The device 38 and other performance devices are controlled. Further, the sub-control board 72 receives input signals from input means such as the performance button 62 and the performance operation section 57, performs various calculations related to the performance, advances the performance, and changes settings related to the performance. or That is, the sub-control board 72 controls the performance.

The main control board 70 and the sub-control board 72 are electrically connected, and it is possible to send various information (commands) such as information indicating the gaming status from the main control board 70 to the sub-control board 72. , information cannot be transmitted from the sub-control board 72 to the main control board 70.
In addition, the functions of each board such as the main control board 70 and the sub-control board 72 are preset in hardware such as various processors (CPU, DSP, etc.), ICs, or information storage media such as ROM and RAM, and ROM, etc. This is realized by software consisting of a predetermined stored program.

The sub-control board 72 mainly controls various performances such as during gaming and on standby. The sub-control board 72 includes a performance control section (performance control means) 74, a performance sound control section (performance sound control means) 76, a storage section (storage means) 78, and an amplifier group 112. In this embodiment, the effect control section 74 and the effect sound control section 76 are configured as one circuit (for example, integrated into one package or one chip), and are also configured as a functional block of this circuit.

As shown in FIG. 1, the gaming machine of this embodiment has two speakers (lower speakers 100a, 100b) provided on the lower door 40 and two speakers (upper speakers 100c, 100d) provided on the upper door 30. ). That is, the front door 12 is provided with lower speakers 100a, 100b and upper speakers 100c, 100d arranged above the lower speakers 100a, 100b. Further, the two lower speakers 100a and 100b are placed apart from each other in the left and right directions, and are also placed at approximately the same position (height) in the vertical direction. Further, the two upper speakers 100c and 100d are spaced apart from each other in the left and right directions, and are also arranged at approximately the same position (height) in the vertical direction. Note that in this specification, substantially the same (substantially identical) includes the case of being the same (same). That is, the gaming machine of this embodiment has four speakers whose relative positions are a speaker 100a at the lower left, a speaker 100b at the lower right, a speaker 100c at the upper left, and a speaker 100d at the upper right. It has two speakers. In other words, when viewed from the player when playing a game, there are four speakers: a speaker 100a located at the lower left, a speaker 100b located at the lower right, a speaker 100c located at the upper left, and a speaker 100d located at the upper right. have.

Furthermore, the gaming machine of this embodiment has two tweeters 100e and 100f provided on the upper door 30. Further, the tweeters 100e and 100f are arranged above the upper speakers 100c and 100d. Further, the two tweeters 100e and 100f are spaced apart from each other in the left and right directions, and are also arranged at substantially the same position (height) as each other in the vertical direction.

The two lower speakers 100a and 100b, the two upper speakers 100c and 100d, and the two tweeters 100e and 100f are speakers with different specifications (speakers with different model numbers). In other words, the lower speakers 100a, 100b, the upper speakers 100c, 100d, and the tweeters 100e, 100f have different reproducible frequency bands (reproduction frequency band (rated frequency band): frequency characteristics). In other words, the frequency characteristics of the output sound pressure level are different between the lower speakers 100a and 100b, the upper speakers 100c and 100d, and the tweeters 100e and 100f.

The lower speakers 100a and 100b have larger diaphragm areas (diameters) than the upper speakers 100c and 100d. Specifically, the diaphragms of the lower speakers 100a, 100b are circular and have a diameter of about 10 cm. The diaphragms of the upper speakers 100c and 100d are oval in shape, with a major axis of approximately 10 cm and a minor axis of approximately 4.5 cm. Therefore, the lower speakers 100a and 100b can also be said to be large speakers. Moreover, the upper speakers 100c and 100d can also be said to be small speakers. Furthermore, the tweeters 100e and 100f have smaller diaphragm areas (diameters) than the upper speakers 100c and 100d. Specifically, the diaphragms of the tweeters 100e and 100f are circular and have a diameter of about 2.5 cm. Therefore, the tweeters 100e and 100f can be said to be the smallest speakers.

