DESCRIPTION JP2010232924
An object of the present invention is to prevent vibration of a ceiling decorative board from being
transmitted to a building frame through a mounting frame, and to effectively suppress solid
transmission to the periphery. SOLUTION: A vibrator 6 is attached to the back surface of a thin
ceiling decorative board 5 which also serves as a diaphragm disposed parallel to the ceiling
surface 1, and a lower surface portion 5c of the ceiling decorative board 5 is an interior
decorative surface. It is a ceiling material with a speaker function provided with an opening 16
for exposing the central portion of the interior decorative surface of the ceiling decorative plate 5
downward to the mounting frame 3 attached to the ceiling surface 1. The holding means for
holding the outer peripheral portion of the ceiling decorative plate 5 repel each other at
respective positions facing in the vertical direction A of the lower surface portion 5c of the outer
peripheral portion of the ceiling decorative plate 5 and the inner upper surface portion 3b of the
mounting frame 3 It consists of a pair of upper and lower magnets 7 and 8 which are made to
face each other in a facing direction. The ceiling decorative board 5 is configured to float up to a
position not in contact with the mounting frame 3 using the magnetic repulsion between the two
magnets 7 and 8. [Selected figure] Figure 1
Ceiling material with speaker function
[0001]
The present invention relates to a ceiling material having a speaker function.
[0002]
Conventionally, a speaker device is known which generates a sound by housing a diaphragm
inside a speaker housing and vibrating the diaphragm with a vibrator attached to the back

surface of the diaphragm (for example, a patent). Reference 1).
[0003]
In this type of speaker device, when the diaphragm emits a sound, the vibration is transmitted to
the air, but as a reaction, the speaker housing itself is also vibrated, so the solid propagation
phenomenon is transmitted to the vibration to which this vibration is fixed. It is a problem.
In particular, in the attachment structure where the speaker device is attached directly to the
ceiling surface, vibration is transmitted to the next room or the surrounding space by solid
propagation, and the noise due to the sound due to the vibration or resonance to the person in
the surrounding space Sometimes it makes me feel good.
Therefore, there is also a problem that the mounting structure of the speaker device becomes
complicated, for example, it becomes necessary to interpose a vibration absorbing member
between the speaker device and the ceiling surface.

the ceiling surface 1 is provided with a holding means for holding the outer peripheral portion of
the ceiling decorative plate 5 It is a ceiling material with a speaker function provided with an
opening 16 for exposing the central part of the interior decorative surface of 5 downward, and
the holding means includes the lower surface 5c of the outer peripheral portion of the ceiling
decorative plate 5 and the attachment A pair of upper and lower magnets 7 and 8 are attached to
respective positions facing in the vertical direction A with the inner upper surface portion 3b of
the frame 3 so as to be opposed to each other in a repulsion direction.
It is characterized in that the ceiling decorative board 5 is floated to a position not in contact with
the mounting frame 3 by utilizing the magnetic repulsion between the two magnets 7 and 8.
[0007]
With such a configuration, in addition to the original function as the ceiling building material, the
speaker function can be added by the ceiling decorative board 5 with the vibrator 6, and
furthermore, the pair of magnets 7, 8 repel each other The ceiling decorative board 5 can be
floated up inside the mounting frame 3 by the simple holding structure attached in the facing
direction, whereby the vibration of the mounting frame 3 itself can be suppressed, and the
vibration of the ceiling decorative board 5 is the mounting frame It becomes possible to suppress
propagation to the building frame through 3.
[0008]
Further, it is preferable to interpose a cushioning member 15 having a cushioning property in
the gap 9 in the lateral direction B between the outer peripheral end face 5b of the ceiling
decorative plate 5 and the inner peripheral surface 3a of the mounting frame 3 opposite thereto.
In this case, since the buffer member 15 can prevent the staggering operation of the ceiling
decorative plate 5 vibrating in the floating state in the lateral direction B, the vibration
suppressing effect of the mounting frame 3 itself can be enhanced.
[0009]
Further, the pair of left and right second magnets 10 and 11 repel each other at respective
positions facing in the lateral direction B of the outer peripheral end face 5b of the ceiling
decorative plate 5 and the inner peripheral surface 3a of the mounting frame 3 opposite thereto.

A is performed by the magnetic repulsion of the second magnets 10 and 11, The magnetic
repulsive force of the three magnets 12 and 13 can respectively suppress the stability of the
ceiling decorative plate 5 further, and the contact and friction between the ceiling decorative
plate 5 and the mounting frame 3 can be more reliably avoided.
[0010]
The present invention can suppress the vibration of the mounting frame itself by floating the
ceiling decorative plate inside the mounting frame using the magnetic repulsive force between
the pair of upper and lower magnets, and the vibration propagation to the building frame can be
suppressed. As a result, it is possible to effectively suppress the unpleasant vibration of the
neighboring room and the surrounding space and the solid propagation of the sound.
Furthermore, it is not necessary to interpose an elastic member or the like for vibration
absorption between the mounting frame and the building frame to which it is attached, and the
mounting structure can be simplified.

