Description

Technical Field

[0001] This utility model belongs to the technical field of hearing accessories, and in particular relates to an earplug and a hearing aid. Background Technology

[0002] Earplugs are a key acoustic component whose main function is to securely fix the speaker (receiver) inside (or partially insert into) the ear canal, ensuring that the speaker can stably convert electrical signals into sound and transmit them efficiently to the wearer.

[0003] When earplugs are worn and inserted into the ear canal, they need to contact the canal wall for stable positioning. However, due to individual differences in ear canal shape among users, existing earplug designs often cannot fully adapt to diverse ear canal structures, easily causing excessive pressure in certain areas. This uneven pressure distribution not only affects wearing comfort but may also lead to ear canal pressure pain after prolonged use, thus reducing the user experience. Utility Model Content

[0004] In view of this, it is necessary to provide an earplug and hearing aid to solve the above-mentioned technical problems.

[0005] An earplug includes an earplug body, the earplug body including a bottom wall and a peripheral side wall, the peripheral side wall surrounding and forming a cylindrical cavity, the peripheral side wall having a central axis, one end of the peripheral side wall along the central axis being connected to the bottom wall, and the other end of the peripheral side wall along the central axis forming an opening, the opening communicating with the cavity; Specifically, two points are arbitrarily selected on the outer wall surface of the peripheral sidewall, and the two points are arranged on opposite sides of the central axis. Furthermore, the cross section of the peripheral sidewall passing through the two points is configured as an ellipse.

[0006] Understandably, configuring the shape of any cross-section of the outer wall of the earplug body into an ellipse makes the design of the outer wall of the earplug more consistent with the ear canal wall of the human ear. This prevents the earplug from causing local pressure on the ear canal wall when worn, thus improving wearing comfort and avoiding ear canal pressure pain caused by long-term wear.

[0007] In one embodiment, the outer diameter of the peripheral sidewall gradually increases along the central axis and from the bottom wall toward the opening.

[0008] Understandably, the design of the outer wall of the earplug makes it more suitable for the human ear canal, thus improving the stability of the earplug when worn.

[0009] In one embodiment, along the central axis and in the direction from the bottom wall toward the opening, the outer diameter of the peripheral sidewall first gradually increases and then gradually decreases.

[0010] Understandably, the design of the outer wall of the earplug makes it more suitable for the human ear canal, thus improving the stability of the earplug when worn.

[0011] In one embodiment, the earplug body further includes a reinforcing rib, which is disposed on the inner wall surface of the peripheral sidewall; The reinforcing rib is arranged perpendicular to the central axis of the peripheral sidewall.

[0012] It is understandable that reinforcing ribs are used to support the main body of the earbud, so that the earbud can be durable and resistant to deformation while maintaining a soft overall structure, preventing significant plastic deformation during long-term wear.

[0013] In one embodiment, the number of reinforcing ribs is configured to be multiple, and the multiple reinforcing ribs are arranged sequentially at intervals along the central axis of the axial sidewall.

[0014] In one embodiment, the earplug further includes a foolproof part disposed on the outside of the earplug body and connected to the peripheral sidewall.

[0015] Understandably, designing a foolproof structure on the earbuds can guide users to correctly identify the wearing direction, thereby avoiding discomfort or poor sealing caused by incorrect orientation.

[0016] In one embodiment, the earplug body includes a bottom wall and a peripheral side wall, the bottom wall is disposed at one end of the peripheral side wall and connected to the peripheral side wall, and the outer wall surface is disposed on the peripheral side wall; A connecting protrusion is formed on the bottom wall, and the connecting protrusion is disposed in the area where the peripheral sidewall is located.

[0017] In one embodiment, a sound outlet is provided on the bottom wall; Alternatively, a sound outlet hole may be provided on the peripheral sidewall.

[0018] In one embodiment, the number of earbud bodies is configured to be two, and the two earbud bodies can be connected by a connecting protrusion; Alternatively, the number of earbud bodies is configured to be one, and a connecting protrusion is formed on the bottom wall, the connecting protrusion being at least partially disposed within the cavity.

[0019] In one embodiment, the earplug is made of silicone or rubber, and the Shore A hardness of the earplug is configured to be 20A-60A.

[0020] This application also provides a hearing aid, including the earplug described above.

