Further, a power supply board box 240 having a power supply board, a frame control board box 234 having a frame control board, and the like are attached to the central portion of the lower region of the mechanism mounting body 160.

[Operation and effect of embodiment]
The gaming machine according to this embodiment is configured as described above.
Accordingly, during the game, for example, when the symbols displayed on the display surface 49 of the symbol display device 48 are variably displayed, when the reach state is reached, when the jackpot is reached, etc. The speaker 94 is operated based on a signal transmitted from a sound control circuit configured on the control board. Then, a sound generated by the operation of the speaker 94 is output in front of the gaming machine. In addition, sound due to the operation of the speaker 94 is emitted forward from the acoustic opening 85 through the acoustic chamber 71 and the acoustic passage 80 of the speaker box 70.

In the gaming machine according to this embodiment, the main body frame 30 includes a game board mounting frame 31 and a mechanism mounting body 160 and is integrally formed of a synthetic resin material. The direction depth dimension also increases.
Simultaneously with the formation of the main body frame 30, the speaker box 70 having a large depth dimension can be obtained favorably by integrally forming the box-shaped speaker box 70 opened forward. Furthermore, the speaker 94 can be stably attached to the opening of the speaker box 70.
Thus, a sealed acoustic chamber 71 can be formed between the rear side of the cone (diaphragm) 99 of the speaker 94 and the rear wall portion 75 of the speaker box 70.
Furthermore, it is possible to save the trouble of forming and attaching a speaker box separately from the main body frame 30 to the front side of the main body frame 30, and the structure becomes very simple.

In particular, the speaker box 70 is formed large with a depth dimension in which the rear wall portion 75 exceeds the rear side of the game board mounting frame 31. For this reason, it is possible to satisfactorily suppress the movement of the cone (diaphragm) 99 of the speaker 94 from being hindered by sound waves generated in the acoustic chamber 71 when the speaker 94 is operated.
In other words, the depth dimension of the speaker box 70 is large enough to prevent the movement of the cone (vibration plate) 99 of the speaker 94 from being hindered by sound waves generated in the acoustic chamber 71 when the speaker 94 is operated. Can be set easily.
In addition, the speaker 94 can be mounted stably and firmly by integrally forming the box-shaped speaker box 70 that opens to the front simultaneously with the molding of the main body frame 30 having a large size, high rigidity, and a large depth dimension in the front-rear direction. In addition, it is possible to prevent abnormal sounds such as chattering noises and leakage of sound waves having opposite phases in the acoustic chamber, and the acoustic effect can be improved satisfactorily.

Further, when the speaker 94 is in operation, it is possible to suppress the vibration (resonance) of the main body frame 30 due to the vibration of the cone (diaphragm) 99 of the speaker 94.
Thereby, for example, it is possible to prevent a problem that the firing rail 100 and the firing hammer 233 of the launching device are vibrated unexpectedly due to vibration during operation of the speaker 94. As a result, it is possible to prevent a launch failure in which the launch state of a ball (pachinko ball) launched from the launch position of the launch rail 100 by the launch hammer 233 changes unexpectedly.
In addition, a speaker box 70 is formed on the other side portion opposite to the launching device disposed on one side portion of the main body frame 30. As a result, the speaker box 70 can be formed at a position far from the launching device, so that it is possible to reduce the transmission of vibration during operation of the speaker 94 to the launching device.
In other words, due to vibration transmission during operation of the speaker 94, it is possible to satisfactorily prevent a launch failure caused by unexpectedly changing a ball (pachinko ball) launched from the launch position of the launch rail 100. .

As shown in FIGS. 8 to 10, the inner wall portion (the inner wall surfaces of the upper wall portion 72, the lower wall portion 73, and the left and right side wall portions 74) of the speaker box 70 is wide at the opening side and narrow at the back side. It is formed into a shape. For this reason, the strength of the speaker box 70 can be improved satisfactorily, the vibration of the speaker box 70 when the speaker 94 is activated can be suppressed well, and the effect of preventing the vibration of the main body frame 30 is great.
Further, since the inner wall portion of the speaker box 70 formed in a stepped shape has a wide opening side and a narrow back side, for example, after the speaker box 70 is formed simultaneously with the molding (for example, injection molding) of the main body frame 30 by a synthetic resin material. When removing the mold, it is possible to prevent a problem that the removal of the main body frame 30 becomes difficult due to the speaker box 70.
Further, the inner wall portion of the speaker box 70 is formed on an inclined surface or a tapered surface that is inclined so that the opening side is wide and the back side is narrow, so that the main body frame 30 can be removed more easily.

In this embodiment, when the speaker 94 is attached to the speaker box 70, first, the flange portion 96 of the speaker frame 95 is fitted into the concave portion 91 of the speaker attachment plate 90 and attached by screws. Thus, the speaker 94 can be easily mounted on the speaker mounting plate 90 with the speaker 94 positioned.
Next, the folding edge 90b of the peripheral portion of the speaker mounting plate 90 is fitted so as to cover the outer surface of the annular protrusion 70a and the boss portion 70b formed at the periphery of the opening of the acoustic chamber 71 of the speaker box 70. . Thereafter, by screwing a screw into the boss portion 70b of the speaker box 70 through the mounting hole of the speaker mounting plate 90, the speaker mounting plate 90 can be easily and displaced so as to close the opening of the acoustic chamber 71 of the speaker box 70. (See FIGS. 8 to 10).
As described above, the speaker 94 can be stably and firmly attached to the speaker box 70 by the speaker attachment plate 90, and the acoustic performance during operation of the speaker 94 can be improved.

