  The preferred embodiments of the present invention will be described with reference to FIGS.

  The implantable device of the embodiment is provided with an electrical component or an electronic component on one side of a base member. Specifically, a ceiling board (hereinafter simply referred to as a board) so that the main body is disposed on the back of the ceiling. ) Embedded in the ceiling speaker device 50. Hereinafter, the ceiling-embedded speaker device 50 is simply referred to as a speaker device 50. Further, the side opposite to the ceiling side with respect to the board is also referred to as an indoor space side for convenience.

  1 and 2 are a side view and a plan view of the speaker device 50, and FIG. 2 is a view of the speaker device 50 of FIG. 1 as viewed from above.

In FIG. 1, the speaker device 50 includes a base member 101 and a substantially truncated cone speaker unit 102 attached to one surface side of the base member 101.
In addition, the base member 101 is formed with a step-down transformer circuit housing portion 103 that protrudes to the same side as the speaker unit 102 attached.
The step-down transformer circuit storage unit 103 stores electrical components such as a circuit board 103a on which electronic components are mounted, a step-down transformer 103b, and a terminal block 103c in its internal space.
The base member 101 is formed in a substantially rectangular shape. Specifically, it is formed in a flat, substantially rectangular parallelepiped shape having a predetermined thickness t1 from a resin material.
The thickness t1 is set so that the base member 101 has a strength that can safely support the relatively heavy step-down transformer 103b.

In FIG. 2, through holes 201 to 204 are provided at four corners of the base member 101.
The through holes 201 to 204 are holes provided so as to be used when the speaker device 50 is fixed with screws.

As apparent from FIGS. 1 and 2, the speaker unit 102 and the step-down transformer circuit housing portion are arranged side by side on the center line CL <b> 1 along the longitudinal direction of the base member 101.
In FIG. 2, the speaker unit 102 is generally circular, and the center CLsp is disposed at a distance Lsp from one short side 101 s of the base member 101.

The base member 101 has flanges 403a and 403b whose wall thickness is thinner than t1 at both corners on the short side 101s side.
Specifically, step portions 1a and 1b having a predetermined angle α with respect to the short side 101s are provided at both corners on the short side 101s side, and the outsides of the step portions 1a and 1b are thick. It becomes the flange parts 403a and 403b of t2.
In this embodiment, since α = 45 °, the flange portions 403a and 403b are substantially right-angled triangular regions in FIG. 2 which is a plan view.
A plurality of triangular ribs 22 (three each in the embodiment) are formed between the stepped portions 1a, 1b and the flange portions 403a, 403b, and the bending strength of the flange portions 403a, 403b is ensured. .

3 is a perspective view showing only the base member 101 when the speaker device 50 is viewed obliquely from above the left hand in FIG.
In FIG. 3, for easy understanding, the collar portions 403a and 403b are hatched.

As can be seen from FIG. 3, since the base member 101 emits the sound output from the speaker unit 102 to the outside, the sound emitting hole portion 2 and the plurality of openings 101p around the sound emitting hole portion 2 are generally formed as a whole. A circular opening is provided.
Four bosses 401a to 401d are erected around the opening 101p, and the speaker unit 102 is screwed to the bosses 401a to 401d.

  4 is a perspective view showing only the base member 101 when the speaker device 50 is viewed from the diagonally lower left side on the opposite side of the paper surface in FIG.

As is clear from FIG. 4, the base member 101 has thin portions 301 a and 301 b whose thickness is thinner than t <b> 1 in portions along the long sides 101 ta and 101 tb. In other words, the thin-walled portions 301a and 301b are formed so as to face each other at an intermediate portion between the long sides 101ta and 101tb.
More specifically, the thin portions 301a and 301b are formed in a region on the long side 101 side between the sound emitting hole portion 2 and the step-down transformer circuit housing portion 103, and are surfaces on which the speaker unit 102 is attached to the base member 101. The surface on the opposite side is formed to have a thickness t3 (see FIG. 1). Here, t3 <t1.
In FIG. 4, the thin portions 301 a and 301 b are hatched for easy understanding.
Ribs 23 are formed in the thin portions 301a and 301b, respectively, in order to ensure bending rigidity in the longitudinal direction of the base member.

