In recent years, flagship phones have tended to focus on the physical experience rather than the score standard. Take the better linear motor, for example.
Today, the flagship phone with a linear motor has three steps: the one plus 7 Pro, the meizu 16s and the OPPO Reno 10x zoom.
We will do an analysis of the linear motor, see why the flagship of the linear motor can be called king.
The same motor is very different
The first thing to say is the difference between linear motors and ordinary rotor motors.
In fact, linear motors are also divided into z-axis longitudinal linear motors and transverse linear motors, although they are both linear motors, but the effect is very different, we generally speak of linear motor is transverse linear motor, which is the apple OPPO Reno 10 times zoom version of the linear motor.
The z-axis longitudinal linear motor theory experience is not much different from that of ordinary rotor motors.
Lateral linear motors are designed to move you back and forth, right and left, creating a very good vibration sensation, known as omni-directional vibration feedback, which is more direct and three-dimensional than ordinary rotor motors and z-axis longitudinal linear motors.
However, the cost of the transverse linear motor is several times that of the ordinary motor scheme, and it is also larger, occupying the space that should be occupied by the battery, requiring higher requirements for the design and layout of devices and power consumption control. It is because of the cost and design difficulty that transverse linear motor is difficult to popularize.
Software optimization is also important
In addition to cost and design, even with a lateral linear motor, there is a lot of optimization to be done to achieve the experience, and even more so with software than with hardware.
For the calibration of the linear motor (LRA), in the joint application of the system level, are the focus, when can get the response of the linear motor, and the response of how the frequency and length at the same time, these are all very elegant thing, if you want to achieve the iPhone experience, in addition to hardware support, the system optimization of kung fu is also essential.
