Abstract
Description
Technical Field
[0001] This application relates to the field of headphone technology, and more particularly to an earplug and a headphone. Background Technology
[0002] Headphones typically consist of a main body and soft ear tips that fit around it. Soft ear tips have good flexibility and elasticity, and when the ear tips are inserted into the user's ear canal, they can effectively conform to the inner wall of the ear canal, thereby achieving a good seal in the ear canal.
[0003] However, users' ear canals may continuously secrete oil, which gradually adheres to the surface of the earplugs, disrupting the original good friction and fit between the earplugs and the ear canal, resulting in a significant decrease in the stability of the headphones within the ear canal. In addition, during exercise, the user's body is in a dynamic state, and the combined effects of head shaking, ear vibration, and sweat secretion make it difficult to maintain a secure fit even if the earplugs have a certain degree of fit, and the headphones are prone to falling out of the ear canal. Utility Model Content
[0004] This application provides an earplug that can improve the stability of headphones in the ear canal and reduce the probability that headphones will easily fall out of the ear canal.
[0005] Firstly, an earplug is provided, comprising:
[0006] Mounting part, the mounting part being used to mount to the body of the earphone;
[0007] A flexible body is provided around the mounting portion, at least a portion of the flexible body is spaced apart from the mounting portion to form a void, and at least a portion of the flexible body can be inserted into the user's ear canal;
[0008] The outer surface of the flexible body has a first textured pattern, which provides frictional resistance opposite to the direction of movement as the earplug moves along the ear canal.
[0009] The earplug provided in this application embodiment has a first textured pattern on the outer surface of the flexible body. The first textured pattern can increase the roughness of the outer surface of the flexible body, thereby providing frictional resistance opposite to the direction of movement when the earplug moves along the ear canal, reducing the probability of the earphone easily falling out of the ear canal and improving the wearing stability of the earphone. At least a portion of the flexible body is spaced apart from the mounting part to form a void. When the flexible body is squeezed and deformed by the user's ear canal, the void can accommodate the deformed flexible body. In this way, the deformation of the mounting part can be reduced or even prevented from deforming. This ensures the connection stability between the earplug and the earphone body, further ensuring the wearing stability of the earphone.
[0010] In one possible implementation, the first texture pattern is a concave-convex structure disposed on the outer surface of the flexible body, the concave-convex structure being used to provide frictional resistance as the earplug moves outward along the ear canal.
[0011] In this embodiment, the first texture pattern can only increase the frictional resistance when the earbud moves outward along the ear canal, without increasing the frictional resistance when the earbud enters the ear canal. In this way, the difficulty of wearing the headphones can be reduced, which helps the user to put the headphones in place and ensures the stability of the headphones.
[0012] In one possible implementation, the first texture pattern includes one or more first recesses recessed from the outer surface of the flexible body.
[0013] The first recess increases the roughness of the flexible body's outer surface, thereby increasing the friction between the flexible body and the ear canal, reducing the probability of the earphones falling out of the ear canal, and improving the earphone's wearing stability. The first texture pattern does not form a structure protruding from the flexible body's outer surface, thus not affecting the earbud's fit; that is, it does not increase the frictional resistance when the earbud enters the ear canal. This reduces the difficulty of wearing the earphones, helping users to put them in place and ensuring wearing stability.
[0014] In this embodiment, the outer surface of the flexible body is arc-shaped, and the first concave part can form a "barb" structure on the outer side of the flexible body. When the earplug tends to move outward along the ear canal, the "barb" structure can abut against the inner wall of the ear canal to increase the resistance to the movement of the earplug.
[0015] In one possible implementation, the first recess is annular and surrounds the mounting portion.
[0016] The first recess is set as an annular shape and surrounds the mounting part. The first recess is provided in the circumference of the flexible body. In this way, the frictional resistance of the flexible body when it moves outward along the ear canal can be increased at all points in the circumference of the flexible body, thereby further improving the wearing stability of the headphones.
[0017] Of course, in other embodiments, the first recess may be strip-shaped, and the length of the first recess may extend along the circumferential direction of the flexible body. In this embodiment, multiple first recesses may also be provided, with at least two first recesses arranged along the circumferential direction of the flexible body, and the ends of two adjacent first recesses facing each other and spaced apart. In this way, the frictional resistance of the flexible body moving outward along the ear canal can be increased at all points along the circumference of the flexible body by increasing the number of first recesses or increasing the length of the first recesses.
[0018] In one possible implementation, a plurality of the first recesses are arranged sequentially along the direction from the front end of the flexible body toward the rear end of the flexible body.
[0019] The first recess is provided in multiple ways, and the multiple first recesses are arranged sequentially along the direction from the front end of the flexible body to the rear end of the flexible body. By increasing the number of first recesses, the frictional resistance when the flexible body moves outward along the ear canal can be increased, thereby enhancing the wearing stability of the headphones.
[0020] In one possible implementation, the first recess has a first surface facing the rear end of the flexible body, the first surface projecting onto the outer surface of the flexible body in a straight line; or,
[0021] The first surface has a wavy shape when projected onto the outer surface of the flexible body.
