Further, the two upper speakers 100c and 100d are arranged so as to be separated from each other on the left and right, and are arranged at substantially the same position (height) from each other in the vertical direction. In addition, in this specification, substantially the same (substantially the same) includes the case of the same (the same). That is, the gaming machine of the present embodiment has a speaker 100a whose relative position between the four speakers is the lower left, a speaker 100b which is the lower right, a speaker 100c which is the upper left, and a speaker 100d which is the upper right. It has one speaker. 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.

Further, the gaming machine of the present 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 arranged apart from each other on the left and right, and are arranged at substantially the same position (height) from 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 having different specifications (speakers having different model numbers). In other words, the reproducible frequency band (reproduction frequency band (rated frequency band): frequency characteristic) is different between the lower speakers 100a and 100b, the upper speakers 100c and 100d, and the tweeters 100e and 100f. 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 a larger diaphragm area (diameter) than the upper speakers 100c and 100d. Specifically, the diaphragms of the lower speakers 100a and 100b have a circular shape and a diameter of about 10 cm. The diaphragms of the upper speakers 100c and 100d have an oval shape, and the major axis is about 10 cm and the minor axis is about 4.5 cm. Therefore, the lower speakers 100a and 100b can be said to be large speakers. Further, the upper speakers 100c and 100d can be said to be small speakers. Further, the tweeters 100e and 100f have a smaller diaphragm area (caliber) than the upper speakers 100c and 100d. Specifically, the diaphragms of the tweeters 100e and 100f have a circular shape and 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 90 Hz to 16 kHz. The minimum resonance frequency of the lower speakers 100a and 100b is 90 Hz. The reproduction frequency band of the upper speakers 100c and 100d is 235 Hz to 18 kHz. The minimum resonance frequency of the upper speakers 100c and 100d is 235 Hz. The reproduction frequency band of the tweeters 100e and 100f is 2 kHz to 20 kHz. The minimum resonance frequency of the tweeters 100e and 100f is 2 kHz. The lower speakers 100a and 100b and the upper speakers 100c and 100d can output sound in a wider range than other speakers such as tweeters and woofers (the reproduction frequency band is wide), and can be said to be a full-range speaker.

Further, the lower speakers 100a and 100b and the upper speakers 100c and 100d commonly include a band of 235 Hz to 16 kHz (frequency band A) in the reproduction frequency band. Further, the lower speakers 100a and 100b, the upper speakers 100c and 100d and the tweeters 100e and 100f commonly include a band of 2 kHz to 16 kHz (frequency band B) in the reproduction frequency band. Further, the upper speakers 100c and 100d and the tweeters 100e and 100f commonly include a band of 2 kHz to 18 kHz (frequency band C) in the reproduction frequency band. Further, the lower speakers 100a and 100b and the tweeters 100e and 100f commonly include a band of 2 kHz to 16 kHz (frequency band D) in the reproduction frequency band. Further, the bandwidth (frequency range) of the frequency band C is wider than that of the frequency band A, and the frequency band A is wider than that of the frequency band B.

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

As shown in FIG. 4, the effect sound control unit 76 includes a decoder unit 150, a first volume control unit 151, a second volume control unit 153, an equalizer unit (frequency characteristic control unit) 155, and a third volume control. It has a unit 157 and an audio output unit 159. Further, the effect sound control unit 76 has a plurality of tracks (for example, a total of 40 tracks 1 to 40) and a plurality of tracks (for example, a total of 8 channels CH1 to CH8 (CH7 and CH8 are not shown)). It has a channel of. Here, the track is an execution unit for reproducing each production sound (phrase data) stored in the production sound storage unit (ROM) 160 of the storage unit 78, and the channel is the production sound data of the production sound control unit 76. It is an output unit. The effect sound control unit 76 synthesizes and outputs the effect sound (output of each track) reproduced on each track in each channel.
The production sound storage unit 160 stores, for example, a series of background music (BGM), warning sounds, sound effects, and production sounds such as character dialogue sounds.

In the following, the volume setting values will be set to 256 levels from "0" to "255", the volume "0" will be described as silence, and the volume "255" will be described as the maximum volume, but each setting value and the number of levels are particularly limited. It's not something to do.

