DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical scale learning apparatus capable of directly listening to the musical scale of a musical note specified on a musical score and learning the correspondence between musical scores and musical intervals.

[0002]

2. Description of the Related Art It is not easy to read musical scores and directly understand the melody of a musical composition. Even adults who can read musical scores and play musical instruments may not always be able to imagine the melody line of a musical composition from the first musical score. However, if the ability to directly read the melody line of the music from the note sequence on the musical score can be acquired, the interest and motivation for the music will be doubled, and the performance ability of the musical instrument will be greatly enhanced. Therefore, it is desired to provide children and infants with appropriate training so as to feed the absolute scale and acquire the ability to read musical scores, and various electronic musical instruments intended for such training have been developed.

[0003] JP-A-54-143346, JP-A-57-146284 and JP-A-60-988.
Japanese Patent Application Publication No. 99-1992 discloses an apparatus that superimposes a musical score on a scale designation switch board connected to an electronic musical instrument and presses a switch arranged at a note position to reproduce an electronic sound corresponding to the musical note scale. The operator plays the melody by pressing notes on the musical score in order from the beginning of the music, and checks the pitch of the reproduced sound corresponding to the position on the staff. And
If only the musical score is exchanged without changing the scale designating switch board, the same reproduction and learning can be performed for other various songs.

[0004] Further, French Patent No. 1 564 745 discloses an apparatus for designating the scale of a reproduced sound by making electrical contact with a staff-like wiring pattern connected to an electronic musical instrument. In this apparatus, an exchangeable score sheet having holes at note positions is superimposed on a substrate on which wiring patterns of the number of musical scales arranged in parallel with the staff are formed. Then, when the user touches the wiring pattern through the hole in the score using the electrode rod held by the user, a scale designation signal is input to the electronic circuit through the wiring pattern, and an output signal of the designated scale frequency is output from the electronic circuit to drive the speaker. I do.

[0005]

Problems to be Solved by the Invention
All of the devices disclosed in Japanese Patent Publication No. 46-46 and the like are composed of "a common switchboard + interchangeable musical score", and therefore it is necessary to accurately position the musical score and the switchboard prior to performance. Since the common switchboard is equivalent to a key extended long along the staff, if the height of the switchboard and the staff on the musical score deviate, the wrong scale note will be reproduced. Therefore, the preparation for the performance including the positioning of the musical score and the switchboard is troublesome, and the infant and the young cannot prepare for the performance alone. Further, due to the difficulty in positioning, it is not possible to use a musical score with a narrow staff interval, and the positioning may be shifted due to expansion and contraction of the musical score due to humidity, bending or abrasion of the sides of the musical score, wrinkles of the musical score, and the like.

[0006] Further, since the scale is specified by the switch board with reference to the notes on the score, even if the score and the switch board are accurately positioned, if the position deviating from the notes on the score is manipulated during the performance, it is natural. , A scale note unrelated to the note is reproduced. At this time, if the user does not notice that the user has operated a position off the note, the pitch of the note is incorrectly learned. In other words, since the melody can be created without accurately following the note sequence on the musical score, the concentration on the musical note on the musical score is easily interrupted, and the learning effect of associating the musical note with the scale does not increase.

On the other hand, French Patent No. 156474
In the device shown in No. 5, since an electric signal is inputted to the wiring pattern through the through hole formed in the musical score, there is no need to contact an area other than the through hole to reproduce an incorrect melody. However, a common wiring pattern is used for a large number of musical scores, and the same wiring pattern is always used even when the musical scores are exchanged. Therefore, similar to the apparatus disclosed in Japanese Patent Application Laid-Open No. 54-143346, the wiring pattern is On the other hand, it is impossible to avoid the difficulty of precisely positioning the score. In the case of a wiring pattern common to many scores, many wiring patterns are arranged in parallel with the staff notation, and a maximum of three wiring patterns are arranged between the wiring patterns of two lines of the staff. Due to restrictions, it is difficult to design a simple system in which the interval between musical staffs is reduced. Also, in individual songs, the scale of the semitone keys is used less frequently, and the scale of the whole key not used throughout the score is not small, but a wiring pattern common to many scores corresponds to these scales. Wiring patterns also need to be treated in the same way as wiring patterns corresponding to musical scales that appear frequently on musical scores. Therefore, the number and density of the wiring patterns increase, and the manufacturing cost increases.

