DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a home BGM device according to the present invention will be described below with reference to the drawings . In the home of General, as shown in FIG.
Is used household fluorescent lamp device L as shown in 1, as shown in the figure, the their many household fluorescent lamp device, so that it can adjust brightness accordingly usually required, for fluorescent lamps The umbrella 1 is configured such that two large and small annular fluorescent lamps 2 and 3 having different looks are mounted. By appropriately using the fluorescent lamps, appropriate lighting required in a room at home can be provided. In the figure,
Reference numerals 4 and 4 denote power supply units of the fluorescent lamps 2 and 3, 5, 5, and 5, respectively.
Is a support for retaining the fluorescent lamps 2 and 3;
Reference numeral 6 denotes a power switch switching string, and reference numeral 7 denotes a storage box in which a power switch, an auxiliary lamp, a glow bulb, and the like are stored. As shown in FIGS. 1 and 2 , the fluorescent lamps 2 and 3 are installed in two tiers, and a gap B is formed between the fluorescent lamps 2 and 3 and the bottom surface of the storage box 7. FIG. 3 is a bottom view of the state in which the BGM device 8 is mounted as viewed from below. As shown in FIG. 4 , the BGM device 8 includes a speaker 11 and a speaker 11 in a box 10 provided with a support 9 on the outer side .
A voice playback unit 12 an electrical circuit is incorporated as shown in 5 is configured to be received, further, box 10, be formed in a fan shape, the notch 40a of FIG. 3 to shown in FIG. 4
Co-down compact disk 25a and the magnetic tape 25b, radio
An insertion portion 30 in which the audio output means 25 including the device 25c is housed is formed. In addition, the audio reproducing unit 12
Are connected to an antenna 13 also serving 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. Figure 5 constitutes a BGM device 8 B
FIG. 4 is a circuit block diagram showing a connection state between the audio reproduction unit 12 and the audio output unit 25 of the GM circuit setting unit .
Inside the compact disk 25a or magnetic tape 25b
Is a sound source of the radio 25c, for example, a changeover switch
Etc. can be selected appropriately by operating
The voice signal output unit 26 outputs a voice signal of the selected sound source.
Has the function of modulating a high-frequency signal. And sound
The modulated high-frequency signal from the voice signal output unit 26
The high-frequency signal received by the audio signal input unit 16 provided in the live unit 12 and transmitted from the transmission circuit 17 as shown in FIG.
And a high-frequency signal that differs only by a low frequency , and the frequency conversion circuit 18 reduces the frequency to an 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 the low-frequency amplification circuit 21 having the built-in amplitude compression circuit.
Transport to By passing the signal through the amplitude compression circuit of the low-frequency amplifier circuit 21, the input signal of high amplitude is suppressed, and the sound is adjusted to a quiet sound as a whole. This sound signal is transmitted to the speaker 11
To be fired into a room in a home. By the way, the power supply of the audio reproduction unit 12 is divided into two by the power switch circuit 22. The power switch circuit 22 has a built-in smoothing circuit, and an output from the smoothing circuit is supplied to circuits such as the audio signal input unit 16 to the detection circuit 20. In the + B1 portion in the drawing, a current of several mA is set to flow constantly. In addition, the high-frequency
Upon receiving the signal, the signal current flows to the frequency conversion circuit 18 leads to part of the signal current to the power switch circuit 22, rectified by the detector circuit of the power supply switch circuit 22, a switching circuit incorporated in the signal To supply the power + B2 to the low-frequency amplifier 21. With such a configuration, the current flowing constantly is reduced . FIG. 6 shows a second embodiment of the present invention.
In this case, the socket part 30 is arranged so that the auxiliary lamp 31 and the glow light bulb 32 protrude as household fluorescent lamps, and the box 10 is formed in a semicircular shape, and BG
On the M device 8 side, a cutout portion 40b indicated by a broken line is provided to avoid it, and the insertion portion 30 shown in the first embodiment is formed in the cutout portion 40b. In this case, the same operation and effect as those of the first embodiment can be obtained.
