In the description of this application, the inner contour of the ear clip earphone 1 may refer to the contour of the side of the ear clip earphone 1 close to the ear when worn, and the inner contour line of the ear clip earphone 1 may refer to the contour line formed by the inner contour of the ear clip earphone 1 on the earhook symmetry plane aa. The outer contour of the ear clip earphone 1 may refer to the contour of the side of the ear clip earphone 1 away from the ear when worn, and the outer contour line of the ear clip earphone 1 may refer to the contour line formed by the outer contour of the ear clip earphone 1 on the earhook symmetry plane aa.

[0044] As shown in FIG2 , when the ear clip-on headphone 1 is in its natural state, if the sound-emitting portion 11 and the abutting portion 12 are spaced apart from each other, the inner and outer contours of the ear clip-on headphone 1 can be defined by the two endpoints Q1 and B of the shortest line Q1B between the sound-emitting portion 11 and the abutting portion 12. These two endpoints Q1 and B divide the entire contour of the ear clip-on headphone 1 into two segments, and the curve that is closer to the ear when worn is the inner contour.

[0045] As shown in FIG3 , when the ear clip-on headphone 1 is in a natural state, the sound-emitting portion 11 and the abutting portion 12 abut against each other. The sound-emitting portion 11, the abutting portion 12, and the ear hook 13 collectively enclose a closed space 10. The inner contour of the ear clip-on headphone 1 may refer to the contour that encloses the closed space 10. The remaining contours of the ear clip-on headphone 1 may be understood as the outer contours.

[0046] Please refer to Figures 2 and 4 . Figure 4 is another schematic diagram of the ear clip earphone shown in Figure 1 when worn. If the first distance O1 is too small, the inner contour of the ear clip earphone 1 will contact the helix E17, easily squeezing the helix E17 and causing poor wearing comfort. If the first distance O1 is too large, the overall size of the ear clip earphone 1 will increase, resulting in an increase in overall mass, a shift in the center of gravity, and poor wearing stability.

[0047] In the present application, by setting the first distance O1 to 4-9 mm, the inner contour of the ear clip earphone 1 can bypass the helix E17 as much as possible to avoid squeezing 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.

[0048] As shown in FIG2 and FIG3 , in some embodiments, when the ear clip earphone 1 is in a neutral position, a fifth reference point E is located on the inner contour line of the ear clip earphone 1, on the second side of the reference vertical line L2, and is farthest 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. The second distance O2 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.

[0049] Please refer to Figures 2 and 4 together. 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 may easily squeeze the antihelix E15 and cause poor wearing comfort. If the second distance O2 is too large, the overall size of the ear clip earphone 1 will increase, resulting in an increase in the overall mass of the ear clip earphone 1 and poor wearing stability.

[0050] In the present application, by setting the second distance O2 to 7-13 mm, the inner contour of the ear clip earphone 1 can bypass the antihelix E15 as much as possible, avoiding squeezing the antihelix E15. At the same time, the overall size of the ear clip earphone 1 can be controlled within a certain range, thereby facilitating improved wearing comfort and stability of the ear clip earphone 1.

[0051] As shown in Figures 2 and 3, in some embodiments, when the ear clip-on earphone 1 is in a natural state, on the ear hook symmetry plane aa, the arc-chord ratio of the inner contour line of the ear clip-on earphone 1 between the first reference point A and the fourth reference point D 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 of the inner contour line of the ear clip-on earphone 1 between the first reference point A and the fifth reference point E is 1.01-1.06, for example, it can be 1.01, 1.02, 1.03, 1.04, 1.05, or 1.06.

[0052] The present application sets the first distance O1 to 4-9 mm, the second distance O2 to 7-13 mm, 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. These configurations can better adapt to the shape of the ear, avoid the antihelix E17 and the antihelix E15, and improve wearing comfort.

[0053] As shown in FIG2 and FIG3 , in some embodiments, when the ear clip-on headphone 1 is in a neutral position, the contour line of the abutting portion 12 on the earhook symmetry plane aa includes a sixth reference point F closest to the first reference point A. The length of the line AF between the first reference point A and the sixth reference point F is 6-10 mm. For example, the length of the line AF can be 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0054] If the length of the connection line AF is too short, the inner contour of the ear hook 13 may come into contact with the edge 1071 of the helix E17 when worn, and / or the abutment portion 12 may come into contact with the rear side 1072 of the helix E17, which may easily cause squeezing of the helix; if the length of the connection line AF is too long, the overall size of the ear clip-on earphone 1 may be increased, resulting in an increase in the overall mass of the ear clip-on earphone 1, a shift in the center of gravity, and poor wearing stability.

