An embodiment of a housing and a speaker device of the present invention will be described. In
the following drawings, an XYZ orthogonal coordinate system is displayed as necessary to clarify
the arrangement relationship of each part, but it goes without saying that the present invention is
not limited at all.
[0010]
The schematic configuration of the speaker device A will be described based on FIGS. 1 and 2.
The speaker device A has a substantially rectangular parallelepiped shape or a bar shape
elongated in the X direction, and is also called a bar type speaker. The speaker device A includes
a plurality of (six in the drawing) speaker units 1, a housing 2, a circuit board 3, and a cable 4.
[0011]
The plurality of speaker units 1 are provided to line up in the X direction. The speaker unit 1
outputs an audio based on an audio signal output from an external device (for example, an
amplifier) not shown.
[0012]
The housing 2 accommodates the speaker unit 1, the circuit board 3 and the cable 4 and is also
called a cabinet or an enclosure. The housing 2 includes a first housing member 21 and a second
housing member 22. The circuit board 3 is attached to the first housing member 21. The second
housing member 22 is provided with a plurality of (six in the drawing) speaker openings 226,
and the speaker unit 1 is attached to the speaker openings 226.
[0013]
The first housing member 21 and the second housing member 22 are combined with each other
with a high degree of sealing so as to eliminate or minimize air leakage, and a plurality of
fastening screws 23 (see FIG. 7) (See reference). The first housing member 21 and the second
01-05-2019
4
housing member 22 are manufactured by, for example, injection molding. The material of the
first housing member 21 and the second housing member 22 is a non-translucent resin. Further,
in each of the first housing member 21 and the second housing member 22, no hole capable of
looking into the inside of the housing 2 is provided. Therefore, when the first housing member
21 and the second housing member 22 are combined, the inside of the housing 2 can not be
viewed from the outside of the housing 2.
[0014]
The cable 4 electrically connects the speaker unit 1 and the circuit board 3. Although six speaker
units 1 are connected to the circuit board 3 by three cables 4 branched into two on the speaker
unit 1 side, the present invention is not limited to this. For example, six speaker units 1 may be
connected to the circuit board 3 by six cables 4 without a branch.
[0015]
As described above, the circuit board 3 is attached to the first housing member 21. Therefore,
one end of the cable 4 is fixed to the first housing member 21 via the circuit board 3. Further, as
described above, the speaker unit 1 is attached to the speaker opening 226 provided in the
second housing member 22. Thus, the other end of the cable 4 is fixed to the second housing
member 22 via the speaker unit 1.
[0016]
The cable 4 is a speaker in a state in which the first housing member 21 and the second housing
member 22 are combined in consideration of workability when the first housing member 21 and
the second housing member 22 are combined. The length necessary for connecting the unit 1
and the circuit board 3 is an extra length.
[0017]
The first housing member 21 will be described based on FIG.
The first housing member 21 is formed in a substantially
01-05-2019

L
shape when viewed from the X
direction. The first housing member 21 includes a substrate wall portion 211, a first boss wall
portion 212, a recess 213, and a plurality of first bosses 214, which are integrally formed.
[0018]
The board ¦ substrate wall part 211 comprises the surface by the side of -Y of the housing ¦
casing 2 in the state with which the 1st housing member 21 and the 2nd housing member 22
were combined. The circuit board 3 is attached to the inner surface (the surface on the + Y side)
of the substrate wall portion 211 at a substantially middle portion in the X direction. Although
keyhole-shaped small holes 217 (see FIG. 2) are provided near both ends of the substrate wall
211 in the X direction, the small holes 217 are shielded by a shielding member (not shown).
[0019]
The first boss wall portion 212 configures a surface on the −Z side of the housing 2 in a state
where the first housing member 21 and the second housing member 22 are combined. A
plurality of (17 in the drawing) first bosses 214 are provided on a first boss projecting surface
212 a which is an inner surface (a surface on the + Z side) of the first boss wall 212.
