The two tops on the lower side are located substantially on the lower sides of the left and right side ceilings, respectively, and are arranged diagonally downward in the room to form the corners of the side ceilings. Each of them is formed in a triangular shape (that is, the front surface of the speaker device in FIG. 11 is an inverted triangular shape, whereas in the present invention it is a non-inverted triangular shape.), So that the continuity between the side ceiling and the front surface of the speaker device is continuous. Is improved, which reduces discontinuous unevenness in the sound field and can reduce adverse effects on acoustic characteristics.

Also, since the inclined surface is a non-inverted triangular shape, the bottom surface having one side as the bottom surface can be configured as the corner portion of the wall portion (No. 11).
In the case of the figure, since one vertex is located on the lower side, the bottom surface cannot be configured. ), A lighting device or the like can be embedded in the bottom surface.

In addition, since the emission surface of the speaker faces obliquely downward, the sound field reproducibility is excellent. Further, since the cabinet is arranged by utilizing the back space formed by the side ceiling,
Compared to the case without a side ceiling as shown in Fig. 11, the depth of the cabinet can be increased and a large-diameter speaker with a large magnet can be installed. In addition, since the volume of the cabinet can be made large, the extension of the bass range can be improved. Also, since there is a side ceiling, the unevenness of the room itself is reduced.
