Description
Technical Field
[0001] This application relates to the field of electronic device technology, and in particular to an ear cap and an in-ear device. Background Technology
[0002] In-ear devices need to be inserted into the user's ear canal. During use, impurities in the ear canal, such as earwax and ear oil, often enter the in-ear device and negatively affect its function. Utility Model Content
[0003] An embodiment of this application provides an ear cap, the ear cap comprising:
[0004] The mounting section has a sound outlet channel. One end of the sound outlet channel has a first through hole on one side of the mounting section, and the other end has a second through hole on the other side of the mounting section. The mounting section is used to mount the device to the body of an in-ear device through the second through hole.
[0005] A first blocking part is disposed within the sound outlet channel. One end of the first blocking part is connected to the wall of the sound outlet channel, and the other end of the first blocking part is spaced apart from the wall of the sound outlet channel. A collection groove is provided on the side of the first blocking part facing the first through hole.
[0006] The second blocking part is provided in the sound outlet channel. One end of the second blocking part is connected to the wall of the sound outlet channel, and the other end of the second blocking part is spaced apart from the wall of the sound outlet channel.
[0007] The second blocking part and the first blocking part are arranged along the extension direction of the sound outlet channel, and the second blocking part is closer to the first through hole than the first blocking part.
[0008] Embodiments of this application also provide another ear cap, the ear cap comprising:
[0009] The mounting section has a sound outlet channel. One end of the sound outlet channel has a first through hole on one side of the mounting section, and the other end has a second through hole on the other side of the mounting section. The mounting section is used to mount the device to the body of an in-ear device through the second through hole.
[0010] Multiple first blocking parts are provided in the sound outlet channel and are respectively located at different positions on the wall of the sound outlet channel; one end of each of the multiple first blocking parts is connected to the wall of the sound outlet channel, and the other end of each of the multiple first blocking parts is spaced apart from the wall of the sound outlet channel, and a collection groove is provided on the side of each of the multiple first blocking parts facing the first through hole.
[0011] Along the extension direction of the sound outlet channel, the distance between the multiple first blocking parts and the end face of the mounting part having the second through hole is the same.
[0012] An embodiment of this application also provides an in-ear device, which includes a body and one of the two types of ear caps described above, with the ear cap installed on the body.
[0013] The beneficial effects of the ear cap provided in this application, which differ from existing technologies, are:
[0014] This application provides a first blocking part in the sound outlet channel within the mounting section, and a collection groove on the side of the first blocking part facing the first through hole. This allows the first blocking part to block earwax, earwax, or other impurities from entering the sound outlet channel of the ear cap, and the collection groove to collect these impurities, preventing them from entering the in-ear device through the second through hole. Furthermore, this application places one end of the first blocking part on the wall of the sound outlet channel, while the other end of the first blocking part is spaced apart from the wall of the sound outlet channel. This allows the first blocking part to not only block but also collect the impurities flowing along the wall of the sound outlet channel. The first blocking part can block impurities from entering the ear canal. When the ear cap is inserted into the ear canal and squeezed, the other end of the first blocking part can move towards the wall of the sound outlet channel under the action of external pressure based on the gap between it and the wall of the sound outlet channel, thereby reducing the resistance of the ear cap to the ear canal and improving the wearing comfort of the ear cap. This application can also provide a second blocking part on the side of the first blocking part near the first through hole, with one end of the second blocking part connected to the wall of the sound outlet channel and the other end spaced apart from the wall of the sound outlet channel, so that the second blocking part can block some impurities in front of the first blocking part, which is beneficial to improving the ear cap's ability to block impurities.

[0026] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.
[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] This application provides an in-ear device and its ear cap. In this application, the in-ear device is an electronic device that needs to be inserted into a user's ear canal, such as, but not limited to, in-ear headphones, in-ear hearing aids, and in-ear medical devices. The following description primarily uses in-ear headphones as an example.
[0029] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of an in-ear device provided in some embodiments of this application. Figure 2 This is a three-dimensional structural diagram of the ear cap provided in some embodiments of this application. Figure 3 yes Figure 2A three-dimensional structural diagram of the ear cap in the embodiment from another perspective.
