[0052] like Figures 1 to 14 As shown, in one embodiment of the present application, an earphone is provided, including an earphone head 12, a vital sign detection component 1221, a speaker 30, a microphone 40 and a bracket 50, the earphone head 12 is provided with an installation cavity 13, the speaker 30 and the bracket 50 are both located in the installation cavity 13, the vital sign detection component 1221 is located on the side of the speaker 30, and the microphone 40 is located below the speaker 30; an installation through hole 131 is provided on the inner peripheral wall of the installation cavity 13, the vital sign detection component 1221 is located in the installation through hole 131, and is used to detect the vital sign parameters of the user; the bracket 50 includes a first fixing portion 51, a semi-circle portion 52 and a second fixing portion 53, a fixing protrusion 132 extending along the circumferential direction of the mounting cavity 13 is provided on the inner circumferential wall thereof, two ends of the semi-circle portion 52 are respectively connected with two ends of the fixing protrusion 132, and a first mounting hole 520 is formed therearound, the speaker 30 is mounted in the first mounting hole 520, the first fixing portion 51 is connected to the outer circumferential wall of the semi-circle portion 52, the first fixing portion 51 is pressed against the vital sign detection component 1221, so as to fix the vital sign detection component 1221 in the mounting through hole 131; the second fixing portion 53 is connected to the surface of the semi-circle portion 52 facing the bottom surface of the mounting cavity 13, and the second fixing portion 53 presses the microphone 40 against the bottom surface of the mounting cavity 13.

[0053] Specifically, see Figure 3 and Figure 8 As shown, in the earphone of the embodiment of the present application, the semi-circle portion 52 of the bracket 50 and the fixing protrusion 132 on the earphone head 12 are arranged to form a first mounting hole 520, and the speaker 30 is installed in the first mounting hole 520. In this way, by effectively utilizing the fixing protrusion 132 structure on the inner wall of the earphone head 12, there is no need to set a larger bracket 50, thereby effectively reducing the external dimensions of the earphone. In addition, the first fixing portion 51 and the second fixing portion 53 on the bracket 50 can also be the microphone 40 and the vital sign detection component 1221. In this way, there is no need to set other fixing components, which reduces the installation components in the earphone head 12, and can further reduce the external dimensions of the earphone, thereby improving the wearing comfort of the earphone.

[0054] In this embodiment, the center of the semicircle portion 52 does not coincide with the center of the fixing protrusion 132 , so that the shape of the first mounting hole 520 formed by splicing is compatible with the shape of the speaker 30 , ensuring the stable and reliable installation of the speaker 30 .

[0055] In this embodiment, see Figure 1 , Figure 2 and Figure 3As shown in the figure, the earphone body 10 of the earphone comprises an earphone handle 11 and an earphone head 12 for inserting into the concha cavity, the earphone head 12 is connected to the earphone handle 11, a sound mouth 121 is arranged on the earphone head 12, and an ear cap 1211 for inserting into the ear canal is sleeved on the sound mouth 121; specifically, the earphone head 12 is installed on the side of the earphone handle 11, and the earphone head 12 and the earphone handle 11 are buckled together to form a closed installation cavity 13 for installing components such as a circuit board 60, a speaker 30, and a microphone 40; in addition, the installation cavity 13 is also provided with a first electrical connection sheet 81, the first electrical connection sheet 81 is bent and extended from the power connection end of the microphone 40 along the first fixing portion 51 and the vital sign detection component 1221 to the end surface of the speaker 30 facing away from the bracket 50, and then bent in the reverse direction and extended to the ear The earphone is inside the handle portion 11 and is electrically connected to the circuit board 60 of the earphone handle portion 11, wherein the first electrical connecting piece 81 is clamped with the first fixing portion 51 and the vital sign detection component 1221, and is pressed against the end face of the speaker 30, thereby achieving electrical conduction between the speaker 30, the microphone 40, the vital sign detection component 1221 and the circuit board 60. In addition, the battery 70 in the earphone handle portion 11 is electrically connected to the circuit board 60 through the second electrical connecting piece 82, thereby achieving signal transmission and power transmission between the various components, and realizing intelligent use of the earphone. It should be noted that the first electrical connecting piece 81 is pressed against the end face of the speaker 30, stably fixing the speaker 30 to the first mounting hole 520, and also achieving axial positioning of the bracket 50, so that the earphone is firm and reliable to use.