[0020]
The indented portion 213 is provided closer to the + X side than the X-direction intermediate
portion of the first housing member 21. The indented portion 213 is provided such that a portion
of the substrate wall portion 211 and a portion of the first boss wall portion 212 indent into the
inside of the housing 2.
[0021]
The first boss 214 protrudes from the first boss protruding surface 212 a in a direction (+ Z
direction) orthogonal to the first boss protruding surface 212 a. The first boss 214 is located
inside the housing 2 when the first housing member 21 and the second housing member 22 are
combined. The first boss 214 engages with the second boss 224 provided in the second housing
member 22 when the first housing member 21 and the second housing member 22 are
01-05-2019
6
combined, and a screw is provided by the fastening screw 23 It is a site to be stopped (see FIG.
7). The plurality of first bosses 214 are divided into two rows and arranged at substantially equal
intervals in the X direction. However, in place of the first boss 214, an engagement recess 215 is
provided at the position of the indented portion 213.
[0022]
The second housing member 22 will be described based on FIG. Similar to the first housing
member 21, the second housing member 22 is formed in a substantially L shape as viewed
from the X direction. The second housing member 22 includes a speaker wall 221, a second boss
wall 222, and a plurality of second bosses 224, which are integrally formed.
[0023]
The speaker wall 221 faces the substrate wall 211 in a state where the first housing member 21
and the second housing member 22 are combined, and constitutes the surface on the + Y side of
the housing 2. The speaker wall portion 221 is provided with a plurality of (six in the drawing)
speaker openings 226. The speaker unit 1 is attached to the speaker opening 226.
[0024]
The second boss wall portion 222 faces the first boss wall portion 212 in the state where the
first housing member 21 and the second housing member 22 are combined, and the surface on
the + Z side of the housing 2 is Configure. A plurality of (17 in the drawing) second bosses 224
are provided on a second boss projecting surface 222 a which is an inner surface (a surface on
the −Z side) of the second boss wall portion 222. Although mesh openings 227 are provided at
both ends of the second boss wall 222 in the X direction, the mesh openings 227 are shielded by
a shielding member (not shown).
[0025]
The second boss 224 protrudes from the second boss protruding surface 222 a in a direction
(−Z direction) orthogonal to the second boss protruding surface 222 a. The second boss 224 is
01-05-2019
7
located inside the housing 2 in a state where the first housing member 21 and the second
housing member 22 are combined. The second boss 224 is a portion engaged with the first boss
214 when the first housing member 21 and the second housing member 22 are combined, and
screwed by the fastening screw 23. The plurality of second bosses 224 are divided into two rows
corresponding to the plurality of first bosses 214 and arranged substantially at equal intervals in
the X direction. However, at a position corresponding to the above-described engagement recess
215, an engagement protrusion 225 that engages with the engagement recess 215 is provided.
The number of first bosses 214 and second bosses 224 is not particularly limited, and may be
one or plural other than seventeen. Further, the arrangement of the first boss 214 and the
second boss 224 is not particularly limited.
[0026]
The first boss 214 and the second boss 224 will be described based on FIGS. 5 to 7.
[0027]
The first boss 214 includes a first boss main body 2141 and a guide portion 2142.
The first boss main body 2141 is provided with a screw insertion hole 2143. The screw insertion
hole 2143 extends in the protruding direction (Z direction) of the first boss 214, and penetrates
from the outer surface (surface on the −Z side) of the first boss wall 212 to the tip surface of the
first boss main body 2141. The fastening screw 23 is inserted into the screw insertion hole 2143
from the outer surface of the first boss wall 212. The guide portion 2142 is provided so as to
project from the peripheral edge portion of the tip end surface of the first boss main body 2141
to the front side (+ Z side).
[0028]
The tip end surface of the first boss 214, that is, the first tip surface 214a which is the tip surface
of the guide portion 2142, is inclined with respect to the projecting direction (Z direction) of the
first boss 214. In other words, the first tip end surface 214a is inclined with respect to the first
boss protruding surface 212a. Further, a recess 2144 is provided at the tip of the first boss 214.
That is, a portion surrounded by the tip end surface of the first boss main body 2141 and the
guide portion 2142 is a recess 2144.