[0030] In some embodiments, the in-ear device 10 includes an ear cap 11 and a body 12, with the ear cap 11 mounted on the body 12. The ear cap 11 may include a mounting portion 100, within which a sound outlet channel 101 is provided. One end of the sound outlet channel 101 has a first through hole 102 formed on one side of the mounting portion 100, and the other end has a second through hole 103 formed on the other side of the mounting portion 100. The first through hole 102 is located on the side of the mounting portion 100 used to contact the user's ear canal, and the second through hole 103 is located on the side of the mounting portion 100 used to connect to the body 12. The mounting portion 100 is used to be mounted to the body 12 through the second through hole 103.
[0031] Optionally, the in-ear device 10 includes a sound-generating component, and the audio played by the sound-generating component can be transmitted to the user's ear canal through the sound outlet channel 101. The first through-hole 102 of the ear cap 11 serves as the sound outlet. The sound-generating component of the body 12 can be inserted into the second through-hole 103 of the ear cap 11. In other embodiments, the sound-generating component of the in-ear device 10 may also be located outside the ear cap 11.
[0032] The ear cap 11 may also include a sealing portion 200. The sealing portion 200 is disposed around the periphery of the mounting portion 100. The sealing portion 200 may be integrally formed with the mounting portion 100. The sealing portion 200 may be generally bowl-shaped. When the ear cap 11 is inserted into the user's ear canal, the sealing portion 200 is compressed by the inner wall of the ear canal, thereby fitting tightly against the inner wall of the ear canal. The outer periphery of the sealing portion 200 may contact the inner wall of the ear canal to form a closed cavity. The sealing portion 200 and the mounting portion 100 may be made of the same material or different materials.
[0033] Please see Figure 4 and Figure 5 , Figure 4 This is a cross-sectional structural diagram of the ear cap provided in some embodiments of this application. Figure 5 This is a cross-sectional structural diagram of the ear cap provided in some other embodiments of this application.
[0034] In some embodiments, the ear cap 11 may include a first mounting section 111 and a second mounting section 112, wherein the first mounting section 111 has a higher hardness than the second mounting section 112. For example, the first mounting section 111 may be made of rigid plastic, and the second mounting section 112 may be made of soft plastic. A first through hole 102 may be provided in the second mounting section 112, and a second through hole 103 may be provided in the first mounting section 111.
[0035] The mounting portion 100 can be formed by the cooperation of a first mounting section 111 and a second mounting section 112. The portion of the mounting portion 100 that forms the first through hole 102 can be formed by the second mounting section 112, so that the ear cap 11 can contact the inner wall of the ear canal through the second mounting section 112. Since the second mounting section 112 is more flexible than the first mounting section 111, this helps to improve the comfort of the ear cap 11 when it is inserted into the ear, making it less likely for the ear cap 11 to damage the inner wall of the ear canal.
[0036] The portion of the mounting part 100 that forms the second through hole 103 can be formed by the first mounting section 111, so that the ear cap 11 can be connected to the body 12 through the first mounting section 111. Since the first mounting section 111 is harder than the second mounting section 112, this helps to improve the installation stability of the ear cap 11 on the body 12, making it less likely for the ear cap 11 to slide relative to the body 12.
[0037] The sealing portion 200 can also be formed by the second mounting section 112 to improve the ear cap 11's in-ear comfort. The first mounting section 111 can be integrally molded with the second mounting section 112, for example, by injection molding using two different plastic materials. In other embodiments, the first mounting section 111 can also be sealed to the second mounting section 112 in other ways. The hardness of the second mounting section 112 can be 15A-40A, for example, 20A, 25A, 30A, 35A, etc. Hardness unit A is a Shore A hardness scale, commonly used to measure the hardness of materials such as rubber, foam, and plastics. In other embodiments, the ear cap 11 can also be formed of a single material; for example, the ear cap 11 can be entirely formed of soft plastic.
[0038] In some embodiments, the ear cap 11 may further include a first blocking portion 300. The first blocking portion 300 may be disposed in the sound outlet channel 101. When the ear cap 11 is inserted into the ear canal for use, earwax, ear oil, and other impurities in the ear canal may enter the sound outlet channel 101 through the first through hole 102. The first blocking portion 300 can be used to block these impurities to prevent them from entering the body 12 of the in-ear device 10 through the second through hole 103.
[0039] Optionally, the first blocking part 300 may be provided with fine holes that make it difficult for impurities to pass through. In this way, the first blocking part 300 can not only block impurities such as earwax and earwax, but also allow airflow and audio to propagate better in the sound output channel 101. In other embodiments, the first blocking part 300 may also be a holeless structure.