[0022] Setting the orthographic projection of the first surface onto the outer surface of the flexible body to be a straight line simplifies the structure of the first recess and facilitates its processing, thus helping to reduce the processing cost of the earplug.
[0023] Setting the orthographic projection of the first surface onto the outer surface of the flexible body to be wavy can further increase the roughness of the outer surface of the flexible body. This can further increase the difficulty of the earbud being removed from the ear canal, thus helping to further improve the stability of the headphones when worn.
[0024] In some embodiments, the first recess has a second surface opposite to the first surface, which can be smoothly connected to the outer surface of the flexible body, thereby reducing the resistance between the earbud and the ear canal when wearing headphones.
[0025] In one possible implementation, the recessed areas of two adjacent wavy first surfaces are staggered.
[0026] By alternating the concave areas of two adjacent wavy first surfaces, the roughness of the outer surface of the flexible body can be balanced. This balances the friction between the outer surface of the flexible body and the ear canal, which helps to further improve the stability of wearing the headphones.
[0027] In this embodiment of the application, the staggered arrangement of the recessed areas of two adjacent wavy first surfaces can make the outer surface of the flexible body present a fish scale pattern as a whole.
[0028] In one possible implementation, a first protrusion is provided in the recessed area of the wavy first surface.
[0029] By setting a first protrusion in the recessed area of the first wavy surface, that is, by using the space in the recessed area of the first wavy surface to set a first protrusion, the roughness of the outer surface of the flexible body can be further increased. In this way, the frictional resistance when the flexible body moves outward along the ear canal can be further increased, thereby enhancing the wearing stability of the headphones.
[0030] In one possible implementation, the first textured pattern includes a plurality of second protrusions formed on the flexible body, the end faces of which are used to adhere to the inner wall of the ear canal.
[0031] During the wearing of the headphones, the end face of the second protrusion is pressed to fit against the inner wall of the user's ear canal. Under the pressure, air flows out from between the end face of the second protrusion and the inner wall of the user's ear canal, so that a negative pressure can be formed between the end face of the second protrusion and the inner wall of the user's ear canal. At this time, the second protrusion can adhere to the inner wall of the ear canal like a suction cup. When the flexible body moves towards the outside of the ear canal, the force between the end face of the second protrusion and the inner wall of the ear canal can resist the movement of the flexible body, thus improving the wearing stability of the headphones.
[0032] In one possible implementation, the orthographic projection pattern of the second protrusion on the outer surface of the flexible body is elliptical, circular, annular, triangular, quadrilateral, pentagonal, or hexagonal.
[0033] The orthographic projection pattern of the second protrusion on the outer surface of the flexible body is elliptical, circular, annular, triangular, quadrilateral, or pentagonal. The outer surface contour of the second protrusion can be diversified. In this way, the surface of the second protrusion can fit more closely to the inner wall of the ear canal, thereby increasing the frictional resistance when the flexible body moves towards the outside of the ear canal and improving the wearing stability of the headphones.
[0034] Of course, the orthographic projection pattern of the second protrusion on the outer surface of the flexible body can also be hexagonal in a certain region and circular in another region. In other embodiments, the orthographic projection pattern of the second protrusion on the outer surface of the flexible body can also be polygonal or irregular. This application does not impose any limitations on these embodiments.
[0035] In one possible implementation, the first texture pattern includes a second recess recessed from the outer surface of the flexible body, the orthographic projection pattern of the second recess on the outer surface of the flexible body being mesh-like, and the enclosing area of the second recess forming a plurality of second protrusions.
[0036] The second concave portion has a mesh-like pattern projected onto the outer surface of the flexible body, thereby enclosing and forming multiple second convex portions. In this way, the second convex portions protrude relative to the second concave portions, and the end face of the second convex portion is the outer surface of the flexible body. During the wearing of headphones, the wearing resistance generated by the second convex portions can be reduced or even eliminated, thus making it easier to put the headphones in place.
[0037] In one possible implementation, along the direction in which the flexible body is inserted into the ear canal, at least the depth of the portion of the second recess located in the front end region of the flexible body is less than the depth of the portion of the second recess located in the middle region of the flexible body.
[0038] Along the direction in which the flexible body is inserted into the ear canal, at least the depth of the portion of the second recess located in the front end region of the flexible body is less than the depth of the portion of the second recess located in the middle region of the flexible body. The roughness of the end region of the outer surface of the flexible body is less than the roughness of the middle region of the outer surface of the flexible body. When the user wears the headphones, the roughness of the portion of the front end region of the flexible body is smaller, making it easier to put the headphones in place. When the headphones are in place, the portion of the middle region of the flexible body can abut against the ear canal. When the flexible body moves toward the outside of the ear canal, the portion of the middle region of the flexible body can provide greater frictional resistance, thus improving the wearing stability of the headphones.
[0039] In one possible implementation, the flexible body is further provided with a second texture pattern that matches the first texture pattern on the side near the mounting portion.
