[0024] Figure 1The schematic diagram of the structure of an earphone 10 according to an embodiment of the present invention is shown. This embodiment takes an in-ear earphone 10 as an example to describe the earphone 10 according to the present invention. The earphone 10 can be a wired or wireless in-ear earphone 10, which can be connected to a mobile phone, a computer, an MP3 player, a wearable audio device, etc. It is worth understanding that the earphone 10 can also be designed in other forms, such as a circumaural earphone 10, etc., without departing from the concept of the present invention.

[0025] The earphone 10 may include an earphone body 100 , an ear cap 200 and an ear wing 300 , and the ear cap 200 and the ear wing 300 are detachably connected to the earphone body 100 .

[0026] Please refer to Figure 2 The earphone body 100 may include a main shell 110 and a sound outlet pipe 120, wherein the sound outlet pipe 120 is connected to the main shell 110, and the main shell 110 and the sound outlet pipe 120 may be integrally formed by injection molding, or may be set as a split structure, and fixedly connected by a snap-on or connector. The sound outlet pipe 120 has a sound channel (not shown in the figure), and a sound outlet hole 122 connected to the sound channel is provided at the end of the sound outlet pipe 120. The main shell 110 may be provided with a receiving cavity, and the sound channel is connected to the receiving cavity (not shown in the figure). The earphone 10 may also include an electronic control module 700 and a speaker 600, etc. The speaker 600 is arranged in the sound outlet pipe 120, and can transmit sound to the outside through the sound outlet pipe 120, and the electronic control module 700 is arranged in the receiving cavity. Among them, the electronic control module 700 may include an electronic control board, a battery, etc. In some structural forms, the axial direction of the sound outlet tube 120 is set at an angle to the extension direction of the main shell 110, and the main shell 110 is flat, and the electronic control module 700 can be arranged as a flat block structure or a box structure to adapt to the shape of the main shell 110. Such a setting can make the overall structure of the earphone 10 relatively small, which is convenient for combining the earphone 10 into the ear position and does not protrude too much to the outside of the ear, which is particularly suitable for use during sleep.

[0027] The ear cap 200 has a sound outlet channel 230, and the ear cap 200 includes a fixed portion 210 and a first noise reduction portion 220 connected to each other. When the fixed portion 210 is sleeved on the sound outlet tube 120, the sound outlet channel 230 is connected to the sound outlet hole 122, and the first noise reduction portion 220 is arranged around the circumference of the sound outlet tube 120. When worn, the ear cap 200 extends into the ear canal, and the sound played by the speaker 600 can be transmitted to the ear canal through the sound channel, the sound outlet hole 122 and the sound outlet channel 230 in sequence. The specific working principle of the earphone 10 has long been disclosed in the relevant technology, and this application will not repeat it.

[0028] The ear wing 300 includes a mounting portion 310 and a second noise reduction portion 320, wherein the mounting portion 310 and the second noise reduction portion 320 are connected, the mounting portion 310 is connected to the main housing 110, and the second noise reduction portion 320 is arranged around the circumference of the main housing 110. Further, the ear wing 300 includes an ear support 330, which is located at one end of the mounting portion 310 away from the second noise reduction portion 320; in other words, in the circumference of the earphone 10, the end of the ear wing 300 away from the mounting portion 310 is provided with an outwardly protruding ear support 330, and the ear support 330 is configured to abut against the antihelix when the ear wing 300 is located in the concha cavity. The ear support 330 is mainly used to fix the earphone 10 on the ear and provide additional stability and comfort. When in use, by inserting the ear wing 300 into the auricle, the earphone 10 can be better fitted to the ear, and the earphone 10 can be prevented from falling or shaking during sports or other activities.

[0029] In this application, please see Figure 3 , the first noise reduction part 220 is arranged on the ear cap 200, and the second noise reduction part 320 is arranged on the ear wing 300. A noise reduction cavity 400 is constructed between the first noise reduction part 220 and the second noise reduction part 320, and the noise reduction cavity 400 is used to block the ambient noise entering the user's ear hole. Since the ear cap 200 and the ear wing 300 are independent components, they can be freely disassembled and replaced. The user can choose the appropriate size according to the size of their own ear canal, thereby improving the wearing comfort of the headset 10.

