As described above, if the gaming state of the gaming machine is in the normal state or the special prize state while the sound volume is small, the CPU 5 causes the CPU 5 to execute steps S104 and S1.
Through 06, the output ports PA0 and PA1 are both turned off, and a low-level control signal is output from the output ports PA0 and PA1. Then, since the control signal from the volume setting switch 70 is at a high level, a high-level control signal is input to the TONE terminal 14, and the loudness control is enabled. Since the control signal from the volume setting switch 70 is at a high level and the control signal from the output port PA1 is at a low level, the selectors 23 and 26 select the loudness constant A setting circuits 21 and 24. Therefore, based on the loudness constant A, the audio signal processing circuit 10 increases the spectrum of the audio signal from the output terminals 17 and 18 in the high frequency band and the low frequency band as compared with the other frequency bands. Output terminal 17,
The spectrum of the audio signal 18 is adjusted according to the spectrum adjustment characteristic as shown in FIG.

On the other hand, since the control signal from the output port PA0 is at a low level, no adjustment is made for the phase difference and the level difference between the audio signals from the output terminals 17 and 18. Thus, when the gaming volume of the gaming machine is in the normal state or the special prize state when the audio volume is small, the output audio can be sharpened, and the difficulty in listening due to the small audio volume can be reduced. it can.

On the other hand, if the gaming state of the gaming machine is a high-probability reach state or a special prize state when the sound volume is low, the CPU 5 causes the CPU 5 to execute step S11.
After S2 and S114, both output ports PA0 and PA1 are turned on, and a high-level control signal is output from output ports PA0 and PA1. Then, since the control signal from the volume setting switch 70 is at a high level, a high-level control signal is input to the TONE terminal 14, and the loudness control is enabled. Since the control signal from the volume setting switch 70 is at a high level and the control signal from the output port PA1 is at a high level, the selectors 23 and 2
6, the loudness constant B setting circuits 22 and 25 are selected. Therefore, based on the loudness constant B, the audio signal processing circuit 10 increases the spectrum of the audio signal from the output terminals 17 and 18 in the high frequency band and the low frequency band as compared with the other frequency bands. Output terminal 1
The spectrum of the audio signals from 7 and 18 is adjusted according to the spectrum adjustment characteristics as shown in FIG.

On the other hand, since the control signal from the output port PA0 is at a high level, the audio signal processing circuit 10 causes the phase difference and the level difference of each audio signal from the output terminals 17 and 18 at a plurality of frequencies. Staggered. With this, when the audio volume is low, when the gaming state of the gaming machine is the start of the reach state or the special state with a high probability, the output sound is further added to the output state as compared with the case where the normal state or the special state is in progress. It can give a sense of sharpness and a more widespread stereo feeling. Therefore, it is possible to reduce the difficulty of hearing due to the low sound volume and to emphasize the appeal to the player as compared with the case where the normal state or the special prize state is in progress. Can be.

Next, the volume setting switch 70 is set to the second contact
The case of switching to the side will be described. Volume setting switch 70
Is switched to the second contact side, the low-level control signal
The switch opening / closing devices 34 and 38 are both turned off
Becomes non-conductive between the switch opening / closing devices 34 and 38
Becomes As a result, the voltage dividing resistor on the L output terminal 17 side becomes
(R_Two+ R_Three) / (R₁+ R_Two+ R _Three) And the first contact
It becomes larger than when switching to the side. Audio signal processing times
Of the audio signals from the road 10, those from the L output terminal 17
For, the voltage is divided by the voltage dividing resistor
As a result, the sound signal is
Attenuation is reduced. Also, the voltage dividing resistor on the R output terminal 18 side
Is (R_Five+ R₆) / (R_Four+ R_Five+ R₆) And the first
It becomes larger than when switching to the contact side. Audio signal processing
Of the audio signal from the logical circuit 10 from the R output terminal 18
The voltage is divided by the above-mentioned voltage-dividing resistor.
The voice signal is higher than when switching to the first contact side.
Signal attenuation is reduced.

Therefore, the volume setting switch 70 is set to the second
When the contact is switched to the contact side, the sound volume increases because the voltage dividing resistance increases. As described above, when the gaming state of the gaming machine is in the normal state or the special prize state while the sound volume is large, the CPU 5 turns off both the output ports PA0 and PA1 through steps S104 and S106, and A low-level control signal is output from ports PA0 and PA1. Since the control signal from the volume setting switch 70 is also at a low level, a low-level control signal is input to the TONE terminal 14, and the loudness control is invalidated. Therefore, output terminal 1
No adjustment is made to the spectrum of the audio signals from 7 and 18.

On the other hand, since the control signal from the output port PA0 is at a low level, no adjustment is made for the phase difference and the level difference between the audio signals from the output terminals 17 and 18. Thus, when the audio volume is large and the gaming state of the gaming machine is in the normal state or the special prize state, the output audio is output as it is. That is, the output is performed as usual.

On the other hand, if the gaming state of the gaming machine is a high-probability reach state or a special prize state when the sound volume is large, the CPU 5 causes the CPU 5 to execute step S11.
After S2 and S114, both output ports PA0 and PA1 are turned on, and a high-level control signal is output from output ports PA0 and PA1. Since the control signal from the output port PA1 is at a high level, a high-level control signal is input to the TONE terminal 14, and the loudness control is enabled. Since the control signal from the volume setting switch 70 is at a low level and the control signal from the output port PA1 is at a high level, the selectors 23 and 26 select the loudness constant A setting circuits 21 and 24. Therefore, based on the loudness constant A, the audio signal processing circuit 10 increases the spectrum of the audio signal from the output terminals 17 and 18 in the high frequency band and the low frequency band as compared with the other frequency bands. Output terminal 17,
The spectrum of the audio signal 18 is adjusted according to the spectrum adjustment characteristic as shown in FIG.

On the other hand, since the control signal from the output port PA0 is at a high level, the audio signal processing circuit 10 causes the phase difference and the level difference of the audio signals from the output terminals 17 and 18 to be different at a plurality of frequencies. Staggered. Thus, when the gaming volume of the gaming machine is a high-probability reach state or the start of a prize state when the sound volume is large, the output sound is sharper than when the normal state or the prize state is in progress.

Is made larger than the other frequency bands, and the phase difference and the level difference between the left and right output voices in stereo are shifted in a plurality of frequency bands.

As a result, the output sound can be sharpened, so that the output sound can be heard relatively easily even if the volume of the output sound is reduced. This is because human hearing has a high frequency band (for example, about 10 kHz or more) and a low frequency band (for example,
This is because the sensitivity has a characteristic that the sensitivity is particularly lowered as compared with that in the middle frequency band.

Further, in this embodiment, when the audio volume is small and the gaming state of the gaming machine is a high-probability reach state or the start of a special prize state, the high frequency of the output audio is determined based on the loudness constant B. The spectrums of the band and the low frequency band are made larger than those of the other frequency bands, and the phase difference and the level difference between the left and right output sounds of the stereo are shifted in a plurality of frequency bands.

As a result, the output sound can be provided with a sharper feeling and a wider stereo feeling than when the normal state or the special prize state is in progress. Therefore, even if the volume of the output sound is reduced, the listening of the output sound becomes relatively easy,
The appeal to the player can be emphasized more than when the normal state or the special prize state is in progress, so that the effect can be relatively enhanced.