[0055] The present application sets the length of the connection line AF to 6-10 mm, so that the inner contour of the ear hook 13 can bypass the helix E17 as much as possible to avoid squeezing 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.

[0056] As shown in FIG2 , in some embodiments, when the ear clip-on earphone 1 is in a natural state, on the ear hook symmetry plane aa, the arc-chord ratio of the inner contour line of the ear clip-on earphone 1 between the first reference point A and the sixth reference point F is 1.7-2.2, for example, it can be 1.7, 1.8, 1.9, 2.0, 2.1, or 2.2.

[0057] If the arc-chord ratio of the inner contour line of the ear clip-on earphone 1 between the first reference point A and the sixth reference point F is too small, the inner contour of the ear clip-on earphone 1 will come into contact with the helix E17, which may easily squeeze the helix E17 and cause poor wearing comfort; if the arc-chord ratio is too large, the overall size of the ear clip-on earphone 1 will be increased, resulting in an increase in the overall mass of the ear clip-on earphone 1 and poor wearing stability.

[0058] By setting the arc-chord ratio of the inner contour line of the ear-clip earphone 1 between the first reference point A and the sixth reference point F to be between 1.7 and 2.2, the inner contour of the ear-clip earphone 1 can better bypass the helix E17, avoiding squeezing 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.

[0059] As shown in Figures 2 and 3, 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 elastic metal wire and includes a first end 1321 and a second end 1322 that are oppositely disposed. The first end 1321 of the support rib 132 is connected to the sound-emitting portion 11, and the second end 1322 of the support rib 132 is connected to the abutment portion 12. In this case, the location 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 portion 11, and the location of the second end 1322 of the support rib 132 can be understood as the boundary between the ear hook 13 and the abutment portion 12. In other words, it can be understood that each section 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 portion 11 or the abutment portion 12.

[0060] In some embodiments, the ear hook 13 may not include both the support ribs 132 and the flexible body 133, but may also have a certain degree of elasticity. For example, the sound-emitting portion 11 includes a plastic shell that has a certain strength to protect the components disposed therein, while the ear hook 13 is elastic and can deform to provide a clamping force to ensure stability when worn. In this case, the portion that can undergo elastic deformation can be understood as the ear hook 13, and the portion that cannot undergo elastic deformation can be understood as the sound-emitting portion 11 or the abutting portion 12. In other words, it can be understood that each section of the ear hook 13 is elastic, thereby determining the boundary between the ear hook 13 and the sound-emitting portion 11 or the abutting portion 12.

[0061] As shown in Figure 5, Figure 5 is a three-dimensional schematic diagram of another embodiment of the ear clip-type earphone provided by the present application in a natural state. In some embodiments, the ear hook 13 and the sound-emitting part 11 are arranged in two parts, and there is a first parting line 14 at the assembly point between the two. At this time, 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.

[0062] In some embodiments, the ear hook 13 and the abutment portion 12 are provided in two pieces, and a second parting line exists at the assembly point between the two. In this case, the position of the second parting line can be understood as the boundary between the ear hook 13 and the abutment portion 12.

[0063] As shown in Figures 2 and 3, the outer contour of the ear clip-on headphone 1 has a seventh reference point G that is farthest from the reference tangent line L1. The seventh reference point G can be located on the ear hook 13. In the solution of the present application, by placing the seventh reference point G on the ear hook 13, it is helpful to control the overall size of the ear clip-on headphone 1, thereby improving wearing stability.

[0064] As shown in Figures 2 and 3, in some embodiments, when the ear clip earphone 1 is in a natural state, on the ear hook symmetry plane aa, the angle between the line L3 connecting the opposite ends of the ear hook 13 and the reference tangent L1 is less than or equal to 45°. For example, the angle between the line L3 connecting the opposite ends of the ear hook 13 and the reference tangent L1 can be 10°, 20°, 30°, 40°, or 45°.

[0065] In the solution of the present application, by setting the angle between the line L3 connecting the opposite 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, further improving the wearing comfort.
