What is the experience of a phone with a lateral linear motor?

For mobile phone users, mobile phone vibration is the most easily ignored function, but in daily life, mobile phone vibration has an important application.The movement of objects back and forth is called "vibration." the most common type of cellphone vibration is the vibration that occurs when the phone is on mute with a text message or call.

In the past, mobile phone vibration was a practical function. In silent mode, the phone would start to vibrate regularly following a text message or call, thus reminding the user not to miss the message or call.

Now, vibration is more of an experience.

For example, when you type a text message, each time you press a virtual button, the phone vibrates and passes it to your fingertips, just as if you were pressing a real keyboard.When playing shoot-out games, the recoil generated when shooting makes the phone vibrate, and the fingertips will feel the vibration of the phone, just like being in a real battlefield.

Vibration motors on mobile phones need to rely on magnetic force to work. According to different vibration principles, vibration motors on mobile phones are currently divided into rotor motors and linear motors.

Cell phone motor?

The rotor of motor

The rotor motor relies on electromagnetic induction to drive the rotor to rotate and produce vibration.The rotor motor has the advantages of simple manufacturing process and low cost, but it has the disadvantages of slow start and directionless vibration.

Nowadays, mobile phones pay more and more attention to the sense of holding, the body is thinner and thinner, and the disadvantages of large rotor motor are more and more obvious. The rotor motor is obviously not suitable for the development trend of mobile phone industry and the pursuit of users.

Linear motor

Linear motors convert electrical energy directly into mechanical energy and drive the mass blocks of springs to move in a linear manner, thus generating vibrations.

Linear motor can be divided into transverse linear motor and longitudinal linear motor.

The longitudinal linear motor can only vibrate along the z-axis. The vibration stroke of the motor is short, the vibration force is weak, and the vibration duration is short.Although longitudinal linear motor has certain performance improvement compared with rotor motor, it is still not the best choice for mobile phone motor.

In order to overcome the above shortcomings of longitudinal linear motor, transverse linear motor should be put into operation.

The lateral linear motor can vibrate along the X and Y axes. The motor has a long vibration stroke, fast starting speed and controllable vibration direction. It is more compact in structure and more conducive to reducing the thickness of the phone body.

Currently, the flagship phone is more of a lateral linear motor, which is used by the OnePlus7 Pro Haptic vibration motor.
