By the way, when a speaker is provided in a gaming machine, if the speaker grill is formed of a resin or the like integrally with a speaker base to which the speaker is attached, the thickness of the speaker grill is often relatively thick. Since the installation space is limited, it is not easy to secure the installation space when the speaker grill is thick. For this reason, it is conceivable to form the speaker grill in a thin plate shape.
However, if the speaker grill has a thin plate shape, the rigidity of the speaker grill is reduced, and when the player unexpectedly presses the speaker grill, the speaker grill is bent or pushed inward, and the speaker grill is damaged. There is a fear.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a gaming machine that can suppress the breakage of a thin speaker grill.

In order to achieve the above object, a gaming machine of the present invention is a gaming machine including a speaker base to which a speaker is attached, and a thin plate-like speaker grill attached to the speaker base in front of the speaker,
The speaker base includes a contact surface along an outer peripheral edge portion of the speaker grill, and a plurality of reinforcing portions protruding inward from the contact surface and provided at predetermined intervals in a circumferential direction of the contact surface. An outer peripheral edge portion of the speaker grill is in contact with the contact surface and the reinforcing portion.
Here, as long as the said contact surface is along the outer peripheral edge part of a speaker grille, the endless shape, ie, the irregular-shaped cyclic | annular form provided continuously may be sufficient, and it may be provided intermittently.

  In the present invention, the outer peripheral edge of the speaker grill can be reinforced from the back side by contacting the outer peripheral edge of the speaker grill to the contact surface and the reinforcing portion. For this reason, even if the player unexpectedly presses the speaker grille, the speaker grille is hardly bent or pushed inward, so that the speaker grill can be prevented from being damaged.

  The said structure of this invention WHEREIN: It is preferable that at least one part of the said reinforcement part does not overlap with the said speaker in front view.

  According to such a configuration, since at least a part of the reinforcing portion does not overlap the speaker, the entire reinforcing portion does not overlap the speaker in front view. For this reason, the fall of the aperture ratio of the speaker grille by having provided the reinforcement part can be suppressed.

  Here, the opening ratio of the speaker grille is that the speaker grille has a large number of through holes that allow sound to pass therethrough, so that the through hole for the area of the speaker when the speaker (cone) is viewed from the front. The ratio of the total opening area. Further, when the reinforcing portion as described above exists between the speaker grill and the speaker, at least a part of the reinforcing portion overlaps with the speaker when viewed from the front, so that the overlapping area is reduced from the total opening area. Of the area of the speaker.

Further, in the configuration of the present invention, a front member is provided in front of the speaker grille,
An outer peripheral edge portion of the speaker grill may be sandwiched between the front member and the contact surface.

  According to such a configuration, the outer peripheral edge of the speaker grill can be reinforced by the front member and the contact surface, and the speaker grill can be securely fixed.

  According to the present invention, the outer peripheral edge of the speaker grill is reinforced from the back side by the contact surface and the reinforcing portion, so that even if the player unexpectedly presses the speaker grill, the speaker grill is bent or pushed inward. This makes it difficult to damage the speaker grill.

And a plurality of reinforcing portions 122 provided at predetermined intervals. In addition, as long as the contact surface 121 is along the outer-periphery edge part of the speaker grille 103, the deformed annular shape provided continuously may be sufficient, and it may be provided intermittently.
The contact surface 121 is formed on the tip surface of the peripheral wall 120. The contact surface 121 is formed substantially along the outer peripheral edge of the speaker grill 103. That is, as shown in FIG. The contact surface 121 protrudes slightly above the outer peripheral edge of the speaker grill 103 at the upper right side and the lower center of the speaker grill 103, and slightly inward from the outer periphery of the speaker grill 103 at the right side of the speaker grill 103. positioned. The outer peripheral edge of the speaker grille 103 and the contact surface 121 may be substantially the same shape. That is, the outer peripheral edge portion of the speaker grille 103 and the contact surface 121 may substantially overlap in a front view.

As shown in FIGS. 2 and 4, the reinforcing portion 122 is formed on the inner surface of the upper surface wall 102 a and the lower surface wall 102 b of the peripheral wall portion 120, respectively. Further, the reinforcing portion 122 is constituted by a ridge 122 formed to protrude inward from the inner surfaces of the upper surface wall 102a and the lower surface wall 102b. The reinforcing portions (projections) 122 extend in the axial direction of the peripheral wall portion 120 and are arranged at predetermined intervals on the left and right. The reinforcing portion 122 may be formed on the left side wall 102c and the right side wall 102d.
As shown in FIG. 2, the front and rear widths of the lower surface wall 102b increase toward the right side. Therefore, the lengths of a plurality (three) of the reinforcing portions 122 formed on the inner surface (upper surface) of the lower surface wall 102b. Is longer toward the right. Further, since the front and rear widths of the upper surface wall 102a become wider toward the right side, the lengths of the plurality of (three) reinforcing portions 122 formed on the inner surface (lower surface) of the upper surface wall 102a also increase toward the right side. It is getting longer.
Furthermore, as shown in FIG. 9, when the speaker 101 is viewed from the front, the left and right width dimensions of the plurality of reinforcing portions 122 are substantially equal, and the plurality of reinforcing portions 122 formed on the inner surface of the lower surface wall 102b are The height (the height from the inner surface of the lower surface wall 102b) is lower toward the right side, and the height of the plurality of reinforcing portions 122 formed on the inner surface of the upper surface wall 102a (the height from the inner surface of the upper surface wall 102a). ) Is almost equal. Further, in the plurality of reinforcing portions 122 formed on the inner surface of the lower surface wall 102b, the ratio of the right-side reinforcement blocking the front surface of the speaker 101 is larger. The leftmost reinforcing portion 122 does not overlap the front surface of the speaker 101, and the plurality of reinforcing portions 122 formed on the inner surface of the upper surface wall 102a block the front surface of the speaker 101. The ratio is almost equal. Further, the upper surface of the reinforcing portion 122 (the surface facing the inside of the speaker base 102) is formed in a substantially semi-cylindrical surface shape, and the front end surface 122a of the reinforcing portion 122 is substantially flush with the contact surface 121.
In addition, in this Embodiment, although the reinforcement part 122 is the protruding item | line extended in the axial direction of the surrounding wall part 120, it is not restricted to this. For example, the convex part which protrudes from the inner surface of the surrounding wall part 120 and has the contact surface substantially flush with the contact surface 121 may be sufficient.

