[0001] This disclosure is a divisional application of Patent Application No. 2025-010691, which is a patent application filed on January 24, 2025, claiming the priority of Chinese Patent Application No. 202420264358.4 titled "Earphone" filed with the China National Intellectual Property Administration on February 1, 2024.

[0002] This application relates to the technical field of earphones, particularly to earphones.

Background Art

[0003] An earphone is a device that can convert an electrical signal into sound. Usually, it is connected to a media player, a mobile phone or other audio devices, and is worn on the ear to transmit sound to the user.

[0004] Earphones can be divided into two types: canal type and ear-cup type. Generally, the earphone body of canal-type earphones has an earpiece, and the earphone blocks noise in a sealed manner. When the earpiece is inserted into the user's ear canal, a sealed space will be formed between the earpiece and the ear canal. However, due to the limited sound insulation effect of the earpiece, external noise can still penetrate the earpiece and enter the ear canal.

Summary of the Invention

Problems to be Solved by the Invention

[0005] This application provides an earphone that can effectively reduce the entry of external noise into the ear canal during the wearing of the earphone.

Means for Solving the Problems

[0006] In a first aspect, the present invention discloses an earphone including an earphone body, an earpiece, and a wing portion, the earphone comprising a body including a main housing and a sound-emitting tube connected to the main housing, and an earpiece including a fixing portion and a first noise-canceling portion connected to each other. The fixing portion is fitted to the outside of the sound-emitting tube, and the first noise-canceling portion is provided surrounding the outer circumference of the fixing portion. The earphone further comprises a wing portion including a second noise-canceling portion. The second noise-canceling portion is provided surrounding the outer circumference of the main housing. A cavity is formed between the first noise-canceling portion and the second noise-canceling portion, and the cavity blocks ambient noise.

[0007] The beneficial effect of this invention is that a first noise-canceling section is provided on the earpiece, and a second noise-canceling section is provided on the wing section. The earpiece is connected to the sound-emitting tube, the first noise-canceling section is provided surrounding the outer circumference of the sound-emitting tube, the wing section is connected to the main housing, and the second noise-canceling section is provided surrounding the outer circumference of the main housing. As a result, the first and second noise-canceling sections can block multiple layers of noise entering the user's ear. Furthermore, because the earpiece and wing section are independent components, the user can select a size appropriate for their ear canal and freely remove and replace these components, thereby improving the comfort of wearing the earphones.

[0014] Figure 1 shows a schematic configuration diagram of an earphone 10 according to one embodiment of the present invention. The earphone 10 may be a wired or wireless in-ear earphone 10 and may be connected to a device such as a mobile phone, computer, MP3 player, or wearable audio device. To the best of our understanding, without departing from the concept of the present invention, the earphone 10 may be designed in other forms, such as an over-ear earphone 10.

[0015] The earphone 10 may include an earphone body 100, an earpiece 200 (e.g., an earpiece), and a wing portion 300 (e.g., an ear wing portion). The earpiece 200 and the wing portion 300 are detachably 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. The sound emitting tube 120 is connected to the main housing 110, and the main housing 110 and the sound emitting tube 120 may be integrally formed by injection molding, or may be provided as a separate structure fixedly connected by a fastening or connecting member or the like. The sound emitting tube 120 has a sound passage, and a sound emitting hole 122 communicating with the sound passage is provided at an end of the sound emitting tube 120. A housing cavity may be formed in the main housing 110, and the sound passage communicates with the housing cavity.

[0017] The earphone 10 may further include an electronic control module 700 (such as a controller, a control assembly), a speaker 600, and the like. The speaker 600 is provided in the sound emitting tube 120 and transmits sound to the outside through the sound emitting tube 120, and the electronic control module 700 is provided in the housing cavity. The electronic control module 700 may include a control board, a battery, and the like. The axial direction of the sound emitting tube 120 and the extending direction of the main housing 110 may be provided at an angle. The main housing 110 may be in a flat form, and the electronic control module 70 is arranged as a flat block structure or a box structure so as to conform to the shape of the main housing 110. When provided in this way, the overall structure of the earphone 10 becomes relatively small, the earphone 10 is easily worn at the position of the ear, does not protrude excessively outside the ear, and is particularly suitable for use during sleep.