[0056] In another embodiment of the present application, see Fig. 9 As shown, both end surfaces of the fixing protrusion 132 of the provided earphone are first inclined surfaces 1321, and in the direction of the fixing protrusion 132 toward the semicircle portion 52, the first inclined surface 1321 extends obliquely toward the cavity bottom surface of the installation cavity 13; both end surfaces of the semicircle portion 52 are second inclined surfaces 521, and the first inclined surface 1321 fits with the second inclined surface 521. Specifically, when the first inclined surface 1321 and the second inclined surface 521 fit, the first inclined surface 1321 has an axial upward supporting force on the second inclined surface 521 of the semicircle portion 52, thereby playing an axial positioning role for the bracket 50; in addition, the limiting method of the inclined surfaces fitting each other is adopted, which does not require the use of other fixing components, reduces the number of components inside the earphone, and greatly reduces the external dimensions of the earphone.

[0057] In another embodiment of the present application, see Figure 8 As shown, the outer wall of the semi-circular portion 52 of the earphone is fitted on the inner wall of the mounting cavity 13, and there is no gap between the semi-circular portion 52 and the inner wall of the mounting cavity 13, which can also reduce the outer dimensions of the earphone.

[0058] In another embodiment of the present application, see Fig.10 As shown, the inner circumferential wall of the mounting cavity 13 of the earphone provided is provided with a first limiting protrusion 133, and the surface of the semicircular portion 52 facing the cavity bottom surface of the mounting cavity 13 is pressed against the first limiting protrusion 133. The semicircular portion 52 is pressed against the first limiting protrusion 133, and the semicircular portion 52 cannot move toward the cavity bottom surface of the mounting cavity 13. On the one hand, the axial positioning of the semicircular portion 52 is more stable and reliable; on the other hand, excessive squeezing of the microphone 40 can also be avoided, which may cause damage to the microphone 40. More specifically, the two ends of the first limiting protrusion 133 are respectively connected to the two first inclined surfaces 1321, so that the entire semicircular portion 52 is pressed against the first limiting protrusion 133, and the bracket 50 is fixed more firmly; in addition, the limiting method of the first limiting protrusion 133 is adopted, and this method does not need to adopt other fixing components, reduces the number of components inside the earphone, and greatly reduces the external dimensions of the earphone.

The second limiting protrusions 1322 are inserted into the limiting notches 522, and the second limiting protrusions 1322 can prevent the end of the semicircle 52 from moving toward the first mounting hole 520, thereby realizing the radial positioning of the semicircle 52, so that the bracket 50 has good stability and reliability in fixing, and the bracket 50 can stably fix the speaker 30, the microphone 40 and the vital sign detection component 1221 in the earphone body 10, ensuring the stability and reliability of the earphone in use; in addition, the limiting method of the second limiting protrusion 1322 and the limiting notch 522 is adopted, and this method does not need to use other fixing components, reduces the number of components inside the earphone, and greatly reduces the external dimensions of the earphone.

The third limiting protrusion 134 and the fourth limiting protrusion 135 clamp the second fixing portion 53, thereby preventing the second fixing portion 53 from moving between the third limiting protrusion 134 and the fourth limiting protrusion 135, and the fixation of the vital sign detection component 1221 is stable and reliable; in addition, the third limiting protrusion 134 is inserted into the first limiting groove 533, and the third limiting protrusion 134 is limited by the side wall of the first limiting groove 533, so that the second fixing portion 53 moves relative to the bottom surface of the installation cavity 13, further ensuring the fixation stability and reliability of the vital sign detection component 1221; in addition, the limiting method of the third limiting protrusion 134, the fourth limiting protrusion 135 and the first limiting groove 533 is adopted. This method does not require the use of other fixing components, reduces the number of components inside the earphone, and greatly reduces the external dimensions of the earphone.

[0061] Furthermore, the fourth limiting protrusion 135 extends circumferentially along the second fixing portion 53, so that one side of the second fixing portion 53 can be completely pressed against the fourth limiting protrusion 135, so that the bracket 50 cannot move along the bottom surface of the installation cavity 13, and the fixing reliability of the bracket 50 is good.

[0062] Furthermore, the number of the third limiting protrusions 134 is two, three or more than three; the number of the fifth limiting protrusions 511 is two, three or more than three, and the third limiting protrusions 134 and the fourth limiting protrusions 135 are distributed at circumferential intervals along the second fixing portion 53. The more the third limiting protrusions 134 and the fourth limiting protrusions 135, the better the fixing stability of the bracket 50 in the mounting cavity 13.

