Description

Technical Field

[0001] The utility model relates to the technical field of electronic devices, and particularly relates to an earclip-type earphone. Background Art

[0002] In the field of personal audio devices, earclip-type earphones, as a new type of wearable device, are gradually gaining wide attention. Such earphones break the wearing methods of traditional in-ear or over-ear earphones that need to be inserted into the ear canal or surround the head, and provide a more convenient and comfortable music-playing solution. Without inserting the earphones into the ear canal, users can more conveniently perceive the surrounding environment while enjoying music, which significantly improves the safety and convenience of use.

[0003] For traditional earphones, whether in-ear or over-ear, long-term wearing often causes discomfort to users. In contrast, earclip-type earphones adopt a unique earclip wearing method, and reduce the direct pressure on the ears through a special clamping structure, making the wearing more light and comfortable. Moreover, during sports or daily activities, the earphones can be more firmly fixed on the ears, reducing the risk of the earphones falling off, and becoming an ideal choice for users who are keen on outdoor sports, fitness or daily commuting.

[0004] In the overall structure of earclip-type earphones, it is generally divided into three main components: a sound-emitting part, a battery part, and a connecting arm. The sound-emitting part and the battery part are connected by the connecting arm, and the connecting arm provides a clamping force so that the sound-emitting part and the battery part can be clamped and attached to the wearer's auricle. However, at present, the connecting arms of earclip-type earphones on the market often adopt a symmetric U-shaped or C-shaped design on both sides, that is, the bending angles connecting the sound-emitting part and the battery part are equal. Although such a setting can clamp the human ear, the human auricle actually has a physiological bending trend. When wearing with the above symmetric connecting arm, it is difficult to balance the clamping requirements on the back side and the front side of the helix. When the connecting arm fits the posterior surface of the helix in a corner area, the other corner area will abut against the side of the helix, squeezing or even winding the side of the helix, which will significantly affect the wearing comfort of users after long-term wearing. Summary of the Utility Model

[0005] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide an earclip-type earphone, which has a wide design applicability and can meet the clamping and wearing requirements of various different ear shapes.

[0006] To achieve the above object, the technical solution of the present utility model is: an earclip-type earphone, comprising: a sound generating part, a functional part and a connecting structure, wherein both ends of the connecting structure are respectively connected to the sound generating part and the functional part; in the wearing state, the sound generating part abuts against the concha cavity on the front side of the ear, the sound outlet hole of the sound generating part faces the external auditory canal, the functional part abuts against the back side of the ear, the connecting structure undergoes elastic deformation, and applies an elastic clamping force to the auricle located between the sound generating part and the functional part, and the elastic clamping force is perpendicular to the tangent plane of the functional part contacting the back side of the ear and forms an angle with the vertical plane of the human body; in the horizontal plane projection in the wearing state, a center line is made with the center of the distance between the sound generating part and the functional part, and the center line divides the connecting structure into two parts. The curvature of the connecting structure located on one side of the center line and close to the sound generating part is smaller than the curvature of the connecting structure located on the other side of the center line and close to the functional part.

[0007] It can be understood that the functional part is electrically connected to the sound generating part and is used for supplying power to and controlling the sound generating part. When the user wears the earphone, the sound generating part abuts against the concha cavity on the front side of the ear, the sound outlet hole of the sound generating part faces the external auditory canal, the functional part abuts against the back side of the ear, both ends of the arc-shaped connecting structure are respectively connected to the sound generating part and the functional part, and the connecting structure has elasticity and undergoes elastic deformation to clamp the auricle in the wearing state. The elastic clamping force is perpendicular to the tangent plane of the functional part contacting the back side of the ear and forms an angle with the vertical plane of the human body, so as to realize the clamping and fixing of the earphone at the user's ear. The overall appearance shows that the sound generating part, the connecting structure and the functional part jointly form a clamping space for clamping the auricle. Considering comprehensively that the earphone is worn on the human ear with a physiological curvature and combined with the difference in the size of the human ear, the shape of the earclip-type earphone is designed, and the curvature of the connecting structure is designed. The curvature close to the sound generating part is smaller than the curvature close to the functional part, that is, the part of the connecting structure close to the sound generating part is relatively flat, while the part close to the functional part is more curved, that is, the connecting structure is arranged as an asymmetric arc-shaped structure. This results in that in the wearing state, the functional part fits more closely to the back of the ear, and the clamping space formed by the functional part and the connecting structure is small, while the clamping space formed by the sound generating part and the connecting structure is large, reducing the contact, extrusion and even winding of the connecting structure with the side of the helix, and being compatible with the clamping and wearing of the earclip-type earphone for various ear shapes and various ear sizes, improving the comfort of wearing the earphone.

