Hello, im new here,

i have been trying to find out about this everywhere but had no luck my question is this:

How does a motor spin/vibrate with audio? e.g. like the PS2 controller, it vibrates with the sound. how do i make this? what components will i need?

any help at all will be appreciated

thanks in advance

Bump- please someone help...

A small motor with an offset balance or are you asking how sound is converted into voltage?

[Manny-]

Yes im asking how sound is converted into voltage, i want the vibrating motor to vibrate with sound creating vibration as the sound gets higher and lower just like phones when it rings the little motor vibrates with the sound (i hope this makes sense)

Bump once again... come on please someone reply, this is afterall a electronics circuits website someone should know how this is done please help

Like Mike said, you can use an offset weight on the end of the motor shaft to make it vibrate.

But the motor is a rotary device that has inertia when it is running so there is no way you can make it change its speed of vibration to match the audio frequencies of speech or music.

thanks for the reply, i appreciate it.

I was thinking there may be a way because the PS2 controller does the same thing when you hear a loud sound like a gun shot the controller vibrates with it... i just thought there may be a way to do that

but now i know there isn't, thanks again

use offset weight on the end of the motor shaft to make it vibrate but i think it is not possible to generate sound through this because motor cant produce the high vibration in the sense of converting vibrating power to sound.

I know what you mean about the game controllers. They're like the sound-to-light systems only you want sound to vibration. Sure it's possible but I don't know how (yet). However...

Doesn't a microphone convert sound to an electrical signal? And don't transistors amplify signals into useable voltage?

In this case you should pass voltage of the voice or music in the motor which is a rotary device that has inertia when it is running.
