PROBLEM TO BE SOLVED: To provide a game machine capable of implementing further powerful sound performance without complicating a circuit configuration.SOLUTION: A performance control section 22 for executing a sound performance comprises: a one-chip microcomputer 40; a sound synthesis circuit 42 for reproducing a sound signal; a digital amplifier 46 for receiving the sound signal reproduced by the sound synthesis circuit 42 through a serial circuit; and a speaker for receiving outputs of the digital amplifier 46; and is configured to execute a pan-pot performance in a prescribed game state. The sound synthesis circuit 42 and the digital amplifier 46 are connected by a first signal line SD0, a second signal line SD1, a third signal line for transmitting a control signal LRO for specifying the sound signal transmitted by the first signal line and the second signal line, and a fourth signal line for transmitting a clock signal BCO for prescribing transmission timing of the sound signal. |