[0008] In a possible implementation manner, in the worn state, the earphone has a first projection on the horizontal plane; the first projection includes an inner contour; two tangent points where the two farthest ends of the connection structure are tangent to the tangent line on the inner contour, the tangent point closer to the projection of the sound generating part is the first contact point, and the tangent point closer to the projection of the functional part is the second contact point; the ratio range of the distance between the first contact point and the line segment where the highest point of the inner contour radian of the connection structure is located to the distance between the second contact point and the highest point of the inner contour radian of the connection structure is 1.2 - 1.5:1.

[0009] In a possible implementation manner, the distance range between the first contact point and the second contact point is 12.0 mm - 16.0 mm; the distance range between the highest point of the inner contour radian and the lowest point corresponding to the connection structure on the inner contour is 8.5 mm - 9.0 mm.

[0010] Further limit the size of the connection structure. On the inner contour, when the maximum horizontal distance of the inner contour remains within 12.0 mm to 16.0 mm, and the distance between the highest point and the lowest point in the vertical direction satisfies 8.5 mm to 9.0 mm, when the inner contour size of the first projection is within the multiple rectangles formed by the horizontal length and the vertical length, the ear-clip space formed with the sound generating part and the functional part has an appropriate wearing clamping force on the human ear, and at the same time can meet the connection strength between the two ends of the connection structure and the sound generating part and the functional part. The overall proportion is appropriate and aesthetic, and no additional raw materials are required during the production process.

[0011] In a possible implementation manner, taking the straight line where the first contact point and the highest point of the inner contour radian of the connection structure are located as the first reference line, and taking the straight line where the second contact point and the highest point of the inner contour radian of the connection structure are located as the second reference line, the included angle formed by the first reference line and the second reference line is the clamping angle. In the worn state, the clamping angle range of the clamping angle is 113° - 118°.

[0012] In a possible implementation manner, taking the perpendicular line where the highest point of the inner contour radian of the connection structure is located as the third reference line; the included angle formed by the first reference line and the third reference line is greater than the included angle formed by the second reference line and the third reference line.

[0013] In a possible implementation, the axial cross-section of the connection structure is elliptical. The connection structure includes a first arc portion and a second arc portion connected in sequence. The free end of the first arc portion is fixedly connected to the sound generating portion, and the free end of the second arc portion is fixedly connected to the functional portion. The connection between the first arc portion and the second arc portion is the location where the axial cross-sectional area of the connection structure is the smallest, and the area of the connection structure gradually increases from this connection point towards both ends. Further, when comparing the axial cross-sectional area of the connection structure where the first contact point is located with the axial cross-sectional area of the connection structure where the second contact point is located, the axial cross-sectional area of the connection structure where the first contact point is located is smaller than the axial cross-sectional area of the connection structure where the second contact point is located.

[0014] In a possible implementation, taking the axial cross-section where the connection point is located as the longitudinal projection plane, the first arc portion has a second projection on the longitudinal projection plane, and the second arc portion has a third projection on the longitudinal projection plane. The bottom widths of the second projection and the third projection are of equal length, and the longitudinal length of the second projection is longer than the longitudinal length of the third projection.

[0015] In a possible implementation, the ratio relationship between the longitudinal length of the second projection and the longitudinal length of the third projection satisfies 1.40 - 1.45:1.

