Description

[Detailed Description of the Invention] This invention relates to a saucer with a built-in melody generator.

The purpose is to provide, with a simple structure, an interesting saucer which generates a melody for a certain period of time by lifting, for example, a coffee cup or the like on the saucer.

In order to achieve this purpose, this invention provides a melody generator body by arranging a melody IC, a dry cell battery, and a speaker made of a piezoelectric semiconductor on a board so that the whole is flat, and the melody generator body has a built-in A light sensor connected to the one-shot multi-vibrator is arranged, and the light sensor operates the melody generator main body for a certain period of time.The melody generator main body is arranged inside a synthetic resin lid body. is disposed in a water-tight manner on the bottom thread cutout of the saucer body, the saucer body is made of a translucent material, and the optical sensor is disposed within the lid body at a position where it can sense light from the top surface of the saucer body. It is characterized by

An embodiment of this invention will be described below based on the drawings. In the figure, 1 is the main body of the melody generator, which includes a melody IC 2 which has a built-in melody generation circuit and a one-shot multivibrator as its switching circuit, a speaker 3 made of a piezoelectric semiconductor as its external components, a dry battery 4, and a CDS.
The optical sensors 5 are arranged and fixed to a substrate 6 made of paper, plastic, or the like so that the whole has a flat plate shape. The one-shot multivibrator operates a melody generation circuit for a certain period of time in response to an ON signal from the optical sensor 5. The dry battery 4 in the illustrated example is a mercury battery, and the battery 4 is detachably installed via a battery holder 7 which also serves as a contact plate. Therefore, the melody generator main body 1 can be provided as compact and flat as possible.

The melody generator main body 1 constructed in this manner is disposed within the lid 8. The lid body 8 is made of synthetic resin, and a saucer body 9 is provided around the entire inner surface near the mouth edge.
A fitting part 11 is formed to fit in a watertight manner on the outer peripheral surface of the thread cutter 10 at the bottom. This fitting part 11 has a watertight fitting structure similar to a closed container or the like.

The saucer main body 9 is made of magnetism or synthetic resin to have translucency, and the outer peripheral surface of the bottom thread cutter 10 has a fitting part 12 in which the fitting part 11 of the lid body 8 is fitted in a watertight manner. It has been formed.

The illustrated example is constructed by disposing the melody generator main body 1 within the lid 8 and fitting the lid 8 into the bottom thread cutter 10 of the saucer main body 9 in a watertight manner. The present invention is not limited to this, and may be configured as shown in FIG. 3, for example. That is, the peripheral edge of the lid 8 is formed so that it becomes gradually thinner toward the outside, and after the melody generator main body 1 is fixed inside the lid 8, the lid 8 is attached to the thread cutter 10 at the bottom of the saucer main body 9. The thin peripheral portion 8A and the thread cutter 1
It may also be constructed by injecting a silicone resin adhesive 13 into the inside of the hole and fixing it. Note that the power consumption of the melody generator main body 1 is extremely small, and it can be used 3 to 4,000 times with a normal mercury battery, etc., so battery replacement etc. are not taken into consideration in the case of such a configuration. .

Furthermore, although not shown in the drawings, for example, the main body of the melody generator is housed watertight in a flat, translucent synthetic resin box, and the box constructed in this manner is sealed with adhesive tape or adhesive. It can also be pasted.

This idea is constructed as shown above, and the melody generator body 1 is provided by arranging the melody IC 2, the dry cell battery 4, and the speaker 3 made of a piezoelectric semiconductor on the board 6 so that the whole is flat, so it has fewer components and is compact. It can be constructed as something. In particular, since the speaker 3 is made of a piezoelectric semiconductor, the whole can be made thin and compact.
The lid body 8 having the melody generator body 1 can be fitted into the lower thread cutter 10 of the saucer body 9.

In addition, the melody generating device main body 1 includes the device main body 1.
A light sensor 5 connected to a one-shot multi-vibrator built in the melody generator body 1 is arranged so that the light sensor 5 operates the melody generator body 1 for a certain period of time. The saucer body 9 is made of a translucent material, and the optical sensor 5 is placed inside the lid 8 to detect light from the top surface of the saucer body 9. By holding it and separating it from the saucer body 9, the optical sensor 5 disposed at the bottom of the saucer body 9 detects a change in light, and this detection activates the melody generation circuit for a certain period of time via the one-shot multivibrator to generate a melody. do. Then, when light is detected again, the same operation can be repeated. In addition, the optical sensor 5
Since the melody generation circuit is activated via the one-shot multi-vibrator by detecting light from It stops operating after a certain period of time, and there is no inconvenience caused by the melody generation circuit always operating. Therefore, a power switch or the like can be eliminated, and power consumption can also be reduced.

The melody generator main body 1 is disposed within a synthetic resin lid 8, and this lid 8 is watertightly disposed in the bottom thread cutter 10 of the saucer main body 9, so that it can be used for washing dishes etc. after use. This also makes it possible to wash dishes with normal water without interfering with these tasks.

Moreover, since the saucer body 9 is made of a translucent material and the optical sensor 5 is disposed within the lid 8 at a position where it can detect light from the upper surface of the saucer body 9, the use of a cup 13 or the like is avoided. It becomes possible to detect it with light. Therefore, when the cup 13 is separated from the saucer body 9, for example, when drinking coffee, a melody can be generated, making it possible to provide a very interesting coffee cup set.

As explained above, according to this invention, it is possible to provide an interesting saucer that can generate a melody by lifting the cup when drinking coffee, tea, etc.; This has a practically beneficial effect, such as not being exposed to any harmful effects.