  As shown in FIG. 6, the speaker grill 103 is a punching metal formed of a thin metal plate and has a large number of through holes 103a that allow passage of sound. In addition, a substantially semicircular engaging portion 103b that engages with a part of the mounting portion 108 is formed on the right lower edge portion of the outer peripheral edge portion of the speaker grill 103, and the right upper edge portion has the above-described engagement portion 103b. A substantially quarter-circle engaging portion 103 c that engages with a part of the attaching portion 107 is formed.

As shown in FIGS. 5 and 7, the speaker grill 103 has a back surface of the outer peripheral edge thereof in contact with the contact surface 121 of the speaker base 102 and the front end surface 122 a of the reinforcing portion 122. In this state, as shown in FIG. 5, the engaging portion 103 b and the engaging portion 103 c of the speaker grill 103 are engaged with the attaching portion 108 and the attaching portion 107 of the speaker base 102, respectively. As a result, the speaker grill 103 is positioned (in the vertical and horizontal directions) with respect to the speaker base 102.
The outer peripheral edge portion of the speaker grill 103 is sandwiched between the front member 110 and the contact surface 121. That is, screws (not shown) are inserted from the rear into the mounting holes 106a, 107a, 108a (see FIG. 2) of the speaker base 102 having the contact surface 121, and the screws are screwed into holes provided on the back side of the front member 110. As a result, the speaker base 102 is attached to the front side member 110, and the contact surface 121 is thereby pressed against the receiving surface 110a provided on the back side of the front side member 110. The front member 110 is sandwiched between the receiving surface 110 a and the contact surface 121.

Further, as shown in FIGS. 5 and 8, the reinforcing portion 122 only overlaps with about ten of the many through holes 103 a of the speaker grille 103 in a front view.
In addition, as shown in FIG. 9, in the front view of the speaker base 102, at least a part of the reinforcing portion 122 provided on the speaker base 102 does not overlap the speaker 101. These are the upper end portions of the lower two reinforcing portions 122 and the upper three reinforcing portions 122 of the portions 122. Further, the upper three reinforcing portions 122 are lower in projecting height than the three lower reinforcing portions 122.
Accordingly, it is possible to suppress a decrease in the aperture ratio of the speaker grill 103 due to the provision of the reinforcing portion 122.

  As described above, according to the present embodiment, the speaker base 102 is provided with a deformed annular contact surface 121, protrudes inward from the contact surface 121, and is provided at predetermined intervals in the circumferential direction of the contact surface 121. And the outer peripheral edge of the speaker grille 103 is in contact with the contact surface 121 and the reinforcing part 122. Therefore, the outer peripheral edge of the speaker grille 103 is formed by the contact surface 121 and the reinforcing part 122. Can be reinforced from the back side (back side). For this reason, even if the player unexpectedly presses the speaker grill 103 from the front side, it is difficult for the speaker grill 103 to be bent or pushed inward, so that damage to the speaker grill 103 can be suppressed.

In addition, at least a part of the reinforcing portion 122 does not overlap the speaker 101 when viewed from the front, but overlaps the upper ends of the two lower reinforcing portions 122 of the six reinforcing portions 122 and the upper portion. Since the three reinforcing portions 122 are provided, the entire reinforcing portion 122 does not overlap the speaker 101 when viewed from the front. For this reason, the fall of the aperture ratio of the speaker grille 103 by having provided the reinforcement part 122 can be suppressed.
Further, as shown in FIG. 9, in the plurality of reinforcing portions 122 formed on the inner surface of the lower surface wall 102 b, the portion on the right side closes the front surface of the speaker 101, and the leftmost reinforcing portion 122. Does not overlap the front surface of the speaker 101. And the reinforcement part 122 located in the leftmost side which does not overlap in this way has the highest height, and the reinforcement part 122 located sequentially in the right side from it has the height sequentially lower. Therefore, a decrease in the aperture ratio of the speaker grill 103 can be suppressed while the outer peripheral edge of the speaker grill 103 is sufficiently reinforced from the back side (back side) by the reinforcing portion 122.
Further, the resin speaker grill has a lower aperture ratio than the speaker grill made of punching metal, but in this embodiment, the speaker grill 103 is made of punching metal. The aperture ratio can be prevented from decreasing.

In addition, by bending the end portion of the thin plate-shaped punching metal, the strength of the outer peripheral edge of the punching metal can be increased, but on the other hand, the processing cost for the bending processing is increased. Since the outer peripheral edge portion of the speaker grill 103 formed of a punched metal is in contact with the contact surface 121 and the reinforcement portion 122, the contact surface 121 and the reinforcement portion 122 can be obtained without performing the bending process described above. Thus, the outer peripheral edge of the speaker grill 103 can be reinforced.
In addition, the front member 110 is provided in front of the speaker grill 103, and the outer peripheral edge of the speaker grill 103 is sandwiched between the receiving surface 110a of the front member 110 and the contact surface 121 of the speaker base 102. The outer peripheral edge of the grill 103 can be reinforced by the receiving surface 110a and the contact surface 121, and the speaker grill 103 can be securely fixed.
