Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of earphones, in particular to a liquid-proof assembly and earphone. BACKGROUND

[0002] TWS earphones are increasingly widely used in daily life, and are often used in rainy days and outdoor sports scenes. In order to prevent sweat, rainwater and the like from entering the earphone interior, causing short circuit, device corrosion and the like, and thus leading to earphone damage, the traditional technology is to install a waterproof net at the sound leakage hole of the earphone, but the damping of the waterproof net with a higher waterproof level is larger and the waterproof net is poorer in air permeability, so that the acoustic performance of the earphone is poorer. Moreover, the liquid is more likely to wash off the waterproof net, so that the waterproof net is more likely to penetrate into the earphone interior, and thus the liquid-proof performance of the earphone is poorer.

[0012] In one of the embodiments, the third liquid hole and the first liquid hole are located at opposite sides of the liquid-proof structure, respectively.

[0013] In one of the embodiments, two ends of the second liquid hole are communicated with the third liquid hole and the first liquid hole, respectively.

[0014] In one of the embodiments, the liquid-proof assembly further comprises an adhesive sheet, which is attached to the side of the liquid-proof structure where the first liquid hole is formed, and the adhesive sheet is formed with a position-avoiding hole communicated with the first liquid hole.

[0019] 1. After a small amount of liquid seeps into the sound leakage hole, the liquid will adhere to the inner wall of the liquid-proof cavity, and the liquid needs to pass through the liquid-proof cavity before it can act on the tuning net, so that the liquid is more difficult to act on the tuning net, i.e. the liquid is more difficult to act on the electronic components inside the earphone. Even if a small amount of liquid enters the liquid-proof cavity, the liquid in the liquid-proof cavity can be shaken out by shaking the earphone, so as to avoid the liquid flowing to the tuning net and the electronic components inside the earphone.

[0032] The above-mentioned earphone and liquid-proof assembly, when a small amount of liquid seeps into the sound leakage hole, the liquid will be attached to the inner wall of the liquid-proof cavity, and the liquid needs to pass through the liquid-proof cavity before acting on the tuning net, so that the liquid is more difficult to act on the tuning net, that is, the liquid is more difficult to act on the electronic components inside the earphone, even if a small amount of liquid enters the liquid-proof cavity, the liquid in the liquid-proof cavity can be shaken out by shaking the earphone, so as to avoid the liquid flowing to the tuning net and the electronic components inside the earphone. In this way, the liquid-proof performance of the liquid-proof assembly is better, and thus the liquid-proof performance of the earphone is better. Moreover, since the liquid-proof performance of the liquid-proof assembly is better, it is not necessary to use a waterproof net to seal the sound leakage hole, and it is not necessary to use a tuning net with poor air permeability to prevent water, so that the sound leakage effect of the sound leakage hole is better, and thus the acoustic performance of the earphone is better.

[0033] In order to better understand the technical solutions and beneficial effects of the application, the application will be further described in detail below in combination with specific embodiments:

[0034] As Figures 1 to 4As shown, an embodiment of the earphone 10 includes a liquid-proof assembly 100, which includes a liquid-proof structure 110. The liquid-proof structure 110 has a first liquid-proof hole 111, a second liquid-proof hole 112, and a third liquid-proof hole 113. The first liquid-proof hole 111, the second liquid-proof hole 112, and the third liquid-proof hole 113 are sequentially connected to form a liquid-proof cavity 110a. The first liquid-proof hole 111 and the third liquid-proof hole 113 are offset, that is, they are asymmetrically arranged. The side of the liquid-proof structure 110 with the first liquid-proof hole 111 is used to fit against the inner wall of the housing 200 so that the first liquid-proof hole 111 is used to communicate with the sound-venting hole 202 of the housing 200. The side of the liquid-proof structure 110 with the third liquid-proof hole 113 is designed to fit against the tuning mesh 300, so that the third liquid-proof hole 113 is correspondingly positioned with the tuning mesh 300, thereby allowing the tuning mesh 300 to adjust the sound. In one embodiment, the earphone 10 also includes a housing 200 and a tuning mesh 300. The housing 200 has a communicating mounting cavity 201 and a sound venting hole 202. The liquid-proof structure 110 is located inside the mounting cavity 201. The side of the liquid-proof structure 110 with the first liquid-proof hole 111 is fitted against the inner wall of the mounting cavity 201, that is, the side of the liquid-proof structure 110 with the first liquid-proof hole 111 is fitted against the inner wall of the housing 200, so that the first liquid-proof hole 111 and the sound venting hole 202 are correspondingly connected. The tuning mesh 300 is fitted against the side of the liquid-proof structure 110 with the third liquid-proof hole 113, so that the tuning mesh 300 is used to adjust the acoustic performance.

