The ear canal shape of different users cannot be exactly the same, even if the ear canal shape of the left ear and the ear canal shape of the right ear of the same user are slightly different. Even if the earcap made of elastic solid materials is adopted, the earcap deforms after being inserted into the auditory meatus, the shape of the earcap cannot be completely attached to the auditory meatus of all users, and due to the unmatched situation, the users can feel uncomfortable after wearing the earcap for a long time, and the wearing comfort of the earcap is affected.
Referring to fig. 1 and 2, an ear cap 100 is provided. The earcap 100 comprises a resilient earcap body 10 and at least one fluid portion 20. The earcap body 10 includes a first surface 11 and a second surface 12 opposite to each other, and the earcap body 10 is provided with a through hole 13 penetrating through the first surface 11 and the second surface 12. At least one fluid portion 20 is embedded inside the earcap body 10, and the fluid portion 20 is spaced apart from the through-hole 13.
The utility model provides an earcap 100 is through at the embedded at least one fluid portion 20 of establishing of elastic earcap body 10, when earcap 100 received user's ear canal extrusion, fluid portion 20 can drive earcap body 10 and take place deformation, and make the shape after earcap 100 deformation can use this earcap 100's user's ear canal laminating at this moment completely, thereby the travelling comfort of wearing of earcap 100 has been improved, also can reduce the noise entering people's ear in the outside air simultaneously, with this function of making an uproar falls of earphone 300 (shown in figure 7) of realizing.
The following is further described with reference to the accompanying drawings.
Referring to fig. 1 and 2, the ear cap 100 includes an elastic ear cap body 10 and at least one fluid portion 20, the fluid portion 20 is embedded inside the ear cap body 10, and the fluid portion 20 and the through hole 13 are arranged at an interval, when the user wears the ear cap 100, that is, when the ear cap 100 is plugged into the ear canal of the user, the fluid portion 20 can drive the ear cap body 10 to deform under the extrusion of the ear canal, so that the ear cap 100 is completely attached to the ear canal of the user.
Specifically, the earcap body 10 includes a first surface 11, a second surface 12, and a through hole 13. The first surface 11 and the second surface 12 are disposed opposite to each other, and the through hole 13 penetrates through the first surface 11 and the second surface 12. The area of the first surface 11 is smaller than the area of the second surface 12, and when the user wears the earcap 100, the first surface 11 is closer to the deep part of the ear canal than the second surface 12.
In some embodiments, referring to fig. 1 and 5, the second surface 12 is a curved surface, and the second surface 12 is recessed toward the through hole 13. That is, the distance between the area of the second surface 12 close to the through hole 13 and the first surface 11 is smaller than the distance between the area of the second surface 12 far from the through hole 13 and the first surface 11.
It should be noted that the ear cap body 10 is made of an elastic material, so that the ear cap body 10 has elasticity. That is, the ear cap body 10 has a certain deformation capability. Because the earcap body 10 has elasticity, earcap body 10 has certain deformability, and under the condition that earcap body 10 receives pressure, earcap body 10 can deform to make earcap 100 and user's duct better fit, thereby having improved the travelling comfort of wearing of earcap 100, also can reduce the noise entering people's ear in the outside air simultaneously, with this function of making an uproar falls that realizes earphone 300 (shown in fig. 7).
With continued reference to fig. 1, in some embodiments, the earcap body 10 can be made of a flexible material. Specifically, in some embodiments, the earcap body 10 is made of a flexible material having a hardness in the range of [1HA, 140HA ]. For example, the hardness of the ear cap body 10 may be any one of 1HA, 7HA, 15.5HA, 25HA, 30.2HA, 37.5HA, 45HA, 52HA, 64HA, 78HA, 86HA, 99HA, 112HA, 120HA, 130.4HA, 136HA, 140HA or any value between any adjacent values. For example, the ear cap body 10 can be made of silicone rubber having a hardness in the range of [1HA, 140HA ]. Because the silicon rubber with the hardness range between [1HA and 140HA ] is soft, the comfort level of the ear cap 100 worn in the auditory canal is improved, and the use experience of a user is enhanced. In other embodiments, the earcap body 10 is made of polyurethane foam, which is soft and has a certain sealing property, so that the noise reduction performance of the earcap 100 can be improved while the wearing comfort of the earcap 100 is improved. Of course, the ear cap 100 can also be made of a flexible sealing material that can directly contact the skin, and is not limited thereto.
