The sound from the mouth 75 is prevented from diffusing. The passage walls 81 and 82 may be provided on both the door plate 69 and the decorative cover 71, or may be provided on either one.

  The firing handle 18 is rotatably provided on the holding case 85. The holding case 85 passes through the hole of the recessed portion 78 of the decorative cover 71, and is fixed with the door plate 69 and the reinforcing plate 70 sandwiched between the bottom plate 83 on the lower side of the medium sound outlet 75. On the back side of the opening / closing door 6, ball feeding means 84 is provided for supplying game balls from the supply tray 16 one by one onto the firing rail 37 in conjunction with the launching operation of the launching means 8.

  In a ball game machine with such a configuration, when a big hit or the like occurs during the game, a sound effect is generated by the pair of upper left and right speakers 15 and one lower speaker 25 to change the gaming state. Produce acoustically. In this case, since bass reflex type speaker 25 is arranged at the lower part, a low-pitched sound effect can be generated.

  Further, since the speaker 25 houses the speaker unit 51 in the speaker box 50, it is very easy to handle when assembling and disassembling, and damage to the diaphragm of the speaker unit 51 can be minimized.

  Since the storage box 44 that forms the speaker storage chamber 43 is formed integrally with the support plate 28 and the speaker 25 is stored in the storage chamber 43, the speaker box 50 is fitted to the support plate 28 from the front side. Since the opening to be formed is formed, there is an advantage that the strength of the lower side of the front frame 4 including the support plate 28 is improved as compared with the case where the back side of the speaker box 50 is open. For this reason, the speaker box 50 can be enlarged.

  Further, the mounting plate 49 on the front surface of the speaker box 50 has a fraud prevention wall 67 extending in the left-right direction at the upper edge thereof, and a vertical fraud prevention wall extending downward from the fraud prevention wall 67 on the side edge on the launching means 8 side. 68, it is illegal to insert unauthorized members such as piano wires from the sound outlets 19, 20, and 75 of the door 6 to add unauthorized work to the game board 7, the launching means 8, the locking means 24, etc. Further intrusion of the member can be prevented by the fraud prevention walls 67 and 68. For this reason, it is possible to prevent illegal acts such as illegally bending the game nails of the game board 7 or illegally operating the winning means.

  Further, since there is an inner wall 87 projecting forward in the vicinity of the speaker box 50 on the locking means 24 side, unauthorized members such as piano wires are inserted from the sound outlets 19, 20, 75 of the opening / closing door 6 to lock the locking means 24. It is also possible to prevent fraudulent actions to cancel.

  The open / close door 6 includes a door plate 69 and a decorative cover 71 spaced apart from each other in the front and rear, and a large number of small hole-like sound exits 19, 20, and 75 are formed in both of them. Compared with the case where one or several large sound emission openings are provided, not only is it difficult to insert the unauthorized member into the mounting plate 49 side, but even if the unauthorized member can be inserted, It becomes difficult to operate the illegal member. For this reason, an illegal act such as bending an illegal member by inserting an illegal member over the anti-fraud walls 67 and 68 toward the game board 7 and bending a specific game nail is extremely difficult.

  Further, since the front sound emission port 20 formed in the bottom wall 79 of the recessed portion 78 of the decorative cover 71 is smaller than the front sound emission port 19 in the vicinity thereof, the bottom wall 79 is close to the door plate 69. Nevertheless, it is difficult to insert a piano wire or the like from the previous sound emission opening 20.

In this embodiment, a front box 52 is mounted on the front side of the storage box 44 of the support plate 28, and the front box 52 and the storage box 44 constitute a speaker box 50. A fitting portion 90 is formed at the front end of the storage box 44, and the rear end of the front box 52 is fitted into the fitting portion 90. Note that the structure for attaching the front box 52 to the support plate 28 and other configurations may be the same as those in the first embodiment.

  In this case, since the storage box 44 also serves as a part of the speaker box 50, the number of components can be reduced. Further, since the back side of the storage chamber 43 is closed by the storage box 44, it is possible to prevent a decrease in strength on the lower side of the front frame 4.

  FIG. 12 illustrates a third embodiment of the present invention. In this embodiment, the support plate 28 is formed with fitting portions 92, 93 in the circumferential direction before and after the opening 91, and the rear end portion of the front box 52 is fitted to the front fitting portion 92 on the back side. The front end portion of the rear box 53 is detachably fitted to the portion 93 and is detachably fixed to the support plate 28 from both the front and rear sides by screws 96 and 97 which are screwed to the outer mounting portions 94 and 95 thereof. .

  In this case, the support plate 28 has an opening 91 for the speaker 25, and the support plate 28 itself is open on both the front and rear sides of the opening 91, but the front box 52 and the rear box 53 are fitted on both the front and rear sides. Since it is mounted in the combined state, the support plate 28 can be reinforced by the boxes 52 and 53.

  As mentioned above, although each Example of this invention was explained in full detail, this invention is not restricted to each Example, A various change is possible. For example, the lower speaker 25 does not have to be a bass-reflex type, and may be a simple sealed type or another type of speaker 25. When the speaker 25 is a bass reflex type, a large number of small sound emission ports may be provided instead of the front sound emission duct 80 on the door 6 side.

  In the embodiment, the speaker 25 is mounted on the lower support plate 28 of the front frame 4 and the opening and closing door 6 disposed on the front side of the speaker 25 is provided with sound emission ports 19, 20, and 75. However, the support plate 28 is not limited to the lower portion of the front frame 4, and may be provided at the upper portion or other locations. In that case, the support plate 28 may be covered with the front cover from the front side. Therefore, the open / close door 6 is only an example of a front cover that covers the support plate 28 from the front side.

  The mounting plate 49 of the embodiment is provided on the front surface of the front box 52. However, the attachment plate 49 may be a flat plate and may be attached to the front surface of the support plate 28 or the speaker box 50 corresponding to the opening 63. In addition, the present invention is not limited to a ball game machine such as a pachinko machine, an arrangement ball, or a sparrow ball game machine, but can be similarly implemented in various game machines such as a slot machine.
