DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the sake of description, only the parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0021] As Figure 1 shown, Figure 1FIG. 0 is a schematic diagram of an earclip-type earphone provided by the present application in a worn state. The user's ear EAR may include physiological parts such as the external auditory canal E11, the concha E12, the cymba conchae E13, the triangular fossa E14, the antihelix E15, the scaphoid fossa 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 earhole can be understood as the external auditory canal E11. The physiological parts such as the concha E12, the cymba conchae E13, and the triangular fossa E14 have a certain volume and depth. The concha E12 is directly connected to the external auditory canal E11, that is, it can be simply considered that the external auditory canal E11 is located at the bottom of the concha E12. Further, the tragus E19 is also included outside the external auditory canal E11, and the tragus E19 is convex.

[0022] In addition, in the fields of medicine, anatomy, etc., three basic sections of the human body, namely the sagittal plane, the coronal plane, and the horizontal plane, and three basic axes, namely the sagittal axis, the coronal axis, and the vertical axis, can be defined. Among them, the sagittal plane is a vertical section made along the front-back direction of the body and perpendicular to the ground, which divides the human body into left and right parts; the coronal plane is a vertical section made along the left-right direction of the body and perpendicular to the ground, which divides the human body into front and back parts; the horizontal plane is a horizontal section made along the up-down direction of the body and parallel to the ground, which divides the human body into upper and lower parts. Correspondingly, the sagittal axis is an axis along the front-back direction of the body and perpendicular to the coronal plane, the coronal axis is an axis along the left-right direction of the body and perpendicular to the sagittal plane, and the vertical axis is an axis along the up-down direction of the body and perpendicular to the horizontal plane. Observing the ear EAR along the direction of the human coronal axis, a schematic diagram of the earclip-type earphone 1 in a worn state as shown in Figure 1 can be obtained. Figure 1 In FIG., the three directions of X, Y, and Z can be simply regarded as the human coronal axis, the human sagittal axis, and the human vertical axis respectively; the three planes of XY, XZ, and YZ can be simply regarded as the human horizontal plane, the human coronal plane, and the human sagittal plane respectively.

[0023] Please continue to refer to Figure 1, the earclip-type earphone 1 includes a sound-emitting part 11 for inserting into the concha cavity E12 of the wearer, a abutting part 12 for abutting against the back of the wearer's ear, and an earhook 13 connecting the sound-emitting part 11 and the abutting part 12. The sound-emitting part 11 can be used as a sound-playing device, which is used to convert an electrical signal into a sound signal and play it to the wearer. The abutting part 12 can be used as a battery compartment for installing a battery or other components. The abutting part 12 and the sound-emitting part 11 form a clamping state so as to clamp and wear the whole earphone on the helix E17 of the user. Specifically, the sound-emitting part 11 can abut against the inner wall of the concha cavity E12, and the abutting part 12 can abut against the back of the ear, so that the earclip-type earphone 1 bypasses the helix E17 and is clamped and worn on the user's ear. In some embodiments, the abutting part 12 may not be used as a battery compartment, and the battery is installed in the sound-emitting part 11.

[0024] Among them, the earhook 13 has an earhook symmetry plane a-a arranged along its length direction. Specifically, the earhook symmetry plane a-a refers to the plane where the earhook 13 is symmetric left and right along its length direction. When the earhook 13 is a special-shaped asymmetric structure, the difference between the two sides of the earhook 13 on the earhook symmetry plane a-a should be the smallest among various division methods.

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

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

[0027] In the solution of this application, when the length of the earhook 13 is fixed, by setting the reference perpendicular line L2 to pass through the abutting part 12, that is, the reference perpendicular line L2 is offset toward the side where the abutting part 12 is located, the inner contour of the earhook 13 can be adapted to the shape of the ear, avoiding the helix E17, which is beneficial to improving the wearing comfort.

