In this embodiment, as shown in FIG. 2, the symbol display units are accommodated and set in parallel in the middle frame 12.
[0017]
In addition, an upper ball dish 16 and a lower ball dish 17 that store pachinko balls are disposed below the visible display portion 13a in the front frame 13, respectively. There are provided a ball take-in button 18a for taking a ball into the machine, a start lever 18b for starting the symbol combination game by rotating the symbol belts 15a in the same direction. Further, stop buttons 18c corresponding to the respective symbol belts 15a are respectively provided on the front side of the upper ball tray 16, and the corresponding symbol belts 15a are stopped by pressing the stop buttons 18c. It has become. Then, according to the result of the symbol combination game (combination of symbols stopped on the visible display portion 13a), the game state shifts to a game state advantageous to the player, and a prize ball not shown in the upper ball tray 16 or the lower ball tray 17 is displayed. A predetermined number of pachinko balls are dispensed under the operation of the dispensing device.
[0018]
At the upper position of the front frame 13, there is provided a decorative portion 19 with a required decoration. Below the decorative portion 19, a front plate 22 a of the enclosure 21 in which a space portion 21 a is defined is provided. It is arranged in a state of tilting backward as it goes downward (see FIG. 1 or FIG. 2). As shown in FIG. 3, the enclosure 21 is formed of a substantially rectangular box-shaped case body 22 opened on the rear side, and a shielding plate 25 covering the entire rear opening of the case body 22. Boss portions 22b and 22b each having a screw hole (not shown) at the rear end project from the rear end of the front plate 22a of the case body 22 at a position separated by a required distance in the left-right direction. Through holes (not shown) are formed in the shielding plate 25 at positions aligned with the respective boss portions 22b in the front-rear direction, and screws (not shown) inserted from the rear of the through holes are screwed into the screw holes. By inserting, both members 22 and 25 are fixed. A joint material (not shown) such as rubber packing is interposed between the case body 22 and the shielding plate 25 so as to ensure the airtightness of the enclosure 21.
[0019]
In the vicinity of both side portions of the front plate 22a of the case body 22, mounting holes (first openings) 23a, 23a communicating the space portion 21a with the outside are provided on the front side of the pachinko slot machine 10 ( Projecting portions 22c and 22c projecting rearward are formed in the vicinity of each mounting hole 23a. In each mounting hole 23a, a speaker (sound effect output device) 26 faces from the rear side of the mounting hole 23a, and the front surface of each speaker 26 is exposed to the outside. Here, each speaker 26 has a front end edge of the speaker 26 attached to the front plate 22a of the case body 22 by screwing and fixing the attachment portion 26a fixed to the speaker 26 to the projecting portions 22c and 22c. It comes in close contact (see FIG. 4). As shown in FIG. 1, a cover member 27 is disposed on the front side of the speaker 26 to prevent damage to each speaker 26. In addition, each of the speakers 26 is sounded at an audible frequency (frequency is approximately 20 Hz to 20,000 Hz) by a sound control device (not shown) disposed on the back side of the pachinko slot machine 10 (inner frame 12). Alternatively, a sound wave having an inaudible frequency (a frequency other than the audible frequency) is controlled to be selectively emitted according to the symbol combination game on the symbol display device 15.
[0020]
As shown in FIG. 3, at a substantially central position that is separated from the mounting holes 23a, 23a formed on the front plate 22a of the case body 22 by a required distance, a first blower opening (vertically long rectangular shape) ( Second opening) 23b is formed. In addition, a bass reflex duct 24 having a required length extending to the space portion 21a in the enclosure 21 is formed on the outer peripheral edge of the first air blowing port 23b, and the first air blowing port 23b and the bass reflex duct 24 are interposed therebetween. The space 21a communicates with the outside. That is, the sound wave emitted from the front side of each speaker 26 is directly transmitted to the outside through the mounting hole 23a, and the sound wave emitted from the rear side of the speaker 26 is transmitted to the space portion 21a and the bass reflex duct. 24 is transmitted to the outside from the first air blowing port 23b. A cover member 28 is attached to the first air outlet 23b (see FIG. 1) to prevent foreign matter from entering the enclosure 21.
