PROBLEM TO BE SOLVED: To provide a low-pitched sound speaker system for a game machine which does not spoil the external appearance of the front of the game machine by openings for discharging sound effects and which does not narrow the freedom degree of the mounting position to the game machine. SOLUTION: A Kelton type enclosure is used for an enclosure 2. The opening diameter d of a sound effect discharging port (the port 6) is set to a smaller size about a fraction of the diameter D of a diaphragm 1a of the speaker 1. The opening for discharging the sound effects in the front of the game machine is made smaller. The port of the enclosure is formed into an appropriate shape such as a linear shape and an L shape. The opening end 6a of the port is made to communicate with an opening 7 for discharging the sound effects formed at a desired place on the front side of the game machine. COPYRIGHT: (C)2004,JPO&NCIPI
