It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions used herein are for the purpose of illustration only and do not represent the only embodiment.

Referring to FIGS. 1 , 2 and 5 , an earphone 10 provided by an embodiment of the present invention includes an ear hook 11 , an ear plug 12 and a sounding unit 13 . The ear hook 11 is curved and is located outside the ear cavity of the human ear 20 , The earhook 11 can be hung on the human ear 20 by hooking, and the sounding unit 13 is arranged in the earhook 11. The sounding unit 13 is used to generate sound, and the sounding unit 13 is commonly called a speaker. The earplugs 12 are fixed on the earhook 11, and the earplugs 12 can only be accommodated in the concha cavity 21 of the human ear 20, and the earplugs 12 cannot further extend into the ear canal. The entire earphone 10 can be stably and reliably fixed on the human ear 20 through the cooperation of the earplug 12 and the concha cavity 21 and the dual functions of the ear hook 11 and the human ear 20 being hooked.

In some embodiments, the earhook 11 includes a first segment 11b and a second segment 11c, the first segment 11b and the second segment 11c are connected by bending, and both the first segment 11b and the second segment 11c can be formed by being substantially connected by bending V-shaped. The sounding unit 13 is located in the second section 11c, and the earplugs 12 are fixed on the second section 11c. The first section 11b has a fixed end and a free end 11d oppositely arranged, the fixed end of the first section 11b is fixedly connected with the second section 11c, and the free end 11d of the first section 11b is not fixed on the second section 11c or the earplug 12 Instead, the free end 11d of the first segment 11b is spaced apart from the second segment 11c and the earplug 12 . Therefore, by arranging the free end 11d, the distance between the free end 11d and the second segment 11c and the earplug 12 can be changed, so that the space between the first segment 11b and the second segment 11c can be changed, so that the earhook 11 can be changed. It can be hung on different human ears 20 , and it is also convenient for the ear hook 11 to be hung on the human ear 20 or removed from the human ear 20 .

3, 4 and 5, the earplug 12 can be detachably connected to the earhook 11. On the one hand, when the earplug 12 fails, the earplug 12 can be unloaded from the earhook 11 for maintenance. The earplugs 12 can be re-installed on the earhook 11 . On the other hand, the earhook 11 can be matched with different types of earplugs 12 , so that the wearing of the earphone 10 can meet the individual needs of the user. For example, when a user needs to use a larger-sized earplug 12 , the smaller-sized earplug 12 installed on the earhook 11 can be unloaded first, and then the larger-sized earplug 12 can be fixed on the earhook 11 . The earplugs 12 can also be rotated relative to the earhook 11, and by rotating the earplugs 12, a better fit effect can be formed with the human ear 20, thereby improving wearing comfort.

Referring to FIGS. 5 and 6 , in some embodiments, the earplug 12 includes a plug portion 100 and a mounting portion 200 . The plug portion 100 is used to be accommodated in the concha cavity 21 of the human ear 20 , and the plug portion 100 cannot further enter. into the ear canal. The mounting portion 200 is made of the same material, and the plug portion 100 is also made of the same material. The mounting portion 200 is connected to the end of the plug portion 100 close to the earhook 11 . The plugging part 100 has good flexibility, and the softness of the plugging part 100 is uniformly set everywhere, so as to prevent the situation where one part of the plugging part 100 is relatively softer than another part. The hardness of the mounting part 200 is higher than that of the plugging part 100 . Of course, the hardness of the mounting part 200 can also be uniformly set everywhere, so as to prevent a part of the mounting part 200 from being harder than another part. The ear hook 11 is provided with a mounting hole 11a. The cross-sectional dimension of the plug portion 100 is larger than the cross-sectional dimension of the mounting portion 200. The mounting portion 200 cooperates with the mounting hole 11a and is accommodated in the mounting hole 11a. The mounting hole 11a is fitted outside the mounting hole 11a.

Both the mounting part 200 and the plugging part 100 may be integrally connected by injection molding. For example, an injection mold is first provided having a cavity for molding the entire earplug 12 . The melt is then injected into the first part of the cavity by the first injection machine, and the melt is injected into the second part of the cavity by the second injection machine. After a certain period of cooling, the molten liquid in the first part of the cavity will solidify to form the mounting part 200 with higher hardness, while the molten liquid in the second part of the cavity will solidify to form the mounting part 200 with lower hardness and higher flexibility. Finally, the mold is opened, and the molded earplugs 12 can be taken out from the filling cavity.