The decoder unit 150 can independently perform decoding processing for each track. As a result, the effect sound control unit 76 can simultaneously reproduce up to 40 effect sounds (effect sounds read from the effect sound storage unit 160). The effect sound of each track decoded by the decoder unit 150 is input to the first volume control unit 151.

The first volume control unit 151 can adjust the volume for each track. Further, the first volume control unit 151 can adjust the volume of each track for each output destination channel. That is, for example, when the BGM is reproduced on the track 1 and the dialogue sound of the character is reproduced on the track 2, the volume of the BGM reproduced on the track 1 is set to "100", and the dialogue of the character reproduced on the track 2 is set. It is possible to make the volume setting different for each track, such as setting the volume of the sound to "150". Further, for example, the BGM played on the track 1 is output as the volume "100" for the channel CH1 and the volume is output as the volume "50" for the channel CH2, and the volume setting is set for each output destination channel. It is possible to make them different.

The reproduced sound in each track is output to each channel at a volume corresponding to the setting of the first volume control unit 151, and is combined (superimposed) in each channel. That is, in each channel, a production sound (synthesized production sound) obtained by synthesizing the production sound of each track is handled. Then, the effect sound (synthesized effect sound) of each channel in which the output of the first volume control unit 151 is combined is input to the second volume control unit 153.

The second volume control unit 153 can adjust the volume for each channel. Then, the combined production sound of each channel whose volume is adjusted by the second volume control unit 153 is input to the equalizer unit 155.

The equalizer unit 155 can realize a desired frequency characteristic for each channel. Specifically, the equalizer unit 155 can strengthen or weaken a predetermined frequency band of the synthetic effect sound according to the setting. In other words, the equalizer unit 155 can increase or decrease the volume (sound pressure level) of the synthetic production sound for each frequency band. In other words, the equalizer unit 155 can set how much the input / output gain should be for each frequency band of the synthetic production sound. Further, it can be said that the equalizer unit 155 functions as a filter circuit (digital filter). That is, the first volume control unit 151, the second volume control unit 153, and the third volume control unit 157 perform the entire frequency band (at least the audible band or the reproduction frequency band of the corresponding speaker 100) for the production sound of each track or each channel. While the volume (gain) of the entire) is uniformly increased or decreased, the equalizer unit 155 may increase or decrease the volume (gain) of a predetermined band included in the audible band (reproduction frequency band of the speaker 100). It is possible.

The synthetic production sound of each channel that has passed through the equalizer unit 155 is input to the third volume control unit 157. The third volume control unit 157 can uniformly adjust the volume for all channels. That is, the volume of all channels is uniformly increased or decreased according to the setting of the third volume control unit 157.

The audio output unit 159 is configured to be capable of outputting, for example, a bit clock signal BCLK, a word clock signal LRCLK, and a serial data signal SDATA conforming to the I2S (Inter-IC Sound) standard. The audio output unit 159 outputs the combined production sound of each channel output from the third volume control unit 157 in a method conforming to the I2S standard. In the gaming machine of the present embodiment, it is possible to output a plurality of serial data signals SDATA including the first serial data signal SDATA1, the second serial data signal SDATA2, and the third serial data signal SDATA3. The first serial data signal SDATA1 includes data of the combined production sound of channel CH1 and channel CH2, and the second serial data signal SDATA2 contains data of the combined production sound of channel CH3 and channel CH4. The third serial data signal SDATA3 includes data of synthetic production sounds of channel CH5 and channel CH6.

The bit clock signal BCLK, the word clock signal LRCLK, and the serial data signal SDATA output from the audio output unit 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 sent 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 based on the first serial data signal SDATA1 sent from the effect sound control unit 76 to output sound. The word clock signal LRCLK and the first serial data signal SDATA1 are synchronized, and when the word clock signal LRCLK is at the Low level, the first serial data signal SDATA1 including the data of the synthetic effect sound of the channel CH1 is transmitted. When the word clock signal LRCLK is at the High level, the first serial data signal SDATA1 including the data of the synthetic effect sound of the channel CH2 is transmitted. The amplifier 113 causes the speaker 100a to output a production sound based on the first serial data signal SDATA1 input when the word clock signal LRCLK is at the Low level. Further, the amplifier 113 causes the speaker 100b to output an effect sound based on the first serial data signal SDATA1 input when the word clock signal LRCLK is at the High level. Therefore, the composite production sound of the channel CH1 is output from the speaker 100a, and the composite production sound of the channel CH2 is output from the speaker 100b.

