DESCRIPTION JP2004080216
The present invention realizes a compact illumination notification device capable of emitting both
sound and light in a small installation space without the need to attach two audio devices and
illumination devices at two places. An illumination notification apparatus 10 includes a housing
11, a speaker unit 1 disposed in the housing 11 and having a transparent or translucent
diaphragm, and a light emitting unit 2 disposed behind the speaker unit 1. And [Effects]
Normally, lighting, music reproduction, voice guidance, etc. can be performed, and in emergency,
alarming display and alarm sounding can be performed. Since the light emitting unit 1 is
disposed behind the speaker unit 1, there is nothing to block the sound emitted from the
diaphragm, and since the empty space behind the speaker unit 1 can be effectively utilized, the
illumination notification device 10 is small. can do. [Selected figure] Figure 1
Illuminated speaker and illumination notification apparatus using the same
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an
illuminated speaker and an illumination notification apparatus using the same. This illumination
notification device is, for example, a station yard, a public facility such as a building, a production
line, a production facility, an amusement facility, an apartment, a warning / warning device in an
apartment, etc., a disaster prevention and crime prevention device, a voice guidance device, an
evacuation guidance device It can be used as a device, a device for disabled persons (deafness,
amblyopia), a notification device, a calling device, and a display device. A speaker is known in
which a light emitting element is disposed at a predetermined distance from the speaker on the
front of the speaker unit (Japanese Patent Laid-Open No. 2002-35209). If this speaker is used for
a game machine or the like, it is possible to achieve both effects by sound and effects by light in a
narrow space. [0003] However, since the substrate and the light emitting element are disposed
on the front of the speaker unit, the substrate and the light emitting element block the sound,

causing the sound pressure drop of the speaker to be reduced. become. In addition, due to the
thickness of the substrate and the light emitting element, the dimension in the thickness
direction of the speaker increases, and the installation condition becomes severe. For this reason,
there is a demand for a compact illuminated speaker that does not decrease the sound pressure
and does not increase the dimension in the thickness direction of the speaker. Further, if this
illumination type speaker is used for the illumination notification device, it is not necessary to
separately attach the audio device and the illumination device as in the prior art, and both sound
and light can be emitted in a small installation space. It is possible to realize a compact
notification device that can The illuminated speaker according to the present invention
comprises a speaker unit having a transparent or translucent diaphragm and a light emitting unit
disposed behind the speaker unit. It is possible to illuminate from the back of the speaker unit to
the front through the frame opening of the speaker unit and the diaphragm (claim 1). According
to this illuminated speaker, since the light emitting unit is disposed behind the speaker unit,
there is nothing to block the sound coming out of the diaphragm, and there is no reduction in
sound pressure. In addition, the empty space behind the speaker unit can be effectively utilized,
and the overall size can be made compact. In addition, since the reflected light beam is not used,
there is also an effect that there is no pseudo-lighting that looks as if lighted from the outside
although it is not actually lighted.
As a more specific configuration of the illuminated speaker, it is possible to fix the light source
mounting substrate to a magnet behind the speaker unit (claim 2). Since the largest structure
behind the speaker unit is a magnet, a configuration in which the light source mounting substrate
is fixed to the magnet is the most realistic. However, in addition to the magnet, the light source
mounting substrate may be fixed to the frame or the like of the speaker unit. When the
diaphragm has drip-proof performance (claim 3), it is possible to protect the light emitting unit
disposed behind the speaker unit from water. An illumination notification apparatus according to
the present invention includes a housing, a speaker unit disposed in the housing and having a
transparent or translucent diaphragm, and a light emitting unit disposed behind the speaker unit.
(Claim 4). According to this structure, by installing the casing of the illumination notification
device at a predetermined place, illumination, music reproduction, voice guidance, and the like
can be normally performed. And in the case of emergency, it is possible to perform warning light
display and alarm sounding. Since the light emitting unit is disposed behind the speaker unit,
there is no drop in sound pressure, and the empty space behind the speaker unit can be
effectively used, so the casing of the illumination notification device can be made smaller. Can.
The light source mounting substrate constituting the light emitting unit may be fixed to a magnet
behind the speaker unit, or may be fixed to the inner surface of a housing behind the speaker
unit. It is preferable that a cylindrical cover for transmitting a transparent or translucent sound is
attached at a position on the front side of the speaker unit of the housing (claim 5). By this
cylinder cover, light and sound can be diffused and transmitted while protecting the diaphragm
of the speaker, and good visibility can be ensured. In addition, the outer appearance is also
12-05-2019

