vibration with sound

Hello.

I do not know if this question is in the right category, otherwise just say so. Is it possible to get a sensor there is reacting on sound? That means when a specific sound is registered, a censor is vibrating? An example could be everytime the doorbell was ringing, the vibration sensor vibrated.

Best Regards

You can find smaller ones as well.

Microphones are designed to react to sound.
