Description

Technical Field

[0001] The present disclosure relates to earplugs, particularly sound-insulating earplugs. Background Art

[0002] Sound-insulating earplugs are generally made of silicone, low-pressure foam material, or high-elastic polyester material, and are generally used in noisy or sleep scenarios where noise interference needs to be avoided. If the sound-insulating earplugs are used during sleep, it is required that the earplug structure is small and light. Generally, "U"-shaped earplugs with a moderate length are used on the market. That is, after one end of the "U"-shaped earplug is inserted into the ear, the other end can abut against the inner wall of the cymba of the human body, thereby enhancing the stability of the earplug in the human ear and preventing the "U"-shaped earplug from falling off the ear when the human body turns over during sleep.

[0003] The above-mentioned "U"-shaped earplugs solve the problem of noise interference well. However, when the earplugs are applied to the sleep scenario, especially when the human body sleeps on its side, the end of the "U"-shaped earplug is prone to pressing on the cymba of the human body, causing a foreign body sensation. Summary of the Invention

[0004] To solve the above problems, the present application discloses a sound-insulating earplug that fits the inner shape of the ear after being inserted into the human body and does not cause an obvious foreign body sensation when being pressed.

[0005] The present application provides a sound-insulating earplug, including an earplug body and an ear cap, wherein the earplug body includes:

[0006] A main body, the main body includes an insertion part for inserting the ear cap;

[0007] A support part, the support part is fixed at one end of the main body, and a part of the structure of the support part is used for receiving the tragus of the human body;

[0008] A guiding angle is provided at one end of the insertion part away from the support part, and the ear cap is inserted into the main body through the guiding angle.

[0009] In the above embodiment, a part of the structure of the support part is adapted to the ear and can be used for receiving the tragus of the human body, so that the earplug will not press the ear bone in the ear and cause discomfort when worn; in addition, a guiding angle is provided at the end of the insertion part, and when the ear cap falls off or the earplug needs to be inserted, rapid insertion can be achieved through the guiding angle.

[0010] In some embodiments of the present application, a recessed part is formed by recessing in the middle of the support part, the recessed part is used for receiving the tragus of the human body, and the included angle formed between the two ends of the support part connected to the recessed part and the inner side wall of the recessed part is 60° - 100°, preferably 70°.

[0011] In the above embodiments, the ear bones at the helix foot are different in size for different human bodies. For people with larger ear bones, when using earplugs with an angle of less than 60°, the earplugs will not be stuck and will be lifted up and away from the ears. For people with smaller ear bones, when using earplugs with an angle of more than 100°, the earplugs will become loose and unable to be fixed to the ears. Therefore, after a large number of experiments, this application limits the angle between 60° and 100° to fit the ear bones of most people. More preferably, when the angle is set at 70°, the formed earplugs can fit the ear bones of most people and achieve the best support and stabilization effect.

[0012] In some embodiments of the present application, one end of the recessed portion is used to abut against the inner wall of the human tragus, and the other side of the supporting portion facing away from the recessed portion is used to abut against the side wall of the antihelix of the human body.

[0013] In the above embodiment, by setting the positions of the supporting portion and the recessed portion, the earplug can be firmly inserted into the human ear and is not easy to fall off.

[0014] In some embodiments of the present application, the interior of the support portion is a hollow structure.

[0015] In some embodiments of the present application, the outer peripheral shape of the support portion is the same as the shape of the interior after hollowing out, both of which are moon-shaped or heart-shaped, or the hollow structure of the support portion is moon-shaped or heart-shaped.

[0016] In the above embodiments, the outer shape of the support portion and the inner hollow shape are consistent, both are moon-shaped or heart-shaped, which are beautiful as a whole and easy to take. It is worth noting that most people have a bulge at the helix foot, and the depression in the middle of the moon-shape or heart-shape can just accommodate the ear bone at the helix foot, thereby achieving mutual adaptation between the earplug and the human body, avoiding the ear being compressed by the earplug and causing discomfort to the human body.

[0017] In some embodiments of the present application, the main body further includes a connecting portion, which is formed by bending and extending from one end of the supporting portion, and is arranged between the supporting portion and the inserting portion, and the ear cap is snap-connected to the connecting portion.