Through the cooperation of the mounting portion 200 with the mounting hole 11a, the entire earplug 12 can be mounted on the earhook 11. Considering that the mounting portion 200 has higher hardness relative to the plug portion 100 , the stability and reliability of the connection between the mounting portion 200 and the entire earplug 12 and the earhook 11 can be improved. The earhook 11 can form an interference fit with a certain degree of interference with the installation hole 11a , and the fixed connection between the installation part 200 and the earhook 11 can be realized by the interference fit of the installation part 200 and the installation hole 11a . The mounting portion 200 is roughly in the shape of a column, and there is a reasonable degree of interference between the mounting portion 200 and the mounting hole 11a. Under the action of an external force, the mounting portion 200 can rotate in the mounting hole 11a, so that the mounting portion 200 drives the plug The part 100 rotates relative to the ear hook 11 . Therefore, when the plug portion 100 is rotated relative to the ear hook 11, the plug portion 100 can be rotated to any desired position, so that the plug portion 100 and the human ear 20 can form a good fit effect and improve wearing comfort. At the same time, it is possible to find the best position where the plug-in portion 100 fits with the concha cavity 21, improve the tightness of the fit between the earplug 12 and the concha cavity 21, and prevent the sound in the concha cavity 21 from leaking out of the human ear 20, The sound leakage phenomenon of the earphone 10 is effectively avoided. It can also prevent external noise from entering the ear canal through the concha cavity 21 , ensuring that the earphone 10 has a greater anti-interference ability against external noise, and improving the noise reduction effect of the earphone 10 .

For different types of earplugs 12, the size of the cross-section of the plug portion 100 is different, while the size of the cross-section of the mounting portion 200 may be the same. Since the size of the mounting hole 11a on the same ear hook 11 remains unchanged, when the cross-sectional dimensions of the mounting portion 200 on the earplugs 12 of different models remain the same, it can be ensured that the mounting portions 200 on the earplugs 12 of different models can be installed in the same The holes 11a are effectively matched to ensure that different types of earplugs 12 can be installed on the earhook 11 , and finally the same earhook 11 can be adapted to the installation of different types of earplugs 12 , thereby improving the versatility of the earphone 10 .

If the entire plug portion 100 is made of a hard material, the plug portion 100 will have a higher hardness. When the earphone 10 is worn for a long time, the plug portion 100 will cause damage to the human ear 20, thereby affecting the human ear 20. The human ear 20 produces a tingling discomfort, which reduces the wearing comfort of the earphone 10 . In addition, if the hardness of the inner layer material of the plug portion 100 is relatively high and the outer layer material is relatively soft, that is, the softness of the entire plug portion 100 is not uniformly set, under the action of external force, the elastic deformation of the inner layer material will be much smaller than that of the outer layer material. The amount of deformation of the outer layer material reduces the total elastic deformation of the entire plug portion 100, making it difficult for the plug portion 100 to generate a reasonable amount of elastic deformation to fit the concha cavity 21 with an incompatible space, resulting in the plug portion 100 being difficult for human beings. The ear 20 is greatly compressed, so that the plug portion 100 cannot form a good fit effect with the human ear 20 , which ultimately affects the wearing comfort of the earphone 10 . Furthermore, if the sounding unit 13 is directly arranged in the plug part 100, that is, the plugging part 100 is set outside the sounding unit 13, the sounding unit 13 will be accommodated in the concha cavity 21 following the plugging part 100, so on the one hand Make the sounding unit 13 close to the ear canal, the electromagnetic radiation generated by the sounding unit 13 will cause harm to the human body; The amount of elastic deformation also causes the plug portion 100 to greatly oppress the human ear 20 , and also makes the plug portion 100 unable to form a good fit effect with the human ear 20 , which ultimately affects the wearing comfort of the earphone 10 .

