Solenoids 3-1 to 3-3 of solenoid group 4
As a representative of one of them, n is fixed to a mounting plate 14 below the key 1-1 as shown in the longitudinal sectional view of FIG. 2, and vertically moved to the inner cylinder of this solenoid 3-1. The plunger 15 pierced as possible penetrates the key 1-1 from the lower side to the upper side at the upper end, and is fixed to the upper surface of the key 1-1 by the collar 50.

One end of the key 1-1 is supported by the support shaft 16 so as to be rotatable by a predetermined angle, and is biased in the upper direction by a spring 17 disposed on the lower surface side near the support shaft 16, Further, the other end is supported by the stopper plate 24 in the position shown by the solid line in the standby state because the displacement in the upward direction is restricted. This key 1-1 is provided with two protruding pieces 18 and 19 of different lengths that are adjacent to each other in order to detect the speed of key depression and change the rising characteristics of the musical sound. Two switch parts 20 and 21 are arranged facing each other at a predetermined distance below the tips of the pieces 18 and 19, and the first projecting piece 18 presses the first switch part 20 by a key pressing operation with a finger 22. The key pressing speed can be detected by the time difference from the timing when the second protrusion 19 presses the second switch portion 21.

In the CPU 6, the first protruding piece 18 is the first
It is configured to detect which key is pressed by a signal when the switch unit 20 is pressed.

On the other hand, the driver circuit 5 for exciting the solenoid 3-1 includes the solenoids 3-1 to 3-3 of the solenoid group 4.
-Transistor 5 for inputting exciting current to each n
1 to 5-n, a DA converter 5A for converting the attraction force data PD indicating the attraction force of the plunger of the solenoid to be excited into an excitation signal of a corresponding amplitude level, and this DA converter 5
And a multiplexer 5B that selectively outputs the excitation signal output from A to the base inputs of the transistors (5-1 to 5-n) corresponding to the target solenoid,
The transistors 5-1 to 5-n current-amplify the excitation signals input from the multiplexer 5B and apply the amplified signals as excitation currents to the corresponding solenoids 3-1 to 3-n. The multiplexer 5B determines the distribution destination of the excitation signal based on the pitch data KN of the key to be pressed. Then, the pitch data KN and the suction force data PD indicating the suction force of the plunger form a set of drive data corresponding to each key to be pressed, are input from the CPU 6 for each key, and are synchronized with the pressing timing. And then input.

On the other hand, the ROM 8 stores in advance programs and various data required for tone generation, but in addition to this, as information for performing automatic performance or performance practice, the information is sequentially stored as the desired music progresses. Pitch data KN indicating the pitch of the musical tone corresponding to the key to be pressed, tone length data LD indicating the length of the musical tone (including rest length), and solenoid 3 for generating the musical tone 3- The attraction force data PD indicating the attraction force of the plungers 1 to 3-n is one set, and the required number of sets are stored in the order of progression of the music.

Incidentally, these pitch data and the like are not stored in the ROM 8 but stored in a cassette type memory card and read out when necessary, or when a rewritable memory is provided and necessary. Various known data holding methods can be used, such as writing and using pitch data of a desired music piece.

Next, the operation of the above configuration will be described with reference to the flow charts of FIGS.

First, the electronic musical instrument having the above-mentioned structure automatically presses the keys 1-1 to 1-n by the solenoid group 4 based on the data stored in the ROM 8 to generate a musical tone corresponding to the pressed key. There are an automatic performance mode and a navigation performance mode for practicing a performance operation of a desired music.

FIG. 3 is a flow chart showing the operation in the automatic performance mode. When the automatic performance mode is selected by the mode selection operation of the mode selection switch section 7 and the start of the automatic performance is instructed, the CPU 6 stores the ROM 8 in advance. The pitch data KN, the pitch length data LD, and the attraction force data PD of the stored music for automatic performance are read one by one (step 30), and the pitch data KN and the attraction force data PD are stored in the driver circuit 5. input.

When the attraction force data PD is input, the DA converter 5A of the driver circuit 5 converts the data PD into an analog excitation signal having a corresponding amplitude level, and inputs the analog excitation signal to the multiplexer 5B. The multiplexer 5B uses the input analog excitation signal as the base of the transistors (5-1 to 5-n) corresponding to the target key (1-1 to 1-n) according to the pitch data KN input from the CPU 6. to deliver.

