Description

Technical Field

[0001] The utility model relates to the field of ear clip type earphone accessories, in particular to an auxiliary sleeve and an ear clip type earphone. Background Art

[0002] Bluetooth headsets apply Bluetooth technology to hands-free earphones, allowing users to communicate freely and easily in a variety of ways without the entanglement of wires. Ear clip earphones are a type of Bluetooth headset. They are roughly C-shaped and clamp onto the ear to effectively prevent the earphones from falling out. Compared to in-ear headphones, ear clip earphones clamp onto the ear helix and do not intrude into the ear canal. Therefore, the ear clip earphone structure reduces the risk of otitis externa caused by long-term wear, resulting in the increasing use of ear clip earphones.

[0003] The current ear-clip earphone structure basically includes a first earphone shell, a second earphone shell and an elastic bridge. The first earphone shell and the second earphone shell are roughly bean-shaped and are respectively installed on both sides of the elastic bridge. The elastic bridge has a C-shaped curved structure. Therefore, the first earphone shell, the second earphone shell and the inner side of the elastic bridge form a clamping space clamped on the ear. When the first earphone shell and the second earphone shell are adjusted to move closer or farther away from each other, the width of the clamping space can be adjusted, that is, the size of the clamping gap can be adjusted.

[0004] However, after the current ear clip-on headphones are manufactured, the gap between the two earphone shells is basically fixed when the headphones are in a static state, that is, the clamping gap is basically fixed within a certain range. Therefore, when the headphones are clamped to the ears for use, even if the user previously pried the two earphone shells apart to allow the headphones to be placed on the ears, the headphones will gradually return to their original position after the force is removed. Ultimately, the two earphone shells will gradually return to the initial clamping gap. Therefore, the clamping gap of most ear clip-on headphones is fixed at the beginning of the design and is difficult to adjust later. However, due to the different sizes and structures of different users' ears, especially for users with smaller ears, the headphones often fall off or become uncomfortable to wear after wearing, which can easily affect use. Therefore, the clamping gap of current ear clip-on headphones is difficult to adjust, making it difficult to adapt to users with different ear structures and having a limited scope of application.

[0005] To address this problem, in the prior art, a silicone kit is provided on the inner side of the earphone housing to adjust the clamping gap, so that the earphones fit closely to the ears and improve wearing stability. For example, the Chinese patent with patent number CN202223229598.0 discloses an ear-clip earphone, which is installed with a curved silicone on the inner side of both earphone housings. When wearing the earphones, the two curved silicones work and shrink at the same time, so that it is easy to wear, does not scratch the ears, and does not squeeze the ears to cause pain when wearing. When the user wears it in place, the curved silicone will rebound. The soft curved silicone can be deformed and fit the ears according to each person's ear shape, which is more comfortable and better protects the ears when worn for a long time without causing pain. When the earphones are removed, the curved silicone will shrink again according to the shape of the ear, and the earphones can be easily detached from the ears without scratching or squeezing the ears. At the same time, a gap is left between the curved silicone and the plastic hard plastic column to ensure the normal shrinkage of the curved silicone. Therefore, to a certain extent, this patent changes the clamping gap by using curved silicone to adapt to different users.

[0006] Among them, according to the content of the patent, it can be clearly known that the curved silicone and the earphone shell are fixedly connected. Therefore, the ear-clip earphone will have the following defects: after the earphones have been used for a long time, the surface will inevitably become dirty. At this time, the curved silicone needs to be removed for cleaning, but due to the fixed connection between the curved silicone and the earphone shell, the earphones will be difficult to clean. Moreover, the fixed connection between the curved silicone and the earphone shell makes it inconvenient for the subsequent replacement and maintenance of the silicone shell.

[0007] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0008] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide an auxiliary sleeve and an ear clip-on earphone. Through the design of the auxiliary sleeve, the present invention effectively solves the problem that the traditional ear clip-on earphones are difficult to adapt to users with different ear structures due to the difficulty in adjusting the clamping gap due to differences in ear sizes and shapes among different people, and are inconvenient to clean, replace and maintain.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] An auxiliary sleeve is a semi-enclosed structure that is hollow and has an opening at the top. The upper opening of the auxiliary sleeve is a sleeve interface, and the middle space of the auxiliary sleeve is a fitting cavity. The sleeve interface is used for allowing the shell of an ear clip-on headphone to pass through and be placed in the fitting cavity, thereby placing the auxiliary sleeve on the shell of the ear clip-on headphone.

