PROBLEM TO BE SOLVED: To appropriately provide low-pitched sound on the front side of a game machine frame relating to a game acoustic device. SOLUTION: Sound emitted from a low-pitched sound speaker 30 to the front side passes successively from the front side of a speaker installation part 63 through a closed space D, a bass reflex duct part 72, a bass reflex opening 55 and a low-pitched sound emitting hole part 50 and is emitted from the left and right lower part of the front door 4 to the front side by a transmission path indicated by the arrow X1 of the sound by the vibration of air. The sound emitted from the low-pitched sound speaker 30 to the rear side passes successively from the back side of the speaker installation part 63 through a speaker rear cover 90, a sound emitting hole part 92 and a speaker escape part 46 and is emitted to the rear side of a game board 36 by a transmission path indicated by the arrow X2 of the sound by the vibration of air, and the low-pitched sound emitted to the front side of the low-pitched sound speaker 30 is not offset by the low-pitched sound emitted to the rear side of the low-pitched sound speaker 30.