[0030] In some embodiments, the first noise reduction part 220 abuts against the second noise reduction part 320, and the first noise reduction part 220, the second noise reduction part 320 and the outer wall of the earphone body 100 jointly enclose a noise reduction cavity 400. It can be understood that the abutment between the first noise reduction part 220 and the second noise reduction part 320 can be that the free end of the first noise reduction part 220 away from the fixing part 210 abuts against the outer surface of the second noise reduction part 320; or the free end of the second noise reduction part 320 away from the mounting part 310 abuts against the inner surface of the first noise reduction part 220. Here, the present application does not limit the specific form of the abutment between the first noise reduction part 220 and the second noise reduction part 320.

[0031] It should be noted that, in a natural state, the first noise reduction portion 220 and the second noise reduction portion 320 may or may not abut each other, that is, the first noise reduction portion 220 and the second noise reduction portion 320 may have a gap, and the present application is not limited to this. In the wearing state, the first noise reduction portion 220 is squeezed and formed by the inner wall of the ear canal, thereby abutting against the second noise reduction portion 320 to form a noise reduction cavity 400. When the user wears the earphone 10 of the present application, part of the external noise will be intercepted by the second noise reduction portion 320, and part will enter the noise reduction cavity 400. This part of the noise is damped, absorbed and attenuated in the noise reduction cavity 400, and it will also be distorted, reducing its energy and frequency characteristics, making it difficult to penetrate the first noise reduction portion 220 and enter the user's ear canal.

[0032] It is further explained that the noise reduction chamber 400 can be formed by the outer wall of the first noise reduction part 220, the second noise reduction part 320 and the sound outlet pipe 120, or by the first noise reduction part 220, the second noise reduction part 320, the outer wall of the sound outlet pipe 120 and part of the outer wall of the main shell 110, or by the first noise reduction part 220 and the second noise reduction part 320. In the form in which the first noise reduction part 220 and the second noise reduction part 320 are jointly enclosed to form the noise reduction chamber 400, the fixing part 210 covers the outer wall of the sound outlet pipe 120, the mounting part 310 and the fixing part 210 can be in contact, and the free end of the first noise reduction part 220 (i.e., the end away from the fixing part 210) and the free end of the second noise reduction part 320 (i.e., the end away from the mounting part 310) are in contact, so that the first noise reduction part 220 and the second noise reduction part 320 can be jointly enclosed to form the noise reduction chamber 400.

[0033] In order to improve the stability when the first noise reduction part 220 and the second noise reduction part 320 are in contact, the outer end surface 221 of the first noise reduction part 220 away from the fixing part 210 does not exceed the outer end of the second noise reduction part 320 away from the mounting part 310. That is, in a natural state, the outer end surface 221 of the first noise reduction part 220 away from the fixing part 210 abuts against the second noise reduction part 320; in a wearing state, even if the first noise reduction part 220 is extended into the ear canal and is subjected to a part of pressure, causing the outer end surface 221 of the first noise reduction part 220 away from the fixing part 210 to shrink and deform, at this time, the outer end surface 221 of the first noise reduction part 220 away from the fixing part 210 always abuts against the second noise reduction part 320, thereby effectively improving the sealing performance of the noise reduction cavity 400.

[0034] It can be understood that the noise reduction chamber 400 is used to damp, absorb and attenuate noise. Therefore, in the embodiment of the present application, the noise reduction chamber 400 is arranged around the sound outlet pipe 120, which can isolate noise from all directions and further improve the noise reduction effect of the earphone 10 of the present application. Any earphone 10 discussed above or below can be provided with the noise reduction chamber 400 around the sound outlet pipe 120. Of course, in some structural forms, the noise reduction chamber 400 can also be provided only in the direction where noise is more likely to enter.

