Charging socket What is the waterproof principle of the headphone jack?

In the interface position, the use of conductive ability, waterproof ability is relatively strong materials for sealing, high-quality workmanship to avoid moisture in, so that when there is water, moisture will not enter the inside of the mobile phone, conductivity.

The strong interface material also does not interfere with daily use.

Because the material used in these areas is relatively low-density, it is not easy for water to enter, but if the pressure is high enough, it is not completely waterproof.

It is to separate the earphone jack, charging port and the inside of the fuselage, and then maintain a zero potential state when there is no load. If we take a closer look at the headphone jack and the Type-C port, we can find that in fact, there are only a few contacts between the male and female ports, and there are no direct gaps and cavities extending into the fuselage. ‍‍

The headphone jack is an independent module, except for the contact point and the mobile phone motherboard link are sealed, and then glued to the hole made in the mobile phone frame. The glue is waterproof and airtight, so it is waterproof.

In fact, the so-called waterproofing is not completely waterproof, but it is just that the water cannot easily enter, such as a waterproof mesh, normal water droplets cannot flow in, but if the pressure is applied to a certain extent, it can still go in.

The hole is too small, and the pressure inside forms a confined space, and the atmospheric pressure cannot enter.

The charging socket and near the earphone jack are sealed with glue to prevent water from entering the phone through the gaps in these places.

The principle is actually very simple, that is, to separate the headphone jack and, charging port and the inside of the fuselage, and then maintain a zero potential state when there is no load. ‍‍

It should be sealed at the edges, there are gaps in general, and the waterproof ones are specially treated with waterproof materials for these positions.

The use of nano-coating waterproof technology, the so-called waterproof, is not completely waterproof, just so that the water can not easily enter, such as a waterproof mesh, normal water droplets can not flow into,.

It should be sealed around the edges, generally with gaps, and these locations should be specially treated with waterproof materials.

To put it bluntly, the headphone jack is an independent module, except for the contact point and the mobile phone motherboard link are sealed, and then glued to the hole made in the mobile phone frame. The glue is waterproof and airtight, so it is waterproof. The speaker is complex,Generally after a layer of airtightness to form a confined space,There is air in the air hole after the mobile phone comes into contact with water,Because the interior is sealed,The air can't come out,The air can't get in if the water is blocked,So the water is released,The waterproof of the speaker is not sure what others say,But it is indeed feasible。

The headphones can be seen by disassembling the device.

It's sealed with a special material.

Good if you don't get into the water, I used Z1 to go into the water n times.

No, depending on the material of the phone, it may seep through the case, so it is best to wrap it all.

In this case, it is recommended to judge the physical mobile phone after on-site inspection. In order to understand and solve the problems of the mobile phone in a more targeted manner, it is recommended to send the mobile phone to the nearest service center for testing, and the service center will determine the specific problems, accessories, and whether the mobile phone is within the scope of repair and maintenance according to the test results**.

Personally, I think I should use a strong waterproof glue to smear all the headphone holes, and generally speaking, it will not leak.

Note: If there is a water leak, it means that there is a problem with the glue or construction method you are using.

The part of the earphone cable is made of water discharge material, and the earphone will not be burnt, but the density of the water is not large, and it will not flow into it from the small gap on the earphone, but it will also affect the quality of listening. If it's broken, I'll buy a simple orange, and I don't have much money.

Because the headphone jack has also been treated with a waterproof structure, water cannot run into the inside of the phone. In the past, Sony's waterproof mobile phones had rubber stoppers, but now they are all used. - Source: Wanken smartphone IP waterproof level testing device, detector leak detector leak tester.

Hello dear Samsung users:

According to your description, the Samsung Galaxy S5 is IP67 dust and water resistant for your safety.

IP67 dustproof and waterproof: This equipment has IP67 dustproof and waterproof functions as defined in the IEC60529 international standard. Please note that this phone is not designed for surface or underwater operations, and only has the ability to withstand dust and water in certain environments as required by the IP67 rating.

Please strictly follow the instructions for dust and water resistance in the manual of this equipment, otherwise the user shall be responsible for the damage to the equipment caused by this.

Samsung knows that we will provide you with high-quality solutions and answer your questions attentively, and hope to get your satisfactory evaluation.

The headphone jack of the Samsung S5 is closed and blocked, leaving only the contacts connected to the headphones and the main components such as the motherboard are isolated independently So even if the headphone jack gets water, the water will not enter the inside of the phone and damage the main components such as the motherboard There is also a possibility that the inside of the headphone jack has been attached with a nano waterproof coating So it will also have a waterproof effect In addition, not all headphone jacks are not afraid of water Unless a specific waterproof phone or device is likely to be waterproof Landlord, don't you try every one!! Even if the device is not damaged, it is likely to cause poor contact with the headphone jack, resulting in the headphones and other headphones cannot be used normally, remember!

There are currently two types of waterproof solutions for mobile phone headphone jacks: The liquid silicone injection process makes the headphone jack plug-in coated with waterproof glue into a jack with waterproof function; There is also a more extreme way, which cancels the headphone jack of the mobile phone and integrates the headphone function in the Type-C interface. However, the idea is also to use CL-26AB liquid silicone gel water thermal bonding silicone rubber sealing ring to stick together with Type-C.

There is a sealing rubber ring inside, and the headphone jack is short-circuited and not in the way.

Hello, you can know how people did it when you buy this patent, thank you.