[0040] A second textured pattern matching the first textured pattern is also provided on the side of the flexible body near the mounting part, making the thickness of the flexible body uniform. In this way, the second textured pattern can form a protrusion in the recessed area of the first textured pattern. The uniform thickness of the flexible body can ensure the strength of the flexible body and reduce the possibility of damage due to insufficient thickness, that is, it can reduce the impact of the first textured pattern on the strength of the flexible body.
[0041] In this embodiment, the first texture pattern is a first recessed portion recessed from the outer surface of the flexible body. The first recessed portion is annular and surrounds the mounting portion. Thus, the second texture pattern can be correspondingly set as a third protruding portion protruding from the side of the flexible body near the mounting portion. The third protruding portion is annular and surrounds the mounting portion.
[0042] In this embodiment, a second texture pattern matching the first texture pattern is also provided on the side of the flexible body near the mounting part, so that the thickness of the flexible body is uniform. The first texture pattern includes a second recess that is recessed from the outer surface of the flexible body. The orthographic projection pattern of the second recess on the outer surface of the flexible body is a mesh. Thus, the second texture pattern can be correspondingly set as a fourth protrusion that is protruded from the side of the flexible body near the mounting part. The orthographic projection pattern of the fourth protrusion on the outer surface of the flexible body is a mesh.
[0043] In other embodiments, the side of the flexible body near the mounting portion may not have a second textured pattern, that is, the side of the flexible body near the mounting portion is smoothly provided. This can reduce the processing difficulty of the flexible body and help reduce the cost of the earphone.
[0044] In one possible implementation, the depth of the first texture pattern is less than or equal to the thickness of the flexible body.
[0045] The depth of the first texture pattern is set to be less than or equal to the thickness of the flexible body. When the depth of the first texture pattern is less than the thickness of the flexible body, the flexible body will not form holes due to the first texture pattern, thus ensuring that the flexible body has the corresponding strength. When the depth of the first texture pattern is equal to the thickness of the flexible body, the first texture pattern can form holes in the flexible body, making the shape of the flexible body more diverse. In addition, when the flexible body is equipped with both the first texture pattern and the second texture pattern, even if the depth of the first texture pattern is equal to the thickness of the flexible body, the flexible body will still not form holes because the second texture pattern will make up for the part of the flexible body that is thinned by the first texture pattern, so that the thickness of the flexible body is uniform throughout.
[0046] In this embodiment of the application, the first texture pattern is a first recess formed by recessing from the outer surface of the flexible body, and the depth of the first recess is less than or equal to the thickness of the flexible body.
[0047] In some embodiments, the depth of the second recess is less than or equal to the thickness of the flexible body. When the depth of the second recess varies in different areas, the maximum depth of the second recess is less than or equal to the thickness of the flexible body. For example, when the depth of the second recess is less than the thickness of the flexible body, the flexible body will not form a hole due to the second recess, thus ensuring that the flexible body has the corresponding strength; when the depth of the second recess is equal to the thickness of the flexible body, the second recess can form a hole in the flexible body, allowing for diverse shapes of the flexible body; furthermore, when the flexible body is simultaneously provided with a first texture pattern and a second texture pattern, even if the depth of the second recess is equal to the thickness of the flexible body, the flexible body will still not form a hole, because the second texture pattern will compensate for the portion of the flexible body that is thinned by the second recess, so that the thickness of the flexible body is uniform throughout.
[0048] Secondly, an earphone is provided, including a body and the aforementioned earplugs, the earplugs being mounted on the body.
[0049] The earphone provided in this application embodiment has a first textured pattern on the outer surface of the flexible body of its earbud. The first textured pattern can increase the roughness of the outer surface of the flexible body, thereby increasing the frictional resistance when the earbud moves outward along the ear canal, reducing the probability that the earphone will easily fall out of the ear canal, and improving the wearing stability of the earphone.

[0070] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0071] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0072] In the description of this application, it should be understood that the terms "upper", "lower", "side", "front", "rear", etc., indicate the orientation or positional relationship based on the installation orientation or positional relationship, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0073] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "a plurality of" means two or more.
[0074] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0075] In today's audio device market, earphones that insert into the user's ear, and true wireless stereo (TWS) earphones, are highly favored by consumers due to their portability and excellent audio experience. These earphones typically consist of a main body and soft ear tips that fit it. Soft ear tips, with their good flexibility and elasticity, have a significant advantage in adapting to different ear canal shapes. When the ear tips enter the user's ear canal, they effectively conform to the inner wall of the ear canal, thus achieving a good seal. This seal is crucial for creating the best sound experience; it reduces interference from external noise, allowing sound to propagate in a relatively enclosed space within the ear canal, thereby improving audio clarity, stereo effect, and sound quality.