As shown in FIG. 3, the reproduction frequency band of the lower speakers 100a and 100b is 90Hz to 16kHz. Further, the lowest resonant frequency of the lower speakers 100a and 100b is 90 Hz. Furthermore, the reproduction frequency band of the upper speakers 100c and 100d is 235 Hz to 18 kHz. Further, the lowest resonance frequency of the upper speakers 100c and 100d is 235 Hz. Furthermore, the reproduction frequency band of the tweeters 100e and 100f is 2 kHz to 20 kHz. Further, the lowest resonant frequency of the tweeters 100e and 100f is 2 kHz. The lower speakers 100a, 100b and the upper speakers 100c, 100d can output sound in a wider range (wider reproduction frequency band) than other speakers such as tweeters and woofers, and can be said to be full-range speakers.

Further, the lower speakers 100a, 100b and the upper speakers 100c, 100d have a common reproduction frequency band of 235 Hz to 16 kHz (frequency band A). In addition, the lower speakers 100a, 100b, the upper speakers 100c, 100d, and the tweeters 100e, 100f have a common reproduction frequency band of 2 kHz to 16 kHz (frequency band B). Furthermore, the upper speakers 100c and 100d and the tweeters 100e and 100f have a common reproduction frequency band of 2 kHz to 18 kHz (frequency band C). Further, the lower speakers 100a, 100b and the tweeters 100e, 100f have a common reproduction frequency band of 2 kHz to 16 kHz (frequency band D). Further, regarding the bandwidth (frequency range), frequency band C is wider than frequency band A, and frequency band A is wider than frequency band B.

As shown in FIG. 2, the effect sound control section 76 can control the speakers 100a, 100b, 100c, 100d, 100e, and 100f via amplifiers 113, 114, and 115 that constitute the amplifier group 112. Further, the amplifiers 113, 114, and 115 convert the signal output from the effect sound control section 76 from a digital signal to an analog signal, and amplify this analog signal to output the signal to the speakers 100a, 100b, 100c, 100d, 100e, and 100f. It is now possible to drive. In other words, the amplifiers 113, 114, and 115 function as a DAC (digital-to-analog converter) and also as an amplifier (for example, a class D amplifier). Further, each of the amplifiers 113, 114, and 115 is configured as one circuit (for example, one package or one chip). For this reason, the plurality of amplifiers 113, 114, 115 and the sound effect control section 76 are composed of different components (electronic components such as integrated circuits in a broad sense, chip components provided in integrated circuits in a narrow sense). . Specifically, in the gaming machine of this embodiment, the performance control section 74 and the performance sound control section 76 are configured by the main IC (performance control IC) of the sub-control board 72, while the amplifiers 113, 114, 115 is constituted by an amplifier IC separate from the production control IC, and the plurality of amplifiers 113, 114, 115 and the production sound control section 76 are mutually different ICs. Further, the amplifiers 113, 114, and 115 are all ICs with the same specifications (ICs with the same model number).

As shown in FIG. 4, the effect sound control section 76 includes a decoder section 150, a first volume control section 151, a second volume control section 153, an equalizer section (frequency characteristic control section) 155, and a third volume control section. section 157 and an audio output section 159. In addition, the effect sound control unit 76 controls a plurality of tracks (for example, a total of 40 tracks from track 1 to track 40) and a plurality of tracks (for example, a total of 8 tracks from channel CH1 to channel CH8 (CH7 and CH8 are not shown)). channels. Here, a track is an execution unit for reproducing each performance sound (phrase data) stored in the performance sound storage unit (ROM) 160 of the storage unit 78, and a channel is an execution unit of the performance sound data of the performance sound control unit 76. It is an output unit. The effect sound control section 76 is configured to synthesize the effect sounds (output of each track) played on each track in each channel and output the synthesized sound.
Note that the performance sound storage unit 160 stores performance sounds such as a series of background music (BGM), preview sounds, sound effects, character dialogue sounds, and the like.

In addition, in the following explanation, the volume setting value is set in 256 levels from "0" to "255", and the volume "0" is silent and the volume "255" is the maximum volume, but there are no particular limitations regarding each setting value or the number of stages. It's not something you do.

The decoder section 150 is capable of independently decoding each track. Thereby, the effect sound control section 76 can simultaneously reproduce up to 40 effect sounds (the effect sounds read from the effect sound storage section 160). The effect sound of each track that has been decoded by the decoder section 150 is input to the first volume control section 151.