[0018] The earpiece 200 has a sound emitting passage 230 and includes a fixing portion 210 and a first noise canceling portion 220 (such as a deformable layer or panel, a shape memory foam layer or panel) connected to each other. When the fixing portion 210 is fitted to the sound emitting tube 120, the sound emitting passage 230 communicates with the sound emitting hole 122, and the first noise canceling portion 220 is provided to surround the outer periphery of the sound emitting 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 the sound reproduced by the speaker 600 may sequentially pass through the sound passage, the sound emitting hole 122, and the sound emitting passage 230 and be transmitted to the ear canal.

[0019] The wing part 300 includes an attachment part 310 and a second noise canceling part 320. The attachment part 310 is connected to the second noise canceling part 320. The attachment part 310 is connected to the main housing 110, and the second noise canceling part 320 is provided to surround the outer periphery of the main housing 110. Further, the wing part 300 includes a support part 330 located at an end of the attachment part 310 away from the second noise canceling part 320. In other words, in the circumferential direction of the earphone 10, a support part 330 protruding outward is provided at an end of the wing part 300 away from the attachment part 310. The support part 330 is arranged to abut against the auricle when the wing part 300 is located in the concha cavity. The support part 330 can fix the earphone 10 to the ear and provide further stability and comfort. By inserting the wing part 300 into the auricle during use, the earphone 10 can be better adhered to the ear, avoiding the earphone 10 from falling or swaying during exercise or other activities.

[0020] In the present application, as shown in FIG. 3, the first noise canceling part 220 is provided on the earpiece 200, while the second noise canceling part 320 is provided on the wing part 300. A noise canceling cavity 400 is formed (for example, formed) between the first noise canceling part 220 and the second noise canceling part 320. The noise canceling cavity 400 blocks environmental noise entering the user's ear canal. Since the earpiece 200 and the wing part 300 are independent members, they can be freely removed and exchanged. The user can select a size suitable based on the size of their ear canal, thus improving the wearing comfort of the earphone 10.

[0021] In some embodiments, the first noise-canceling section 220 abuts against the second noise-canceling section 320, and the outer walls of the first noise-canceling section 220, the second noise-canceling section 320, and the earphone body 100 surround the noise-canceling cavity 400. To make it clear, the abutment between the first noise-canceling section 220 and the second noise-canceling section 320 may be such that the free end of the first noise-canceling section 220 away from the fixing section 210 abuts against the outer surface of the second noise-canceling section 320, or that the free end of the second noise-canceling section 320 away from the mounting section 310 abuts against the inner surface of the first noise-canceling section 220. Hereinafter, the present application does not limit itself to any specific form in which the first noise-canceling section 220 and the second noise-canceling section 320 abut against each other.

[0022] In natural conditions, the first noise-canceling section 220 and the second noise-canceling section 320 may be in contact with each other (for example, in a state of contact with each other). When the earphones are worn, if the first noise-canceling section 220 and the second noise-canceling section are not in contact, the first noise-canceling section 220 will be deformed by being pressed against the inner wall of the ear canal, and the first noise-canceling section will come into contact with the second noise-canceling section 320, forming a noise-canceling cavity 400. For example, there may be a gap between the first noise-canceling section 220 and the second noise-canceling section 320. When a user wears the earphones 10 of the present invention, some external noise is blocked by the second noise-canceling section 320, and some enters the noise-canceling cavity 400. The noise in this section is absorbed and attenuated by resistance within the noise-canceling cavity 400, and is also twisted, reducing its energy and frequency characteristics, making it difficult for it to pass through the first noise-canceling section 220 and enter the user's ear canal.