[0035] See also Figure 2 , in the axial direction E of the sound outlet tube 120 and in the direction away from the main shell 110, the outer diameter of the first noise reduction part 220 and the outer diameter of the second noise reduction part 320 are both reduced. It should be noted that the outer diameter of the first noise reduction part 220 is reduced in the axial direction E of the sound outlet tube 120 and in the direction away from the main shell 110, which can adapt to the shape of the ear canal during wearing and is more comfortable to wear. However, during wearing, the first noise reduction part 220 may be squeezed by the ear canal and shrink and deform. In the present application, the outer diameter of the second noise reduction part 320 is also set to gradually decrease in the axial direction E of the sound outlet tube 120 and in the direction away from the main shell 110, so that the supporting force of the second noise reduction part 320 on the first noise reduction part 220 can be reduced when the first noise reduction part 220 and the second noise reduction part 320 are in contact, so as to avoid the first noise reduction part 220 from being difficult to deform in the ear canal and reduce the comfort when wearing. Moreover, such a setting can also make the sealing of the noise reduction cavity 400 better. Of course, in some other structural forms, the second noise reduction part 320 can also be horizontally arranged in the axial direction of the sound outlet pipe 120. In this case, when the first noise reduction part 220 is connected to the second noise reduction part 320, they can form a triangular support state, and at the same time, they can also maintain a well-sealed noise reduction cavity 400.

[0036] In some embodiments of this application, please refer to Fig.11 The second noise reduction part 320 is located on the side of the first noise reduction part 220 facing the main shell 110, and the second noise reduction part 320 is configured to be raised in the middle toward the sound outlet 122. With this arrangement, the free end of the second noise reduction part 320 has a tendency to deform inward, and because the middle part is raised, it can also provide elastic force for the free end of the second noise reduction part 320 to deform outward. With this arrangement, the second noise reduction part 320 has good flexibility. In this way, when the first noise reduction part 220 is squeezed by the ear during wearing, the second noise reduction part 320 can deform linearly according to the force conditions, thereby improving the comfort and sealing of the user when wearing.

[0037] In some embodiments, the hardness of the second noise reduction portion 320 is greater than the hardness of the first noise reduction portion 220. Specifically, the first noise reduction portion 220 abuts against the second noise reduction portion 320 to form a closed noise reduction cavity 400. Therefore, in order to ensure the airtightness of the abutment between the first noise reduction portion 220 and the second noise reduction portion 320 when worn, the hardness of the second noise reduction portion 320 can be slightly greater than the hardness of the first noise reduction portion 220. In this way, the second noise reduction portion 320 has a certain supporting ability for the first noise reduction portion 220, so that the sealing effect of the noise reduction cavity 400 is higher, which can improve the noise reduction effect.

[0038] Furthermore, the first noise reduction portion 220 may extend from the side of the sound outlet pipe 120 away from the main shell 110 toward the side of the sound outlet pipe 120 close to the main shell 110, and the second noise reduction portion 320 may extend from the connection between the sound outlet pipe 120 and the main shell 110 toward the side of the main shell away from the sound outlet pipe 120. In this way, a noise reduction cavity 400 having a radial length slightly larger than the sound outlet pipe 120 may be formed on the outside of the sound outlet pipe 120. In this way, the volume of the noise reduction cavity 400 may be set to be relatively large, which may effectively increase the area of ​​the noise reduction cavity 400 surrounding the sound outlet pipe 120, thereby improving the noise reduction effect of the present application.

[0039] In order to further improve the sealing performance of the noise reduction chamber 400, thereby improving the noise reduction effect, the embodiments of the present application provide the following structural forms:

[0040] See also Figure 6 The outer end surface 221 of the first noise reduction portion 220 away from the fixing portion 210 is adapted to the side profile of the second noise reduction portion 320 facing the first noise reduction portion 220. Compared with the form in which one of the contact points of the outer end surface 221 of the first noise reduction portion 220 away from the fixing portion 210 abuts against the side surface of the second noise reduction portion 320 facing the first noise reduction portion 220, the present application can increase the contact area between the first noise reduction portion 220 and the second noise reduction portion 320, thereby improving the stability of the abutment between the first noise reduction portion 220 and the second noise reduction portion 320, and further improving the sealing of the noise reduction portion.