For example, assuming that an excitation signal is input to the base of the transistor 5-1, this excitation signal is amplified by the transistor 5-1 and becomes an excitation current, which results in an excitation current. Applied to. As a result, the solenoid 3-1 is excited, and the plunger 15 arranged in the inner cylinder of the solenoid 3-1 so as to be movable up and down is attracted. With this, the key 1-1 is pulled down. The pulling force in this case depends on the suction force data PD, but the suction force data PD in the automatic performance mode is selected to be a value that produces a sound at the same volume as when the finger 22 is pressed.

Therefore, the key 1-corresponding to the pitch data KN
By exciting the solenoid 3-1 of No. 1 with an exciting current having a magnitude corresponding to the attraction force data PD, the plunger 15 movable up and down in the solenoid 3-1 presses the key 1-1 with the finger 22. The key 1-1 is pulled at the same speed as in step 1 to bring the key 1-1 into the depressed state (step 31).

When the key 1-1 is depressed, the solenoid 3-
Of the two projecting pieces 18, 19 provided in the vicinity of the support shaft 16 of the key 1-1 by the plunger 15 of No. 1, the projecting piece 18 having the longer length in the hanging direction is first arranged at the opposing position. Since the first switch portion 20 present is pressed, and then the other short protruding piece 19 presses the switch portion 21 arranged at the opposite position, the CPU 6 causes the protruding piece 18 to press the switch portion 20. It is recognized that the pressed key is the key 1-1 based on the time signal. At the same time, the key pressing speed, that is, the touch response data TD, together with the pitch data KN of the key pressing key 1-1, is generated by the musical tone generating circuit 10 due to the time difference between the protruding pieces 18 and the protruding pieces 19 sequentially pressing the facing switch parts 20, 21. And the timing signal KON is further transferred to instruct the start of sound generation (step 32).

The tone generation circuit 10 generates tone waveform data of a tone pitch corresponding to the inputted tone pitch data KN, and further uses the envelope waveform generated for the tone waveform data in synchronization with the timing signal KON. Amplitude control is performed. Further, the amplitude is also controlled by the touch response data TD, and then input to the DA converter 11. The DA converter 11 converts the inputted musical tone waveform data into an analog musical tone signal having a corresponding amplitude level, amplifies it by the amplifier 12, and then causes the speaker 13 to generate a musical tone.

While the musical tone generating circuit 10 is generating musical tone waveform data in this way, the CPU 6 carries out various other processes such as whether or not the preselected tone color has been changed (step 33). After this, it is judged from the tone length data LD read from the ROM 8 at the same time as the tone pitch data KN whether or not the tone generation time after the generation of the timing signal KON has reached the time indicated by the tone length data LD (step 34). If not reached, the processes of step 33 and step 34 are repeated until reached. However, if the tone generation time has reached the time indicated by the tone length data LD, the read address to the ROM 8 in order to read the tone pitch data KN, tone length data LD, and suction force data PD of the next pressed key from the ROM 8. Is updated (step 35). After this,
The CPU 6 determines whether or not the last musical tone of the music has been sounded (step 36), and if the musical tone generation ends, the musical tone generating operation in the automatic performance mode ends. However, if there are musical tones that have not been pronounced yet, step 36
Then, the procedure returns to step 30, and the musical tone generating circuit 10 is caused to similarly generate the musical tone waveform data to be generated next.

Next, the operation of the navigate performance mode will be described with reference to the flow chart shown in FIG.

First, the navigation performance mode is selected by using the mode selection switch section 7 and the start of the navigation performance is instructed.

Then, the CPU 6 reads the pitch data KN for navigation performance stored in the ROM 8 in advance in the same manner as in the automatic performance mode, and inputs the pitch data KN and the attraction force data PD to the driver circuit 5. (Step 40).

The DA converter 5 A driver circuit 5 converts the attraction data PD in the same manner as the automatic performance mode to the analog excitation signal of the corresponding amplitude level, the multiplexer 5
Target solenoid, eg solenoid 3 via B
-1 is input to the base of the transistor 5-1 to which it is connected, so that the plunger 15 of the solenoid 3-1
Is sucked (step 41).

At this time, the attraction force data PD in the navigate performance mode is about half the value in the automatic performance mode. This may be a method in which the CPU 6 changes the attraction force data having the same value as in the automatic performance mode to a half size.
A method of storing the suction force data of a certain size may be used.

