yes.
the p>iphone13 is a linear motor.
3D Touch is a three-dimensional touch technology, and the screen can sense different touch pressures, so it is called a new generation of multi-touch technology. By adding a layer of Strain Gauges deformation sensing layer at the bottom of the screen, the deformation caused by the user's clicking on the screen can be detected, and then the touch feedback can be realized with the help of the Taptic Engine vibration engine, so that the user can realize two kinds of dynamic interactions of "Peek light pressure" and "Pop heavy pressure".
Apple has a good intention in this regard. On the one hand, it has increased pressure sensing, and different functions can be realized by applying different pressures on the touch screen. On the other hand, it has equipped a horizontal linear motor as touch feedback for rich pressing operations, and it has done a perfect combination of the two. The linear motor is used to simulate the vibration of pressing the key, so that the home key can be cancelled and made into a pressure sensing type to improve waterproof performance and key life.
definition:
linear motor, also known as linear motor, linear motor, linear motor and push rod motor, is a kind of transmission device that directly converts electric energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be seen as a rotating electric machine cut radially and spread into a plane.
The linear motor of mobile phone is actually a spring mass block that moves linearly, which directly converts electric energy into linear mechanical energy without any intermediate conversion device. Due to the spring constant, the linear motor must be driven around the * * * vibration frequency in a narrow band (2Hz), and the vibration performance will be reduced by 5% at 2 Hz.
in addition, when driving in the * * * vibration state, the power supply current can drop sharply by 5%, so driving in the * * * vibration state can greatly save the system power consumption.