[0076] However, in actual use, these headphones still face some problems that urgently need to be solved. For example, for users with oily ears, the ear canal continuously secretes a lot of oil, which gradually adheres to the surface of the earbuds. The accumulated oil will disrupt the original good friction and fit between the earbuds and the ear canal, resulting in a significant decrease in the stability of the headphones within the ear canal. In addition, during exercise, the user's body is in a dynamic state. The combined effects of head shaking, ear vibration, and sweat secretion pose a serious challenge to the original stability of the headphones. Even if the earbuds have a certain fit, it is still difficult to maintain a secure fit during vigorous exercise, and the headphones are prone to falling out of the ear canal. Once the headphones fall out, it will not only interrupt the audio content the user is enjoying, but may also damage the headphones, causing a lot of inconvenience and financial loss to the user.
[0077] Based on this, embodiments of this application provide an earplug and an earphone that can improve the stability of the earphone in the ear canal and reduce the probability that the earphone will easily fall out of the ear canal.
[0078] The earphone provided in this application embodiment is an in-ear earphone, which includes a body and an earbud installed on the body. The body may be equipped with a memory, a processor, a wireless communication module, a speaker, a microphone, a battery, and various sensors. The earbud can be inserted into the user's ear canal and effectively fit the inner wall of the ear canal.
[0079] Figure 1 This is a schematic diagram of the structure of an earplug 1000 provided in one embodiment of this application; Figure 2 for Figure 1The diagram shows a cross-sectional view of the earplug 1000. (Refer to...) Figure 1 and Figure 2 The earplug 1000 provided in this application embodiment includes a mounting portion 200 and a flexible body 100. The mounting portion 200 is used to mount on the body of an earphone. The flexible body 100 is disposed around the mounting portion 200, and at least a portion of the flexible body 100 is spaced apart from the mounting portion 200 to form a void 500. At least a portion of the flexible body 100 can be inserted into the user's ear canal. The outer surface of the flexible body 100 has a first texture pattern 1, which is used to provide frictional resistance opposite to the direction of movement when the earplug 1000 moves along the ear canal.
[0080] It should be noted that the mounting part 200 and the flexible body 100 can be integrally molded. During the manufacturing process, the earplug 1000 is not manufactured by processing and assembling multiple parts separately, but by completing the manufacturing in a whole and continuous manner in one go, thus forming a complete and seamless whole. This manufacturing method can reduce assembly steps, improve production efficiency, ensure the structural strength and stability of the product, and reduce the possibility of defects in the connection parts. Figure 3 for Figure 1 The diagram shown is an exploded cross-sectional view of the earplug 1000. (Refer to...) Figure 3 In other embodiments, the mounting portion 200 and the flexible body 100 can be two separate components, which are assembled to form the earplug 1000. The mounting portion 200 may be provided with a mounting protrusion 300, and the flexible body 100 may be provided with a mounting groove 400. The mounting protrusion 300 is inserted into the mounting groove 400 to achieve the connection between the mounting portion 200 and the flexible body 100.
[0081] It should be noted that the first texture pattern 1 can be a recessed structure or a raised structure on the outer surface of the flexible body 100, or both a recessed structure and a raised structure can be provided on the outer surface of the flexible body 100 to increase the roughness of the outer surface of the flexible body 100, thereby providing frictional resistance opposite to the direction of movement when the earplug 1000 moves along the ear canal.
[0082] It should be noted that in some embodiments, the first texture pattern 1 can unidirectionally increase the frictional resistance when the earplug 1000 moves outward along the ear canal, without increasing the frictional resistance when the earplug 1000 is inserted into the ear canal. In other embodiments, the first texture pattern 1 can both increase the frictional resistance when the earplug 1000 moves outward along the ear canal and increase the frictional resistance when the earplug 1000 is inserted into the ear canal.
[0083] It should be noted that the first texture pattern 1 can be formed on the flexible body 100 by means of electrical discharge machining, texturing, mold forming, etc.
[0084] It should be noted that at least a portion of the flexible body 100 is spaced apart from the mounting portion 200 to form a void 500. This void 500 can be connected to the external environment. When the flexible body 100 deforms, the void 500 can accommodate the deformed flexible body 100.
[0085] The earplug 1000 provided in this application embodiment has a first textured pattern 1 on the outer surface of the flexible body 100. The first textured pattern 1 can increase the roughness of the outer surface of the flexible body 100, thereby providing frictional resistance opposite to the direction of movement when the earplug 1000 moves along the ear canal, reducing the probability that the earphone will easily fall out of the ear canal and improving the wearing stability of the earphone. At least a portion of the flexible body 100 is spaced apart from the mounting portion 200 to form a void 500. When the flexible body 100 is squeezed and deformed by the user's ear canal, the void 500 can accommodate the deformed flexible body 100. In this way, the deformation of the mounting portion 200 can be reduced or even prevented from deforming. This ensures the connection stability between the earplug 1000 and the earphone body, further ensuring the wearing stability of the earphone.