[0023] The noise-canceling cavity 400 may be surrounded by the outer wall of the first noise-canceling section 220, the second noise-canceling section 320, and the sound-emitting tube 120, or it may be surrounded by the outer wall of the first noise-canceling section 220, the second noise-canceling section 320, the sound-emitting tube 120, and a part of the outer wall of the main housing 110, or it 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, the mounting section 310 abuts against the fixed section 210, and the free end of the first noise-canceling section 220 (for example, the end away from the fixed section 210) abuts against the free end of the second noise-canceling section 320 (i.e., the end away from the mounting section 310), so that the first noise-canceling section 220 and the second noise-canceling section 320 can surround and / or form the noise-canceling cavity 400.

[0024] To improve the stability of contact between the first noise-canceling section 220 and the second noise-canceling section 320, the outer end surface 221 of the first noise-canceling section 220, away from the fixing section 210, does not extend beyond the outer end of the second noise-canceling section 320, away from the mounting section 310. For example, in a natural state, the outer end surface 221 of the first noise-canceling section 220, away from the fixing section 210, contacts the second noise-canceling section 320. In a worn state, even if the outer end surface 221 of the first noise-canceling section 220, away from the fixing section 210, is compressed and deformed by some pressure when the first noise-canceling section 220 is inserted into the ear canal, the outer end surface 221 of the first noise-canceling section 220, away from the fixing section 210, always contacts the second noise-canceling section 320, thereby effectively improving the sealing performance of the noise-canceling cavity 400.

[0025] To make it clear, the noise-canceling cavity 400 is used to reduce, absorb, and attenuate noise, and therefore, by providing the noise-canceling cavity 400 so as to surround the outer circumference of the sound-emitting tube 120, noise from all directions can be blocked, further improving the noise-canceling effect of the earphone 10. In any earphone 10 described above or below, the noise-canceling cavity 400 can be provided so as to surround the outer circumference of the sound-emitting tube 120. In some structural configurations, the noise-canceling cavity 400 may be provided only in the direction in which noise is more likely to enter.

[0026] As shown in Figure 2, the outer diameters of both the first noise-canceling section 220 and the second noise-canceling section 320 are designed to decrease in the direction away from the main housing 110 along the axial direction E of the sound-emitting tube 120. Furthermore, the outer diameter of the first noise-canceling section 220 is designed to decrease 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 the fit more comfortable. However, during wear, the first noise-canceling section 220 may be compressed and deformed by pressure from the ear canal. In this invention, the outer diameter of the second noise-canceling section 320 is also provided to gradually decrease in the direction away from the main housing 110 along the axial direction E of the sound-emitting tube 120. This reduces the support force of the second noise-canceling section 320 on the first noise-canceling section 220 when the first noise-canceling section 220 comes into contact with the second noise-canceling section 320, making the first noise-canceling section 220 less likely to deform in the ear canal and avoiding a reduction in comfort during wear. Furthermore, this configuration improves the sealing performance of the noise-canceling cavity 400. In some other structural configurations, the second noise-canceling section 320 may be arranged horizontally in the axial direction of the sound-emitting tube 120. In this case, when the first noise-canceling section 220 and the second noise-canceling section 320 are connected to each other (mounted relative to each other), they form a triangular support state, and the high sealing performance of the noise-canceling cavity 400 can be maintained.

[0027] In some embodiments of the present invention, as shown in Figure 11, the second noise-canceling section 320 is located on the side of the first noise-canceling section 220 facing the main housing 110, with its intermediate portion projecting toward the sound-emitting hole 122. With this configuration, the free end of the second noise-canceling section 320 tends to deform inward, and because the intermediate portion is provided to protrude, it is also possible to provide outward deformation elasticity relative to the free end of the second noise-canceling section 320, and with this configuration, the second noise-canceling section 320 has high flexibility. Thus, when the first noise-canceling section 220 is pressed by the ear during the user's fitting process, the second noise-canceling section 320 deforms linearly based on the force applied, improving comfort and sealing when the user is wearing the headphones.