By the way, since nursery rhymes for infants are generally short, it is desirable to increase the interval between staffs and increase the note area on the premise of operation by infants. On the other hand, for long and complicated music such as movie music, it is desirable that the staff interval can be reduced so that long music can be played on one sheet of music, assuming operation by a person who has some skill. However, with a common wiring pattern for many scores, both short songs for infants and long songs for masters use music in which staffs of the same interval and length are arranged at the same interval, and operability is improved. Is impaired, the restrictions on product design are increased, and the cost of wiring patterns and musical scores is increased. And saying,
If the system replaces two or three types of wiring patterns having different staff intervals according to the score to be used, the practicability and operability of the musical scale learning device with respect to the replacement of the wiring patterns are further reduced, and the score and the wiring patterns are changed. There is also a possibility that the correspondence is wrong.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a musical scale learning apparatus that does not require positioning of a musical score and a wiring pattern when exchanging musical scores, and that can use a staff with an optimal pitch according to the size of a musical score sheet and the length of a music piece. And

[0010]

According to a first aspect of the present invention, there is provided a scale learning apparatus for outputting a scale note of a musical note when the musical note on the musical score comes into contact with the musical note.

[0017]

According to the first aspect of the present invention, a reproducing apparatus for generating a scale sound in accordance with a scale command signal and a musical score unit exchanged in accordance with a musical piece to be played are connected via a first connector and a second connector. Can be detachably combined. A score unit from which the score content can be read from the front side includes a wiring pattern which is pre-positioned and integrally fixed to the score.

In the musical scale learning device according to the second aspect, the guided structure (contour, convex portion, hole, etc.) on the musical score unit side is positioned in the detachable guide structure (slide guide, insertion pin, etc.) of the reproducing device, thereby reproducing the music. The first connector member of the musical score unit is automatically positioned on the second connector member of the apparatus.

In the score unit according to the third aspect, a through-hole is formed in the surface member corresponding to a note on the score. An operator operates a conductive needle or rod to supply an electric signal (power supply voltage, ground potential, AC signal, noise, etc.) to one wiring pattern through the through hole. The electrical signal is a scale designation signal that is distinguished from the input to other wiring patterns.
The signal is transmitted from the wiring pattern to the electronic circuit of the reproducing circuit via the first connector and the second connector.

According to the musical score unit of the fourth aspect, the electric signal supplied to the contact pad member flows into the wiring pattern through the through hole. The peripheral portion of the contact pad member insulated by the surface member can supply an electric signal to the wiring pattern in a range wider than the area of the through hole, and can be expanded to a position where the wiring pattern overlaps an adjacent wiring pattern in a planar manner.

In the score unit of the present invention, the degree of freedom in designing a wiring pattern is enhanced by utilizing the fact that a unique wiring pattern can be used for each score. As mentioned above, 1
Since the number of scales used on a musical score of a music piece is limited, wiring patterns of unnecessary scales are not provided, and wiring patterns of necessary scales are arranged outside the space. Further, at positions other than the notes to be communicated, the positional relationship with the staff may be ignored. In addition, a through hole may be formed at a position off the center of the note as long as it is within the range of the contact pad member. For example, in the case where notes of three adjacent scales appearing in semitone difference successively on the score, the through holes at both ends are shifted outward within the range of the note area, and the corresponding wiring patterns at both ends are shifted outward. Ensure the line width and separation interval of the central wiring pattern.