[0086] Figure 4 for Figure 1 A structural schematic diagram of the earbud 1000 from another perspective; Figure 5 for Figure 1 The diagram shows a structural schematic of the earbud 1000 from another perspective. (Refer to...) Figure 4 and Figure 5 In this embodiment of the application, the mounting part 200 of the earplug 1000 may be provided with a through hole structure so that the sound emitted by the device can pass through the through hole structure and enter the user's ear canal.
[0087] In some embodiments, the first texture pattern 1 is a concave-convex structure disposed on the outer surface of the flexible body 100, which is used to provide frictional resistance when the earplug 1000 moves outward along the ear canal.
[0088] In this embodiment, the first texture pattern 1 can only increase the frictional resistance when the earplug 1000 moves outward along the ear canal, without increasing the frictional resistance when the earplug 1000 enters the ear canal. In this way, the difficulty of wearing the headphones can be reduced, which helps the user to put the headphones in place and ensures the stability of the headphones.
[0089] Figure 6 for Figure 2 An enlarged structural diagram at point A in the diagram. (Refer to...) Figure 6 In some embodiments, the first texture pattern 1 includes one or more first recesses 101 recessed from the outer surface of the flexible body 100.
[0090] The first recess 101 increases the roughness of the outer surface of the flexible body 100, thereby increasing the friction between the flexible body 100 and the ear canal, reducing the probability of the earphone falling out of the ear canal, and improving the wearing stability of the earphone. The first texture pattern 1 does not form a structure protruding from the outer surface of the flexible body 100, so it will not affect the wearing of the earplug 1000, that is, it will not increase the frictional resistance when the earplug 1000 enters the ear canal. Thus, it can reduce the difficulty of wearing the earphone, help the user to put the earphone in place, and ensure the wearing stability of the earphone.
[0091] In this embodiment, the outer surface of the flexible body 100 is arc-shaped, and the first recess 101 can form a "barb" structure on the outer side of the flexible body 100. When the earplug 1000 has a tendency to move outward along the ear canal, the "barb" structure can abut against the inner wall of the ear canal to increase the movement resistance of the earplug 1000.
[0092] Continue to refer to Figure 1 In some embodiments, the first recess 101 is annular and surrounds the mounting portion 200.
[0093] The first recess 101 is set in a ring shape and surrounds the mounting part 200. The flexible body 100 is provided with the first recess 101 in all directions. In this way, the frictional resistance of the flexible body 100 when it moves outward along the ear canal can be increased at all circumferences, thereby further improving the wearing stability of the headphones.
[0094] Of course, in other embodiments, the first recess 101 may be strip-shaped, and the length of the first recess 101 may extend along the circumferential direction of the flexible body 100. In this embodiment, multiple first recesses 101 may also be provided, with at least two first recesses 101 arranged along the circumferential direction of the flexible body 100, and the ends of two adjacent first recesses 101 facing each other and spaced apart. In this way, the frictional resistance of the flexible body 100 when moving outward along the ear canal can be increased at all circumferential locations by increasing the number of first recesses 101 or increasing the length of the first recesses 101.
[0095] Continue to refer to Figure 1 In this embodiment of the application, a plurality of first recesses 101 are arranged sequentially along the direction from the front end of the flexible body 100 to the rear end of the flexible body 100.
[0096] It should be noted that the front and rear ends of the flexible body 100 are defined by the direction in which the flexible body 100 is inserted into the user's ear canal. When the flexible body 100 moves towards its front end, it can be inserted into the ear canal; when the flexible body 100 moves towards its rear end, it can be removed from the ear canal. Normally, when a user wears headphones, the headphone body is located outside the ear canal, and the headphone body is mounted on the rear end of the flexible body 100. In this embodiment, the direction from the rear end of the flexible body 100 to the front end is parallel to the Z-axis direction shown in the figure, and the positive Z-axis direction in the figure is the direction from the rear end of the flexible body 100 to the front end.
[0097] Multiple first recesses 101 are provided, and the multiple first recesses 101 are arranged sequentially along the direction from the front end of the flexible body 100 to the rear end of the flexible body 100. By increasing the number of first recesses 101, the frictional resistance of the flexible body 100 when moving outward along the ear canal can be increased, thereby enhancing the wearing stability of the headphones.
[0098] Reference Figure 2 and Figure 3 In some embodiments, the flexible body 100 is further provided with a second texture pattern 2 that matches the first texture pattern 1 on the side near the mounting portion 200, so that the thickness of the flexible body 100 is uniform.
[0099] A second textured pattern 2, matching the first textured pattern 1, is also provided on the side of the flexible body 100 near the mounting part 200, making the thickness of the flexible body 100 uniform. In this way, the second textured pattern 2 can form a protrusion in the recessed area of the first textured pattern 1. The uniform thickness of the flexible body 100 can ensure the strength of the flexible body 100 and reduce the possibility of damage due to insufficient thickness of the flexible body 100. That is, it can reduce the impact of the first textured pattern 1 on the strength of the flexible body 100.