In some embodiments, the ear cap body 10 can withstand a pressure limit of at least 2 newtons, i.e., the ear cap body 10 can withstand a pressure limit of 2 newtons, 3 newtons, 4 newtons, and so forth. When the pressure limit that the ear cap body 10 can bear is 2 newtons, the ear cap body 10 is not broken under the extrusion of a force of 2 newtons or less; when the ear cap body 10 can withstand a pressure limit of 3 newtons, the ear cap body 10 does not break when pressed by a force of 3 newtons or less. If the pressure limit that the earcap body 10 can withstand is too small (e.g., less than 2 newtons), the earcap body 10 is easily broken by the ear canal when the user wears the earcap 100, resulting in the fluid portion 20 embedded in the earcap body 10 flowing out to contaminate the ear canal of the user. The earcap body 10 of the present application has a pressure limit of at least 2 newtons, and when the user wears the earcap 100, the earcap body 10 is not easily broken under the extrusion of the ear canal, so that on one hand, the service life of the earcap 100 can be prolonged, and on the other hand, the fluid portion 20 embedded in the earcap body 10 is prevented from flowing out, thereby improving the safety of the earcap 100.
Referring to fig. 2 and 3, each fluid portion 20 includes a fluid 21. Because the fluid 21 has fluidity and large plasticity of the shape, when different users wear the same earcap 100, the fluid 21 can flow under the extrusion of the ear canal to drive the earcap body 10 to deform, so that the shape of the earcap 100 is matched with the ear canal of the user wearing the earcap 100 at the moment. On the one hand, since the fluid 21 has fluidity and the fluid 21 can ensure that the pressures in all directions are equal, the fluid 21 can drive the ear cap body 10 to deform according to the shape of the ear canal of the user wearing the ear cap 100 at present, so that the ear cap 100 can fit the ear canal of the user wearing the ear cap 100 at present, thereby improving the comfort of the user wearing the ear cap 100. On the other hand, the fluid 21 has a higher specific acoustic impedance than air, and can reflect sound waves. When the user wears the earcap 100, the fluid 21 embedded in the fluid portion 20 of the earcap body 10 can reflect the sound waves, so as to reduce the external sound waves from entering the ear of the user, thereby improving the sound insulation and noise reduction effects of the earcap 100.
In some embodiments, the fluid 21 may be water, and in this case, if the ear cap body 10 is broken when the user wears the ear cap 100, the fluid 21 flows from the ear cap body 10 to the ear canal of the user, and since the fluid 21 is water, and the water is neither corrosive nor toxic, the fluid 21 will not harm the ear canal of the user, thereby improving the safety of the user wearing the ear cap 100. In other embodiments, the fluid 21 may be a mixture containing vaseline, and at this time, if the ear cap body 10 is broken when the user wears the ear cap 100, the fluid 21 flows from the ear cap body 10 to the ear canal of the user, because the fluid 21 is a mixture containing vaseline which can be absorbed by the human body and has a certain viscosity, the fluid 21 does not harm the ear canal of the user, and at the same time, the fluid 21 does not easily flow to the deep part of the ear canal to hurt the ear drum of the user, thereby improving the safety of wearing the ear cap 100 by the user.
With continued reference to fig. 2 and 3, in some embodiments, the boiling point of the fluid 21 is greater than or equal to 60 degrees celsius, i.e., the boiling point of the fluid 21 is not less than 60 degrees celsius. For example, the boiling point of the fluid 21 may be any one of 60 degrees celsius, 70 degrees celsius, 75.6 degrees celsius, 80 degrees celsius, 89.5 degrees celsius, 95 degrees celsius, 100 degrees celsius, 115 degrees celsius, 120 degrees celsius, 135 degrees celsius, 150 degrees celsius, or any value between any adjacent values. If the boiling point of the fluid 21 is too low, for example, below 60 degrees celsius, when the ear cap 100 is placed in a high temperature environment, such as a car being exposed to direct sunlight in summer, the fluid 21 reaches the boiling point after being exposed to direct sunlight, which may cause the ear cap 100 to crack. The boiling point of the fluid 21 in the present application is 60 degrees celsius or higher, which makes the ear cap 100 less prone to cracking even in a relatively high temperature environment, thereby prolonging the service life of the ear cap 100.
In some embodiments, the freezing point of fluid 21 is equal to or less than-20 degrees celsius, i.e., the freezing point of fluid 21 is no greater than-20 degrees celsius, and fluid 21 does not freeze in environments greater than-20 degrees celsius. For example, the freezing point of the fluid 21 may be any one of-20 degrees celsius, -25.5 degrees celsius, -30 degrees celsius, -35 degrees celsius, -37.5 degrees celsius, -40 degrees celsius, -45 degrees celsius, -50 degrees celsius, -60 degrees celsius, or any value between any adjacent values. If the freezing point of the fluid 21 is too high, for example, higher than-20 degrees celsius, when the ear cap 100 is placed in a low temperature environment, for example, outdoor temperature in the north, the fluid 21 will start to solidify, and once the fluid 21 solidifies into a solid, the fluid has no fluidity, and at this time, when the user wears the ear cap 100, the fluid 21 can not drive the ear cap body 10 to deform, and the ear cap 100 can not fit with the ear canal of the user wearing the ear cap 100. The freezing point of the fluid 21 is less than or equal to minus 20 ℃, so that the ear cap 100 is not easy to freeze even in a relatively low-temperature environment, and the service life of the ear cap 100 is prolonged.
