Abstract

PURPOSE:To steep in the world of AV sound without being conscious of the sound source by incorporating a speaker for sound reproduction into a lighting fixture matching as an interior decoration. CONSTITUTION:A lighting fixture 1 and a speaker box 2 are integrated and mounted on a ceiling 3. Four speaker units 4 are installed in a speaker box 2. A circular fluorescent lamp 5 and an incandescent lamp 6 are installed downward and two bar shaped fluorescent lamps 7 and 4 incandescent lamps 8 are installed upward, in the lighting fixture 1. At this place, indirect illuminating lamps 7 and 8, and direct illuminating lamps 5 and 6 are capable of controlling freely of the combination of lighting and illuminance by the remote control according to using purpose of the room. Thus, the arranging the sound source for sound in a most effective position can be made, matching with the interior design.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides lighting and surround sound fields that match the daily life scene in living spaces such as homes.
This article relates to an illuminated speaker system that creates an environment where you can enjoy music and videos more realistically.

[Conventional technology]

When enjoying surround sound playback of music programs or movie software in the living room of a home, the playback space was constructed by attaching sub-speakers to walls, ceilings, etc. in addition to the main speakers placed in the front.

[Problem to be solved by the invention]

However, in many cases, lighting equipment is installed at the location where the sub-speaker is installed, making it impossible to reproduce a sound field with excellent acoustic effects. Moreover, it was troublesome to install the speakers, and it was often difficult to create a design that would match the interior design of the room.

In addition, when listening to music or enjoying movie software, the light from the lighting equipment gets into the eyes, making it difficult to fully immerse yourself in the world of AV.

The present invention was made to compensate for the drawbacks of the conventional products as described above, and its purpose is to promote music and FIJ! We provide equipment that integrates sound and light to create a comfortable AV surround sound viewing environment, making it possible to freely adjust and control indirect sound and indirect lighting according to the living situation where you enjoy both software. It's there.

[Means to solve the problem]

Therefore, the present invention is characterized in that the speaker system that emits sound and the lighting equipment are integrated into an integrated structure.
Lighting equipment has a means to switch between direct light and indirect light and dimming depending on the purpose of use, and speaker systems have means to add indirect sound signals extracted from music and movie software as input. It is also characterized by having.

[Effect]

By integrating the speaker system and lighting equipment, the surround sound source can be placed in the most effective position while matching the interior design, and floor space can be used effectively. Moreover, by producing sound and light according to the purpose, - more enjoyable and comfortable AV
You can create space.

〔Example〕

FIG. 1 is a structural diagram of an embodiment of the present invention, and FIG. 2 is a perspective view of the same embodiment.

In these figures, the lighting fixture 1 and the speaker box 2 have an integral structure and are shown attached to the ceiling. Four speaker units 4 are attached to the speaker box 2, and the lighting equipment 1 has a circular dinner light 5 and an incandescent I-bulb 6 facing downward, and two bar-shaped fluorescent lights 7 facing upward. and four incandescent light bulbs 8 are attached.

Here, the indirect lighting lights 7 and 8, which are turned upward, and the direct lighting lights 5 and 6, which are turned downward, can be turned on according to the purpose of the room, such as family gatherings, parties, listening to music or movies, etc. It is possible to freely control the alignment and illuminance with a remote control.

FIG. 3 is a perspective view of another embodiment of the system of the present invention installed in a corner of a room.

A cabinet 12 in which a speaker unit 20 and an incandescent light bulb 11 are integrated is attached to a corner wall 9. A surround sound signal is emitted from the speaker unit 10, and the light from the incandescent bulb 11 is reflected at the corner to provide indirect lighting, effectively creating an AV room environment suitable for enjoying music and movies.

FIG. 4 is a block diagram illustrating one embodiment of surround sound playback in a living room using the system of the present invention.

In the plan view 36 of the living room, two main speakers 17, 8 and 4 corner-type illuminated sub-speakers 28, 29, 30, and 31, and a ceiling-mounted illuminated surround speaker 35 are arranged. ing. Stereo sound is transmitted, and the R two signals are attenuated by 13.1.
4 and the main speaker 1 via the output amplifier 15.16
It will be replayed in stereo from 7.18.

The two signals R branched from the stereo signal are delayed in the delay processing circuit 19 and converted into four signals having a reflected sound structure.
and are supplied via output amplifiers 24, 25, 26.degree. 27 to corner-type illuminated speaker systems 28, 29, 30.degree. 3I of the structure described in FIG. 3, respectively. Furthermore, the two signals branched from the stereo signal, R, become a difference signal in a subtraction circuit, which is extracted as a signal containing many reverberant components, whose frequency is adjusted by a graph ink equalizer 32, and then passed through an attenuator 33 and an output amplifier 34. Reverberant sound is radiated from the center of the room in all directions from the ceiling-mounted lighting surround speaker system 35 having the structure described in FIGS. 1 and 2.

FIG. 5 shows a state in which indirect sound is radiated in a front view 35 of a living room.As an application of the present invention, the illuminance of the lighting is controlled in accordance with the level of the acoustic signal reproduced from the speakers. You can also make the party scene even more fun with the sound and light production. Further, by using the speaker system of the present invention to generate a reverberation signal extracted from a stereo transmission signal and a delayed synthesized sound simulating the reflected sound of a hall, the sense of realism in music reproduction can be enhanced. Further, the speaker system of the present invention may be used for background music by directly adding a music signal, or may be used as an indoor loudspeaker.

Here, we have explained the use in a home living room as an example, but it goes without saying that the scope of use can be expanded to include hotels and offices.

〔Effect of the invention〕

As described above, according to the present invention, by incorporating a speaker for surround reproduction into a lighting fixture that is suitable for indoor interior, it is possible to immerse yourself in the world of AV surround without being conscious of the sound source. Moreover, direct lighting and indirect lighting,
By freely adjusting and switching the brightness using a remote control, you can create a living environment with sound and light that matches various daily life situations, such as when watching movies or music, when family gatherings, or when having a lively party. It becomes possible.