[0018] In some embodiments of the present application, the connecting portion is recessed and formed with at least two grooves around its outer periphery, the at least two grooves are arranged side by side and spaced apart, and the grooves are engaged with the ear cap.

[0019] In the above embodiment, two grooves are provided, and the ear cap can be inserted into different grooves, thereby changing the depth of the earplug inserted into the ear. The specific selection of which groove to use can be adjusted according to the human ear and environmental conditions.

[0020] In some embodiments of the present application, the guiding angle is an inclined surface structure with a gradually decreasing diameter from one end of the insertion portion close to the connection portion towards the direction away from the connection portion.

[0021] In some embodiments of the present application, the length of the main body along the earplug insertion direction is 6.3 - 8.5 mm.

[0022] In the above embodiments, when the length of the main body is less than 6.3 mm or greater than 8.5 mm, there will be a phenomenon that the contact between the ear and the earplug is insufficient or the foreign body sensation in the ear is obvious. Therefore, through testing, the length of the main body in the present application is set between 6.3 - 8.5 mm.

[0023] In some embodiments of the present application, the earplug is a multi-layer earplug.

[0024] In the above embodiments, in a noisy environment, when it is necessary to avoid being disturbed by noise, the double-layer earplug can make the earplug contact the ear more deeply and isolate the external sound.

[0025] In some embodiments of the present application, the outer peripheral diameter of the main body is 5.2 - 6.5 mm, preferably 6.0 mm.

[0026] In the above embodiments, when the outer peripheral diameter of the main body is less than 5.2 mm, there is no foreign body sensation when wearing the earplug, but it is too thin to be easily worn into the ear; when the outer peripheral diameter of the main body exceeds 6.5 mm, there will be some foreign body sensations when lying on the side after wearing the earplug, which is not suitable. Therefore, the outer peripheral diameter of the main body is designed between 5.2 - 6.5 mm to meet the wearing comfort; importantly, when the outer peripheral diameter of the main body is controlled at 6.0 mm, it is not only easy to insert into the ear for wearing, but also there will be no obvious foreign body sensation after long-term wearing.

[0027] In some embodiments of the present application, the earplug is made of a soft material or a plastic material. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the description of the present application in this specification are only for the purpose of describing specific embodiments, and are not intended to limit the present application.

[0036] Terms such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The symbol "-" should be understood to include its end point values.

[0037] An embodiment of the present application provides a sound-insulating earplug 100 for insertion into the human ear. The earplug 100 includes an earplug body 10 and an ear tip 70. The earplug body 10 includes a main body 11 and a support part 13 integrally connected to the end of the main body 11. A part of the structure of the support part 13 is used to accommodate the tragus of the human body, and another part of the structure of the support part 13 is used to abut against the inner wall of the ear, so that the earplug 100 is not pressed by the ear and can be stably supported on the ear.

[0038] Next, in combination with the attached Figures 1-3 , some embodiments of the present application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] Referring to Figures 1-2 , the sound-insulating earplug 100 includes an earplug body 10 and an ear tip 70. The ear tip 70 includes an inner circumference and an outer circumference connected to each other. One side of the outer circumference fits against the ear and isolates external noise, and the other side of the outer circumference is provided with an inner circumference. The inner circumference is provided with a limiting part 71, and the limiting part 71 is engaged with the earplug body 10, so that the ear tip 70 and the earplug body 10 are combined to form the earplug 100. It can be understood that the end of the ear tip 70 away from the earplug body 10, that is, the position where the inner circumference and the outer circumference are connected to each other, can be closed or open. In this embodiment, it is preferably closed. On the one hand, it avoids impurities in the ear from entering the ear tip 70, thereby affecting the cleanliness of the ear tip 70; on the other hand, it improves the noise reduction effect of the earplug.

[0040] Furthermore, the ear tip 70 can be set in a single layer or multiple layers. The multi-layer ear tip 70 has better sound insulation effect and can be specifically selected according to actual needs.