The second mounting hole 531 provides an installation space for the microphone 40, and the microphone 40 is embedded in the second fixing portion 53, so that there is no need to reserve an installation height for the microphone 40 in the mounting cavity 13, thereby reducing the height of the earphone body 10, that is, reducing the height of the earphone, making the earphone more compact, more flexible to use, and more comfortable to wear; at the same time, the first tightening protrusion 136 presses against the microphone 40, thereby stably fixing the microphone 40 in the second mounting hole 531, preventing the microphone 40 from escaping from the second mounting hole 531, and the fixation of the microphone 40 is more stable and reliable; in addition, the second abutting protrusion 532 presses against the bottom surface of the mounting cavity 13, so that the entire bracket 50 can be stably pressed against the bottom surface of the mounting cavity 13, so that the fixation of the bracket 50 is more stable and reliable, and the fixation of the internal components of the earphone is more stable and reliable.

[0065] In another embodiment of the present application, see Fig. 9 , Fig.10 and Fig.11 As shown, the inner circumferential wall of the semicircular portion 52 of the provided earphone is provided with a first fixing flange 523 extending along the circumferential direction thereof, and the surface of the fixing protrusion 132 facing the semicircular portion 52 is provided with a second fixing flange 1323 extending along the circumferential direction thereof, and the two ends of the first fixing flange 523 are connected with the two ends of the second fixing flange 1323, and are surrounded to form an annular flange, and the speaker 30 is pressed against the cavity bottom surface of the annular flange facing away from the mounting cavity 13. The speaker 30 is pressed against the annular flange formed by the first fixing flange 523 and the second fixing flange 1323, so that the speaker 30 cannot move along the axial direction of the first mounting hole 520, so that the axial positioning of the speaker 30 is realized, and the positioning structure does not need to use other fixing components, reduces the number of components inside the earphone, and greatly reduces the external dimensions of the earphone.

[0066] In another embodiment of the present application, Fig. 9 and Fig.12As shown, a fifth limiting protrusion 511 and a sixth limiting protrusion 512 are provided on the first fixing portion 51 of the earphone provided, and a second limiting groove 12211 and a third limiting groove (not shown) are provided on the vital sign detection component 1221, the second limiting groove 12211 and the third limiting groove are respectively located on the opposite side surfaces of the vital sign detection component 1221, and the fifth limiting protrusion 511 and the sixth limiting protrusion 512 are respectively inserted into the second limiting groove 12211 and the third limiting groove. The fifth limiting protrusion 511 and the sixth limiting protrusion 512 are respectively inserted into the corresponding second limiting groove 12211 and the third limiting groove, so that the vital sign detection component 1221 cannot move between the fifth limiting protrusion 511 and the sixth limiting protrusion 512, thereby stably fixing the vital sign detection component 1221 in the mounting through hole 131, avoiding the vital sign detection component 1221 from moving in the radial direction of the mounting through hole 131, and ensuring that the vital sign detection component 1221 can accurately obtain the user's vital sign detection component 1221, thereby ensuring the accuracy of the detection; the limiting structure does not require the use of other fixing components, reduces the number of components inside the earphone, and greatly reduces the external dimensions of the earphone.

[0067] Furthermore, the number of the fifth limiting protrusions 511 is two, three or more than three; the number of the sixth limiting protrusions 512 is two, three or more than three, and the fifth limiting protrusions 511 and the sixth limiting protrusions 512 are distributed at intervals along the circumference of the vital signs detection component 1221. The more the fifth limiting protrusions 511 and the sixth limiting protrusions 512, the better the fixing stability of the vital signs detection component 1221 in the mounting through hole 131. The specific number and position can be selected according to actual needs and are not limited here.

[0068] Preferably, the number of the fifth limiting protrusions 511 is two; the number of the sixth limiting protrusions 512 is two, and the two fifth limiting protrusions 511 and the two sixth limiting protrusions are respectively located at the four corners of the vital signs detection component 1221, so that the radial fixation of the vital signs detection component 1221 in the mounting through hole 131 can be fully realized, so that the vital signs detection component 1221 cannot move up and down, forward and backward in the mounting through hole 131, and the fixing stability of the vital signs detection component 1221 is good.