01-05-2019

[0029]
The second boss 224 is provided with a fastening hole 2243. The fastening hole 2243 extends
from the tip end side (−Z side) of the second boss 224 in the projecting direction (Z direction) of
the second boss 224, and the fastening screw 23 is screwed. As the fastening screw 23, for
example, a tapping screw such as a tap tight screw can be used. A female screw may be formed in
the fastening hole 2243. In addition, although the fastening hole 2243 does not penetrate the
second boss wall portion 222 to the outer surface (the surface on the + Z side), it may penetrate
this. A second front end surface 224 a which is a front end surface of the second boss 224 is
orthogonal to the projecting direction of the second boss 224.
[0030]
When the first housing member 21 and the second housing member 22 are combined, the first
boss 214 and the second boss 224 are opposed to each other in the projecting direction (Z
direction). And the tip of the second boss 224 engage with each other. That is, the tip of the
second boss 224 enters the recess 2144 of the first boss 214. At this time, the guide portion
2142 functions as a guide for positioning the second boss 224 with respect to the first boss 214
in a plane (XY plane) perpendicular to the projecting direction of the first boss 214 and the
second boss 224. .
[0031]
When the recess 2144 of the first boss 214 and the tip end of the second boss 224 engage, the
second tip surface 224 a abuts on the bottom surface 2144 a of the recess 2144, that is, the tip
surface of the first boss main body 2141. The bottom surface 2144a of the recess 2144 is
orthogonal to the direction in which the screw insertion hole 2143 extends, that is, the projecting
direction (Z direction) of the first boss 214.
[0032]
Then, in a state where the recess 2144 of the first boss 214 and the tip of the second boss 224
are engaged, the fastening screw 23 is inserted into the screw insertion hole 2143 and the
01-05-2019
9
fastening hole 2243 and the fastening screw 23 is tightened. Therefore, the second front end
surface 224 a and the bottom surface 2144 a of the recess 2144 become a fastening surface by
the fastening screw 23. The second front end surface 224 a and the bottom surface 2144 a of
the recess 2 144 are orthogonal to the axial direction (Z direction) of the fastening screw 23, so
that the fastening surface is orthogonal to the axial direction of the fastening screw 23. Thus,
unlike the present embodiment, when the surface inclined with respect to the projecting
direction of the first boss 214 is a fastening surface, that is, the fastening surface intersects
without being orthogonal to the axial direction of the fastening screw 23 Compared with the
case, the fastening force by the fastening screw 23 can be enhanced.
[0033]
Based on FIGS. 8 and 9, the first case member 21 and the second case member 22 are combined
in the case 2 of the prior art, and the first case member 21 in the case 2 of the present
embodiment. The difference between the case where the second housing member 22 is combined
with the second housing member 22 will be described.
[0034]
As shown in FIG. 8, the case 2 of the prior art is configured substantially the same as the case 2
of the present embodiment, but the first end surface 214 a of the first boss 214 is a protrusion of
the first boss 214. They differ in that they are not inclined but parallel to the direction.
[0035]
As described above, one end of the cable 4 is fixed to the first housing member 21, and the other
end of the cable 4 is fixed to the second housing member 22.
Also, the cable 4 has a length with a margin.
Therefore, when the first housing member 21 and the second housing member 22 are combined,
the space between the first boss 214 and the second boss 224 is in a state where the first boss
214 and the second boss 224 face each other. The cable 4 is easy to enter. Further, as described
above, when the first housing member 21 and the second housing member 22 are combined, the
inside of the housing 2 can not be viewed from the outside of the housing 2. Therefore, when the
operator combines the first housing member 21 and the second housing member 22, the first
boss 214 and the second boss 224 are viewed from the outside of the housing 2 while the
01-05-2019
10
worker is looking at the first boss 214 and the second boss 224. It is difficult to divert the cable
4 so that the cable 4 does not enter between the second boss 224 and the second boss 224.
Although the inside of the housing 2 can not be viewed at all from the outside of the housing 2,
there is a similar problem also in the case where the viewing is difficult.
