[Industrial field of application] The present invention is an illumination for creating an
environment in which music and video can be enjoyed more realistically and realistically by the
illumination matched to the living scene and the surround sound sound field in a living space
such as a home The present invention relates to a speaker system with a speaker. [Prior Art]
When enjoying music programs or movie software in surround sound reproduction in a living
room of a home, sub-speakers are attached to walls, ceilings, etc. in addition to the main speakers
placed at the front to constitute a reproduction space Was. [Problems to be Solved by the
Invention] However, in the above-mentioned attachment of the sub-speaker in many cases, a
lighting fixture is often installed at the position, and sound field reproduction with excellent
sound effects could not be performed. Moreover, the installation of the speakers was
troublesome, and in many cases, it was difficult for the interior to have a matching design. In
addition, when listening to music or enjoying movie software, the light from the lighting
equipment gets into the eyes, and there is a drawback that it interferes with viewing and can not
be absorbed in the AV world. The present invention has been made to compensate for the
disadvantages of the prior art as described above, and the purpose is to make music and FIj!
Indirect sound and indirect lighting can be adjusted and controlled freely according to the
Sumikatsu scene that enjoys both software, providing a device with integrated sound and light
that can realize a comfortable AV surround sound viewing environment Where are you going?
[Means for Solving the Problems] Therefore, the present invention is characterized in that a
speaker system for emitting sound and a lighting device are integrally formed, and in the lighting
device, direct light and indirect light are used according to the purpose of use. It is also
characterized in that it comprises means capable of switching between light and dimming, and
that the speaker system comprises means for adding an indirect sound signal extracted from
music or movie software as an input. [Operation] By integrating the speaker system and the
lighting apparatus, the surround sound source can be disposed at the most effective position
while matching to the indoor design, and the floor area can be effectively utilized. . In addition,
by producing sound and light according to the purpose, it is possible to create an AV space that
is pleasant and comfortable. FIG. 1 is a structural view of an embodiment of the present
invention, and FIG. 2 is a perspective view of the same embodiment. In these figures, the
luminaire 1 and the speaker box 2 are integrally formed, and a state in which the ceilings # 3 and
# 2 are attached is shown. Four speaker units 4 are attached to the speaker box 2, and a circular
fluorescent lamp 5 and an incandescent i bulb 6 are downward directed to the lighting fixture 1,
and two rod-shaped fluorescent lamps 7 directed upward And four incandescent bulbs 8 are
Here, the indirect lighting lamps 7 and 8 mounted upward and the direct lighting lamps 5 and 6
mounted downward are used as a group of spotlights according to the purpose of use of the
room, such as family gatherings, parties, music and movie appreciation, etc. It is possible to freely
control the setting and the illumination with a remote control. FIG. 3 is a perspective view of
another embodiment where the system of the present invention is attached to a corner of a room.
On a corner wall 9 is mounted a cabinet 12 in which a speaker unine 20 and an incandescent
lamp 11 are integrated. From the speaker unit 10, a surround sound signal is emitted, and the
light of the incandescent lamp 11 is reflected indirectly at the corner to create an effect of
providing an AV room environment suitable for enjoying music and movies. FIG. 4 is a block
diagram illustrating one embodiment of surround sound re-use in a living room using the system
of the present invention. In the living room plan view 36 two main speakers 17 and eight subspeakers 28, 29 and 30.31 with corner type illumination and a surround speaker 35 with ceiling
mounted illumination are arranged. ing. The two signals of stereo sound transmission and R are
retransmitted from the main speaker 17.18 via the attenuator 13.14 and the output amplifier
15.16. Two signals branched from one more stereo signal, R is delayed by the delay processing
circuit 19 and converted into four signals having a reflected sound structure, and the attenuator
20 ° 21.22.23 and the output amplifier 24, 25 It is supplied via the 26 ° 27 respectively to the
corner type illuminated speaker system 28, 29, 30 ° 3 I of the structure described in FIG.
Further, two signals branched from the stereo signal, R is a difference signal in the subtraction
circuit, is extracted as a signal containing a large amount of reverberation component, is
frequency-adjusted by the graph ink equalizer 32, and is transmitted through the attenuator 33
and the output amplifier 34. From the ceiling mounted illumination surround speaker system 35
having the structure described in FIGS. 1 and 2, reverberation is emitted from the center of the
room toward four directions. FIG. 5 shows the radiated state of indirect sound in the living room
front view 35. As an application of the present invention, by controlling the illuminance of the
illumination in accordance with the level of the acoustic signal reproduced from the speaker.
Party-You can make the scene more fun by directing sound and light. Also, by combining the
reverberation signal extracted from the stereo transmission signal and the delayed synthesized
sound simulating the reflected sound of the hole from the speaker system of the present
invention, the sense of reality of music reproduction can be enhanced.
In addition, a music signal may be directly added to the speaker system of the present invention
for use as background music, or may be used as an indoor speaker for loudspeakers. Here, the
use in the living room of the home has been described as an example, but it is of course possible
to extend the range of use to a use in a hotel or office. [Effects of the Invention] As described
above, according to the present invention, by incorporating a speaker for surround reproduction
in a lighting fixture matched as an interior interior, the user can be immersed in the world of AV
surround without being aware of a sound source. What's more, with direct lighting, indirect
lighting, and the ability to freely adjust and switch brightness with a remote control etc., when
watching a video or music carefully, when a family gathers, etc. with a mutching noise in various
life scenes such as a lively party It becomes possible to create the living environment of light.
