PROBLEM TO BE SOLVED: To provide a game machine in which a sound presentation with a big sound volume is enabled without requiring an unnecessarily wide occupancy space, while suppressing a heat generation in power amplifiers.SOLUTION: When a prescribed winning state related to operation of a player is generated, a game machine generates a game state advantageous to the player on the basis of a winning/losing lottery caused thereby. The game machine is configured by comprising: a main control part 21 for controlling game operation in general including the winning/losing lottery; and sound presentation parts 22, 27 for realizing a sound presentation operation on the basis of a control command CMD from the main control part 21. The sound presentation part is configured by including: two power amplifier parts performing a separate power amplification on a single sound signal, having a same characteristic; and a single speaker SPd for receiving amplified outputs of the two power amplifier parts. Heat generation in each power amplifier part is suppressed by a common and parallel connection of the two power amplifier parts' output terminal on the one side and the output terminal on the other side with the speaker's connection terminal on the one side and the connection terminal on the other side respectively.SELECTED DRAWING: Figure 7 |
