The plurality of wirings 42 are connected from the front side to the speaker connection terminals 32 and 33 of the terminal 31b of each divided peripheral edge 23.
(Around edge cover 22)
As shown in FIG. 4, the peripheral edge cover 22 has a plurality of pre-split covers (front covers) 22a. As shown in FIGS. 10 and 10C, the pre-split cover 22a is formed such that the side surface shape conforms to the arc shape of the tip of the connecting member 38. Moreover, the pre-division cover 22a includes the speaker mounting plate portion 23c and the wiring groove 37 of the division peripheral edge 23, and the front engagement protrusions 41 and 41 of the connecting member 38 engaged with both ends of the division peripheral edge 23.

  The pre-split cover 22a can be a breathable metal plate in which a large number of vent holes are formed by punching, or a breathable metal plate in which a large number of vent holes are formed by etching or the like. Further, as the pre-division cover 22a, a breathable wire mesh cover in which a metal mesh is attached to a metal frame or a breathable cloth cover having a structure in which a cloth is attached to a metal frame can be used. Of course, as the pre-division cover 22a, a frame provided with a vent hole formed of resin, or a cover with a saran net covered thereon can be used.

  In such a pre-split cover 22a, the upper edge portion and the lower edge portion are respectively locked in the cover locking grooves 36 and 23b4 of the division peripheral edge 23.

Further, a thin monitor TV 43 is attached to the wall 5 as shown in FIG. 31b. Reference numeral 45 denotes a chair used for viewing the monitor TV 43.
[Action]
Next, the operation of the speaker system having such a configuration will be described.

  In such a speaker system, a speaker 29 is formed by forming a peripheral edge (building material) 20 of a building, which is a speaker system, from a peripheral edge main body 21 and a peripheral edge cover 22 and incorporating it into a divided peripheral edge 23 of the peripheral edge body 21. , 30, and the duct terminal member 31 are covered with the cover 22a before division of the peripheral cover 22, so that the speakers 29, 30 and the duct terminal member 31 are not exposed in the room, so that they are beautiful. There will be no damage.

  When a user sitting on the chair 45 views the monitor TV 43, the audio signal from the sound source unit 44 of the monitor TV 43 is sent to the speakers 29 and 30 incorporated in the peripheral edge 20 via the wiring 42. The speakers 29 and 30 vibrate based on the audio signal, and sound waves are emitted from the speakers 29 and 30 and the duct 31a. This sound wave is transmitted to the user sitting on the chair 45 in the living room 1 through the pre-division cover 22a.

  Even in this case, since the speakers 29 and 30 and the duct terminal member 31 are not exposed, the user can appreciate the monitor television 43 without being aware of the speakers 29 and 30 and the duct terminal member 31.

  In addition, since the spaces in the adjacent divided peripheral edges 23 and 23 are shielded by the end wall member 24 and the connecting member 38 made of an elastic member, the spaces from the back of the speakers 29 and 30 of one divided peripheral edge 23 to the inside. The end wall member 24 and the connecting member 38 can prevent the emitted sound from propagating into and interfering with another divided peripheral edge 23 adjacent to the divided peripheral edge 23.

  Further, when the speakers 29 and 30 vibrate, the divided peripheral edge 23 also vibrates, but this vibration is suppressed by being absorbed by the vibration absorbing members 23D and 23E and transmitted to the ceiling 7 and the walls 3 (4, 5, 6) and the like. Is done. As a result, sound leaking to the outside or other rooms via the ceiling 7 or the walls 3 (4, 5, 6) is reduced.

  Moreover, the division | segmentation surrounding edge 23 can be formed by extrusion-molding ABS resin etc., The length can also be set arbitrarily. Moreover, it is only necessary to provide one divided peripheral edge 23 used as a speaker box with respect to one wall, or two or more. For example, in the case of two or more, each may correspond to two of the stereo left channel and the stereo right channel, and may be used as one channel connected in series (or in parallel). Further, the divided peripheral edge 23 not used as a speaker box is connected to another divided peripheral edge 23 via a connecting member 38 without providing a mounting hole. Further, the divided peripheral edge 23 at the end is arbitrarily formed for adjusting the length of the peripheral edge 20 provided along one wall.

