Description

TECHNICAL FIELD

[0001] The present application relates to the field of earphone structure, in particular to an external earphone. BACKGROUND

[0002] The external earphone, also known as air conduction earphone, is a newly emerged earphone type. The sound outlet of the external earphone is far away from the ear canal, and does not form compression on the auricle. Long-time wearing will not cause the discomfort such as ear swelling and ear compression caused by the in-ear earphone. Moreover, the user can also take into account other sounds from the outside world while listening to the earphone, which is relatively safer in some application scenarios.

[0003] Some external earphones are usually made into C-shaped structure, and the middle of the C-shaped structure is made of elastic material. The elastic deformation of the elastic material realizes the switching between wearing the earphone and taking off the earphone. In the wearing state, the two ends of the C-shaped structure of the earphone clamp the ear from the inner side and the outer side of the ear respectively, so as to make the earphone stably worn on the ear of the user and prevent the earphone from falling off. The clamping force of this type of clamping external earphone on the ear for a long time will cause pain in the ear. SUMMARY

[0047] For better understanding the structure of the external earphone of the present application, and the wearing state of the external earphone on the ear, see Figure 1 、 Figure 2 and Figure 3 In one embodiment, an external earphone comprises a sound producing portion 10, a connecting portion 20, a holding portion 30, and a speaker (not shown in the figure). The connecting portion 20 is in the shape of a bridge, one end of which is connected to the sound producing portion 10, and the other end of which is connected to the holding portion 30.

[0048] The sound producing portion 10 comprises a circular ring flat bottom surface 103 and a first circular arc curved side surface connected to the circular ring flat bottom surface 103. The space enclosed by the circular ring flat bottom surface 103 and the first circular arc curved side surface is used to accommodate the speaker, and the middle part of the circular ring flat bottom surface 103 forms the sound outlet channel of the speaker. The speaker can comprise a conductive coil, a diaphragm, and a permanent magnet, the conductive coil is configured to receive an electric current for generating a moving magnetic field, which interacts with the magnetic field emitted by the permanent magnet, thereby causing the diaphragm to vibrate and generate audio waves, which are output through the sound outlet channel. The circular ring flat bottom surface 103 is almost perpendicular to the vibration direction of the diaphragm. In one embodiment, the circular ring flat bottom surface 103 is in the shape of a flat ring; its circular ring width can be reduced to the point that the circular ring flat bottom surface 103 is close to a circle. As shown in Figure 2 In one embodiment, the channel opening of the sound outlet channel is covered with a mesh cover plate 104, which is connected to the inner ring wall of the circular ring flat bottom surface 103.

[0049] The connecting portion 20 comprises an inner arched surface 201 facing the sound producing portion 10 and the holding portion 30, and an outer convex surface 202 opposite to the inner arched surface.

[0050] The first circular arc curved side surface of the sound producing portion 10 comprises a first inner side surface 101 close to the holding portion 30, and a first outer side surface 102 opposite to the first inner side surface 101.

[0051] The holding portion 30 comprises a circular arc curved bottom surface 303 and a second circular arc curved side surface connected to the circular arc curved bottom surface 303, the second circular arc curved side surface comprises a second inner side surface 301 close to the sound producing portion 10, and a second outer side surface 302 opposite to the second inner side surface 301.

[0052] The outer convex surface 202 of the connecting portion 20 is connected to the first outer side surface 102 to form a first convex surface; the inner arched surface 201 of the connecting portion 20 is connected to the first inner side surface 101 to form a first notch 40; the outer convex surface 202 of the connecting portion 20 is connected to the second outer side surface 302 of the holding portion 30 to form a second convex surface, and the inner arched surface 201 of the connecting portion 20 is connected to the second inner side surface 301 of the holding portion 30 to form a second notch 50.

[0053] The opening degree and depth of the first notch 40 are suitable for the first inner side surface 101 of the sound production part 10 to abut against the antihelix or the inner side of the antitragus; the opening degree and depth of the second notch 50 are greater than those of the first notch 40, so that the second notch 50 can bypass the antihelix or the antitragus and extend to the back of the ear, and at least in one wearing state, the second inner side surface 301 of the holding part 30 abuts against the back of the ear.

[0054] In the embodiment, the sound production part 10 of the external earphone is used to be placed in the space near the antihelix of the cymba or the space near the scaphal notch or the antihelix of the ear cavity, and is movable in the range of the antihelix or the antitragus, and the holding part 30 is used to be placed between the back of the ear and the head of the user, so as to allow the sound production part and the holding part to be stably worn on the ear of the user.