It is noted that in some embodiments, the boiling point of fluid 21 is equal to or greater than 60 degrees celsius and the freezing point of fluid 21 is equal to or less than-20 degrees celsius. Because the boiling point of the fluid 21 is greater than or equal to 60 degrees centigrade and the fluid freezing point is less than or equal to minus 20 degrees centigrade, the ear cap 100 can be used in various temperature environments, and the ear cap 100 is not easy to break, thereby prolonging the service life of the ear cap 100.
Referring to fig. 2 and 3, in some embodiments, the total volume of all fluids 21 in the same ear cap 100 is in the range of [0.001ml, 20ml ]. For example, the total volume of all fluids 21 within the same ear cap 100 can be any one of 0.001ml, 0.007ml, 0.01ml, 0.025ml, 0.045ml, 0.051ml, 0.075ml, 0.1ml, 1.2ml, 3.7ml, 4.8ml, 6.2ml, 8.0ml, 10ml, 13.5ml, 15ml, 17ml, 19.1ml, 20ml or any value between any adjacent values. If the total volume of all the fluid 21 in the same ear cap 100 is too small, for example less than 0.001ml, the pressure generated by the fluid 21 is not enough to deform the ear cap body 10, so that the deformed shape of the ear cap body 10 does not match the auditory canal of the user wearing the ear cap 100 at that time. If the total volume of all of the fluids 21 in the same ear cap 100 is too large, e.g., greater than 20ml, the pressure generated by the fluids 21 can easily cause the ear cap body 10 to rupture. The total volume of all the fluids 21 in the same ear cap 100 of the present application is in the range of [0.001ml, 20ml ], so that the pressure generated by the fluids 21 is enough to drive the ear cap body 10 to deform, and at the same time, the ear cap body 10 is not easily broken.
Referring to fig. 2 and 3, in some embodiments, the fluid portion 20 may further include a wrapping layer 22. Specifically, fluid 21 is filled in the inside of envelope 22, and envelope 22 is deformed together with fluid 21 by an external force. On one hand, because the fluid 21 is filled in the wrapping layer 22, when the earcap body 10 is broken, the wrapping layer 22 can prevent the fluid 21 from flowing out, so that the ear of a person is protected; on the other hand, since the fluid portion 20 includes the wrapping layer 22, the fluid 21 is easily embedded in the ear cap body 10, so that the ear cap 100 is relatively simple to manufacture.
In some embodiments, the ear cap 100 includes a fluid portion 20. Specifically, referring to fig. 2, the ear cap 100 includes an annular fluid portion 20, the fluid portion 20 surrounding the through hole 13. Since an annular fluid portion 20 is disposed around the through hole 13, on one hand, the fluid portion 20 can drive the earcap body 10 to deform in all directions; on the other hand, the fluid portion 20 completely wraps the periphery of the through hole 13, reflects sound waves around the through hole 13, and reduces external sound waves entering human ears from the periphery of the through hole 13, so that the sound insulation and noise reduction effects of the earcap 100 are improved.
In some embodiments, the ear cap 100 includes a plurality of fluid portions 20. For example, the number of fluid portions 20 in the ear cap 100 can be 2, 3, 4, 5, etc. Specifically, referring to fig. 3, the ear cap 100 includes four fluid portions 20, and the four fluid portions 20 are uniformly distributed around the through hole 13. Because four fluid portions 20 surround through hole 13 evenly distributed, can drive when earcap body 10 produces deformation, reflect the sound wave, reduce external sound wave and get into the people's ear to this improves the syllable-dividing noise reduction effect of earcap 100.
It should be noted that, when the ear cap 100 includes a plurality of fluid portions 20, the volume of each fluid portion 20 may be equal, and since the volume of each fluid portion 20 is equal, the plurality of fluid portions 20 may be arranged in batch, which speeds up the manufacturing of the ear cap 100. Of course, the volumes of the fluid portions 20 may be different from each other, and the volume of the fluid portion 20 on the side where the amount of deformation of the ear cap 100 needs to be large is larger than the volume of the fluid portion 20 on the side where the amount of deformation needs to be small, which is not limited herein.
Referring to fig. 4, in some embodiments, the ear cap body 10 further includes a first sub-body 14 and a second sub-body 15, and the first surface 141 of the first sub-body 14 is formed with at least one first groove 142. The first surface 151 of the second sub-body 15 is provided with at least one second groove 152. The first sub-body 14 is combined with the second sub-body 15, the first surface 141 of the first sub-body 14 is attached to the first surface 151 of the second sub-body 15, the at least one first groove 142, the at least one second groove 152, and the at least one fluid portion 20 correspond to each other, and the at least one fluid portion 20 is accommodated in the corresponding first groove 142 and the corresponding second groove 152.