[0021]
[Operation of the first embodiment]
Next, the operation of the pachinko slot machine according to the first embodiment will be described.
[0022]
When the player operates the ball take-in button 18a to take in a predetermined number of pachinko balls and then operates the start lever 18b, the symbol belt 15a of the symbol display device 15 is rotated to start a symbol combination game. Is done. At this time, a sound wave of an audible frequency is emitted from the speaker 26 based on the control of the sound control device, increasing the interest of the game. By the way, in general, before and after the speaker, for example, when the cone of the speaker moves forward, the air on the front side is pushed and becomes “dense” while the rear side becomes “sparse” with a thin air. The reverse action is performed before and after the speaker as a boundary. That is, since sound waves with opposite phases are output from the front and rear of the speaker, it is known that when the sound waves with opposite phases output from the front and rear of the speakers interfere with each other, the sounds cancel each other and the sound becomes unclear. (Especially the effect on the low frequency range)
[0023]
In the first embodiment, the case body 22 and the shielding plate 25 cover the rear side of the speaker 26, so that the interference of the sound output from the front and rear of the speaker 26 is effectively prevented and a clear " You can enjoy games with sound. If the volume of the space 21a of the enclosure 21 is changed, it is possible to change the limit (limit frequency) of the low frequency range that can be output clearly (in general, the limit frequency is lowered by increasing the volume). , Will be able to output a "sound" in the lower range). Further, since a joint material is provided between the case body 22 and the shielding plate 25 to ensure the airtightness of the space portion 21a, sound leakage of sound waves output from the rear surface side of the speaker 26 is achieved. Can prevent.
[0024]
Furthermore, generally speaking, when a sound is emitted from a speaker by forming an opening that communicates the space in the enclosure with the outside and a bass reflex duct that extends from the opening into the enclosure, the sound emitted from the rear side of the speaker is In addition, a so-called Hertzholm resonance occurs between the space and the bass reflex duct, and a sound is emitted from the opening by resonating at a specific frequency (referred to as an anti-resonance frequency). At higher frequencies, it is known to be in phase with the sound emitted from the front of the speaker. That is, in the pachinko slot machine 10 of the first embodiment, a speaker 26 is disposed in the enclosure 21 provided with the first air outlet 23b and the bass reflex duct 24 that communicate the space 21a with the outside. As a result, the sound wave emitted from the front side of the speaker 26 and the sound wave emitted from the first air outlet 23b are in phase and strengthen each other, further enhancing the power and the presence. "Sound" can be enjoyed.
[0025]
Furthermore, since the sound wave emitted from the speaker 26 is a dense wave due to air vibration, when the sound wave emitted to the space 21a is in a “dense” state, the internal pressure of the space 21a is It becomes temporarily high. For this reason, the air in the space 21 a is pushed out from the first air outlet 23 b through the bass reflex duct 24. On the other hand, when the sound wave emitted to the space portion 21a is in a “sparse” state, the internal pressure of the space portion 21a is temporarily low, so that the external air flows from the first air outlet 23b. Is pulled back into the enclosure 21.
[0026]
Thus, when the speaker 26 is operated, the air in the space 21a is vibrated by the sound wave emitted from the rear surface side of the speaker 26 to the space 21a, and the pressure in the space 21a changes. As a result, the internal air is sent out from the first air outlet 23b. That is, since the “wind” is blown out toward the player through the bass reflex duct 24 and the first air blowing port 23b, it is possible to further increase the interest of the game by playing the game with the “wind”. . Further, since the first air blowing port 23b is formed above the symbol display device 15, the "wind" from the first air blowing port 23b is blown out toward the player's face and the "wind" The production effect by is further enhanced.