[0055] In the embodiment, the sound production part 10 and the connecting part 20 of the external earphone form the first notch 40, the opening degree and depth of the first notch 40 are suitable for the sound production part 10 to abut against the antihelix or the inner side of the antitragus, so as to hook the antihelix or the antitragus to generate a force against gravity and the external turning of the earphone, the holding part 30 and the connecting part 20 form the second notch 50, the opening degree and depth of the second notch 50 are greater than those of the first notch 40, so that the second notch 50 can bypass the antihelix or the antitragus and extend to the back of the ear, so that the second notch 50 does not generate a clamping force on the antihelix or the antitragus, and does not easily cause pain even if it is worn for a long time; and at least in one wearing state, the holding part 30 can abut against the back of the ear, when the user wears the earphone to run or do other sports, the earphone can bear forces in all directions caused by the body movement, the second inner side surface of the holding part 30 abuts against the back of the ear, which can effectively prevent the earphone from falling off from the wearing state. In the embodiment, the external earphone, the bridge connecting part 20, and the first notch 40 and the hook-shaped structure formed by the connecting part 20 and the sound production part 10 make the sound production part 10 hook the antihelix or the antitragus at least in one wearing state, and the second notch 50 and the hook-shaped structure formed by the connecting part 20 and the holding part 30 make the force of the external earphone turning downward and outward of the ear cause the holding part 30 to form an abutting force against the back of the ear, so that the external earphone is stably worn on the ear and is not easy to fall off.

[0056] Referring to Figure 4 , Figure 5 and Figure 6The wearing angle of the external earphone of the present application on the ear can be changed in a large range. When the sound generating part 10 and the holding part 30 are both moved from the middle part of the ear to the lower part of the ear, the contact position of the sound generating part 10 with the ear is gradually changed from the antihelix to the antitragus, the first inner side surface 101 of the sound generating part 10 gradually widens the abutting position with the ear, and the projection area of the second inner side surface 301 of the holding part 30 on the back of the ear also gradually increases. When the earphone is impacted by the force of falling out of the ear during the movement of the user, the second inner side surface 301 of the holding part 30 can effectively abut against the back of the ear of the user, so as to avoid the sound generating part 10 and the holding part 30 from being tilted out and falling off, and to keep the earphone stable. The wearing angle of the earphone of the present application on the ear can be changed in a large range, and can adapt to the wearing habits of different people and different groups of people.

[0057] In one embodiment, the ear and the external earphone are projected on the plane of the circular flat bottom surface 103 in the state of wearing the earphone on the ear. In this plane, the up-and-down direction of the ear is the Y direction, and the vertical direction of the Y direction in this plane is the X direction. The center point of the ear canal opening shape is marked as A, the center point of the sound generating part shape is marked as B, and the center point of the holding part shape is marked as C. The distance between the center point B of the sound generating part shape and the center point A of the ear canal opening shape in the X direction is h1, and h1 is in the range of 10.5 mm-13 mm. The distance between the center point C of the holding part shape and the center point A of the ear canal opening shape in the X direction is h2, and h2 is in the range of 19.5 mm-30.5 mm.

[0058] Referring to Figure 7 , Figure 7 (a)、 Figure 7 (b)、 Figure 7 (c) respectively Figure 4 , Figure 5 , Figure 6 is a bottom view of the earphone wearing state. In one embodiment, the sound generating part 10 and the connecting part 20 are both located on the same side of the circular flat bottom surface 103, and the circular arc type curved bottom surface 303 of the holding part 30 protrudes to the other side of the circular flat bottom surface 103. At least in one wearing state, the circular flat bottom surface 103 faces the concha cavity, and the circular arc type curved bottom surface 303 of the holding part 30 can abut against the head position on the back of the ear, as shown in Figure 7 (c). In this wearing state, the sound generating part 10 of the external earphone hooks the inner side of the antitragus, the holding part 30 is placed between the back of the ear and the head, the second inner side surface 301 of the holding part 30 abuts against the back of the ear lobe, the circular arc type curved bottom surface 303 of the holding part 30 abuts against the head position on the back of the ear, and the earphone is stable and not easy to fall off. In one embodiment, the sound generating part 10 and the connecting part 20 are both located on the same side of the circular flat bottom surface 103, and the length of the circular arc type curved bottom surface 303 of the holding part 30 protruding to the other side of the circular flat bottom surface 103 is marked as d5 (as shown in Figure 8The range of d5 can be 6-7 mm.

[0059] Referring to Figure 8 , Figure 9 and Figure 10 In one embodiment, the plane on which the circular flat bottom surface 103 is located is a horizontal plane, the plane perpendicular to the circular flat bottom surface 103 and capable of intercepting the farthest distance between the first outer side surface 102 of the sound production part 10 and the second outer side surface 302 of the holding part 30 in the direction parallel to the horizontal plane is a coronal plane, and the plane perpendicular to the horizontal plane and the coronal plane is a sagittal plane.

