1. How does current smartphone vibrate.
2. On internet I had read that it is motor.
3. But i had opened a smartphone completely, except some circuit on it are enclosed in Al case.

I didn't saw any motor anywhere. Any Al case is very thin to house a motor, I think?

Every hand-held cell phone I have taken apart had a vibrator motor inside it. It might not look like a motor and can be encased in plastic as the two motors at the upper-right of the photo below are.

The iphone 4 that I scrapped last night had a motor only 1 cm long including the weight and 5 mm x 3 mm, encased in plastic except for the spinning weight.
