Recently, news spread in the industry that Apple's next generation iPhone will eliminate the traditional 3.5mm headphone interface, which has suddenly become a hot topic. There are also various opinions on the reason for canceling the headphone interface, with the most concentrated one being the use of an integrated lighting interface to continue reducing body thickness, making the iPhone 7 the thinnest iPhone in history. Today, the author will take you to analyze whether it is really possible for Apple to cancel the headphone jack?

Apple has always been known for being unique and pursuing perfection, and streamlining product interfaces is not the first time. The future direction of Apple will also be the integration of multi interface functions, minimizing the use of open interfaces on Apple devices and centralizing the functions of various interfaces in one interface.

This has already been a precedent on Apple's new MacBook. On the newly released Apple MacBook in the first half of this year, many netizens were also surprised to discover the fact that it only has a type-c interface besides the headphone jack.

The full name of type-C is USB type-C interface, which is a new form of USB interface. It has been nearly a year since its release, accompanied by the latest USB 3.1 standard. After all, it is just a USB interface. In terms of functionality, due to the improvement of USB 3.1 technical specifications, the actual transmission performance of the new interface has also been significantly improved. The theoretical maximum transmission speed can reach 5Gbps, and when converted to our commonly used MB/s, it is 625MB/s, a very surprising number! At the same time, the power of the type-c has reached an astonishing 100W, and based on the current mainstream laptop's 65W power supply, it can fully serve as a power interface to power the device.

A single interface can serve as a USB, video output, and power interface, and the emergence of the type-c interface seems to have pushed Apple to the pinnacle. Although this interface is not the first release of an Apple product, it must be admitted that being exposed to Apple's light can quickly become well-known, and Apple does have the ability to further promote a standard interface.

IPhone waterproof requirements

For a long time, it seems that the iPhone has not intersected with waterproof and anti drop features. The "delicacy" of the iPhone has always been criticized by users, but on the latest Apple flagship iPhone 6s, many people have found that there are certain waterproof measures in place, and even foreign netizens have conducted experiments. After soaking the 6s in water for 30 minutes, they can still be used normally, which is enough to show Apple's efforts in waterproof performance.

The waterproofing of mobile phones is actually to prevent water from entering the interior of the phone, and the earphone jack and speaker hole of the phone are the key points of waterproofing. Previously, the United States Patent and Trademark Office published a patent application file submitted by Apple, which is basically a method to actively drain water trapped in a narrow, confined space. The patent also shows that this waterproof technology is equipped with a sensing device in the earphone hole. When water flow is detected entering the earphone hole, the device will use electrode changes to discharge water from the earphone hole. The drainage method of the speaker hole incorporates a similar mechanism, but the difference is that the speaker uses ultrasonic vibration to discharge water.

From this, it can be seen that Apple does want to focus more on the waterproof performance of its phones. There have been rumors before that the iPhone 7 may support waterproof functionality. Given that the aforementioned patented technology is still in the conceptual stage, it is better to simply reduce the number of headphone interfaces, which may mean that the waterproof performance is easier to meet Apple's requirements, while also reducing production costs.

Powerful Lighting Interface

The predecessor of Lighting was Apple's unique 30pin interface. Although the 30pin interface was relatively large, it had functions such as charging, high-speed data transmission, audio output, and console. During this nine year evolution, Apple gradually added high-definition video output, photo OTG, and other functions, greatly surpassing the micro USB interface. However, traditional 30-pin interfaces are gradually falling behind, with the main drawback being that they occupy a large amount of space.
