Nowadays, smart phone has been very popular, penetrated into all aspects of People's Daily life, Like life, shopping, transportation, entertainment, office and so on are inseparable from it. With the advancement and development of technology, smart phones are more and more beautiful in appearance, more and more perfect in function and better in user experience. Smartphone screens, in particular, are getting more tactile and realistic because each smartphone has a highly sophisticated vibration motor built into it to provide interactive vibration feedback.
In the field of smart phones, vibration motors can be divided into "rotor motors" and "linear motors" in terms of structure. Among them, the principle of the rotor motor is to use electromagnetic induction, using the magnetic field caused by the current to drive the rotor to rotate to produce a full range of extreme vibration experience. The advantage of the rotor motor is that the technology is mature and the cost is low. It is also the standard configuration for most mid-to-high-end and almost all mainstream price mobile phones.
The principle of linear motor is similar to the mechanism of pile driver. It is an engine module that directly converts the electric energy into the mechanical energy of linear motion by relying on the mass of a spring moving in a linear form
At present, linear motors can be subdivided into two types: horizontal linear motors (XY axis) and circular linear motors (Z axis). horizontal linear motor in addition to the vibration can also bring about before and after the four directions of displacement, and the circular linear motor can be regarded as an advanced version of the rotor motor, have felt the experience of compact, which stopped the check.
The cost of a single rotor motor is about $ 1, while the cost of a high-quality horizontal linear motor is as high as $ 8 to $ 10, and the cost of a circular linear motor is in the middle.
If you're a former iPhone user who's obsessed with the way the round Home button feels when pressed and flipped, you'll need a boost from a higher-quality motor.
As we all know, iPhone users have long complained that the Home button is easily damaged. As a result, apple removed the physical button design from the iPhone 7, only retained the style of the Home button at the bottom of the screen, but it is only a virtual button and needs to use vibration feedback to replace the physical touch.
However, from iPhone 7 to iPhone 8, many users have no idea that their phone's keypad is not a physical button, because every time they press the Home button to unlock their phone, you obviously feel that this button has been "pressed down"!
Behind the experience is a $10 "TAPTIC ENGINE" module, that is, the credit of the LRA horizontal linear motor, which can truly simulate the click feel and obtain real-time touch feedback.
In the future, 3D structured light will dominate the smartphone space with face unlock and on-screen fingerprint recognition, which uses a finger to touch a specific area of the screen to identify fingerprint information. The question is again, when most mobile phones adopting under-screen fingerprints, what else can you compare?
The answer is to match the virtual prompt icon with the horizontal linear motor to provide a tactile feedback experience that is comparable to or even beyond the mechanical buttons. At the moment of unlocking, the user feels that the pressed portion of the screen can really be pressed down and then bounced back. Although it is only a short moment, this real 3D Touch experience is a design that high-end users are willing to pay for. Isn't it?