[0028] As Figure 1 shown, in some embodiments, the overall shape of the sound-emitting part 11 can be approximately spherical, the shape of the abutting part 12 can be approximately cylindrical, and the earhook 13 is connected between the abutting part 12 and the sound-emitting part 11. When the earclip-type earphone 1 is in the natural state, the sound-emitting part 11 and the abutting part 12 can be arranged at intervals. Correspondingly, as Figure 2 shown, when the earclip-type earphone 1 is in the natural state, on the earhook symmetry plane a-a, the sound-emitting part 11 and the abutting part 12 are arranged at intervals.

[0029] In some embodiments, when the earclip-type earphone 1 is in the natural state, the sound-emitting part 11 and the abutting part 12 can be in contact with each other. Correspondingly, as Figure 3 shown, when the earclip-type earphone 1 is in the natural state, on the earhook symmetry plane a-a, the sound-emitting part 11 and the abutting part 12 are at least partially in contact.

[0030] As Figure 2 and Figure 3 shown, in some embodiments, when the earclip-type earphone 1 is in the natural state, on the earhook symmetry plane a-a, there is a second reference point B on the contour line of the abutting part 12 that is closest to the sound-emitting part 11, and the distance between the second reference point B and the reference perpendicular line L2 is 2-8 mm. For example, the distance between the second reference point B and the reference perpendicular line L2 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm.

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

[0032] As Figure 3 shown, when the sound - generating part 11 and the abutting part 12 are in abutment with each other in the natural state, the second reference point B can refer to the mid - point of the arc Q2Q3 formed by the abutting area between the sound - generating part 11 and the abutting part 12 on the ear - hook symmetry plane a - a.

[0033] In the solution of the present application, by further setting the distance between the second reference point B and the reference perpendicular line L2 to be 2 - 8 mm, the offset of the reference perpendicular line L2 towards the side where the abutting 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, avoiding the antihelix E17, which is beneficial to further improve the wearing comfort.

[0034] As Figure 2 and Figure 3 shown, in some embodiments, the connecting line between the second reference point B and the first reference point A is denoted as the first reference connecting line BA; when the ear - clip type earphone 1 is in the natural state, on the ear - hook symmetry plane a - a, there is a third reference point C on the inner contour line of the ear - hook 13 that is farthest from the second reference point B, and the connecting line between the second reference point B and the third reference point C is denoted as the second reference connecting line BC, and the second reference connecting line BC is on the side of the first reference connecting line BA closer to the abutting part 12.

[0035] In the solution of the present application, by setting the second reference connecting line BC on the side of the first reference connecting line BA closer to the abutting part 12, when the length of the ear - hook 13 is fixed, the inner contour of the ear - hook 13 is offset as a whole towards the side where the abutting part 12 is located, which can better fit the shape of the ear, avoiding the antihelix E17, and is beneficial to further improve the wearing comfort.

[0036] As Figure 2 and Figure 3 shown, in some embodiments, when the ear - clip type earphone 1 is in the natural state, the included angle R1 between the first reference connecting line BA and the second reference connecting line BC is 8° - 25°. For example, the included angle R1 between the first reference connecting line BA and the second reference connecting 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 connection line BA and the second reference connection line BC to be 8° - 25°, the offset of the inner contour of the earhook 13 towards the side where the abutting portion 12 is located is controlled within a reasonable range, enabling better adaptation to the shape of the ear, avoiding the helix E17, and being conducive to further improving the wearing comfort.

[0038] As Figure 2 and Figure 3 shown, in some embodiments, when the earclip-type earphone 1 is in the 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°.

[0039] In the solution of the present application, by further setting the angle R2 between the first reference connection line BA and the reference tangent line L1 to be 50° - 85°, the offset of the inner contour of the earhook 13 towards the side where the abutting portion 12 is located is controlled within a reasonable range, enabling better adaptation to the shape of the ear, avoiding the helix E17, and being conducive to further improving the wearing comfort.