[0035] like Figure 4 As shown, in this embodiment, when a small amount of liquid seeps into the sound vent 202, the liquid adheres to the inner wall of the liquid-proof cavity 110a, resulting in liquid droplets hanging on the inner wall of the liquid-proof cavity 110a, thus preventing the liquid from contacting the tuning mesh 300. When there is a small amount of liquid in the liquid-proof cavity 110a, the liquid in the liquid-proof cavity 110a is discharged through the sound vent 202 by shaking the headphones 10, thereby preventing the liquid from flowing into the tuning mesh 300 and the electronic components inside the headphones 10. It can be understood that the liquid can be water, sweat, or other fluid.

[0036] The earphone 10 and the liquid-proof assembly 100 described above, when a small amount of liquid seeps into the sound leakage hole 202, the liquid will adhere to the inner wall of the liquid-proof cavity 110a, and the liquid needs to pass through the liquid-proof cavity 110a before it can act on the tuning net 300, so that the liquid is more difficult to act on the tuning net 300, that is, the liquid is more difficult to act on the electronic components inside the earphone 10. Even if a small amount of liquid enters the liquid-proof cavity 110a, the liquid in the liquid-proof cavity 110a can be shaken out by shaking the earphone 10, so as to avoid the liquid flowing to the tuning net 300 and the electronic components inside the earphone 10. In this way, the liquid-proof performance of the liquid-proof assembly 100 is better, and the liquid-proof performance of the earphone 10 is better. Moreover, since the liquid-proof performance of the liquid-proof assembly 100 is good, it is not necessary to use a waterproof net to seal the sound leakage hole 202, and it is not necessary to use a tuning net 300 with poor air permeability to prevent water, so that the sound leakage effect of the sound leakage hole 202 is good, and the acoustic performance of the earphone 10 is good.

[0037] As shown in Figure 4 one of the embodiments, the extension direction of the second liquid-proof hole 112 is parallel to the extension direction of the liquid-proof assembly 100, so that the length of the second liquid-proof hole 112 is longer, and the flow path of the liquid from the sound leakage hole 202 to the tuning net 300 is longer, thereby improving the liquid-proof effect of the liquid-proof assembly 100.

[0038] As shown in Figure 4 one of the embodiments, the extension direction of the third liquid-proof hole 113 and the extension direction of the second liquid-proof hole 112 form an angle, so that the flow rate of the liquid is buffered, and the contact of the liquid with the tuning net 300 and the electronic components inside the earphone 10 is inhibited, thereby improving the waterproof effect of the earphone 10, and also making the structure of the liquid-proof structure 110 more compact. In this embodiment, the extension direction of the third liquid-proof hole 113 is perpendicular to the extension direction of the second liquid-proof hole 112.

[0039] As shown in Figure 4 one of the embodiments, the extension direction of the first liquid-proof hole 111 and the extension direction of the second liquid-proof hole 112 form an angle, so that the flow rate of the liquid is buffered, and the contact of the liquid with the tuning net 300 and the electronic components inside the earphone 10 is inhibited, thereby improving the waterproof effect of the earphone 10, and also making the structure of the liquid-proof structure 110 more compact. In this embodiment, the extension direction of the first liquid-proof hole 111 is perpendicular to the extension direction of the second liquid-proof hole 112.