For the earplug 12 in the above embodiment, the mounting portion 200 with higher hardness cannot enter the concha cavity 21 , and only the inserting portion 100 with higher flexibility is accommodated in the concha cavity 21 . The plugging part 100 is made of the same material, so that the softness and hardness of the plugging part 100 are uniform and uniform everywhere, which effectively avoids the situation that one part of the plugging part 100 has higher softness than another part. In this way, under the action of the external force, the elastic deformation of the inner layer and the outer layer of the plug portion 100 is kept the same, and the elastic deformation of the entire plug portion 100 can be greatly increased, so that the plug portion 100 can generate a reasonable amount of elastic deformation. The concha cavities 21 with different space sizes are used to effectively prevent the plug portion 100 from exerting great pressure on the human ear 20 , improve the fitting effect of the plug portion 100 and the human ear 20 , and finally improve the wearing comfort of the earphone 10 . And the sounding unit 13 is accommodated in the ear hook 11, preventing the sounding unit 13 from being arranged in the plug portion 100, thereby preventing the sounding unit 13 from being accommodated in the concha cavity 21, so that the sounding unit 13 is effectively prevented from being placed in the plug portion 100. The amount of elastic deformation is limited to ensure that the plug portion 100 has a large amount of elastic deformation. The second is to effectively prevent the electromagnetic radiation of the pronunciation unit 13 from entering the ear canal and causing harm to the human body.

Due to the relatively high hardness of the mounting portion 200 , on the one hand, the bending strength of the mounting portion 200 can be improved, so as to prevent the mounting portion 200 from being deformed and causing the plug portion 100 to shake, so as to ensure that the plug portion 100 is in the best position in the concha cavity 21 . It can improve the fitting effect of the plug part 100 and the sealing effect on the ear concha cavity 21 . On the other hand, when the replacement frequency of the earplugs 12 is high, the wear of the mounting portion 200 can be effectively reduced, and the fitting accuracy between the mounting portion 200 and the mounting hole 11a can be improved.

Referring to FIG. 2 , FIG. 5 and FIG. 6 , in some embodiments, the plug portion 100 is provided with a sound outlet 110 , the number of the sound outlet 110 may be one, and the diameter of the sound outlet 110 is relatively large. Sound guide holes 120 are provided on the bottom wall of the sound outlet hole 110 , and the number of sound guide holes 120 is multiple. Obviously, the diameter of the sound guide hole 120 is smaller than that of the sound outlet hole 110 , and the sound guide hole 120 penetrates the entire installation portion 200 . . When the sounding unit 13 emits sound, the sound generated by the sounding unit 13 enters the sound outlet 110 through the sound guide hole 120 , and finally the sound in the sound outlet 110 enters the human ear 20 . In other embodiments, the number of the sound outlet holes 110 may be multiple, the diameter of the sound outlet holes 110 is relatively small, and the sound outlet holes 110 penetrate the entire earplug 12 .

Referring to FIG. 9 , in some embodiments, the plug portion 100 has an abutment surface 161 , a sound exit surface 162 and an outer peripheral surface 130 . The abutting surface 161 is disposed toward the mounting hole 11 a of the earhook 11 , and the abutting surface 161 can also be in contact with the earhook 11 . The mounting portion 200 is protrudingly connected to the contact surface 161 , that is, one end of the mounting portion 200 is fixed on the contact surface 161 , and the other end of the mounting portion 200 protrudes from the contact surface 161 by a certain distance. The sound exit surface 162 and the contact surface 161 are spaced apart from each other along the axial direction of the earplug 12. The sound exit surface 162 is disposed away from the mounting hole 11a of the ear hook 11, which can be understood as the contact surface 161 and the sound exit surface 162. facing opposite. The sound outlet 110 is disposed on the sound outlet surface 162 , that is, the sound outlet 110 penetrates through the sound outlet surface 162 . Both the contact surface 161 and the sound exit surface 162 may be planes, the angle α between the contact surface 161 and the sound exit surface 162 is 0° to 45°, and the specific value of the angle α may be 0° , 10°, 35° or 45°. When the included angle α is 0°, it can be understood that the contact surface 161 and the sound exit surface 162 are parallel to each other. By arranging the sound outlet surface 162 and the abutting surface 161 at an angle, the plug portion 100 is better ergonomically arranged, which can not only improve the wearing comfort of the earphone 10 but also improve the stability and reliability of the earphone 10 being fixed. , it can also improve the tightness of the fit between the plug portion 100 and the concha cavity 21 , further avoid sound leakage and improve the noise reduction effect of the earphone 10 . In other embodiments, the contact surface 161 may be a curved surface, and the sound exit surface 162 may also be a convex surface.

