Android: set vibration power

Question

I am currently working on a project where I would like to use a vibration motor located inside an Android phone.

I realized that I set the correct resolution in the manifest and got a vibrator instance:

Vibrator v = (Vibrator) game.getSystemService(Context.VIBRATOR_SERVICE);

will give me access to it. As far as I can see, the only ways to make it vibrate are:

public abstract void vibrate (long milliseconds)

and

public abstract void vibrate (long [] pattern, int repeat)

But I would like to control the power of vibration:

How can I control the power of vibration?

Update:

Should speed be controlled with AC voltage (or PWMing DC)?