[0069] In another embodiment of the present application, Figure 2As shown, a limiting flange 1311 is provided on the inner circumferential wall of the mounting through hole 131 of the provided earphone, and the first fixing portion 51 presses the vital sign detection component 1221 against the limiting flange 1311. The vital sign detection component 1221 is clamped between the first fixing portion 51 and the limiting flange 1311, so that the axial positioning of the vital sign detection in the mounting through hole 131 is realized. At the same time, the vital sign detection component 1221 is blocked by the limiting flange 1311, so that the vital sign detection component 1221 cannot be separated from the mounting through hole 131, thereby ensuring the accuracy and stability of the detection of the vital sign detection component 1221.

[0070] In the present embodiment, it should be noted that the earphone handle 11 is in the shape of an elongated strip, and both ends thereof are in the shape of an arc, so that the entire earphone handle 11 has a rounded appearance and is more comfortable to wear.

The ferrule 21 is sleeved on the earphone head 12, and a positioning protrusion 124 is provided on the outer peripheral wall of the earphone head 12. A positioning through hole 213 is provided on the ferrule 21, and the positioning protrusion 124 is inserted into the positioning through hole 213. When in use, the earphone head 12 is inserted into the ear canal, and the ear support 22 is inserted into the concha and pressed against the antihelix, so that the earphone is stable and reliable when worn; in addition, the first positioning protrusion 124 is inserted into the positioning through hole 213, so that the ferrule 21 can be completely fixed, so that the ferrule 21 cannot rotate at all, and the ear support 22 cannot rotate when worn, so that the earphone is stable and reliable when worn.

[0073] Further, see Figure 7 and Figure 8As shown, a mounting protrusion 123 is provided on the outer peripheral wall of the earphone head 12, and a second groove 212 is provided at a position corresponding to the root of the inner peripheral wall of the ring 21 and the ear support 22. The second groove 212 extends to the root of the ear support 22, and the mounting protrusion 123 is inserted into the second groove 212, which can further prevent the ring 21 from rotating and improve the wearing stability and reliability; in addition, during specific use, the second groove 212 extends to the root of the ear support 22, and the depth of the second groove 212 is deep, so the depth of the mounting protrusion 123 inserted into the second groove 212 is also deeper, and the mounting protrusion 123 has a better limiting effect on the ring 21, and the ring 21 is difficult to rotate relative to the earphone head 12, so that the ear support 22 is better and more stable in adaptability to the shape of the ear, and the comfort and stability of the earphone are better.

[0074] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, a headset is provided with a boss 122 on the outer peripheral wall of the earphone head 12, and a vital sign detection component 1221 is arranged in the boss 122; a protrusion 211 is arranged on the outer peripheral wall of the ring 21, the protrusion 211 is sleeved on the installation protrusion 123, and is used to press against the anti-auricular tragus, and a gap-avoiding through hole 2111 is arranged on the end face of the protrusion 211, and the detection end of the vital sign detection component 1221 is arranged opposite to the gap-avoiding through hole 2111, and is used to detect the vital sign parameters of the user; the ear support 22 is in the shape of a horn sheet, and the root of the ear support 22 is connected to the outer peripheral wall of the ring 21, wherein the ear support 22 extends outward from the outer peripheral wall of the ring 21 along the circumferential direction of the ring 21.

[0075] The earphones of the present application embodiment refer to Fig.13 and Fig.14 As shown, when wearing, first insert the ear cap 1211 into the ear canal and put it in place, then the earphone head 12 is located in the concha cavity, and the earphone handle 11 is located outside the concha cavity. The user pinches the earphone handle 11 and rotates the entire earphone body 10 to insert the ear support 22 into the concha boat. When the ear support 22 is inserted into the concha boat and puts in place, the end face of the raised portion 211 on the ring 21 presses against the antitragus, thereby realizing the wearing of the earphone; when the earphone is worn, the detection end of the heart rate and blood oxygen component can directly obtain the heart rate and blood oxygen data at the antitragus through the air-avoiding through hole 2111, thus realizing the user's health monitoring. Health status monitoring; at the same time, after the earphone is worn, the ear cap 1211 rests against the ear canal, the end face of the protrusion 211 presses against the antitragus, and the ear support 22 presses against the antihelix, so that the support points of the ear cap 1211, the protrusion 211 and the ear support 22 form an equilateral triangle stress state of about 60°. This triangular stress state is stable and reliable, thereby greatly improving the stability and reliability of the earphone, thereby preventing the movement of the heart rate and blood oxygen component detection position, and ensuring the accuracy of the monitoring data.