  Further, since the wiring 42 is wired to the wiring grooves 37 and 37 of the adjacent divided peripheral edges 23 and 23 via the connecting wiring portion 41 c of the connecting member 38, the wiring grooves of the adjacent divided peripheral edges 23 and 23 are arranged. It is possible to easily arrange the wiring 42 to 37 and 37. When the connecting wiring portion 41c has a cylindrical shape as shown in the figure, it is possible to reliably prevent the wiring 42 disposed in the wiring grooves 37, 37 from coming off.

  Moreover, since the front side engaging projection 41 of the wiring groove 37 and the connecting member 38 is covered with the pre-division cover 22a, the indoor aesthetic appearance is not impaired.

  Moreover, when the fitting protrusion 40 is attached to the end of the divided peripheral edge 23 via the end wall member 24 as shown in FIG. 10B, the contact plate 40 of the front engagement protrusion 41 as shown in FIG. 10C. Is in contact with the speaker mounting plate portion 23c, the upper end portion of the front engaging projection 41 is locked in the end of the locking groove 36c of the divided peripheral edge 23, and the connecting wiring portion 41c of the front engaging projection 41 is Since it is fitted to the end of the wiring groove 37 of the divided peripheral edge 23, the end of the divided peripheral edge 23 is sandwiched between the fitting protrusion 40 and the front engaging protrusion 41 of the connecting member 38. . As a result, even if an external force in a direction intersecting with the longitudinal direction of the dividing peripheral edge 23 acts on the connecting member 38, the connecting member 38 can be reliably prevented from coming off from the end of the dividing peripheral edge 23.

Further, the wiring 42 can be connected to the speakers 29 and 30 from the front side to the speaker connection terminals 32 and 33 of the terminal 31b on the room (building space side) 1 side of each divided peripheral edge (speaker box) 23. 42 can be easily connected to the speakers 29 and 30.
(Modification)

  Furthermore, the fitting protrusion 40, the end wall member 24, the end wall member 24, and the end portion of the divided peripheral edge 23 can be bonded and fixed.

  As described above, the speaker system according to the embodiment of the present invention is arranged along the speakers (29, 30) and the corners (ceiling side corners 16 to 19) of the space in the building (room 1). A cylinder (divided peripheral edge 23) formed by dividing a building material main body (surrounding edge main body 21) into a plurality of parts and a connecting portion that connects adjacent ends of the plurality of cylindrical bodies (divided peripheral edges 23). And a member. In addition, in the speaker system, at least one of the plurality of cylinders (division surrounding edge 23) is provided with a speaker mounting plate portion 23c facing the space in the building (room 1), and the speaker mounting plate portion 23c is provided with the speaker. Mounting holes (26 to 27) are formed, and the speaker frame is mounted to the side edge of the speaker mounting plate part 23c on the mounting hole (26 to 27) side, and the speaker mounting plate part 23c in the building. An air-permeable front cover (pre-division cover 22a) that covers the space (living room 1) side surface is provided.

  According to this configuration, the speaker (29, 30) is attached to the space in the building (speaker mounting plate portion 23c facing the living room 19) of the cylindrical body (divided peripheral edge 23) constituting the building material main body (surrounding edge main body 21), Since the surface facing the building space (room 1) of the speaker mounting plate portion 23c is covered with the front cover (pre-division cover 22a), the cylindrical body (division surrounding edge 23) to which the speakers (29, 30) are attached is the building. It functions as a part of the building material (around edge main body 21) As a result, it is possible to prevent the aesthetics of the room from being damaged by the speakers (29, 30).