[0040] As Figure 2 and Figure 3 shown, in some embodiments, when the earclip-type earphone 1 is in the natural state, the length of the second reference connection line BC is 13 - 20 mm. For example, the length of the second reference connection 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 connection line BC on the side of the first reference connection line BA closer to the abutting portion 12, the angle between the first reference connection line BA and the second reference connection line BC is 8° - 25°, the angle between the first reference connection line BA and the reference tangent line L1 is 50° - 85°, and further setting the length of the second reference connection line BC to be 13 - 20 mm, on the one hand, the offset of the inner contour of the earhook 13 towards the side where the abutting portion 12 is located is controlled within a reasonable range, enabling better adaptation to the shape of the ear, avoiding the helix E17, and being conducive to improving the wearing comfort. On the other hand, the sound generating portion 11 and the abutting portion 12 can be stably clamped on the ear under the action of the earhook 13, which is conducive to improving the wearing stability.

[0042] As Figure 2 and Figure 3As shown, in some embodiments, when the earclip-type earphone 1 is in a natural state, on the earhook symmetry plane a-a, the reference perpendicular line L2 has a first side and a second side that are relatively arranged, and the sound-emitting part 11 is located on the first side of the reference perpendicular line L2; on the first side of the reference perpendicular line L2, there is a fourth reference point D on the inner contour line of the earclip-type earphone 1 that is farthest from the reference perpendicular line L2, and the distance between the fourth reference point D and the reference perpendicular line L2 is denoted as the first distance O1, and the first distance O1 is 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 the present application, the inner contour of the earclip-type earphone 1 may refer to the contour on the side of the earclip-type earphone 1 close to the ear in the worn state, and the inner contour line of the earclip-type earphone 1 may refer to the contour line formed by the inner contour of the earclip-type earphone 1 on the earhook symmetry plane a-a. The outer contour of the earclip-type earphone 1 may refer to the contour on the side of the earclip-type earphone 1 facing away from the ear in the worn state, and the outer contour line of the earclip-type earphone 1 may refer to the contour line formed by the outer contour of the earclip-type earphone 1 on the earhook symmetry plane a-a.

[0044] As Figure 2 shown, when the earclip-type earphone 1 is in a natural state, if the sound-emitting part 11 and the abutting part 12 are spaced apart from each other, the inner contour line and the outer contour line of the earclip-type earphone 1 can be defined by the two end points Q1 and B of the shortest connecting line Q1B between the sound-emitting part 11 and the abutting part 12. The two end points Q1 and B divide the entire contour of the earclip-type earphone 1 into two segments, and the curve that is closer to the ear during wearing in the two curves is the inner contour line.

[0045] As Figure 3 shown, when the earclip-type earphone 1 is in a natural state, the sound-emitting part 11 and the abutting part 12 are in contact with each other, and the sound-emitting part 11, the abutting part 12, and the earhook 13 jointly enclose a closed space 10. The inner contour line of the earclip-type earphone 1 may refer to the contour line that encloses the closed space 10. The remaining contour lines of the earclip-type earphone 1 can be understood as the outer contour lines.

[0046] Please refer to Figure 2 and Figure 4 , Figure 4 is Figure 1 another schematic diagram of the earclip-type earphone shown in the worn state. If the first distance O1 is too small, it will cause the inner contour of the earclip-type earphone 1 to contact the helix E17, which is likely to cause extrusion of the helix E17 and result in poor wearing comfort. If the first distance O1 is too large, it will increase the overall size of the earclip-type earphone 1, resulting in an increase in the overall mass of the earclip-type earphone 1 and a shift in the center of gravity, and the wearing stability will become poor.

[0047] By setting the first distance O1 to be 4 - 9 mm, the inner contour of the earclip-type earphone 1 can bypass the helix E17 as much as possible, avoiding squeezing the helix E17, and at the same time, the overall size of the earclip-type earphone 1 can be controlled within a certain range, which is beneficial to improving the wearing comfort and stability of the earclip-type earphone 1.

