La câteva săptămâni după ce au apărut primele zvonuri despre deja lansatul iPhone 7, peste 200.000 de oameni au semnat o petiţie online implorând compania americană să nu renunţe la jack-ul de căşti. Gigantul din Cupertino a decis să nu asculte vocea mulţimii şi a lansat săptămâna trecută primul iPhone fără jack-ul standard de 3,5 mm. Decizia companiei este inedită și îndrăzneață, având în vedere că istoria acestui port legendar datează din secolul XIX.

The older brother of the 3.5 mm jack
The history of the headphone jack begins in 1800, when his older brother, the 6.35 mm jack was used by the operators of the telephone boards to connect the calls.You have certainly seen this process in vintage films: several dozen centralists with bored voices stand in front of a gigantic panel full of 6.35 millimeters jack, people call in the central and ask to be directed to a certain number and centralist.connect two ports with each other with the help of a jack jack cable.
The solid construction of the jack allowed the operators of telephone power stations to remove and quickly introduce a cable from one port to another without worrying that they will destroy the equipment.This connector is also known as "ring and sleep type", which is "peak, ring and sleeve", due to its design.
3.5 mm jack standard for audio equipment industry
In 1950, with the appearance of portable radios using transistor-based circuits, which had been invented three years before, the 3.5 millimeter jack was also popularized..
The radios used by transistors became the best -selling gadget used in telecommunications in history.In just ten years, from 1960 to 1970, over three billion such devices were sold.People could first listen to music, news and other radio programs anywhere, regardless of the corner of the world they were in.
Shortly after the appearance of these small radios, the headphone market began to grow and people were more and more used by the 3.5 mm jack.This concept was the precursor of the famous Walkman Sony who appeared in the 80s and became an iconic image for that decade.The 3.5 millimeter jack quickly became a standard for the entire industry producing audio equipment from Walkmani radios and later at CD Playere, MP3 Players and finally smartphones.
What is interesting is that no one in the entire industry has asked the problem to change the banal jack connector because it was much easier for consumers to buy new audio equipment without worrying that they would no longer be compatible with the headphones they already had.In short if you were buying a device that had audio output, your headphones will fit either about a walkman, PC, a smartphone or a chair from a transatlantic plane.In addition, the Jack connector was a durable, stable and reliable system what made his change as unnecessary as possible.
An almost perfect connector
During 100 years of history, the headphone jack suffered extremely few changes, the most important being the transition from mono to stereo sound output and later adding the microphone function.
If we take a look at the headphone jack it is very easy to understand why it was a universal choice for the entire audio equipment industry..The 3.5 millimeter jack is an almost perfect connector: from the fact that the tip design makes contact between the jack and a very stable port until you do not have to worry that you have put the cable upside down..All this provides flawless audio quality.
Neither Samsung Galaxy S8 will have jack for headphones
We do not know if Apple's decision to give up old 3.5 millimeters will be defining about the future of this remarkable technology.We know, however.
Most likely, other producers will want to use this time and the almost crazy courage of the company in Cupertino to develop their own technologies meant to provide consumers a better audio experience..
Many specialists say that the headphone jack will not die and in no case in the near future because there is too much "infrastructure", meaning active audio devices or on the production line, which are used by this type of connector.
In addition, it is difficult to say whether the public will prefer a system in which the type of headphone port is dictated by the device manufacturer who has audio output or we will prefer an industry standard to lightly walk our ports in the port anddevice in device without adapters.In the same sense, certain specialists claim that in the near future the headphones will disappear and that the wireless audio devices will be the new standard.