[0041] See also Figure 7 A groove 321 is formed on the side of the second noise reduction portion 320 facing the first noise reduction portion 220 . When the outer end surface 221 of the first noise reduction portion 220 away from the fixing portion 210 abuts against the groove 321 , the first noise reduction portion 220 and the groove 321 have at least two contact points. Figure 7As shown in the example, the first noise reduction part 220 has three contact points with the groove 321. The outer end surface 221 of the first noise reduction part 220 can abut the groove bottom wall of the groove 321 and / or the vertex of the groove side wall of the groove 321. The side of the first noise reduction part 220 facing the sound outlet pipe 120 abuts the vertex of the groove side wall of the groove 321. In this way, there are multiple contact points between the first noise reduction part 220 and the second noise reduction part 320, so that multiple circles of sealing lines are formed on the circumference of the noise reduction cavity 400, thereby improving the sealing and noise reduction effect of the noise reduction cavity 400. In addition, the groove 321 can make the first noise reduction part 220 stably abut against the second noise reduction part 320, further improving the sealing of the noise reduction cavity 400.

[0042] See also Figure 8 , a protrusion 322 is formed on the side of the second noise reduction part 320 facing the first noise reduction part 220, and at this time, the first noise reduction part 220 and the second noise reduction part 320 will also have two contact points. Specifically, the outer end surface 221 of the first noise reduction part 220 abuts against the second noise reduction part 320, and the side of the first noise reduction part 220 facing the sound outlet pipe 120 abuts against the protrusion 322. In this way, the first noise reduction part 220 and the second noise reduction part 320 have two contact points, thereby forming two circles of sealing lines on the circumference of the noise reduction cavity 400, which can improve the noise reduction effect. Alternatively, the protrusion 322 can be set on the side of the first noise reduction part 220 facing the second noise reduction part 320, and at this time, the outer end surface 221 of the first noise reduction part 220 and the protrusion 322 are both abutted against the second noise reduction part 320.

[0043] It should be noted that the above situations can be set in combination or one by one.

[0044] In order to achieve the noise reduction effect of the earphone 10 of the present application, the present application provides another embodiment, in which the first noise reduction part 220 and the second noise reduction part 320 are respectively in contact with different positions of the user's ear when worn. Specifically, when worn, the first noise reduction part 220 can fit the user's ear canal, and the second noise reduction part 320 can fit the surface of the user's ear. At this time, the first noise reduction part 220, the second noise reduction part 320, the user's ear, and the outer wall of the earphone body 100 will jointly enclose a noise reduction cavity 400.

[0045] It can be understood that the first noise reduction part 220 is in close contact with the ear canal and is made of a relatively soft material, which can improve the comfort of entering the ear. Moreover, it has good deformation ability and can effectively fit the user's ear canal to block the sound around the user. The fixing part 210 is used to connect with the sound outlet tube 120, and it is necessary to maintain a certain stability and shape to ensure the stability of the installation connection and prevent the ear cap 200 from falling into the ear canal when the sound outlet tube 120 is inserted into the ear canal. Therefore, the fixing part 210 can be made of a material with greater hardness. The above-mentioned materials such as silicone rubber, polyurethane or epoxy resin with different hardness. Here, the present application does not make specific restrictions on the materials of the first noise reduction part 220 and the fixing part 210.

[0046] In order to prevent the first noise reduction part 220 and the second noise reduction part 320 from sticking together during the abutment process, which affects the wearing experience, an anti-sticking agent layer is provided on the surface where the first noise reduction part 220 and the second noise reduction part 320 abut against each other. Specifically, the anti-sticking agent layer can be an oil layer formed by spraying on the surface of the first noise reduction part 220 and the second noise reduction part 320 through oil spraying treatment.

