Recently, because of a video, “Buzz” and “DaDaDa” have become hot words in the technology circle these days.
In the video, the mobile phone has turned on typing vibration, and the experience of various manufacturers can be described clearly:
Meizu 16s response is very crisp and sharp, “Da Da Da”;
Most mobile phones are slow to respond, the vibration is not crisp, and it is very warm to swallow, it is “噗噗 噗”;
A small number of mobile phones have a poor vibration experience, they are not crisp and the whole machine is shaking, and they have won the title of “humming”.
With the release of Xiaomi 10, this year ’s evaluation video half a year ago has received 2 million views, and with the retransmission of some executives, it has created a storm of public opinion.
However, today Xiao Lei talks about the ins and outs of “buzzing” without talking about torture and marketing.
Apple sacrificed the headphone jack in order to “DaDaDa”
To talk about the difference in vibration feeling of mobile phones, let’s start with the iPhone.
In the iPhone 6s era, Apple introduced a new technology: Taptic Engine .
If you remember, the iPhone 6s was the first mobile phone equipped with 3D Touch. Jony Ive, then Apple ’s chief designer, explained that 3D Touch has three layers of operations: tap and tap to browse (Peek) , and press again to see specific information (POP) Apply pressure to enter the menu.
In order to satisfy the “weight press” in Apple’s mind, in addition to a touch layer that can sense pressure, a vibration motor that can provide clear feedback is also important.
The Taptic Engine was born like this.
Except for the iPhone, most mobile phones use a rotor motor and a longitudinal linear motor.
Starting from the rotor motor (flat motor) , you can see from the figure that the rotor of the rotor motor is not in the center.
When the motor is rotating, the rotor that is not in the center will generate a centrifugal force. This centrifugal force causes the motor to move slightly and generate vibration.
So many mobile phones move slowly when they shake, just because the eccentric rotor is moving.
When the iPhone did not support panoramic photography, a manufacturer named Cycloramic used the iPhone 4 ’s rotor motor to make the phone vibrate and rotate to take panoramic pictures automatically. This idea received a $ 500,000 venture capital investment.
Rotor motors are used a lot on domestic machines and early iPhones for no reason: Small and compact .
Except for the Qianyuan machine, we rarely see the rotor motor in the mid-range machine.
The “buzz” we hear today is from a flat rotor motor.
In the later years, with the increasing volume of mobile phones, the “rotational force” of the rotor motor was not enough.
So, the longitudinal linear motor (Z-axis motor) was born.
Note here that “vertical” refers to the thickness of the phone .
Although the longitudinal linear motor is also round-shaped, compared to the rotor motor, it uses the thickness space of the mobile phone, has a smaller size, is more energy-efficient, and has a stronger sense of vibration than the rotor.
Of course, because the volume itself is not large, and the thickness of mobile phones is generally within 1 cm, which also means vibration “”Keystroke” is not high, but it won’t “buzz”.
On the iPhone 6s, we are familiar with the transverse linear motor .
It can be seen from the figure that the “key travel” of the horizontal linear motor is longer , after all, it uses the width of the mobile phone.
It also has a cost higher than a longitudinal linear motor. The longitudinal motor costs about $ 5, and the single linear motor costs between $ 8 and $ 10.
To achieve an excellent vibration experience, the volume of the motor must be large.
In fact, the iPhone 6 already has a horizontal linear motor, but due to its small size, it still fails to meet Apple’s requirements.
Until iPhone 6s, Apple dropped the blood and put on a “huge” vibration motor.
With the iPhone 7, Apple doubled the size of the vibration motor, taking up space in the headphone jack.
The mechanical structure of the Home button has also disappeared, becoming a fixed button, and the original mechanical feedback is also simulated by the motor vibration.
Not only the iPhone, Apple is also deploying the Taptic Engine on MacBook Pro and Apple Watch.
It’s no exaggeration to say that the MacBook Pro’s press feedback is very real, and it will not be considered a fixed glass plate at all.
The Apple Watch’s reminder function is like the watch “knocks” your wrist.
In the iPhone 11 series, although the 3D Touch touch layer was canceled because of the screen module, (Eating chicken artifact, who knows who uses it) .
But the iPhone XS’s Taptic Engine, with a volume of 950 cubic millimeters, can be adapted for almost all apps.
In terms of vibration feedback, the iPhone is still a lot of other manufacturers.
Essence of “linear motor”
In the past two years, as domestic production has gradually advanced, not only is hardware configuration to keep up, how to make a “flagship-like” experience has become an important topic.
The linear motor has also become an important position for publicity.
Although linear motors are used, the horizontal and vertical experiences are very different .
The “linear motor” of most manufacturers is only the second one, and it can’t reach the third one of the iPhone at all.
After the “marketing” wind, Meizu stood out. On the Meizu 15 Plus and 16s Pro, both horizontal linear motors were launched, leaving a lot of other manufacturers behind.
After Meizu, Xiaomi Mi 9 Pro, Xiaomi Mi 10 and Mate 30 Pro also launched horizontal motors.
Although the current disassembly, the size of these motors is still not comparable to Apple.
But compared to the original vertical motor and rotor motor, the experience has no idea where it goes, which is why in the opening video, Meizu ’s vibration feedback is much better than ordinary mobile phones.
Of course, different factoriesOptimizing strategies are also different. For example, the “typing vibration” of major manufacturers is not implemented on the iPhone. It may be that Apple believes that people’s typing speed is too fast and the motor can’t keep up.
Good motors are good, but don’t miss the marketing tactics
The “buzzing” incident can reflect that users’ “experience requirements” for mobile phones are getting higher. Screen quality, speakers have become the conditions for buying mobile phones, and the previous “extreme price / performance ratio” cannot give them these.
But in the final analysis, Mobile phones are the art of balance and compromise , iPhone vibration is good, but it costs extra dollars to give up the headphone hole to exchange for vibration. ?
Obviously, consumers have different voices. Otherwise, no one would spend a lot of money to equip the iPhone 7 with a headphone jack.
For manufacturers, handsWhich feature of the phone to choose is also a multiple choice question: battery, screen, signal, fast charge, camera, battery life, performance, background, each manufacturer has its own priority, but Xiaolei believes that “shock” is not the first.
Of course, Xiao Lei will not take it for granted that the rotor motor is “obviously shrinking” at the same price.
However, both parties in the vortex of public opinion are actually horizontal motors on the flagship machine, but they are clamoring for each other’s non-flagship. The best-performing Meizu, however, did not use “humming” to make a fuss.
A 60-pointer who mocks a 20-pointer as if he scored 90 points, but the person who actually scored 90 points was just shot.
This “buzzing” incident is not a tribute to Meizu’s courage to cut things, nor is it to criticize some manufacturers for saving. From the beginning, it has nothing to do with “technology” and “experience”. It is just that manufacturers are attacking each other. Another proof of digital brand fan circle.
Marketing is like a battlefield, but this should be a battlefield of technology + propaganda according to regulations, not a battlefield where the two sides exchange concepts and scold each other.
Not that you don’t hate competition, but it’s really annoying.
