Mobile phone is so thin, what vibration?Overview of vibration motor of mobile phone

Today, a friend suddenly asked me a question: "mobile phone is so thin, what vibration?

Well, that's an interesting question

Mobile vibrator

Mobile vibrator consists of motor and CAM

The CAM (eccentric device) is used to rotate in the mobile phone to generate vibration.

Remove the engine brother will find that the CAM is somewhat similar to the engine balance.They all vibrate, except the engine cancels out the vibration, and the phone vibrates

As the phone gets thinner, the vibration motor gets smaller

SMT Vibration Motor

Some are even made in button form

Coin Vibration Motor

No matter how small it is, the principle will never change.

Brother, do you understand ~