[0040] The first blocking part 300 may have a collection groove 301 on the side facing the first through hole 102. The collection groove 301 is used to collect earwax, earwax, and other impurities. When earwax, earwax, or other impurities in the ear canal enter the sound outlet channel 101 of the ear cap 11, the first blocking part 300 can block these impurities and collect them using the collection groove 301. The collection groove 301 may be formed by a recess in the wall surface of the first blocking part 300 or by a protrusion on the wall surface of the first blocking part 300.
[0041] The first blocking part 300 can protrude from the wall of the sound outlet channel 101. When earwax, ear oil, and other impurities in the ear canal enter the sound outlet channel 101 through the first through hole 102, these impurities usually flow down along the wall of the sound outlet channel 101. When these impurities flow to the position of the first blocking part 300, they are blocked by the first blocking part 300 and flow onto the first blocking part 300, and are deposited in the collection tank 301. After the impurities that have accumulated in the collection tank 301 reach a certain level, the in-ear device 10 can be replaced with a new ear cap 11, or the ear cap 11 can be removed from the body 12 for cleaning.
[0042] One end of the first blocking part 300 can be connected to the wall of the sound outlet channel 101, and the other end of the first blocking part 300 can be spaced apart from the wall of the sound outlet channel 101. In other words, the first blocking part 300 can be a protrusion provided on the wall of the sound outlet channel 101, and there is a gap between the protruding end of the protrusion and other walls of the sound outlet channel 101.
[0043] When the ear cap 11 is inserted into the ear canal, its outer periphery will be squeezed by the inner wall of the ear canal. Since the material of the ear cap 11 is usually soft, the wall of its sound outlet channel 101 will shift towards the center of the sound outlet channel 101 under the action of external pressure. At this time, since the other end of the first blocking part 300 is spaced from the wall of the sound outlet channel 101, there is a displacement space between the first blocking part 300 and the wall of the sound outlet channel 101 along its protruding direction. Therefore, the first blocking part 300 can move towards the wall of the sound outlet channel 101 under the action of external pressure.
[0044] For example, the first blocking part 300 can protrude from the left side wall of the sound outlet channel 101, and the end of the first blocking part 300 away from the left side wall of the sound outlet channel 101 is spaced apart from the right side wall of the sound outlet channel 101. When the ear cap 11 is inserted into the ear canal and is squeezed by the inner wall of the ear canal, the left side wall of the sound outlet channel 101 will shift towards the center of the sound outlet channel 101, and drive the first blocking part 300 to move towards the right side wall of the sound outlet channel 101. At this time, since there is a gap between the first blocking part 300 and the right side wall of the sound outlet channel 101, the first blocking part 300 will not contact the right side wall of the sound outlet channel 101, which can prevent the ear cap 11 from exerting a resistance force opposite to the squeezing force on the inner wall of the ear canal due to the presence of the first blocking part 300.
[0045] Understandably, all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0046] In this embodiment, by designing the first blocking part 300 with the above-described structure, the first blocking part 300 not only blocks and collects impurities flowing down the wall of the sound outlet channel 101, but also, when the ear cap 11 is inserted into the ear canal and subjected to pressure, the other end of the first blocking part 300, based on the gap between it and the wall of the sound outlet channel 101, can move towards the wall of the sound outlet channel 101 under external pressure, thereby reducing the resistance of the ear cap 11 to the ear canal and improving the wearing comfort of the ear cap 11. When the in-ear device 10 is used, airflow or audio can pass through the gap between the first blocking part 300 and the wall of the sound outlet channel 101 to achieve transmission in the sound outlet channel 101.
[0047] The first blocking part 300 can cover part of the first through hole 102 along the extension direction of the sound outlet channel 101, so that when impurities in the ear canal enter the sound outlet channel 101 from the first through hole 102, the first blocking part 300 can block these impurities to prevent them from passing through the sound outlet channel 101.
[0048] In this document, the first blocking part 300 covering a portion of the first through hole 102 along the extending direction of the sound outlet channel 101 should be understood as the projection surface of the first blocking part 300 covering a portion of the first through hole 102 at its location. When the ear cap 11 is inside the user's ear canal, the coverage of the first through hole 102 by the first blocking part 300 along the sound outlet channel 101 can also be considered as the projection surface of the first blocking part 300 covering the first through hole 102 at the ear canal opening. The same applies to other similar descriptions in this document.