[0016] In a possible implementation, the sound generating portion is provided with a sound outlet hole. In the worn state, the sound outlet hole is clamped in the concha cavity and is aligned with the ear canal.

[0017] In a possible implementation, the cross-sectional area of the sound generating portion gradually decreases along the direction towards the ear canal.

[0018] In a possible implementation, the angle between the orientation of the sound generating portion and the longitudinal axis direction of the functional portion is 55 - 60°.

[0019] In a possible implementation, the distance between the sound generating portion and the functional portion is 2.5 mm - 4 mm.

[0020] In a possible implementation, the side surface of the functional portion close to the sound generating portion presents a concave surface.

[0021] In a possible implementation, the functional portion is convexly provided with a detection portion for heart rate monitoring towards the sound generating portion.

[0022] In a possible implementation, the thickness of the detection portion is 0.5 mm - 0.6 mm.

[0023] In a possible implementation, the connecting portion includes a first arm beam and a second arm beam arranged side by side.

[0024] In a possible implementation, along the direction from the sound generating part to the functional part, the first arm beam and the second arm beam gradually approach each other.

[0025] It can be understood that by arranging the connecting structure as the first arm beam and the second arm beam in parallel, an ear clip structure with a double arm beam is formed. The double arm beam can achieve mutual compensation of the clamping force in the wearing state, achieving better elastic deformation ability. Even in the case of long-term or excessive opening during use, it can maintain relatively stable clamping performance, which helps to improve the wearing stability.

[0026] The beneficial effect of the present utility model is that: compared with the prior art, in the clamping and wearing state of the ear clip type earphone of the present utility model, the functional part fits against the back of the ear and the sound generating part faces the external auditory canal. Since the curvature of the connecting structure located on one side of the midline and close to the sound generating part is smaller than the curvature of the connecting structure located on the other side of the midline and close to the functional part, the ear clamping space formed with the auricle is large, which can reduce the contact, extrusion or even winding between the internal contour of the earphone and the side edge of the helix, meeting the clamping and wearing requirements of the ear clip type earphone for various ear shapes and sizes, and improving the comfort of wearing the earphone.

[0057] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution 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. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0058] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0059] Combination Figure 1 The user's ear 100 may include an external auditory canal 101, a cavum conchae 102, a cymba conchae 103, a triangular fossa 104, an antihelix 105, a scaphoid 106, an auricle 107, and an antitragus 108. Although the external auditory canal 101 has a certain depth and extends to the eardrum, for the sake of convenience of description, and in combination with Figure 1 In the present application, unless otherwise specified, the external auditory canal 101 specifically refers to its entrance away from the tympanic membrane (i.e., the ear hole). Furthermore, the concha cavity 102, the hymena conchae 103, the triangular fossa 104 and other physiological parts have a certain volume and depth; and the concha cavity 102 is directly connected to the external auditory canal 101, which can be simply regarded as the aforementioned ear hole being located at the bottom of the concha cavity 102.

[0060] Further, there is also a tragus 109 around the outer ear canal 101 of the ear part 100. Compared with parts such as the concha 102, the cymba conchae 103, and the triangular fossa 104, they have a certain depth and volume in three-dimensional space, that is, these parts are respectively recessed towards the rear side of the ear along the direction close to the user's head, while the tragus 109 protrudes towards the front side of the ear along the direction away from the user's head. Herein, the "front side of the ear" described in this application is a concept relative to the "rear side of the ear". The former refers to the side of the ear away from the head, for example Figure 1 , and the latter refers to the side of the ear towards the head, and both are for the user's ear.

[0061] Further, different users may have individual differences, resulting in different sizes such as shapes and sizes of the ears. For the convenience of description and to reduce (even eliminate) the individual differences of different users, the present utility model uses an ear simulator (model GRAS RA0045) for wearing instructions. Therefore, in this embodiment, descriptions such as "the user wears the earphone", "the earphone is in a worn state", and "in the worn state" may refer to the earphone described in this application being worn on the ear part of the aforementioned simulator. Of course, precisely because different users have individual differences, there may be certain differences when the earphone is worn by different users compared to when the earphone is worn on the ear part of the aforementioned simulator, but such differences should be tolerated.

