PROBLEM TO BE SOLVED: To provide a game acoustic system, appropriately providing low-pitched tones in the front of a game machine frame. SOLUTION: A front panel 52 and a rear panel 53 that are supported by a frame 54 so as to face each other and to be longitudinally apart from each other constitute a closed space together with the frame 54. A speaker-placed part 63 and bass-output outlets 55 are provided on the frame 54. The part 63 located outside from the rear panel 53 is formed into a longitudinally through cylinder. The outlets 55 open in the front of the frame 54 and in positions different from that of the part 63. A low-pitched-tone speaker 30 is fixed on the part 63 so that its cone faces forward. When the front panel 52 is fixed in the frame 54, an expansive part 56 covers the front opening of the part 63, transmitting high-sound-pressure sounds, immediately after the sounds are forward emitted from the cone of the speaker 30, to the expansive part 56.
