Abstract: There are provided a vibration generation device and an electronic apparatus adapted to generate a variety of vibrations corresponding to a variety of situations without making the power consumption excessively high. The vibration generation device and the electronic apparatus according to the present embodiment is provided with two vibration motors having respective eccentric weights different in weight from each other, and drives a first vibration motor having a heavier one of the eccentric weights in the case of announcing a first event, for which notice with a strong vibration is necessary or effective. In contrast, in the case of announcing the second event, for which a quick response or a response performance is required, a second vibration motor having a lighter one of the eccentric weights is driven. The first events include incoming, coming of alarm time, a dynamic or important action, motion, and so on in a game. The second events include confirmation of input operation using a touch or a press on a screen of the electronic apparatus, a minute action, motion, and so on occurring in the game. Further, the correspondence between the vibration motors and the events is made selectable.