[0062] Combined with the attached Figure 1 —8 to illustrate the present utility model, the present utility model provides an earphone, which is a clip-on wireless earphone (True Wireless Stereo, TWS) and is clamped and worn on the auricle. The clip-on earphone can reduce the discomfort of the wearer's ear and improve the wearing comfort. In this way, the earphone does not need to go deep into the inner part of the user's ear canal, which can reduce ear canal allergies and injuries. The user can perceive the changes in the surrounding environment at any time and reduce the accident risk.

[0063] It should be noted that a pair of earphones includes two earphones. Since the two earphones of the present utility model do not need to be distinguished between the left ear and the right ear for wearing, any one of the earphones of the present utility model is described in the embodiment.

[0064] As Figure 2 shown, a clip-on earphone includes: a sound generating part 1, a functional part 2, and a connecting structure 3 connecting the sound generating part 1 and the functional part 2.

[0065] Embodiment 1

[0066] The connecting structure 3 is integrally arc-shaped and is composed of a memory wire and a wire inside wrapped by an external TPU material.

[0067] The sound generating part 1 is internally installed with a speaker and an FPC board, and the sound generating part 1 is fixedly connected and inserted with one end of the connecting structure 3.

[0068] The functional part 2 is internally installed with an antenna bracket, a main board PCB, a battery, a MIC flexible board, and a detection FPC. The detection FPC is used for heart rate monitoring and in-ear detection. The other end of the functional part 2 is plug-fixed to the connection structure 3. A magnet and charging pins are arranged on one side of the functional part 2 away from the connection structure 3, and the charging pins protrude from the side surface of the housing of the functional part 2.

[0069] The internal structures of the sound generating part 1, the connection structure 3, and the functional part 2 are not shown in the present utility model.

[0070] The earclip-type earphone uses the elasticity of the connection structure 3 to make the sound generating part 1 and the functional part 2 have a force that makes them approach each other, and is worn on the auricle in a clamping manner. The sound generating part 1 abuts against the concha 102 on the front side of the ear and faces the external auditory canal 101, and the functional part 2 abuts against the back side of the ear. The sound generating part 1 and the functional part 2 are electrically connected through the wire in the earclip, so that the sound generating part 1 emits sound towards the external auditory canal 101;

[0071] Combined with the attached Figure 4 , in the wearing state, the connection structure 3 undergoes elastic deformation and applies an elastic clamping force F to the auricle located between the sound generating part 1 and the functional part 2. The elastic clamping force is perpendicular to the tangent plane (the plane where f1 is located) of the functional part contacting the back side of the ear and forms an angle with the vertical plane of the human body, that is, the sagittal plane (a positioning term in human anatomy: the front-back direction divides the body into left and right parts; the plane that divides the body into two equal left and right parts in the middle is called the sagittal plane, which is represented by the straight line f2 in the figure); in the horizontal plane projection in the wearing state, combined with Figure 5 , a center line m is made with the center of the distance between the sound generating part 1 and the functional part 2. The center line m divides the connection structure 3 into two parts. The curvature of the connection structure 3 on one side of the center line m and close to the sound generating part 1 is smaller than the curvature of the connection structure 3 on the other side of the center line m and close to the functional part 2. Further, the curvature (i.e., the degree of bending) of the connection structure 3 in the part close to the sound generating part 1 is smaller than its curvature in the part close to the functional part 2, that is, the connection structure 3 is an asymmetric arc-shaped structure, which is manifested in that when transitioning from the functional part 2 to the sound generating part 1, its curvature gradually becomes smaller, and the bending degree at the position close to the sound generating part 1 is relatively flatter. Combined with Figure 3 and Figure 4, which makes it so that when worn, in a view looking downward in a direction perpendicular to the body, the ear-clip space 4 formed between the connection structure 3 and the inner side of the outer ear portion of the ear simulator 0 (GRAS RA0045) and the sound-emitting part 1 is larger than the ear-clip space 4 formed between the connection structure 3 and the dorsal side of the auricle portion of the functional part 2 and the ear simulator 0 (GRAS RA0045). From a position with the outer ear close to the head (adhering to the ear) to a position with the outer ear relatively far from the head (flared ear), from a small ear (the antihelix 105 and the scaphoid fossa 106 are relatively narrow) to a large ear (the antihelix 105 and the scaphoid fossa 106 are relatively wide), comfortable clamping can be achieved, reducing the contact between the inner contour of the earphone and the side of the helix 107 and preventing extrusion or even winding of the antihelix 107, meeting the clamping and wearing requirements of ear-clip headphones for various ear shapes and sizes and improving the comfort of earphone wearing.

