Even after using it every day, you did not know their secrets before!

We live in a modern age of technology, where everything has been replaced by modern tech. The wristwatch not only shows the time, but also has some great high-tech features that could not have been imagined just a few years ago. But there are small secrets behind many of the techs we use today that many did not know before. For example, is there a small black cylinder near the charger pin of the laptop? How do smartphones tremble? Or why there are two spots on the headphone pin and three spots on the pin?

Well, this article will answer some of the questions that you are using every day, but did not know the secrets behind them before! So let's find out today.

Striped headphone jack.

It is difficult to find someone who does not use headphones daily. However, many companies have removed the headphone jack from the phone to replace the headphone jack system. But still everyone uses a jack with a long pin. And phone companies have removed the jack support directly from their phones, but provide a special cable that allows regular headphone jacks to be inserted.

If you have been using headphones for a long time, then you must have noticed that the headphone mini jack has stripes. Some headphone jacks have two stripes, some have three stripes and many earlier headphone jacks had only one spot! You just put Jack on the phone and start listening to music, but have you ever wondered what these stripes are for?

Well, these striped spots are basically made of plastic, with these spots separating the connections to the headphone jack. Only 1 spot on the pin of the headphone means that the headphone provides mono sound, which means that the same audio is input to the two speakers in the headphone. Two striped means the headphone supports stereo sound, while the right speaker and left speaker of the headphone have two different speakers!

Most of today's headphones have 03 striped spots, these headphones support stereo audio and it also has microphone support, using these headphones you can talk on the phone and record audio! - It's very simple, isn't it? But many may not know it!

What is it like a black cylinder near a laptop charger pin?

Not only laptop chargers but also previous USB cables and phone chargers could have seen these things. Things like a black cylinder are attached to the connector of the charger, have you ever wondered why it is attached? Or in its real work or what?

The name of the black cylinder enclosed in plastic is   Ferrite Bead - it basically helps to block high frequency noise electric noise coming from all devices. So that there is no electromagnetic interference between one device and another.

Your laptop charger or phone charger is designed to recharge your device, but it's difficult if that cable starts capturing a different signal noise. Professional Studio Mike's USB cable is also fitted with these ferrite beads so that only audio is recorded during the recording, so that the surrounding wireless or electronic circuit noise is not captured. A circuit is actually a loop of various parts that allows electricity to flow through the current. Many times during this current flow an electromagnetic field is created around it, and many times that electromagnetic field can receive your cable.

Ferrite beads act like a resistor, meaning it absorbs electric energy and converts it into heat. This means that the cable receives different signals, filters them into ferrite beads, releases them into heat and delivers them to the correct current charger connector! Things got a little technical though, but now you know what that black cylinder does!

Infrared code .

Sounds like a lot of high-tech stuff, doesn't it? Sounds like a lot of secret Russian Army communication code, right? In fact, using this code, your TV and TV remote talk to each other. Not just TVs, but devices that have remote controls that use infrared code to talk to it.

You may turn on the TV comfortably by pressing the remote and then take control, but you may not know that the TV and the remote are talking to each other using this special code. Most remote controls, as well as yours   , work on infrared radiation . When you look at the top of your remote, you will see an LED bulb, from which these infrared radio waves emanate. The remote in your hand is usually a transmitter and a receiver attached to the TV or other device, which receives the infrared signal from the remote.

There are at least 20 buttons on your TV remote, so the remote control must have the ability to generate a different signal when each of these buttons is pressed and the TV understands it. The remote control also works in binary like a computer. When you press a button on the remote it sends an on or off signal, where on means 1 and off means 0. The remote sends a few pulses together and sends the pulse in a different way to each button.

How is the vibration on the phone?

Suppose one of the three wings of your table fan is broken. In this case, if you want to turn on the table fan, it will vibrate violently and the fan may break or break after cutting. As a result of breaking a fan, the fan no longer maintains balance!

Unbalanced motor but may not always be useless. There are many unbalanced motors in your daily used cell phone. These motors tend to be slightly larger in size than pencil faces. And a load of semi-circular shape is applied to the face of the motor, resulting in vibration due to its imbalance when the motor rotates too hard.

Yes, every time a call comes to your phone, a new text message comes to your phone, or whenever the phone vibrates for whatever reason, it comes from that unbalanced motor in the phone! What? Isn't that funny? I can say for sure that not many people knew it!

What does the strange code of the mobile charger actually mean?

When you use a mobile phone every day, you must use a mobile charger every day! If you look closely at the mobile charger, you will see that all the codes and symbols have been drawn before. What do these mean? Ever questioned yourself? Well, let's answer!

Almost all chargers have a kind of certification mark "CE" mark, which means you can use this charger without any problem and it is tested. This means it will not harm your health, safety, or the environment. A product is marked "CE" only after passing all the quality tests.

If you look further into the charger, you will see that it has a small home sign, which means that this device is only suitable for home use! You will then see that the charger has a double square sign, which means that your device has double insulation protection which means you are perfectly safe from getting electric shock from this device.

You will see again that the cross sign above the recycle sign is dead before the charger, this means that the device has to be recycled properly. Just don't throw it in the recycle trace, it can harm the environment. Moreover, the "V" is found on your charger, indicating which country it is suitable for. If the "IV" sign means it is for the US, if the "V" sign can be used in Europe!

So these were some of the big and small secrets of everyday things that you may have never thought of before! If you want to add more to this list, you can comment below. Be sure to let us know below if you have been surprised to know any secrets!