[0011] As a preferred embodiment, the auxiliary sleeve includes a first side wall, a second side wall and an arc-shaped connecting portion; the arc-shaped connecting portion is an arc-shaped curved structure, and is connected to the edges of the first side wall and the second side wall on both sides respectively, and the first side wall, the second side wall and the arc-shaped connecting portion surround the fitting cavity in the middle to form the fitting cavity, and the upper opening of the fitting cavity is the fitting port.

[0012] As a preferred solution, the auxiliary sleeve fits against the ear at the second side wall, and the second side wall is a soft material sheet.

[0013] As a preferred solution, the sleeve interface is provided with an extension portion extending upward on the side that fits the ear, and the extension portion is used to improve the installation stability of the auxiliary sleeve on the earphone.

[0014] As a preferred solution, the auxiliary sleeve is provided with an avoidance hole, which is located at the bottom of the sleeve cavity and communicated with the sleeve cavity.

[0015] As a preferred solution, the auxiliary sleeve is a sleeve made of soft material.

[0016] As a preferred solution, the auxiliary sleeve is a silicone sleeve.

[0017] As a preferred solution, the auxiliary sleeve is a PC material sleeve.

[0018] As a preferred solution, the structure of the sleeve cavity gradually shrinks from the middle to the sleeve port.

[0019] A clip-on earphone having any of the above-mentioned auxiliary sleeves detachably mounted thereon; the clip-on earphone comprises a first earphone body, a second earphone body, and an elastic bridge, the elastic bridge being C-shaped and connected to the first earphone body and the second earphone body at both ends; the gap between the first earphone body and the second earphone body being a clamping gap, the auxiliary sleeve being mounted on the first earphone body and / or the second earphone body to adjust the size of the clamping gap.

[0020] Compared with the prior art, the present invention has obvious advantages and beneficial effects:

[0021] 1. The auxiliary sleeve provided in the present application is a semi-enclosed structure that is hollow and has an opening at the top. The upper opening of the auxiliary sleeve is a sleeve opening, and the middle space of the auxiliary sleeve is a fitting cavity. The sleeve opening is used to allow the housing of the ear clip-on earphone to pass through and be placed into the fitting cavity, thereby fitting the auxiliary sleeve onto the housing of the ear clip-on earphone. Therefore, in the present application, by detachably attaching the auxiliary sleeve to the first earphone body or the second earphone body of the ear clip-on earphone, the thickness of the auxiliary sleeve can be used to adjust the gap between the two earphone bodies accordingly, that is, to change the clamping gap of the ear clip-on earphone, thereby adapting to users with different ear structures and improving the applicability of the earphone.

[0022] 2. The auxiliary cover provided in this application has a detachable design. When it is not needed, or when the auxiliary cover is damaged or dirty, it can be removed from the earphone, which facilitates the replacement, maintenance, and cleaning of the auxiliary cover. At the same time, its structure is simple and easy to disassemble and assemble.

[0023] 3. The auxiliary sleeve of the present application can be designed with adjustable thickness during production. For example, for a certain type of earphone, multiple auxiliary sleeves of different thicknesses can be set to match the earphone. When the auxiliary sleeves of different thicknesses are put on the earphone, different earphone clamping gaps can be obtained, thereby further improving the applicability of the earphone and making the earphone suitable for all users as much as possible.

[0024] In order to more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Please refer to Figures 1 to 4 As shown, it shows the specific structure of an embodiment of the present utility model.

[0038] In the description of the present invention, it should be noted that directional words, such as the terms "up", "down", "front", "back", "left", "right", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the drawings or during normal wear and use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific protection scope of the present invention.