[0036]
When the recess 2144 of the first boss 214 and the end of the second boss 224 engage with the
cable 4 entering between the first boss 214 and the second boss 224, the first boss 214 and the
second boss are engaged. The cable 4 is pinched between it and 224. In this case, a gap is
generated between the first housing member 21 and the second housing member 22, and the
degree of sealing of the housing 2 is reduced, so that air leakage may occur, and the sound
quality of the speaker device A may be reduced. is there. In addition, there is a possibility that the
pinched cable 4 may be broken. In order to avoid such pinching of the cable 4, the cable 4 is
fixed to a rib or the like provided on the first housing member 21 or the second housing member
22 with a tape or the like, or formed into a rib or the like. It is also conceivable to fix it by fitting
it in the slit. However, in such a case, the work efficiency is lowered because work to fix the cable
4 occurs, and the material cost is increased when using a tape or the like.
[0037]
On the other hand, as shown in FIG. 9, in the housing 2 of the present embodiment, the first end
surface 214 a of the first boss 214 is inclined with respect to the protruding direction of the first
boss 214. Therefore, even when the cable 4 is inserted between the first boss 214 and the
second boss 224 in a state where the first boss 214 and the second boss 224 face each other, the
recess 2144 of the first boss 214 and the When the tip of the 2 boss 224 engages, the cable 4 is
pushed by the second boss 224 and moves along the first tip surface 214 a. Thereby, the cable 4
can be discharged from between the first boss 214 and the second boss 224. Also, in this case,
no work for fixing the cable 4 occurs and no additional material such as a tape is required.
[0038]
The inclination angle of the first end surface 214a with respect to the first boss projecting
surface 212a is not particularly limited, but is preferably 30 degrees or more and 60 degrees or
less, and is 40 degrees or more and 50 degrees or less Is more preferred. If the inclination angle
01-05-2019
11
of the first front end surface 214a is 30 degrees or more, the cable 4 can be effectively
discharged from between the first boss 214 and the second boss 224. Further, if the inclination
angle of the first front end surface 214a is 60 degrees or less, the projection height of the first
boss 214 becomes low, so the mold of the first housing member 21 can be thinned, and a mold
can be used. Cost required can be reduced.
[0039]
The relationship between the direction in which the first front end surface 214a is directed and
the wiring direction D of the cable 4 will be described based on FIGS. 10 and 11. In the
circumferential direction around the protruding direction (Z direction) of the first boss 214, the
first front end surface 214a is in the wiring direction D (Y direction) of the cable 4 in the portion
closest to the first boss 214 in the cable 4. It is facing the direction (+ X direction) which crosses
to it. In this case, even if the cable 4 enters between the first boss 214 and the second boss 224
in a state where the first boss 214 and the second boss 224 face each other, the wiring direction
D of the entered cable 4 (Y direction ) Intersects the direction (+ X direction) in which the first tip
end surface 214a is directed. Therefore, the cable 4 can be effectively discharged from between
the first boss 214 and the second boss 224. The direction intersecting with the wiring direction
D of the cable 4 is a concept including not only a direction orthogonal to the wiring direction D,
that is, a direction intersecting at an angle of 90 degrees, but a direction intersecting at an
arbitrary angle.
[0040]
As described above, in the case 2 of the present embodiment, the cable 4 is accommodated
inside, and the first case member 21 and the second case member 22 are provided. The first
housing member 21 has a first boss 214 protruding from the first boss projecting surface 212 a.
The second housing member 22 has a second boss 224 projecting from the second boss
projecting surface 222a. The first boss 214 engages with the second boss 224 when the first
housing member 21 and the second housing member 22 are combined. The first end surface 214
a which is the end surface of the first boss 214 is inclined with respect to the direction in which
the first boss 214 protrudes.
[0041]
01-05-2019
12
According to this configuration, when the first housing member 21 and the second housing
member 22 are combined, the first boss 214 and the second housing member 22 provided on
the first housing member 21 are provided. It is possible to prevent the cable 4 from being
pinched between the second boss 224 and the second boss 224. Therefore, it can suppress that
the sealing degree of the housing ¦ casing 2 falls, and can suppress that the cable 4 is damaged.