The first volume control section 151 is capable of adjusting the volume for each track. Furthermore, the first volume control section 151 is capable of adjusting the volume of each track for each output destination channel. That is, for example, if BGM is played on track 1 and a character's dialogue sound is played on track 2, the volume of the BGM played on track 1 is set to "100", and the character's dialogue sound is played on track 2. It is possible to set different volume settings for each track, such as setting the sound volume to "150". You can also set the volume for each output channel, for example, output the BGM played on track 1 to channel CH1 with a volume of "100" and to channel CH2 with a volume of "50". It is possible to make them different.

The reproduced sound on each track is output to each channel at a volume according to the setting of the first volume control section 151, and is synthesized (superimposed) on each channel. That is, each channel handles a performance sound (synthesized performance sound) that is a composite of the performance sounds of each track. The effect sound of each channel (synthesized effect sound) obtained by combining the outputs of the first volume control section 151 is input to the second volume control section 153.

The second volume control section 153 is capable of adjusting the volume for each channel. Then, the synthesized sound of each channel whose volume is adjusted by the second volume control section 153 is input to the equalizer section 155.

The equalizer section 155 is capable of realizing desired frequency characteristics for each channel. Specifically, the equalizer section 155 is capable of strengthening or weakening a predetermined frequency band of the synthesized sound according to settings. In other words, the equalizer section 155 is capable of increasing or decreasing the volume (sound pressure level) of the synthesized effect sound for each frequency band. In other words, the equalizer section 155 can set the input/output gain for each frequency band of the synthesized effect sound. It can also be said that the equalizer section 155 functions as a filter circuit (digital filter). That is, the first volume control section 151, the second volume control section 153, and the third volume control section 157 control the production sound of each track or each channel in all frequency bands (at least the audible band or the reproduction frequency band of the corresponding speaker 100). In contrast, the equalizer section 155 can increase or decrease the volume (gain) of a predetermined band included in the audible band (the reproduction frequency band of the speaker 100). It is possible.

The synthesized sound of each channel that has passed through the equalizer section 155 is input to the third volume control section 157. The third volume control section 157 is capable of uniformly adjusting the volume for all channels. That is, depending on the settings of the third volume control section 157, the volume of all channels is uniformly increased or decreased.

The audio output section 159 is configured to be able to output a bit clock signal BCLK, a word clock signal LRCLK, and a serial data signal SDATA that conform to the I2S (Inter-IC Sound) standard, for example. The audio output section 159 is configured to output the synthesized effect sound of each channel output from the third volume control section 157 in a method compliant with the I2S standard. The gaming machine of this embodiment is capable of outputting a plurality of serial data signals SDATA including a first serial data signal SDATA1, a second serial data signal SDATA2, and a third serial data signal SDATA3. The first serial data signal SDATA1 includes data of the synthesized effect sound of channel CH1 and channel CH2, and the second serial data signal SDATA2 includes data of the synthesized effect sound of channel CH3 and channel CH4, The third serial data signal SDATA3 includes data of synthesized effect sounds of channels CH5 and CH6.

The bit clock signal BCLK, word clock signal LRCLK, and serial data signal SDATA output from the audio output section 159 are input to the amplifier group 112, as shown in FIG. Specifically, the bit clock signal BCLK, the word clock signal LRCLK, and the first serial data signal SDATA1 are input to the amplifier 113, and the bit clock signal BCLK, the word clock signal LRCLK, and the second serial data signal SDATA2 are input to the amplifier 114. The bit clock signal BCLK, the word clock signal LRCLK, and the third serial data signal SDATA3 are input to the amplifier 115.

The amplifier 113 drives the speaker 100a and the speaker 100b to output sound based on the first serial data signal SDATA1 sent from the performance sound control section 76. The word clock signal LRCLK and the first serial data signal SDATA1 are synchronized, and when the word clock signal LRCLK is at a low level, the first serial data signal SDATA1 including the data of the synthesized sound of the channel CH1 is transmitted, When the word clock signal LRCLK is at High level, the first serial data signal SDATA1 including the data of the synthesized effect sound of the channel CH2 is transmitted. The amplifier 113 causes the speaker 100a to output sound effects based on the first serial data signal SDATA1 input when the word clock signal LRCLK is at a low level. Further, the amplifier 113 causes the speaker 100b to output sound effects based on the first serial data signal SDATA1 input when the word clock signal LRCLK is at a high level. Therefore, the speaker 100a outputs the synthesized effect sound of channel CH1, and the speaker 100b outputs the synthesized effect sound of channel CH2.

