[0016]
<Structure of Speaker Device 1> The speaker device 1 includes a pair of speaker boxes 10A and
10B, and a coupling mechanism 30 (FIGS. 7 and 8) for coupling the reference surfaces 11A and
11B of the speaker boxes 10A and 10B. In the following description, since the speaker boxes 10A
and 10B have substantially the same shape, when it is necessary to identify and explain, the
speaker boxes 10A and 10B and common components have suffixes A and B are added and
10-05-2019

described, and subscripts A and B are not added if it is not particularly necessary to distinguish.
[0017]
Here, FIG. 5 showing the speaker device 1 in the horizontal state, FIG. 6 showing the speaker
device in the vertical state, and FIGS. 7 showing the gist of the speaker device 1 in an enlarged
manner The configuration of the speaker device 1 will be described with reference to FIG. 8 and
FIGS. 7 and 8 are drawn with a gap formed for the convenience of illustration, but the actual gap
is a dimension which can not be illustrated. The speaker box 10 is formed in a hollow rectangular
solid shape using resin as a material. Of the bottom surface and the flat surface which are
separated in the longitudinal direction, the flat surface to be coupled to another speaker box 10
is the matching surface 11, and a coupling groove 31 (to-be-connected portion) (FIG. 6 to FIG. 8)
Be done. On the other hand, on the bottom surface of the speaker box 10, a projecting portion 14
which is larger than the reference surface 11 and which protrudes in one direction (Z direction in
the horizontal installation state of FIG. 1; X direction in the vertical installation state of FIG. 2)
The leg 13 which has is provided.
[0018]
Further, a main speaker 21 is provided on one side surface extending in the longitudinal
direction adjacent to the reference surface 11 of the speaker box 10, and a saran net 20 is
provided on the one side surface so as to cover the main speaker 21. Moreover, the woofer 22 is
provided in the other side adjacent to one side. This arrangement relationship is clear when
looking at the six views of FIG. 3 and the six views of FIG. When the speaker device 1 is used in a
horizontally placed state, as shown in FIG. 7, the tips of the protruding portions 14A and 14B of
the legs 13A and 13B are disposed in contact with the floor surface F. For this reason, a space S
is formed between the other side surface and the floor surface F. Since the space S floats the
woofer 22A, 22B from the floor surface F, the vibration of the woofer 22A, 22B is not restricted,
so the generated sound is not suppressed. Further, as shown in FIG. 1, the speaker device 1 can
be brought closer to the liquid crystal television 100 by inserting a portion of the leg of the liquid
crystal television 100 that extends to the floor surface F into the space S. Both can be integrated.
[0019]
Next, the coupling mechanism 30 will be described. The coupling mechanism 30 couples and
10-05-2019
6
separates the speaker boxes 10A and 10B. The coupling mechanism 30 includes coupling
grooves 31A and 31B to be coupled portions, and a coupling plate 35 to be coupled to the
coupling grooves 31A and 31B. As shown in FIG. 6, the coupling groove 31 is formed by cutting
so as to open on the back surface while leaving a part on the front side of the reference surface
11. A concave slope 32 is formed on the longitudinal groove surface extending in the Y-axis
direction among the coupling grooves 31 so that the width dimension in the X-axis direction is
narrowed toward the reference surface 11. In addition, on the bottom surface of the coupling
groove 31, an electrode 33 which is separated in the X-axis direction and partially exposed to the
outside is disposed. As shown in FIGS. 7 and 8, the electrode 33 is connected to a lead 34B
connected to the main speaker 21 and the woofer 22 and a lead 34A connected to an amplifier
(acoustic signal processing circuit) 15 formed of an electronic component. Be done. The amplifier
15 also includes a processing circuit that generates a 2.1 channel surround effect by the main
speaker 21 and the woofer 22.
[0020]
On the other hand, the side surface of the connecting plate 35 extending in the Y-axis direction is
cut in a substantially "V" shape as shown in FIG. As a result, a convex inclined surface 36 is
formed on one side surface of the coupling plate 35 so as to extend upward and downward from
the central portion in the height direction, and the longitudinal cross section becomes
substantially drum-shaped as a whole. In the state where the coupling plate 35 is inserted into
the coupling grooves 31A and 31B, as shown in FIGS. 7 and 8, since the concave inclined surface
32 and the convex inclined surface 36 are in contact, the speaker boxes 10A and 10B The
speaker box 10 is physically coupled by restricting separation.
