Headphone holes are gone, why iQOO still spare no effort to create an audio experience?

Barret SEP 02,2021

August 17, iQOO cell phones officially released a new iQOO 8 series of cell phones. As the iteration of iQOO digital flagship series, iQOO 8 series ushered in a significant upgrade in performance, photography and other aspects: like Snapdragon 888/Plus + LPDDR5 + UFS3.1, 2K + E5 + OLED screen, large bottom gimbal main camera and other cutting-edge configurations have been adopted. In addition to these bright configurations, in some details configuration iQOO 8 series also did not ignore, such as cell phone audio.

In the cell phone audio, iQOO 8 series in addition to dual speakers also brings a unique full-link sound quality improvement technology, both external playback or headphone listening experience is very good. Looking at the entire cell phone market, in the manufacturers are focusing on strengthening cell phone performance / photo capabilities, like iQOO insist on creating cell phone audio brands have been few. Also as the title says: headphone jack are gone, why iQOO still spare no effort to build audio experience? The next small just talk to you.

Mobile audio talk: from "listen to a loud" to mobile HiFi to the decline

Before we start discussing related topics, Xiaogang wants to sell a little, and talk about the development of mobile audio.

Feature phone era, users want to get an excellent music listening experience, can rely on only the Walkman. And the development of the Walkman also exists in turnover, from cassette players to CD players to slightly earlier mp3 players, its sound quality performance has also been further enhanced: from high bottom noise + low resolution analog music development to a comprehensive upgrade of digital music, and then to the late lossless music format, the device size is getting smaller and smaller, but by the higher and higher supported music formats, sound quality is also getting better and better. The later development of digital music also laid a solid foundation for the next cell phone audio development.

In contrast, early cell phones tended to focus on the battery as their development focused on call functionality, and were often equipped with a single speaker with low volume. In the era of GSM cell phones, Siemens launched the first cell phone with expanded memory/MP3 player - SL45 (Siemens 6688 in China), which allowed users to transfer and store MP3 songs by connecting the phone to a computer.

With the help of the former, the Motorola ROKR E1, released in 2005, successfully opened the door to music phones in the feature phone era, while the latter laid a strong foundation for the audio performance of iPhone/iPad products. The latter laid a strong foundation for the audio performance of iPhone/iPad products.

Since then, with the growing digital music resources and the aversion to large CD players, people are increasingly inclined to store music in their cell phones. While the development of digital music was in full swing, the feature phone & music phone at that time only solved the problem of "can you store music", even though the later focused more on the optimization of operation, interface, appearance, etc., as the core of the audio performance is still in the "listen to a sound "stage, users with requirements for sound quality often choose a cell phone + a form of MP3. The combination of good sound quality and a highly portable cell phone can be said to be the goal of the manufacturers pursued at that time.

When cell phones entered the smartphone era, the sound quality of Apple iPhone was considered the best among the early smartphones, after all, Apple has iTunes, iPod and other software and hardware technology accumulation and UI design reference. At the same time, with the continuous improvement of iPhone products, more and more iPod users are getting used to listening to audio through iPhone.

There are also many Android cell phone manufacturers who focus on cell phone audio experience, such as Vivo, which has a high pursuit of cell phone sound quality. The Vivo X1, the world's first Hi-Fi smartphone, was released on November 20, 2012, with powerful audio strength at both hardware and software levels: not only the star-level Cirrus Logic's CS4398+CS8422 decoding solution, but also the provision of music content, software-level sound quality repair, hardware decoding, professional audio quality and standard headphones. sound effects and standard headphones in five areas. And after that, Vivo cell phones continue to make efforts on HiFi phones, bringing X3, Xplay, Xplay 3s and other works one after another.

Meizu Pro6 Plus

HiFi cell phone concept is a big hit also let other cell phone manufacturers of the race to follow. For example, in 2016 Meizu launched the Meizu Pro6 Plus, built-in ES9018K2M decoding chip, coupled with attentive tuning, its sound quality performance is not inferior to some professional MP3 products, Xiaomi also launched a HiFi phone equipped with ES9018K2M audio chip Xiaomi Note. this time, HiFi phones are really popular, mobile audio in cell phones The status of the mobile audio in the mobile phone has also been improved as never before.