The amplifier 114 drives the speaker 100c and the speaker 100d to output sound based on the second serial data signal SDATA2 sent from the performance sound control section 76. The word clock signal LRCLK and the second serial data signal SDATA2 are synchronized, and when the word clock signal LRCLK is at a low level, the second serial data signal SDATA2 including the data of the synthesized sound of channel CH3 is transmitted, When the word clock signal LRCLK is at a high level, the second serial data signal SDATA2 containing the data of the synthesized effect sound of the channel CH4 is transmitted. The amplifier 114 causes the speaker 100c to output sound effects based on the second serial data signal SDATA2 input when the word clock signal LRCLK is at a low level. Furthermore, the amplifier 114 causes the speaker 100d to output sound effects based on the second serial data signal SDATA2 input when the word clock signal LRCLK is at a high level. Therefore, the synthesized effect sound of channel CH3 is output from the speaker 100c, and the synthesized effect sound of channel CH4 is output from the speaker 100d.

The amplifier 115 drives the speaker 100e and the speaker 100f to output sound based on the third serial data signal SDATA3 sent from the performance sound control section 76. The word clock signal LRCLK and the third serial data signal SDATA3 are synchronized, and when the word clock signal LRCLK is at a low level, the third serial data signal SDATA3 including the data of the synthesized sound of channel CH5 is transmitted, When the word clock signal LRCLK is at a high level, the third serial data signal SDATA3 including the data of the synthesized effect sound of the channel CH6 is transmitted. The amplifier 115 causes the speaker 100e to output sound effects based on the third serial data signal SDATA3 input when the word clock signal LRCLK is at a low level. Furthermore, the amplifier 115 causes the speaker 100f to output sound effects based on the third serial data signal SDATA3 inputted when the word clock signal LRCLK is at a high level. Therefore, the synthesized effect sound of channel CH5 is output from the speaker 100e, and the synthesized effect sound of channel CH6 is output from the speaker 100f.

In the gaming machine of this embodiment, the equalizer section 155 includes a first equalizer section 155a and a second equalizer section 155b. The first equalizer section 155a and the second equalizer section 155b are configured to change the frequency characteristics of the effect sound according to the frequency characteristics (frequency response) set respectively. In other words, the first equalizer section 155a and the second equalizer section 155b are digital filters each having frequency characteristics (frequency response) according to their settings.

The first equalizer section 155a adjusts the frequency characteristics ( frequency response) is set. That is, the sound that is input to the decoder section 150 and output from the speaker 100 is normally reproduced depending on the frequency characteristics of the speaker 100, the influence of the circuit that drives the speaker 100, the shape of the part (enclosure) that houses the speaker 100, etc. A predetermined frequency component within the frequency band will be attenuated. The first equalizer unit 155a performs processing to correct changes in the frequency characteristics of the effect sound due to these factors. Specifically, the first equalizer section 155a has an input-to-output gain characteristic that is substantially uniform (flat) over substantially the entire reproduction frequency band of each speaker for the sound that is input to the decoder section 150 and output from each speaker 100. A process (equalization process) is performed to make it as follows.

Note that the settings of the first equalizer section 155a that can realize such equalization processing include, for example, inputting white noise to the decoder section 150 and outputting it from the speaker 100, and then inputting the sound output from the speaker 100 to a microphone. Collect sound, and adjust the settings (frequency response) of the first equalizer section 155a so that the frequency characteristics of the collected output sound are flat (so that the volume of the output sound is uniform in a predetermined frequency range). This can be achieved by Specifically, for example, when white noise is input to the decoder section 150 and output from the speaker 100 without being corrected by the first equalizer section 155a, the frequency characteristics of the output sound are shown in FIGS. 5(a) and 5(b). ), the first equalizer section 155a is set so that the frequency characteristics of the output sound are as shown by the broken lines in FIGS. 5(a) and 5(b). Note that FIG. 5(a) shows the frequency characteristics of the output sound in the normal mode, which will be described later, and FIG. 5(b) shows the frequency characteristics of the output sound in the treble cut mode, which will be described later.

