DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker box
suitable for use in an audio system such as an electronic musical instrument stereo reproduction
apparatus, and a sound radiation direction from the speaker without changing the direction of
the 4IK speaker cabinet. (, 1 can be 15 can be a nine-tone cabinet. As shown in FIG. 1, a
conventional apparatus of this type is, for example, an electronic musical instrument l on the
stage, which is connected via a speaker cord 3.3... In order to change the direction 2 ° (1), the
tone cabinet 2 itself is moved to change its direction f, and the spread of the sound is performed.
Since each tone cabinet is randomly W-yt V, it is not aesthetically pleasing, and recommending a
5 and a very slight tone cabinet has the disadvantage of being inconvenient in handling. In order
to eliminate the above-mentioned conventional drawbacks of this invention, the baffle plate in
the tone cabinet can be made to be b1 # with seven tones so that the sound emission direction of
the speaker without the tone gear 10 vignette body 1- # It is something that can be changed.
Next, this will be detailed in detail with reference to the embodiment shown in FIG. 1 to FIG. In
each figure, the number is mainly composed of a 15 point wooden box, and mK is the upper
plate! In addition, a bottom plate 6 is provided on the lower surface, and a back plate 7 is
provided on the rear surface. The inner KFi baffle plate 8 of the main body 4 is pivotally attached
to the upper plate 5 and the lower plate 6 at 1119A and 9B, respectively, on the shaft 9A
penetrating the upper plate 5. . (2) Set the knob 10 on the stem and turn the baffle plate 18 to
the left and right to the main body 4! i51? Configure the speaker SP to the back # of this
buckle plate 8, while setting up the front of the tone cabinet and a protective net 111frq such as
1llllff KFi sara / net 5: set. In the 41st pi, 12 and 12 are pillars. The $ 1 price of this device is like
fishing, but if it is made of a baffle plate made of a hard material, it has the same buckle effect as
a conventional product, and it has a knob 0 by -1. The direction of the inner buckle plate can not
be seen from the outside because it can be covered with the external surface by Neso) U, so the
direction of the internal buckle plate can be arranged side by side in a certain direction. By
changing the direction f of the buckle plate, the direction of sound wave radiation can be directed
in any direction, and the spread of sound according to the taste can be obtained, and it is
necessary to move the heavy tone cabinet.
It is a fist thing. As described above, according to the present invention, the defensive net is
provided mainly on the front of the tone cabinet, and the buckle plate 1 is allowed to rotate in
the main subject of age in the background of this 20 (3) net. The direction of the baffle plate # is
changed from the outside of the main body of the arrangement through a sweeping member
such as a multi-chamber knob. It is possible to create a broad sound field by simply changing the
direction of the baffle plate with the knob instead of using a large tone cabinet because it can be
converted to a wide sound field, so the operation is random and the outer surface of the tone
cabinet Because the inner 10 parts of the baffle plate can not be covered by the net etc. of this,
this tone cabineso) 1 can obtain the spread of the sound even if it is installed side by side in a
fixed direction, so that a tone cabinet which is aesthetically good is obtained The practical effect
of cans is a useful invention that has a large effect. 15! In addition, it is possible to rotate by
remote control from a place where it is turned as a pivoting means of the baffle plate according
to the present invention. In this way, the operator of the spectator (user's seat) can adjust the
acoustic effect of the remnant's # 20 (4). 14. Clarification of simple faces tIl, 1! 21 is a layout