[0027]
Further, if the frequency and sound pressure of sound waves emitted from the speaker 26 are controlled by the sound control device, it is possible to change the strength of the “wind” that is perceived by the player. In this way, by forming the first air outlet 23b in the enclosure 21 in which the speaker 26 is disposed, it is possible to increase the interest of the game by blowing air to the player from the first air outlet 23b. It is possible to reduce the cost and work burden of newly installing a blower fan and control means for the fan. Since the sound control device controls the speaker 26 to selectively emit sound waves having an audible frequency or sound waves having an inaudible frequency, if only sound waves having an inaudible frequency are emitted from the speaker 26, the game Since the player can recognize the “wind” effect without recognizing the “sound”, the game effect can be achieved in various modes, and the interest of the game is further increased.
[0028]
[Second embodiment]
In the second embodiment, a pachinko machine is adopted as a gaming machine that shifts to a gaming state advantageous to the player according to the result of the symbol combination game, and the cone type speaker is disposed in the pachinko machine. To do. The same members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. As shown in FIG. 5, the pachinko machine 30 is assembled such that the middle frame 32 can be attached to and detached from the front side of the opening of the outer frame 31 by using a connection support means 45 and a locking means 46, A front frame 33 in which a glass frame 34 and an upper ball tray 35 are assembled is attached to the middle frame 32. Further, a lower ball tray 36, a hit ball launching device (hit ball launching means) 37, and the like are installed below the middle frame 32. By operating the hitting ball launching device 37, pachinko balls (not shown) stored in the upper ball tray 35 are shot one by one into a game area 38a described later.
[0029]
The game board 38 that is set to the middle frame 32 so as to be attachable / detachable is defined with a game area 38a surrounded by a rail (not shown) that is curved in a substantially circular shape, on the front side of the game area 38a. A symbol display device (symbol display portion) 40 for playing a symbol combination game faces a visible display portion 39a of a decorative member 39 that is arranged at a substantially central position and decorates the game board 38. In the game area 38a, a pachinko ball is inserted to start a symbol combination game, a starting prize is decorated to decorate the game board 38, and a game is opened according to the result of the symbol combination game. A winning device for shifting to a gaming state advantageous to the player and a number of other gaming parts (none of which are shown) are provided.
[0030]
Further, the lower position of the outer frame 31 includes a case body that opens rearward and a shielding plate (none of which is shown) that closes the rear opening of the case body, as in the first embodiment. A configured enclosure 41 is disposed. An attachment hole (not shown) for attaching the speakers 26, 26 is formed at a position separated from the left and right of the case body, and each speaker 26 is arranged to face the front side of the pachinko machine 30. Each speaker 26 is controlled by an audio control device (control means) (not shown) arranged on the back side of the pachinko machine 30 according to a symbol combination game on the symbol display device 40, or an audible sound wave or an inaudible frequency. The sound wave is controlled to be emitted selectively.
[0031]
As shown in FIG. 5, the enclosure 41 extends to the vicinity of the ball hitting device 37, and a second air outlet (second opening) that communicates the space 41 a in the enclosure 41 with the outside. ) 42 is opened toward the ball hitting device 37, and the passage extending from the right end portion of the enclosure 41 to the second air blowing port 42 is configured to function as the second bass reflex duct 44. Yes. That is, the second blower opening 42 is opened toward the player's hand holding the hitting ball launching device 37. Note that a cover member 43 that prevents foreign matter from entering the inside of the enclosure 41 is attached to the second blower opening 42.
[0032]
[Operation of the second embodiment]
Next, the operation of the pachinko machine according to the second embodiment will be described.
[0033]
When the player operates the hitting ball launching device 37 to hit the pachinko ball of the upper ball tray 35 into the game area 38a, and when the hit pachinko ball enters the start winning tool, the symbol display device 40 is used. Then, the symbols are changed and the symbol combination game is started. At this time, from the speakers 26, 26, a sound wave having an audible frequency or a sound wave having an inaudible frequency is selectively emitted based on the control of the sound control means. Therefore, also in this case, the same effect as the first embodiment described above can be obtained. Further, in the second embodiment, the second air blowing port 42 through which “wind” is sent out is formed in the vicinity of the ball hitting device 37 held by the player when playing the game. Since air from the air vent 42 can be sensitively recognized, an effective presentation by “wind” can be performed.