[0072] In some embodiments, in combination with Figure 5 , in the worn state, the earphone has a first projection on a horizontal plane; the first projection includes an inner contour 30; the two tangent points where the connection structure 3 is tangent to the tangent line segment at the two farthest ends on the inner contour 30, the tangent point closer to the projection of the sound-emitting part 1 is the first contact point A, and the tangent point closer to the projection of the functional part 2 is the second contact point C. Regarding the tangent line segment, the tangent line segment is the tangent of the arc where the two farthest ends of the connection structure 3 are located on the inner contour 30. In the appendix Figure 5 , it is the vertical virtual line segment where point A is located and the virtual line segment where point C is located.

[0073] In combination with Figure 6 , the relationship between the distance AB between the first contact point A and the highest point B of the arc of the inner contour 30 of the connection structure 3 and the distance CB between the second contact point C and the highest point B of the arc of the inner contour 30 of the connection structure 3 satisfies AB / CB being 1.22 - 1.26:1. Starting from the comfort of clamping, the ear-clip earphone is designed. Without affecting the main structures of the sound-emitting part 1 and the functional part 2, when the inner contour 30 of the connection structure 3 satisfies the following relationship, that is, AB / CB is 1.2 - 1.5:1, the clamping comfort of the ear-clip earphone is good, specifically it can be 1.2:1, 1.3:1, 1.4:1, 1.5:1.

[0074] In some embodiments, the distance between the first contact point A and the second contact point C ranges from 12.0 mm to 16.0 mm; meanwhile, the distance between the highest point B of the 30-degree inner contour and the lowest point D of the connection structure 3 corresponding to the 30-degree inner contour ranges from 8.5 to 9.0 mm. That is, when the size of the inner contour 30 of the first projection is within the rectangular frame S defined by AC and BD, the connection structure 3 and the ear-clamping space 4 formed by the sound-generating part 1 and the functional part 2 have an appropriate wearing clamping force on the human ear. In some specific embodiments, the rectangle S where the inner contour 30 is located can be 12.0 mm × 9.0 mm, 13.0 mm × 8.9 mm, 14.0 mm × 8.7 mm, 15.0 mm × 8.93 mm, 16.0 mm × 8.6 mm, 12.0 mm × 8.5 mm, 13.0 mm × 8.6 mm, 14.0 mm × 8.7 mm, 15.0 mm × 8.8 mm, 16.0 mm × 8.9 mm, 16.0 mm × 9.0 mm.

[0075] In some embodiments, the straight line where the first contact point A and the connection structure 3 are located at the highest point B of the 30-degree inner contour is taken as the first reference line, and the straight line where the second contact point C and the connection structure 3 are located at the highest point B of the 30-degree inner contour is taken as the second reference line. The included angle between the first reference line and the second reference line is the clamping angle, that is, the included angle formed by the first contact point A and the second contact point C with the connection structure 3 at the highest point B of the 30-degree inner contour is the clamping angle ∠ABC. In the wearing state, the clamping angle range of the clamping angle ∠ABC is 113° - 118°. Based on a large amount of user data and ergonomic research, when wearing ear-clip headphones, the clamping angle of ∠ABC is designed and controlled between 113° - 118°, which balances the contact area between the headphones and the ears. Without sacrificing stability, it can provide sufficient flexibility to match the thickness of the human ear to adapt to different activities. Even during running, jumping or other strenuous exercises, the headphones are not easy to fall off, and at the same time, the user will not feel discomfort due to being too tight, reducing the wearing discomfort. In some specific embodiments, the clamping angle of the clamping angle ∠ABC can be 113°, 114°, 115°, 116°, 117°, 118°. At this time, the clamping force of the clamping angle on the human ear is moderate, suitable for long-term stable clamping and wearing without causing a sense of compression on the human ear.