[0047] In some structural forms, the fixing portion 210 is a sleeve structure, so that the fixing portion 210 is sleeved on the outer periphery of the sound outlet tube 120. To improve the stability of the sleeve of the fixing portion 210 and the sound outlet tube 120, please refer to Figure 3 and Figure 4 The inner wall of the fixing part 210 is provided with a mounting structure 212, and the outer periphery of the sound outlet pipe 120 is provided with a fixing structure 124 adapted to the mounting structure 212. The mounting structure 212 and the fixing structure 124 are relatively fixed, so that the ear cap 200 and the sound outlet pipe 120 can be stably connected. The mounting structure 212 and the fixing structure 124 can be configured as a convex or a groove. In this way, the fixing part 210 and the sound outlet pipe 120 are connected in a snap-fit ​​manner, which can be easily disassembled and replaced.

[0048] Furthermore, a positioning structure 211 may be provided on the inner wall of the fixing portion 210, and a limiting structure 123 may be provided on the outer wall of the sound outlet tube 120. The positioning structure 211 is engaged with the limiting structure 123, which can prevent the ear cap 200 from rotating on the sound outlet tube 120, thereby improving the comfort of the user when wearing it. The positioning structure 211 and the limiting structure 123 may also be provided in the form of a convex or a groove, which is not limited in the present application. For the processing form of the ear cap 200 of the present application, secondary injection molding may be adopted, for example, the fixing portion 210 is first injection molded, and then the first noise reduction portion 220 is injection molded on the fixing portion 210; the fixing portion 210 and the first noise reduction portion 220 may also be molded separately first, and the fixing portion 210 and the first noise reduction portion 220 are connected together by adhesive bonding, hot melt connection, or the like.

[0049] See also Figure 5The first noise reduction part 220 of the present application may include a connecting section 222 and a noise reduction section 223, one end of the connecting section 222 is connected to the fixing part 210, and the other end is connected to the noise reduction section 223. The connecting section 222 at least partially extends out of the sound outlet tube 120 and is located in the axial direction E of the sound outlet tube 120 and on the side away from the main shell 110, and the connecting section 222 forms a sound outlet channel 230, and the end of the noise reduction section 223 away from the second noise reduction part 320 abuts against the inner side wall of the connecting section 222. It can be understood that at least a part of the front end of the ear cap 200 will extend into the ear canal of the user, and the first noise reduction part 220 includes the connecting section 222 located in the axial direction E of the sound outlet tube 120 and on the side away from the main shell 110, which can be located in the ear canal. Since the ear cap 200 is relatively soft, it can improve the airtightness between the user's ear canal and the ear cap 200, and can also prevent the sound outlet tube 120 from causing damage to the ear canal, thereby improving the comfort of entering the ear.

[0050] The mounting portion 310 of the ear wing 300 is sleeved on the outside of the main shell 110. It can be made of a relatively soft material to form a protective film structure, which can adapt to the shape of the main shell 110. Of course, it can also be sleeved on the main shell 110 only by the ductility of the material. In some structural forms, the second noise reduction portion 320 can cover the surface of the user's ear to form a noise reduction cavity 400, and can also abut against the first noise reduction portion 220 to form a noise reduction cavity 400. Therefore, the second noise reduction portion 320 can be made of a relatively soft material. The ear wing 300 of the present application can be made of materials such as silicone rubber, polyurethane or epoxy resin to be integrally formed.

[0051] In order to prevent the pressure in the ear canal and the front cavity from increasing and causing an occlusion effect when the sound outlet tube 120 and the ear cap 200 are extended into the ear canal when the earphone 10 is worn, thereby causing discomfort in the ear, the present application also includes a pressure relief channel 500, which connects the sound outlet hole 122 and the outside world.

