PROBLEM TO BE SOLVED: To provide a game machine capable of clearly providing players with sound and in-shop broadcast related to the game, and allowing the players to select the way of listening to the sound related to the game. SOLUTION: In the game machine, if it is determined that the mode to be changed whenever a speaker switching button is pressed is not a bone-conduction mode (but a sound output mode) (C1:No), the sound (BGM or announcement sound) at the normal volume is output from a speaker (C5). On the other hand, if it is determined that the current mode is the bone-conduction mode (not the sound output mode) (C1:Yes), the sound (BGM or announcement sound) at the volume smaller than the normal volume is output from the speaker and a bone-conduction speaker is vibrated (C10).
