SOUND GENERATOR AND VIDEO GAME MACHINE EMPLOYING IT

摘要

When any one push button switch of a controller (40) is depressed under a state where a sound input mode is selected, a video game machine body (10) generates a frequency data of a musical scale corresponding to the depressed switch and stores it temporarily. When a joy stick (45) of the controller (40) is tilted in a specified direction, the video game machine body (10) modifies the generated frequency data according to the tilt amount of the joy stick (45). Sounds of a variety of musical scales can thereby be inputted using a limited number of push buttons. The frequency data stored in the video game machine body (10) is eventually read out and converted into a voice signal which is then outputted from a speaker built in a CRT display (30). When a music based on the inputted sound matches a preset music, the video game machine body (10) modifies the progress of a game variously. For example, a hero is warped to a position different from a current position or various items are imparted to the hero.
