FIG. 4 is a vertical cross-sectional view of the device of the present invention taken along the line AA,

FIG. 5 is a circuit block diagram showing the basic circuit configuration of the device of the present invention. At home,

FIG. 1 shows a domestic fluorescent lamp L as shown in FIG. 1 is used, and as shown in the figure, many of these household fluorescent lamps usually have the brightness adjustable so that the brightness can be adjusted as needed. Two large and small emotional fluorescent lamps 2 and 3 having different looks are mounted in the fluorescent lamp umbrella 1. Then, by properly using the above fluorescent lamps, it is possible to provide appropriate lighting required in a home room. In the figure, 4 and 4 are power supply parts of the fluorescent lamps 2 and 3, 5 and 5 are supporting metal fittings for locking the fluorescent lamps 2 and 3, and 6 is a power supply. A string for switching the switch, and 7 is a storage box for storing a power switch, an auxiliary lamp, a glow bulb, and the like.

FIG. 1 and

As shown in FIG. 2, the fluorescent lamps 2 and 3 are connected in two stages, and a space B is formed between the fluorescent lamps 2 and 3 and the bottom surface of the storage box 7. Seen from below with the BGM device 8 attached

FIG. 3 is a bottom view of FIG. The BGM device 8 is

As shown in FIG. 4, a speaker 11 and an electric circuit box 12 containing the electric circuit shown in FIG. 4 are housed in a box 10 having a support metal fitting 9 on the outer side. Further, the box 10 is formed in a fan shape, and the notch 40a is formed in the notch 40a.

FIG. 3 and

FIG. 4 is formed with an insertion portion 30 for accommodating a voice output means 25 such as a compact disc, which will be described later, or a magnetic tape, a radio or the like. Further, the electric circuit box 12 is connected to an antenna 13 that also serves as a power switch switching string and a power outlet 14 for supplying power. Further, the outlet 14 is connected to a power line (not shown) for home use.

FIG. 5 is a circuit block diagram showing a connection state between the electric circuit box 12 and the audio output means 25, which constitute the BGM device 8, respectively. For example, in the audio output means 25, a compact disc 25a, The audio signal output unit 26 such as the magnetic tapes 25b and 25c is configured to be connected to the audio signal input unit 16 of the electric circuit box 12. The audio signal output unit 26 is configured to input and output an audio signal via a control means 27 such as a CPU, and a command for signal selection to the control means 27 is connected to the control means 27 by a laser beam. The receiving section 27a is configured to be controlled and controlled based on a signal instructed by operating the portable control device 28. This portable control device 28 can select the voice output means 25 such as the compact disc 25a and the magnetic tapes 25b and 25c, and can select and instruct a desired voice signal stored in the selected voice output means 25. The command is transmitted from the laser signal generator 28a of the portable control device 28, and separation control is possible. That is, the audio output signal output from the audio output means 25 is received by the audio signal input section 16 provided in the electric circuit box 12, and mixed with the signal from the transmission circuit 17 as shown in the figure, The frequency conversion circuit 18 is configured to reduce the intermediate frequency. Further, the signal dropped to the intermediate frequency by the frequency conversion circuit 18 is amplified by the amplification circuit 19, detected by the detection circuit 20, and then conveyed to the low frequency amplification circuit 21 having a built-in amplitude compression circuit for adjusting the width of the dynamic range. To do. By passing through the amplitude compression circuit of the low-frequency amplification circuit 21, the high-amplitude input signal is suppressed and the overall sound is adjusted to be quiet. This sound signal is sent to the speaker 11 and is emitted to the space inside the home. In this way, the home audio device of the present invention is constructed. The power source of the electric circuit box 12 is divided into two by the power source switch circuit 22. Further, the power switch circuit 22 has a built-in smoothing circuit, and the output from the smoothing circuit is supplied to circuits such as the high frequency amplifier circuit 16 to the detection circuit 20. That is, it is set so that a current of several mA always flows in the portion + B1 in the figure. When the BGM device 8 receives a radio wave from the home audio 23, a signal current flows through the frequency conversion circuit 18. However, a part of this signal current is received and guided to the power switch circuit 22 to detect the power switch circuit 22. The signal is rectified, the built-in switching circuit is activated by the signal, and the power supply + B2 is supplied to the low frequency amplification circuit 21. With this configuration, the current that constantly flows is reduced. In this embodiment, the laser beam is used as the signal carrier, but the signal carrier is not limited to this, and a carrier such as infrared ray may be used. According to the device of the present invention having the above-described configuration, the BGM device 8 is detachably attached to the domestic fluorescent lamp A, so that the BGM device 8 can be easily attached to the domestic fluorescent lamp A, and Since the BGM device 8 can be freely controlled by the laser signal from the laser signal generation unit 28a of the portable control device 28 which is located away from the BGM device 8, the BGM device 8 can be conveniently used. The versatility of the device itself is increased, and the BGM device 8 can be inexpensively and easily used for home use. FIG. 6 is a circuit block diagram showing a second embodiment of the device of the present invention, in which infrared rays are used as signal transmitting means. Descriptions of equivalent members and parts described in the first embodiment will be omitted here. In the case of this embodiment, an audio signal is converted into an infrared signal through an infrared signal output means 32 and a modulation circuit 31 which modulates the output part of the audio output means 25 of the home audio device 23 into an infrared signal, and the infrared signal is transmitted. It is configured to transmit from the signal transmission unit 32a. In this case, the BGM device 8 includes an infrared input section 13a and a compression circuit 13 for demodulating an infrared signal input from the infrared input section into an audio signal and converting the received frequency range into BGM broadcasting. It is provided. In this case, the audio selected by the home audio device 23 can be enjoyed as the BGM broadcast via the BGM device 8 by using the home audio device 23, but the separation control can be performed in the first embodiment. Has the same effect as.
