Abstract
An impactive vibration generating apparatus includes a rotary unit having a shaft and a coil arranged around the shaft; a fixing unit surrounding the rotary unit and having a magnet therein; a commutator arranged along the circumference of the shaft connected to the coil; a pair of brushes to slidably contacting the commutator; a protrusion attached to one part of the rotary unit; and a stopper contacting the protrusion when the rotary unit rotates so as to interrupt the rotation of the rotary unit. According to the impactive vibration generating apparatus, a sharp and strong single impactive vibration or only a few impactive vibrations can be generated. Further, a strong vibration can be caused by continuous impactive vibrations, and the frequency or cycle of the generation of the impactive vibrations can be adjusted.