[0039] [Example 1]

[0040] See also Figures 1-4 This embodiment provides an auxiliary sleeve, wherein the auxiliary sleeve 40 is a semi-enclosed structure that is hollow and has an opening at the top; the upper opening of the auxiliary sleeve 40 is a sleeve port 5, and the middle space of the auxiliary sleeve 40 is a fitting cavity 3. The structure of the fitting cavity 3 is adapted to the structure of the corresponding earphone shell, and the sleeve port 5 is used for allowing the shell of the ear clip-on earphone to pass through and be placed in the fitting cavity 3, thereby mounting the auxiliary sleeve on the shell of the ear clip-on earphone. Therefore, in this embodiment, by detachably mounting the auxiliary sleeve 40 on the first earphone body 10 or the second earphone body 20 of the ear clip-on earphone, the thickness of the auxiliary sleeve 40 can be used to adjust the gap between the two earphone bodies accordingly, that is, to change the clamping gap 11 of the ear clip-on earphone, thereby adapting to users with different ear structures, especially users with different ear thicknesses, and ultimately improving the applicability of the earphone.

[0041] In addition, in actual production, the thickness design of the auxiliary sleeve 40 can be varied. For example, for a certain type of earphone, multiple auxiliary sleeves 40 of different thicknesses can be matched at the same time. When the auxiliary sleeves 40 of different thicknesses are put on the earphone, different earphone clamping gaps 11 can be obtained, thereby further improving the applicability of the earphone and making the earphone suitable for all users as much as possible.

[0042] In this embodiment, the auxiliary sleeve 50 includes a first sidewall 1, a second sidewall 2, and an arcuate connecting portion 4. The arcuate connecting portion 4 is an arcuate curved structure, connected to the edges of the first sidewall 1 and the second sidewall 2 on both sides. This allows the first sidewall 1, the second sidewall 2, and the arcuate connecting portion 4 to form a semi-enclosed structure, which encloses the fitting cavity 3 in the middle. The upper opening of the fitting cavity 3 is the fitting port 5. The fitting port 5 is used to allow the earphone housing to pass through, allowing the earphone housing to be placed in the fitting cavity 3. The structure of the fitting cavity 3 is compatible with that of the corresponding earphone housing, thereby stably fitting the auxiliary sleeve 40 on the earphone housing.

[0043] During actual use, the ear-clip earphones are clamped behind the ears, and the second side wall 2 of the auxiliary sleeve 40 is fitted against the ears. In order to improve comfort, in this embodiment, the second side wall 2 is set as a soft material sheet, such as a silicone material sheet, so as to utilize the soft properties of silicone to improve the wearing comfort of the earphones. At the same time, the second side wall 2 has a certain elasticity, so that after the earphones are worn, when the second side wall 2 forms a certain rebound, the earphones can fit more closely to the skin of the ear, thereby improving the wearing stability of the earphones.

[0044] Furthermore, in this embodiment, the auxiliary sleeve 40 is configured as a soft material sleeve as a whole. Specifically, the auxiliary sleeve 40 is a silicone sleeve as a whole. Therefore, due to the characteristics of the silicone material, the auxiliary sleeve 40 as a whole has a certain elasticity, which can facilitate the sleeve interface 5 to be stretched and expanded under force, thereby facilitating the auxiliary sleeve 40 to be put on the earphone shell, or facilitating the auxiliary sleeve 40 to be removed from the earphone.

[0045] In another embodiment, the second side wall 2 of the auxiliary sleeve 40 is configured as a soft material sheet, while other structures of the auxiliary sleeve 40 can be configured as hard material structures, thereby ensuring the comfort of the second side wall 2 when worn.

[0046] Of course, since the user experience may vary, for some users, setting the second side wall 2 as a soft material sheet may not necessarily improve comfort. Therefore, in other embodiments, the auxiliary sleeve 40 as a whole can be set as a hard material sleeve, specifically a PC material sleeve.

[0047] Therefore, in the present application, a variety of auxiliary sleeves 40 with different soft and hard structures can be provided, so that the auxiliary sleeve 40 with corresponding material structure can be selected according to actual needs.

[0048] In this embodiment, the sleeve interface 5 is provided with an extension portion 6 extending upward on the side that fits the ear. The extension portion 6 can increase the contact area between the auxiliary sleeve 40 and the earphone shell, thereby increasing the contact friction between the two, and ultimately improving the installation stability of the auxiliary sleeve 40 on the earphone.

