<P>PROBLEM TO BE SOLVED: To prevent damage to a sound control unit when over current is caused by separation of a connector in a game machine where a speaker and the sound control unit are connected by a drawer connecter. <P>SOLUTION: The game machine has: a speaker 10 provided to an outer frame 2; the sound control unit 300 which is provided to an intermediate frame 3 and outputs an audio signal to the speaker 10; the drawer connector 301 which has an intermediate frame side connector 301a that is provided to the intermediate frame 3 and is electrically connected to the sound control unit 300 and an outer frame side connector 301b that is provided to the outer frame 2 and is electrically connected to the speaker 10, and enables the intermediate frame side connector 301a and the outer frame side connector 301b to be electrically separated and connected by opening/closing of the intermediate frame 3 with respect to the outer frame 2; and a protective circuit 303 provided to wiring which connects the sound control unit 300 and the intermediate frame side connector 301a. In the protective circuit 303, impedance becomes low, as the frequency of the audio signal becomes high, in the frequency band of the audio signal output by the sound control unit 300. <P>COPYRIGHT: (C)2012,JPO&INPIT |