[0021] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: The earplug and hearing aid claimed in this application configure the shape of any cross section of the outer wall surface of the earplug body as an ellipse, so that the design of the outer wall surface of the earplug is more in line with the ear canal wall of the human ear canal. This can prevent the earplug from causing local compression to the ear canal wall when worn, thereby improving wearing comfort and avoiding ear canal pressure pain caused by long-term wear.

[0035] The earplug 100 claimed in this application specifically refers to an earplug used in a hearing aid. Of course, the earplug 100 can also be used in headphones for general listening.

[0036] like Figures 1 to 8As shown, the earplug 100 provided in this application includes an earplug body 10, which includes a bottom wall 110 and a peripheral sidewall 120. The peripheral sidewall 120 surrounds and forms a cylindrical cavity 121. The peripheral sidewall 120 has a central axis L. One end of the peripheral sidewall 120 along the central axis L is connected to the bottom wall 110, and the other end of the peripheral sidewall 120 along the central axis L forms an opening 122, which communicates with the cavity 121. Two points are arbitrarily selected on the outer wall surface 11 of the peripheral sidewall 120, and the two points are arranged on opposite sides of the central axis L. Furthermore, the cross section of the peripheral sidewall 120 passing through the two points is configured as an ellipse. Here, when the user wears the earplug 100, the outer wall surface 11 of the peripheral sidewall 120 is used to contact the ear canal wall. It is understood that the earplug 100 of this application has an elliptical cross section passing through two points on the peripheral sidewall 120, that is, the shape of any cross section of the outer wall surface 11 of the peripheral sidewall 120 is configured as an ellipse, so that the design of the outer wall surface 11 of the earplug 100 is more in line with the ear canal wall of the human ear canal. This can prevent the earplug 100 from causing local compression to the ear canal wall when worn, thus improving the wearing comfort and avoiding the problem of ear canal pressure pain caused by long-term wear.

[0037] It should be noted that any two points on the outer wall surface 11 of the aforementioned peripheral sidewall 120 are arranged on opposite sides of the central axis. Specifically, these two points are respectively arranged on two lines intersecting the cross-section of the peripheral sidewall 120 and the outer wall surface 11. The cross-section is the section on the earbud body 10 that extends along the central axis of the peripheral sidewall 120 and passes through the central axis. Specifically, it can be described as follows: Figure 2 , Figure 4 and Figure 6 As shown.

[0038] For example, such as Figure 2 As shown, when two points A and B are selected on the outer wall surface 11 of the peripheral sidewall 120, the cross-section of the earplug 100 on the peripheral sidewall 120 when it passes through points A and B is as follows. Figure 3 As shown; or, as Figure 2 As shown, when two points C and D are selected on the outer wall surface 11 of the peripheral sidewall 120, the cross-section of the earplug 100 on the peripheral sidewall 120 when it passes through points C and D is as follows. Figure 4 As shown.

[0039] In some embodiments, the earbud 100 is made of silicone or rubber. In this embodiment, the earbud 100 is made of silicone.

[0040] Meanwhile, the earbud 100 can be manufactured using a one-piece injection molding method, which facilitates the production and manufacturing of the earbud 100.

[0041] In some embodiments, the Shore A hardness of the earplug 100 is configured to be 20A-60A. Specifically, the Shore A hardness of the earplug 100 may be 20A, 30A, 40A, 50A or 60A, etc., making the overall structure of the earplug 100 soft, so as to further improve the wearing comfort of the earplug 100.

[0042] like Figures 1 to 8 As shown, in some embodiments, along the central axis L and from the bottom wall 110 toward the opening 122, the outer diameter of the peripheral sidewall 120 gradually increases, or the outer diameter of the peripheral sidewall 120 first gradually increases and then gradually decreases. That is, the earplug body 10 of the embodiment is generally olive-shaped or partially olive-shaped, which makes the shape of the earplug 100 more suitable for the human ear canal, thus improving the stability of the earplug 100 when worn. Here, the earplug 100 with a gradually increasing outer diameter of the peripheral sidewall 120 can specifically be a closed earplug or an open earplug; while the earplug with a gradually increasing outer diameter of the peripheral sidewall 120 that first gradually increases and then gradually decreases is a semi-closed earplug.

