Set your phone to vibrate (your house)

Basically a 120 volt (220 everywhere else) bluetooth external ringer. If you know what a pile driver is you know what I’m envisioning. The device plugs into an outlet, and clamps onto a structural member of the house. In the basement it could be a joist, or upstairs a doorframe. The device uses a powerful linear actuator that reciprocates the weight the machine itself at a user selectable frequency and amplitude. The machine would weigh about 10 lbs.

I like to set my phone down at home, but like the idea of a silent ring. This would enable a vibration to be transferred through the house. And assign vibration intensity to certain contacts in your phone. You could have the device take the pictures off the wall when your boss calls, make it thump to the rythm of your heart when your significant other is calling or have it produce little 'ticks' when a restricted calls.