In the musical score unit of the present invention, the wiring patterns insulated from each other are superimposed on two or three layers and three-dimensionally crossed to increase the degree of freedom of the wiring patterns on each layer. For example,
Musical notes of frequently used scales on musical scores are communicated by wiring patterns in the direction along the staff, while musical notes of musical scales that appear only several times on musical scores are printed using wiring patterns that jump other wiring patterns. Contact the first connector directly.

In the score unit of the present invention, an operator presses a switch structure provided for each note on the score to generate a scale designation signal. When the conductive rubber member and the wiring pattern are brought into conduction according to the operation, an electric signal flows from the electrode member to the wiring pattern.

In FIG. 1, the musical score unit 30 is attached to the reproducing apparatus 10 by inserting the male connector 31 into the female connector 20 while being placed on the bed 11. The height of the bed 11 is determined so that the heights of the male connector 31 and the female connector 20 are the same, and the wall portions 24 rising on both sides are
The male connector 31 is positioned relative to the female connector 20 in the width direction by loosely restraining the edges on both sides of the musical score unit 30. The operator operates the contact rod 21 connected to the reproducing apparatus through the wiring 23 on the musical score unit 30 to generate a scale designation signal. The scale designation signal is the male connector 3
1 and the female connector 20 are input to the playback device 10. The head 12 of the playback device 10 stores the speaker 13 and the electronic circuit (25) shown in FIG. 2, and generates a playback sound according to the scale designation signal.

On the upper surface of the head 12, a power switch 1
6, an ON / OFF display lamp 17, a keyboard picture 14, a display lamp 15 corresponding to a key on the keyboard, a rhythm type setting switch 18, and a rhythm speed setting switch 19 are arranged. The playback device 10 generates a playback sound according to the scale designation signal, and at the same time, displays the display lamp 15 of the corresponding keyboard key.
Is turned on one. The reproduction device 10 also generates a rhythm of the type selected by the setting switch 18 at a speed selected by the setting switch 19 in order to perform rhythm guidance when operating the contact rod 21 on the musical score unit 30.

As shown in FIG. 2, the ends of a plurality of wiring patterns 32 formed on the musical score unit 30 are connected to the contacts of the male connector 31, respectively. The female connector 20 of the playback device 10 has 23 pins corresponding to each of two octaves and 23 scales (including chromatic scales), and inputs 23 different scale designation signals to the electronic circuit 25. Electronic circuit 2
5 generates an electric signal having a frequency corresponding to the scale designation signal, synthesizes the electric signal with the electric signal of the rhythm sound selected by the setting switches 18 and 19, and activates the speaker 13. Electric power is supplied to the electronic circuit 25 from the dry battery 26 via the power switch 16. Each wiring pattern 32
Are connected to the power supply potential via a resistor (not shown) in the electronic circuit 25. on the other hand,
The pin 22 of the contact rod 21 is connected to the ground potential of the electronic circuit 25. Therefore, when the pins 22 of the contact rods 21 are brought into contact with the circuit pattern 32 suspended at the power supply potential, the potential of one wiring pattern 32 decreases to the ground potential, and the musical scale designation signal corresponding to the wiring pattern 32 is generated. Input to the electronic circuit 25.

As shown in FIG. 3, the circuit pattern 32 is silk-screen printed on the substrate sheet 36 of the musical score unit 30 using conductive ink. Substrate sheet 36
The score is printed in advance on the surface of the insulating sheet 35 bonded to the sheet, and a large number of through holes 38 are formed corresponding to all the notes on the score. Contact pads 37 that cover the area of each note ball on the score and conduct to the wiring pattern 32
Is formed by positioning the insulating sheet 35 on the substrate sheet 36 and then performing silk screen printing using a conductive pigment from the front side of the insulating sheet 35.