[0034]
[Example of change]
In each embodiment, a pachinko slot machine or a pachinko machine has been described as an example of a gaming machine. However, the present invention is not limited to this, and an arrangement ball machine, a slot machine, or the like may be used. The sound effect output device disposed in the enclosure is not limited to a speaker, and conventionally known devices and members that can output various “sounds” can be employed. Furthermore, although the sound effect output devices are arranged one by one in the space defined by the case body and the shielding plate, the number and arrangement position are not limited thereto. It can be changed as appropriate.
[0035]
Further, although the speakers are arranged in the same enclosure, they may be arranged in independent enclosures. For example, as shown in FIG. 6, a partition plate 58 is provided at a required position of the case body 57, and the first enclosure 51 and the second enclosure 52 are separated from each other on the left and right sides. The first enclosure 51 includes a third air outlet (second opening) 51b that connects the first space 51a defined inside the first enclosure 51 and the outside, and a bass reflex. Whereas the duct 51c is formed, the second enclosure 52 is configured such that the second space 52a defined inside the second enclosure 52 and the outside are not in communication. Further, a first speaker 55 that emits a sound wave of an inaudible frequency is directed to the front side from a first mounting hole (first opening) 51d formed in the first enclosure 51 so as to face the front side. And a second speaker 56 controlled to emit sound waves of an audible frequency from a second mounting hole (third opening) 52b formed in the second enclosure 52 so as to face the front side of the machine. Is disposed.
[0036]
That is, the first speaker 55 that emits sound waves of inaudible frequencies and the second speaker 56 that emits sound waves of inaudible frequencies are isolated from each other with the partition plate 58 interposed therebetween. The “wind” is sent out only when the cone of the first speaker 55 vibrates. Therefore, if only the first speaker 55 is operated, only the game effect by “wind” can be performed, and if only the second speaker 56 is operated, only the game effect by “sound” is performed. In addition, by operating both speakers 55 and 56, it is possible to produce a game effect combining "wind" and "sound", so that the player can enjoy the game with a variety of game effects. Will be able to.
[0037]
Note that the opening (blower port) and the bass reflex duct are formed in the enclosure, not limited to those in the above-described embodiment, but in positions corresponding to requirements such as the stop button and the start lever in the pachinko slot machine. What is necessary is just to form. Furthermore, the bass reflex duct can be configured to be a labyrinth that is bent and extended, and by extending the entire length of the duct, it is possible to reproduce the sound up to a lower sound range. Furthermore, the bass reflex duct width is gradually expanded toward the output side (outside), so-called back-loaded horn type, so that the bass can be reproduced more strongly, so the sound output is crisp. Is possible.
[0038]
【The invention's effect】
As described above, according to the gaming machine of the present invention, the sound effect is achieved by forming the second opening that communicates the space and the outside in the enclosure in which the sound effect output device is provided. The output device can be operated to send the internal air in the enclosure to the outside through the second opening. Therefore, by operating the sound effect output device, the player can remember the feeling of being blown from the second opening, so that the game effect by “wind” can be achieved without providing a blower in the gaming machine. Can do. Moreover, the cost and work burden for newly installing the blower are not increased.
[0039]
Furthermore, if the sound effect output device is controlled to selectively emit sound waves in the audible area or non-audible area, it is possible to perform only the game effect by “wind” without producing “sound”. Game production can be increased. Further, the second opening for sending the internal air is provided at the upper position of the gaming machine to blow “wind” toward the player's face, or is provided in the vicinity of the hitting ball launching means. By blowing "wind" toward the game, the fun of the game is further increased. Furthermore, a sound effect output device controlled to emit an inaudible frequency is disposed in the enclosure having the second opening, and is isolated from the enclosure so that the internal space and the outside are not in communication. By providing the second enclosure and arranging the second sound effect output device controlled to emit sound waves of an audible frequency in the second enclosure, only “sound” can be output without blowing. It becomes possible.