Note that the first equalizer section 155a can adjust settings for each speaker (each channel). In the gaming machine of this embodiment, the lower speakers 100a and 100b (channels CH1 and CH2), the upper speakers 100c and 100d (channels CH3 and CH4), and the tweeters 100e and f (channels CH5 and CH6) are different from each other. It is now considered a setting. Note that the settings of the first equalizer section 155a for each channel are adjusted so that the gain characteristics from the input of the decoder section 150 to the output of the speaker 100 are approximately uniform throughout the reproduction frequency band of the corresponding speaker 100. Alternatively, the gain characteristics may be adjusted so that the gain characteristics of the corresponding speaker 100 are approximately uniform in a predetermined frequency range in which the gain characteristics are desired to be approximately uniform.

Further, the effect sound control section 76 is capable of changing the setting of the second equalizer section 155b based on the user's operation on the effect operation section 57. In the gaming machine of this embodiment, for the performance sound output from a predetermined speaker 100, there is a treble cut mode in which components of a predetermined frequency or higher are suppressed (attenuated), and a high-pitched sound cut mode in which components of a predetermined frequency or higher are not suppressed (not attenuated). ) A plurality of (at least two) modes (effect sound modes) including a normal mode are provided. That is, in the treble cut mode, the amount of attenuation of the components of the effect sound above a predetermined frequency is greater than in the normal mode. Then, the effect sound control section 76 changes the settings of the second equalizer section 155b according to the mode so that the second equalizer section 155b has a desired frequency characteristic (frequency response) according to the mode. There is.

Note that switching between the normal mode and the treble cut mode may be performed in the same manner as the volume setting in a general gaming machine, for example. That is, for example, based on the player's operation, a screen may be displayed on the liquid crystal display 34 for selecting a mode related to the effect sound, and the mode may be selected by operating the cross key or enter button of the effect operation section 57. .

The frequency characteristics (input vs. output gain characteristics) of the second equalizer section 155b in the normal mode are shown in FIG. 6(a). Further, the frequency characteristics (input vs. output gain characteristics) of the second equalizer section 155b in the treble cut mode are shown in FIG. 6(b). As shown in FIG. 6A, in the normal mode, the frequency characteristics of the second equalizer section 155b are flat over the entire band. In other words, in the normal mode, the second equalizer section 155b has a gain of 0 dB over the entire reproduction frequency band of the speakers 100a, 100b, 100c, 100d, 100e, and 100f. In other words, in the normal mode, the second equalizer section 155b has a gain of 0 dB in the band from 200 Hz to 20 kHz. That is, in the normal mode, the second equalizer section 155b does not change the frequency characteristics of the effect sound that passes through it, and allows it to pass through as is.

Further, as shown in FIG. 6B, in the treble cut mode, the second equalizer section 155b has a gain of less than 0 dB in a band of a specific frequency (for example, 3 kHz) or higher. Further, in a band below a specific frequency, the gain is 0 dB. In other words, in the treble cut mode, the second equalizer section 155b is designed to attenuate components of a specific frequency or higher of the passing performance sound. In other words, in the treble cut mode, the second equalizer section 155b performs low-pass filter processing on the performance sound, allowing components below a specific frequency to pass through without attenuation, while attenuating (cutting) components above a specific frequency. ).

Here, the specific frequency in the second equalizer section 155b is preferably set to 3 kHz or more. Further, the specific frequency is preferably set to 10 kHz or less, more preferably 8 kHz or less, and even more preferably 6 kHz or less. By setting the specific frequency in this way, it becomes possible to remove sounds that are highly irritating to the ears. Note that in the example shown in FIG. 6(b), the specific frequency is set to 3 kHz, and the cutoff frequency is set to approximately 6 kHz.

Further, the specific frequency is set to a higher frequency than the test tone. Here, the test tone is a sine wave sound (sine wave signal) of a single frequency, and is a signal for testing the sound output. The gaming machine of this embodiment is capable of outputting a plurality of types of test tones; for example, a 500 Hz test tone and a 1 kHz test tone are prepared. Specifically, data of a 500 Hz test tone is stored in the storage unit 78, and the effect sound control unit 76 is able to output a 500 Hz test tone from each speaker 100 based on the data. ing. Furthermore, the effect sound control section 76 has a signal generator (oscillator) and is capable of generating a 1 kHz test tone. A 1 kHz test tone generated by the signal generator can be input to each channel and output from each speaker 100. The specific frequency is preferably set to a higher frequency than at least one of the test tones that the slot machine X can output, and is set to a higher frequency than all the test tones that the slot machine X can output. Good too. In other words, it is preferable that at least one test tone with a frequency lower than the specific frequency is prepared (stored in the storage means 78 or can be generated by a signal generator), and a plurality of test tones are preferably prepared. It is even more preferable that By preparing at least one test tone with a frequency lower than the specific frequency, it becomes possible to perform the test in the treble cut mode.