The amplifier 114 drives the speaker 100c and the speaker 100d based on the second serial data signal SDATA2 sent from the effect sound control unit 76 to output sound. The word clock signal LRCLK and the second serial data signal SDATA2 are synchronized, and when the word clock signal LRCLK is at the Low level, the second serial data signal SDATA2 including the data of the synthetic effect sound of the channel CH3 is transmitted. When the word clock signal LRCLK is at the High level, the second serial data signal SDATA2 including the data of the synthetic effect sound of the channel CH4 is transmitted. The amplifier 114 causes the speaker 100c to output a production sound based on the second serial data signal SDATA2 input when the word clock signal LRCLK is at the Low level. Further, the amplifier 114 causes the speaker 100d to output an effect sound based on the second serial data signal SDATA2 input when the word clock signal LRCLK is at the High level. Therefore, the composite production sound of the channel CH3 is output from the speaker 100c, and the composite production sound of the channel CH4 is output from the speaker 100d.

The amplifier 115 drives the speaker 100e and the speaker 100f based on the third serial data signal SDATA3 sent from the effect sound control unit 76 to output sound. The word clock signal LRCLK and the third serial data signal SDATA3 are synchronized, and when the word clock signal LRCLK is at the Low level, the third serial data signal SDATA3 including the data of the synthetic effect sound of the channel CH5 is transmitted. When the word clock signal LRCLK is at the High level, the third serial data signal SDATA3 including the data of the synthetic effect sound of the channel CH6 is transmitted. The amplifier 115 causes the speaker 100e to output a production sound based on the third serial data signal SDATA3 input when the word clock signal LRCLK is at the Low level. Further, the amplifier 115 causes the speaker 100f to output an effect sound based on the third serial data signal SDATA3 input when the word clock signal LRCLK is at the High level. Therefore, the composite production sound of the channel CH5 is output from the speaker 100e, and the composite production sound of the channel CH6 is output from the speaker 100f.

In the gaming machine of the present embodiment, the equalizer unit 155 has a first equalizer unit 155a and a second equalizer unit 155b. The first equalizer unit 155a and the second equalizer unit 155b are adapted to change the frequency characteristics of the effect sound according to the frequency characteristics (frequency response) set respectively. In other words, the first equalizer unit 155a and the second equalizer unit 155b are digital filters having frequency characteristics (frequency response) according to the settings, respectively.

The first equalizer unit 155a has a frequency characteristic (volume) of the sound input to the decoder unit 150 and output from the speaker 100 so that the gain (volume) is substantially constant over substantially the entire reproduction frequency band of each speaker 100. Frequency response) is set. That is, the sound input to the decoder unit 150 and output from the speaker 100 is usually reproduced due to the frequency characteristics of the speaker 100, the influence of the circuit driving the speaker 100, the shape of the portion (enclosure) accommodating the speaker 100, and the like. A predetermined frequency component in the frequency band will be attenuated. The first equalizer unit 155a performs a process of correcting a change in the frequency characteristic of the effect sound due to these factors. Specifically, the first equalizer unit 155a has a gain characteristic of input to output substantially uniform (flat) over substantially the entire reproduction frequency band of each speaker for the sound input to the decoder unit 150 and output from each speaker 100. Perform a process (uniformization process) so as to be.