As shown in FIG. 4, the plurality of wiring patterns 32 on the substrate sheet 36 basically have a Z
Connect all notes belonging to the same scale back and forth in a letter shape along a staff notation. However, for example, as shown in FIG. 3, there is no circuit pattern 32 of the A scale (ra tone) which is never used on the score, and by using the saved space,
The width, interval, and arrangement of the wiring patterns 32A and 32B of the adjacent G scale (sound) and B scale (sound) have a margin. Then, the wiring pattern 32A and the contact pad 3
The through-hole 38 for ensuring the conduction of No. 7 is provided at a position off the center of the musical note in conformity with the shifted wiring pattern 32A. As shown in FIG. 4, a wiring pattern 32 </ b> C that is directly connected to the male connector 31 across the staff notation is provided for a musical note of a scale that is not frequently used on a musical score. The wiring pattern 32C is formed by affixing a copper-coated resin tape to the back surface of the substrate sheet 36, and is connected to musical notes and terminals on the front surface by eyelets. Further, as shown in FIGS. 1 and 2, the male connector 31 of the musical score unit 30 is provided.
The number of pins is reduced from the number of pins of the female connector 20 by thinning out pins of musical scales that are never used on the score.

In the musical scale learning device configured as described above,
When the operator grips the contact rod 21 and brings the pin 22 into contact with the contact pad 37 on the musical score, the musical scale of the musical note is output from the speaker 13. The operator touches the pin 22 following the note in order from the beginning of the score to reproduce the melody line of the score. At this time, the contact pad 37 (note)
When the pin 22 is brought into contact with a position out of the way, no sound is produced. Therefore, the operator carefully aims at the note on the score, and understands the position of the note by associating it with the staff without distracting from the score. While learning the scale of notes.

If the relationship of the pin arrangement of the male connector 31 with respect to the pin arrangement of the female connector 20 can be ensured, the wiring pattern 32 itself can be designed freely according to the music. Therefore, it is possible to set the length and interval of the musical notation of the musical score by making the most of the area of the musical score unit 30, and to provide an easy-to-use scale learning device excellent in design. For example, if you use a common wiring pattern for multiple scores,
If the line width is 1 mm and the interval is 1 mm, the staff width is 2 mm
× 4 (number of semitones) × 4 (segment) = 32 mm, but in this embodiment using a unique wiring pattern, unnecessary wiring patterns are removed to adjust the wiring interval, so that The width is 2mm x 2 (number of semitones) x 4 (score) = 16
mm. In addition, since the contact pads 37 are provided to enable electrical contact in a range where the area of the note is full, there is no case where no sound is produced even when the note is touched. The musical notes can be made large according to the staff notation, and the aesthetic appearance of the musical score and the operability of the scale learning device can be improved. Further, since the musical score unit 30 is positioned by the bed 11 and the wall portion 24, and the male connector 31 and the female connector 20 can be easily connected when the musical score unit 30 is replaced, even the infant can easily replace the musical score unit 30. Then, you can select the songs on your own.

In the embodiment, a structure similar to a normal printed circuit board connector is employed as a connection structure between the musical score unit 30 and the reproducing apparatus 10. However, as shown in FIG. 5, a laminated rubber connector is used. (A so-called zebra connector) may be employed. Rubber connector 4
Reference numeral 4 denotes a clip-like structure which is spring-biased against the rubber substrate 40, opens a gap between the rubber connector 44 and the rubber substrate 40 against the spring force, and connects the terminal portion of the musical score unit 43 to the gap. Insert 42. Rubber connector 44
Are a thin plate 46 of conductive rubber and a thin plate 45 of insulating rubber.

Deformed in accordance with the unevenness of the terminal portion 42 to ensure reliable conduction between the wiring 41 and the terminal portion 42.

Further, in the embodiment, the pitch designation signal is generated by bringing the pin 22 of the ground potential into contact with the contact pad 37 of the musical note, but an AC voltage or a noise signal is transmitted to the wiring pattern 32 through the pin 22. It may be configured. In the case of utilizing radio waves in the air or noise signals of the human body, a wiring 2 connecting the pin 22 of the contact rod 21 and the reproducing device 10
3 becomes unnecessary.

