[0014] FIG. 1 is a schematic diagram showing the configuration of an earphone 10 according to an embodiment of the present invention. . Applicable The earphones 10 may be wired or wireless in-ear earphones 10, and may be communicatively connected to devices such as mobile phones, computers, MP3 players, wearable audio devices, etc. As can be appreciated, the earphones 10 may be designed in other forms, such as behind-the-ear earphones 10, without departing from the spirit of the present invention.

[0015] The earphone 10 includes an earphone body 100 and an earpiece 200. (e.g. earpieces) , and wing portion 300 (e.g., auricle) It may include stomach. The earpiece 200 and the wing portion 300 are removably connected to the earphone body 100.

[0016] As shown in FIG. 2, the earphone body 100 may include a main housing 110 and a sound emitting tube 120. stomach.The sound emitting tube 120 is connected to the main housing 110. The main housing 110 and the sound emitting tube 120 may be integrally formed by injection molding, or may be provided as separate structures fixedly connected by a fastening or connecting member or the like. The road The sound emitting tube 120 has an end provided with a sound emitting hole 122 communicating with the sound passage. The main housing 110 may have an accommodating cavity formed therein. The sound passage is and To communicate.

[0017] The earphone 10 includes an electronic control module 70 0 and beyond The earphone 10 may further include a speaker 600 and other components. The speaker 600 is provided within the sound emitting tube 120 and transmits sound to the outside via the sound emitting tube 120, and the electronic control module 700 is provided within the receiving cavity. The electronic control module 700 may include a control panel, a battery, and other components. The axial direction of the sound emitting tube 120 and the extension direction of the main housing 110 may be provided at an angle to each other. The main housing 110 may be flat, and the electronic control module 700 is disposed as a flat block-like structure or box-like structure to fit the shape of the main housing 110. When provided in this manner, the overall structure of the earphone 10 becomes relatively small, making it easy to wear the earphone 10 at the position of the ear and not protruding excessively outside the ear, making it particularly suitable for use during sleep.

[0018] The earpiece 200 has a sound emitting passage 230, and includes a fixed part 210 and a first noise canceling part 22 connected to each other. 0 When the fixing part 210 is fitted into the sound output tube 120, the sound output passage 230 communicates with the sound output hole 122, and the first noise canceling part 220 is provided surrounding the outer periphery of the sound output tube 120. In a worn state (for example, when the earphone 10 is worn by a user), the earpiece 200 is inserted into the ear canal, and sound reproduced by the speaker 600 may be transmitted to the ear canal by passing through the sound passage, the sound output hole 122, and the sound output passage 230 in that order.

[0019] The wing portion 300 includes an attachment portion 310 and a second noise canceling portion 320, and the attachment portion 310 is connected to the second noise canceling portion 320. The second noise canceling portion 320 is connected to the main housing 110 and is provided surrounding the outer periphery of the main housing 110. Furthermore, the wing portion 300 includes a support portion 330 located at the end of the attachment portion 310 away from the second noise canceling portion 320. In other words, the end of the wing portion 300 away from the attachment portion 310 in the circumferential direction of the earphone 10 is provided with the support portion 330 that protrudes outward, and the support portion 330 is positioned so as to abut against the helix when the wing portion 300 is located within the cavity of the concha. The support portion 330 is ,stomach Secures the Yaphone 10 in your ear for added stability and comfort It is possible By inserting the wing portion 300 into the ear pinna during use, the earphone 10 can be better fitted to the ear, preventing the earphone 10 from falling or swinging during exercise or other activities.

[0020] In the present application, as shown in Fig. 3, the first noise canceling section 220 is provided in the earpiece 200, while the second noise canceling section 320 is provided in the wing section 300. A noise canceling cavity 400 is provided between the first noise canceling section 220 and the second noise canceling section 320. Configuration (e.g. formation ) The noise-canceling cavity 400 blocks environmental noise from entering the user's ear canal. The earpiece 200 and the wing 300 are independent components and can be freely removed and replaced. The user can select the appropriate size based on the size of their ear canal, improving the wearing comfort of the earphone 10.