[0049] Please continue reading. Figure 4.
[0050] In some embodiments, the ear cap 11 may include a plurality of first blocking portions 300. The plurality of first blocking portions 300 are all disposed within the sound outlet channel 101 and are respectively disposed at different positions on the wall of the sound outlet channel 101. One end of each of the plurality of first blocking portions 300 is connected to the wall of the sound outlet channel 101, and the other end of each of the plurality of first blocking portions 300 is spaced apart from the wall of the sound outlet channel 101. A collection groove 301 may be provided on the side of each of the plurality of first blocking portions 300 facing the first through hole 102.
[0051] Optionally, multiple first blocking portions 300 may protrude from different side walls of the sound outlet channel 101. For example, at least one first blocking portion 300 may be provided on each of the opposite side walls of the sound outlet channel 101. One end of the first blocking portion 300 away from the wall on which it is provided is spaced apart from the other side wall of the sound outlet channel 101.
[0052] like Figure 4 As shown, two first blocking portions 300 protruding from different sidewalls of the sound outlet channel 101 can be arranged opposite each other, so that multiple first blocking portions 300 can cooperate to block and collect impurities entering the sound outlet channel 101 from different positions. In other embodiments, the multiple first blocking portions 300 can also be arranged in other ways, for example, the multiple first blocking portions 300 can be arranged along the extension direction of the sound outlet channel 101. The lengths of the multiple first blocking portions 300 along their protruding direction can be the same or different.
[0053] Along the extension direction of the sound outlet channel 101, a plurality of first blocking portions 300 can cooperate to cover most of the first through hole 102. For example, the coverage rate of the plurality of first blocking portions 300 on the first through hole 102 can be 80%-95%. The gaps between the plurality of first blocking portions 300 allow airflow and audio to pass through.
[0054] Optionally, the multiple first blocking portions 300 can be provided with fine holes that prevent impurities from passing through. In this way, the multiple first blocking portions 300 can not only block impurities such as earwax and earwax, but also allow airflow and audio to propagate better in the sound outlet channel 101. The fine holes can be, but are not limited to, formed in the wall of the collection groove 301. In other embodiments, the first blocking portions 300 can also be a non-porous structure.
[0055] In some embodiments, along the extending direction of the sound outlet channel 101, the distances between the plurality of first blocking portions 300 and the end face of the mounting portion 100 where the second through hole 103 is provided can be the same. Taking the second through hole 103 being provided on the bottom end face of the mounting portion 100 as an example, the distances between the plurality of first blocking portions 300 and the bottom end face of the mounting portion 100 can be the same, so that the plurality of first blocking portions 300 can cooperate to block impurities at the same height position. In other embodiments, the distance between some of the plurality of first blocking portions 300 and the end face of the mounting portion 100 where the second through hole 103 is provided can also be different from that of other portions of the plurality of first blocking portions 300. For example, the setting position of some first blocking portions 300 is higher than that of others.
[0056] Along the extending direction of the sound outlet channel 101, the distances between the plurality of first blocking portions 300 and the end face of the mounting portion 100 where the first through hole 102 is provided can also be the same. In other embodiments, the distance between a portion of the plurality of first blocking portions 300 and the end face of the mounting portion 100 where the first through hole 102 is provided can also be different from that of another portion of the plurality of first blocking portions 300.
[0057] It should be understood that the terminology used in this specification and appended claims is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. Similarly, the terms “first” and “second” in the description of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features. Furthermore, the term “multiple” in the description of this application means two or more, unless otherwise explicitly specified.
[0058] Please see Figures 5 to 7 , Figure 5 This is a cross-sectional structural schematic diagram of the ear cap provided in some other embodiments of this application. Figure 6 yes Figure 5 A schematic diagram of the in-ear device before it is inserted into the ear canal, as shown in this embodiment. Figure 7 yes Figure 5 A schematic diagram of the in-ear device being inserted into the ear canal in the embodiment.
[0059] In some embodiments, the ear cap 11 may include a first blocking portion 300 and a second blocking portion 400. The number of the first blocking portion 300 and the second blocking portion 400 may be one or more. Both the first blocking portion 300 and the second blocking portion 400 are disposed within the sound outlet channel 101.