[0028] In some embodiments, the hardness of the second noise-canceling section 320 is greater than that of the first noise-canceling section 220. More specifically, since the first noise-canceling section 220 abuts against the second noise-canceling section 320 to form a sealed noise-canceling cavity 400, the hardness of the second noise-canceling section 320 may be slightly greater than that of the first noise-canceling section 220 to ensure a tight seal between the first and second noise-canceling sections 220 and 320 when worn. In this way, the second noise-canceling section 320 has a certain support capacity against the first noise-canceling section 220, thereby increasing the sealing effect of the noise-canceling cavity 400 and improving the noise-canceling effect.

[0029] Furthermore, the first noise-canceling section 220 may extend from the side of the sound-emitting tube 120 away from the main housing 110 toward the side of the sound-emitting tube 120 closer to the main housing 110, and the second noise-canceling section 320 may extend from the connection point between the sound-emitting tube 120 and the main housing 110 toward the side of the main housing away from the sound-emitting tube 120. This allows for the formation of a noise-canceling cavity 400 on the outside of the sound-emitting tube 120, with a radial length slightly larger than the radial length of the sound-emitting tube 120. This also allows for a relatively large volume of the noise-canceling cavity 400, effectively increasing the area of ​​the sound-emitting tube 120 surrounded by the noise-canceling cavity 400, thereby improving the noise-canceling effect of the present invention.

[0030] To further improve the sealing performance of the noise-canceling cavity 400 and enhance the noise-canceling effect, embodiments of the present invention provide several structural configurations as follows.

[0031] As shown in Figure 6, the outer end surface 221 (e.g., the lower end) of the first noise-canceling section 220, away from the fixed portion 210, conforms to the contour of the side surface of the second noise-canceling section 320 facing the first noise-canceling section 220. In contrast to a configuration where one contact point on the outer end surface 221 of the first noise-canceling section 220, away from the fixed portion 210, abuts against the side surface of the second noise-canceling section 320 facing the first noise-canceling section 220, the present invention increases the contact area between the first noise-canceling section 220 and the second noise-canceling section 320, thereby improving the contact stability between the first noise-canceling section 220 and the second noise-canceling section 320 and further improving the sealing performance of the noise-canceling section.

[0032] As shown in Figure 7, a groove 321 is formed on the side surface of the second noise-canceling section 320 facing the first noise-canceling section 220. When the outer end surface 221 of the first noise-canceling section 220, away from the fixing section 210, contacts the groove 321, the first noise-canceling section 220 and the groove 321 have at least two contact points. As illustrated in Figure 7, the first noise-canceling section 220 and the groove 321 have three contact points. The outer end surface 221 of the first noise-canceling section 220 abuts 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 section 220 facing the sound-emitting tube 120 abuts against the apex of the side wall of the groove 321. Thus, by having multiple contact points between the first noise-canceling section 220 and the second noise-canceling section 320, multiple sealing lines are formed on the outer circumference of the noise-canceling cavity 400, further improving the sealing performance and noise-canceling effect of the noise-canceling cavity 400. In addition, the groove 321 ensures that the first noise-canceling section 220 stably abuts against the second noise-canceling section 320, further improving the sealing performance of the noise-canceling cavity 400.

[0033] As shown in Figure 8, a projection 322 is formed on the side of the second noise-canceling section 320 facing the first noise-canceling section 220, and even in this case, the first noise-canceling section 220 and the second noise-canceling section 320 have two contact points. Specifically, the outer end surface 221 of the first noise-canceling section 220 abuts against the second noise-canceling section 320, and the side of the first noise-canceling section 220 facing the sound-emitting tube 120 abuts against the projection 322. In this way, the first noise-canceling section 220 and the second noise-canceling section 320 have two contact points, which forms two sealing lines on the outer circumference of the noise-canceling cavity 400, thereby improving the noise-canceling effect. Alternatively, the projection 322 is provided on the side of the first noise-canceling section 220 facing the second noise-canceling section 320. In this case, both the outer end surface 221 of the first noise-canceling section 220 and the projection 322 come into contact with the second noise-canceling section 320.