The setting of the first equalizer unit 155a that enables such homogenization processing is, for example, to input white noise to the decoder unit 150 and output it from the speaker 100, and then output the sound of the speaker 100 with a microphone. The sound is collected, and the setting (frequency response) of the first equalizer unit 155a is adjusted so that the frequency characteristic of the collected output sound becomes flat (so that the volume of the output sound becomes uniform in a predetermined frequency range). It can be realized by. Specifically, for example, the frequency characteristics of the output sound when white noise is input to the decoder unit 150 and output from the speaker 100 without correction in the first equalizer unit 155a are shown in FIGS. 5 (a) and 5 (b). ), The first equalizer unit 155a is set so that the frequency characteristics of the output sound are shown by the broken lines in FIGS. 5A and 5B. Note that FIG. 5A shows the frequency characteristics of the output sound in the normal mode described later, and FIG. 5B shows the frequency characteristics of the output sound in the treble cut mode described later.

The setting of the first equalizer unit 155a can be adjusted for each speaker (for each channel). In the gaming machine of the present 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 supposed to be set. The setting of the first equalizer unit 155a for each channel is adjusted so that the gain characteristics from the input of the decoder unit 150 to the output of the speaker 100 are substantially uniform over the entire reproduction frequency band of the corresponding speaker 100. Alternatively, the gain characteristic may be adjusted to be substantially uniform for a predetermined frequency range in which the gain characteristic is desired to be substantially uniform for the corresponding speaker 100.

Further, the effect sound control unit 76 can change the setting of the second equalizer unit 155b based on the user's operation on the effect operation unit 57. In the gaming machine of the present embodiment, the high-pitched sound cut mode that suppresses (attenuates) the component of the predetermined frequency or higher and the component of the predetermined frequency or higher is not suppressed (attenuated) with respect to the effect sound output from the predetermined speaker 100. ) Multiple (at least two) modes (directing sound mode) including the normal mode are prepared. That is, in the treble cut mode, the amount of attenuation of the component having a predetermined frequency or higher of the effect sound is larger than that in the normal mode. Then, the effect sound control unit 76 changes the setting of the second equalizer unit 155b according to the mode so that the second equalizer unit 155b has a desired frequency characteristic (frequency response) according to the mode. There is.

The 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, the liquid crystal display 34 may display a screen for selecting a mode related to the effect sound based on the operation of the player, and the mode may be selected by operating the cross key or the enter button of the effect operation unit 57. ..

The frequency characteristics (input vs. output gain characteristics) of the second equalizer unit 155b in the normal mode are shown in FIG. 6A. Further, FIG. 6B shows the frequency characteristics (input vs. output gain characteristics) of the second equalizer unit 155b in the treble cut mode. As shown in FIG. 6A, in the normal mode, the frequency characteristic of the second equalizer unit 155b is flat in all bands. In other words, in the normal mode, the gain of the second equalizer unit 155b is 0 dB in the entire reproduction frequency band of the speakers 100a, 100b, 100c, 100d, 100e, 100f. In other words, in the normal mode, the gain of the second equalizer unit 155b is 0 dB in the band of 200 Hz or more and 20 kHz or less. That is, in the normal mode, the second equalizer unit 155b does not change the frequency characteristic of the passing effect sound and allows it to pass through as it is.

Further, as shown in FIG. 6B, in the treble cut mode, the gain of the second equalizer unit 155b is less than 0 dB in the band of a specific frequency (for example, 3 kHz) or higher. Further, in the band below the specific frequency, the gain is 0 dB. That is, in the treble cut mode, the second equalizer unit 155b attenuates the components of the passing effect sound having a specific frequency or higher. In other words, in the treble cut mode, the second equalizer unit 155b performs low-pass filter processing on the effect sound to allow components below a specific frequency to pass through without being attenuated, while attenuating (cutting) components above a specific frequency. ).

Here, the specific frequency in the second equalizer unit 155b is preferably set to 3 kHz or higher. Further, the specific frequency is preferably set to 10 kHz or less, more preferably 8 kHz or less, and further preferably 6 kHz or less. By setting a specific frequency in this way, it is possible to remove sounds that are irritating to the ear. In the example shown in FIG. 6B, the specific frequency is set to 3 kHz, and the cutoff frequency is set to about 6 kHz.