FIG. 1 is a side sectional view of the ceiling material 2 with a speaker function according to the
present embodiment.
Although the ceiling material 2 of this example is used as a decorative ceiling which is protruded
and attached from the ceiling surface 1, it is not limited to this, and may be embedded in a part
of the ceiling surface 1.
[0014]
The mounting frame 3 of this example is formed in a flat hollow shape, and an opening 16
surrounded by the base frame 4 is provided on the lower surface, and the opening 16 is a sound
outlet.
[0015]
A ceiling decorative plate 5 which also serves as a diaphragm is accommodated in the mounting
frame 3.
As shown in FIG. 2, the ceiling decorative board 5 is formed in a rectangular shape, and an
excitation for exciting the ceiling decorative board 5 in response to an acoustic signal from a
signal processing device (not shown) at the center of the back surface. The vessel 6 is attached.
[0016]
The pair of upper and lower magnets 7 and 8 are attached to the outer peripheral portion of the
lower surface portion 5c of the ceiling decorative plate 5 and the inner upper surface portion 3b
of the base frame 4 of the mounting frame 3 in the repulsion direction. ing.
In the example shown in FIG. 2, one magnet 7 is attached along the four sides of the lower
surface portion 5 c of the ceiling decorative plate 5, and the inner upper surface of the base
frame portion 4 located below the lower surface portion 5 c of the ceiling decorative plate 5 The
other magnet 8 is attached along the portion 3b. The pair of magnets 7 and 8 are rectangular
11-05-2019
5
rod-shaped magnets, and are attached so that the opposing surfaces have different magnetic
poles, that is, N poles or S poles, and magnetic repulsion generated between the magnets 7 and 8
Is set to such a size that it can float to a position where the ceiling decorative board 5 with the
vibrator 6 does not contact the mounting frame 3.
[0017]
Therefore, according to the ceiling material 2 of the said structure, in addition to the original
function as a ceiling building material, a speaker function can be added and the lower surface
part 5b of the ceiling decorative board 5 which serves as a diaphragm further is an interior
decoration surface. Because of this, the appearance as a decorative ceiling can also be obtained.
[0018]
Here, when arranging the ceiling decorative board 5 inside the mounting frame 3, the ceiling
decorative board 5 floats up due to the magnetic repulsive force generated between the pair of
upper and lower magnets 7 and 8 and vibrates at a position not contacting the mounting frame
3. Since the method of reproducing the rattling sound is adopted, the vibration of the mounting
frame 3 itself is suppressed, whereby the vibration of the ceiling decorative board 5 can be
suppressed from propagating to the ceiling surface 1 side through the mounting frame 3, The
effect of suppressing the unpleasant propagation of sound and vibration of the surrounding room
and surrounding space can be obtained.
Moreover, since it is not necessary to interpose the vibration absorbing rubber for suppressing
vibration propagation between the mounting frame 3 and the ceiling surface 1, the effect of
simplifying the mounting structure of the mounting frame 3 can also be obtained.
[0019]
Further, in this example, a cushioning member 15 having a cushioning property is provided in
the gap 9 in the lateral direction B between the outer peripheral end face 5b of the ceiling
decorative plate 5 and the inner peripheral surface 3a of the mounting frame 3 opposed thereto.
Here, an air bag is used as the buffer member 15. With this air cushion, it is possible to prevent
the movement of the ceiling decorative board 5 vibrating in the floating state in the lateral
direction B, and the outer peripheral end face 5b of the ceiling decorative board 5 is not in
contact with the mounting frame 3 to contact. There is an advantage that can be further

enhanced.
[0020]
FIG. 3 shows still another embodiment, in which second magnets 10 and 11 and third magnets
12 and 13 are provided in addition to the pair of upper and lower magnets 7 and 8 (first
magnets) of the embodiment of FIG. It is. In this example, the pair of left and right second
magnets 10 and 11 repel each other at respective positions facing in the lateral direction B of the
outer peripheral end face 5b of the ceiling decorative plate 5 and the inner peripheral surface 3a
of the mounting frame 3 opposite thereto. It is attached in the opposite direction to face each
other. Further, from the inner peripheral surface 3 a of the mounting frame 3, a convex rib 20 is
provided so as to protrude inward from a position above the ceiling decorative plate 5, and the
upper surface 5 a of the ceiling decorative plate 5 and the inner lower surface of the convex rib
20 A pair of upper and lower third magnets 12 and 13 are attached to the respective positions
opposite to each other in the vertical direction A with 3c in a direction in which they repel each
other. The second magnets 10 and 11 and the third magnets 12 and 13 are preferably
configured as rectangular parallelepiped rod-like magnets as the first magnets 7 and 8 are. Thus,
the swaying motion of the ceiling decorative plate 5 floating by the first magnets 7 and 8 in the
lateral direction B can be suppressed by the magnetic repulsion of the second magnets 10 and
11, and the swaying motion of the ceiling decorative plate 5 in the vertical direction A This can
be suppressed by the magnetic repulsion of the third magnets 12 and 13, thereby further
increasing the stability of the top and bottom sides and the left and right of the ceiling decorative
plate 5 and reliably avoiding contact and friction between the ceiling decorative plate 5 and the
mounting frame 3. The vibration propagation to the ceiling surface 1 side can be further
suppressed.
[0021]
Although permanent magnets are illustrated as the magnets 7, 8; 10, 11; 12, 13 in the above
embodiment, it is also possible to use electromagnets.