In addition, in the treble cut mode, the second equalizer section 155b controls the component of the effect sound output from the speaker 100 that has a specific frequency or above, for at least one of the speakers 100 whose reproduction frequency band includes a frequency that is a specific frequency or above. It is designed to attenuate the In the gaming machine of this embodiment, in the treble cut mode, the second equalizer section 155b controls the frequency of the effect sound output from the speaker 100 to be equal to or higher than the specific frequency for all speakers 100 whose reproduction frequency band includes a frequency equal to or higher than the specific frequency. It is designed to attenuate the components of In other words, when the mode is changed between the normal mode and the treble cut mode, the settings of the second equalizer section 155b are changed for a predetermined speaker (predetermined channel). Note that when the mode is changed between the normal mode and the treble cut mode, the settings of the second equalizer section 155b may be changed for all channels, and the settings of the second equalizer section 155b may be changed for some channels. The settings may not be changed, or may be set differently for each channel (specific frequencies may be different).
Note that the gaming machine may include a woofer (speaker 100) that outputs sounds in a lower range than the lower speakers 100a and 100b. Here, the woofer is, for example, a speaker whose lower limit and upper limit of the frequency of the reproduction frequency band are lower than those of the lower speakers 100a, 100b, the upper speakers 100c, 100d, and the tweeters 100e, 100f. In this case, if the reproduction frequency band of the woofer includes frequencies above a specific frequency (if the upper limit value is higher than the specific frequency), the effect sound output from the woofer will also include components above the specific frequency. It is also possible to attenuate the

Note that the equalizer section 155 may include a third equalizer section, and the third equalizer section may be configured to attenuate (cut) components below a predetermined frequency of the effect sound. In other words, the equalizer section 155 may include a third equalizer section that performs high-pass filter processing to attenuate (cut) components below a predetermined frequency. Specifically, the third equalizer section may perform processing to attenuate components of 90 Hz or less (or, for example, 100 Hz or less) for the effect sounds output from the lower speakers 100a and 100b, and Regarding the effect sound to be output, processing may be performed to attenuate the component of 235 Hz or less (or, for example, 240 Hz or less), and for the effect sound output from the tweeters 100e and 100f, the component of 2 kHz or less (or, for example, 2020 Hz or less) may be attenuated. You may also perform processing to In other words, the third equalizer section may perform a process of attenuating components of the lowest resonance frequency or lower in the effect sound output from each speaker 100. According to such a configuration, the load on the speaker 100 due to the component of the lowest resonant frequency can be reduced.

Further, the equalizer section 155 has a fourth equalizer section, and the fourth equalizer section is configured to attenuate (cut) components of a second specific frequency or less of the effect sound output from the speaker 100 for a predetermined speaker 100. It may be . For example, the fourth equalizer section may attenuate components of the second specific frequency or lower in the effect sounds (the effect sounds of channels CH3 and CH4) output from the upper speakers 100c and 100d. In other words, the frequency response of the fourth equalizer section may be set so that the gain is less than 0 dB in a band below the second specific frequency. Here, the second specific frequency may be set to, for example, 800 Hz, and at least part of the midrange (for example, 100 Hz to 1 kHz sound range) portion of the effect sound output from the upper speakers 100c and 100d may be attenuated. In other words, the second specific frequency may be set to a higher frequency than the lowest resonance frequency of 235 Hz of the upper speakers 100c and 100d. Further, the second specific frequency may be set to a higher frequency than the lowest resonant frequency of 90 Hz of the lower speakers 100a and 100b. Further, the second specific frequency may be set to a lower frequency than the test tone. More specifically, the second specific frequency is preferably set to a lower frequency than at least one of the test tones that the slot machine X can output, and all test tones that the slot machine X can output. It may be set to a lower frequency. In other words, it is preferable that at least one test tone with a frequency higher than the second specific frequency is prepared (stored in the storage means 78 or can be generated by a signal generator), and it is preferable that a plurality of test tones are prepared. It is further preferable that the By preparing at least one test tone with a frequency higher than the second specific frequency, it is possible to perform an inspection with components of frequencies lower than the second specific frequency cut. According to such a configuration, for the effect sound output from the upper speakers 100c and 100d, which are in charge of outputting relatively high-pitched sounds, the mid-range components are reduced, and the effects are in charge of outputting relatively low-pitched sounds. It is possible to prevent the band from overlapping with the performance sound output from the lower speakers 100a, 100b. As a result, the sound output from the speaker system including the upper speakers 100c and 100d and the lower speakers 100a and 100b can be clearly heard. Furthermore, by eliminating unnecessary band overlap, the load on each speaker 100 can be reduced and the amount of heat generated can be reduced. Furthermore, the load on the upper speakers 100c and 100d due to the lowest resonance frequency component can be reduced.
Note that the processing in the fourth equalizer section may be performed in the third equalizer section. In other words, the predetermined frequency for the upper speakers 100c and 100d in the third equalizer section may be set to the second specific frequency.

