PROBLEM TO BE SOLVED: To provide a game machine which can emit a clear sound toward the player's head without decreasing rigidity of a window frame. SOLUTION: A diaphragm 68 is provided in the window frame 60. The diaphragm 68 constitutes a front wall of a sound box 70; a sound pressure acts on the diaphragm 68 via air in the sound box 70 from an acoustic passage 72 when a speaker 75 is driven; and the sound is emitted from the diaphragm 68. In such a constitution, since the diaphragm 68 is arranged near the player's head in a state in which the he/she seats himself/herself, the sound is emitted toward his/her head. Additionally, since a sound-insulating object is eliminated ahead of the diaphragm 68, articulation of the sound is enhanced. Thus, since a through-hole-shaped sound-emitting port does not have to be formed in the window frame 60, generally, the clear sound can be emitted toward the player's head without decreasing the rigidity of the window frame 60.
