Not long ago, we at Sanyi Life came to a conclusion through the analysis of the Leitz Phone 3, which has an orthodox Leica lineage. That is, under the current technical conditions, even the top image flagship, there is completely internal space to put down the 3.5mm headphone jack, and the reason why it will become more and more rare, in fact, is just "I can't do it, I really don't want to".
In fact, when we wrote this content, we really didn't expect to be able to "touch" any mainstream manufacturer. After all, we all know that the wireless earphone market is in the ascendant, and the era of HiFi mobile phones is long gone.
Because of this, when we recently saw a "mobile Internet audio device" exposed by the domestic audio manufacturer Shui Yueyu, we were undoubtedly excited.
Shui Yueyu makes HiFi phones, although they may not necessarily admit it
Yes, you guessed it right, the so-called "mobile Internet audio device" is actually a name for HiFi mobile phones. Considering that Shui Yueyu had never set foot in mobile phone products before, they promoted their HiFi Walkman, which can make calls and take photos, and deliberately avoided consumers from comparing it with mainstream smartphone products, in fact, we think there is nothing wrong with it.
But if you carefully study the product pictures and related parameters that have been revealed so far, you will find that this product called "MIAD01" is far from that simple.
According to relevant revelations, Shui Yueyu's HiFi mobile phone will provide two headphone jacks, one of which is a traditional 3.5mm headphone jack, and the other is a 4.4mm headphone jack that has never appeared on a product like a HiFi mobile phone before. And its 4.4mm headphone jack will definitely adopt a fully balanced circuit design, which will theoretically have more output power and a much higher signal-to-noise ratio.
Seeing this, I don't know if everyone is already excited. Some enthusiasts may think that Shui Yueyu didn't build a "national brick", and then add the network function of a mobile phone to it.
However, this may not be the case, and this is also the focus that we want to dig into the most in Sanyi Life.
Shui Yueyu has no experience in "making machines", and this new product may not be an original design
According to some current leaked information, the size of the MIAD01 in the entire lower part of the fuselage is actually no different from the current mainstream smartphones. It will not be as heavy as most domestic stacking HiFi players (also known as "national bricks"). But in the position of the rear camera, the MIAD01 will have a more obvious convex structure, which is somewhat similar to the appearance characteristics of Sony's previous high-end players.
Experience has shown us that such a bump will make it easier to increase the width of the bezel on one side of the device, allowing it to fit the huge 4.4mm headphone jack. But in addition, from the seemingly unnecessary rear camera configuration (single main camera + several secondary cameras) of Shui Yueyu MIAD01, we smelled a more "dangerous" signal.
Yes, in fact, there is more than one of us Sanyi Life who speculates that Shui Yueyu's "HiFi mobile phone" may not be completely original, and it is likely to be based on OEM products. And the raised structure of the upper part of the back is not just to put down the headphone jack, but more likely because it is an additional audio circuit board inside.

To put it more thoroughly, that is to say, in terms of the internal structure of the water moon rainMIAD01, there is a high probability that it will not be like OnkyoCMX1、Haibei R8 and other "hardcore mobile players",A large area in the fuselage is audio circuits。 At the same time, of course, it can't achieve the same high level of integration as the previous vivo XPlay6, so that the HiFi mobile phone is no different from the mainstream models in terms of appearance.
Shui Yueyu has never made a "national brick", but they do have the experience of "HiFi Little Tail".
For Shui Yueyu, the most likely way to realize the function of their "HiFi mobile phone" at this stage is to "graft" a circuit similar to the "small tail" of a USB decoder to the upper back area of an ordinary mobile phone. Of course, it may not be a completely "plug-in" circuit board, but there is a high probability that there will not be a highly integrated audio architecture.
"Hanging in" a small tail, such an architecture may really be the future
Honestly, if you're a HiFi player who pays a lot of attention to "stacking", you might think it's too simple. But in our opinion, it is this seemingly "simple" design that reflects two very noteworthy facts.
Shui Yueyu's previous co-branded DAP products, the essence of which is Shanling M3X skinning
As long as you have used integrated HiFi mobile phones and used today's external "little tail" decoder, you will know that these "little tails" will have some significant advantages because they are different from the built-in HiFi circuit in terms of audio processing logic.
For example, in some professional playback software, you can turn on the exclusive mode when you recognize the external audio decoder to get better sound quality. At this time, other system sounds will not be broadcast at all, which is precisely what the built-in HiFi solution cannot achieve.
The "little tail" can enjoy a USB exclusive mode that is not available with the built-in HiFi circuit, while also having a higher uplink limit
Another example is that the external decoder is only responsible for the output of the headphones, not the speakers, so it will theoretically be more power-efficient. When the user is not plugged in, the external HiFi circuit can even completely cut off the power and do not work.
In addition, looking at today's HiFi player market, you will find that in fact, the objective indicators of devices are not necessarily directly related to their "size" in many cases. Many seemingly small "little tails", their signal-to-noise ratio and frequency response can now be better than "brick" products, and even the price can be higher, and they are recognized by many consumers.
Haibei R8 is the first domestic HiFi DAP that supports cellular networks, but it cannot be regarded as a mobile phone in terms of architecture and function
So this also seems to show in turn that instead of adding communication functions on the basis of "brick machine", like Shui Yueyu now, it is suspected that the design of the "small tail" directly built into the mobile phone will be quite good in terms of user convenience and actual sound quality.
Of course, if Shui Yueyu's HiFi phone really "becomes", will it spur another revival of this market and inspire more manufacturers to make better products? Honestly, we are very much looking forward to seeing such a future. But for now, at least, it's just an expectation.