[0060] The plane parallel to the sagittal plane and tangent to the profile of the first notch 40 in the coronal plane is a first tangent plane, and the point at which the first tangent plane is tangent to the profile of the first notch 40 in the coronal plane is O1. The distance from the point O1 to the circular flat bottom surface 103 is marked as d1, and the range of d1 can be 6-11 mm in one embodiment. The plane parallel to the sagittal plane and tangent to the profile of the first inner side surface 101 of the sound production part 10 in the coronal plane is a second tangent plane, and the distance from the point O1 to the second tangent plane is marked as L1. In one embodiment, the range of L1 can be 4-8 mm. The plane parallel to the sagittal plane and having a distance of L1 / 2 from the point O1 is a third tangent plane, the intersection of the third tangent plane with the first inner side surface of the sound production part 10 in the coronal plane is P, and the intersection of the third tangent plane with the inner arched surface 201 of the connecting part 20 in the coronal plane is Q. In one embodiment, the range of the angle ∠PO1Q can be 72°-76°.

[0061] In the over-ear earphone in the embodiment, the range of the angle ∠PO1Q is related to the opening degree of the first notch 40, the distance from the point O1 to the circular flat bottom surface 103 is related to the thickness of the sound production part 10, and the distance from the point O1 to the second tangent plane is related to the length of the first inner side surface 101 extending from the bottom of the first notch 40 (i.e., the point O1) to the vicinity of the holding part 30. These three factors make the variation trend of the first inner side surface 101 of the sound production part 10 adaptable to the space on the antitragus and under (or on the inner side of) the antihelix, enabling the space to be fully utilized, and enabling the part of the first inner side surface 101 of the sound production part 10 capable of contacting the inner surface of the antitragus or the antihelix to be wide, so that when the sound production part 10 is turned outward, the sound production part 10 can be stopped by the antitragus or the antihelix, thereby being stably worn and avoiding falling off.

[0062] In one embodiment, the distance from the highest point of the connecting portion 20 to the circular flat bottom surface of the sound production portion 10 is marked as d2, and in one embodiment, d2 can range from 16 to 18 mm. In order to make the sound production portion 10 fit into the ear and hook around the antihelix or the antitragus, the connecting portion 20 and the sound production portion 10 need to be connected to form a suitable outer profile surface (i.e., the surface formed by the connection of the outer convex surface 202 of the connecting portion 20, the first outer lateral surface 102 of the sound production portion 10, and the circular flat bottom surface 103 of the sound production portion 10), and in the present embodiment, the distance from the highest point of the connecting portion 20 to the circular flat bottom surface 103 of the sound production portion 10 creates the condition for the suitable outer profile surface. In one embodiment, the maximum inner diameter of the sound production portion 10 parallel to the horizontal plane is marked as r1, and in one embodiment, r1 can range from 12 to 16 mm; the intersection of the plane parallel to the horizontal plane and passing through point O1 with the first convex surface in the coronal plane is E, the midpoint of O1E is F, the two points of the first inner lateral surface 101 and the first outer lateral surface 102 that are farthest apart in the coronal plane are H and G, respectively, the intersection of the vertical line of HG passing through F in the coronal plane with HG is I, and in one embodiment, the length ratio of HI to HG is 0.55 to 0.65. In the present embodiment, the maximum inner diameter of the sound production portion 10 parallel to the horizontal plane and the length ratio of HI to HG make the portion of the sound production portion 10 protruding from the first notch 40 to the holding portion 30 suitable for hooking around the antihelix or the antitragus, and make the sound production portion 10 and the connecting portion 20 form a relatively uniform and smooth curved surface configuration. In one embodiment, the plane parallel to the sagittal plane and tangent to the profile of the second notch 50 in the coronal plane is the fourth tangent plane, and the point at which the fourth tangent plane is tangent to the profile of the second notch 50 in the coronal plane is O2; the plane parallel to the horizontal plane and tangent to the circular arc-shaped curved bottom surface 303 of the holding portion 30 is the fifth tangent plane, and the distance from point O2 to the fifth tangent plane is marked as d3, and in one embodiment, d3 can range from 14 to 16 mm; the plane parallel to the sagittal plane and tangent to the profile of the second inner lateral surface 301 of the holding portion 30 in the coronal plane is the sixth tangent plane, and the distance from point O2 to the sixth tangent plane is marked as L2, and in one embodiment, L2 can range from 8 to 12 mm; the plane parallel to the sagittal plane and at a distance of L2 / 2 from point O2 is the seventh tangent plane, the intersection of the seventh tangent plane with the second inner lateral surface 301 of the holding portion 30 in the coronal plane is R, and the intersection of the seventh tangent plane with the inner arched surface 201 of the connecting portion 20 in the coronal plane is D, and in one embodiment, the angle of ∠RO2D can range from 76° to 80°.

