Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a picture book with sounds, which generates sounds according to the content of picture books or books for hobbies or education.

In recent years, picture books with sounds have become commercially available, and picture books are being used as an audio medium that includes sound, rather than as a mere viewing medium.

In view of the trends of the times, this invention was designed to add new functions to picture books, by generating sounds that correspond to the pictures and text content on each page of books such as picture books. The purpose is to give readers more interest and enjoyment in the content written on each page.

(Structure) The present invention embeds at least two optical sensors 2 and 3 in appropriate places such as the edge side of the inner surface of the back and front part 13 of a book such as a picture book, which is composed of front and back covers 12 and 13 and body pages 14, and , 3 are provided with holes 15 vertically communicating with the sensor from the bottom text page directly above the top text page to the top text page, and a neutral density filter 1 is attached to one of the holes 15 for each page. Each time the page is turned over, the respective optical sensors 2 and 3 are activated.
A sound generation control circuit mechanism operated by the electromotive force of the optical sensor 2 is provided on the front and back sides, and includes a corrector 16 that generates different sounds depending on the amount of external light incident thereon and corrects sensitivity according to the amount of external light. 13
It is a picture book that makes sounds and is characterized by its interior decoration.

If the present invention is explained in detail according to the drawings, the first
The figure is a perspective view of the picture book of the present invention, in which 1 is a neutral density filter, 2 and 3 are amorphous silicon solar cells, optical sensors such as CDS, 8 is a memory (ROM),
9 is a digital and analog converter, 10 is a micro speaker, 11 is a battery for power supply, 12 is a front cover, 13 is a back cover, 14 is a text page, 15 corresponds to the optical sensors 2 and 3, and is located at the top of the text page 14. This is a hole provided in vertical communication from the bottom page to the top page. Fourth
The figure is a block diagram illustrating the sound generation control circuit mechanism of the picture book of the present invention.

The picture book of the present invention connects each of the optical sensors 2 and 3 to an analog signal switch 5 and an analog/digital converter 6 through a sensor amplifier 4, and the optical sensor comprises the optical sensor 2 and a neutral density filter 1. A light amount difference signal generated by the difference in electromotive force from 3 is outputted via a converter 6 to operate a microprocessor 7 and a memory 8, and is outputted via a digital/analog converter 9 to a sound generator or speaker 10. A sound generation control circuit mechanism for generating sound is housed in the back cover 13. Further, the sensitivity of the microprocessor 7 is corrected by a corrector 16 which performs dynamic range correction according to the amount of external light incident on the optical sensor 2. FIG. 3A is a graph before correction, and FIG. 3B is a sensitivity graph after correction.

As explained in FIG. 4, a block diagram of the sound generation control circuit mechanism of the picture book of the present invention, the power supply battery 11 of the picture book is turned on and off using the electromotive force of the optical sensor 2 generated when external light is incident. You can do it by doing this.

(Function) By opening the front cover 12 of the picture book of the present invention, external light enters through the hole 15 on the side of the light sensor 2 to which the neutral density filter 1 is not attached, and the light sensor 2
The sensor 2 is irradiated with short-wavelength visible light and near-ultraviolet light, and the sensor 2 generates an electromotive force and becomes energized. On the other hand, since external light is irradiated onto the optical sensor 3 through the neutral density filter 1, and the optical sensors 2 and 3 are irradiated with different amounts of light,
Each of them has a different current flow rate, and the microprocessor 7
Then, a signal of a specific frequency for generating desired sound obtained by operating the memory 8 is transmitted to a converter 9.
The signal can be converted into a digital or analog signal, and sound can be generated from the speaker 10 in accordance with the signal.

In the picture book of this invention, a neutral density filter is attached to each page in one of the two hole holes that are made at appropriate locations such as the front edge of the main text page, and the front cover is When it is closed, the optical sensors embedded and arranged in the back cover are not exposed to external light, and the acoustic power source is not activated, so that no power is consumed. Each time the front cover and text pages are turned over in sequence, the amount of light irradiated to the optical sensor through the hole where the neutral density filter is attached changes, and therefore the amount of photovoltaic power generated in sensors 2 and 3 changes. Then, the sound generation can be controlled in accordance with the current parameters due to the electric power, and different sounds can be generated.

(Effects) This invented picture book can generate different sounds each time you turn each page, and generates sounds such as pseudo voices and sound effects that correspond to the pictures and text written on each page of the picture book or book. As an easy-to-understand picture book or book that is fun and interesting to readers,
It has extremely practical value.
