According to the dimensional relationships shown in FIGS. 4 and 6, when the speaker 52 is mounted on the back of the speaker case 51,
By assigning one shoulder 52h to one position determination unit 51n, the speaker 52 with respect to the speaker case 51 is placed.
If the upper and lower sides of the speaker case 51 are normal, both the speaker mounting holes 51m of the speaker case 51 and the two mounting holes 52g of the speaker 52 are aligned with each other. The speaker mounting hole 51m and both mounting holes 52g of the speaker 52 do not match each other.

Then, the leg 53c is inserted into the cover mounting hole 51d from the annular groove 51c, and the peripheral wall 53b is inserted into the annular groove 53c.
c, the front wall 53a entirely contacts the front surface of the front wall 51a other than the sound emission hole 51b of the speaker case 51, and the sound emission hole 51b is covered with the front cover 53.
In this state, the front cover 53 is attached to the speaker case 51 by bending the legs 53c protruding rearward from the cover attachment holes 51d inward.

That is, since the sound emitting hole 51b is covered with the front cover 53 made of a net, the portion surrounding the mesh is narrow, so that a clear sound effect can be emitted and the playability can be enhanced. That is, if the portion through which the sound effect emitted from the speaker 52 escapes is a so-called perforated metal structure in which a small hole is formed in the plate member, the portion surrounding the small hole becomes thick and a sound barrier, and the sound effect is muffled. Is difficult to hear. On the other hand, if the front cover 53 is a net as in the embodiment, the portion surrounding the mesh is thin and hardly acts as a sound barrier, and the sound effect passes through the front cover 53 without resistance, so that a clean sound effect can be emitted. It is.

Since the net of the front cover 53 is made of metal,
Even if an unauthorized member such as a piano wire is inserted from the front cover 53 to the direction of the speaker 52, the rigidity of the front cover 53 is higher than when the front cover 53 is formed of a net made of synthetic resin other than metal, for example. The front cover 53 appropriately prevents insertion of an unauthorized member.

Further, as shown in FIG. 7, since the sound emitting portion of the speaker device 5 is installed so as to face forward and inward, the sound effect emitted from the speaker device 5 does not annoy surrounding players. Instead, the surrounding players can concentrate on their own game.

Referring to FIG. 8, the attachment of the speaker 52 to the speaker case 51 will be described. The front surface of the front wall 51a of the speaker case 51 is placed on the worktable upper surface 13, and
The bracket 52f of the speaker 52 is
On the speaker mounting portion 51k. Then, the set screw 54 is fastened from the mounting hole 52g of the speaker 52 to the speaker mounting hole 51m of the speaker case 51. Thus, the speaker 52 is attached to the speaker case 51. In this embodiment, the speaker mounting hole 51m is formed in the speaker case 51 such that the center line indicated by the dashed line L of the speaker mounting hole 51m is perpendicular to the front surface of the front wall 51a. Due to the structure of the speaker case 51, the outer peripheral surface of the speaker mounting portion 51k is
h.

Therefore, the center line L of the speaker mounting hole 51 is inclined with respect to the outer peripheral surface of the speaker mounting portion 51k, but is orthogonal to the front surface of the front wall 51a and the work table upper surface 13. Therefore, when the speaker case 51 on which the speaker 52 is superimposed is placed on the workbench upper surface 13 and the set screw 54 is fastened, the set screw 54 is moved from the imaginary line position in the arrow X direction that is the same line as the center line L. Since it can be fastened to the position indicated by the solid line, a tool (not shown) such as a driver for operating the set screw 54 is perpendicular to the work table upper surface 13. Thus, the set screw 54
Can be operated at right angles to the workbench upper surface 13,
There are the following advantages. When the set screw 54 is manually tightened using a power drill, it is possible to prevent a side slip on the worktable upper surface 13 of the speaker case 51 and to secure safety. When the setscrew 54 is fastened by an automatic machine, a mechanism in which a fastening tool corresponding to a power drill is vertically moved up and down with respect to the work table upper surface 13 can be adopted, and the structure of the automatic machine can be simplified.

In FIG. 2, the speaker wiring passage 2c is provided at a portion different from the speaker escape portion 2b.
Although i is provided in the front decoration 2e, the same applies when the speaker wiring passage 2c is provided in the speaker escape portion 2b and the speaker wiring passage 2i is not provided in the front decoration 2e and is replaced with the speaker escape hole 2g.