If the size of the suction force data PD is reduced to about 1/2 of that in the automatic performance mode, the plunger 1
Since the suction force by 5 is also reduced to about 1/2, the plunger 15 cannot pull the key 1-1 to the same depth as in the automatic performance mode. For this reason, the key 1-1 can be pulled only up to about 1/2 of the pushable depth as shown by the broken line 23 in FIG. 2, and the two projecting pieces 18, 19 press the switch portions 20, 21. half pressed under conditions are created to stop in front.

[0033] Of this time, only the keys 1-1 are pressed to the half pressing under conditions, the key adjacent thereto for not pressed a key to key 1-1 semi pressed state is then pressed As a result, the practitioner can be visually recognized.

Then, when the practitioner who recognizes that the half-pressed key 1-1 is the key to be pressed next, when the practitioner presses the key 1-1, the switch piece 20 is pressed by the protruding piece 18 for the first time. Accordingly, the CPU 6 detects that the half-depressed key 1-1 is depressed in the same manner as the normal performance (step 42).

Thereafter, as in the case of the automatic performance mode, the touch response data corresponding to the time difference between the switching time of the first switch section 20 and the switching time of the second switch section 21 is pressed. In addition to the tone pitch data 1-1, it is transferred to the tone generation circuit 10 and the timing signal KON is further transferred to instruct the start of sound generation (step 43).

Then, the musical tone generating circuit 10 generates musical tone waveform data of a tone pitch corresponding to the inputted tone pitch data KN, and further, the timing KO for the tone waveform data.
Amplitude control is performed by the envelope waveform generated in synchronization with N. Further, the amplitude is also controlled by the touch response data TD, and then input to the DA converter 11. D
The A converter 11 converts the inputted musical tone waveform data into an analog musical tone signal of a corresponding amplitude level, amplifies it by the amplifier 12, and then causes the speaker 13 to generate a musical tone.

While the musical tone generating circuit 10 is generating musical tone waveform data in this way, the CPU 6 carries out various other processes such as whether or not the preselected tone color has been changed (step 44). After this, similarly to the pitch data KN, it is judged from the pitch length data LD read from the ROM 8 whether or not the tone generation time after the generation of the timing signal KON has reached the time indicated by the pitch length data LD (step 45). If not, go to step 4
4, the process of step 45 is repeated. However, if the pronunciation time has reached the time indicated by the tone length data LD,
The read address to the ROM 8 is updated in order to read the tone pitch data KN, tone length data LD, and suction force data PD of the next pressed key from the ROM 8 (step 46). After this, CP
U6 determines whether or not the last tone of the music has been sounded (step 47), and if it ends, the tone generation operation in the automatic performance mode ends. However, if there is still a tone that has not been sounded, the process returns from step 47 to step 40, and similarly, the tone generating circuit 10 is caused to generate the tone waveform data to be generated next.

As described above, in the navigate performance mode,
Since the practitioner is taught by putting the key to be pressed next in the half-pressed state, the practitioner visually knows which key to press next, and then actually uses his or her finger 22. The pitch of the pressed key can be known from the pitch of the musical sound produced when the key is pressed. Therefore, the key depression position and scale can be learned not only by the sense of sight but also by the sense of touch and the sense of hearing, so that the practice effect of the musical instrument is dramatically improved.

By the way, in the above-mentioned embodiment, when a half-pressed key is depressed, a musical tone is electronically generated in response to the key depression operation. However, the present invention is not limited to this.
It can also be applied to a natural musical instrument that actually vibrates a sounding body such as a string in response to a key depression operation of a half-depressed key.

FIG. 5 shows a key 1 when the present invention is applied to an acoustic piano which is a kind of such a natural musical instrument.
It is a longitudinal cross-sectional view of -1.

[0041] That is, in this embodiment, a strut 26 is erected on the support plate 25, after having mounted the hammer arm 28 rotatably supporting shaft 27 of the tip of the struts 26, half-pressing under indicated by the broken line 23 When the player presses a key in this state, the protrusion 29 on the back surface of the hammer arm 28 is pushed up by the end of the key 1-1, so that the hammer 37 striking the string 39 is moved by the inertial force of the weight 38 in the hammer arm 28. Is used to rotate clockwise to strike the string 39, and after striking the string, the hammer arm 28 and the weight 38 built in the arm 28 restore the original position. The key 1-1 is configured so that it can be driven into a half-depressed state by the plunger 15 of the solenoid 3-1 as in FIG. These means constitute a musical tone generating means for actually striking the string 39 to generate a musical tone, and the musical tone generating means constitutes the musical tone generating means of the above-described embodiment, the musical tone generating circuit 10 and the DA converter 1.
1, the amplifier 12 and the speaker 13 are provided instead.