The speaker device 50 described above is connected to, for example, a voice transmission device (not shown) of the in-house broadcasting system via a transmission cable (not shown), and BGM sent from the voice transmission device, various general announcements, etc. Converts audio signals from normal broadcasts and emergency broadcasts during disasters into audio and outputs them.
This audio signal is transmitted by a high impedance method in order to suppress transmission loss in the transmission cable. Therefore, the audio signal is input to the speaker unit 102 via the step-down transformer 103b.
The step-down transformer 103b is mounted on the circuit board 103a, and a speaker cable and a transmission cable connecting the speaker unit 102 and the circuit board 103a are connected to the terminal block 103c.

Next, a state where the above-described speaker device 50 is attached to the back of the ceiling will be described with reference to FIG.
Fig.5 (a) is the top view which looked down from the ceiling back, and FIG.5 (b) is the side view seen from the side. In FIG. 5B, the speaker device 50 is not a cross section, and only the board 501 is shown as the S1-S1 cross section in FIG.

5A and 5B, a ceiling board 501 has a mounting hole 502 for the speaker device 50 formed therein. In this embodiment, the mounting hole 502 is circular.
Further, the diameter φ1 of the mounting hole 502 is set larger than the width D1 of the speaker device 50.
The attachment hole 502 also functions as a sound emission hole through which the output sound from the speaker unit 102 passes.

In FIG. 5B, the space SP above the board 501 is a so-called ceiling space, and an obstacle 503 exists above the space SP.
The obstacle 503 corresponds to a duct or pipe of a housing facility such as an air conditioner or a building structure material such as joist.
In the embodiment, for convenience, the upper surface 501a of the board 501 and the lower surface 503a of the obstacle 503 are shown to be parallel surfaces. The distance between the upper surface 501a of the board 501 and the lower surface 503a of the obstacle 503 is H0.
This distance H0 is the height of the space behind the ceiling.

  Next, a process of attaching (embedding) the speaker device 50 to the board 501 will be described.

  In the mounting operation of the embedded speaker device, a transmission cable is laid in the back of the ceiling from the sound transmitting device to the vicinity of the speaker mounting position, while a mounting hole 502 having a predetermined shape is formed at a predetermined position on the ceiling board 501. Keep drilling.

Although a preparatory stage of the attachment work is not shown, first, the transmission cable is pulled out from the attachment hole 502 provided in the board 501.
Next, a transmission cable is connected to the terminal block 103c.
After completing this preparation step, the speaker device 50 is then inserted obliquely from the attachment hole 502 to the ceiling back side with the step-down transformer circuit housing portion 103 side in the longitudinal direction at the top.

FIG. 6 shows a state during the insertion. The speaker device 50 is inclined so that the upper surface 101a of the base member 101 including the speaker unit 102 and the like is on the board 501 side, and is inserted into the attachment hole 502 from the short side 101s2 side. Hereinafter, this state is referred to as a first stage.
Fig.6 (a) is a side view, The schematic diagram of the arrow Y1 in this figure is FIG.6 (b). In FIG. 6B, the board 501 is shown in cross section at the diameter position of the mounting hole 502.

In FIG. 6A, the speaker device 50 is inserted in the direction of the arrow DR1. On the leading side in the insertion direction, two positions on the lower surface side of the long sides 101ta and 101tb of the base member 101 are the mounting holes of the board 501. 102 comes into contact with the edge of the upper surface 501a side of 102. Let two contact points of both be P1. The distance between the two contact points P1 is Dh1.
On the rear side in the insertion direction, since the speaker unit 102 protrudes in a substantially truncated cone shape toward the back of the ceiling, two locations on the outer surface of the speaker unit 102 are the edge of the lower surface 501b of the mounting hole 502 of the board 501. Get in touch. Let two contact points of both be P2. The distance between the two contact points P2 is Dh2.

Further, assuming that the insertion angle of the speaker device 50 is θ with respect to the upper surface 501a of the board 501, and the maximum height of the speaker device 50 from the upper surface 501a of the board 501 is H, the maximum height H depends on the degree of insertion. Change.
Specifically, the distance Dh1 between the contact points P1 is determined by the width D1 of the rectangular base member 101 inserted into the circular attachment hole 502, and is constant regardless of the degree of insertion.
On the other hand, the distance Dh2 between the contact points P2 changes according to the protruding shape of the speaker unit 102 depending on the degree of insertion.