[0076] In some embodiments, in combination with Figure 6 , taking the vertical line where the connection structure 3 is located at the highest point of the 30-degree inner contour as the third reference line, that is Figure 6 straight line n; assuming the included angle formed by the line segment AB and the third reference line is γ, and the included angle formed by the line segment BC and the third reference line is β, that is, the relationship between γ and β is γ > β.

[0077] In some embodiments, as Figure 7 shown asFigure 5 The cross-sectional view at A-A in the middle, the axial cross-section A-A of the connecting structure 3 is elliptical. Specifically, the connecting structure 3 as a whole presents a long arc shape with an elliptical cross-section, which on the one hand provides a more gentle and modern appearance, and on the other hand, the elliptical structure usually shows higher strength in terms of anti-bending while maintaining the necessary flexibility.

[0078] In some embodiments, the connecting structure 3 includes a first arc portion 31 and a second arc portion 32 connected in sequence. The free end of the first arc portion 31 is fixedly connected to the sounding portion 1, and the free end of the second arc portion 32 is fixedly connected to the functional portion 2; the connection between the first arc portion 31 and the second arc portion 32 is the place where the axial cross-sectional area of the connecting structure 3 is the smallest, and the area of the connecting structure 3 gradually increases from the connection to both ends. The middle part of the connecting structure 3 is thinner, reducing the use of materials and the weight of the earphone. It gradually becomes thicker along the two ends of the sounding portion 1 and the functional portion 2, providing stronger structural support, enhancing the overall durability and anti-bending ability of the earphone; in terms of wearing, it helps to distribute the weight of the earphone more evenly, making the wearing feel more balanced and reducing the additional pressure caused by uneven weight.

[0079] In some embodiments, the axial cross-sectional area of the connecting structure where the first contact point A is located is smaller than the axial cross-sectional area of the connecting structure where the second contact point C is located. This enables the first arc portion 31 to deform first and the second arc portion 32 to deform later when wearing the earclip-type earphone.

[0080] In some embodiments, in combination Figure 5 - Figure 8 , taking the axial cross-section A-A plane where the connection is located as the longitudinal projection plane, the first arc portion 31 has a second projection on the longitudinal projection plane, and the second arc portion 32 has a third projection on the longitudinal projection plane; the bottom widths of the second projection and the third projection are equal in length, and the longitudinal length b of the second projection is longer than the longitudinal length a of the third projection. When taking the longitudinal projection plane of the axial cross-section at the thinnest part of the connecting arm, the first arc portion 31 and the second arc portion 32 have an overlapping part on this projection plane; both the second projection and the third projection present a vertical long strip shape, with equal-width overlapping at the top and equal-width at the bottom, and since the second projection is longer than the third projection. That is, the first arc portion 31 has a longer length in the longitudinal projection direction. On the one hand, this enables the sounding portion 1 connected to the first arc portion 31 to better penetrate into the external auditory canal 101 and be embedded with the inside of the ear, realizing the wearing stability of the earclip-type earphone. On the other hand, it can prevent the functional portion 2 from touching the mastoid process of the temporal bone (also known as the mastoid part, located at the lower rear of the temporal bone), and can improve the wearing comfort.

