DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the drawings. However, the shape of the components described in this embodiment, the relative arrangement, etc., are not intended to limit the scope of the present invention to only those unless otherwise specified, and are merely explanatory examples. Nothing more. 1 and 2 show an embodiment of an embedded speaker device of the present invention. FIG. 1 is a perspective view of a speaker body 10, and FIG. 2 shows a state in which the speaker body 10 is embedded in a mounting hole of a ceiling 16 and a decoration (front surface). ) A perspective view showing the panel 24. As shown in FIG. 2, a connector portion (wiring portion) 26 for connecting the speaker cord 12 is provided on the surface of the speaker body 10 (the surface that is not hidden behind the ceiling, the ceiling lower surface side). Further, as shown in FIGS. 1 and 2, a guide groove 30 for inserting and inserting the speaker cord 12 is provided on the side surface of the speaker body 10 and on the flange portion (a flange portion that hits the ceiling when embedded) 28. ing. 32 is a speaker and 34 is a sound-transmitting net.

When the speaker device of the present invention is mounted on the ceiling, the work of mounting the speaker body 10 on the ceiling 16 may be completed first, and then the wiring work may be performed again. That is, make a mounting hole in the ceiling. The speaker cord 12 is hung from the mounting hole. The speaker body 10 is attached to the ceiling surface. The speaker cord 12 is connected to the speaker body 10. That is the work process. The operations from to that follow are not required to be performed all at once. That is, it is possible to separately perform the “mounting work on the ceiling” and the “wiring work for speaker cords” without performing the temporary fixing work. At this time, the mounting holes on the ceiling may be the same simple round holes (or square holes) as before. There is no need to make a specially shaped mounting hole. Furthermore, as another advantage, even after the speaker main body 10 is mounted on the ceiling 16, the connector portion (wiring portion) 26 is exposed on the front side, so that the speaker main body 10 is purposely mounted on the ceiling to confirm the connection state.
