How A Mobile Phone Vibration Motor Looks Like And Works Opened Up.
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.
It has a name called Taptic engine.
(iPhone 6s vibrator Taptic Engine under X-ray)
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.
Apple mobile phone uses linear motor for the first time on iPhone 4.
But the iPhone 4s to the iPhone5s use an eccentric motor and uses linear motor again in iPhone 6.
Established in 2007, Leader Microelectronics (Huizhou) Co., Ltd. is an international enterprise integrating R & D, production and sales.
We mainly produce flat motor, linear motor, brushless motor, coreless motor, SMD motor, Air-modeling motor, deceleration motor and so on,
as well as micro motor in multi-field application.