But HiFi cell phones are popular for a shorter period of time, on the one hand, is affected by the iPhone 7 elimination of the headphone jack, on the other hand, is because the focus of cell phone manufacturers development is shifting from audio to other areas such as imaging, games. In other words, cell phones in people's daily lives can play a more diverse role, it is no longer just an MP3, more can be a professional camera and even a game machine, and therefore the decline of the late HiFi phones is inevitable.

Now, although there may not be manufacturers willing to develop HiFi phones, but does not mean that smart phones can ignore the sound quality performance. On the contrary, due to the arrival of the epidemic, when many companies choose to let employees work at home, people from the constraints of the headset often pay more attention to the audio performance of the phone out; at the same time, the pursuit of immersive gaming experience also makes the importance of cell phone audio performance has been greatly enhanced, the explosion of the concept of e-sports has accelerated the development of related needs; the rise of Vlog short video in addition to the phone front and rear camera The rise of Vlog short video not only has a greater test on the quality of the front and rear camera, but also puts forward higher requirements for cell phones to include audio and external performance.

At present, the difference between the flagship products in terms of performance, image and battery life has been very small, but in the details of the configuration and the support of the subdivision of the use of scenarios are different. As a result, consumer demand also changed from high-performance, good photography, strong battery life of the phone to the overall configuration, performance in the first echelon, such as mobile audio and other details of the same configuration in place of a comprehensive cell phone.

For mobile audio, no headphone hole iQOO 8 series how to respond?

 As a new brand established by Vivo on February 12, 2019, iQOO cell phones in audio performance naturally also inherited Vivo's consistent pursuit of cell phone sound quality. In iQOO 8 series phones, in addition to more powerful hardware configuration, such as audio performance and other details configuration iQOO phones also pay attention to. 

iQOO 8 Pro is equipped with a new upgraded stereo dual speakers, which can bring surround sound effect and low-frequency fuller, wider sound field of listening, so that the user's listening experience to get a significant improvement.

The iQOO 8 Pro's upper speaker for the first time using 1210 closed Box, the equivalent volume of the cavity from the original 0.5cc to 0.7cc, the phone will get a substantial increase in the effect of low frequency when played out. At the same time, the upper speaker and the bottom has a separate cavity of 1611 + BOX ultra-linear speakers with iQOO 8 Pro to obtain a more excellent balance performance, the overall audio effect is significantly improved.

In addition to the iQOO 8 Pro's dual-speaker boost, the iQOO 8 series as a whole also uses a set of full-link sound quality improvement program. The program opens up every link in the cell phone audio transmission chain, including the research and development and optimization of the audio source, transmission path, device side and other links, and then achieve the full link of sound quality improvement. The whole program is divided into the following points.

-Audio: Completing the missing high-frequency details of the network audio source.

-Hi-Fi transmission channel: to make the original audio stream achieve lossless effect and obtain Hi-Res AUDIO and Hi-Res AUDIO WIRELESS dual certification.

-Hi-Fi chip support: let iQOO 8 get more thrust, with a broader sound field, more layers, better detail; -Headphone adaptation: flatten the frequency of the headphones.

-Headphone adaptation: flattening the frequency response curve to ensure the consistency of the sound of different headphones.

-Super Audio: centering the external sound field and supporting scene differentiation for customized sound.

-The iQOO 8 series can analyze the user's hearing condition and improve the phone's sound accordingly.

In general, whether it is external playback or internal playback after inserting the headset, iQOO 8 series have targeted solutions to support. In the true wireless headphones are prevalent today, iQOO is still able to launch a full-link sound quality improvement program for the use of plug-in headphones scenario, which is quite praised. And iQOO cell phone on the mobile audio so much effort, the reason must also be for the future of the full-link audio solutions to prepare.

Xiaogang has something to say

Although the audio performance of a cell phone is often overlooked by consumers, but its importance in some specific use scenarios will come to the fore, iQOO has been insisting on the development of mobile audio technology is the reason for this. I believe that in the future, our cell phones will also include more immersive audio features/effects. Imagine, when we use the phone to watch movies when the speaker can deliver a wider sound field, stronger bass and more shocking sound, the phone's audio, video and other comprehensive experience is bound to go to the next level.