[0040] As shown in Figure 4As shown in the drawings, in one of the embodiments, the third liquid-proof hole 113 and the first liquid-proof hole 111 are respectively located on opposite sides of the liquid-proof structure 110. In this embodiment, the sound of the sound generating unit of the earphone 10 is sequentially discharged through the third liquid-proof hole 113, the second liquid-proof hole 112, the third liquid-proof hole 113, and the sound discharge hole 202. The sound discharge hole 202 is arranged on the edge of the shell 200. Since the third liquid-proof hole 113 and the first liquid-proof hole 111 are respectively located on opposite sides of the liquid-proof structure 110, when the liquid-proof structure 110 is attached to the inner wall of the mounting cavity 201, the third liquid-proof hole 113 is arranged opposite to the sound generating unit of the earphone 10, thereby improving the sound discharge effect of the earphone 10 and further improving the acoustic performance of the earphone 10.

[0041] As shown in the drawings, Figure 4 As shown in the drawings, in one of the embodiments, the two ends of the second liquid-proof hole 112 are respectively communicated with the third liquid-proof hole 113 and the first liquid-proof hole 111, so that the length of the second liquid-proof hole 112 is relatively long, thereby making the flow path of the liquid from the sound discharge hole 202 to the tuning mesh 300 relatively long, and further improving the liquid-proof effect of the liquid-proof assembly 100.

[0042] As shown in the drawings, Figure 4 and Figure 5 As shown in the drawings, in one of the embodiments, the liquid-proof assembly 100 further comprises an adhesive sheet 120, the adhesive sheet 120 is attached to the side of the liquid-proof structure 110 where the first liquid-proof hole 111 is formed, the adhesive sheet 120 is formed with a position-avoiding hole 121, the position-avoiding hole 121 is communicated with the first liquid-proof hole 111 in correspondence, so that the liquid-proof cavity 110a is communicated with the sound discharge hole 202 through the position-avoiding hole 121. In this embodiment, the side of the liquid-proof assembly 100 where the first liquid-proof hole 111 is formed is attached to the inner wall of the shell 200 through the adhesive sheet 120, that is, the side of the liquid-proof assembly 100 where the first liquid-proof hole 111 is formed is attached to the inner wall of the mounting cavity 201 through the adhesive sheet 120, thereby improving the efficiency of mounting the liquid-proof assembly 100 to the shell 200.

[0043] As shown in the drawings, Figure 5 As shown in the drawings, in one of the embodiments, the size of the position-avoiding hole 121 is greater than the size of the first liquid-proof hole 111, thereby reducing the difficulty of aligning the position-avoiding hole 121 with the first liquid-proof hole 111, and further improving the efficiency of attaching the adhesive sheet 120 to the liquid-proof structure 110.

[0044] As shown in the drawings, Figure 5 As shown in the drawings, in one of the embodiments, the position-avoiding hole 121 is a waist-shaped hole, thereby reducing the difficulty of aligning the position-avoiding hole 121 with the first liquid-proof hole 111, and further improving the efficiency of attaching the adhesive sheet 120 to the liquid-proof structure 110. In this embodiment, the extension direction of the position-avoiding hole 121 is parallel to the extension direction of the liquid-proof structure 110.

[0045] As shown in the drawings, Figure 6As shown, in one embodiment, a water storage tank 114 is also formed within the second liquid-proof hole 112. In this embodiment, when liquid flows to the water storage tank 114, it is stored within the water storage tank 114 to suppress liquid flow to the third liquid-proof hole 113, thereby suppressing liquid flow to electronic components and improving the waterproof performance of the earphone 10. Furthermore, the water storage tank 114 is located below the second liquid-proof hole 112.

[0046] like Figure 6 As shown, the liquid-resistant component 100 further includes a water-absorbing layer 130, which is installed inside the water storage tank 114. In this embodiment, when water flows into the water storage tank 114, the water-absorbing layer 130 locks in the water, preventing water from flowing out of the water storage tank 114 and improving the waterproof performance of the earphone 10.

[0047] However, when the amount of liquid that seeps into the anti-liquid cavity 110a reaches a certain level, the liquid will seep along the inner wall of the anti-liquid cavity 110a into the tuning mesh 300 and even electronic components. In addition, when the flow rate of the liquid that seeps into the anti-liquid cavity 110a is high, the liquid will also seep along the inner wall of the anti-liquid cavity 110a into the tuning mesh 300 and even electronic components.

