What is the motor of a mobile phone used for? Is it as important as the CPU screen or something?

The motor of a mobile phone is currently an indispensable vibration component. In terms of function alone, it cannot rise to a level comparable to that of the CPU and the screen. However, in order to achieve a more perfect and realistic vibration, mobile phone manufacturers currently The vibration effect and the motor used are getting better and better. 1 The role of mobile phone motors

We all know that mobile phones have a vibration effect. In places such as classes, meetings, and public places where you do not want mobile phone ringtones to ring, mobile phones will be set to vibrate mode to detect incoming calls and text messages. When the time comes, the phone will vibrate to remind the user without disturbing other people. This is what mobile phone motors are for. In addition, there is also a very important function, the simulation effect in the game. For example, gun games, car racing games, etc. The vibration effect of the gun's recoil and the effect of a car crash can all be simulated through the motor. Many game manufacturers have put a lot of effort into vibration details. This is the vibration effect of the motor, which is currently one of the essential components of mobile phones.

2 Rotor Motor - Companion of Functional Machines

Mobile phone motors are different from industrial motors. Motors in industry are important actuators that achieve displacement, angle, torque and other functions through the rotation of the rotor. In the era of feature phones, we have all had this experience. When the phone is in vibration mode, when a call comes in, the phone will vibrate and move, and may fall under the table. This is because the vibration motor of the functional machine is mainly a rotor motor. The rotor drives the eccentric block, and the rotation of the eccentric block generates centrifugal force. This is like the clothes not lying flat when a semi-automatic washing machine spins. The washing machine turns on the running mode without water. The vibration effect of the rotor motor is very obvious, but the control effect is relatively poor, that is, it does not start and stop in time.

3 Z-axis linear motor-testing smart machine

There is a difference between linear motors and rotor motors. Linear motors can be divided into longitudinal linear motors (Z-axis) and horizontal axis Sexual motor (X-axis). The Z-axis linear motor should be the first to be used in iPhone 4. Its working principle is that after the motor is powered on, the internal magnets have been making linear motion to achieve the vibration effect. Because the thickness of the mobile phone is limited, the vibration stroke of the Z-axis linear motor is limited, resulting in a weak vibration effect. 4 X-axis linear motor - the king of smartphones

The reason why I mention the king is because some mobile phone manufacturers have exaggerated the important position of linear motors in smartphones and the perfect effects they can achieve. Those who are interested Friends can go find out. Here we only popularize the principles.

Opposite to the vertical axis, the X-axis moves horizontally. It seems that Meizu has used a horizontal linear motor for the first time in China. Nowadays, horizontal linear motors are promoted a lot by friends, and Meizu is probably very depressed. As the name implies, the transverse linear motor achieves the vibration effect through the horizontal linear movement of the mass block. This kind of motor has better effect and higher cost than the longitudinal linear motor. Nowadays, many mobile phone manufacturers use horizontal linear motors to achieve the pressing vibration effect of touch buttons. 5 The status of motors in mobile phones

In summary, mobile phone motors can achieve vibration effects. Judging from the current development trend of mobile phones, motors are indispensable, but they cannot rise up to match the CPU and The screen is equally important. Without the motor, the phone loses its vibration effect, but without the CPU and screen, the phone loses its functions.

The motor in the mobile phone vibrates. A good motor paired with a good tactile engine can provide a very good touch feedback effect. For example, Apple has canceled physical buttons since the iPhone 7 series. , but the vibration feedback of the motor can simulate the effect of physical buttons, which is beyond the reach of most domestic mobile phone manufacturers.

Analysis of the importance of mobile phone vibration motors

Motors in mobile phones are mainly divided into two categories: rotor motors and linear motors. The details are as follows:

There is no unified understanding of the importance of motors in mobile phones. Standard, some people attach great importance to the exquisiteness of tactile feedback, so it is important, but most people have no pursuit of mobile phone vibration, and it is in a dispensable state. Naturally, it does not matter what motor it is paired with, so The importance varies from person to person. The built-in motor of the mobile phone provides a vibration effect

Generally, we use ringtones as reminders for incoming calls or messages. In an environment where the sound is not suitable, if it is set to mute, it is easy to miss important calls or messages. At this time, the vibration prompt is most effective. When playing games and clicking on the phone, there will also be a vibration effect. This vibration effect requires the use of motors.

