I am not sure what it looks like for a blackberry, but with a sidekick, the vibrator is a simple tiny motor with half "flywheel", so when the motor runs, the flywheel, being half, spins and vibrates. There is no way to "increase or decrease" it unless I guess the device is able to vary the speed of the motor to give a different vibration sense.

Anybody know how BB vibrates? same technique? I saw a number of photos of bb disassembled but I realized I have not noticed anything related to the vibrating component.