[0100] In this embodiment, the first texture pattern 1 is a first recess 101 recessed from the outer surface of the flexible body 100. The first recess 101 is annular and surrounds the mounting portion 200. Thus, the second texture pattern 2 can be correspondingly set as a third protrusion 201 protruding from the side of the flexible body 100 near the mounting portion 200. The third protrusion 201 is annular and surrounds the mounting portion 200.
[0101] Figure 7 A cross-sectional view of the earplug 1000 provided in another embodiment of this application. (Refer to...) Figure 7In other embodiments, the side of the flexible body 100 near the mounting portion 200 may not have the second texture pattern 2, that is, the side of the flexible body 100 near the mounting portion 200 is smoothly provided, which can reduce the processing difficulty of the flexible body 100 and help reduce the cost of the earplug 1000.
[0102] In some embodiments, the depth of the first texture pattern 1 is less than or equal to the thickness of the flexible body 100.
[0103] It should be noted that when the depth of the first texture pattern 1 is different at different locations, the maximum depth of the first texture pattern 1 is less than or equal to the thickness of the flexible body 100.
[0104] The depth of the first texture pattern 1 is set to be less than or equal to the thickness of the flexible body 100. When the depth of the first texture pattern 1 is less than the thickness of the flexible body 100, the flexible body 100 will not form holes due to the first texture pattern 1, thus ensuring that the flexible body 100 has the corresponding strength. When the depth of the first texture pattern 1 is equal to the thickness of the flexible body 100, the first texture pattern 1 can form holes in the flexible body 100, making the shape of the flexible body 100 more diverse. In addition, when the flexible body 100 is provided with both the first texture pattern 1 and the second texture pattern 2, even if the depth of the first texture pattern 1 is equal to the thickness of the flexible body 100, the flexible body 100 will still not form holes, because the second texture pattern 2 will make up for the part of the flexible body 100 that is thinned by the first texture pattern 1, so that the thickness of the flexible body 100 is uniform throughout.
[0105] In this embodiment, the first texture pattern 1 is a first recess 101 recessed from the outer surface of the flexible body 100, and the depth of the first recess 101 is less than or equal to the thickness of the flexible body 100. Figures 1 to 7 The depth of the first recess 101 shown is less than the thickness of the flexible body 100.
[0106] Continue to refer to Figure 1 In some embodiments, the first recess 101 has a first surface 1011 facing the rear end of the flexible body 100, and the orthographic projection of the first surface 1011 onto the outer surface of the flexible body 100 is linear.
[0107] It should be noted that the orthographic projection of the first surface 1011 onto the outer surface of the flexible body 100 refers to the projection formed on the outer surface of the flexible body 100 after the projection light perpendicular to the outer surface of the flexible body 100 is projected onto the first surface 1011. When the outer surface of the flexible body 100 is a curved surface, the projection light can be perpendicular to the tangent direction of the outer surface of the corresponding area of the flexible body 100.
[0108] Setting the orthographic projection of the first surface 1011 onto the outer surface of the flexible body 100 to be a straight line simplifies the structure of the first recess 101 and facilitates the processing of the first recess 101, thus helping to reduce the processing cost of the earplug 1000.
[0109] Figure 8 This is a schematic diagram of the structure of an earplug 1000 provided in another embodiment of this application; Figure 9 for Figure 8 A magnified structural diagram at point B in the diagram. (Refer to...) Figure 8 and Figure 9 In other embodiments, the orthographic projection of the first surface 1011 onto the outer surface of the flexible body 100 is wavy.
[0110] It should be noted that in some embodiments, the orthographic projection of a portion of the first surface 1011 onto the outer surface of the flexible body 100 can be wavy, while the orthographic projection of another portion of the first surface 1011 onto the outer surface of the flexible body 100 can be straight. In other embodiments, the orthographic projection of all the first surfaces 1011 onto the outer surface of the flexible body 100 can be wavy, or the orthographic projection of all the first surfaces 1011 onto the outer surface of the flexible body 100 can be straight.
[0111] Setting the orthographic projection of the first surface 1011 onto the outer surface of the flexible body 100 to be wavy can further increase the roughness of the outer surface of the flexible body 100. This can further increase the difficulty of the earplug 1000 being removed from the ear canal, which helps to further improve the stability of wearing headphones.
[0112] In some embodiments, the first recess 101 has a second surface 1012 opposite to the first surface 1011, and the second surface 1012 can be smoothly connected to the outer surface of the flexible body 100, thereby reducing the resistance between the earplug 1000 and the ear canal when wearing headphones.
[0113] Reference Figure 9 The concave areas of the first surface 1011 of two adjacent wavy shapes are staggered.
[0114] By alternating the concave areas of two adjacent wavy first surfaces 1011, the roughness of the outer surface of the flexible body 100 can be balanced. This can balance the friction between the outer surface of the flexible body 100 and the ear canal, which helps to further improve the stability of wearing the headphones.
[0115] Reference Figure 8 and Figure 9 In this embodiment of the application, the staggered arrangement of the recessed areas of two adjacent wavy first surfaces 1011 can make the outer surface of the flexible body 100 have a fish scale pattern as a whole.
