Apple's newly released AirPods headset and iPhone
On September 8, Apple held the 2016 Autumn New Product Launch Conference in San Francisco as scheduled and launched the new iPhone 7 and Apple Watch 2. One of the most important updates about the new iPhone is the official cancellation of the 3.5mm headphone jack that has existed for 50 years. Regarding the possible impact of this change, Lei Feng first interviewed a practitioner, He Tianyang, the founder of the BESOUND headset, to learn some of his views.
As one of the earliest entrepreneurs to start Lightning interface headsets in China, the first Lightning interface headset "Thunder" of the BESOUND team has completed the research and development of key technologies and is currently in the stage of Apple's certification review.
Lightning Headphones Thunder
He Tianyang, the founder of the company, said: "BESOUND was established in late 2015 and belongs to the earliest batch of Lightning headphones in China. At that time, there was no rumors that the iPhone would cancel the 3.5mm interface. We rely entirely on our own inferences and rely on a It was all together and it was all the way to go today."
Regarding why BESOUND can see the rise of Lightning in a forward-looking manner, and what key advantages Lightning has over 3.5mm headsets, He Tianyang himself published in “ Lei Feng Net†(search for "Lei Feng Net" public number) "Maybe, soon you I will forget that the iPhone used to have an interface called the 3.5mm headphone port.
The article mentioned that nearly half a year of 3.5mm interface has become a stumbling block for the mobile phone industry to continue to advance in both volume and water resistance. However, in He Tianyang’s view, the key advantage of Lightning headsets is actually openness and freedom . This is also the heart that he has been adhering to since his establishment.
Specifically, due to the existence of the pure digital interface Lightning, the earphone manufacturer who wants to adapt to the iPhone 7 has to shift from the digital signal that has been completed by Apple within the mobile phone to the analog signal conversion operation (ie, digital-to-analog conversion). To the outside of the phone, that is, Lightning headphones to do. This not only brings about structural simplification for the mobile phone itself, avoids complex electromagnetic interference inside the mobile phone for audio decoding, but also provides developers with a broader space for play.
On the one hand, He Tianyang stated: "For headset manufacturers, Lightning headset is no longer just a passive signal receiver, but a signal producer that can be freely customized, a 'player' that can be flexibly adjusted . " Because all digital-to-analog conversion and sound quality tuning work is opened up through Lightning, manufacturers have full freedom, they can increase their low frequencies, suppress high frequencies, and produce a wide variety of output sounds according to their own style . It is even possible to open the adjustment switch to the headphone user, which is adjusted by the user.
On the other hand, Lightning also has a wider range of expansion capabilities for more potential development. He Tianyang said: "In addition to the once-superior active noise reduction function in the era of civilian-oriented digital audio, Lightning can also be combined with power supply systems to produce derivative components such as back-grid batteries. In addition, if combined with accelerometers, etc. A series of sensors allows the external device to track the user's head movement in both direction and speed. Lightning headsets will have the opportunity to implement multiple applications in the AR/VR field."
He Tianyang responded to questions of general concern about sound quality and power consumption :
“Lightning sound quality is not necessarily better than 3.5mm traditional headphones. Just as mentioned earlier, the actual sound quality performance depends entirely on the adjustment of the headset manufacturer and the user’s choice.â€
In addition, the fear that the digital-to-analog conversion function is open to third parties that may increase power consumption is also redundant. He Tianyang said:
"Because all genuine Lightning headsets certified by MFi, according to Apple's requirements will limit the operating current below 50mA, and the iPhone's standard charger output specifications are 5V 1A, compared to the largest 50nm Lightning headphones is the order of magnitude No need to worry about power consumption."
Referring to "openness," He Tianyang stated that they do not only want to use Headphone products with Lightning interface, but also do a digital audio tuning platform for traditional headset manufacturers .
He Tianyang believes that due to various advantages of the Lightning interface, between 2017 and 2018, all major mobile phone manufacturers will certainly abandon the 3.5mm traditional interface like the iPhone 7, and step into the era of digital audio. Of course, Android devices will choose USB-C. Although there will be a certain period of transition, Lightning and USB-C adapters will certainly have a rapid growth phase, but he is certain that the future must be digital.
Therefore, from the perspective of future development, the difficulties faced by traditional headset manufacturers can be imagined. It is based on such considerations. In addition to BESOUND, He Tianyang’s team has also established a digital audio technology platform called Lian Ye Technology. Through this platform, traditional headset manufacturers can receive BESOUND technical support in digital audio tuning to develop their own digital interface headsets.
He Tianyang said: “The current vocal technology used by traditional headset manufacturers such as moving coils and moving irons is also applicable in the era of digital headphones. However, the processing and tuning of front-end digital signals to analog signals is not possible for traditional headset manufacturers. Actually it's equivalent to being a player, not a headset, so I wanted to create an open platform and use BESOUND's digital tuning technology to help traditional vendors quickly catch up with the industry."
When asked about the emergence of the Lightning audio interface, He Tianyang did not hesitate to answer: “Opportunity†when it comes to opportunities or challenges for the headset industry. He said: "With survival of the fittest, Lightning is a progress and progress is an opportunity. BESOUND is currently only doing Lightning interface products. We have also considered that this may lose a certain number of potential consumers in the short term, but I believe that no matter what company Or personal, focusing on one thing is the most important thing."