[0048] Therefore, such as Figure 6 As shown, in one embodiment, the first liquid-proof hole 111, the second liquid-proof hole 112, and the third liquid-proof hole 113 are all threaded holes, giving the inner wall of the liquid-proof cavity 110a a protruding thread. This increases the area of ​​the inner wall of the liquid-proof cavity 110a, allowing more liquid droplets to adhere to it. Furthermore, the protruding thread can block liquid, reducing its flow rate. This makes it more difficult for liquid entering the liquid-proof cavity 110a to penetrate the tuning mesh 300 and electronic components, thus improving the waterproof performance of the earphone 10. In this embodiment, the protruding thread can also block some dust in the air and cause the dust to adhere to the thread, inhibiting dust from clogging the tuning mesh 300. This maintains the high breathability of the tuning mesh 300, thereby improving the acoustic performance of the earphone 10. In addition, the dust adhering to the thread can also absorb liquid entering the liquid-proof cavity 110a, making it more difficult for liquid to contact the tuning mesh 300 and electronic components, thus improving the waterproof performance of the earphone 10.

[0049] However, since the extension direction of the second liquid-proof hole 112 is at an angle to the extension direction of the first liquid-proof hole 111, and the extension direction of the second liquid-proof hole 112 is at an angle to the extension direction of the third liquid-proof hole 113, the second liquid-proof hole 112 cannot be a threaded hole.

[0050] To make the second liquid-proof hole 112 a threaded hole, such as Figure 6As shown, in one embodiment, the second liquid-proof hole 112 penetrates the liquid-proof structure 110. The liquid-proof assembly 100 also includes two elastic sealing plugs 140, which are located at both ends of the second liquid-proof hole 112, and are elastically sleeved with the liquid-proof structure 110. The two elastic sealing plugs 140 are staggered from the first liquid-proof hole 111 and the second liquid-proof hole 112.

[0051] like Figure 6 As shown, in this embodiment, since the two elastic sealing plugs 140 are respectively located at both ends of the second liquid-proof hole 112 and elastically sleeved with the liquid-proof structure 110, that is, the two elastic sealing plugs 140 are respectively located at both ends of the second liquid-proof hole 112 and elastically abut against the liquid-proof structure 110, the two elastic sealing plugs 140 block both ends of the second liquid-proof hole 112, preventing the two ends of the second liquid-proof hole 112 from opening, thereby preventing liquid entering the liquid-proof cavity 110a from flowing out from both ends of the second liquid-proof hole 112, thus ensuring the waterproof effect of the liquid-proof structure 110. It can be understood that each elastic sealing plug 140 can be a silicone structure, a rubber structure, or other existing elastic structures.

[0052] It is understandable that when dust accumulates on the threads of the second liquid-proof hole 112 to a certain extent, the dust will reduce the unobstructed flow of the sound-venting hole 202, thereby reducing the sound-venting effect and thus reducing the acoustic performance of the headphones 10. Moreover, when water adheres to the threads of the second liquid-proof hole 112 for a long time, it will form water stains, which will also reduce the sound-venting effect and thus reduce the acoustic performance of the headphones 10.

[0053] To clean dust and water stains from the threads of the second liquid-proof hole 112, such as Figure 6 As shown, in one embodiment, each elastic sealing plug 140 is threaded into the second liquid-proof hole 112, and the length of one of the elastic sealing plugs 140 is greater than the length of the second liquid-proof hole 112.

[0054] like Figure 6As shown, in the present embodiment, when the dust attached on the thread has a great influence on the acoustic performance of the earphone 10, the elastic sealing plug 140 with a shorter length is rotated out, and the elastic sealing plug 140 with a longer length is rotated in, so that the outer thread of the elastic sealing plug 140 with a longer length penetrates into the second liquid-proof hole 112 along the inner thread of the second liquid-proof hole 112, and the dust and water stains on the inner thread of the second liquid-proof hole 112 are moved out of the second liquid-proof hole 112 by the outer thread of the elastic sealing plug 140 with a longer length. After the elastic sealing plug 140 with a longer length penetrates into the second liquid-proof hole 112, most of the dust and water stains on the inner thread of the second liquid-proof hole 112 are brought out of the second liquid-proof hole 112, and then the dust and water stains brought out by the elastic sealing plug 140 with a longer length are cleaned, so that the effect of cleaning the dust and water stains is achieved. In order to improve the cleaning effect of the dust and water stains, the corresponding elastic sealing plug 140 can be reciprocated through the second liquid-proof hole 112 for multiple times, so that as much dust and water stains as possible are brought into the second liquid-proof hole 112. In this way, the elastic sealing plug 140 can clean the dust and water stains by rotation, which reduces the adverse influence of the dust and water stains on the sound leakage effect, and further reduces the adverse influence of the dust and water stains on the acoustic performance of the earphone 10.