Further, the specific frequency is set to a frequency higher than the test tone. Here, the test tone is a single-frequency sine wave sound (sine wave signal), and is a signal for inspecting the sound output. The gaming machine of the present embodiment can output a plurality of types of test tones, and for example, a test tone of 500 Hz and a test tone of 1 kHz are prepared. Specifically, the data of the test tone of 500 Hz is stored in the storage unit 78, and the effect sound control unit 76 can output the test tone of 500 Hz from each speaker 100 based on the data. ing. Further, the effect sound control unit 76 has a signal generator (oscillator), and is capable of generating a test tone of 1 kHz. Then, the 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 frequency higher than at least one of the test tones that the slot machine X can output, and is set to a frequency higher than all the test tones that the slot machine X can output. May be good. In other words, it is preferable that at least one test tone having a frequency lower than a 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 prepared. It is more preferable to have. By preparing at least one test tone having a frequency lower than a specific frequency, it is possible to perform an inspection in the treble cut mode.

Further, in the treble cut mode, the second equalizer unit 155b is a component of the effect sound output from the speaker 100 having a specific frequency or higher for at least one of the speakers 100 whose frequency equal to or higher than the specific frequency is included in the reproduction frequency band. Is designed to be attenuated. In the gaming machine of the present embodiment, in the treble cut mode, the second equalizer unit 155b is equal to or higher than the specific frequency of the effect sound output from the speaker 100 for all the speakers 100 whose frequency above the specific frequency is included in the reproduction frequency band. 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 setting of the second equalizer unit 155b is changed for the predetermined speaker (predetermined channel). When the mode is changed between the normal mode and the treble cut mode, the setting of the second equalizer section 155b may be changed for all channels, and the setting of the second equalizer section 155b may be changed for some channels. The setting may not be changed, or the setting may be different for each channel (specific frequency may be different).
The gaming machine may include a woofer (speaker 100) that is in charge of outputting low-pitched sound from the lower speakers 100a and 100b. Here, the woofer is, for example, a speaker having a lower lower limit value and an upper limit value of the frequency of the reproduction frequency band than 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 a frequency of a specific frequency or higher (if the upper limit is higher than the specific frequency), the effect sound output from the woofer is also a component of the specific frequency or higher. May be attenuated.

The equalizer unit 155 may have a third equalizer unit, and the third equalizer unit may attenuate (cut) a component of a predetermined frequency or less of the effect sound. In other words, the equalizer unit 155 may have a third equalizer unit that performs a high-pass filter process that attenuates (cuts) components below a predetermined frequency. Specifically, the third equalizer unit may execute a process of attenuating the components of 90 Hz or less (or, for example, 100 Hz or less) with respect to the effect sound output from the lower speakers 100a and 100b, from the upper speakers 100c and 100d. A process of attenuating the component of 235 Hz or less (or, for example, 240 Hz or less) may be executed for the effect sound to be output, and the component of 2 kHz or less (or, for example, 2020 Hz or less) is attenuated for the effect sound output from the tweeters 100e, 100f. You may execute the process to make it. In other words, the third equalizer unit may execute a process of attenuating a component below the minimum resonance frequency of 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 resonance frequency can be reduced.

Further, the equalizer unit 155 has a fourth equalizer unit, and the fourth equalizer unit attenuates (cuts) a component of the effect sound output from the speaker 100 below the second specific frequency with respect to the predetermined speaker 100. It may be. For example, the fourth equalizer unit may attenuate the components of the second specific frequency or lower with respect to the effect sounds (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 unit may be set so that the gain is less than 0 dB in the band below the second specific frequency. Here, the second specific frequency may be set to, for example, 800 Hz, and at least a part of the midrange (for example, the range of 100 Hz to 1 kHz) 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 frequency higher than the minimum resonance frequency of 235 Hz of the upper speakers 100c and 100d. Further, the second specific frequency may be set to a frequency higher than the minimum resonance frequency of 90 Hz of the lower speakers 100a and 100b. Further, the second specific frequency may be set to a frequency lower than the test tone. More specifically, the second specific frequency is preferably set to a frequency lower 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 having 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 a plurality of test tones are prepared. It is more preferable that it is. By preparing at least one test tone having a frequency higher than the second specific frequency, it is possible to perform an inspection in a state where components having a frequency lower than the second specific frequency are cut. According to such a configuration, with respect to the production sound output from the upper speakers 100c and 100d, which are in charge of outputting the sound in the relatively high range, the component in the midrange is reduced and the sound in the relatively low range is in charge of the output. It is possible to prevent the production sound and the band output from the lower speakers 100a and 100b from being covered. 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. Further, by eliminating unnecessary band covering, the load on each speaker 100 can be reduced and the amount of heat generated can be reduced. Further, the load on the upper speakers 100c and 100d due to the component of the lowest resonance frequency can be reduced.
The processing in the 4th equalizer section may be performed in the 3rd equalizer section. In other words, the predetermined frequency of the upper speakers 100c and 100d in the third equalizer unit may be set to the second specific frequency.