[0048] As Figure 2 and Figure 3 shown, in some embodiments, when the earclip-type earphone 1 is in the natural state, on the second side of the reference perpendicular line L2, there is a fifth reference point E on the inner contour line of the earclip-type earphone 1 that is farthest from the reference perpendicular line L2. The distance between the fifth reference point E and the reference perpendicular line L2 is denoted as the second distance O2, and 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 Figure 2 and Figure 4 together. If the second distance O2 is too small, it will cause the inner contour of the earclip-type earphone 1 to contact the antihelix E15, easily squeezing the antihelix E15 and resulting in poor wearing comfort; if the second distance O2 is too large, it will increase the overall size of the earclip-type earphone 1, resulting in an increase in the overall mass of the earclip-type earphone 1 and poor wearing stability.

[0050] By setting the second distance O2 to be 7 - 13 mm, the inner contour of the earclip-type earphone 1 can bypass the antihelix E15 as much as possible, avoiding squeezing the antihelix E15, and at the same time, the overall size of the earclip-type earphone 1 can be controlled within a certain range, which is beneficial to improving the wearing comfort and stability of the earclip-type earphone 1.

[0051] As Figure 2 and Figure 3 shown, in some embodiments, when the earclip-type earphone 1 is in the natural state, on the earhook symmetry plane a - a, the arc-chord ratio of the inner contour line of the earclip-type 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 earclip-type 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] In this application, by setting the first distance O1 to be 4 - 9 mm, the second distance O2 to be 7 - 13 mm, and further setting the arc - chord ratio of the inner contour line of the ear - clip type earphone 1 between the first reference point A and the fourth reference point D to be 1.08 - 1.20, and the arc - chord ratio of the inner contour line of the ear - clip type earphone 1 between the first reference point A and the fifth reference point E to be 1.01 - 1.06, it can better adapt to the shape of the ear, avoid the antihelix E17 and the antihelix E15, which is beneficial to improving the wearing comfort.

[0053] As Figure 2 and Figure 3 shown, in some embodiments, when the ear - clip type earphone 1 is in the natural state, on the ear - hook symmetry plane a - a, there is a sixth reference point F closest to the first reference point A on the contour line of the abutting part 12, and the length of the connecting line AF between the first reference point A and the sixth reference point F is 6 - 10 mm. For example, the length of the connecting line AF can be 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm.

[0054] If the length of the connecting line AF is too small, it will cause the inner contour of the ear - hook 13 to contact the edge 1071 of the antihelix E17 and / or the abutting part 12 to contact the rear side 1072 of the antihelix E17 during the wearing state, which is likely to cause extrusion to the antihelix; if the length of the connecting line AF is too large, it will increase the overall size of the ear - clip type earphone 1, resulting in an increase in the overall mass of the ear - clip type earphone 1 and a shift in the center of gravity, and the wearing stability becomes poor.

[0055] In this application, by setting the length of the connecting line AF to be 6 - 10 mm, the inner contour of the ear - hook 13 can bypass the antihelix E17 as much as possible, avoiding extrusion to the antihelix E17. At the same time, the overall size of the ear - clip type earphone 1 can be controlled within a certain range, which is beneficial to improving the wearing comfort and wearing stability of the ear - clip type earphone 1.

[0056] As Figure 2 shown, in some embodiments, when the ear - clip type earphone 1 is in the natural state, on the ear - hook symmetry plane a - a, the arc - chord ratio of the inner contour line of the ear - clip type 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 type earphone 1 between the first reference point A and the sixth reference point F is too small, it will cause the inner contour of the ear - clip type earphone 1 to contact the antihelix E17, which is likely to cause extrusion to the antihelix E17 and result in poor wearing comfort; if the arc - chord ratio is too large, it will increase the overall size of the ear - clip type earphone 1, resulting in an increase in the overall mass of the ear - clip type earphone 1 and poor wearing stability.