[0055] As shown, Figure 6 Further, as shown, after the cleaning of the dust and water stains is completed, the two elastic sealing plugs 140 are reset, i.e., the two elastic sealing plugs 140 are respectively located in the two ends of the second liquid-proof hole 112 and elastically sleeved with the liquid-proof structure 110, and the two elastic sealing plugs 140 are arranged staggered with the first liquid-proof hole 111 and the third liquid-proof hole 113.

[0056] However, in order to improve the sealing effect of the elastic sealing plug 140, the surface of the elastic sealing plug 140 is relatively smooth, which makes it difficult for the dust and water stains to be attached on the elastic sealing plug 140, and further the cleaning effect of the elastic sealing plug 140 on the dust and water stains in the second liquid-proof hole 112 needs to be improved.

[0057] As shown, Figure 6As shown, to improve the cleaning effect of the elastic sealing plug 140, in one embodiment, the liquid-proof assembly 100 further includes two cotton layers 150, each less than 0.1 mm thick, which are respectively wound around the external threads of the two elastic sealing plugs 140. In this embodiment, because each elastic sealing plug 140 is elastic and each cotton layer 150 is relatively thin, each elastic sealing plug 140 still maintains a sealing effect after being wrapped with the corresponding cotton layer 150. When cleaning dust and water stains, as the corresponding elastic sealing plug 140 rotates, the corresponding cotton layer 150 wraps around the dust and water stains, causing the cotton layer 150 to carry the dust and water stains away from the second liquid-proof hole 112, thereby improving the cleaning effect of the elastic sealing plug 140 on dust and water stains and resulting in better acoustic performance of the earphone 10. Moreover, since each cotton layer 150 has a water-absorbing effect, it inhibits water from seeping into the tuning mesh 300 and electronic components, improving the waterproof performance of the earphone 10.

[0058] It is understandable that, since the elastic sealing plug 140 is an elastic structure, the part of the elastic sealing plug 140 extending out of the second liquid-proof hole 112 is relatively easy to bend, which makes it more difficult to rotate the elastic sealing plug 140.

[0059] To prevent the portion of the elastic sealing plug 140 extending out of the second liquid-proof hole 112 from bending, and thus reduce the difficulty of rotating the elastic sealing plug 140, such as... ​ As shown, in one embodiment, the liquid-proof assembly 100 further includes two rigid fixing posts 160, and two elastic sealing plugs 140 are respectively covered and connected to the two rigid fixing posts 160. This avoids bending of the elastic sealing plugs 140, reduces the difficulty of the elastic sealing plugs 140, improves the smoothness of the rotation of the elastic sealing plugs 140, and thus improves the smoothness of cleaning dust and water stains, thereby improving the efficiency of cleaning dust and water stains.

[0060] Compared with the prior art, the present invention has at least the following advantages:

[0061] 1. When a small amount of liquid seeps into the sound vent 202, the liquid will adhere to the inner wall of the liquid-proof cavity 110a. The liquid needs to pass through the liquid-proof cavity 110a before it can act on the tuning mesh 300, making it difficult for the liquid to act on the tuning mesh 300. This also makes it difficult for the liquid to act on the electronic components inside the earphone 10. Even if a small amount of liquid enters the liquid-proof cavity 110a, it can be shaken out by shaking the earphone 10, thus preventing the liquid from flowing into the tuning mesh 300 and the electronic components inside the earphone 10. In this way, the liquid-proof component 100 has good liquid-proof performance, which in turn makes the earphone 10 have good liquid-proof performance.

[0062] 2. Because the liquid-proof component 100 has good liquid-proof performance, there is no need to use a waterproof mesh to seal the sound leakage hole 202, and there is no need to use a tuning mesh 300 with poor air permeability for waterproofing. This makes the sound leakage effect of the sound leakage hole 202 better, and thus makes the acoustic performance of the earphone 10 better.