[0076] Specifically, see Figure 1 and Figure 4 As shown, the ear support 22 is in the shape of a horn sheet, and its root width is large, and the width of the ear support 22 decreases as it moves toward the tip. The root can provide sufficient support for the ear support 22 to ensure the stability and reliability of the earphone when worn. The thinner the tip is, the better the deformation effect of the tip is, so that it can adapt to the hyoid tube and antihelix with more complex shapes and structures, thereby improving the overall wearing comfort. The ear support 22 of this shape allows the overall wearing feeling to achieve a balance between support and comfort.

[0077] Furthermore, the ox-horn sheet-shaped ear support 22 has a better force-bearing area and better supporting force than the ordinary U-shaped ear support 22 or the ox-horn columnar ear support 22; the specific reasons are as follows: the U-shaped ear support 22 has a narrow force point and a strong pressure, which can easily cause local pain; the ox-horn columnar ear support 22 has a too thin root and too large deformation, which can easily cause insufficient supporting force, resulting in the movement and deviation of the vital sign detection component 1221, and then leading to the problem of poor accuracy of the monitoring data.

[0078] For further information, see Figure 5 As shown, the ear support 22 is tilted relative to a plane perpendicular to the axis of the earphone head 12, and the tip of the ear support 22 is tilted relative to the root of the ear support 22 toward the earphone head 12. When in use, the ear support 22 is tilted toward the ear, so that the ear support 22 can be inserted into the concha more easily, making it easier to wear. At the same time, when the ear support 22 is tilted toward the ear, it can also be more matched and embedded in the concha, increasing comfort and stability.

[0079] For further information, see Figure 5 As shown, the deflection tilt angle α1 of the ear support 22 relative to the plane perpendicular to the axis of the earphone head 12 ranges from 12° to 16°. Setting the deflection tilt angle α1 within the above range ensures that the ear support 22 can be easily inserted into the concha cylindrica, making the wearing operation of the earphone easier. In addition, after the ear support 22 is tilted, the matching degree with the arc of the antihelix is ​​high, which improves the wearing stability and reliability; in addition, if the preset angle is set too small, that is, less than 12°, the ear support 22 is not easy to be inserted into the concha cylindrica, and is easily exposed outside the concha cylindrica, and cannot play a fixing role; on the contrary, if the preset angle is set too large, that is, greater than 16°, the tip of the ear support 22 is easy to be too deep against the top of the concha cylindrica, resulting in a decrease in the comfort of wearing the earphone; specifically, the deflection tilt angle α1 can be 12°, 12.5°, 13°, 13.5°, 14°, 14.5°, 15°, 15.5° or 16°.

[0080] Preferably, the deflection tilt angle α1 is 14.62°. When the deflection tilt angle α1 is set at 14.62°, the ear support 22 can be inserted into the concha cylindrica and can fully adapt to the shape of the concha cylindrica without squeezing the ear, thereby greatly improving the wearing comfort of the earphone. In addition, it can also ensure that the ear support 22 can be stably pressed against the antihelix, further improving the wearing reliability and stability.

[0081] In this embodiment, refer to Figure 6 As shown, the sound mouthpiece 121 is eccentrically arranged on the end surface of the earphone head 12 facing away from the earphone head 12, and the sound mouthpiece 121 is used to guide the sound emitted by the speaker 30 into the ear canal of the user, wherein the ear cap 1211 is made of silicone material, which is soft and improves the comfort of wearing the earphone.

[0082] In the present embodiment, the earphone set 20 is a silicone earphone set; specifically, the ferrule 21 and the ear support 22 are made of silicone material by one-piece injection molding, which is easy to manufacture, and the material is soft and comfortable to wear.

[0083] In this embodiment, refer to Figure 3 As shown, the mounting through hole 131 is arranged in the end face of the boss 122, and the vital sign detection component 1221 is embedded in the mounting through hole 131. The detection end of the vital sign detection component 1221 is exposed from the air-avoiding through hole 2111 formed by the limiting flange 1311. The light emitted by the detection end of the vital sign detection component 1221 passes through the air-avoiding through hole 2111 and then enters the subcutaneous tissue of the antitragus. Then, the hemoglobin in the blood absorbs the green light or the red light, and the intensity of the reflected light changes, so that the optical signal is converted into an electrical signal and the vital sign information can be obtained after amplification, thereby realizing the user's heart rate and blood oxygen detection. Specifically, the vital sign detection component 1221 can be a heart rate and blood oxygen detection component.