[0021] In some embodiments, the first noise canceling unit 220 abuts against the second noise canceling unit 320, and the first noise canceling unit 220, the second noise canceling unit 320, and the outer wall of the earphone body 100 surround the noise canceling cavity 400. As can be understood, the abutment of the first noise canceling unit 220 and the second noise canceling unit 320 may be such that a free end of the first noise canceling unit 220 remote from the fixing unit 210 abuts against the outer surface of the second noise canceling unit 320, or such that a free end of the second noise canceling unit 320 remote from the mounting unit 310 abuts against the inner surface of the first noise canceling unit 220. Here, the present application does not limit the specific manner in which the first noise canceling unit 220 and the second noise canceling unit 320 abut against each other.

[0022] In a natural state, the first noise canceling section 220 and the second noise canceling section 320 may abut against each other. They do not have to abut each other, i.e. , there may be a gap between the first noise canceling unit 220 and the second noise canceling unit 320. When worn, the first noise canceling section 220 is pressed by the inner wall of the ear canal and is therefore easily deformed, so that it comes into contact with the second noise canceling section 320 to form the noise canceling cavity 400 . When a user wears the earphone 10 of the present application, some external noise is blocked by the second noise canceling unit 320, and some enters the noise canceling cavity 400. This part of the noise is absorbed and attenuated by the resistance within the noise canceling cavity 400, and is also twisted, reducing its energy and frequency characteristics, making it difficult for the noise to pass through the first noise canceling unit 220 and enter the user's ear canal.

[0023] The noise canceling cavity 400 may be surrounded by the first noise canceling section 220, the second noise canceling section 320, and the outer wall of the sound emitting tube 120, or may be surrounded by the first noise canceling section 220, the second noise canceling section 320, the outer wall of the sound emitting tube 120, and part of the outer wall of the main housing 110, or may be surrounded by the first noise canceling section 220 and the second noise canceling section 320. In a configuration in which the first noise canceling section 220 and the second noise canceling section 320 surround the noise canceling cavity 400, the fixed section 210 is covered by the outer wall of the sound emitting tube 120, and the attachment section 310 abuts against the fixed section 210 and is attached to the free end ( for example , the end remote from the fixed portion 210) abuts against the free end (i.e., the end remote from the mounting portion 310) of the second noise canceling portion 320, and thus the first noise canceling portion 220 and the second noise canceling portion 320 surround the noise canceling cavity 400. and / or form It is possible.

[0024] In order to improve stability when the first noise canceling section 220 and the second noise canceling section 320 come into contact with each other, the outer end surface 221 of the first noise canceling section 220 that is remote from the fixed section 210 does not extend beyond the outer end of the second noise canceling section 320 that is remote from the mounting section 310. for example In the natural state, the outer end surface 221 of the first noise canceling unit 220 away from the fixed part 210 abuts against the second noise canceling unit 320, and in the worn state, even if the outer end surface 221 of the first noise canceling unit 220 away from the fixed part 210 of the first noise canceling unit 220 receives some pressure when inserted into the ear canal, causing the outer end surface 221 of the first noise canceling unit 220 away from the fixed part 210 to contract and deform, the outer end surface 221 of the first noise canceling unit 220 away from the fixed part 210 always abuts against the second noise canceling unit 320, thereby effectively improving the sealing performance of the noise canceling cavity 400.

[0025] As you can see, the noise cancelling cavity 400 Decline,absorption 、 and to attenuate Used for , therefore, The noise canceling cavity 400 is provided so as to surround the outer periphery of the sound emission tube 120, thereby blocking noise from all directions. ,stomach This can further improve the noise canceling effect of the earphone 10. ,of The noise canceling cavity 400 can be provided so as to surround the outer periphery of the sound emitting tube 120. .stomach In some configurations, the noise cancelling cavity 400 may only be provided in the direction where noise is more likely to enter.

