Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a book that generates auditory sounds corresponding to visual information on a plurality of pages.

[Prior Art] Conventionally, a spiral audio recording groove similar to that of a record is formed in a part of a page, and a special reproduction device with a rotating reproduction needle is placed on this recording groove.
There are books that make reading even more enjoyable by playing back the sounds recorded in the recording grooves.

However, in order to form the spiral audio recording grooves, all or part of the pages of these books must be made of a special material similar to that of vinyl records, making them expensive and requiring special playback equipment. It has the disadvantage that it is inconvenient to handle when necessary. In addition, a ROM is built into the binding section where multiple sheets are bound, and a CPU and audio device for voice synthesis are built into the detachable body of this binding section, and a predetermined voice is generated by pressing the press switch built into the sheet. An embankment has been proposed to generate it (Japanese Unexamined Patent Publication No. 1983-38295). However, since a pressure switch is provided on each sheet, the connection between each sheet and the binding section, and the connection between the binding section and the main body are complicated. Therefore, there are problems in that the reliability of the circuit connection is reduced, the structure is complicated and expensive, and the productivity is poor.

There has also been a proposal for a device that stores an IC chip, battery, speaker, etc. inside the cover and generates sound when the cover is opened (Utility Model No. 59-32458).
However, in this case, when the pages of the book are open, light does not enter the phototransistor on the cover, so not only is it impossible to generate sound, but there is also the problem that it is not possible to generate sound that corresponds to each page. Ta.

[Purpose of the invention]

The present invention has been made in view of these drawbacks, and its purpose is to make it possible to generate an auditory sound corresponding to the visual information of each page with an inexpensive and simple operation, and to bind each page to form a book. It is an object of the present invention to provide a book which is easy to manufacture without requiring any circuit connection, and which can automatically generate sounds corresponding to each page.

[Structure of the invention]

According to the present invention, this purpose is to provide a light detecting means for automatically detecting the currently opened page among a plurality of pages by selectively blocking light with a light blocking piece provided on each page;
a memory storing auditory information corresponding to each of the visual information of a plurality of pages; a control means for reading auditory information corresponding to the page detected by the detection means from the memory; an auditory sound signal generating means for generating an auditory sound signal;
This is achieved by a book characterized in that a sound generating means for generating an auditory sound based on the auditory sound signal and a battery are provided on either the front cover or the back cover.

〔Example〕

The present invention will be explained in detail below.

FIG. 1 is a block diagram showing an embodiment of the present invention, in which 1, 1 to 1, n are optical sensors as detection means for detecting the currently opened page among n pages;
3 is a microcomputer (hereinafter referred to as CPU), and 3 is a memory that stores auditory information corresponding to visual information such as paintings, photographs, poems, or musical scores on each page. The CPU 2 functions as a control means for reading auditory information corresponding to the page detected by the detection means from the memory 3. 4 is a programmable sound generator (hereinafter referred to as PSG) as an auditory sound signal generating means for converting the auditory information read from the memory 3 by the microcomputer 2 into an auditory sound signal; 5 is a planar speaker; 6 is a planar speaker; It is a power source such as a mercury battery.

FIG. 2 is a plan view and a cross-sectional view showing the structure of a book incorporating these elements.
is attached to a cutout portion 9 of a cover 7 which is made of paper and covered with paper or a resin board such as a mount or foamed urethane foam with a thickness of about several mm. On the other hand, the optical sensors 1, 1 to 1, n are arranged in a row along one side of each page on the left side of the cover 7, and are arranged at different positions for each page or for each page that requires a different auditory sound. When indoor light is blocked by the protruding pieces 8, 1 to 8, n serving as light blocking pieces, a detection signal of the currently opened page is supplied to the CPU 2.

In such a configuration, as shown in FIG. 2, when the page to which the second protruding piece is attached is opened, light to the optical sensors 1, 1 and 1, 2 is blocked. Therefore, the CPU 2 detects from the output signals of the optical sensors 1, 1 to 1, n in this state that the currently opened page is the page to which the second protruding pieces 8, 2 are attached. . Therefore, the CPU 2 reads auditory information corresponding to this page from the memory 3 and sequentially supplies it to the PSG 4.

Upon receiving the auditory information, the PSG 4 converts the information into an analog auditory sound signal and supplies it to the speaker 5 .

As a result, the speaker 5 generates an auditory sound corresponding to the content written on the page to which the second protruding pieces 8, 2 are attached. In this case, for example, when outputting music, the auditory sound information is composed of information representing the pitch, amplitude envelope, volume, and length of the sound; The information is immediately transferred to the PSG4, and the length information is set as control information for the timer in the CPU2, and when the time corresponding to this length information has elapsed, the pitch of the next auditory sound to be generated is determined. , amplitude envelope, and information representing volume are read out and supplied to the PSG 4. The pitch of the sound is
If CPU2 has an 8-bit configuration, up to 256 types can be selected. Furthermore, if it is a 4-bit configuration, it is possible to select up to 256 types by using a 2-word configuration.

Please input audio information into memory 3 in advance.
By using a speech synthesis circuit as the auditory sound signal generating means, it is also possible to output an explanation of the corresponding page in the form of speech.

In this way, by incorporating the auditory sound generation means into the cover of the book, it is possible to easily generate the auditory sound corresponding to the visual information written on the desired page without using any special reproduction device. As a result, the enjoyment of reading can be further enhanced, and even visually impaired people can enjoy reading through their ears.

FIG. 3 is a block diagram showing another embodiment of the present invention, in which a carrier wave signal of a predetermined frequency generated from an oscillator 10 is inputted to a modulator 11, where the carrier wave signal is converted into an auditory sound signal from the PSG 4. Yotsute AM
The signal is modulated or FM modulated, amplified by an amplifier 12, and then transmitted from an antenna 13 to generate auditory sound via an external AM radio or FM radio. Here, it is desirable that the antenna 13 be buried in the cover 7.

With such a configuration, it is possible to generate auditory sound with even better sound quality, creating a three-dimensional enjoyment.

In the above embodiment, pages are detected by selectively blocking light from the optical sensor, but if the output of the optical detection means such as the optical sensor is used to charge the battery 6, the battery can also be charged. This is no longer necessary, making it even easier to use.

In addition, memory 3, CPU 2, PSG 4, speaker 5,
Furthermore, an oscillator 10, a modulator 11, an antenna 13
etc. may be stored not only within the cover 7 but also on the back cover. In any case, light detection means, memory, control means, auditory sound signal generation means, sound generation means, batteries, etc.
By housing all the circuit components required from page detection to sound generation together on either the front or back cover, the circuit wiring becomes very simple and manufacturing becomes easy.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, by incorporating an auditory sound generating means into the cover of a book, etc., it is possible to easily write information on a desired page with an inexpensive structure and without using a special playback device. It is possible to generate an auditory sound corresponding to the visual information received. As a result, the enjoyment of reading can be further increased, and even visually impaired people can enjoy reading. Also, light detection means, memory, control means,
All the circuit components required from page detection to sound generation, such as auditory sound signal generation means, sound generation means, batteries, etc., are stored together on either the front or back cover, so the electrical wiring is stored inside the front or back cover. Complete with just that. Therefore, when binding a book, there is no need for electrical wiring for each page, making the binding process very easy and inexpensive. Furthermore, since each page is automatically detected by the optical detection means, it is possible to output detailed audio information corresponding to each page without pressing a switch or the like.
