Abstract
The present invention has an object to provide a method for generating vibration and a vibration generating apparatus for allowing a single unit to provide a call signal by way of sound and body-sensible vibration. According to the method for generating vibration of the invention, first and second vibration systems having different resonance frequencies from each other are magnetically coupled to each other and a state of energy externally supplied to the systems is selected thereby causing the first vibration system to vibrate relative to the second vibration system for generating a body-sensible vibration, for example. By changing the state of the energy, the second vibration system is caused to vibrate relative to the first vibration system for generating sound.