In one example, the first surface 141 of the first sub-body 14 defines a first groove 142, and the first surface 151 of the second sub-body 15 defines a second groove 152. Specifically, referring to fig. 4, the ear cap body 10 includes a first sub-body 14 and a second sub-body 15, the first sub-body 14 includes a first surface 141 and a second surface 143 (also referred to as a first surface 11) that are disposed opposite to each other, and the first surface 141 of the first sub-body 14 is closer to the second sub-body 15 than the second surface 143 of the first sub-body 14. The first surface 141 of the first sub-body 14 defines an annular first groove 142, and the first groove 142 is disposed around the through hole 13. The second sub-body 15 includes a first surface 151 and a second surface 153 opposite to each other, and the first surface 151 of the second sub-body 15 is closer to the first sub-body 14 than the second surface 153 of the second sub-body 15. The first surface 151 of the second sub-body 15 is provided with an annular second groove 152. When the first sub-body 14 is combined with the second sub-body 15, the first surface 141 of the first sub-body 14 is attached to the first surface 151 of the second sub-body 15, so that the first groove 142 and the second groove 152 form an annular receiving cavity for receiving the annular fluid portion 20, and the receiving cavity can receive the fluid portion 20 shown in fig. 2.
In another example, the first surface 141 of the first sub-body 14 may be provided with a plurality of first grooves 142, and the first surface 151 of the second sub-body 15 may be provided with a plurality of second grooves 152, so long as each first groove 142 corresponds to one second groove 152, so as to form a plurality of receiving cavities capable of receiving the corresponding fluid portion 20. The plurality of receiving cavities may be configured to receive a plurality of fluid sections 20 as shown in fig. 3.
It should be noted that, the connection manner of the first sub-body 14 and the second sub-body 15 may be gluing or clamping, and is not limited herein.
If the fluid portion 20 does not include the wrapping layer 22, the first groove 142 and the second groove 152 may be filled with the fluid 21, and the first surface 141 of the first sub-body 14 and the first surface 151 of the second sub-body 15 are attached to each other, so that the fluid portion 20 is embedded in the ear cap body 10. If the fluid portion 20 includes the wrapping layer 22, a portion of the fluid portion 20 can be received in the first groove 142, another portion of the fluid portion 20 can be received in the second groove, and the first surface 141 of the first sub-body 14 is attached to the first surface 151 of the second sub-body 15, so that the fluid portion 20 is embedded in the ear cap body 10.
Referring to fig. 5, in some embodiments, the earcap body 10 may further define at least one receiving hole 16, one receiving hole 16 corresponds to at least one fluid portion 20, and the fluid portion 20 is received in the corresponding receiving hole 16. The ear cap 100 further includes at least one sealing member 30 corresponding to the at least one receiving hole 16, the sealing member 30 extending into the corresponding receiving hole 16 to block the fluid portion 20 from flowing to the outside.
For example, the earcap body 10 defines a receiving hole 16, and the earcap 100 further includes a sealing member 30. Specifically, as shown in fig. 5, the earcap body 10 defines a receiving hole 16. The receiving hole 16 includes a first sub-receiving hole 161 and a second sub-receiving hole 162, the second sub-receiving hole 162 is closer to the through hole 13 than the first sub-receiving hole 161, and the second sub-receiving hole 162 is used for receiving the fluid portion 20. The ear cap 100 further includes a sealing member 30, the sealing member 30 corresponds to the first receiving hole 161, and after the sealing member 30 is inserted into the first receiving hole 161, the sealing member 30 can block the fluid portion 20 disposed in the second receiving hole 162 from flowing to the outside.
In this case, if the fluid portion 20 does not include the wrapping layer 22, the fluid 21 may be directly poured into the second sub-receiving hole 162 from the first sub-receiving hole 161, and after the fluid 21 fills the second sub-receiving hole 162, the sealing member 30 is inserted into the first sub-receiving hole 161, so that the fluid portion 20 is inserted into the ear cap body 10. If the fluid portion 20 includes the wrapping layer 22, the fluid portion 20 can be inserted into the second sub-receiving hole 162 from the first sub-receiving hole 161, and then the sealing member 30 can be inserted into the first sub-receiving hole 161, so that the fluid portion 20 is embedded in the ear cap body 10.
It should be noted that, a plurality of receiving holes 160 may be formed in the ear cap body 10, and the ear cap 100 may also include a plurality of sealing members 30, so long as each receiving hole 160 has one corresponding sealing member 30, and the sealing member 30 and the receiving hole 160 can form one receiving cavity for hermetically receiving the corresponding fluid portion 20.