[0042]
In the present embodiment, one end of the cable 4 is fixed to the first housing member 21, and
the other end of the cable 4 is fixed to the second housing member 22. This configuration is
particularly useful because the cable 4 can easily enter between the first boss 214 and the
second boss 224 when the second housing member 22 and the second housing member 22 are
combined. Further, in the present embodiment, when the first housing member 21 and the
second housing member 22 are combined, the worker looks at the first boss 214 and the second
boss 224 from the outside of the housing 2 and This configuration is particularly useful because
it is difficult to divert the cable 4 so that the cable 4 does not enter between the 1 boss 214 and
the second boss 224.
[0043]
In addition, the speaker device A of the present embodiment includes the housing 2, the cable 4
housed in the housing 2, and the speaker unit 1 housed in the housing 2.
[0044]
According to this configuration, it is possible to suppress a decrease in the degree of sealing of
the housing 2 and, therefore, it is possible to provide a speaker device A that is low in air leakage
and excellent in sound quality.
[0045]
A modification of this embodiment will be described.
In each modification, the contents similar to those of the embodiment or modification described
above will be omitted as appropriate, and differences from the embodiment or modification
described above will be mainly described.
01-05-2019
13
[0046]
The housing 2A of the first modified example will be described based on FIG.
In the housing 2 </ b> A, the first housing member 21 is provided with a peripheral side surface
protruding portion 216 protruding from the peripheral side surface of the first boss 214. The
circumferential side protrusion 216 has a continuous surface 216a continuous to the top 2145
of the first front end surface 214a, that is, the position of the first front end surface 214a with
the highest projection height with respect to the first boss projection surface 212a. . The
continuous surface 216a is inclined with respect to the projecting direction of the first boss 214,
similarly to the first tip surface 214a. That is, the continuous surface 216a is inclined with
respect to the first boss projecting surface 212a. The inclination angle of the continuous surface
216a with respect to the first boss projecting surface 212a is equal to the inclination angle of the
first end surface 214a, but is not limited to this and is smaller than the inclination angle of the
first end surface 214a. Also, it may be large.
[0047]
Based on FIG. 13 and FIG. 14, the difference between the first boss 214 of the housing 2 of the
embodiment described above and the first boss 214 of the housing 2A of the first modification
will be described.
[0048]
As shown in FIG. 13, the circumferential side protrusion 216 is not provided in the first boss 214
of the housing 2 of the above-described embodiment.
Therefore, for example, when a plurality of cables 4 are bundled and there is a groove 4a along
the length direction of the cable 4 in the cable 4, the groove 4a of the cable 4 is the first tip end
surface It may be caught on the top 2145 of 214a. In such a case, even if the cable 4 is pushed
by the second boss 224, the cable 4 may not move along the first front end surface 214a
because the cable 4 is hooked on the first front end surface 214a.

On the other hand, as shown in FIG. 14, the first boss 214 of the housing 2A of the first
modification includes the peripheral side surface protruding portion 216 having the continuous
surface 216a continuous with the top 2145 of the first front end surface 214a. As a result, the
cable 4 is prevented from being caught on the top 2145 of the first front end surface 214a.
Thereby, when the first housing member 21 and the second housing member 22 are combined, it
is more effectively suppressed that the cable 4 is sandwiched between the first boss 214 and the
second boss 224. be able to.
[0050]
The housing 2B of the second modified example will be described based on FIGS. 15 and 16. In
the housing 2 </ b> B, the second end surface 224 a which is the end surface of the second boss
224 is inclined with respect to the projecting direction of the second boss 224. Further, the
bottom surface 2144a of the recess 2144 of the first boss 214 is inclined at the same angle as
the second front end surface 224a. In the circumferential direction around the protruding
direction (Z direction) of the second boss 224, the second front end surface 224a faces the same
direction (+ X direction) as the direction (+ X direction) to which the first front end surface 214a
faces. . In addition, although the 1st housing member 21 is provided with the surrounding side
protrusion part 216, it is not necessary to provide this. Further, the bottom surface 2144a of the
recess 2144 of the first boss 214 is not limited to the configuration inclined at the same angle as
the second front end surface 224a, and for example, is orthogonal to the projecting direction of
the first boss 214 It is also good.
