DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker
apparatus provided with at least a bass speaker and a treble speaker, and the purpose thereof is
to make the speaker box itself thin and to change the directivity characteristic of the housed
speaker It is to Generally speaking, the speaker box itself has been made thinner.-The force
device is simply one in which the speaker is simply housed in a flat speaker box. The directivity
characteristics of the / 2 force can not be changed, so that it is extremely inconvenient for the
user, and the performance as a speaker device is naturally limited. The present invention
overcomes the disadvantages of such prior art devices, and will be described with reference to
the drawings of the embodiments. 1, 2 and 3 show one embodiment of the speaker device
according to the present invention, in which 1 is a speaker box comprising a thin case, and is
engaged with the speaker box main body 2 so as to be able to move up and down. And the
speaker box sub-body 3. Then, the low frequency speaker 4 is accommodated in the speaker box
main body 2 and the high sound speaker 5 is accommodated in the upward direction in the
speaker box sub-body 3. In the speaker box 1, the speaker box main body 2 and the speaker box
sub-body 3 are integrated by a protective sheet 6 made of a flexible material, and-the speaker
box main body 2 and the speaker box sub-body 3 , “)“ ”“ ”“ ”“ ”“ ”“ ̶

fasteners such as screws, and the other end is It is connected by a flexible band 11 made of a
removable material inserted in the insertion hole 10 of the projecting rib 9 provided on the inner
surface of the speaker box sub-body 3. The flexible band 11 is provided with a gear portion 12 at
the other end so that the insertion state into the insertion hole 1o is maintained. Therefore, as
shown in FIGS. 4 and 5, when the speaker box sub-body 3 is raised and lowered relative to the
speaker box main body 2, the shape in the raised and lowered state is maintained. When the
speaker apparatus having such a configuration is used as a speaker apparatus for stereo, as
shown in FIG. 6, the speaker apparatus is disposed on both sides of the stereo apparatus 130
such as an amplifier, and the right speaker apparatus 14 The speaker box sub-body 3 can be
raised and lowered relative to the speaker box main body 2 in the speaker unit, and the left
speaker device 15 is located on the left side of the speaker unit 15). X 1 g 14 bodies.
The light may be configured to be able to be raised and lowered relative to the main body 2 of
the lamp. In this way, the listener 16 located in front of the center of both the left and right
speaker devices 14.15 can enjoy the acoustic effect according to the state of relief of the speaker
box sub-body 3, 3. In particular, since the directivity characteristics of the high-tone speakers 5
and 5 can be changed, the stereo effect can be sufficiently exhibited. In the above embodiment,
the desk-top type speaker device has been described, but the wall-mounted type may be a type,
and as shown in FIG. 7, the back surface of the speaker box main body 2 constituting the speaker
device The opening / closing leg 1T may be provided to form a stand type Q. Also, the flexible
band 11 may be made of a plastically deformable material such as lead whose both ends are
fixed to the inner surfaces of the speaker box main body 2 and the speaker box auxiliary body 3.
In addition, with respect to the speaker box main body 2, the speaker box sub-body 3 is pivoted
on each of the undulating self-arms Km @ -t, bK ′ ′ ′ ′ ′ ′ y @ t 1 cxe-y Ix ** 3 and the
speaker box sub-body 3. Alternatively, they may be frictionally coupled by spring biasing. As
described above, according to the present invention, the speaker box main body including the
thin case is connected to the speaker box secondary body including the thin case which can be
raised and lowered, and the main body of the speaker box is a speaker for bass Since the high
sound speaker is housed in the sub body respectively, the directivity characteristic of the high
sound speaker can be changed, and a speaker device capable of adding strength and weakness to
the sound pitch characteristic can be provided.