Referring to FIG. 5 , in some embodiments, the outer peripheral surface 130 includes a first peripheral surface 131 and a second peripheral surface 132 . Both the first peripheral surface 131 and the second peripheral surface 132 are arranged along the axial direction of the earplug 12 . One end of the peripheral surface 132 is connected to the contact surface 161, the other end of the second peripheral surface 132 is connected to the first peripheral surface 131, and the sound outlet surface 162 is connected to the first peripheral surface 131, so that the first peripheral surface 131 is connected to the second peripheral surface 131. Between the peripheral surface 132 and the sound exit surface. The axial length of the first peripheral surface 131 may be greater than or equal to the axial length of the second peripheral surface 132 . For example, the axial length of the first peripheral surface 131 may be slightly greater than the axial length of the second peripheral surface 132 . The difference in the lengths may be 0.1 mm to 1 mm. In FIG. 5 , the portion between the thin dotted arrow and the contact surface 161 is the second peripheral surface 132 , and the portion between the thin dotted arrow and the sound exit surface 162 is the first peripheral surface 131 . Taking the longitudinal section of the mounting portion 200 as a reference, it is obvious that the longitudinal section passes through the central axis 330 of the mounting portion 200 , the intersection of the longitudinal section and the first peripheral surface 131 is the first intersection 1311 , and the longitudinal section and the second peripheral surface 132 The intersection line is the second intersection line 1321. The second intersection 1321 may be a curve, the first intersection 1311 is a circular arc, and the first intersection 1311 is tangent to the second intersection 1321 at the connection, that is, the first intersection 1311 and the second intersection 1321 are smoothly connected , so that the first peripheral surface 131 and the second peripheral surface 132 are connected smoothly at the connection between the two, thereby eliminating the sharp edges and corners of the connection between the two. Of course, the first peripheral surface 131 and the sound outlet surface 162 are also connected at The smooth connection at the joint also eliminates sharp edges and corners at the joint, preventing the edges and corners from causing damage to the human ear 20 and improving the wearing comfort of the plug portion 100 .

From the mounting portion 200 to the plug portion 100 along the central axis 330 of the mounting portion 200 , the distance from the first peripheral surface 131 to the central axis 330 first increases and then decreases, and the distance from the second peripheral surface 132 to the central axis 330 increases. Obviously, the distance from the first intersection line 1311 to the central axis 330 first increases and then decreases, and the distance from the second intersection line 1321 to the central axis 330 increases.

Referring to FIGS. 4 and 5 , in some embodiments, the second segment 11 c of the ear hook 11 has a convex arc surface 300 , the convex arc surface 300 is disposed toward the plug portion 100 , and the convex arc surface 300 includes a mounting surface 320 and a mating surface 310, the mating surface 310 is arranged around the mounting surface 320, the mounting hole 11a is opened on the mounting surface 320, the mounting surface 320 and the abutting surface 161 abut each other, so that the mounting surface 320 is located within the coverage of the abutting surface 161, and the The face 310 is outside the coverage of the abutment face 161 . From the mounting portion 200 to the plug portion 100 along the central axis 330 of the mounting portion 200 , the distance from the mating surface 310 to the central axis 330 gradually decreases. The longitudinal section and the mating surface 310 form a third intersection 1331 , along the central axis 330 of the mounting portion 200 from the mounting portion 200 to the plug portion 100 , and the distance from the third intersection 1331 to the central axis 330 also decreases gradually. The end of the second peripheral surface 132 is in contact with the mating surface 310 , so that the end of the second intersection 1321 and the end of the third intersection 1331 are butted, and both the second intersection 1321 and the third intersection 1331 are approximately Connect in a V shape. Therefore, an annular recessed space 133 is formed between the mating surface 310 and the second peripheral surface 132 . The cross-sectional profile of the recessed space 133 is substantially V-shaped, and the recessed space 133 is used for matching with the tragus or the antitragus.

After the insertion part 100 is accommodated in the concha cavity 21 , the tragus and the antitragus can cooperate with the recessed space 133 , so that the tragus and the antitragus can limit and fix the insertion part 100 . In this way, on the one hand, the fitting effect of the plug portion 100 to the human ear 20 can be improved; on the other hand, the stability and reliability of the entire earphone 10 can be improved to prevent the earphone 10 from being separated from the human ear 20 under the action of external impact.

The sound outlet surface 162 and the first peripheral surface 131 are located on the first plugging section 140, the abutting surface 161 and the second peripheral surface 132 are located on the second plugging section 150, and the cross-sectional dimension of the first plugging section 140 Greater than the cross-sectional dimension of the second plug segment 150 . This design mode of the plug portion 100 can effectively form the above-mentioned concave space 133 , and also makes a larger abutting force formed between the first plug portion 140 with a larger cross-sectional size and the human ear 20 , thereby improving the stability of the entire earphone 10 to be fixed. reliability.