[0026] 2, the outer diameters of the first noise canceling unit 220 and the second noise canceling unit 320 are both configured to decrease in the direction away from the main housing 110 along the axial direction E of the sound emitting tube 120. The outer diameter of the first noise canceling unit 220 decreases in the direction away from the main housing 110 along the axial direction E of the sound emitting tube 120, allowing it to conform to the shape of the ear canal during wear and making it more comfortable to wear. However, during wear, the first noise canceling unit 220 may be pressed by the ear canal and may shrink and deform. In the present application, the outer diameter of the second noise canceling section 320 is also gradually reduced in the direction away from the main housing 110 along the axial direction E of the sound emission tube 120, thereby reducing the support force of the second noise canceling section 320 against the first noise canceling section 220 when the first noise canceling section 220 abuts against the second noise canceling section 320, making it difficult for the first noise canceling section 220 to deform inside the ear canal and preventing a decrease in comfort when worn. Also, by providing it in this manner, the sealing of the noise canceling cavity 400 is improved. . others In some structural forms, the second noise canceling section 320 may be arranged horizontally in the axial direction of the sound emitting tube 120. In this case, the first noise canceling section 220 and the second noise canceling section 320 each other If connected (when mounted against each other) These form a triangular support state and can maintain high sealing performance of the noise canceling cavity 400.

[0027] 11 , the second noise canceling unit 320 is located on the side of the first noise canceling unit 220 facing the main housing 110, and has a middle portion protruding toward the sound output hole 122. When configured in this manner, the free end of the second noise canceling unit 320 tends to deform inward, and the protruding middle portion can provide the free end of the second noise canceling unit 320 with elasticity to deform outward. Also, when configured in this manner, the second noise canceling unit 320 has high flexibility. In this manner, when the first noise canceling unit 220 is pressed by the ear during wearing, the second noise canceling unit 320 linearly deforms based on the force received, thereby improving comfort and sealing when worn by the user.

[0028] In some embodiments, the hardness of the second noise canceling portion 320 is greater than the hardness of the first noise canceling portion 220. More specifically, since the first noise canceling portion 220 abuts against the second noise canceling portion 320 to form a sealed noise canceling cavity 400, the hardness of the second noise canceling portion 320 may be slightly greater than the hardness of the first noise canceling portion 220 to ensure a tight seal between the first noise canceling portion 220 and the second noise canceling portion 320 when worn. In this way, the second noise canceling portion 320 has a certain support ability for the first noise canceling portion 220, which improves the sealing effect of the noise canceling cavity 400 and thereby enhances the noise canceling effect.

[0029] Furthermore, the first noise canceling section 220 may extend in a direction from the side of the sound emission tube 120 away from the main housing 110 to the side of the sound emission tube 120 closer to the main housing 110, and the second noise canceling section 320 extends from the connection point between the sound emission tube 120 and the main housing 110 towards the side of the main housing away from the sound emission tube 120. This makes it possible to form a noise canceling cavity 400 on the outside of the sound emission tube 120 whose radial length is slightly larger than the radial length of the sound emission tube 120. This also makes it possible to provide a relatively large volume for the noise canceling cavity 400, which effectively increases the area of ​​the sound emission tube 120 surrounded by the noise canceling cavity 400, thereby improving the noise canceling effect of the present application.

[0030] In order to further improve the sealing of the noise canceling cavity 400 and enhance the noise canceling effect, the embodiment of the present application provides the following several structural forms.

[0031] As shown in FIG. 6, the outer end surface 221 of the first noise canceling section 220, which is far from the fixed section 210, (e.g. bottom end) In contrast to a configuration in which the second noise canceling unit 320 fits the contour of the side surface facing the first noise canceling unit 220 and one contact point on the outer end surface 221 of the first noise canceling unit 220 away from the fixed unit 210 abuts against the side surface of the second noise canceling unit 320 facing the first noise canceling unit 220, in the present application, the contact area between the first noise canceling unit 220 and the second noise canceling unit 320 is increased, thereby improving the stability of the abutment between the first noise canceling unit 220 and the second noise canceling unit 320 and further improving the sealing of the noise canceling unit.

