[Industrial applications]

 The present invention relates to a piano picture book with a karaoke function, which is suitable for use in music training for infants and the like.

[0002]

[Prior Art]

 As a piano-type musical instrument toy that allows infants and others to learn how to play easily and to play without depending on expensive instruments such as pianos and organs, the publication of Japanese Utility Model Publication No. Sho 61-3018 A picture book type piano toy such as that shown in is known. In the case of this picture book type piano toy, a sound generation circuit consisting of a battery power source, an oscillator, a switch group, a speaker, etc. is formed on the upper surface of the board, and the sound of the scale defined by the selection signal from the switch group is generated. It is designed to be generated through a speaker, and when you press a printed key on the keyboard, a sound equivalent to the scale of the key is generated, which is very interesting and has the great advantage of naturally learning how to play while playing. Is something that can be done.

[0003]

[Problems to be solved by the device]

 As described above, a keyboard-type sound generator equipped with a sound generation circuit that generates a sound corresponding to the scale of the key by pressing each key on the printed keyboard is output via a speaker such as a piezoelectric buzzer. A picture book type musical instrument toy consisting of is already known. However, in the case of this conventional musical instrument toy, there is a problem in that although the user can simply sing a song along with the performance sound, the singing voice cannot be mixed with the performance sound through the speaker. Further, in the case of a conventional musical instrument toy, the speaker is built in a casing that forms a keyboard-type sound generator attached to the picture book body, so the playing sound is muffled inside the casing, which reduces interest. There was a drawback of peeling.

In view of this, the present invention enables the singing voice to be placed on the same speaker in accordance with the performance sound generated by the keystrokes on the keyboard, and a speaker such as a piezoelectric buzzer can be placed upside down on the picture book body. A piano picture book with karaoke that can be set up so that you can learn how to play it and at the same time make you interested in singing, and you can make it louder than before without keeping the sound generated from the speaker The purpose is to do.

[0005]

[Means for Solving the Problems]

 The configuration of the present invention for achieving the above object will be described in detail. According to the first aspect of the present invention, by pressing each key of the printed keyboard on the folded picture book main body, In a picture book type musical instrument toy, a keyboard-type sound generator equipped with a sound generation circuit that generates a sound corresponding to the scale of A piano picture book with karaoke, characterized in that a microphone is provided in the sound generation circuit so that a singing voice is expanded from the speaker in accordance with a performance sound produced by keystrokes on a keyboard, and also according to claim 2. The invention is a piano picture book with karaoke according to claim 1, characterized in that the speaker is arranged upright in the picture book body.

【Example】

 Hereinafter, the concrete structure of the piano picture book with karaoke of the present invention will be described in detail based on the illustrated embodiment. FIG. 1 is a perspective view showing an embodiment of a piano picture book with karaoke of the present invention, FIG. 2 is a perspective view showing a speaker standing on the picture book body in the embodiment of FIG. 1, and FIG. 3 is an example of a sound generation circuit. FIG. 4 is a circuit diagram shown, FIG. 4 is an explanatory diagram when the speaker is erected, and FIG. 5 is an explanatory diagram when the microphone is stored in the keyboard-type sound generator.

In the figure, reference numeral 1 denotes a picture book main body composed of a front cover 2, a back cover 3 and a back cover 4, and the picture book main body 1 can fold the front cover 2 and the back cover 4 in half via the back cover 3. ing. Reference numeral 5 is a booklet attached to the inside of the cover 2 which is the main body of the picture book 1. The booklet 5 is printed with musical notes, lyrics, background images and other matters relating to the program.

Reference numeral 6 is a keyboard-type sound generator disposed inside the back cover 4 that constitutes the picture book body 1. The keyboard-type sound generator 6 is configured to generate a sound corresponding to the scale of the key by pressing each key on the printed and printed keyboard 7 through a speaker 8 such as a piezoelectric buzzer. That is, a switch group 9 is provided below the printed keyboard 7 as shown in FIG. 3, and when the desired keyboard 7 is pressed, the switch 9 therebelow is turned on and the piano IC 10 is switched on. The stored sound signal is output and amplified by the amplifier 11 to generate a sound of a predetermined scale from the speaker 8 composed of a piezoelectric buzzer or the like. It should be noted that the piano IC 10 can store a program for automatic performance, and in this case, the selected music can be automatically played by the speaker 8 by switching the select switch 12.

The sound generating circuit having the above-mentioned configuration is housed in a casing that constitutes the keyboard-type sound generator 6, and the casing is fixed to an appropriate place inside the folded picture book body 1 with an adhesive or the like. To be done. The speaker 8 made of a piezoelectric buzzer or the like in the sound generation circuit is provided outside the casing via a lead wire so that it can be inverted on the picture book body 1. That is, as shown in FIG. 4, the support plate 13 is pivotally attached to the back side of the speaker 8, and the lower end portion of the support plate 13 is raised by the stopper 14 projecting from the picture book body 1 after the speaker 8 is erected. It is something that you try to suppress. It is preferable that the support plate 13 is provided with a notch 15 so that the stopper 14 protruding from the picture book body 1 when the speaker 8 is folded can be accommodated in the notch 15.

Next, reference numeral 16 denotes a microphone attached to the sound generating circuit forming the keyboard-type sound generator 6, and the microphone 16 is connected via a cord 17 as shown in FIGS. 1 and 2. It is built into the sound generation circuit. The sound signal input from the microphone 16 is amplified by the amplifier 11 as shown in FIG. 3, and is emitted as a loud sound from the speaker 8 that emits a performance sound. In order to store the microphone 16 compactly when not in use, on the back side of the casing forming the keyboard-type sound generator 6, as shown in FIG. ing. In addition, the cord 17 of the microphone 16 may be appropriately bundled by using a cord stop band 20.

The piano picture book with karaoke according to the present invention has the above-mentioned structure. When the piano performance is to be enjoyed, the picture book body 1 is opened as shown in FIG. 1, and then the speaker 8 is raised as shown in FIG. By switching the select switch 12 of the keyboard type sound generator 6 to the playing mode and pressing the printed keyboard 7, a sound corresponding to the scale of the keyboard 7 is generated from the speaker 8. At the same time, when a voice is input from the microphone 16, the voice and the performance sound are mixed and emitted together from the speaker 8. Therefore, it is possible to sing the lyrics of the song at the same time according to the performance of the piano, and it becomes a very hobby piano picture book. If a program for automatic performance is stored in the piano IC 10 in the sound generation circuit, the selected song can be automatically played by the speaker 8 by switching the select switch 12. It is also possible to input a voice from the microphone 16 as the accompaniment sound.
