DETAILED DESCRIPTION OF THE INVENTION The present invention listens in the best condition,
effectively directing the speakers to the listener, with two or four speaker boxes placed in the
room for two channels and four channels. It aims to provide a speaker box that can In the
conventional speaker box for four channels, for example, as shown in FIG. 1, since the speaker
box 1 is a cube, it is disposed at the four corners of the room 2 in parallel with the wall surface.
For the listener located at the center, as indicated by the arrow in FIG. (1), the sound from the
speaker is deviated, and the level is lowered particularly in the case of high directivity of high
sound. This invention eliminates the drawbacks of such a conventional speaker box, and allows
the speaker to be freely oriented toward the listener at any position in the room. Hereinafter, the
embodiment V shown in FIGS. 2 to 4 will be described. FIG. 16 is a cross-sectional view of the
speaker box, and the speaker 5 is attached to the inside of the hemispherical box 4 with the −
side being biased, and further, in the back machine 6 of the hemispherical box 4, FIG. As shown
in FIG. 1, a number of attachments are provided with holes 7. 8 is a decorative cover such as
punch metal. The speaker box configured in this way is attached to the wall surfaces at the four
corners of the room 2 as shown in FIG. 2 for example, and the attachment is made by selecting
the holes 7 as shown by the arrows in the figure. Since the direction can be directed to the
listener, it is possible to listen to the listener in the best condition without lowering the level,
even at a highly directional altitude, particularly 2). In addition, not only the wall surface but also
the attachment, such as a ceiling and a tabletop, can be arranged freely, and there is also an
advantage that it can be easily attached. Furthermore, since this speaker box is mounted with the
speaker biased to one side in the spherical box, a large number of mountings of the back plate
can be selected depending on the wall position of the speaker box to properly position the
speaker. There is also an advantage that it can be disposed at a free angle, such as downward,
upward. As described above, the present invention provides the speaker box with the speaker
mounted on one side in the hemispherical box with a plurality of mountings provided on the
back plate of the hemispherical box. When arranging a plurality of these speaker boxes indoors
etc., since the speakers can be effectively directed to the listener, it is possible to listen in the best
condition (3). is there