[0051]
According to this configuration, the angle θ that the second front end surface 224a makes with
the first front end surface 214a is 90 degrees as compared to the case where the second front
end surface 224a is parallel to the second boss protruding surface 222a. Get close. Therefore, the
force by which the cable 4 is pushed in the direction along the first end surface 214 a by the
second boss 224 becomes strong, and the cable 4 is effectively discharged from between the first
boss 214 and the second boss 224. Can.

A housing 2C of a third modification will be described based on FIGS. 17 and 18. In the housing
2 </ b> C, a second front end surface 224 a which is a front end surface of the second boss 224
is inclined with respect to the protruding direction of the second boss 224. In the circumferential
direction around the protruding direction (Z direction) of the second boss 224, the second tip
surface 224a intersects the direction (+ Y direction) with the direction (+ X direction) to which
the first tip surface 214a faces. I'm facing. In addition, although the 1st housing member 21 is
provided with the surrounding side protrusion part 216, it is not necessary to provide this.
[0053]
According to this configuration, when the wiring direction D of the cable 4 which has entered
between the first boss 214 and the second boss 224 is the Y direction (in FIG. 18, the cable 4 in
this case has a black circle. Since the first end surface 214a faces the direction (+ X direction)
intersecting with the wiring direction D, the cable 4 is effectively discharged from between the
first boss 214 and the second boss 224. can do. When the wiring direction D of the cable 4
which has entered between the first boss 214 and the second boss 224 is the X direction (in FIG.
18, the cable 4 in this case is indicated by a thick two-dot chain line). Since the second front end
surface 224a faces the direction (+ Y direction) intersecting with the wiring direction D, the cable
4 can be effectively made from between the first boss 214 and the second boss 224 also in this
case. Can be discharged. Thus, regardless of the wiring direction D of the cable 4 which has
entered between the first boss 214 and the second boss 224, the cable 4 can be effectively
transmitted from between the first boss 214 and the second boss 224. It can be discharged. The
direction intersecting with the wiring direction D of the cable 4 is a concept including not only a
direction orthogonal to the wiring direction D, that is, a direction intersecting at an angle of 90
degrees, but a direction intersecting at an arbitrary angle.
[0054]
A housing 2D of the fourth modified example will be described based on FIG. In the housing 2D, a
fastening hole 2146 is provided in the first boss 214, and a screw insertion hole 2246 is
provided in the second boss 224. As described above, it is not particularly limited which of the
first boss 214 and the second boss 224 the screw insertion holes 2143 and 2246 are provided
and in which the fastening holes 2243 and 2146 are provided.

Subsequently, other modified examples of the housing 2 will be described. Although the housing
2 is formed of two members of the first housing member 21 and the second housing member 22,
the present invention is not limited to this, and the first housing member 21 and the second
housing may be other members. It may be a configuration comprising a total of three or more
members including the members.
[0056]
The first boss 214 may be bent halfway. In this case, the projecting direction of the first boss
214 means the direction extending from the bent portion to the tip side. For example, when the
first boss 214 protrudes in the X direction from a plane parallel to the Z direction and is bent in
the Z direction halfway, the protruding direction of the first boss 214 is a direction extending
from the bent portion to the tip side That is, it becomes the Z direction. Similarly, the second boss
224 may be bent halfway. Also in this case, the projecting direction of the second boss 224
means the direction extending from the bent part to the tip side.
[0057]
The shapes of the first housing member 21 and the second housing member 22 are not limited
to the substantially L shape. Further, the speaker device A is not limited to the bar type, and
may be of any type and shape. The number of the speaker units 1 accommodated in the housing
2 is not particularly limited, and may be one or plural other than six.