[0032] As shown in FIG. 7, a groove 321 is formed on the side of the second noise canceling section 320 facing the first noise canceling section 220, and when the outer end surface 221 of the first noise canceling section 220 away from the fixed section 210 abuts against the groove 321, the first noise canceling section 220 and the groove 321 have at least two contact points. 7 , the first noise canceling portion 220 and the groove 321 have three contact points, with the outer end surface 221 of the first noise canceling portion 220 abutting against the bottom wall and / or the apex of the side wall of the groove 321, and the side surface of the first noise canceling portion 220 facing the sound output tube 120 abutting against the apex of the side wall of the groove 321. Thus, the multiple contact points between the first noise canceling portion 220 and the second noise canceling portion 320 form multiple sealing lines around the outer periphery of the noise canceling cavity 400, further improving the sealing performance and noise canceling effect of the noise canceling cavity 400. Furthermore, the groove 321 allows the first noise canceling portion 220 to stably abut against the second noise canceling portion 320, further improving the sealing performance of the noise canceling cavity 400.

[0033] As shown in FIG. 8 , a protrusion 322 is formed on the side of the second noise canceling unit 320 facing the first noise canceling unit 220. Even in this case, the first noise canceling unit 220 and the second noise canceling unit 320 have two contact points. Specifically, the outer end surface 221 of the first noise canceling unit 220 abuts the second noise canceling unit 320, and the side of the first noise canceling unit 220 facing the sound output tube 120 abuts the protrusion 322. In this way, the first noise canceling unit 220 and the second noise canceling unit 320 have two contact points, forming two sealing lines around the outer periphery of the noise canceling cavity 400, thereby improving the noise canceling effect. Alternatively, the protrusion 322 can be provided on the side of the first noise canceling unit 220 facing the second noise canceling unit 320. In this case, both the outer end surface 221 of the first noise canceling portion 220 and the protrusion 322 come into contact with the second noise canceling portion 320 .

[0034] It should be noted that some of the above cases may be provided in combination, or one of them may be selected and provided.

[0035] To achieve the noise canceling effect of the earphone 10 of the present application, the present application provides another embodiment in which, when worn, the first noise canceling unit 220 and the second noise canceling unit 320 each abut at different positions on the user's ear. Specifically, when worn, the first noise canceling unit 220 can be in close contact with the user's ear canal, and the second noise canceling unit 320 can be in close contact with the surface of the user's ear. In this case, the first noise canceling unit 220, the second noise canceling unit 320, the user's ear, and the outer wall of the earphone body 100 surround the noise canceling cavity 400.

[0036] As can be understood, the first noise canceling unit 220 is made of a relatively soft material that closely contacts the ear canal, improving comfort when inserted into the ear. It also has excellent deformability and can effectively fit snugly into the user's ear canal, blocking out sounds around the user. The fixing unit 210 is connected to the sound emitting tube 120 and must maintain a certain stability and shape to ensure stable attachment and connection and prevent the earpiece 200 from falling into the ear canal when the sound emitting tube 120 is inserted into the ear canal. Therefore, the fixing unit 210 is made of a material with high hardness. As mentioned above, materials with different hardnesses, such as silicone rubber, polyurethane, or epoxy resin, can be used. The present application does not specifically limit the materials of the first noise canceling unit 220 and the fixing unit 210.

[0037] To prevent the first noise canceling unit 220 and the second noise canceling unit 320 from becoming sticky during the contact process and affecting the wearing comfort, an anti-sticking agent layer is provided on the contacting surfaces of the first noise canceling unit 220 and the second noise canceling unit 320. Specifically, the anti-sticking agent layer may be an oil layer formed by spraying oil onto the surfaces of the first noise canceling unit 220 and the second noise canceling unit 320.

