Further, the front panels 31 to 35 covering the front surfaces of the cabinets 11 to 15 are also changed in length corresponding to the lengths of the cabinets 11 to 15, so that the first end fixing member 51 at the left end is changed to the second end at the right end. The fixing member 52 can be designed to substantially cover the front side of the speaker system 10. Accordingly, the speaker system 10 covers the ceiling-side corner formed by the ceiling 1 and the wall surface 2 almost without any gap, and thus functions as a peripheral edge that improves the indoor aesthetics.

  Here, a preferred method of attaching the speaker system 10 along the ceiling-side entry corner formed by the ceiling 1 and the wall surface 2 will be described. An operator who installs the speaker system 10 first arranges the first terminal fixing member 51 so that the end thereof is very close to the left wall surface 3, and is screwed to the ceiling 1 and the wall surface 2 with a fixing screw 50. The operator can insert the tip of the driver into the internal space 51f of the first terminal fixing member 51 and allow the fixing screw 50 to pass through the fixing screw hole 51g and be screwed to the wall surface 2. Next, the operator fits the fitting protrusion 51a of the first terminal fixing member 51 screwed to the wall surface 2 and the left end portion of the cabinet 14, and then the right end of the cabinet 15 and the connection member 43 ( (Not shown) The second fitting protrusion 43 d is fitted, and the connecting member 43 is screwed to the ceiling 1 and the wall surface 2 with the fixing screw 50. Thus, the first cabinet 14 constituting the speaker system 10 can be easily attached to the wall surface close to the left wall surface 3.

  Thereafter, the operator fits the first fitting protrusion 43b (not shown) of the connecting member 43 screwed to the wall surface 2 and the left end portion of the next cabinet 12, and further the second fitting of the connecting member 41. The protrusion 41 d is fitted to the right end of the cabinet 12, and the connecting member 41 is screwed to the ceiling 1 and the wall surface 2 with the fixing screw 50. After connecting the cabinet 12 and the connecting member 41 in this manner, the operator connects the cabinet 11 and the connecting member 42, the cabinet 13 and the connecting member 44, and the cabinet 15 in the same operation. Finally, the operator fits the right end portion of the cabinet 15 and the fitting protrusion 52b of the second terminal fixing member 52, and screws the second terminal fixing member 52 to the ceiling 1 and the wall surface 2 with the fixing screw 50. To wear. In order to fit the second end fixing member 52 to the right end of the cabinet 15 and screw it to the ceiling 1 and the wall surface 2, the distance W between the end of the second end fixing member 52 and the right wall surface 4 is The height Y of the fitting protrusion 52b of the second terminal fixing member 52 may be slightly larger. The second terminal fixing member 52 can be inserted into the gap between the right end portion of the cabinet 15 and the right wall surface 4 and can be fitted to the right end portion of the cabinet 15. If the distance W is smaller than the entire length of the ceiling-side corner, the speaker system 10 covers the ceiling-side corner formed by the ceiling 1 and the wall surface 2 almost without any gap. By configuring the speaker system 10 so that such a mounting method is possible, an operator can easily mount the speaker system 10 along a corner of a building space in a short working time without damaging the indoor aesthetics. Can do.

  In the speaker system 10 configured by the above mounting method, each cabinet 11 to 15 includes a wiring groove portion defined by the lower flange 11b, and each connection member 41 to 44 communicates with the wiring groove portion. (Or a wiring notch), and the first terminal fixing member 51 and the second terminal fixing member 52 also have a wiring hole (or wiring notch) communicating with the wiring groove. The wiring groove and the wiring hole that communicate with each other can accommodate the wiring 20 that transmits an audio signal to the terminal of each speaker. Moreover, the wiring groove part and wiring hole of the speaker system 10 are covered with the front panels 31 to 35 and are not exposed. The front panels 31 to 35 are attached to the front sides of the cabinets 11 to 15, respectively, and are formed in a shape that covers the connecting members 41 to 44, the first terminal fixing member 51, and the second terminal fixing member 52. The front panels 31 to 35 covering the ceiling-side corners formed by the ceiling 1 and the wall surface 2 with almost no gap are exposed to the viewer in the living room. Therefore, in the speaker system 10, not only the cabinet and the connecting member, but also the wiring 20 is not exposed, and the indoor aesthetics can be maintained.

  When the speaker system 10 is mounted along the corners of the ceiling 1 and the wall surface 2, the contact connection walls of the connection members 41 to 44 contact the ceiling 1 and the wall surface 2, and the first terminal fixing member 51 and Since the abutment fixing wall of the second terminal fixing member 52 abuts against the ceiling 1 and the wall surface 2 and the cabinets 11 to 15 do not directly abut against the ceiling 1 and the wall surface 2, vibrations generated by the speakers 21 to 22 are not generated. It can be made difficult to be transmitted to the wall. When a vibration absorbing layer made of an elastic material is further provided on the contact connecting walls of the connecting members 41 to 44 and the contact fixing walls of the first terminal fixing member 51 and the second terminal fixing member 52, the speakers 21 to The vibration generated at 22 can be made difficult to be transmitted to the ceiling 1 and the wall surface 2.

  8A and 8B are diagrams for explaining another connecting member 41 further provided with vibration absorbing layers 41i and 41j made of an elastic material. FIG. 8A is a front view, FIG. FIG. 8C is a sectional view taken along the line DD ′ viewed from the ceiling 1 side.