improved by the cylinder cover. The cylinder cover may be slidably attached to the front and
back along the housing, and provided with slide means for sliding the cylinder cover along the
housing back and forth (claims) Item 6) The sound generation mode and the light emission mode
can be properly used depending on the state in which the cylinder cover is stored and the state in
which the cylinder cover is popped up, and the information transmission amount is increased. In
addition, in the state in which the cylinder cover is stored, a person or an object does not hit the
cylinder cover. In particular, when the tube cover is slid to a position where it protrudes from the
front surface of the housing (claim 7), since a sense of urgency can be notified, the alarm effect is
large.
When the side surface of the cylinder cover has an effect of diffusing light (claim 8), visual
recognition from the surroundings becomes easy (viewing angle becomes large) in the state of
popping out, and the alarm effect is further enhanced. The slide means may employ a solenoid, a
combination of a rack and a pinion gear, a combination of a rotary screw and a nut, a
combination of a tension spring and a locking claw, or a combination of a screw and a belt
machined on the side surface of a cylinder cover. (Claim 9). In particular, the number of parts can
be reduced by adopting a combination of a rack and a pinion gear and utilizing a waved groove
for diffusing light formed on the side surface of the cylinder cover as the rack (claim 10). .
Further, if a combination of a screw and a belt processed on the side surface of the cylinder cover
is adopted, the cylinder cover has an effect of diffusing light from the side surface of the cylinder
cover by the thread processing, which also leads to a reduction in the number of parts. (Claim
11). BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present
invention will be described in detail with reference to the attached drawings. FIG. 1 is an
exploded perspective view of the illuminated speaker according to the present invention, and FIG.
2 is a side view of the illuminated speaker. The illuminated speaker can be roughly divided into
the speaker unit 1 and the light emitting unit 2. The speaker unit 1 uses one having a
transparent or semitransparent transparent resin diaphragm 3 such as a polyester film. The
speaker unit 1 having such a transparent resin diaphragm 3 is originally developed for
waterproofing and drip-proofing purposes, but is used for the purpose of light transmission in
the present invention. The light emitting portion 2 is composed of a light source mounting
substrate 5 on which a single-color or multi-color light emitting diode (LED) 4 is mounted. The
light source mounting substrate 5 has a large hole 6 at the center, through which the speaker
magnet 7 is passed. The light source mounting substrate 5 enters the middle of the magnet 7 and
is bonded to the magnet 7 with the adhesive 8. The mounting position of the light emitting diode
4 is to face the opening of the frame 9 of the speaker unit 1. The light source mounting substrate
5 may have an incandescent lamp, a fluorescent lamp, an EL (Electro Luminescent) element, etc.,
instead of the light emitting diode. Thus, it is possible to illuminate through the transparent resin
diaphragm 3 from the back of the speaker unit 1 toward the front direction. FIG. 3 is a front view
of the illumination notification device 10 of the present invention attached to the wall 60 and a
cutaway side view showing the internal structure. FIG. 3A shows a state in which the cylinder

cover 12 is housed in the illumination notification device 10, and FIG. 3B shows a state in which
the cylinder cover 12 is projected forward by the cover drive unit 13.
The illumination notification device 10 includes the speaker unit 1 having a transparent or
semitransparent transparent resin diaphragm 3 in a cylindrical casing 11, and a light emitting
unit 2 disposed behind the speaker unit 1. Prepare. Furthermore, the illumination notification
device 10 has a transparent or translucent cylindrical cover 12 slidably attached to the front of
the speaker unit 1 along the cylindrical casing 11 in the front-rear direction. A cover drive unit
13 is provided as a slide means for sliding the cylindrical cover 12 back and forth along the
cylindrical casing 11. The light emitting unit 2 includes a light source mounting substrate 5 on
which a light emitting diode (LED) 4 is mounted, and a control board 14 provided separately
from the light source mounting substrate 5. The light source mounting substrate 5 is fixed to the
magnet 7 behind the speaker unit 1 in the same manner as described for the illuminated speaker.
The control board 14 performs control of sound and light simultaneously. The control board 14
is attached to the bottom of the cylindrical casing 11 and carries a CPU, an amplifier, and the
like. The control board 14 also has an operation unit 14 a including a volume, a mode setting
switch, a LAN connector, and the like. The operation unit 14 a is operable from the bottom outer
surface of the cylindrical casing 11 with a hand or a driver. Furthermore, a start switch 15 is
attached to the front of the cylindrical casing 11. The start switch 15 is a switch for causing the
tube cover 12 to pop out or to release the alarm manually in an alarm state. The start switch 15
is operated when performing an operation test of the light notification device 10 at the time of
maintenance or when canceling an alarm at the time of use. The cylinder cover 12 has a
cylindrical shape, and the front surface portion thereof is formed of a translucent porous plastic
plate 12a, and the side surface portion thereof is formed of a plastic transparent cylinder 12b.
Examples of the material of the plastic include acrylic resin and polycarbonate resin. The inner
surface and / or the outer surface of the side plastic transparent cylinder 12b, or both of them,
are processed to diffuse light, diffusely reflect, for example, corrugated or cut. The light emitted
from the back of the speaker unit 1 is transmitted through the transparent resin diaphragm 3,
passes through the inside of the cylindrical casing 11, and is diffused and irradiated from the
front porous plastic plate 12a and the side plastic transparent cylinder 12b. . The sound
generated from the speaker unit 1 passes through the porous plastic plate 12a and propagates
into the room.
The cylinder cover 12 is slid back and forth by the cover drive unit 13. Specifically, in the
example of FIG. 3, the cover drive unit 13 generates a magnetic field by an electric current to
adsorb the iron core, thereby causing a solenoid for moving the action piece 13 a fixed to the
plastic transparent cylinder 12 b in parallel. It uses a valve. A cylindrical switch 16 for detecting
a state in which the cylindrical cover 12 is stored and a state in which the cylindrical cover 12 is
popped are attached to the cylindrical casing 11. FIG. 4 is a block diagram showing the control