Further, in the embodiment, the electric signal is directly inputted to the wiring pattern 32 from the outside of the musical score unit 30, but an individual switch structure as shown in FIG. 6 may be provided for all the notes. . A wiring pattern 52 similar to that of the embodiment is formed on the surface of a substrate sheet 51, and a through hole 56 corresponding to a musical note is formed on an insulating surface sheet 53 to which a conductive film 54 is attached. The conductive rubber pad 57 connected to the conductive film 54 forms a push switch structure for controlling conduction / cutoff between the wiring pattern 52 and the conductive film 54.
When the surface of the conductive rubber pad 57 is pressed, the conductive rubber pad 57 contacts the wiring pattern 52 in the space inside the through hole 56,
An electric signal on the conductive film 54 side inputs a scale designation signal to an electronic circuit (not shown) through the wiring pattern 52.

In the embodiment, the number of pins corresponding to the number of musical scales to be used is secured for the male connector 31 of the musical score unit 30 and the female connector 20 of the playback device 10, respectively. The playback device 10 may decode the binary code or the gray code to determine the scale designation signal. As a result, the number of connector pins required for transmitting the scale designation signal of the required scale is greatly reduced. In the embodiment, the wiring pattern 32 is printed and formed using conductive ink on the surface of the substrate sheet 36 made of cardboard or the like, but the wiring pattern is formed by etching a thin resin film to which an aluminum foil is attached. Then, such a resin film with a wiring pattern may be laminated in two or three layers and fixed on a mount.

[0036]

According to the first aspect of the present invention, since the musical score and the wiring pattern are combined into a musical score unit and can be exchanged integrally with the reproducing apparatus, various musical pieces can be played by exchanging the musical score unit. . In addition, since the musical score and the wiring pattern are integrated, there is no need to position the musical score and the wiring pattern when changing music, and there is no fear of malfunction or erroneous performance due to poor positioning.

According to the second aspect of the present invention, when the musical score unit is positioned in the reproducing apparatus, the positioning of the first connector member and the second connector member is automatically completed, and a reliable connection between the two can be easily secured. . Therefore, even a toddler or a beginner who lacks electrical knowledge can freely exchange the musical score unit.

According to the third aspect of the present invention, a unique wiring pattern can be adopted according to the convenience of the musical score. Therefore, the width of the staff is adjusted by adjusting the wiring pattern in accordance with the length of the music and the scale usage in the music. The number of steps and the number of steps can be set freely, and a score unit excellent in design and operability can be provided. Also,
Restrictions on the density and accuracy of the wiring pattern can be relaxed, and an inexpensive and easy method such as silk screen printing can be employed for forming the wiring pattern. In addition, unlike a device that uses a common switch board for many scores and allows only the score to be exchanged, no matter where you operate on the score, no sound is output. Since the sound is output only after this, the concentration of the operator on the musical score is not interrupted, and no wrong sound is learned. Therefore, it is possible to efficiently execute the scale learning for cultivating the pitch and the learning for reading the score and reproducing the melody line.

According to the fourth aspect of the present invention, the musical scale designation signal can be inputted to the wiring pattern even from the outside of the wiring pattern within the area range of the contact pad, so that the operation reliability and the operability of the device are improved. You. Further, a wiring pattern can be designed regardless of the area of the contact pad.

According to the fifth aspect of the present invention, the number of wiring patterns formed in the musical score unit is reduced, and the degree of freedom in line width, spacing, and arrangement with respect to necessary wiring patterns is increased. For example, when a long and complicated music piece is combined into one sheet music unit using a narrow, high-density staff notation, a large line width and interval of the wiring pattern can be secured, and the degree of freedom in selecting a manufacturing method increases. Manufacturing accuracy is low. Therefore,
Necessary wiring patterns can be formed inexpensively and with high yield.

According to the sixth aspect of the present invention, it is possible to rationalize the wiring pattern three-dimensionally and to secure a large line width and interval of the frequently used musical scale musical pattern.

According to the seventh aspect of the present invention, it is possible to use a musical score unit (switch board) in which the number of wiring patterns and the number of switches are optimized by optimizing each musical score. Equipment can be provided.