[0084] In another embodiment of the present application, see Figure 4As shown, the ear support 22 of the provided earphone is provided with a first groove 221 in the middle of the side facing the mouthpiece 121, the first groove 221 is in the shape of a bull horn, and the first groove 221 extends from the ferrule 21 along the extension direction of the ear support 22, and the root of the first groove 221 is closer to the ferrule 21 than the tip of the first groove 221. Specifically, the ear support 22 in the shape of a bull horn has a large surface area, and the first groove 221 in the middle thereof has a large deformation on the basis of ensuring that the ear support 22 has sufficient supporting force, so that after the earphone is worn, the force is evenly applied, and the wearing comfort is better; in addition, the setting of the first groove 221 can reduce the accumulation of materials of the ear support 22, so that the thickness range of the ear support 22 is set within a reasonable range. If the ear support 22 is too thick, the protrusion 211 will press against the antitragus and cause pain; if the ear support 22 is too thin, the vital sign detection component 1221 will not be accurately positioned, and it is easy to loosen and dislocate.

[0085] Furthermore, the first groove 221 is also horn-shaped and is adapted to the shape of the ear support 22, that is, the root of the ear support 22 is large, and the size of the first groove 221 arranged at the root of the ear support 22 is also large, and the tip of the ear support 22 is small, and the size of the first groove 221 arranged at the tip of the ear support 22 is also small. In this way, the material of the entire ear support 22 is evenly distributed, and the entire ear support 22 has sufficient supporting force while also having a large and uniform deformation. In this way, after being worn in the ear, the deformation is uniform, the force is uniform, and the wearing comfort is better.

[0086] In another embodiment of the present application, see Figure 4As shown, the ear support 22 of the provided earphone has a thickness range of 0.8mm to 1.2mm at the middle position of the bottom surface of the first groove 221, and a thickness range of 1.75mm to 1.95mm at the opening edge of the first groove 221. The ear support 22 is thin in the middle, so that the ear support 22 has good deformation ability, and the thick structure on both sides makes the ear support 22 have sufficient support force to ensure the stability and reliability of the earphone wearing; specifically, the thickness of the ear support 22 at the middle position of the bottom surface of the first groove 221 can be 0.8mm, 0.85mm, 0.9mm, 0.95mm, 0.1mm, 0.15mm or 1.2mm. If the thickness of the ear support 22 at the middle position of the bottom surface of the first groove 221 is too large, the deformation ability of the ear support 22 is poor, and the wearing comfort is poor; if the ear support 22 is thick at the middle position of the bottom surface of the first groove 221, the ear support 22 is thin at the middle position of the bottom surface of the first groove 221, and the ear support 22 is thin at the middle position of the bottom surface of the first groove 221. If the thickness of the ear support 22 at the middle position of the bottom surface of the first groove 221 is set too small, the ear support 22 is difficult to manufacture and the cost is high; the thickness of the ear support 22 at the opening edge of the first groove 221 can be 1.75mm, 1.8mm, 1.85mm, 1.9mm or 1.95mm. If the thickness of the ear support 22 at the opening edge of the first groove 221 is set too large, the deformation ability of the ear support 22 is poor and the wearing comfort is poor; if the thickness of the ear support 22 at the opening edge of the first groove 221 is set too small, the ear support 22 cannot play a good supporting role, resulting in poor wearing stability and reliability of the earphone.

[0087] In this embodiment, the cross-section of the first groove 221 is in a U-arc shape. In the cross-section, the thickness of the entire ear support 22 increases evenly from the apex of the U-arc to the edge of the ear support 22. The material distribution of the ear support 22 is reasonable. After the earphone is put into the ear, the ear support 22 is evenly deformed and evenly stressed, and the wearing comfort is better.

[0088] Preferably, the thickness of the ear support 22 at the apex of the U-arc is 1 mm, and the thickness at the opening of the first groove 221 is 1.85 mm. The design of the above dimensions can maximize the balance between the stability and comfort of wearing the earphones.