[0060] The second blocking part 400 can be provided with fine holes that make it difficult for impurities to pass through. In this way, the second blocking part 400 can not only block impurities such as earwax and earwax, but also allow airflow and audio to propagate better in the sound output channel 101. In other embodiments, the second blocking part 400 can also be a holeless structure.
[0061] One end of the second blocking part 400 is connected to the wall of the sound outlet channel 101, and the other end of the second blocking part 400 is spaced apart from the wall of the sound outlet channel 101. The second blocking part 400 can be used in conjunction with the first blocking part 300 to block impurities from entering the sound outlet channel 101. When the ear cap 11 is inserted into the ear canal, similar to the first blocking part 300, there is a displacement space between the second blocking part 400 and the wall of the sound outlet channel 101, which can prevent the ear cap 11 from exerting additional resistance on the inner wall of the ear canal due to the presence of the second blocking part 400.
[0062] The second blocking portion 400 and the first blocking portion 300 can be arranged along the extending direction of the sound outlet channel 101. The second blocking portion 400 is closer to the first through hole 102 than the first blocking portion 300. In some embodiments, the first blocking portion 300 and the second blocking portion 400 can be respectively provided at different positions on the wall surface of the sound outlet channel 101, and the protrusion directions of the first blocking portion 300 and the second blocking portion 400 are different. In other words, the first blocking portion 300 and the second blocking portion 400 can be respectively protruding on different side walls of the sound outlet channel 101, for example... Figure 5 As shown, the first blocking part 300 protrudes from the left side wall of the sound outlet channel 101, and the second blocking part 400 protrudes from the right side wall of the sound outlet channel 101.
[0063] Along the extending direction of the sound outlet channel 101, both the first blocking part 300 and the second blocking part 400 partially cover the first through hole 102, thereby allowing the first blocking part 300 and the second blocking part 400 to block impurities entering the sound outlet channel 101 from different positions. Impurities blocked by the second blocking part 400 may deposit on the second blocking part 400 or flow to the first blocking part 300 and deposit in the collection tank 301. The first blocking part 300 and the second blocking part 400 may, but are not limited to, protrude from the opposite side walls of the sound outlet channel 101.
[0064] Optionally, along the extending direction of the sound outlet channel 101, the first blocking portion 300 and the second blocking portion 400 cooperate to completely cover the first through hole 102. Thus, when impurities in the ear canal enter the sound outlet channel 101, regardless of where they enter from, the impurities will be blocked by either the first blocking portion 300 or the second blocking portion 400. Impurities blocked by the first blocking portion 300 will deposit in the collection groove 301, and impurities blocked by the second blocking portion 400 will deposit on the second blocking portion 400 or further flow to the first blocking portion 300. In other embodiments, along the extending direction of the sound outlet channel 101, the first blocking portion 300 and the second blocking portion 400 may also cooperate to partially cover the first through hole 102.
[0065] The coverage rate of the first blocking part 300 over the first through hole 102 can be 40%-60%, such as 45%, 50%, 55%, etc. The coverage rate of the second blocking part 400 over the first through hole 102 can also be 40%-60%, such as 45%, 50%, 55%, etc. For example, the first blocking part 300 can cover half of the first through hole 102, and the second blocking part 400 can cover the other half of the first through hole 102. In this case, the coverage rate of both the first blocking part 300 and the second blocking part 400 over the first through hole 102 is 50%.
[0066] Understandably, the coverage of the first through hole 102 by the aforementioned blocking portion refers to the coverage of the first through hole 102 by the blocking portion along the extending direction of the sound outlet channel 101. In other embodiments, the coverage rate of the first through hole 102 by the first blocking portion 300 and the second blocking portion 400 is not limited to the above embodiments.
[0067] In other embodiments, the second blocking part 400 may also protrude from the first blocking part 300 on the same side wall of the sound outlet channel 101. The length of the second blocking part 400 along its protruding direction may be less than that of the first blocking part 300, so that the second blocking part 400 can block a portion of impurities in front of the first blocking part 300, thereby improving the ear cap 11's ability to block impurities.
[0068] In other embodiments, the second blocking portion 400 in the above embodiments can be replaced by the first blocking portion 300. For example, the ear cap 11 may include a plurality of first blocking portions 300 arranged along the extension direction of the sound outlet channel 101 and protruding on different side walls of the sound outlet channel 101. The plurality of first blocking portions 300 may cover a portion of the first through hole 102 along the extension direction of the sound outlet channel 101 and cooperate to completely cover the first through hole 102.
