For explaining a preferred embodiment of the present invention, Fig. 1 is a perspective view showing a speaker box according to the present invention, Fig. 2 is a bottom perspective view of the speaker box according to the present invention, and Fig. 3 is a front view of the speaker box according to the present invention. and FIG. 4 is a side view of the speaker box according to the present invention, and FIG. 5 is a plan view of the speaker box according to the present invention. 6 to 12 are views showing an example of installation of a speaker box according to the present invention. FIGS. 6 to 8 show a state in which the speaker box of the present invention is coupled to a wiring protection duct, and FIG. 9 is a speaker box of the present invention. is installed on a wire, FIG. 10 shows a state in which the speaker box of the present invention is installed on a wall, and FIGS. 11 and 12 show a state in which the speaker box of the present invention is installed in an outlet box of the wall.

As shown in Figs. 1 to 5, the speaker box according to the present invention consists of a housing 10 and a cover member 20 in which the speaker and electric components are embedded, and is inserted from the rear surface of the housing 10 and the cover member ( It is configured to be integrated by a fastening screw 18 fastened to the 20 .

The housing 10 has a storage space in which a speaker and electric components are accommodated therein, a narrow portion accommodated in the wiring protection duct 30, and a narrow portion to be exposed to the outside of the wiring protection duct 30. made of a wide section. In addition, the wire insertion hole 15 is formed on the upper surface of the narrow portion forming the rear surface of the housing 10 so that wires connected to the speaker and the electrical components can be inserted.

And, as a means for installing the enclosure 10 to a wiring protection duct 30 fixed to a raceway or hanger rod installed on a ceiling such as a parking lot or an underground passage of a building, the enclosure The first locking part 11 and the narrow wire protection duct 30' are formed protruding so that the locking hooks 32 provided at the lower ends of the wide wire protection duct 30 are elastically coupled to both sides of the narrow part of (10). ), the second locking part 12 formed on the upper side of the first locking part 11 is provided so that the locking hook 32 provided at the lower end is elastically coupled. At this time, it is natural that the first locking part 11 and the second locking part 12 are symmetrically formed on both sides in the longitudinal direction of the housing 10 in order to maintain balance.

The wiring protection duct 30 is used for protection of electric wires or communication cables and for mounting lighting equipment. The upper and lower portions are open, and the main body in which the hooking hooks 32 are formed on both sides of the inner side of the upper and lower openings, respectively. (31) and an upper cover 33 elastically coupled to the upper opening of the main body 31 so as to seal the upper portion of the main body 31 for protection of electric wires and the like.

Accordingly, as shown in FIG. 6 , by making the first locking part 11 of the enclosure 10 hooked on the hooking hook 32 provided at the lower end of the wide wiring protection duct 30 , the enclosure 10 ) and the cover member 20 integrated with the speaker box can be fixedly installed in the wide wiring protection duct 30 . And, as shown in FIG. 7 , the second of the enclosure 10 is attached to the engaging hook 32 provided at the lower end of the wiring protection duct 30 formed to be narrow enough that the first engaging part 11 is not inserted. By hooking the locking part 12 , the speaker box in which the housing 10 and the cover member 20 are integrated can be fixedly installed in the narrow wiring protection duct 30 .

And, so that installation is possible even when the lower width of the wiring protection duct 30 is formed to be narrow enough that the second locking part 11 is not inserted, each of the upper surface corners of the narrow part of the housing 10 It is preferable that the screw fastening hole 13 is formed. In this case, the lower cover 35 elastically coupled to the lower opening of the wiring protection duct 30 is used. Specifically, as shown in FIG. 8 , the lower cover 35 is installed and fixed on the upper surface of the housing 10 using a plurality of assembly screws 36 respectively fastened to the screw fastening holes 13 , and then the By elastically coupling the lower cover 35 to the lower opening of the wiring protection duct 30 , the speaker box in which the housing 10 and the cover member 20 are integrated can be fixedly installed in the narrow wiring protection duct 30 . .

In the above, the installation of the speaker box in the wiring protection duct 30 has been described, but the speaker box of the present invention may be installed on the wire 40 in the horizontal or vertical direction provided in the basement or underground passage of a building.

In order to install the speaker box on the wire 40, a pair of through-holes 14 that penetrate the narrow portion of the housing 10 left and right and into which the fixing band 45 is inserted are formed symmetrically on both sides in the longitudinal direction. . Accordingly, as shown in FIG. 9 , a speaker box in which the housing 10 and the cover member 20 are integrated is installed on the wire 40 using the fixing band 45 inserted into the through hole 14 . can be fixed.

In addition, the speaker box may be installed in the basement of a building or the wall 60 of the underground passage without installing the speaker box in the wiring protection duct 30 or the wire 40 . To this end, bracket coupling holes 16 are respectively formed on both end surfaces in the longitudinal direction of the enclosure 10 , and the assembly member 55 is inserted into the bracket coupling hole 16 to attach the enclosure 10 to the installation bracket 50 . and a speaker box in which the cover member 20 is integrated is rotatably assembled.

As shown in FIG. 10 , the installation bracket 50 is formed in a shape in which both ends of the coupling surface in close contact with the wall 60 are bent toward the housing 10 . Therefore, the mounting bracket 50 can be fixedly installed on the wall 60 using a fixing member 65 made of a plurality of fixing screws or nails installed on the coupling surface, and the assembly member 55 is formed on the bent surfaces of both ends. By penetrating the hole formed in the housing 10 and inserting it into the bracket coupling hole 13 of the housing 10, the speaker box is rotatably assembled.

In addition, as shown in FIGS. 11 and 12 , the installation bracket 50 is not directly installed on the wall 60 but is fixedly installed in the outlet box 70 provided in the wall 60 by an assembly screw 75 . it might be At this time, a through hole 53 for connection with the inside of the outlet box 70 is formed in the center of the installation bracket 50 .

And, the width of the installation bracket 50 is used to correspond to the size of the outlet box (70). That is, as shown in FIG. 11 , when the outlet box 70 is formed in a square shape, the width of the installation bracket 50 is increased and the installation bracket 50 is connected to the outlet box 70 by four assembling screws 75 . and, when the outlet box 70 is formed in a rectangular shape as shown in FIG. 12, the width of the installation bracket 50 is narrowed, and the installation bracket 50 ) is to be fixed to the outlet box (70).

Although described and illustrated in relation to several embodiments for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as described above, and the scope of the technical idea described in the description of the invention It will be apparent to those skilled in the art that many changes and modifications can be made to the present invention without departing from the scope of the present invention. Accordingly, all such suitable alterations and modifications and equivalents are to be considered as being within the scope of the present invention.