In the speaker device 50, since the speaker unit 102 protrudes in a generally truncated cone shape as described above, the distance Dh2 increases as the degree of insertion proceeds and reaches a maximum at a position corresponding to the maximum diameter of the speaker unit 102. And then decreases.
Further, the distance Dh2 between the contact points in the attachment hole 502 corresponds to the length of the string Ph when the opening shape of the hole is regarded as a circle, and the contact position moves with the degree of insertion.
On the other hand, along with the insertion, the insertion angle θ becomes maximum when the distance Dh2 is maximum because the distance Dh1 is constant.

In the speaker device 50, the contact point P1 of the base member 101 is located in the region where the thin portions 301a and 301b are formed, at least at the insertion position where the distance Dh2 is maximum.
Accordingly, the portion of the base member 101 that contacts at the contact point P1 is closer to the upper surface 101a side (ceiling back side) where the speaker unit 102 is provided than when the thickness t1 where the thin portions 301a and 301b are not formed is constant. I will stop by.
Therefore, the insertion angle θ with respect to the board 501 is reduced by the amount of thinning by the thin portions 301a and 301b, and the height H0 of the space on the upper surface 501a side of the board 501 required for embedding the speaker device 50 is reduced. be able to.
In other words, it can be attached to the back of the ceiling where the space height H0 is small (low).
Further, even if the base member 101 and the board 501 do not come into contact with each other, the edge on the upper surface 501a side of the mounting hole 502 of the board 501 is entered into the space where the thin portions 301a and 301b are formed, The insertion angle θ is reduced by the amount of entry, and the space can be attached to the ceiling with a small (low) height H0.

FIG. 7 is a schematic diagram for explaining that the insertion angle θ can be reduced.
The speaker device 50 having the thin portions 301a and 301b is indicated by a solid line, and the speaker device 150 having no thin portions 301a and 301b is indicated by a broken line.
The board 501 is shown as a cross section in the diameter of the mounting hole 502.

As shown in FIG. 7, it can be seen that by providing the thin portions 301a and 301b, the insertion angle θ in the speaker device 50 is θ1, which is smaller than the insertion angle θ11 in the speaker device 150.
Therefore, the maximum protrusion height H from the upper surface 501a of the board 501 in the speaker device 50 is H1, which is smaller than the maximum protrusion height H11 in the speaker device 150.

  Here, in order to more smoothly insert the speaker device 50, the wall surfaces 301a1 and 301b1 of the thin wall portions 301a and 301b that are in contact with the attachment hole 502 at the contact point P1 are shown in FIG. 7 (see also FIG. 4). It is preferable to use an inclined surface.

The operation of inserting the entire speaker device 50 into the back of the ceiling after the first step in the embedding operation is referred to as a second step.
The second stage shows a state in which the contact point P <b> 2 on the speaker device 50 side has moved from the speaker unit 102 to the base member 101 in the speaker device 50.

  FIG. 8 is a perspective view of the second stage speaker device 50 as seen from the back of the ceiling.

FIG. 9 is a schematic diagram for explaining that the insertion angle θ can be reduced.
In FIG. 9, the speaker device 50 having the flange portions 403a and 403b is indicated by a solid line, and the speaker device 150 not having the flange portions 403a and 403b is indicated by a broken line. The board 501 is shown as a cross section in the diameter of the mounting hole 502.

The contact point P2 is located on the upper surface side of the flange portions 403a and 403b at the long sides 101ta and 101tb.
Therefore, the portion of the base member 101 that contacts at the contact point P2 is the lower surface 101bt side (indoor space side) where the speaker unit 102 is not formed compared to the case where the wall thickness t1 where the flange portions 403a and 403b are not formed is constant. )
Therefore, the insertion angle θ with respect to the board 501 is reduced by the thickness of the flange portions 403a and 403b, and the height H0 of the space on the upper surface 501a side of the board 501 required for embedding the speaker device 50 is reduced. be able to.
In other words, it can be attached to the back of the ceiling where the space height H0 is small (low).
Even if the base member 101 and the board 501 do not contact each other, the edge on the lower surface 501b side of the mounting hole 502 of the board 501 is made to enter the space that has been scooped so as to form the flanges 403a and 403b. By inserting the edge portion on the upper surface 501a side of the mounting hole 502 into the space that is formed so as to form the thin portions 301a and 301b, the insertion angle θ is reduced by an amount corresponding to the amount of each entry, and the space It can also be attached to the back of the ceiling where the height H0 is smaller (lower).