Doesn’t the motor rotate? Why can it vibrate?

Horses are usually used for rotation, but humans are very smart. We install an eccentric block on the shaft of the motor. When the motor rotates at high speed, it will generate centrifugal force, thus obtaining the exciting force. This is the most common vibration motor. Old mobile phones and most mid- to low-end mobile phones currently on the market use this vibration motor. Although this kind of vibration motor is low in cost, its shortcomings are obvious. When vibrating, it starts slowly, stops slowly, and the vibration has no direction. It cannot meet the vibration sensory needs of Ma Shao players.

Later, smart people invented linear motors, which rely on electrical energy to push a mass block to move back and forth in a transverse linear motion. The kinetic energy of linear motion has different motion directions. Linear motors are also divided into XY-axis linear motors and Z-axis linear motors. Among them, the XY-axis linear motor has the best effect and can simulate various complex and realistic vibration effects. This XY-axis linear motor is rectangular and takes up a lot of space inside the phone. Currently, it is only used by Apple phones and some end phones that pay more attention to user experience.

The Z-axis linear motor has only one direction. The cost is lower than the XY-axis linear motor, and the effect will be worse, but it is still better than the ordinary vibration motor. The Z-axis linear motor is circular, which takes up less space inside the mobile phone and has a better vibration effect. Many mobile phones use Z-axis linear motors. Is the mobile phone motor important? Can I cancel?

From the above analysis, we already know that mobile phone motors are used to provide vibration effects. In turn, let’s ask, will consumers buy mobile phones that only have ringtone prompts, or are set to mute, but without vibration prompts? When playing games, will a mobile phone without the sensory impact of vibration still be favored by players?

To be honest, there are still many iPhone users on the Internet who still miss the perfect feeling that the iPhone 7 brings to their hands and cerebral cortex when they vibrate. The mobile phone motor is the mobile phone vibrator.

(Motor, this thing is really hard to explain. It is too professional, and professional things are generally very boring. I’m afraid you won’t have the patience to read on.) Motor - the English transliteration of motor, meaning electric motor Or engine.

An engine is a power device that converts chemical or physical energy into mechanical energy. (This is too far away from the mobile phone motor, so I won’t go into details here.) 1. The working principle of the eccentric shaft rotor motor is that current drives the eccentric shaft to rotate. When rotating, an eccentric force or exciting force is generated, which drives the mobile phone to rotate periodically. vibration.

2. Linear vibration motor

An excellent motor can do many things, such as simulating the touch of a real button. After Apple 7, in order to improve the waterproof performance of mobile phones, the physical Home button was canceled. However, with the help of the motor, some users found that the Home button could not be pressed after a month of use. When typing, it feels like a physical keyboard.

Regarding the popular science of mobile phone vibration motors, this is it. There are many related topics that are not suitable for examples. Otherwise pollen and mud powder will spray me.

Thank you for reading. The function of mobile phone motors

Generally, the function of mobile phone motors is the vibration of the mobile phone and the tactile feedback of the screen. Is it as important as the CPU screen?

Personally, I don’t think the CPU is as important as the screen.

A good motor can indeed improve the user experience, but the extent of improvement is still far behind that of the CPU and screen. And many friends just turn off the vibration, so it can be said that the motor does not work in these friends’ mobile phones.

Summary

Motors are very popular on the Internet recently, mainly about rotor motors and linear motors. I think that if the price is right, then a good motor is a must. , but if the pricing is limited, then the priority can be slightly backward.

Why are so many people suddenly interested in mobile phone vibration motors? It turns out that Xiaomi Lu Weibing used Honor surgery again, and the inlet is the "buzzing" flat motor. Honor has also been criticized for this. A mobile phone that costs 3,000 yuan also uses a rotor motor. There is really nothing to quibble about. Even Huawei's own Mate30pro also uses a linear motor.

