PROBLEM TO BE SOLVED: To appropriately release a low-pitched sound used for the presentation in a game to a player playing the game in front of a game machine frame. SOLUTION: In the optimal embodiment as illustrated in the figure a and in the Fig. b, a space F illustrated as a screened part is formed in front of a speaker mounted part 81, and the front space E inside a speaker set part 63 in the optimum embodiment is wider outward in the radial direction than the front space E1 inside the contrastive speaker set part 63 indicated in the Fig. c and the Fig. d. Accordingly, the volume of the front enclosure for a low-pitched sound speaker 30 (not illustrated) can be secured large in the front inside the speaker set part 63. COPYRIGHT: (C)2007,JPO&INPIT