board 14 and the electrical connection around it. A CPU 18 is mounted on the control board 14,
and the CPU 18 is connected to a network (LAN) through a signal input / output circuit 20. A
management center (not shown) is connected to the network, and the management center sends
various command signals to the main illumination notification apparatus 10 through the
network, and the illumination notification apparatus 10 transmits various status signals to the
management center through the network. Send out A start switch 15, a cylinder switch 16, and a
mode setting switch 19 are connected to the CPU 18. As described above, the activation switch
15 is a switch for causing the tube cover 12 to pop out manually in an alarm state, cause a voice
or an alarm to be emitted from the speaker unit 1, and to release the alarm. The cylinder switch
16 is a mechanical switch that detects the open / close state of the cylinder cover 12 in order to
confirm the operation of the cover drive unit 13. This confirmation signal is collected at the
control center. The mode setting switch 19 is a switch for setting whether to enable or disable
the operation of the start switch 15. Further, the CPU 18 is connected to the cover driving unit
13, the light source mounting substrate 5, and the amplifier 17 for driving the speaker unit 1.
Although the cover drive unit 13 may use a solenoid valve as described above, various drive
mechanisms (actuators) other than the solenoid valve can be adopted as described later in the
embodiment. When an emergency signal is input to the CPU 18 from the LAN through the signal
input / output circuit 20, the CPU 18 can synchronize plural programs with one another to
control illumination and voice in an interlocked manner, and illuminate and voice. At the same
time as the control of the cover, the drive of the cover can be controlled at the same time. The
control pattern is arbitrary, but the following patterns can be exemplified. <Control pattern for
cover drive unit 13> Normal: Tube cover stored state Emergency: Tube cover pop-out state
<Control pattern for amplifier 17> Normal: General guidance by synthetic voice Emergency:
Alarm sound for emergency notification (The tone range and repetition cycle are appropriately
set according to the installation purpose of the lighting notification device.) <Control pattern for
the light source mounting board 5> Normal: Continuous lighting Emergency: Flashing or flow
rotation (Blinking cycle or color is illumination It sets up suitably according to the installation
purpose of an informing device.
The combination of the above-described control patterns can be used as a normal lighting device
by making the cylinder cover 12 continuously light in a stored state in normal times, and normal
guidance by synthetic voice can be performed. In an emergency, the cylinder cover 12 pops up
and blinks, and an alarm sound can be issued to notify of an emergency. Hereinafter, another
structural example of the cover drive unit 13 will be described. FIG. 5 is a mechanism diagram

the solenoid valve 42. Direction) is arranged so that it can be put in and out.
In this structure, when a person presses the tube cover 12 by hand, the locking claw 43 abuts on
the corrugated portion of the side surface of the tube cover 12 to fix the back and forth
movement of the tube cover 12. In an emergency or the like, the locking claw 43 is retracted by
the solenoid valve 42. By this operation, the locking of the locking claw 43 is released, and the
tube cover 12 jumps forward by the spring force. When the emergency state disappears and
returns to normal, a person pushes the tube cover 12 by hand. FIG. 8 is a mechanism diagram