[0081] In some embodiments, the ratio of the longitudinal length b of the second projection to the longitudinal length a of the third projection satisfies 1.40 - 1.45:1. In addition to studying the clamping force and the clamping range that conforms to the shape and size of the human ear for the comfort of wearing the earclip-type earphone, the stability during clamping and wearing without shaking with the body are also important factors for the comfort of wearing the earclip-type earphone. Based on a large amount of user data and ergonomic research, there is actually a matching relationship between the lengths of the functional part 2 and the sound generating part 1 in the longitudinal projection plane. After determining the length of the functional part 2, the depth of penetration of the sound generating part 1 will change accordingly. And when the ratio of the longitudinal length of the second projection to the longitudinal length of the third projection satisfies 1.40 - 1.45, the sound generating part 1 is aligned with the external auditory canal 101 and the clamping position of the sound generating part 1 is accurate. The sound generating part 1 is close to the inner wall of the concha 102 of the inner ear, increasing the static friction and improving the wearing stability; furthermore, the sound generating part 1 fits better with the shape of the ear, reducing the pressure on the auricle, thereby enhancing the comfort of long-term wearing. In some specific embodiments, the ratio of b:a can be 1.40, 1.41, 1.42, 1.43, 1.44, 1.45.

[0082] In some embodiments, referring to the attached Figure 9 , the sound generating part 1 is provided with a sound outlet hole 10. In the wearing state, the sound outlet hole 10 is clamped in the concha 102, and the sound outlet hole 10 is aligned with the external auditory canal 101. In the wearing state, the sound outlet hole 10 being aligned with the external auditory canal 101 ensures direct transmission of the audio to the ear, reducing the loss during the sound propagation process, improving the clarity and volume of the sound, and providing a richer audio experience.

[0083] In some embodiments, the cross-sectional area of the sound generating part 1 gradually decreases along the direction towards the external auditory canal 101. In order to adapt to the shape of the human ear and optimize the sound propagation direction of the sound generating part 1, the sound generating part 1 is designed to gradually decrease along the direction towards the external auditory canal 101, adapting to the natural shape of the concha 102, increasing the contact area with the inside of the concha 102, reducing the pressure on the ear, and increasing the wearing comfort, especially suitable for long-term wearing.

[0084] In some embodiments, the included angle α between the orientation of the sound - generating part 1 and the longitudinal axis direction of the functional part 2 is 55 - 60°. The design of the included angle between the orientation of the sound - generating part 1 and the functional part 2 is controlled within 55 - 60°. At this time, the sound - emitting hole 10 can naturally and accurately align with the external auditory canal 101. The bottom side of the sound - generating part 1 contacts the inner side of the concha 102, and the upper side of the sound - generating part 1 contacts the tragus, so that the audio signal can enter the external auditory canal 101 more directly, improving the sense of direction and three - dimensionality of the sound. This is also the main reason why the earphones of the present utility model do not need to be distinguished between left and right earphones for wearing. Moreover, when the user wears the earphones, the position of the sound - generating part 1 can be quickly located without additional adjustment, simplifying the adjustment of the wearing process, improving the wearing speed, and enhancing the convenience of wearing. In some specific embodiments, ∠α can be 55°, 56°, 57°, 58°, 59°, 60°.

[0085] In some embodiments, the distance d between the sound - generating part 1 and the functional part 2 is 2.5 - 4 mm. In the non - wearing state, setting the distance between the sound - generating part 1 and the functional part 2 between 2.5 - 4 mm means that there is a certain spatial interval when the earphones are initially worn. Therefore, when wearing, the clamping pressure of the ear - clip type earphones on the ears is reduced, the wearing comfort is improved, and the earphones are not likely to fall off due to the excessive distance between the sound - generating part 1 and the functional part 2. In some specific embodiments, d can be 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3.0 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4.0 mm.

[0086] In some embodiments, the side surface of the functional part 2 close to the sound - generating part 1 is concave. The concave design of the functional part 2 can better fit the shape of the back of the ear, enabling the whole earphone to be worn on the ear more stably, reducing displacement or slipping during movement or daily activities, reducing the sense of pressure on the ear, and enhancing the comfort of long - term wearing.

[0087] In some embodiments, the functional part 2 is convexly provided with a detection part 21 for heart rate monitoring on the side towards the sound - generating part 1.

[0088] In some embodiments, the thickness of the detection part 21 is 0.5 mm - 0.6 mm.