Also in this structure, the same effect as that of the embodiment of FIG. 1 can be obtained. That is, in this key structure, CP
U6 performs an automatic performance operation and a navigation performance operation based on the flowcharts shown in FIGS. In addition,
In these flowcharts, steps for performing the same processing as those in FIGS. 3 and 4 are represented by the same symbols.

FIG. 6 is a flow chart showing the operation in the automatic performance mode. When the automatic performance mode is selected by the mode selection operation of the mode selection switch section 7 and the start of the automatic performance is instructed, the CPU 6 stores the ROM 8 in advance. The pitch data KN, the pitch length data LD, and the attraction force data PD of the stored music for automatic performance are read one by one (step 30), and the pitch data KN and the attraction force data PD are stored in the driver circuit 5. input.

When the attraction force data PD is input, the DA converter 5A of the driver circuit 5 converts the data PD into an analog excitation signal having a corresponding amplitude level, and inputs the analog excitation signal to the multiplexer 5B. The multiplexer 5B uses the input analog excitation signal as the base of the transistors (5-1 to 5-n) corresponding to the target key (1-1 to 1-n) according to the pitch data KN input from the CPU 6. to deliver.

For example, assuming that an excitation signal is input to the base of the transistor 5-1, this excitation signal is amplified by the transistor 5-1 and becomes an excitation current, so that the solenoid 3-1 of the solenoid group 4 is obtained. Applied to. As a result, the solenoid 3-1 is excited, and the plunger 15 arranged in the inner cylinder of the solenoid 3-1 so as to be movable up and down is attracted. With this, the key 1-1 is pulled down. The pulling force in this case depends on the suction force data PD, but the suction force data PD in the automatic performance mode is selected to be a value that produces a sound at the same volume as when the finger 22 is pressed.

Therefore, the key 1-corresponding to the pitch data KN
By exciting the solenoid 3-1 of No. 1 with an exciting current having a magnitude corresponding to the attraction force data PD, the plunger 15 movable up and down in the solenoid 3-1 presses the key 1-1 with the finger 22. The key 1-1 is pulled at the same speed as in step 1 to bring the key 1-1 into the depressed state (step 31).

When the key 1-1 is pushed down, the end of the key 1-1 pushes up the protrusion 29 on the back surface of the hammer arm 28, so that the hammer 37 striking the string 39 is moved to the inertia of the weight 38 in the hammer arm 28. Rotate clockwise using force. As a result, the string 39 is struck, and a musical tone with a pitch corresponding to the natural frequency of the string 39 and a volume corresponding to the striking force of the hammer 37 is produced. After striking the strings, the key 1-1 is returned to its original position by the hammer arm 28 and the weight 38 incorporated in the arm 28.

While the musical tone is being generated in this way, the CPU 6 performs various other processes such as whether or not the preselected tone color has been changed (step 3).
3) After that, it is judged from the pitch length data LD read from the ROM 8 simultaneously with the pitch data KN whether or not the sounding time after driving the key 1-1 has reached the time indicated by the pitch length data LD. (Step 34) If not reached, the processes of Step 33 and Step 34 are repeated until reached. However, if the pronunciation time has reached the time indicated by the tone length data LD, the pitch data KN,
The read address to the ROM 8 is updated to read the sound length data LD and the suction force data PD from the ROM 8 (step 35). After that, the CPU 6 determines whether or not the last musical sound of the music has been sounded (step 36), and if the musical sound generation is completed, the musical sound generating operation in the automatic performance mode is ended. However, if there is a tone that has not been sounded yet, the process returns from step 36 to step 30.

Next, the operation of the navigate performance mode will be described with reference to the flowchart shown in FIG.

First, the navigation performance mode is selected using the mode selection switch section 7 and the start of the navigation performance is instructed.

Then, the CPU 6 reads out the pitch data KN for navigation performance stored in the ROM 8 in advance as in the automatic performance mode, and inputs the pitch data KN and the attraction force data PD to the driver circuit 5. (Step 40).

