61 to T612 are for preventing jitter due to vibration when the speaker is operated with the set main body 11 and the speaker boxes 30, 31 assembled together.

Furthermore, in the state shown in FIG. 21, the operating portion γ01 of the locking member 70 of the hinge 35 comes into contact with one side of the notch 371 of the set main body 11, as shown in FIG.
The set main body 11 and the speaker box 31 cannot be easily separated.

On the other hand, FIGS. 23a and 23b show the hinge 35 stored in the housing 351 of the speaker box 31. When the hinge 35 is stored in the housing 351, its side surface and the engaging portion 702 The elastic members 67, 68 and 69 come into contact with the surfaces on which the hinge 35 is not provided, and the hinge 35 is held in the storage portion 351 so that it does not wobble.

Further, the elastic members 67, 68 are formed with protrusions 671, 681, and these protrusions 671, 681 engage the engagement portion 353 of the hinge 35 and the engagement member TO, as shown in FIG. 702, and prevents the hinge 35 from easily coming out of the housing portion 351.

Here, according to the above five configurations, the speaker box 3
1 from the set main body 11 and the hinge 35 is removed from the storage section 3.
Since the hinge 35 does not wobble even if the speaker is operated while it is housed in the speaker 51, it is possible to prevent the speaker from shaking due to vibration.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

Therefore, as detailed above, according to this invention, the set body is provided with a connecting shaft, and the bay-shaped engaging portion into which the connecting shaft can be fitted and the opening of the engaging portion are approximately opened and closed. Since the hinge body has a locking member at one end and is rotatably connected to the speaker box at the other end, the set body and the speaker box can be organically attached and detached, and the attachment and detachment operation is easy. It is possible to provide an extremely good hinge mechanism that can be easily and securely attached.