[0038] In some structural forms, the fixing part 210 has a sleeve structure and is easily fitted onto the outer periphery of the sound emitting tube 120. To improve the fitting stability between the fixing part 210 and the sound emitting tube 120, as shown in Figures 3 and 4, an attachment structure 212 is provided on the inner wall of the fixing part 210, and a fixing structure 124 corresponding to the attachment structure 212 is provided on the outer periphery of the sound emitting tube 120, so that when the attachment structure 212 and the fixing structure 124 are fixed relative to each other, a stable connection between the earpiece 200 and the sound emitting tube 120 can be achieved. The attachment structure 212 and the fixing structure 124 may be provided as locking protrusions or locking grooves. The fixing portion 210 may have a circular protrusion (eg, mounting structure 212 ) on its inner wall that fits snugly into a corresponding groove (eg, fixing structure 124 ) around the outer periphery of the sound emitting tube 120 . In this way, the fixed part 210 and the sound emitting tube 120 can be easily removed and replaced using a fastening system.

[0039] Furthermore, a positioning structure 211 may be provided on the inner wall of the fixing part 210, and a position limiting structure 123 may be provided on the outer wall of the sound emission tube 120. The positioning structure 211 is engaged with the position limiting structure 123, preventing the earpiece 200 from rotating on the sound emission tube 120 and improving comfort for the user when worn. The positioning structure 211 and the position limiting structure 123 may also be provided in the form of a locking protrusion or locking groove, and the present application is not limited thereto. The earpiece 200 of the present application may be processed using secondary injection molding. For example, the fixing part 210 may be injection molded first, and then the first noise canceling part 220 may be injection molded on the fixing part 210. The fixing part 210 and the first noise canceling part 220 may be molded and then integrally connected by adhesive bonding, hot melt adhesive connection, or the like.

[0040] 5 , the first noise canceling unit 220 of the present application may include a connection section 222 and a noise canceling section 223, one end of the connection section 222 being connected to the fixed unit 210 and the other end being connected to the noise canceling section 223. At least a portion of the connection section 222 protrudes from the sound output tube 120 and is located on the side away from the main housing 110 along the axial direction E of the sound output tube 120, and this portion of the connection section 222 forms the sound output passage 230, and the end of the noise canceling section 223 away from the second noise canceling unit 320 abuts against the inner wall of the connection section 222. As can be understood, at least a portion of the front end of the earpiece 200 extends into the user's ear canal, and the first noise canceling unit 220 includes the connection section 222 located on the side away from the main housing 110 along the axial direction E of the sound output tube 120, and can be located in the ear canal. Since the material of the earpiece 200 is relatively soft, it is possible to improve the sealing between the user's ear canal and the earpiece 200, avoiding damage to the ear canal by the sound emission tube 120 and improving comfort when inserted into the ear.

[0041] The mounting portion 310 of the wing portion 300 is fitted to the outside of the main housing 110 and can be made of a flexible material to form a protective membrane structure that conforms to the shape of the main housing 110 and, naturally, can be fitted to the main housing 110 due to the ductility of the material. In some structural forms, the second noise canceling portion 320 can form the noise canceling cavity 400 by covering the surface of the user's ear, or can abut against the first noise canceling portion 220 to form the noise canceling cavity 400, thereby allowing the second noise canceling portion 320 to be made of a flexible material. The wing portion 300 of the present application can be integrally molded using materials such as silicone rubber, polyurethane, or epoxy resin.

[0042] When wearing the earphone 10, as the sound emitting tube 120 and the earpiece 200 are inserted into the ear canal, the pressure in the ear canal and the front cavity increases, causing a blocking effect and causing discomfort to the ear. To prevent this, the present application further includes a decompression passage 500 that connects the sound emitting hole 122 to the outside.

[0043] 9, in some structural forms, the decompression passage 500 includes a first passage section 510 and a second passage section 520 that communicate with each other, the first passage section 510 being formed within the wall of the sound emitting tube 120 and communicating with the sound emitting hole 122, and the second passage section 520 being formed within the wall of the main housing 110 and communicating with the outside. The first passage section 510 and the second passage section 520 may be formed by recessing the wall surfaces of the sound emitting tube 120 and the main housing 110, respectively.

