Today, a friend suddenly asked me a question: "mobile phone is so thin, what vibration?
Well, that's an interesting question
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
Some are even made in button form
No matter how small it is, the principle will never change.
Brother, do you understand ~
