The phone speaker just listens, don’t forget to have these perverted designs.

Let’s talk about a story about “swiping with the child and moving over the boat”: the intensity of the thermal power is greater, the sound is warmer; the sound of the water and electricity is cold, but the resolution is Very high. In hydropower, the electrical tone of Gezhouba is the best; in thermal power, the electrical sound quality of Beilun Power Plant is the best, because the proportion of burnt anthracite is the highest...·····

The above paragraph leads to the topic of this issue - the mobile phone. However, in a few years, independent DACs and op amp chips were integrated into the smartphone, and Hi-Fi, which was originally a small sentiment, lowered the threshold. Nowadays, mobile phones can achieve high-quality audio output, and the external release is no longer just a sound. Let's take a look at the vendors that go straight to the top nine, and what are the metamorphosis designs in the mobile phone.

Scene 1: There must be stereo

When it comes to mobile phones, I have to mention HTC BoomSound first. In 2013, HTC officially launched a dual front stereo speaker on the M7, which is officially called “Yuedong Audio”. The most obvious sign of BoomSound is the two long speakers on the front and back of the M7, and HTC has also carefully adjusted it on the software level.

BoomSound cleverly designed two speakers on the front of the phone with the sound directly towards the user. The built-in speaker amplifier is a booster-like component that doubles the sound of the speaker without sacrificing sound, and the sound quality is clear and pleasing.

Of course, BoomSound is not perfect. The obvious drawback is that it takes up too much internal space, resulting in a low percentage of mobile phone screens. HTC 10 still retains this feature, but the main speaker at the bottom of the phone is mainly used to play the low frequency, and the earpiece is responsible for the high frequency, which is wit like me (HTC).

The second act: not as good as the power

At MWC 2016, Alcatel of TCL released the fourth generation of IDOL product lines, namely the IDOL 4 of the 5.2-inch screen and the IDOL 4S of the 5.5-inch screen. The biggest highlight in terms of audio is that they have two built-in 3.6W speakers.

To match this ultra-powered speaker, the IDOL 4S is also equipped with the NXP Smart Audio audio chip TFA9890, which brings higher volume, richer bass and better sound quality to the phone. It also integrates the intelligent CoolFlux DSP, which is designed to effectively protect the speakers while maintaining peak output.

Do you think this is over? wrong! In addition to the sublimation of the hardware, the software upgrade is also a must. IDOL4S also has built-in Waves MaxxAudio. Anyone who has used the computer knows that this is a sound enhancement software on the computer, and now it has finally arrived on the phone. Can effectively enhance the sound quality of the sound and enhance the three-dimensional sense!

Act III: New Realm of Stacking

In September last year, Meizu released its 2015 flagship machine, PRO 5. In addition to powerful hardware specifications, the most eye-catching feature of the PRO 5 is its outstanding audio performance. The PRO 5 is a stacker in audio handsets. In addition to the ES9018K2M and OPA1612 on the MX4 Pro, the Solo amp circuit and four pairs of NXP high-current transistors are added.

Regarding the external release effect of PRO 5, Meizu uses the term “strong and powerful” to describe it. Based on the second-generation NXP Smart PA, Meizu re-modeled the PRO 5 speakers and updated the algorithm, greatly enhancing the low-frequency listening. At the same time, the noise floor does not increase with the volume, but the sound is pure and accurate, without burrs and broken sounds.

The fourth act: add a plug-in

what? Are you actually dying to build all kinds of audio hardware? In this case, I will open the plug-ins without mercy! The modular design of the LG G5 is eye-catching and users can freely change the chin. Currently, it includes a built-in battery camera handle and a Hi-Fi module built in cooperation with B&O.

The LG Hi-Fi Wizard is a combination of LG and B&O. It has a built-in independent B&O PLAY 32-bit Hi-Fi DAC decoder and Amp amplifier, which can restore pure music in a clearer and less distorted way. Audio enthusiasts need to purchase separate amps separately.

Of course, this Hi-Fi module can not only be used with the LG G5, but also can be used as a stand-alone DAC plus Amp function. Users can even transfer the audio digital signals of the iPhone and computer to this module, let them decode, and then zoom in. The analog audio signal is output to a headphone or stereo.

The fifth act: flying together with the plug

The LG G5's Friends module has opened up the modularity of smartphones. Some time ago, Motorola Moto Z also joined the modular camp: Moto Mods was launched. As the latest modular smartphone, the most attractive place is of course to cooperate with JBL. Launched the Magic Sound - JBL speaker module.

Like all Mods accessories, the Magic-JBL speaker module has a magnetic interface on the top and bottom that can be connected to the Moto Z. The speaker module has an extra 1000mAh battery built in. Although it looks like the battery capacity is not too large, Motorola says it is enough to stick to 10 hours of play time.

In terms of sound effects, there is no magic sound - JBL speaker module, the difference between the two is very significant. Although the built-in speaker of Moto Z is not bad, with the magic sound-JBL speaker module, the whole sound sounds more solid.

to sum up

For enthusiasts who are really pursuing Hi-Fi sound quality, these external design is not enough. However, from another perspective, mobile phone manufacturers can put down the performance package and add a variety of independent audio chips, which greatly enhances the user experience. For these manufacturers, I just want to shout: "Too servant is old, and I am traveling with me."