[0058] By setting the arc chord ratio of the inner contour line of the earclip-type 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 earclip-type earphone 1 can better bypass the helix E17, avoiding squeezing the helix E17, and at the same time, the overall size of the earclip-type earphone 1 can be controlled within a certain range, which is beneficial to improving the wearing comfort and wearing stability of the earclip-type earphone 1.

[0059] As Figure 2 and Figure 3 shown, in some embodiments, the earhook 13 includes a support rib 132 and a flexible body 133 that wraps 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 that are oppositely arranged. The first end 1321 of the support rib 132 is connected to the sound generating part 11, and the second end 1322 of the support rib 132 is connected to the abutting part 12. At this time, the position where the first end 1321 of the support rib 132 is located can be understood as the boundary between the earhook 13 and the sound generating part 11, and the position where the second end 1322 of the support rib 132 is located can be understood as the boundary between the earhook 13 and the abutting part 12. That is to say, it can be understood that each section of the earhook 13 includes a support rib 132 and a flexible body 133 that wraps the support rib 132, so as to determine the boundary between the earhook 13 and the sound generating part 11 or the abutting part 12.

[0060] In some embodiments, the earhook 13 may not include the support rib 132 and the flexible body 133 at the same time, but also has a certain elasticity. For example, the sound generating part 11 includes a plastic shell with a certain strength to protect the components arranged therein, and the earhook 13 has elasticity and can deform to provide a clamping force to ensure stability in the wearing state. At this time, the part that can undergo elastic deformation can be understood as the earhook 13, and the part that cannot undergo elastic deformation can be understood as the sound generating part 11 or the abutting part 12. That is to say, it can be understood that each section of the earhook 13 has elasticity, so as to determine the boundary between the earhook 13 and the sound generating part 11 or the abutting part 12.

[0061] As Figure 5 shown, Figure 5 is a three-dimensional schematic diagram of another embodiment of the earclip-type earphone provided by the present application in the natural state. In some embodiments, the earhook 13 and the sound generating part 11 are provided in a two-piece manner, and there is a first parting line 14 at the assembly place between the two. At this time, the position where the first parting line 14 is located can be understood as the boundary between the earhook 13 and the sound generating part 11.

[0062] In some embodiments, the earhook 13 and the abutting part 12 are provided in a two-piece manner, and there is a second parting line at the assembly place between the two. At this time, the position where the second parting line is located can be understood as the boundary between the earhook 13 and the abutting part 12.

[0063] As Figure 2 and Figure 3 shown, on the outer contour line of the earclip-type earphone 1, there is a seventh reference point G that is farthest from the reference tangent line L1, and the seventh reference point G can be located on the earhook 13. In the solution of the present application, by setting the seventh reference point G on the earhook 13, it is beneficial to control the overall size of the earclip-type earphone 1, thereby improving the wearing stability.

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

[0065] In the solution of the present application, by setting the included angle between the connecting line L3 of the opposite ends of the earhook 13 and the reference tangent line L1 to be less than or equal to 45°, the inner contour of the earhook 13 can be adapted to the shape of the ear, further improving the wearing comfort.

[0066] In the above description of this specification, unless otherwise clearly specified and limited, terms such as "fixed", "installed", "connected" or "coupled" should be understood in a broad sense. For example, for the term "connected", it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components or the interaction relationship between two components. Therefore, unless otherwise clearly limited in this specification, those skilled in the art can understand the specific meaning of the above terms in the present invention according to specific circumstances.

[0067] Based on the above description in this specification, those skilled in the art can also understand the following terms used, such as "upper", "lower", "front", "rear", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "center", "longitudinal", "transverse", "clockwise" or "counterclockwise", etc. The terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operate in the specific orientation. Therefore, the above terms of orientation or positional relationship cannot be understood or interpreted as a limitation to the solution of the present invention. In addition, the terms "first" or "second" etc. used in this specification to refer to numbers or ordinals are only for descriptive purposes and cannot be understood as explicitly or implicitly indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this specification, "a plurality" means at least two, such as two, three or more, etc., unless otherwise specifically and clearly defined.