Further, the equalizer unit 155 has a fifth equalizer unit, and the fifth equalizer unit attenuates (cuts) a component of the effect sound output from the speaker 100 below the third specific frequency with respect to the predetermined speaker 100. It may be. For example, the fifth equalizer unit may attenuate the components of the third specific frequency or lower with respect to the effect sounds (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 unit may be set so that the gain is less than 0 dB in the band below the third specific frequency. Here, the third specific frequency may be set to, for example, 100 Hz, and at least a part of the low frequency range (for example, the sound range of 20 Hz to 100 Hz) may be attenuated with respect to the effect sound output from the lower speakers 100a and 100b. In other words, the third specific frequency may be set to a frequency higher than the minimum resonance frequency of 90 Hz of the lower speakers 100a and 100b. Further, the third specific frequency may be set to a frequency lower than the minimum resonance frequency of 235 Hz of the upper speakers 100c and 100d. Further, the third specific frequency may be set to a frequency lower than the test tone. More specifically, the third specific frequency is preferably set to a frequency lower 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 having 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 a plurality of test tones are prepared. It is more preferable that it is. By preparing at least one test tone having a frequency higher than the third specific frequency, it is possible to perform an inspection in a state where components having a frequency lower than the third specific frequency are cut. According to such a configuration, it is possible to eliminate components in an unnecessary band for the sound output from the lower speakers 100a and 100b, reduce the load on the lower speakers 100a and 100b, and reduce the amount of heat generated. .. Further, the load on the lower speakers 100a and 100b due to the component of the lowest resonance frequency can be reduced.
The processing in the 5th equalizer section may be performed in the 3rd equalizer section. In other words, the predetermined frequency of the lower speakers 100a and 100b in the third equalizer unit may be set to the third specific frequency.

It may have a function (first volume control unit 151, second volume control unit 153, third volume control unit 157, etc.). Specifically, for example, the amplifier IC (amplifier 113, 114, 115) may be provided with the second equalizer unit 155b, and the amplifier IC (amplifier 113, 114, 115) may execute the above-mentioned low-pass filter processing. good.

However, when it is possible to change the effect sound mode based on the operation by the player, it is preferable that the second equalizer unit 155b is provided in the effect control IC76. When the second equalizer unit 155b is provided in the amplifier IC, for example, the setting of the second equalizer unit 155b is changed from the effect control IC by I2C communication or the like, and the output of the effect sound is temporarily stopped when the mode is changed. By providing the second equalizer unit 155b in the effect control IC, it is possible to change the mode while continuing to output the effect sound. On the other hand, the amplifier IC is used for the equalizer section whose settings are not changed based on the player's operation and the equalizer section (for example, the third to fifth equalizer sections) whose settings are not changed during the game. It may be provided in. Further, in the gaming machine of the present embodiment, the effect sound decoded by the decoder unit 150 is processed by the first equalizer unit 155a, and then processed by the second equalizer units 155b to the fifth equalizer unit.

For example, the normal mode setting information and the treble cut mode setting information of the second equalizer unit 155b are stored in the equalizer setting storage unit of the storage unit 78, and the effect sound control unit 76 operates the effect operation unit 57. The setting information to be used is determined based on the above, and the register settings are rewritten according to the determined setting information. Further, the effect sound control unit 76 determines the effect sound to be output from each speaker 100 according to the effect determined by the effect control unit 74 based on the command from the main control board 70, and controls the output of the effect sound. It has become. The setting of the third volume control unit 157 may be determined according to the state of the volume change switch (not shown) provided on the sub-control board 72.