[0089] It can be understood that by providing the detection unit 21 in the functional unit 2 for detecting the heart rate, the overall functionality of the earphone is improved. Without changing the distance between the sound generating unit 1 and the functional unit 2, designing the thickness of the detection unit 21 to be 0.5 mm - 0.6 mm can ensure good contact between the heart rate monitoring sensor and the skin, improving the accuracy of heart rate monitoring. The thin design of the detection unit 21 helps to maintain the overall lightness of the earphone and improve the wearing comfort.

[0090] Embodiment 2

[0091] See Figure 10 - Figure 11 In this embodiment, similarly, the curvature (i.e., the degree of bending) of the connecting structure 3 in the part close to the sound generating unit 1 is less than the curvature of the part close to the functional unit 2, that is, the connecting structure 3 is an asymmetric arc-shaped structure, which means that when transitioning from the functional unit 2 to the sound generating unit 1, its curvature gradually becomes smaller, and the bending degree at the position close to the sound generating unit 1 is relatively flatter.

[0092] In a specific embodiment, the connecting structure 3 includes a first arm beam 33 and a second arm beam 34 arranged side by side. Along the direction from the sound generating unit 1 to the functional unit 2, the first arm beam 33 and the second arm beam 34 gradually approach each other.

[0093] In a further specific embodiment, the first arm beam 33 is provided with a through hole. A wire is provided inside the first arm beam 33. One end of the wire is electrically connected to the battery provided in the functional unit 2, and the other end is electrically connected to the speaker provided in the sound generating unit 1.

[0094] The sound generating unit 1 is integrally hollow and forms a sound cavity for placing the speaker. The speaker divides the sound cavity into a front sound cavity and a rear sound cavity. The sound outlet hole is provided on the cavity wall of the front sound cavity, and a tuning hole is provided on the cavity wall of the rear sound cavity; an inverted phase tube is provided in the rear sound cavity. The sound inlet end of the inverted phase tube is close to the speaker, and the sound outlet end of the inverted phase tube extends in a direction close to the connecting structure 3 and away from the rear sound cavity. The second arm beam 34 is provided with an inverted phase channel, one end of which communicates with the rear sound cavity, and the other end communicates with the surface of the second arm beam to form an inverted phase sound outlet hole.

[0095] To ensure the performance of the earclip-type earphone of the present invention in actual application, a wearing test is specifically carried out on the earclip-type earphone of Embodiment 1 of the present invention. 30 earclip-type earphones within the parameter range of the present invention are randomly selected and arbitrarily assigned to 30 company employees randomly selected and recorded as sample numbers 1 - 30 (the samples cover different ages, genders, and different departments to obtain representative and extensive test data).

A quantitative scoring table (with a full score of 10 points) is used to score the comfort and firmness.

[0097] Among them, the full scores for comfort and firmness are 10 points.

[0098] Comfort evaluation: Measure the pressure sensation generated when the headphone clamps the auricle and the discomfort level caused by long-term wearing (2 hours).

[0099] Firmness evaluation: Examine the stability of the headphone during various daily activities and sports states, and whether there is a risk of falling off.

[0100] Evaluation of the alignment position of the sound outlet hole 10: Observe whether the sound outlet hole 10 of the headphone is accurately aligned with the opening of the external auditory canal 101.

[0101] Evaluation of the fitting degree with the antitragus: Evaluate the fitting degree of the contact surface between the headphone and the antitragus, and examine its wearing convenience. The following is the wearing information collection form.

[0106] Second, the clip-on headphones of the present utility model can accurately align with the external auditory canal 101 without error, achieving intuitive wearing without the need to distinguish between left and right. Wearing this headphone is fast and simple, and there are very few situations that require adjustment, demonstrating excellent user-friendliness and convenience.

[0107] Third, the test results show that this clip-on headphone can both stably clamp and maintain a moderate pressure, without causing a significant sense of compression on the ears, providing a good wearing experience. During the long-term wearing process, the testers generally did not feel obvious discomfort, demonstrating excellent long-term wearing comfort.
