  • Vibration apparatus capable of generating and externally transmitting a sound wave of audible frequency and transmitting a vibration for notification
    Patent number: 6211775
    Abstract: Disclosed is a vibration apparatus capable of generating both a sound wave and a vibration with a simple structure due to the fact that a driving control section selectively supplies a current relying upon a kind of frequency of the current inputted from the outside. If a high frequency current is inputted into the driving control section, because a vibrating body vibrates up and down by interaction between a magnet and a pair of vibrating coils which are disposed in a side-by-side relationship such that they are opposite to the magnet, a sound wave is generated whereby it is possible to notify of reception of an incoming call by the sound wave.
