Since the invention of mobile phones, communication has always been its primary function, but with the development of the times, mobile phones are getting smaller and smaller, and more and more functions. Subsequently, photographs, listening to songs, etc. have all joined in, becoming an indispensable function of mobile phones, especially the advent of the mobile Internet era. Internet access has become the most important function of mobile phones. Nowadays, if there is no network, mobile phones are basically useless.

 

More than a decade ago, MP3 was very popular at that time. Then, because of the rise of smart phones, listening to songs with mobile phones has become the first choice for people, and the MP3 era is gone forever. And in 2016, nearly a decade later, mobile phone manufacturers began to “kill” the earphone jack on the phone.

 

After canceling the headphone jack, we had to make a converter and it was easy to lose. In addition, it is impossible to listen to songs while charging.

 

Why does the phone cancel the earphone hole?

Although there have been many objections, the elimination of the earphone jack on the mobile phone has become a trend and cannot be stopped. At this time, consumers will be confused, why?

 

First of all, in order to optimize the internal structure of the phone, save space

 

In 2016, Apple officially canceled the 3.5mm headphone jack on the iPhone 7. By disassembling it, it will be found that after removing the 3.5mm headphone hole, it will make room for the mobile phone. After removing the 3.5mm headphone jack, Not only can the phone be thinner and lighter, but also free up space to improve the life of the phone.

 

Second, sound quality considerations

 

The first thing to admit is that canceling the headphone jack does not have a substantial improvement in the sound quality of the phone. The main change is from analog signal output to digital signal output.

 

The analog signal is the already processed signal, so the sound quality will have a certain loss after the output; while the digital signal is close to the original signal without complete processing, so the plasticity is stronger.

There may be another way to change the sound quality of mobile phones. Generally, mobile phone manufacturers put the headphone jack and speaker on the bottom of the phone, and there is also a charging port. After the headphone hole is removed, the two speakers can be set at the bottom left and right. This will make the experience better when watching videos.

 

In addition, the elimination of the 3.5mm headphone jack has improved the appearance of the mobile phone to a certain extent, and the future is not only the headphone jack. With the development trend of the full screen, there will be many settings that will disappear, such as the handset. Xiaomi canceled the earpiece on MIX and used bone conduction technology.
