DESCRIPTION JPS51106124
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of the present invention,
FIG. 1 is a right side view, FIG. 2 is a front view, and FIG. The figure is an exploded perspective
view of the connecting neck. 1 1 63 1- 51-106 124 (2) 1 3 1 day
[Detailed description of the invention] The present proposal is the combination of #L, a new
single bit and simple cost element for the speaker box, 9 for lower production cost and better-for
the speaker box which can obtain the use result- Do. The conventional speakers are 1 in 9
appropriate positions that radiate according to the volume and range to be reproduced. Or fixed
and used. In particular, a ship, or self 1i1! In places with ll'J travel and layers, it is fixed through
the appropriate nmK platform in the ship or in the car, but it points the direction in which the
playback sound should be emitted from the self-established position, or Since there is a need to
change the radiation direction as necessary, there is a mechanism to connect the base and the
main body to each other and change the early angle of the main body at its compliance, but
simply vain the elevation angle. It is not only the lateral angle f (but not only I! The desired
angular variation was impaired by the bribery, and the father was also at risk of noise generation
in the ninth. In view of the above, the inventor of the present application sees the pointing
direction of the speaker or KR movement by the photographing even in the case where the result
of the research is attached to the ship or the self-effect * cold traveling and the place
accompanied by the photographing movement. Furthermore, a speaker box made of a speaker
capable of extending the sound environment of the playback sound while maintaining the
positioning of the one side, the female side or the side direction of the one angle freely and the
positioning of the one side can be reliably maintained. It is Therefore, the purpose of 1 * @ is to
make the mounting movement of the speaker be a single-piece, in particular the change of the
pointing direction provides a very formidable "T" lff & ff-car box, even in the case of a shakeplace. The next object of the present invention is to provide a speaker box that can be provided
easily and easily, and the next object of the present invention is to provide a robust, sound effect

good speaker box. is there. The other objects and features of the present invention can be known
by the following description. The construction of the invention will now be described in detail
with reference to the attached drawings. It is composed of a box body (1), a series ** fl (2) and a
pedestal (3) by molding of a synthetic resin material, and the box body (1) has a tree-like
connection using a bold hole (4). A front body (7) with a shaft (5) projecting downward and a
radial window (6) cut out substantially perpendicular to the screen, and a rear body (Fig. 9) are
mutually fitted in the mouth portion, and a reproduction sound lateral structure consisting of an
electrode plate, an amplification member, a lead wire, etc. is built in, and the train IIi! In the ll
group 121, a rotary shaft f11 having a screw hole (d) is provided at the lower side, and a concave
@ (121, +121 is provided on the lower surface during rolling). The left part (15) in which the
ridge (13) of Manji's ridge is carved and the bold hole (14) is provided, and the right sum part fl
'/ 1 in which the bold hole (16) is provided on the other side And the pipe set up, above-the left
of the emergency!
The vertical groove (18) & bold hole 19) is cut out in 11 of 11 parts (15), and the concave part
(201, 120+ is engraved = 9 substantially members (21) of the lll I face Kmlk 内) F) The ridges
(13) and iIl damage (1d) are attached in such a way that they fit each other, and the two or the
bit members (21) are provided with nine concave portions (20), R-plane projections
corresponding to 1201 K The end member (25) is placed on the inside 111 of the abovementioned male member (2) by the point where the +221 is expanded outward and the bold hole
and the holding piece (No. 2), (No. 2) are provided. A female, 111 member (2) 1. a female
member, in which the concave portion C 20), (20) and the spherical projection (22) are fitted
together. Through (25), the left and right neck (1151, (l) @) connect the box main body (X) @ + 5)
and hold it, and connect it with the box main body fil through bolded 1261 and butterfly screw
12'71. 4. Connect # Dg + 21 to each other, and in that part, change the angle of attack of the box
main body 1) and the angle I of the box. The pedestal portion 131 has six recessed portions (301,
+301) and a rotary shaft hole (31) for housing the spring 128), +28) and the ball (9), (29). ), (32),
the rotary shaft (11) of the dust neck portion (2) is inserted and stored in the rotary-hole (31), so
that @ # Neil 1291, (29 + JcK connection 91111 1 (2) v lower surface The rolling contact recess
(121, 112+ is fitted in), and it is rotatably connected at the rotary shaft 1111i-(b) rolling wheel
hole C3 through a washer (33) and a screw (n). The box body (1) can be configured to be able to
perform 360 lines of a series. Since the invention of the mush is based on the above-mentioned
constitution, the box body is interposed between the left and right necks of the connecting shaft,
and the angle of attack and the angle of depression can be changed very easily and smoothly by
the 9C second member and the turning member. At that time, since the concave part and the
spherical projection fit each other, they are provided on the lower surface of the head part and
on the lower surface of the connecting neck without fear of a change in the angle of the
installation location. The box body is very easy to displace in the lateral direction by 360 degrees
and is easily slipped, and even in the case of scissors etc., the direction in which the box body is
moved in a direction of 9 lines is also suitable. There is no change. Furthermore, since the front

Iti radiation window of the box body was circular and was cast approximately vertically, the
radiation direction of the reproduced sound was reliable, and by sipping the radial window in the
rear lower part of the R solution, A raw sound became Excessive echo bundle in the box body will
not cause resonance 41 '(therefore, the sound effect by the listening position may not be
impaired, and it is possible to expect generation of a good reproduction sound, and furthermore,
since the mechanism is simple) It has various practical effects such as being rich in productivity,
robust and inexpensive.