[0041] The earplug body 10 includes an integrally formed main body 11 and a support portion 13. The main body 11 is used to insert into the ear tip 70 and is inserted into the ear together with the ear tip 70 to prevent the ear from being interfered by external noises. A partial structure of the support portion 13 is adapted to the tragus of the human body to avoid pressing the ear after the earplug 100 is worn and bringing discomfort to the human body.

[0042] The main body 11 is cylindrical and is formed by bending and extending from one end of the support portion 13. Its length along the insertion direction of the ear tip 70 is set to be 6.3 - 8.5 mm. Within this length range, the main body 11 can ensure comfortable wearing of the human body and there will be no foreign body sensation when turning over during sleep. In some embodiments, the length of the main body 11 can be any value among 6.3 mm, 7.3 mm, 7.8 mm, 8.5 mm or any value within 6.3 - 8.5 mm. In this embodiment, the length direction of the main body 11 is defined as 6.3 mm. At this length, after the formed earplug 100 is worn, the human body will not have a foreign body sensation.

[0043] In addition, since the main body 11 is the part that directly contacts and fits with the ear, and the sizes of everyone's ears are different and there is no model distinction for the main body 11, it is particularly important whether the designed and formed main body 11 can adapt to the ear requirements of most people and bring a comfortable feeling to the human body. In some embodiments, the outer diameter of the main body 11 can be any value among 5.2 mm, 5.3 mm, 5.5 mm, 5.7 mm and 6.5 mm or an interval value within 5.2 - 6.5 mm. In this embodiment, the outer diameter of the main body 11 is set to 6.0 mm. This diameter can not only enable the human body to experience the best comfort, but also be easy to wear.

[0044] Furthermore, an insertion portion 30 and a connection portion 50 are provided on the main body 11. The connection portion 50 is formed by bending and extending from one end of the support portion 13 and is cylindrical. The insertion portion 30 protrudes and extends from the end of the connection portion 50 away from the support portion 13. The outer diameter of the insertion portion 30 is equal to the outer diameter of the connection portion 50. A guiding angle is provided at the end of the insertion portion 30 away from the support portion 13, and the guiding angle can facilitate the insertion of the ear tip 70. The guiding angle is an inclined surface structure with a gradually decreasing diameter from the end of the insertion portion 30 close to the connection portion 50 towards the direction away from the connection portion 50. In particular, the human body will replace the ear tip 70 irregularly. When replacing a new ear tip 70, insert one end of the ear tip 70 along the guiding angle into the earplug body 10, and the quick combination of the ear tip 70 and the earplug body 10 can be achieved quickly.

[0045] The connecting portion 50 is disposed between the inserting portion 30 and the supporting portion 13, and is used to accommodate the inner peripheral end of the ear cap 70 and prevent the ear cap 70 from falling off. Specifically, the connecting portion 50 is concavely formed with a first groove 51 and a second groove 53 around its outer periphery, and the first groove 51 and the second groove 53 are arranged side by side and spaced apart. When the human body does not need to be completely isolated from noise, the ear cap 70 can be inserted into the first groove 51, so that the limiting portion 71 is engaged in the first groove 51; when the human body needs to be completely isolated from the interference of noise and enter a sleeping state, the ear cap 70 can be inserted into the second groove 53, so that the limiting portion 71 is engaged in the second groove 53, thereby achieving the effect of deep contact between the earplug 100 and the ear.

[0046] Reference Figure 1 and Figure 3 The support portion 13 and the connecting portion 50 are fixedly connected, and the angle between the support portion 13 and the connecting portion 50 is not less than 90°. The partial structural shape of the support portion 13 is adapted to the helix crus of the human body, so that the support portion 13 can accommodate the helix crus, and the earplug 100 will not be compressed by the helix crus after being worn into the human ear; in addition, a part of the structure of the support portion 13 abuts against the inside of the ear, so that the earplug 100 is firmly combined with the human body as a whole, and the human body will not fall off when turning over during sleep. Specifically, the middle of the support portion 13 is concave to form a concave portion 90. For the sake of aesthetic design, the support portion 13 is in the shape of a "moon" or a "heart", and the middle of the "moon" or "heart" is the concave portion 90. Since most human bodies have an ear bone protruding at the helix crus, the concave portion 90 in the middle of the support portion 13 can accommodate the ear bone on the helix crus, so that the human body will not be compressed by the ear bone when wearing the earplug to rest.