[0052] See also Fig. 9In some structural forms, the pressure relief channel 500 includes a first channel section 510 and a second channel section 520 that are connected. The first channel section 510 is formed in the wall of the sound outlet pipe 120 and is connected to the sound outlet hole 122. The second channel section 520 is formed in the wall of the main shell 110 and is connected to the outside. The first channel section 510 and the second channel section 520 can be respectively recessed in the wall surface of the sound outlet pipe 120 and the wall surface of the main shell 110. In some connection methods, one end of the first channel section 510 can be connected to the sound outlet hole 122, and the other end can be connected to the noise reduction chamber 400; one end of the second channel section 520 can be connected to the noise reduction chamber 400, and the other end can be connected to the outside. In this way, if there is noise entering the pressure relief channel 500, the noise will be damped, absorbed and attenuated by the noise reduction chamber 400 first, further improving the noise reduction effect of the present application. In addition, the pressure relief channel 500 can also be an air guide tube, wherein a mounting groove is provided on the wall of the sound outlet tube 120 and the main housing 110, the air guide tube is embedded in the mounting groove, and one end is connected to the sound outlet hole 122, and the other end is connected to the outside, thereby achieving the functions of air guide and pressure relief. Here, the specific form of the pressure relief channel 500 is not limited in this application.

[0053] In order to avoid the occlusion effect caused by the increase of pressure in the ear canal and the front cavity during wearing of the earphone 10, which may cause discomfort to the ear, in addition to the scheme of setting the pressure relief channel 500 described in the above content, other means may also be adopted in the present application. In other embodiments of the present application, please refer to Fig.10 The first noise reduction part 220 is provided with a first air permeable channel 224 and a second air permeable channel 225, or the second air permeable channel 225 is provided on the second noise reduction part 320, or the second air permeable channel 225 is jointly defined by the first noise reduction part 220 and the second noise reduction part 320.

[0054] Specifically, when the free end of the first noise reduction part 220 away from the fixing part 210 abuts against the outer surface of the second noise reduction part 320, a second air permeable channel 225 is opened on the outer periphery of the first noise reduction part 220; or, when the free end of the second noise reduction part 320 away from the mounting part 310 abuts against the inner surface of the first noise reduction part 220, a second air permeable channel 225 is opened on the outer periphery of the second noise reduction part 320.

[0055] Among them, the first air permeable channel 224 is arranged closer to the sound outlet 122 than the second air permeable channel 225. In the wearing state, the first air permeable channel 224 and the second air permeable channel 225 are respectively located at the inner side and the outer side of the contact part between the first noise reduction part 220 and the ear, so that the first air permeable channel 224 connects the user's ear hole and the noise reduction cavity 400, and the second air permeable channel 225 connects the noise reduction cavity 400 and the outside. It can be understood that the outer surface of the ear cap 200 will form a relatively closed space after contacting the ear. When worn, as the ear cap 200 extends into the ear canal, the gas in the ear hole and the front cavity is squeezed, which causes the pressure of the user's ear hole to increase and produce an occlusion effect. In this application, the closed space and the noise reduction cavity 400 are connected through the first air permeable channel 224, and the second air permeable channel 225 connects the noise reduction cavity 400 and the outside. In this way, the ear hole can be depressurized during wearing to avoid user discomfort.

[0056] In some implementation forms, the first air permeable channel 224 is in the form of a through hole set through the first noise reduction part 220, and two of them can be set in radial symmetry with the sound outlet hole 122, so as to facilitate relative balance during the pressure relief process. Of course, the number of the first air permeable channels 224 can also be 1, 3, etc., and the present application does not limit this. The second air permeable channel 225 is a through groove structure that runs through the outer periphery of the first noise reduction part 220. The number of the second air permeable channels 225 can also refer to the setting form of the first air permeable channel 224. When the second air permeable channel 225 is set as a through groove structure, it has the characteristics of being more convenient to process, and also increases the deformation ability of the ear cap 200, and improves the comfort during wearing. Preferably, the present application can also stagger the second air permeable channel 225 and the first air permeable channel 224 in the circumferential direction of the ear cap 200 to avoid the adverse effect of reducing the structural strength of the ear cap 200 at the positions where the two are located when the two are too close.