Further, on the back side of the speaker mounting plate 90, an elastic body such as silicone rubber which is fitted between the folded edge 90b and the outer portion of the recess 91 and corresponds to the annular protrusion 70a on the front edge of the speaker box 70 is provided. A substantially square annular vibration-proof packing 93 is attached.
And the speaker 94 is mounted | worn through the vibration-proof packing 93 and the speaker mounting plate 90 in the opening part of the acoustic chamber 71 of the speaker box 70 (refer FIGS. 8-10).
For this reason, vibration during operation of the speaker 94 is absorbed by the vibration-proof packing 93. As a result, vibration during operation of the speaker 94 can be prevented from being transmitted to the main body frame 30, and vibration (resonance) of the main body frame 30 due to vibration transmission can be satisfactorily suppressed.

As shown in FIGS. 6 and 10, the acoustic effect can be enhanced by an acoustic passage 80 provided such that one end thereof communicates with the acoustic chamber 71 and the other end opens to the front side of the main body frame 30.
That is, the acoustic passage 80 has a required cross-sectional area and passage length so that the sound wave having the opposite phase generated in the acoustic chamber 71 when the speaker 94 is operated can be reversed to the normal phase and emitted forward. By setting, an acoustic path for bass reflex can be easily set, and the acoustic effect can be enhanced.
In this embodiment, the slide member 83a, 84a of the duct member 81 is inserted into the slide grooves 78, 78a of the one side wall portion 74a from the front side of the acoustic chamber 71. By sliding to a predetermined position where it abuts on the stepped portion or the rear wall portion 75, the duct member 81 is positioned and accurately mounted on the one side wall portion 74a. As described above, when the duct member 81 is attached to the one side wall portion 74 a of the acoustic chamber 71, the acoustic opening portion 85 is opened forward by the cooperation of the one side wall portion 74 a and the duct member 81. The acoustic passage 80 is easily configured.

Further, in the acoustic passage 80, a concave strip 76 is formed on one side wall 74a of the acoustic chamber 71, and a flat duct member is attached so as to close the concave strip 76 of the one side wall 74a. Can also constitute an acoustic path.
The acoustic path can also be configured by mounting a duct member 81 having a concave portion and having a substantially semi-cylindrical cross section on the flat surface of one side wall 74 a of the acoustic chamber 71.

[About other embodiments]
In addition, this invention is not limited to the said Example.
For example, in the above-described embodiment, the duct member 81 is attached to the inner wall surface of the acoustic chamber 71 of the speaker box 70, one end communicates with the back side of the acoustic chamber 71, and the other end opens to the front side of the main body frame 30. Although the case where the acoustic passage 80 having the long acoustic path 80 having the acoustic opening 85 is provided is illustrated, the present invention is implemented even in a sealed speaker box in which the acoustic passage 80 is not provided. Can do.
Further, the present invention can be adopted even in gaming machines other than pachinko machines, for example, slot machines.

  Moreover, the said Example contains the other invention described below.

“A gaming machine with a speaker,
A speaker box having an acoustic chamber is integrally formed on the synthetic resin frame disposed at a predetermined position of the gaming machine,
A gaming machine, wherein a speaker is attached to the opening of the speaker box via a vibration isolating member. Is the gist.
Here, the frame means a front frame called an inner frame, a front frame or the like, a main body frame integrated with a front frame and a mechanism plate, a glass frame, or the like.

The said structure WHEREIN: The vibration at the time of a speaker action | operation can be absorbed by the vibration isolator. As described above, the vibration isolating member can prevent the vibration at the time of operating the speaker from being transmitted to the frame body, and can satisfactorily suppress the vibration (resonance) of the frame body due to the vibration transmission.
For example, as is generally done conventionally, when the speaker mounting part of the frame body is mounted in direct contact with the speaker body separate from the frame body without interposing an anti-vibration member, The vibration when the speaker is activated is transmitted to the frame through the contact portion with the speaker box. Then, the frame body vibrates (resonates) due to vibration transmission when the speaker is activated, and the acoustic effect may be reduced or abnormal noise may be generated.
Therefore, it is conceivable to mount the speaker box separate from the frame with a vibration isolating member interposed on the speaker mounting portion of the frame. However, in this case, it is necessary to interpose a vibration isolating member at the entire contact portion between the frame and the speaker box, which requires a lot of work and time.
In order to solve such problems, a speaker box having an acoustic chamber is formed integrally with a synthetic resin frame, and the speaker is attached to the opening of the speaker box via a vibration isolating member. did.
In this way, vibration transmission of the speaker to the frame can be suppressed by an extremely simple structure in which the speaker is attached to the opening of the speaker box integrated with the frame via the vibration isolating member. It is possible to prevent a reduction in acoustic effect and abnormal noise caused by vibration.

In a gaming machine according to means 2 as a dependent claim of means 1 of another invention, the speaker is provided with a mounting member,
An anti-vibration member is interposed between the mounting member and a peripheral portion of the opening of the speaker box, and is interposed.
Accordingly, the vibration isolating member can be easily interposed between the speaker mounting member and the peripheral portion of the opening of the speaker box, and the vibration transmission of the speaker to the frame can be transmitted by the vibration isolating member. It can suppress well.

In the gaming machine according to means 3 as a dependent claim of means 1 or 2 of another invention, the vibration isolating member is constituted by an anti-vibration packing made of an elastic body.
Therefore, since vibration at the time of speaker operation can be favorably absorbed by the elasticity of the vibration-proof packing, vibration transmission to the frame body at the time of speaker operation can be reliably suppressed.
