We all know that mobile phones have become a part of our lives.
But how many people know the principle of “vibration” in mobile phones?
The vibration working principle of early cell phone is related to the eccentric wheel.
The centrifugal force changes continuously during rotation to produce a vibration effect.
But this way takes up a lot of space on the handset.
Until the iPhone4, Apple’s vibrator changed a look.

The noise of linear vibration motor Taptic Engine is very small.
The Apple has patent for it and the patent number in China is: 2005100657635
Linear motor is different from eccentric motor.
Linear motor alternate current through high frequency in two coils to generate a positive and negative alternating magnetic field.
Through the repeated suction and repulsive force to produce the “vibration” we feel.
