The mobile phone cancels the 3.5mm earphone hole, and the earphone hole is naturally reduced on the fuselage, so the designer will get more design space, which can fully show the design aesthetics of the mobile phone. Because the diameter of the 3.5 mm headphone jack is larger, canceling the 3.5 mm headphone jack can bring more possibilities for making thinner and thinner mobile phones.
Moreover, if the phone cancels the 3.5mm headphone jack, it can save some space for the internal structure of the phone. The saved space can be used to increase the battery capacity and improve the battery life, and it can also be used to make the size of the mobile phone thinner, so that the smart phone can pursue the "slimming plan" while pursuing the big screen.
Extended data:
With the increasingly rich functions of mobile phones, the increase of mobile phone hardware will occupy more and more space in mobile phones, and the value of the internal space of mobile phones is also increasing. However, 3.5mm is an optional function, which will occupy the function of the mobile phone.
Giving up the 3.5 mm headphone jack can make room for the hardware with new functions. For example, the popular off-screen fingerprint technology and three-dimensional structured light all need new hardware to occupy the internal space of mobile phones. Many manufacturers will choose the latter and give up the earphone interface to add new functions.
There are many alternative products for headphone jack. For example, the quality of today's Bluetooth headphones is also very good, not worse than wired headphones. Of course, manufacturers generally provide 3.5mm headphone adapters or directly provide headphones with the same type-C interface as the power interface. Therefore, the advantages of canceling the 3.5mm headphone jack outweigh the disadvantages.