[0034] In addition, 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 this application, the present application provides another embodiment in which, when worn, the first noise-canceling section 220 and the second noise-canceling section 320 each contact different positions on the user's ear. Specifically, when worn, the first noise-canceling section 220 can be in close contact with the user's ear canal, and the second noise-canceling section 320 can be in close contact with the surface of the user's ear. In this case, the first noise-canceling section 220, the second noise-canceling section 320, the user's ear, and the outer wall of the earphone body 100 surround the noise-canceling cavity 400.

[0036] To ensure understanding, the first noise-canceling section 220 is made of a relatively soft material that makes tight contact with the ear canal, improving comfort when inserted into the ear, and also possesses excellent deformation ability, effectively conforming to the user's ear canal and blocking out ambient noise. The fixing section 210 is connected to the sound-emitting tube 120 and is made of a hard material to ensure stability of attachment and connection, and to prevent the earpiece 200 from falling into the ear canal when the sound-emitting tube 120 is inserted into the ear canal, thus maintaining a certain stability and shape. As described above, materials such as silicone rubber, polyurethane, or epoxy resin with different hardness levels can be used. Hereinafter, this application does not specifically limit the materials of the first noise-canceling section 220 and the fixing section 210.

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

[0038] In some structural configurations, the fixing part 210 is a sleeve structure that is easily fitted onto the outer circumference 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, a mounting structure 212 is provided on the inner wall of the fixing part 210, and a fixing structure 124 corresponding to the mounting structure 212 is provided on the outer circumference of the sound-emitting tube 120. When the mounting structure 212 and the fixing structure 124 are relatively fixed, the earpiece 200 and the sound-emitting tube 120 can be stably connected. The mounting structure 212 and the fixing structure 124 may be provided as locking projections or locking grooves. The fixing part 210 may have a circular projection (e.g., mounting structure 212) on its inner wall that fits snugly into a corresponding groove (e.g., fixing structure 124) surrounding the outer circumference of the sound-emitting tube 120. In this way, the fixing part 210 and the sound-emitting tube 120 can be easily removed and replaced using a locking mechanism.

[0039] Furthermore, a positioning structure 211 may be provided on the inner wall of the fixed part 210, and a position limiting structure 123 may be provided on the outer wall of the sound-emitting tube 120. The positioning structure 211 is engaged with the position limiting structure 123, preventing the earpiece 200 from rotating on the sound-emitting tube 120 and improving user comfort during wear. The positioning structure 211 and the position limiting structure 123 may similarly be provided in the form of locking projections or locking grooves, and this application is not limited thereto. Regarding the manufacturing method of the earpiece 200 of this application, secondary injection molding may be used. For example, the fixed part 210 may be injection-molded first, then the first noise-canceling part 220 may be injection-molded onto the fixed part 210. Alternatively, the fixed part 210 and the first noise-canceling part 220 may be molded separately and then integrally connected by adhesive bonding, hot-melt adhesive bonding, or other methods.

[0040] As shown in Figure 5, the first noise-canceling section 220 of the present invention may include a connecting section 222 and a noise-canceling section 223, the connecting section 222 having one end connected to a fixed section 210 and the other end connected to the noise-canceling section 223. At least a portion of the connecting section 222 protrudes from the sound-emitting tube 120 and is located on the side away from the main housing 110 along the axial E of the sound-emitting tube 120, and the portion of the connecting section 222 forms a sound-emitting passage 230, and the end of the noise-canceling section 223 away from the second noise-canceling section 320 abuts against the inner wall of the connecting section 222. To understand that at least a portion of the front end of the earpiece 200 extends into the user's ear canal, the first noise-canceling section 220 may include a connecting section 222 located on the side away from the main housing 110 along the axial E of the sound-emitting tube 120 and be located in the ear canal. Because the material of the ear tip 200 is relatively soft, it can improve the seal between the user's ear canal and the ear tip 200, which can prevent damage to the ear canal from the sound discharge tube 120 and improve 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 manufactured from a soft material to conform 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 configurations, the second noise-canceling portion 320 may form a noise-canceling cavity 400 by covering the surface of the user's ear, or it may form a noise-canceling cavity 400 by abutting against the first noise-canceling portion 220, thereby allowing the second noise-canceling portion 320 to be manufactured from a soft material. The wing portion 300 of the present invention can be integrally molded using a material such as silicone rubber, polyurethane, or epoxy resin.