[0021]
Further, as shown in FIGS. 9 and 10, the connecting plate 35 is provided with a plurality of
connecting members 37 made of a conductive material penetrating from the front to the back
sideways. As shown in FIG. 10, the connecting member 37 has contact portions 37U and 37D
with curved ends, and the contact portions 37U and 37D are supported in a cantilevered state.
Therefore, the contact portions 37U and 37D can be deformed in the arrow direction. The
coupling plate 35 is inserted into the coupling groove 31 while bringing the concave inclined
surface 32 and the convex inclined surface 36 into contact from the opposite direction of the
arrow shown by the two-dot chain line in FIG. Since the electrode 33 and the connection member
37 are electrically connected when the insertion is completed, the coupling mechanism 30 serves
not only the physical connection between the speaker boxes 10 but also the electric connection.

Become.
[0022]
On the other hand, when separating the speaker box 10, as shown in FIG. 6, the decorative cover
40 is inserted into the coupling groove 31 from which the coupling plate 35 is removed. The
thickness of the cover 40 is half the thickness of the connecting plate 35, and a convex inclined
surface 41 is formed on the side surface. By inserting the decorative cover 40 into the coupling
groove 31 in a state in which the speaker box 10 is separated, the electrode 33 is prevented from
being exposed to the outside.
[0023]
A switch group 16 (FIG. 6) for controlling the amplifier 15 is disposed on the side of the speaker
box 10A, and a terminal group 17 (FIG. 7) for inputting an acoustic signal from an external sound
source is disposed on the back. There is. The user operates the switch group 16 to enable
adjustment of various acoustic signal processing (for example, volume, bass, mid tone, high tone,
frequency, surround, etc.).
[0024]
<Operation and Effect of Speaker Device 1> In the speaker device 1 configured as above, the
speaker boxes 10A and 10B are combined and used horizontally, and the speaker boxes 10A and
10B are separated and spaced apart. Since there is a use mode in the case of using the speaker
boxes 10A and 10B in a state of being placed vertically, it is possible to generate different sound
effects with one speaker device. In addition, vertical and horizontal placement can be changed
depending on the size of the provided television. For example, if the width dimension of the
television is relatively shorter than the combined length dimension of the speaker boxes 10A and
10B, it is used in a horizontal orientation, and if the width dimension of the television is relatively
long, the television The speaker boxes 10A and 10B can be used vertically on the left and right of
the Furthermore, since the space S is secured between the woofer 22 and the floor surface F by
the projecting portion 14 when the speaker device 1 is used in the horizontal state, generation of
sound can be suppressed.

[0025]
Next, the process of inserting the coupling plate 35 into the coupling grooves 31A and 31B of
the coupling mechanism 30 will be described. When the reference surface 11A of the speaker
box 10A and the reference surface 11B of the speaker box 10B are combined, the shape formed
by combining the coupling groove 31A and the coupling groove 31B becomes substantially the
same as the cross sectional shape of the coupling plate 35. In this state, the coupling plate 35 is
inserted into the coupling grooves 31A and 31B so that the convex inclined surface 36 is along
the concave inclined surface 32. When the connecting plate 35 is inserted into the connecting
groove 31, the concave inclined surface 32 and the convex inclined surface 36 are in contact
with each other, so the connecting plate 35 restricts separation of the speaker box 10A from the
speaker box 10B. Then, the speaker boxes 10A and 10B are physically connected.
[0026]
On the other hand, in the state where the speaker boxes 10A and 10B are connected by the
coupling plate 35, the electrode 33 on the speaker box 10A side and the electrode 33 on the
speaker box 10B side are electrically connected by the connection member 37 of the coupling
plate 35. It will be. Therefore, when the speaker boxes 10A and 10B are connected by the
coupling plate 35, the lead wire for electrically connecting the speaker boxes 10A and 10B is
eliminated, and the back side of the speaker device 1 is cleaned to impair the appearance.
Suppress.
