Description

[Detailed explanation of the idea] The present invention relates to a decorative device based on light and sound.

In a decorative device that uses the light of a light-emitting object such as a candle, if a device that plays sound, especially music, is built-in, it is possible to increase the decorative effect not only visually but also aurally. Small-sized sound generating means such as so-called electronic music boxes with stored information have also been put into practical use.

By the way, when such a sound generating means is built into the above-mentioned decorative device, when using it, for example, it is necessary to light a candle and then operate a switch to generate the sound, making it difficult to handle. It becomes complicated, and since the switch is provided, the structure becomes complicated, and there is a risk that the appearance may be impaired.

The present invention aims to eliminate such problems.The purpose of this invention is to make it possible to simultaneously play music by simply lighting a light-emitting object such as a candle.It is easy to use, has excellent appearance, is easy to configure, and is free from malfunctions. There is no need to provide a decorative device based on light and sound.

In order to achieve the above objectives, the present invention is applied to a decorative device equipped with a light-emitting body such as a candle that can be turned on and off at will, and its main component is a light detection device such as a photodiode that detects only the light of the light-emitting body. and a sound generating means such as an electronic music box that emits sound upon detection by this light detecting means, and by detecting only the transmitted light that has passed through the inside of the candle, it can emit music, etc. at the same time as lighting the candle. The music is characterized by being made to flow, and by extinguishing the fire, the music, etc. is stopped.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an overall perspective view of a decorative device according to the present invention. First, the overall external configuration will be described with reference to the same figure. The decorative device designated by reference numeral 1 has a base 2 at its lower part and a light emitting part 3 at its upper part. The base part 2 consists of a cylindrical support part 4 and a base part 5 whose hem part is widened to prevent it from falling down. On the other hand, the light emitting part 3 has a hollow oval shape and consists of a decorative cover 6 made of glass and a candle 8 housed inside. This decorative cover 6 has an opening 7 at the top and an opening at the bottom, and can be attached to and detached from the support 4. Further, the decorative cover 6 is formed into a translucent shape with various colors and patterns applied thereto. Note that the base 2 is also given a desired color and pattern, taking into consideration the appearance design.

Next, the internal configuration of the device 1 will be explained with reference to FIG. A cylindrical candle support 9 having a bottom is provided on the upper part of the support column 4, and the candle 8 is inserted and raised therein.

On the other hand, inside the support 4, there is built-in an LSI 11 that stores melody information, a battery 12, and a printed wiring board 13 on which various parts are mounted, as well as a speaker 14 that plays the melody information read from the LSI 11 as sound. and sound generating means 1
5.

Further, a photodiode 16 is disposed below the outer periphery of the support 9, and this is a storage section 9 in which a part of the periphery of the support 9 is bulged outward as shown in FIG.
It is attached inside a and is configured as a light detection means 17. As shown in FIG. 3, the storage portion 9a has a substantially triangular longitudinal section, and a reflective portion 9b is provided on the inner surface of the upper inclined portion. Further, the photodiode 16 is disposed so as to face the reflecting section 9b, so that the reflected light from the reflecting section 9b can be detected. As a result, in the detection means 17, the light from diagonally downward, that is, the transmitted light that has passed through the inside of the candle 8, is detected by the reflection section 9b.
L ₁ (diffuse reflected light), or direct light from candle 8a whose height has decreased as candle 8 burns out over time
L ₂ is detected through the respective reflecting portions 9b, and unnecessary light from the outside such as indoor light is not detected at all.

FIG. 4 shows an electrical circuit diagram of the decoration device 1.
The LSI 11 is a chip element mainly composed of a ROM that stores digitized melody information.
This LSI 11 is connected to the speaker 14 via an amplifier circuit 18, the battery 12 via a main switch 19, and the photodiode 16 to required terminals, as well as a volume adjustment circuit 20 and necessary auxiliary circuits. Connect and wire. With the above circuit configuration, when the photodiode 16 detects light with the main switch 19 in the ON state, a detection current is supplied to the LSI 11, and by this detection,
The melody information is read out in the LSI 11, and the read melody information is D/A converted within the LSI 11, and music based on the melody information is played from the speaker 14. This LSI
The reading of the melody information in step 11 is executed only when the photodiode 16 is detecting light, and the reading is stopped when the light disappears.

That is, in the present decoration device 1, when the candle 8 is lit, the light detection means 17 immediately detects the light from the candle, and the sound generation means 15 plays music. Moreover,
Since the light detection means 17 is configured to detect only the light from the candle 8, it is completely unaffected by external light such as indoor light and does not malfunction.

In the above embodiment, the candle 8 is used as an example, but other similar light emitting bodies such as alcohol lamps can be used, and the sound generating means 15 can generate any sound such as music, chimes, voices, etc. can be done. Furthermore, although the present invention has been applied as a decorative device, it may also be applied to other lighting devices, alarm devices, etc.

As described above, the decoration device according to the present invention is easy to handle because it plays music by simply lighting a light-emitting object such as a candle, and also has a simple structure and excellent appearance because it does not require a switch or the like.

Further, since only the light emitted by the light emitting body is detected, it is possible to provide a highly reliable decorative device with less malfunction.
