A non-limiting example game apparatus includes a main body apparatus that functions as a vibration control apparatus and a first controller and a second controller attachable to or detachable from the main body apparatus. For example, the game apparatus can be used in one of a first mode that two controllers are attached to the main body apparatus, a second mode that the two controllers are individually used in a separated state from the main body apparatus, a third mode that the two controllers are used in a state where the two controllers are detached from the main body apparatus and connected integrally to each other, and a fourth mode that a third controller that is different from the two controllers is used. For example, the same type of vibration motor is used for each controller, and a CPU incorporated in the main body apparatus controls a vibration waveform according to the usage mode of the game apparatus.