As shown in FIG. 9, it can be seen that by providing the flange portions 403a and 403b, the insertion angle θ in the speaker device 50 is θ2, which is smaller than the insertion angle θ12 in the speaker device 150.
Accordingly, the maximum protrusion height H from the upper surface 501a of the board 501 in the speaker device 50 is H2, which is smaller than the maximum protrusion height H12 in the speaker device 150.
As the base member 101 is longer, the flange portions 403a and 403b exhibit a remarkable effect of suppressing the protruding height.

  As a modification, after the contact point P1 is positioned at the thin wall portions 301a and 301b in the first stage, the contact point P1 continues until the contact point P2 is positioned at the flange parts 403a and 403b in the second stage. It is desirable to set the shape so as to be located in the thin portions 301a and 301b.

  This modification will be described with reference to FIG.

  FIG. 10 shows the speaker device 50 and the like as viewed from below the board 501 (inside the indoor space) when the contact point P2 moves from the speaker unit 102 to the base member 101 and shifts to the second stage after the first stage. It is a perspective view.

In FIG. 10, when the rear end portion of the base member 101 rotates about the contact point P <b> 1 in the direction of the arrow DR <b> 2, the surfaces on the ceiling back side of the flange portions 403 a and 403 b come into contact with the edge portion of the attachment hole 502.
Thereby, the amount of suppression of the height of the ceiling space that can be suppressed when the contact point P1 is positioned in the thin portions 301a and 301b, and the height of the ceiling space that can be suppressed when the contact point P2 is positioned in the flange portions 403a and 403b. Since the amount of suppression is added, it is most desirable.

FIG. 11 is a schematic diagram for explaining that the insertion angle θ can be made smaller by having the thin portions 301a and 301b and the flange portions 403a and 403b.
The speaker device 50 having the thin portions 301a and 301b and the flange portions 403a and 403b is indicated by a solid line, and the speaker device 150 not having the thin portions 301a and 301b and the flange portions 403a and 403b is indicated by a broken line. The board 501 is shown as a cross section in the diameter of the mounting hole 502.

As shown in FIG. 11, by providing the thin portions 301a and 301b and the flange portions 403a and 403b, the insertion angle θ3 in the speaker device 50 may be smaller than the insertion angle θ13 in the speaker device 150. Recognize.
Therefore, the maximum protrusion height H3 from the upper surface 501a of the board 501 in the speaker device 50 is smaller than the maximum protrusion height H13 in the speaker device 150.

When the speaker device 50 is further inserted in the DR1 direction from the position shown in FIG. 11, the flanges 403a and 403b of the base member 101 enter the mounting hole 502, and the contact point P2 disappears.
As a result, the base member 101 is completely housed on the back side of the ceiling, and then moved back on the board 501 in a direction opposite to the insertion direction so that the speaker unit 102 is fixed at a predetermined position facing the mounting hole 501. . This state is shown in FIG.

  The board 501 of the speaker device 50 is fixed using a spring member (not shown), one end of which is locked to a speaker grill (not shown), and the other end is locked to the speaker device 50, and the spring of the spring member is fixed. The board 501 is sandwiched between the speaker device 50 and the speaker grill by force.

  As described above, the speaker device 50 is provided with the thin wall portions 301a and 301b that are thinned toward the ceiling back side at the portion of the base member that contacts the edge on the ceiling back side of the mounting hole. When the device 50 is inserted into the back of the ceiling at an angle, the height of the protrusion to the back of the ceiling can be reduced.

In addition, since the base member is provided with the flange portions 403a and 403b that are thinned by facing the indoor space side edge portion of the mounting hole toward the indoor space side, the speaker device 50 is inclined to the back of the ceiling. The protrusion height to the back side of the ceiling when inserting can be reduced.
Therefore, the speaker device 50 can be attached to the ceiling even if the space height behind the ceiling is low.
Here, even if the base member 101 and the board 501 do not come into contact with each other, the edge on the lower surface 501b side of the mounting hole 502 of the board 501 enters the space that is beaten so as to form the flanges 403a and 403b.