[0069] Please see Figure 5 and Figure 8 , Figure 8This is a cross-sectional structural diagram of the ear cap provided in some other embodiments of this application.
[0070] In some embodiments, the first blocking portion 300 and the second blocking portion 400 are spaced apart along the extending direction of the sound outlet channel 101, and the gap between the first blocking portion 300 and the second blocking portion 400 communicates with the first through hole 102. Audio in the sound outlet channel 101 can be transmitted to the first through hole 102 through the gap between the first blocking portion 300 and the second blocking portion 400.
[0071] The first blocking portion 300 may include a first blocking wall 310 and a second blocking wall 320. The first blocking wall 310 protrudes from the wall surface of the sound outlet channel 101. The second blocking wall 320 protrudes from the side of the first blocking wall 310 facing the first through hole 102 and cooperates with the first blocking wall 310 to form a collection groove 301. Optionally, one end of the first blocking wall 310 is provided on the wall surface of the sound outlet channel 101, and the other end is provided with the second blocking wall 320, so as to maximize the space of the collection groove 301. The second blocking wall 320 is spaced apart from the wall surface of the sound outlet channel 101.
[0072] The first blocking wall 310 can be approximately perpendicular to the extension direction of the sound outlet channel 101, and the second blocking wall 320 can be approximately parallel to the extension direction of the sound outlet channel 101. The first blocking wall 310 can be used to block impurities from entering the sound outlet channel 101 through the first through hole 102, and the second blocking wall 320 can be used to prevent impurities on the first blocking wall 310 from detaching from the first blocking wall 310, so that the impurities can be deposited and condensed in the collection tank 301.
[0073] The second blocking portion 400 can cover the second blocking wall 320 along the extending direction of the sound outlet channel 101, and a gap is formed between the second blocking portion 400 and the second blocking wall 320 communicating with the first through hole 102. In some embodiments, the second blocking portion 400 may include a third blocking wall 410 and a fourth blocking wall 420. The fourth blocking wall 420 protrudes from the side of the third blocking wall 410 away from the first through hole 102. The gap is formed between the fourth blocking wall 420 and the second blocking wall 320. In this embodiment, the size of the gap can be adjusted by designing the size of the fourth blocking wall 420. One end of the third blocking wall 410 can be disposed on the wall surface of the sound outlet channel 101, and the fourth blocking wall 420 can be disposed on the other end of the third blocking wall 410.
[0074] In this embodiment, the third blocking wall 410 can be parallel to the first blocking wall 310, thereby blocking a portion of impurities. In other embodiments, the third blocking wall 410 can also be inclined relative to the first blocking wall 310. For example, one end of the third blocking wall 410 on the wall surface can be farther away from the first through hole 102 relative to its other end, so that the third blocking wall 410 is inclined relative to the first blocking wall 310 towards the first through hole 102, thereby improving the blocking ability of the second blocking part 400 to block impurities.
[0075] The fourth blocking wall 420 can be parallel to the second blocking wall 320 or inclined relative to the second blocking wall 320. The ends of the first blocking wall 310 and the third blocking wall 410 can overlap along the extension direction of the sound outlet channel 101, and the second blocking wall 320 and the fourth blocking wall 420 can respectively protrude from the overlapping portions of the first blocking wall 310 and the third blocking wall 410 along the extension direction of the sound outlet channel 101. In other embodiments, the second blocking portion 400 may include the third blocking wall 410, such as... Figure 5 As shown, the gap between the second blocking part 400 and the first blocking part 300 can be formed by the third blocking wall 410 and the second blocking wall 320 spaced apart.
[0076] Optionally, along the extending direction of the sound outlet channel 101, both the first blocking wall 310 and the third blocking wall 410 partially cover the first through hole 102, and the first blocking wall 310 and the third blocking wall 410 cooperate to completely cover the first through hole 102. The first blocking wall 310 and the third blocking wall 410 may partially overlap along the extending direction of the sound outlet channel 101, or they may each cover two portions of the first through hole 102 along the extending direction of the sound outlet channel 101. The extending direction of the sound outlet channel 101 can be... Figure 4 and Figure 5 and Figure 8 and Figure 10 The upward direction is shown.