[0043] like Figures 1 to 8 As shown, in some embodiments, the earplug 100 further includes a reinforcing rib 20, which is disposed on the inner wall surface 12 of the peripheral sidewall 120; wherein, the reinforcing rib 20 is disposed perpendicular to the central axis L of the earplug body 10. That is to say, the earplug 100 of the embodiment can use the reinforcing rib 20 to support the earplug body 10, so that the earplug 100 can ensure durability and deformation resistance while maintaining a flexible overall structure, and prevent the earplug 100 from undergoing significant plastic deformation during long-term wear.

[0044] like Figures 1 to 8 As shown, in some embodiments, the number of reinforcing ribs 20 is configured to be multiple, and the multiple reinforcing ribs 20 are arranged sequentially at intervals along the central axis L of the peripheral sidewall 120, so that the earplug body 10 has multiple reinforcing ribs 20 supporting it in the central axis L of the peripheral sidewall 120, and the earplug body 10 as a whole is structurally supported.

[0045] Here, the number of reinforcing ribs 20 can be set to two, three, four, six, etc. Of course, the number of reinforcing ribs 20 can be set according to the specific needs of use, which will not be elaborated here.

[0046] like Figures 1 to 8 As shown, in some embodiments, the earplug 100 also includes a foolproof part 30, which is disposed on the outside of the earplug body 10 and connected to the peripheral sidewall 120. Specifically, the foolproof part 30 can be integrated with the peripheral sidewall 120, so that when the user wears the earplug 100, the foolproof part 30 can be used to identify the direction in which the earplug 100 is worn, thereby avoiding discomfort or poor sealing caused by incorrect orientation.

[0047] like Figure 2 As shown, in some embodiments, a sound outlet 101 is provided on the bottom wall 110, allowing the earplug 100 to output sound outward through the sound outlet 101 on the bottom wall 110. That is, the earplug 100 in this embodiment is configured as a semi-closed earplug. Here, the number of sound outlets 101 is configured to be two, and the two sound outlets 101 are symmetrically arranged on both sides of the connecting protrusion 40. It can be understood that in other embodiments, the number of sound outlets 101 may also be configured to be one, three, four, or even more, and the arrangement position of the sound outlets 101 on the bottom wall 110 may also be specifically set according to the usage requirements, which will not be elaborated here.

[0048] like Figure 5 , Figure 6 As shown, in some embodiments, a sound outlet hole 101 is provided on the peripheral sidewall 120, allowing the earplug 100 to output sound outward through the sound outlet hole 101 on the peripheral sidewall 120. That is, the earplug 100 in this embodiment is configured as an open-back earplug. Here, the number of sound outlet holes 101 is configured to be four, and the four sound outlet holes 101 are arranged at intervals along the circumferential direction of the earplug body 10. It can be understood that in other embodiments, the number of sound outlet holes 101 may also be configured to be two, three, five, or even more, and the arrangement position of the sound outlet holes 101 on the peripheral sidewall 120 may also be specifically set according to the usage requirements, which will not be elaborated here.

[0049] like Figure 7 , Figure 8 As shown, in some embodiments, the number of earplug bodies 10 is configured to be two, and the two earplug bodies 10 can be connected to each other via a connecting protrusion 40. That is, the earplug 100 of the embodiment is configured as a fully enclosed earplug, wherein the connecting protrusion 40 is used to connect to the earplug connector on the receiver module of the hearing aid. Here, the connecting protrusion 40 is configured as a semi-enclosed structure, using the closed end of the connecting protrusion 40 to prevent foreign objects such as earwax and bodily fluids from entering the earplug 100.

[0050] like Figure 2 , Figure 6 and Figure 8 As shown, in some embodiments, the number of earplug bodies 10 is configured to be one, and a connecting protrusion 40 is formed on the bottom wall 110, the connecting protrusion 40 being at least partially disposed within the cavity 121. That is, the earplug 100 of the embodiment is configured as an open earplug or a semi-closed earplug, wherein the connecting protrusion 40 is built into the earplug body 10 for connecting to the earplug connector on the receiver module of the hearing aid. Here, the connecting protrusion 40 is configured as a semi-closed structure, using the closed end of the connecting protrusion 40 to prevent foreign objects such as earwax and bodily fluids from entering the earplug 100.

[0051] In addition, this application also provides a hearing aid, including the earplug 100 described above.

[0052] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