[0116] Figure 10 for Figure 8 The diagram shows a cross-sectional view of the earplug 1000. Figure 11 for Figure 10 A magnified structural diagram at point C. (Refer to...) Figure 10 and Figure 11 A first protrusion 102 is provided in the recessed area of the wavy first surface 1011.
[0117] It should be noted that the first protrusion 102 is disposed in the recessed area of the wavy first surface 1011, and the thickness of the first protrusion 102 is less than the depth of the first recess 101. That is, the surface of the first protrusion 102 will still form a height difference with the outer surface of the flexible body 100.
[0118] It should be noted that in some embodiments, the first protrusion 102 may be connected to the side of the wavy first surface 1011, while in other embodiments, the first protrusion 102 may not be connected to the side of the wavy first surface 1011.
[0119] By providing a first protrusion 102 within the recessed area of the wavy first surface 1011, that is, by utilizing the space within the recessed area of the wavy first surface 1011 to provide the first protrusion 102, the roughness of the outer surface of the flexible body 100 can be further increased. In this way, the frictional resistance of the flexible body 100 when it moves outward along the ear canal can be further increased, thereby enhancing the wearing stability of the headphones.
[0120] In some embodiments, the flexible body 100 near the mounting portion 200 is further provided with a second texture pattern 2 that matches the first texture pattern 1, so that the thickness of the flexible body 100 is uniform. Specifically, the orthographic projection of the first surface 1011 of the first recess 101 of the first texture pattern 1 onto the outer surface of the flexible body 100 is wavy, and the orthographic projection of the third convex portion 201 of the second texture pattern 2 corresponding to the first surface 1011 onto the outer surface of the flexible body 100 can also be wavy.
[0121] Figure 12 This is a schematic diagram of the structure of an earplug 1000 provided in another embodiment of this application; Figure 13 for Figure 12 A magnified structural diagram at point D in the diagram. (Refer to...) Figure 12 and Figure 13 In some embodiments, the first texture pattern 1 includes a plurality of second protrusions 104 formed in the flexible body 100, the end faces of which are used to adhere to the inner wall of the ear canal.
[0122] It should be noted that in some embodiments, the second protrusion 104 can be formed by protruding from the outer surface of the flexible body 100. In this case, the end of the second protrusion 104 can protrude outward from the outer surface of the flexible body 100. In other embodiments, a recessed structure can be provided from the outer surface of the flexible body 100, thereby forming a second protrusion 104 that protrudes relative to this recessed structure. In this embodiment, the end face of the second protrusion 104 is the outer surface of the flexible body 100.
[0123] During the wearing of the headphones, the end face of the second protrusion 104 is pressed to fit against the inner wall of the user's ear canal. Under the pressure, air flows out from between the end face of the second protrusion 104 and the inner wall of the user's ear canal, so that a negative pressure can be formed between the end face of the second protrusion 104 and the inner wall of the user's ear canal. At this time, the second protrusion 104 can adhere to the inner wall of the ear canal like a suction cup. When the flexible body 100 moves towards the outside of the ear canal, the force between the end face of the second protrusion 104 and the inner wall of the ear canal can prevent the flexible body 100 from moving, thus improving the wearing stability of the headphones.
[0124] Figure 15 This is a schematic diagram of the structure of a first texture pattern 1 provided in an embodiment of this application. (Refer to...) Figure 13 and Figure 15 In some embodiments, the orthographic projection pattern of the second protrusion 104 on the outer surface of the flexible body 100 is elliptical, circular, annular, triangular, quadrilateral, pentagonal or hexagonal.
[0125] The orthographic projection pattern of the second protrusion 104 on the outer surface of the flexible body 100 is elliptical, circular, annular, triangular, quadrilateral or pentagonal. The outer surface contour of the second protrusion 104 can be diversified. In this way, the surface of the second protrusion 104 can fit more closely to the inner wall of the ear canal, thereby increasing the frictional resistance when the flexible body 100 moves towards the outside of the ear canal and improving the wearing stability of the headphones.
[0126] Of course, the orthographic projection pattern of the second protrusion 104 on the outer surface of the flexible body 100 can also be hexagonal in a certain region, and circular in another region. In other embodiments, the orthographic projection pattern of the second protrusion 104 on the outer surface of the flexible body 100 can also be polygonal or irregular. This application does not impose any limitations on the embodiments described herein.
[0127] In some embodiments, the first texture pattern 1 includes a second recess 103 recessed from the outer surface of the flexible body 100. The orthographic projection pattern of the second recess 103 on the outer surface of the flexible body 100 is mesh-like, and the enclosed area of the second recess 103 forms a plurality of second protrusions 104.
[0128] It should be noted that in some embodiments, the flexible body 100 may simultaneously provide a first recess 101 and a second recess 103. In this case, the first recess 101 may be provided in a portion of the outer surface of the flexible body 100, and the second recess 103 may be provided in another portion of the outer surface. In other embodiments, the flexible body 100 may provide either the first recess 101 or the second recess 103 separately.
