How to lower the volume of the vibrator?

Question

Electronics

I decided to have fun with electronics and build my own vibro alarm clock.
The basis of arduino, everything is clear here. The vibroelement itself was taken from kiai to sex toys, because there is no desire to order an official arduino module from somewhere.
I want it here and now.
Collect then collected everything.
Yes, but I don’t live alone and I collected this alarm clock just in order not to wake the neighbors with an ordinary alarm clock.
But only this vibrator does not fulfill its main task, it is still heard in the next room.
What can be done about it?

Answer 1

Buy Xiaomi Mi Band and don't worry. Or use a vibration motor from a mobile phone (30-60r)

Answer 2

about the title, exactly,
but in the case - to put an alarm clock under the pillow
and yes - how much did the vibro cost? it was possible to take a motor with a connecting rod from a Chinese gamepad