[0027]
In the speaker device 1, physical connection and electrical connection of the speaker boxes 10 </
b> A and 10 </ b> B can be performed in one operation process of inserting the coupling plate
35. Moreover, in the state where the speaker box 10A and the speaker box 10B are connected,
the lead wire connecting the speaker boxes 10A and 10B can be omitted. Then, since there is no
electrical resistance loss due to this lead wire (that is, the transmission distance of the acoustic
signal is shortened), the sound quality deterioration is suppressed, and the sound output from the
left and right speaker boxes 10A and 10B It becomes possible to eliminate bias.
[0028]
In the above case, the case where the coupling plate 35 is inserted in the state where the
10-05-2019
9
matching surfaces 11A and 11B of the speaker boxes 10A and 10B are combined is illustrated,
but one portion of the coupling plate 35 is coupled to the coupling groove 31A of one speaker
box 10A. After the insertion, the coupling groove 31B of the other speaker box 10B may be
inserted into the other portion of the coupling plate 35.
[0029]
On the other hand, when the speaker box 10 is separated, the decorative cover 40 is inserted
into the coupling groove 31 from which the coupling plate 35 is removed, so that the electrodes
33 are prevented from being exposed to the outside, and erroneous connection between the
electrodes 33 is realized. While preventing it and suppressing corrosion of the said electrode 33,
it hides from the exterior the joint groove 31 and the electrode 33, and suppresses impairing an
aesthetics.
[0030]
<Modification> Although the case where a pair of speaker boxes 10A and 10B were combined
and the speaker apparatus 1 was constituted was illustrated in the above-mentioned
embodiment, the present invention is not limited to this, and a case where three or more speaker
boxes are combined Of course, it may be used for
For example, although the above embodiment exemplifies the case where a 2.1 channel surround
system is configured by the pair of speaker boxes 10A and 10B, the present invention is not
limited thereto, and a center box is added to add a 3.1 channel system. It is also possible to
realize a 5.1 channel surround system by adding a surround system or a plurality of speaker
boxes.
[0031]
Also in the coupling mechanism 30, the coupling plate 35 is formed in a substantially drum
shape, and the coupling groove 31 has a shape into which the drum-shaped coupling plate 35 is
inserted, but the present invention is not limited thereto. May be any shape as long as the
speaker box can be coupled.
For example, the shape of the coupling plates 35A to 35D as shown in FIG. 11 may be used, as
10-05-2019
10
long as the convex portion of the coupling plate is covered by the concave portion of the
coupling groove. Furthermore, although the decorative cover 40 has a shape to be inserted into
the coupling groove 31, it may have a shape having a portion covering the entire check face 11
like a decorative cover 40A shown in FIG.
[0032]
In the embodiment, when the speaker device 1 is used in the horizontal position, the leg portion
13 having the projecting portion 14 is formed to form the space S between the floor surface F
and the side surface on which the woofer 22 is provided. Although the speaker box 10 is
provided, a mechanism may be provided between the leg portion 13 and the speaker box 10 so
that the protrusion dimension of the protruding portion 14 changes. Thus, when the speaker
device 1 is used in a vertically-mounted state, the dimensions of the projecting portions 14 are
equal on the left and right of the speaker box 10, whereby the stability of the speaker box 10 can
be enhanced.
[0033]
In the above embodiment, when adjusting the sound signal processing of the speaker device 1,
the user operates the switch group 16 provided on the side surface of the speaker box 10. A
sensor (e.g., an acceleration sensor, a gravity sensor, etc.) for detecting a placed / longitudinal
position may be provided, and adjustment of acoustic signal processing may be automatically
performed based on a detection signal from this sensor. In addition, the presence or absence of
the insertion of the coupling plate 35 may be electrically detected to automatically adjust the
acoustic signal processing. For example, when focusing on the sound generation direction of the
woofer 22, the woofer 22 is directed to an open space when used in the vertical position, while it
is formed between the floor surface F and in the horizontal state. It will head to the space S.
Therefore, even if the output of the woofer 22 is slightly increased, or the output ratio between
the main speaker 21 and the woofer 22 is automatically changed, etc., when the apparatus is
used in the vertical orientation rather than the horizontal orientation. Good.
