Gaming machine and volume control method thereof

Abstract

A gaming machine comprises a sound signal output device, a plurality of attenuators, a signal bus and a speaker. The sound signal output device outputs plural sound signals including a BGM signal and a game effect sound signal in parallel. The attenuator attenuates at least the BGM signal of the plural sound signals outputted from the sound signal output device. The signal bus is adapted to input all the plural sound signals including the BGM signal attenuated in the attenuator and transmits the sound signals. The speaker converts the sound signals transmitted through the signal bus into sound waves and then turns up the sound waves.

1 . A gaming machine comprising:
 a sound signal output device for outputting plural sound signals in parallel;   a plurality of attenuators for attenuating each of the sound signals outputted from the sound signal output device, respectively;   a signal bus adapted to input the sound signals attenuated in the attenuators therein and transmitting the sound signals; and   a speaker for converting the sound signals transmitted via the signal bus into sound waves and turning up the sound waves.   
   
   
       2 . A gaming machine comprising:
 a sound signal output device for outputting plural sound signals in parallel;   a signal bus adapted to input any of the sound signals outputted from the sound signal output device therein and transmitting the sound signals;   an attenuator for attenuating the sound signals transmitted through the signal bus;   an adder for adding the sound signals attenuated by the attenuator and the sound signal outputted from the sound signal output device; and   a speaker for converting the sound signal added into a sound wave and turning it up.   
   
   
       3 . A gaming machine comprising:
 a sound signal output device for outputting plural sound signals including a BGM signal and a game effect sound signal, in parallel;   a plurality of attenuators for attenuating at least the BGM signal of the plural signals outputted from the sound signal output device;   a signal bus adapted to input all the plural sound signals including the BGM signal attenuated by the attenuator therein and transmitting the sound signals; and   a speaker for converting the sound signals transmitted via the signal bus into sound waves and turning up the sound waves.   
   
   
       4 . A gaming machine comprising:
 a sound signal output device for outputting plural sound signals including a BGM signal and a game effect sound signal, in parallel;   a signal bus adapted to input the plural BGM signals outputted from the sound signal output device therein and transmitting the BGM signals;   an attenuator for attenuating the BGM signals transmitted through the signal bus;   an adder for adding the BGM signal attenuated by the attenuator and the game effect sound signal outputted from the sound signal output device; and   a speaker for converting the sound signal added into a sound wave and turning it up.   
   
   
       5 . A volume control method of a gaming machine comprising:
 attenuating each of plural sound signals, respectively;   enabling the plural sound signals attenuated to be inputted into a signal bus; and   converting and turning up the sound signals into sound waves.   
   
   
       6 . A volume control method of a gaming machine comprising:
 enabling any of plural sound signals to be inputted into a signal bus;   attenuating the sound signal transmitted through the signal bus;   adding the sound signal attenuated and the sound signal not attenuated; and   converting and turning up the sound signal added into a sound wave.   
   
   
       7 . A volume control method of a gaming machine comprising:
 attenuating at least BGM signal of plural sound signals including the BGM signal and a game effect sound signal;   enabling all the plural sound signals including the attenuated BGM signal to be inputted into a signal bus; and   converting and turning up the sound signals transmitted through the signal bus into sound waves.   
   
   
       8 . A volume control method of a gaming machine comprising:
 enabling a BGM signal of plural signals including the BGM signal and a game effect sound signal to be inputted into a signal bus;   attenuating the BGM signal transmitted through the signal bus;   adding the BGM signal attenuated and the game effect sound signal not attenuated; and   converting and turning up the added sound signal into a sound wave.