[0077] In this embodiment, since the first blocking part 300 and the second blocking part 400 are arranged at intervals along the arrangement direction of the sound outlet channel 101, and the first blocking part 300 and the second blocking part 400 are on different horizontal planes, when the ear cap 11 is inserted into the ear canal, both the first blocking part 300 and the second blocking part 400 have displacement space and will not interfere with each other. This avoids the ear cap 11 exerting additional resistance on the inner wall of the ear canal due to the presence of the first blocking part 300 and the second blocking part 400 when it is inserted into the ear canal. It can be understood that the resistance exerted by the ear cap 11 on the inner wall of the ear canal is the force generated by the ear cap 11 to restore its original shape when it is deformed by compression.
[0078] It should be noted that the second blocking part 400 provided in this application embodiment is not limited to the above structure. For example, the side of the second blocking part 400 facing the first through hole 102 may be provided with a groove similar to the collection groove 301 to improve the blocking and collection ability of the second blocking part 400 for impurities.
[0079] Please see Figure 9 and Figure 10 , Figure 9 This is a three-dimensional structural diagram of the ear cap provided in some other embodiments of this application. Figure 10 yes Figure 9 A cross-sectional view of the ear cap in the embodiment.
[0080] In some embodiments, the first blocking part 300 may be connected to the second blocking part 400. At least one of the first blocking part 300 and the second blocking part 400 may have a third through hole 302 communicating with the first through hole 102. Audio in the sound output channel 101 can be transmitted to the first through hole 102 through the third through hole 302.
[0081] Compared to the embodiment where the first blocking part 300 and the second blocking part 400 are spaced apart, this embodiment connects the first blocking part 300 and the second blocking part 400 and provides a third through hole 302 in at least one of them, which further improves the blocking ability of the first blocking part 300 and the second blocking part 400 against impurities. Moreover, since the first blocking part 300 and the second blocking part 400 are arranged along the extension direction of the sound outlet channel 101, and the ends of both that are away from the wall on which they are located are spaced apart from the wall on the other side of the sound outlet channel 101, the first blocking part 300 and the second blocking part 400 still have displacement space when the ear cap 11 is inserted into the ear canal, thereby avoiding excessive resistance to the inner wall of the ear canal due to the presence of the first blocking part 300 and the second blocking part 400 when the ear cap 11 is inserted into the ear canal.
[0082] The first blocking portion 300 may include a first blocking wall 310 and a second blocking wall 320. The second blocking wall 320 protrudes from the side of the first blocking wall 310 facing the first through hole 102 and cooperates with the first blocking wall 310 to form a collection groove 301. One end of the first blocking wall 310 is disposed on the wall surface of the sound outlet channel 101, and the second blocking wall 320 may be disposed at the other end of the first blocking wall 310. The second blocking portion 400 may include a third blocking wall 410, which may be connected to the end of the second blocking wall 320 away from the first blocking wall 310.
[0083] The second blocking wall 320 may have a third through hole 302 connecting to the first through hole 102. The number of third through holes 302 can be one or more. For example... Figure 9As shown, the second blocking wall 320 may be provided with a plurality of third through holes 302 arranged in an array. The second blocking wall 320 is bent relative to the first blocking wall 310 and also bent relative to the third blocking wall 410. For example, the second blocking wall 320 may be perpendicular to both the first and third blocking walls 310. Other features of the first blocking portion 300 and the second blocking portion 400 have been described above and will not be repeated here.
[0084] Please continue reading. Figure 8 and Figure 10 In some embodiments, the first blocking portion 300 may be as follows: Figure 8 As shown, it is formed by the first mounting section 111. In other embodiments, the first blocking portion 300 may be as follows: Figure 10 The second mounting section 112 is formed as shown. The second mounting section 112 may also form a second blocking portion 400, a sealing portion 200, and a portion of the mounting portion 100. The thickness of the first blocking wall 310 and the third blocking wall 410 can both be 0.1-0.6 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. The thickness of the second blocking wall 320 can be approximately the same as the first blocking wall 310. The thickness of the fourth blocking wall 420 can be approximately the same as the third blocking wall 410. The thickness of the sealing portion 200 can also be 0.1 mm-0.6 mm. By designing the thickness of the first blocking portion 300 and the second blocking portion 400 within the above range, the ear cap 11 can smoothly form the first blocking portion 300 and the second blocking portion 400 while avoiding excessive space occupation by the first blocking portion 300 and the second blocking portion 400, thus preserving the original function of the ear cap 11.