[0063] The angle range of the angle RO2D in the embodiment relates to the opening degree of the second notch 50, the distance from the point O2 to the circular arc type curved bottom surface 303 relates to the thickness of the holding portion 30, and the distance from the point O2 to the sixth section relates to the length of the second inner side surface 301 extending from the bottom of the second notch 50 (i.e. the point O2) to the sound generating portion 10. These three factors make the change trend of the second inner side surface 301 of the holding portion 30 adapt to the space between the back of the ear and the head, and the part of the second inner side surface 301 that can contact the back of the ear is wider. When the user moves, the outwardly folded earphone is resisted by the back of the ear, thereby stably wearing and avoiding falling off.

[0064] In one embodiment, the distance from the highest point of the connecting portion 20 in the coronal plane to the fifth section is marked as d4, and the range of d4 can be 22-24 mm. In the embodiment, the distance d4 from the highest point of the connecting portion 20 in the coronal plane to the fifth section is protruded from the distance d2 from the highest point of the connecting portion 20 in the coronal plane to the circular ring flat bottom surface of the sound generating portion 10, and the suitable length makes the circular ring flat bottom surface 103 face the concha cavity at least in one wearing state, and the circular arc type curved bottom surface 303 of the holding portion 30 can abut against the head position of the back of the ear. Figure 7 (c) shows the wearing state, the sound generating portion 10 of the outwardly folded earphone hooks the inner side of the antitragus, the holding portion 30 is placed between the back of the ear and the head, the second inner side surface 301 of the holding portion 30 abuts against the back of the ear lobe, the holding portion 30 and the circular arc type curved bottom surface 303 abut against the head position of the back of the ear, and the earphone is stable and not easy to fall off.

[0065] In one embodiment, the maximum inner diameter of the holding portion 30 parallel to the horizontal plane is marked as r2, and the range of r2 can be 15-17 mm; the intersection of the plane parallel to the horizontal plane and passing through the point O2 and the second convex surface in the coronal plane is J, the midpoint of O2J is K, the two points of the second inner side surface 301 and the second outer side surface 302 farthest in the horizontal direction in the coronal plane are M and L respectively, and the intersection of the vertical line of ML passing through the point K in the coronal plane and ML is N. In one embodiment, the length ratio of MN to ML is 0.65-0.85. In the embodiment, the maximum inner diameter of the holding portion 30 parallel to the horizontal plane and the length ratio of MN to ML make the part of the holding portion 30 protruding from the second notch 50 to the sound generating portion 10 be able to abut against the back of the ear. When the user wears the earphone and runs, the earphone can bear forces in all directions caused by body movement, the second inner side surface 301 of the holding portion 30 abuts against the back of the ear, which can effectively prevent the earphone from falling off from the wearing state, and make the connecting portion 20 and the holding portion 30 form a relatively uniform and smooth curved surface structure.

[0066] In one embodiment, the distance between the second cut surface and the sixth cut surface is 1.8 to 5.8 mm. In this embodiment, the outer earphone has a larger distance between the sound generating part 10 and the holding part 30 than a conventional earphone, and does not need to rely on the elastic force of the connecting part to bring the sound generating part and the holding part together to hold the inner and outer sides of the ear to form stable wearing, but mainly relies on the hook-shaped structure formed by the connecting part and the sound generating part and the holding part respectively to make the earphone wear stable and comfortable.

[0067] In one embodiment, the farthest distance between the first outer side surface of the sound generating part 10 and the second outer side surface of the holding part 30 in the horizontal direction of the coronal plane is marked as L3, and the range of L3 can be 34-38.8 mm. In this embodiment, the outer earphone has a larger distance between the sound generating part 10 and the holding part 30 than a conventional earphone, and can leave a larger space for the first inner side surface 101 of the sound generating part 10 to protrude towards the holding part 30, and also can leave a larger space for the second inner side surface 301 of the holding part 30 to protrude towards the sound generating part 10, which provides the possibility of a wider contact surface between the first inner side surface 101 of the sound generating part 10 and the inner surface of the antitragus and antihelix, and the possibility of a wider contact surface between the second inner side surface 301 of the holding part 30 and the back of the ear, so that the earphone wears stable and comfortable.

[0068] Referring to Figure 11 In one embodiment, the sound generating part 10 further includes an air bag 105 inside the first inner side surface 101 and inside the first outer side surface 103. The air bag 105 inside the sound generating part 10 can buffer the pressure caused by the contact between the sound generating part 10 and the ear.

[0069] In one embodiment, the sound generating part 10 and the connecting part 30 are made of silicone injection molding. The silicone material of the sound generating part 10 and the connecting part 30 can make the ear have a softer contact feeling, and long-term wearing will not easily cause pain. In one embodiment, the connecting part 30 includes a memory titanium wire or other elastic metal material inside. The use of memory titanium wire or other elastic metal material inside the connecting part 30 makes the connecting part 30 have good elasticity, and the user can wear or take off the earphone more conveniently and comfortably.