Today, let’s talk about vibration motors. What is the vibration motor of a mobile phone used for? To put it simply, the vibration motor is used to provide vibration for the mobile phone. Anyone who has used a mobile phone will definitely be familiar with it. Through vibration, we can receive reminders such as incoming calls, messages, alarm clocks, etc., and vibration feedback can also give us a better experience when typing and interacting with the system.

In short, don’t underestimate a small vibration motor, it does have a big effect. However, in life, sometimes mobile phone vibration is annoying, and many people choose to turn it off. For such a “dispensable” function, why does Lu Weibing repeatedly criticize Honor’s rotor motor? In fact, there is a saying: You can use it, but you can’t live without it, and you can’t guarantee that you won’t use it in the future.

As a mobile phone manufacturer, it is natural to consider everything comprehensively. After all, some people need a vibration motor, and a good vibration motor is really comfortable. The vibration feedback of the iPhone is the most comfortable, and many people even like the vibration motor because of it, and Meizu is the best in vibration in China.

Vibration motors are mainly divided into rotor motors and linear motors. The former is cheap, has a slow response speed, and has an unfriendly "buzzing" experience when vibrating, while linear motors are just the opposite. This year's mainstream flagships will come standard with linear motors, which are divided into X-axis (horizontal), Y-axis (front and rear) and Z-axis (vertical). Among them, the X-axis linear motor is more popular now, and the vibration feedback is also very comfortable. The specific principle will not be discussed here.

Is the vibration motor more important than the processor and screen?

Of course not, vibration motors are really useless to many people. However, small vibration motors can also affect user experience. For example, the iPhone pays great attention to the vibration of the phone. As the saying goes, details determine success or failure. The more refined and high-end a mobile phone is, the more basic the experience should be. A small motor can indeed reflect a lot of things.

Except for Xiaomi’s mobile phone motors, the motors of all other mobile phone brands are used for vibration. Xiaomi's mobile phone motor drives a car like Tesla, with strong horsepower. A mobile phone motor can drive a car. These people are rushing to buy Xiaomi mobile phones just to disassemble the motor inside and install it in the car, which saves electricity, has high horsepower, and is cheap. Therefore, Xiaomi is the most powerful technology company, surpassing other mobile phone companies not by a few streets, but by several worlds. Okay, now I invite Lu to continue the circle.

The quality of a mobile phone’s motor has a direct impact on the user experience (except for the steel bars that vibrate when the phone is first received). From the lifelike home button of Apple 7, you can understand the potential of the vibration motor.

First of all, Apple is currently the most powerful motor manufacturer in the industry. The size of the motor directly determines the quality of the vibration. Apple's largest motor is on the iPhone 8 Plus, and the models after the X will be slightly smaller. After all, without the home button, the demand for realism is not as great, but it is still The largest motor in a mobile phone. The linear motor used in iPhone 7 can simulate the real pressing feeling.

But the presence of the motor is not as important as the CPU screen. A powerful SOC can allow you to play games smoothly and even open more games, and the life of the phone will be longer, while the screen is used every day They all need to be watched, and the better the screen experience, the better. The best Apple home button currently uses a motor. In addition to this, it also vibrates when ringing and typing, and the experience is also straight up.

Finally, here is a disassembly picture of Apple’s motor, so you can feel the stacking of Apple’s materials for yourself.

The motor is very important to Xiaomi than other components [tears]

Hello! Happy to answer your questions! The front end of the shaft of the mobile phone motor is a semicircular eccentric. When it rotates, due to the imbalance of the eccentricity, it will vibrate to serve as a reminder. If there is no motor, the mobile phone will not vibrate when there are calls, text messages, or reminders. There will only be sound, which is not so sensitive. So you will miss a lot of messages and some calls, but the phone can still be used without a motor or the motor is broken, but the phone cannot be used without a CPU or a screen, so it is not as important as the CPU or screen, but it is still necessary, all Mobile phones all have motors. It’s just that if the motor breaks down, the phone can still be used, but if the CPU or screen is broken, the phone must be repaired before it can be used! The above is my personal understanding, I hope it can help you!