[0047] One end of the junction of the support portion 13 and the recessed portion 90 can abut against the inner wall of the human tragus, so that the support portion 13 can be supported in the ear; further, in order to strengthen the fit between the support portion 13 and the ear, the other side of the support portion 13 away from the recessed portion 90 can abut against the outer wall of the antihelix of the human body. In the above structural design, the contact points between the earplug 100 and the human ear include at least three, namely, the insertion portion 30, the end of the recessed portion 90 and the side of the support portion 13 away from the recessed portion 90. Here, the three points just form a triangle shape, so that the earplug 100 and the human ear can fit firmly.

[0048] Similarly, there are slight differences in the size of the tragus of the human body. Therefore, it is necessary to design the moon-shaped or heart-shaped recess of the support part 13 so that it can adapt to the size of the tragus of most people and meet the comfort of the human body at the same time. Specifically, the included angle formed between the two end parts connected to the recess part 90 and the inner side wall of the recess part 90 is 60°-100°. After testing, when the included angle formed between the two ends of the recess part 90 and the inner side wall of the recess part 90 is between 60°-100°, the above effects can be achieved. In some embodiments, the included angle can be set to any value among 60°, 65°, 70°, 80°, 90°, 100° or any value between 60°-100°. In particular, when the included angle is set at 70°, it can adapt to different human bodies, neither the problem of the earplug 100 tilting up nor the situation that the earplug 100 is too loose to be fixed will occur.

[0049] The thickness of the support part 13 is also extremely important. If the thickness is too large, it will cause discomfort to the human ear. If the thickness is too thin, it is not easy to be inserted into the ear. In this application, the thickness of the support part 13 is set between 3mm and 4mm, specifically it can be any value between 3.1mm, 3.4mm, 3.7mm, 4mm, 3.1mm or other values within the above range. When the thickness of the support part 13 is set to 3.5mm, the formed earplug 100 is relatively light and easy to be inserted into the ear, and no foreign body sensation will be generated after wearing for a long time.

[0050] Importantly, in order to make the overall appearance of the earplug 100 beautiful, the inside of the support part 13 is hollowed out, and the shape of the hollow is the same as the external shape of the support part 13, both being moon-shaped or heart-shaped. At the same time, since the inside of the support part 13 is hollowed out, when the box for storing the earplug 100 cannot store the earplug, the hollow setting of the support part 13 can also be used to hang and store the earplug 100 to avoid loss.

[0051] Since the sound insulation earplug 100 is applied to scenarios such as work, study, travel and sleep, and there may be a situation of wearing it for a long time, therefore, the whole of the sound insulation earplug 100 is supported by a soft material or a plastic material, and the soft material includes but is not limited to silicone, foam and other soft materials, etc.

[0052] When using the sound-insulating earplug 100 of the present application, the ear cap 70 is inserted along the guiding angle of the insertion portion 30, and further pushed so that the limiting portion 71 of the ear cap 70 is snapped into the first groove 51 or the second groove 53 of the connecting portion 50. At the same time, the limiting portion 71 abuts against the bottom surface of the first groove 51 or the bottom surface of the second groove 53 to prevent the ear cap 70 from falling off the earplug body 10. After the earplug 100 is worn in the human ear, the moon-shaped or heart-shaped recess 90 on the support portion 13 exactly accommodates the ear bone on the crus of helix of the human ear. One end of the joint between the support portion 13 and the recess 90 exactly abuts against the inner side wall of the tragus of the human body, and the other side of the support portion 13 away from the recess 90 also exactly abuts against the outer side wall of the antitragus of the human body, so as to ensure the stable combination of the earplug 100 and the human body, and it is not easy to fall off even when turning over during sleep.

[0053] In addition, the inside of the support portion 13 is hollowed out, and for aesthetic design, both the inside and the outside of the support portion 13 are presented in a "moon shape" or "heart shape".

[0054] In addition, those of ordinary skill in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the scope of the substantial spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope of the disclosure of the present application.
