In a predetermined sound generation mode, a drive signal having a frequency characteristic corresponding to an operated key is supplied to an excitation unit provided on a soundboard. In response to a mechanical vibration generated by the excitation unit, the soundboard is vibrated so as to generate an acoustic vibration sound corresponding to the operated key. The excitation unit is supported by a supporting unit such that less or no load of the excitation unit except a vibration member vibrated in response to the drive signal is applied to the soundboard. Thus, only a load of the vibration member which is a very light portion of the excitation unit is applied to the soundboard, thereby vibration characteristics of the soundboard being hardly affected. When a sound damping mode is selected, a stopper is permitted to prevent a hammer from striking a sounding body.

When any of push-button switches on a controller 40 is pressed in a sound input mode, a video game machine body 10 generates and temporarily stores frequency data of a tone corresponding to the pressed switch. At this time, when a joystick 45 on the controller 40 is tilted to a predetermined direction, the video game machine body 10 changes the generated frequency data according to the amount of tilt of the joystick 45. It is therefore possible to input various sounds in tone using a limited number of switches. The frequency data stored in the video game machine body 10 is read later to be converted into audio signals, and outputted from a speaker incorporated in a CRT display 30.
