TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gaming machine such as a pachinko gaming machine, a slot machine, a sparrow ball machine, a pachislo machine, and a gaming machine used in a game center, and more particularly to an acoustic structure used for a box-type gaming machine.
[0002]
[Prior art]
As is well known, in a gaming machine, particularly a slot machine which is one of box-type gaming machines, a plurality of reels are rotated by operating a start lever or a start button, and each reel is operated by operating a stop button. Of the reels are sequentially stopped, and a medal or a ball is paid out according to a combination of the symbols on the reel when the rotation is stopped.
[0003]
In the slot machine, the number of payouts of medals and balls differs according to winnings and special winnings in the game process, so timely sound effects are generated when winnings or special winnings are established or medals or balls are paid out. In some cases, the interest of the player may be enhanced in this way.
[0004]
The slot machine has a hollow housing body capable of accommodating various driving units such as reels and control devices for these driving units, and a front door having a game operation surface supported by the opening and closing freely. It is configured.
Speakers for producing sound effects in such an airframe are generally mounted near the metal or ball payout opening on the front door, and further near the upper portion of the front door corresponding to a position close to the player's ear. Often. (For example, Patent Document 1).
In addition, if the front door alone is used, the size of the speaker tends to be small due to the small installation space of the speaker, which tends to make the sound effect sound volume insufficient. To solve this problem, the front door is supported so that it can be opened and closed. There is also proposed a configuration in which a speaker box is arranged inside a side wall on the side of the housing, and a speaker is provided inside the box (for example, Patent Document 2).

[Problems to be solved by the invention]
It is desirable that the sound effect be recognized directly by the player without being disturbed by the atmosphere sound of the game hall where the slot machine is installed, but the same effect sound is emitted from the slot machine around the player, There is a case where the degree of recognition of the player is low due to the influence of broadcasting inside the amusement arcade. That is, the output of the sound effect from the slot machine may be felt small due to noise or the like around the player. For this reason, in the game process, it may be difficult for the player to obtain an amusement or an urgency to increase a sense of urgency or a win at the time of winning or special winning.
It is not always desirable to always increase the sound effect to the player, and the loudness of the sound effect may hinder the concentration of the adjacent players or may give a sense of discomfort in the hall. In some amusement arcades, a circulating machine for prize balls, such as a pachinko ball, may be installed near a slot machine, and in this case, sound generated from the circulating machine may interfere with sound effects. Sound effects may be difficult to hear.
Further, in the case of a configuration in which a speaker box is provided as shown in Patent Document 2 as a configuration in the case where the sound volume as a sound effect is small, an increase in volume can be expected by using the speaker box as a cavity, but the front door Sound is radiated from a direction different from the speaker provided in the player, and the player may be confused. In addition, the configuration using the cavity has a so-called bass reflex configuration, which has the advantage that bass can be emphasized.On the other hand, the portion that emits bass has many shapes such as a circle, and this shape must be formed in the cavity. Is often difficult in molding and the like. In particular, when providing a step-like partition as disclosed in Patent Document 2, it is extremely difficult to integrally mold with the cavity, and it is provided in a separate process from the cavities. There is a disadvantage in that the processing cost for securing the directivity of the sound increases.
[0007]
On the other hand, the speaker provided on the front door is often directly mounted on the back side of a lath hole or a slit hole formed on the front door. For this reason, in places where the inside of the slot machine communicates with the outside, such as lath holes and slit holes, a rod-shaped member is inserted from the outside to break the speaker cone paper and gain unauthorized access to internal parts. Have been reported. If this illegal operation is performed, the payout mechanism of the metal or the ball may be easily operated, and there is a possibility that an illegal payout may be performed.
[0008]
SUMMARY OF THE INVENTION An object of the present invention is to provide an optimal sound effect according to the sound field atmosphere in a venue without impairing the interest to a player, in view of the above-described problems in the conventional slot machine, particularly the installation structure of a speaker used as an audio device. An object of the present invention is to provide a slot machine capable of obtaining a configuration as an acoustic device serving as a generation source without increasing costs.