[0052] DA converter 5 A driver circuit 5 converts the attraction data PD in the same manner as the automatic performance mode to the analog excitation signal of the corresponding amplitude level, the multiplexer 5
Target solenoid, eg solenoid 3 via B
-1 is input to the base of the transistor 5-1 to which it is connected, so that the plunger 15 of the solenoid 3-1
Is sucked (step 41).

At this time, the attraction force data PD in the navigate performance mode is about half the value in the automatic performance mode.

If the size of the suction force data PD is reduced to about 1/2 of that in the automatic performance mode, the plunger 1
Since the suction force by 5 is also reduced to about 1/2, the plunger 15 cannot pull the key 1-1 to the same depth as in the automatic performance mode. Therefore, the key 1-1 is pulled only to about 1/2 of the depth at which it can be pressed, as shown by the broken line 23 in FIG. 5, and the displacement is such that the hammer arm 28 cannot be rotated clockwise. semi press under like <br/> condition is created to stop in the state.

[0055] Of this time, only the keys 1-1 are pressed to the half pressing under conditions, the key adjacent thereto for not pressed a key to key 1-1 semi pressed state is then pressed As a result, the practitioner can be visually recognized.

Therefore, when the practitioner who recognizes that the half-depressed key 1-1 is the key to be depressed next, depresses the key 1-1, the hammer arm 28 is rotated clockwise for the first time. Then, the hammer 37 at the tip of the hammer arm 28 strikes the string 39. As a result, the string 39 is struck, and a musical tone with a pitch corresponding to the natural frequency of the string 39 and a volume corresponding to the striking force of the hammer 37 is produced. After striking the string, the key 1-
1 is returned to its original position by the hammer arm 28 and the weight 38 incorporated in the arm 28.

While the musical tone is being produced in this manner, the CPU 6 carries out various other processes such as whether or not the preselected tone color has been changed (step 4).
4) After that, it is determined by the tone length data LD read from the ROM 8 simultaneously with the tone pitch data KN whether or not the sounding time after driving the key 1-1 has reached the time indicated by the tone length data LD. (Step 45) If not reached, steps 44 and 45 are repeated until reached. However, if the pronunciation time has reached the time indicated by the tone length data LD, the pitch data KN,
The read address to the ROM 8 is updated to read the sound length data LD and the suction force data PD from the ROM 8 (step 46). After that, the CPU 6 determines whether or not the last musical tone of the music has been sounded (step 47), and if the musical tone generation ends, the musical tone generating operation in the automatic performance mode ends. However, if there are still musical tones that have not been pronounced, the process returns from step 47 to step 40.

As described above, even in a musical instrument that actually sounds a musical tone by striking a sounding body such as a string, the practitioner is instructed by making the key to be depressed next half depressed. Visually knows which key should be pressed next, and the pitch of the pressed key depends on the pitch of the musical sound that is produced when the user actually presses his / her finger 22. You can see if there is. Therefore, the key depression position and the musical scale can be learned not only by the visual sense but also by the tactile sense and the auditory sense, so that the practice effect of the music is dramatically improved.

Instead of striking the strings with the hammer 37, the pressure sensor may be pressed and a musical sound may be electronically generated by the output of the pressure sensor.

On the other hand, in the above-mentioned embodiment, the pitch data and the like of the music in the automatic performance and the navigation performance are stored in the ROM 8.
Although it is stored in advance in the above, the configuration may be such that it is transmitted from the outside in a time series in a wired or wireless manner.

Further, although the key to be pressed next is taught only once, if the same key is taught a plurality of times, the learning effect can be further enhanced for a beginner.

[0062]

The present invention according to the present invention generates a key driving data to be sequentially pressed accordance with the progression of the music piece, the order does not lead to the key to <br/> Therefore corresponds to the drive data to the normal depression depth by depressing the semi-depressed state of, teaches next key to be pressed, the key to this teaching state is further depressed, configured so that the pitch of the tone generation corresponding to said key is instructed Therefore, the key to be pressed next is visually confirmed by visually recognizing the key in the half-pressed state, then the key in the half-pressed state is pressed, and the pitch corresponding to the key is actually reached. by Rukoto instructs the tone generation, these steps that check both auditory tactile and ears by hand pitch corresponding to the key that has a half-depressed state, auditory tactile and ears by hand as well visual Depending on which key should be pressed next It becomes possible to practice playing operations while confirming through multiple senses what kind of pitch the position is in and the correspondence with the pitch, and as a result, it is possible to rapidly improve the playing operation of the desired music. Can be planned.
