Wiring A Phone to A Bigger Motor

[NickJa]

Hello,

I'm an artist studying in London, UK. I'm trying to make a room vibrate when a phone number is called instead of the phone itself. So far I have experimented with binding electric sanders to the bottom of floor supports just to create the sensation but I am a bit stuck and would like to work with someone whose got the knowhow.

How can I connect the wire from the phones small motor to activate a bigger one? I assume the phone will have to activate some kind of switch rather than be connected but there might be a better way.

I'm going to try and imitate the phones vibrator by attaching a counterweight to a larger motor that I am still to find, or possibly a series of small motors. One factor I think I would like to get control of is the speed that the motor rotates at, in order to mimic the frequency of vibration when you leave a phone on a table.

If I had a motor that plugged into the mains, I would need to somehow activate it with the phone. And If I had a series of small motors, would it be simpler to power them by battery in addition to the phone connecting the circuit?

Any information would be fantastic, cheers :grin:

if you want a wireless solution you can use a [blue tooth module - micro controller - triac/relay - virator motor ] unit.
second option is using optocoupler, with the help of optocoupler you can easily and safely interface a phone with big motor.

Also a DTMF can be used a receiver can trigger the motor

Use optocupler to detect ringing on telephone lines.

NickJa, the conversion of the telephone ringing signal to an electronic/electrical signal is straight forward. Your real problem is with "making the room vibrate". Real rooms are designed to have stiff floors and walls, so an excessive amount of power would be needed to vibrate them. You say that you mounted a sander on a floor support, do you mean floor joist? To make a structure vibrate easily you need flexibility and low mass (loudspeaker cone !!). For vibrating seats, they are typically driven by hydraulic cylinders and valves switching the pressure on and off.