[0044] In some connection configurations, the first passage section 510 may have one end communicating with the sound emitting hole 122 and the other end communicating with the noise canceling cavity 400, and the second passage section 520 may have one end communicating with the noise canceling cavity 400 and the other end connected to the outside. In this way, when noise enters the pressure-reducing passage 500, the noise is absorbed and attenuated by the resistance of the noise canceling cavity 400, further improving the noise canceling effect of the present application. Alternatively, the pressure-reducing passage 500 may be an air guide tube, in which mounting grooves are formed in both the wall of the sound emitting tube 120 and the main housing 110, and the air guide tube is fitted into the mounting groove, with one end communicating with the sound emitting hole 122 and the other end communicating with the outside, thereby achieving the functions of air guide and pressure reduction. The present application does not limit the specific form of the pressure-reducing passage 500.

[0045] Similarly, to avoid the pressure in the ear canal and front cavity from increasing during wearing of the earphone 10, causing a blocking effect and causing discomfort to the ear, the present application provides the decompression passage 500 described above. In addition to that , other solutions can be used .fruit In an embodiment, as shown in FIG. 10, a first ventilation passage 224 and a second ventilation passage 225 are provided in the first noise canceling section 220, or the second ventilation passage 225 is provided in the second noise canceling section 320, or the second ventilation passage 225 is defined and formed by the first noise canceling section 220 and the second noise canceling section 320.

[0046] Specifically, when a free end of the first noise canceling part 220 remote from the fixing part 210 abuts against the outer surface of the second noise canceling part 320, a second ventilation passage 225 is formed at the outer peripheral edge of the first noise canceling part 220. Alternatively, when a free end of the second noise canceling part 320 remote from the mounting part 310 abuts against the inner surface of the first noise canceling part 220, a second ventilation passage 225 is formed at the outer peripheral edge of the second noise canceling part 320.

[0047] The first ventilation passage 224 is located closer to the sound output hole 122 than the second ventilation passage 225. When the earphones are worn, the first ventilation passage 224 and the second ventilation passage 225 are respectively located inside and outside the portion of the first noise canceling section 220 that contacts the ear, so that the first ventilation passage 224 connects the user's ear canal with the noise canceling cavity 400, and the second ventilation passage 225 connects the noise canceling cavity 400 with the outside. As can be seen, when the outer surface of the earpiece 200 contacts the ear, it forms a relatively sealed space, and when worn, as the earpiece 200 extends into the ear canal, the gas in the ear canal and the front cavity is pressed, increasing the pressure in the user's ear canal and creating a closure effect. In the present application, the first ventilation passage 224 connects the sealed space to the noise canceling cavity 400, and the second ventilation passage 225 connects the noise canceling cavity 400 to the outside, thus reducing the pressure in the ear canal while wearing the earphones and avoiding discomfort to the user.

[0048] In some implementations, the first ventilation passage 224 is in the form of a through-hole that penetrates the first noise canceling portion 220, and is provided as two through-holes that are symmetrical about the radial direction of the sound output hole 122, thereby achieving relative balance during the decompression process. Naturally, the number of first ventilation passages 224 may be one, three, or the like, and the present application is not limited thereto. The second ventilation passage 225 is a through-groove structure that penetrates the outer peripheral edge of the first noise canceling portion 220, and may be provided in the same number as the first ventilation passage 224. When the second ventilation passage 225 is provided as a through-groove structure, it is easy to process, improves the deformation ability of the earpiece 200, and improves comfort during wearing. Preferably, the present application provides the second ventilation passage 225 and the first ventilation passage 224 offset in the circumferential direction of the earpiece 200. Therefore, if the second ventilation passage 225 and the first ventilation passage 224 are provided too close to each other, this may have the adverse effect of reducing the structural strength of the earpiece 200 where the second ventilation passage 225 and the first ventilation passage 224 are located.