[0042] When the earphone 10 is worn, as the sound-emitting tube 120 and earpiece 200 are inserted into the ear canal, the pressure in the ear canal and the front cavity increases, creating a occluding effect. To prevent discomfort to the ear, the present invention further includes a depressurizing passage 500 that connects the sound-emitting hole 122 to the outside.

[0043] As shown in Figure 9, in some structural configurations, 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-releasing pipe 120 and communicating with the sound-releasing 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 recesses in the wall surface of the sound-releasing pipe 120 and the wall surface of the main housing 110, respectively.

[0044] In some connection configurations, the first passage section 510 may have one end communicating with the sound vent 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 decompression passage 500, this noise is absorbed and attenuated by the resistance of the noise-canceling cavity 400, further improving the noise-canceling effect of the present invention. The decompression passage 500 may also be an air conduit, and mounting grooves are provided in both the wall of the sound vent 120 and the main housing 110. The air conduit is fitted into the mounting groove, with one end communicating with the sound vent 122 and the other end communicating with the outside, thereby realizing air conduit and decompression functions. Hereinafter, the present invention does not limit the specific form of the decompression passage 500.

[0045] Similarly, in order to avoid causing discomfort to the ear by increasing pressure in the ear canal and front cavity and creating a clotting effect while the earphone 10 is being worn, the present invention may use other solutions in addition to providing the decompression passage 500 as described above. In embodiments, as shown in Figure 10, the first noise-canceling section 220 is provided with a first ventilation passage 224 and a second ventilation passage 225, 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 the free end of the first noise-canceling section 220, away from the fixed section 210, contacts the outer surface of the second noise-canceling section 320, a second ventilation passage 225 is formed on the outer peripheral edge of the first noise-canceling section 220. Alternatively, when the free end of the second noise-canceling section 320, away from the mounting section 310, contacts the inner surface of the first noise-canceling section 220, a second ventilation passage 225 is formed on the outer peripheral edge of the second noise-canceling section 320.

[0047] The first ventilation passage 224 is positioned closer to the sound vent 122 than the second ventilation passage 225. When worn, the first ventilation passage 224 and the second ventilation passage 225 are located on the inside and outside of the part of the first noise-canceling section 220 that contacts the ear, respectively. The first ventilation passage 224 connects the user's ear canal to the noise-canceling cavity 400, and the second ventilation passage 225 connects the noise-canceling cavity 400 to the outside. To understand this, when the outer surface of the earpiece 200 contacts the ear, it forms a relatively sealed space. When worn, as the earpiece 200 extends into the ear canal, the gas in the ear canal and front cavity is compressed, increasing the pressure in the user's ear canal and creating a sealing effect. In this invention, the first ventilation passage 224 connects the sealed space with the noise-canceling cavity 400, and the second ventilation passage 225 connects the noise-canceling cavity 400 with the outside, thereby reducing the pressure in the ear canal while wearing the device and avoiding user discomfort.

[0048] In some realizations, the first ventilation passage 224 is in the form of a through-hole provided through the first noise-canceling section 220, and consists of two passages provided symmetrically with respect to the radial direction of the sound-emitting hole 122, thus achieving relative equilibrium during the depressurization process. Naturally, the number of first ventilation passages 224 may be one, three, or the like, and this 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 section 220, and may be provided in the same number as the first ventilation passages 224. When the second ventilation passage 225 is provided as a through-groove structure, it has the advantage of being easy to process, improving the deformation capability of the earpiece 200 and improving comfort during wear. Preferably, in this application, the second ventilation passage 225 and the first ventilation passage 224 may be provided offset in the circumferential direction of the earpiece 200, so that if they are too close together, it will have the adverse effect of reducing the structural strength of the earpiece 200 where they are located.