Further, the equalizer section 155 has a fifth equalizer section, and the fifth equalizer section is configured to attenuate (cut) components of the effect sound outputted from the speaker 100 at a third specific frequency or lower for a predetermined speaker 100. It may be . For example, the fifth equalizer section may attenuate components of the third specific frequency or lower in the effect sounds (the effect sounds of channels CH1 and CH2) output from the lower speakers 100a and 100b. In other words, the frequency response of the fifth equalizer section may be set so that the gain is less than 0 dB in a band below the third specific frequency. Here, the third specific frequency may be set to, for example, 100 Hz, and at least part of the low frequency range (for example, the range of 20 Hz to 100 Hz) of the effect sound output from the lower speakers 100a and 100b may be attenuated. In other words, the third specific frequency may be set to a higher frequency than the lowest resonance frequency of 90 Hz of the lower speakers 100a, 100b. Further, the third specific frequency may be set to a frequency lower than the lowest resonance frequency of 235 Hz of the upper speakers 100c and 100d. Further, the third specific frequency may be set to a lower frequency than the test tone. More specifically, the third specific frequency is preferably set to a lower frequency than at least one of the test tones that the slot machine X can output, and all the test tones that the slot machine X can output. It may be set to a lower frequency. In other words, it is preferable that at least one test tone with a frequency higher than the third specific frequency is prepared (stored in the storage means 78 or can be generated by a signal generator), and it is preferable that a plurality of test tones are prepared. It is further preferable that the By preparing at least one test tone with a frequency higher than the third specific frequency, it is possible to perform an inspection with components of frequencies lower than the third specific frequency cut. According to such a configuration, unnecessary band components can be eliminated from the sound output from the lower speakers 100a, 100b, the load on the lower speakers 100a, 100b can be reduced, and the amount of heat generated can be reduced. . Further, the load on the lower speakers 100a and 100b due to the component of the lowest resonant frequency can be reduced.
Note that the processing in the fifth equalizer section may be performed in the third equalizer section. In other words, the predetermined frequency for the lower speakers 100a, 100b in the third equalizer section may be set to the third specific frequency.

Moreover, the effect sound control section 76 may be configured by a plurality of ICs. However, if it is possible to change the effect sound mode based on the player's operation, it is preferable that the second equalizer section 155b is provided in the effect control IC 76. When the second equalizer section 155b is provided in the amplifier IC, for example, the settings of the second equalizer section 155b will be changed by I2C communication etc. from the production control IC, and the output of the production sound will be temporarily stopped when changing the mode. However, by providing the second equalizer section 155b in the performance control IC, it becomes possible to change the mode while continuing to output the performance sound. On the other hand, for equalizer sections whose settings are not changed based on player operations or equalizer sections whose settings are not changed during the game (for example, the third to fifth equalizer sections), the amplifier IC may be provided. Furthermore, in the gaming machine of this embodiment, the effect sound decoded by the decoder section 150 is processed by the first equalizer section 155a, and then processed by the second equalizer section 155b to the fifth equalizer section.

For example, the normal mode setting information and the treble cut mode setting information of the second equalizer section 155b are stored in the equalizer setting storage section of the storage section 78, and the effect sound control section 76 controls the operation of the effect operation section 57. The configuration information to be used is determined based on the configuration information, and the register settings are rewritten according to the determined configuration information.
