Controlling a DC motor from an Audio Input (need help for deaf brother
(OP)
Hello,
I am trying to control a 1.5V - 6V DC motor from an audio source. I would like the motor to vibrate harder if the noise is louder, softer if it is quieter and not at all if there is no sound. My brother is deaf and he likes to turn the volume up on his computer so he can feel the sound. As you can imagine, my parents get really annoyed at him for making so much noise. So I thought I would build him something to give him the feeling but not make so much noise.
Does anyone know how I can control the 1.5 - 6V DC motor from an audio source? The audio source would most likely be the audio out of a computer's sound card. I know that there is a backpack that you can buy that does this sort of thing, but that isn't what doesn't really fit this situation. I also plan on building it twice so he can have a stereo sensation. PLEASE if you know how to do this, please let me know! I would like to give this to him for x-mas.
Thank you for your help!
Eric

On the switching regulator design, I failed to mention that this is the type with two outputs for push pull design. If you use only one output, you get an on duty cycle from about 5 to 45%.