[0049] In this embodiment, a avoidance hole 7 is provided on the auxiliary sleeve 40, and the avoidance hole 7 is located at the bottom of the sleeve cavity 3 and is connected to the sleeve cavity 3. By providing the avoidance hole 7 at the bottom of the auxiliary sleeve 40, the sleeve cavity 3 can be made consistent with the pressure of the external environment, thereby preventing negative pressure from occurring in the sleeve cavity 3 when the auxiliary sleeve 40 is removed, thereby preventing the auxiliary sleeve 40 from being sucked tightly onto the earphone shell and affecting the removal of the auxiliary sleeve 40.

[0050] In this embodiment, the structure of the fitting cavity 3 gradually shrinks from the middle to the fitting port 5. Therefore, after the auxiliary sleeve 40 is put on the earphone shell, its upper structure will form a limiting effect to prevent the auxiliary sleeve 40 from falling off.

[0051] It is worth noting that because the earphone housing, that is, the intermediate structure between the first earphone body 10 and the second earphone body 40 of the earphone, is larger than the socket interface 5, when the auxiliary sleeve 40 is installed on the earphone housing or removed from the earphone housing, the auxiliary sleeve 40 structure at the socket interface 5 will be forced to expand outward, thereby allowing the earphone housing to pass through and realize the removal and assembly of the auxiliary sleeve 40. Specifically, when the auxiliary sleeve 40 is made of a soft material, it has a certain elasticity, thus facilitating the stretching of the socket interface 5 and thus facilitating the removal and assembly of the auxiliary sleeve 40; when the auxiliary sleeve 40 is made of a hard material, its structure still has a certain degree of stretchability, that is, when the auxiliary sleeve 40 is made of a hard material, the structure at the socket interface 5 can still be stretched to a certain extent, and it is necessary to ensure that the auxiliary sleeve 40 can be installed on the earphone housing or removed from the earphone.

[0052] [Example 2]

[0053] Please continue reading Figures 1-4 The present application also provides an ear-clip earphone, which is detachably installed with the above-mentioned auxiliary sleeve 40; the ear-clip earphone includes a first earphone body 10, a second earphone body 20 and an elastic bridge 30, and the elastic bridge 30 is a C-shaped structure and is connected to the first earphone body 10 and the second earphone body 20 at both ends respectively; the gap between the first earphone body 10 and the second earphone body 20 is a clamping gap 11, and the auxiliary sleeve 40 is provided on the first earphone body 10 and / or the second earphone body 20 to adjust the size of the clamping gap 11.

[0054] The key point of the design of the present invention lies in the design of the auxiliary sleeve. The upper opening of the auxiliary sleeve 40 is a sleeve port 5, and the middle space of the auxiliary sleeve 40 is a sleeve cavity 3. The sleeve port 5 is used for the housing of the ear clip-on earphone to pass through and be placed in the sleeve cavity 3, thereby sleeve-mounting the auxiliary sleeve 40 on the housing of the ear clip-on earphone. Therefore, in the present application, by detachably mounting the auxiliary sleeve 40 on the first earphone body 10 or the second earphone body 20 of the ear clip-on earphone, the thickness of the auxiliary sleeve 40 can be used to adjust the gap between the two earphone bodies accordingly, that is, to change the clamping gap 11 of the ear clip-on earphone, thereby adapting to users with different ear structures and improving the applicability of the earphone.

[0055] Secondly, the auxiliary cover 40 provided in this application has a detachable design. When it is not needed, or when the auxiliary cover 40 is damaged or dirty, it can be removed from the earphone, which facilitates the replacement, maintenance, and cleaning of the auxiliary cover 40. At the same time, its structure is simple and easy to disassemble and assemble.

[0056] In addition, the auxiliary sleeve 40 of the present application can be designed with an adjustable thickness during production. For example, for a certain type of earphone, multiple auxiliary sleeves 40 of different thicknesses can be provided to match the earphone. When the auxiliary sleeves 40 of different thicknesses are put on the earphone, different earphone clamping gaps 11 can be obtained, thereby further improving the applicability of the earphone and making the earphone suitable for all users as much as possible.

[0057] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
