x-axis
x-axis linear motors are generally used in mobile phones for ringing vibration and touch vibration. X-axis linear motor is mainly used to simulate the physical keys of the original mobile phone, providing better vibration feedback effect. The working principle of X-axis linear motor is similar to that of pile driver. In fact, a linear motor is a spring mass moving in a straight line, which directly converts electric energy into mechanical energy moving in a straight line.
for rotor motors, the cost of linear motors is not only a little higher. There are two kinds of linear motors on the market now: transverse linear motor (XY axis) and circular linear motor (Z axis). Compared with transverse linear motor, the performance of circular motor may be slightly worse.
Now the transverse linear motor is the best vibration scheme in the market. The cost of transverse linear motor is higher than that of circular linear motor. In addition to vibration, linear motors can also simulate various tactile sensations. For example, Huawei Mate4, which cancels the volume button, can bring feedback similar to the volume button through a linear motor.
The virtual keyboard of the mobile phone imitates the mechanical keyboard, and it will make a "click" sound when typing. When setting the alarm clock, the time axis simulates the feeling of sliding of the sliding pulley; When shooting with zoom, sliding zoom really brings the feeling of turning the lens. Even the gunfight game simulates the reality of shooting, that is, the 4D shock of the game.
