Abstract

(57) [Summary] [Purpose] To provide a speaker built into a lighting fixture that does not require installation space for a single speaker, is highly space efficient, and does not give a sense of discomfort in terms of design. [Structure] The device main body 1 has reflective plates 2A, 2B, and 2C separated from each other on both sides and in the center arranged in the longitudinal direction.
The central reflecting plate 1C has a substantially flat plate shape, and both ends thereof are fixed to the inner ceiling surface of the appliance main body 1 via an insulator 4. Furthermore, drive units 3 are attached to the upper surfaces of both sides of the center of the central reflecting plate 1C, respectively. Drive unit 3
A drive signal is applied via a transformer attenuator 5 attached to the outer ceiling surface of the instrument main body 1, and the reflector plate 1C is driven to vibrate.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to speakers built into lighting equipment installed on ceilings, walls, etc. It is.

0002

[Conventional technology]

Conventionally, speakers used for broadcasting emergency announcements inside buildings were independent speakers. It was usually installed on the ceiling, wall, etc. In addition, speakers installed in the so-called system ceiling were conventionally used as lighting fixtures. Because it is installed using a part of the interior or a part of the slit in the ceiling component, there is a certain Some installation space was required.

0003

[Problem that the idea aims to solve]

As mentioned above, conventional speakers take up a lot of space when installed in buildings. Because it is necessary, space efficiency is poor and it is also a negative element in terms of design. There was a case. This invention was devised in view of the above-mentioned problems, and its purpose is to The light fixture itself functions as a speaker, eliminating the need for installation space for a single speaker. , built-in lighting fixtures that are space-efficient and do not look out of place in terms of design. to provide the best speakers.

0004

[Means to solve the problem]

In order to achieve the above-mentioned purpose, this invention uses the reflector of a lighting equipment as a diaphragm. It is driven by a drive unit.

[0005]

[Effect]

Therefore, the speaker built into the lighting equipment of the present invention uses the reflection plate of the lighting equipment as a diaphragm. Because it is driven by a drive unit, the installation space is shorter than when installing a single speaker. There is no need for a pacer, and the exterior looks like a lighting fixture, so it looks strange in terms of design. It doesn't give a feeling.

[0006] In addition, the reflector of lighting equipment is almost a flat plate and is partially fixed, so it is susceptible to vibration. and provides good quality sound.

[0007]

【Example】

The present invention will be explained below with reference to examples. Figure 1 shows an example of a lighting device in which two lamps L, such as straight tube fluorescent lamps, are installed side by side. This is a cross-sectional view of an example, and inside the instrument main body 1 with an opening on the bottom, there are two sections on both sides and the center. The reflective plates 2A, 2B, and 2C are arranged separately in the longitudinal direction. These, reflector plate 2A , 2B, and 2C constitute a reflecting plate portion having a generally inverted U-shaped cross section as a whole.

[0008] The central reflecting plate 1C has a substantially flat plate shape, and both ends thereof are connected with an insulator 4 interposed therebetween. and is fixed to the inner ceiling surface of the appliance body 1. Then, as shown in Figure 2, A drive unit 3 is attached to the top surface of each, and this drive unit 3 allows the reflection Plate 1C is driven as a diaphragm to vibrate, similar to a speaker using a flat diaphragm. It constitutes a loudspeaker.

[0009] The drive unit 3 is an MC die commonly known as an actuator unit. A full range Namic type was used and was installed on the outer ceiling surface of the fixture body 1. A drive signal is applied via a transformer attenuator 5. The sound reproduced by the vibration of the reflector 2C driven by the drive unit 3 The voice will be radiated downward as shown by the arrow in FIG.

0010 Figure 3 shows a cross-sectional view of an example when used in a Danlight lighting fixture, and shows the basic Specifically, the drive unit 3 is mounted on the back side of the central reflector 2C', similar to the embodiment shown in FIG. It is designed to drive the central reflector plate 2C'. Incidentally, the lamp L used is an incandescent lamp, and the peripheral reflector 2A' is a cylindrical one. is used.

[0011]

[Effect of the idea]

This invention uses the reflector of the lighting equipment as a diaphragm and is driven by the drive unit. Compared to installing a single speaker, installation space is not required, and the appearance is Because it looks like a lighting fixture, it has the effect of not creating a sense of incongruity in terms of design. The reflector of the lighting equipment is almost a flat plate and is partially fixed, so it is susceptible to vibration. This has the effect of providing good sound quality.