[0129] It should be noted that in some embodiments, the opening size and the bottom size of the second recess 103 can be equal, thus forming a columnar second protrusion 104; in other embodiments, the opening size of the second recess 103 can be larger than its bottom size, thus forming a frustum-shaped second protrusion 104; and in some embodiments, the opening size of the second recess 103 can be smaller than its bottom size, thus forming an inverted frustum-shaped second protrusion 104. Figure 14 for Figure 12 The diagram shows a cross-sectional view of the earplug 1000. Figure 16 for Figure 14 A magnified structural diagram at point E in the diagram. (Refer to...) Figure 14 and Figure 16 In this embodiment of the application, the opening size of the second recess 103 can be larger than its bottom size, and the second protrusion 104 is frustoconical.
[0130] The second concave portion 103 has a mesh-like pattern projected onto the outer surface of the flexible body 100, thereby enclosing and forming multiple second protrusions 104. Thus, the second protrusions 104 protrude relative to the second concave portion 103, and the end face of the second protrusion 104 is the outer surface of the flexible body 100. During the wearing of headphones, the wearing resistance generated by the second protrusions 104 can be reduced or even eliminated, thus making it easier to put the headphones in place.
[0131] Reference Figure 16 Along the direction in which the flexible body 100 is inserted into the ear canal, at least the depth of the portion of the second recess 103 located in the front end region of the flexible body 100 is less than the depth of the portion of the second recess 103 located in the middle region of the flexible body 100.
[0132] It should be noted that the direction in which the flexible body 100 is inserted into the ear canal is parallel to the Z-axis direction shown in the figure. At least the portion of the second recess 103 located in the front end region of the flexible body 100 may refer only to the front end region of the flexible body 100, or it may include both the front end region and the rear end region of the flexible body 100.
[0133] It should be noted that the depths of the second recess 103 in the front and rear regions of the flexible body 100 can be the same or different. From the front region to the middle region of the flexible body 100, the depth of the second recess 103 can gradually increase or increase in a stepwise manner; from the rear region to the middle region of the flexible body 100, the depth of the second recess 103 can gradually increase or increase in a stepwise manner.
[0134] Along the direction in which the flexible body 100 is inserted into the ear canal, at least the portion of the second recess 103 located in the front end region of the flexible body 100 is less than the depth of the portion of the second recess 103 located in the middle region of the flexible body 100. The roughness of the end region of the outer surface of the flexible body 100 is less than the roughness of the middle region of the outer surface of the flexible body 100. When the user wears the headphones, the roughness of the front end region of the flexible body 100 is smaller, making it easier to put the headphones in place. When the headphones are in place, the middle region of the flexible body 100 can abut against the ear canal. When the flexible body 100 moves toward the outside of the ear canal, the middle region of the flexible body 100 can provide greater frictional resistance, thus improving the wearing stability of the headphones.
[0135] In this embodiment, the flexible body 100 is further provided with a second texture pattern 2 that matches the first texture pattern 1 on the side near the mounting portion 200, so that the thickness of the flexible body 100 is uniform. The first texture pattern 1 includes a second recess 103 recessed from the outer surface of the flexible body 100. The orthographic projection pattern of the second recess 103 on the outer surface of the flexible body 100 is a mesh. Thus, the second texture pattern 2 can be correspondingly set as a fourth protrusion protruding from the side of the flexible body 100 near the mounting portion 200. The orthographic projection pattern of the fourth protrusion on the outer surface of the flexible body 100 is a mesh.
[0136] In some embodiments, the depth of the second recess 103 is less than or equal to the thickness of the flexible body 100. When the depth of the second recess 103 varies in different areas, the maximum depth of the second recess 103 is less than or equal to the thickness of the flexible body 100. For example, when the depth of the second recess 103 is less than the thickness of the flexible body 100, the flexible body 100 will not form a hole due to the second recess 103, thus ensuring that the flexible body 100 has the corresponding strength; when the depth of the second recess 103 is equal to the thickness of the flexible body 100, the second recess 103 can form a hole in the flexible body 100, making the shape of the flexible body 100 more diverse; furthermore, when the flexible body 100 is simultaneously provided with the first texture pattern 1 and the second texture pattern 2, even if the depth of the second recess 103 is equal to the thickness of the flexible body 100, the flexible body 100 will still not form a hole, because the second texture pattern 2 will supplement the portion of the flexible body 100 thinned by the second recess 103, so that the thickness of the flexible body 100 is uniform throughout.
[0137] This application also provides an earphone, including a body and an earplug 1000 as described in any of the above embodiments, the earplug 1000 being mounted on the body.
[0138] The earphone provided in this application embodiment has a first texture pattern 1 on the outer surface of the flexible body 100 of its earbud 1000. The first texture pattern 1 can increase the roughness of the outer surface of the flexible body 100, thereby increasing the frictional resistance when the earbud 1000 moves outward along the ear canal, reducing the probability that the earphone will easily fall out of the ear canal, and improving the wearing stability of the earphone.
[0139] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