[0089] In another embodiment of the present application, see Figure 4 As shown, the distance L1 between the end face of the raised portion 211 of the provided earphone and the farthest point of the ferrule 21 from the raised portion 211 is less than 17 mm. The smaller the distance L1 between the farthest point of the raised portion 211 and the end face of the raised portion 211, the less abrupt feeling the earphone will feel after being worn, and the better the wearing comfort. In the specific manufacturing process, the above distance value is designed to be within 17 mm mainly by adopting a thinner vital sign detection component 1221 and, on the basis of ensuring wearing comfort, using a ferrule 21 with a smaller thickness as much as possible. Specifically, when the end face of the raised portion 211 is an arc surface, the distance L1 is the distance between the vertex of the arc surface and the farthest point.

[0090] In another embodiment of the present application, see Figure 4 As shown, the height L2 of the protruding portion 211 of the provided earphone is less than or equal to 1.36 mm. The protruding height L2 of the protruding portion 211 is set within a range of less than or equal to 1.36 mm, so that the diameter of the ring 21 can be designed to be larger, so that when worn, the outer peripheral wall of the ring 21 facing away from the protruding portion 211 can be pressed against the side wall of the concha cavity, and the contact area between the ring 21 and the side wall of the concha cavity is larger, and the wearing comfort is better. At the same time, the stability, reliability and comfort of the protruding portion 211 pressed against the antitragus are better, and the detection result of the vital sign detection component 1221 will be more accurate. Preferably, the height L2 is 1.36 mm.

[0091] Preferably, the distance L1 between the end surface of the protrusion 211 and the farthest point of the ferrule 21 from the protrusion 211 is 16.69 mm.

[0092] In another embodiment of the present application, see Figure 4 As shown, the distance L3 between the end surface of the protrusion 211 of the earphone and the tip vertex of the ear support 22 is in the range of 20 mm to 28 mm. Specifically, the distance L3 between the end surface of the protrusion 211 and the tip vertex of the ear support 22 can be 20 mm, 20.5 mm, 21 mm, 21.5 mm, 22 mm, 22.5 mm, 23 mm, 23.5 mm, 24 mm, 24.5 mm, 25 mm, 25.5 mm, 26 mm, 26.5 mm, 27 mm, 27.5 mm or 28 mm. When the distance L3 is set within the above range, the earphone is stable and reliable to wear, and the comfort is high, and it can also meet the wearing needs of most Asian ears. More specifically, when the end surface of the protrusion 211 is a curved surface, the distance L3 is the distance between the vertex of the curved surface and the tip vertex of the ear support 22.

[0093] Preferably, the distance L3 between the end surface of the protrusion 211 and the tip apex of the ear support 22 can be 20.71 mm, 23.69 mm and 26.51 mm. The earphone kits 20 of these three sizes can meet the wearing requirements of most Asian ears.

[0094] In another embodiment of the present application, see Figure 4As shown, the distance L4 from the farthest point of the ear support 22 of the earphone to the symmetric center line CC of the ring 21 is 10mm to 14mm. Specifically, the distance L4 from the farthest point of the ear support 22 to the symmetric center line CC of the ring 21 can be 10mm, 10.2mm, 10.4mm, 10.6mm, 10.8mm, 11mm, 11.2mm, 11.4mm, 11.6mm, 11.8mm, 12mm, 12.2mm, 12.4mm, 12.6mm, 12.8mm, 13mm, 13.2mm, 13.4mm, 13.6mm, 13.8mm or 14mm. Setting the distance L4 within the above range can meet the ear size adaptation of most people, ensure that when the earphone is worn, the ear support 22 can be stably pressed against the antihelix, so that the wearing is reliable and more stable.

[0095] Preferably, the distance L4 between the end surface of the protrusion 211 and the tip of the ear support 22 can be 11.42 mm, 12.53 mm and 13.2 mm. The earphone kits 20 of these three sizes can meet the wearing requirements of most Asian ears.

[0096] In another embodiment of the present application, see Figure 6 As shown, the angle between the symmetry center line DD of the ferrule 21 of the provided earphone and the axis of the mouthpiece 121 is in the range of 90° to 115°. Specifically, the angle α2 between the symmetry center line DD of the ferrule 21 and the axis of the mouthpiece 121 is 90°, 92°, 94°, 96°, 98°, 100°, 102°, 104°, 106°, 108°, 110°, 112°, 114° or 115°. Setting the angle α2 within the above range can adapt to the ear shape of most people, ensure the stability and comfort of the ear cap 1211 against the ear canal, and improve the stability and comfort of wearing.

[0097] Preferably, the angle α2 between the symmetry center line DD of the ferrule 21 and the axis of the mouthpiece 121 is 110°.

[0098] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
