Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic musical instrument that allows users to enjoy a guessing game by pressing keys and is suitable for music education for beginners and the like.

Generally, in music education for beginners, etc., it is preferable to add game-like elements so that the students can naturally become familiar with music while having fun.

However, conventional electronic musical instruments lack game elements.
It was not sufficient for music education for beginners.

An object of the present invention is to provide a novel electronic musical instrument that incorporates game-like elements in order to enhance the effectiveness of music education.

The electronic musical instrument according to the present invention is characterized in that a note name is displayed and a player can enjoy a note guessing game by performing a key press operation to press the key corresponding to the displayed note name. Hereinafter, embodiments shown in the accompanying drawings will be described in detail.

The figure shows an electronic musical instrument according to an embodiment of the present invention.

(2) The keyboard circuit 10 supplies the gate circuit 12 with a pressed key take KD indicating which key is pressed among the many keys on the keyboard.

When the game select switch SW is off, the game play signal GPL is %QI, so the gate circuit 12 conducts this signal GPL-IQ# in accordance with the signal inverted by the inverter 14, and outputs the signal from the keyboard circuit 10. Key press data K
D is supplied to the musical tone signal forming circuit 16.

The musical tone signal forming circuit 16 forms a musical tone signal corresponding to the pressed key in response to the key press input from the gate circuit 12,
The signal is supplied to the speaker 18. Therefore, a musical tone corresponding to the pressed key is produced from the speaker 18, and normal manual performance is possible on the keyboard.

On the other hand, when the game select switch SW is turned on, the game play signal GPL becomes turtle 11. As a result, the gate circuit 12 becomes non-conductive, making it impossible to perform normal manual playing on the keyboard, but it is possible to enjoy a game of guessing the notes by pressing the keys on the keyboard.

That is, when switch sw'1 is turned on, signal GPL:
111, the timing circuit applies a reset pulse Re.
, load pulses L11L3 and L3 are generated sequentially in the order described, and the enable signal IN becomes 11# immediately after the load pulse L3 is generated.

The reset pulse Re is an OR game) 22X24.
26 to the reset inputs R of the register circuits 32 and set on these circuits e IJ. After this reset, the register circuit array, (9)
, 32 are sequentially supplied with load pulses L, , L, , L3 to the load command input ends of the registers 32 and 32, respectively. The runtime pitch data RD from 34 is sequentially taken in and held.

Here, since the pitch data held in the register circuits 28, 30, and 32 are generated at different timings for the load pulses L1, L, , L, for example, rcjJ, "D", respectively.
”, “Asu”, etc. indicate different pitches.

Pitch data PD1 from register circuit, (9), 32
, FD, , FD are the corresponding display control circuits 36, 38 .
40, so these circuits 36.3B, 40
are the corresponding display sections 42a, 42b, 4 of the pitch name display 42.
2c to visually display the note names rOJ, rDJ, and rA town, respectively. The pitch name display 42 is composed of, for example, a liquid crystal display,
It is placed on the panel surface near the keyboard.

When a note name is displayed, such as the upper B pitch, key press operations are performed on the keyboard to press the key corresponding to the displayed note name.
At this time, the key press data KD is supplied to the priority circuit 44.

The priority circuit 44 is provided to preferentially send key press data corresponding to one of the keys when multiple keys are pressed on the keyboard. It is possible to determine in advance a key that corresponds to the key pressed first, a key that corresponds to a higher-pitched key, a key that corresponds to a lower-pitched key, etc.

The key press data corresponding to one key from the priority circuit I is supplied to the tone signal forming path 16 via the gate circuit 45 which is rendered conductive by the game play signal GPL=%l''.

Therefore, each time a key is pressed on the keyboard, the speaker 18 produces a single tone corresponding to the priority key press data. Further, the priority key press take from the priority circuit 44 is supplied to a comparison circuit 46 and compared with the output data from the selector circuit 48. The selector circuit 48 has an enable signal 11CN of 1.
1, a selection operation is performed in response to a 2-bit control signal ON periodically generated from a timing circuit.The selection operation is performed by a switching circuit (source) that receives the same control signal ON as a switching control input. ) is performed in correspondence with the switching operation.

In other words, selector circuit j1848 is register circuit A, (
Receive the pitch data PD1, FD2, and FD3 from AXB and C from AXB and C, respectively, and input A if the control signal ON is "01" and input B if ON is "10".
If ON is "11", each input cl is selectively transmitted. Further, between the switching circuits, the coincidence signal IQ from the comparison circuit 46 supplied via the AND gate 52 which is made conductive by the enable signal gn=%1 is connected to the control signal ON when the control signal ON is "01".
”, the signal is switched to the output terminal a, if ON is “10”, the signal is switched to the output terminal A, and if CN is “11”, the signal is switched to the output terminal C.

The control signal OR changes from "01" to "rii" during a certain period (for example, 4 seconds) in which the enable signal KNdf'l' level is maintained.
Since such changes are repeated periodically, with the change at t being one period C (several seconds), the comparison circuit 46 receives the key press data from the priority circuit 44, the input AXB of the selector circuit 48, The operation of first-order comparison with the pitch data corresponding to C is periodically changed.

Assuming that a key corresponding to the note name rOJ is pressed on the keyboard while the enable signal IN is at the 11'# level, the comparator circuit 46 synchronizes with the timing at which the selector circuit 48 selects the input A. A match signal IQ is generated. This match signal KQ is supplied between the switching circuits via an AND gate 52. At this time, since the input signal is supplied to the output terminal between the switching circuits, the AND gate 5
2] ICQ is the OR generator 2 from the output terminal a.
2 to the reset input R of the register circuit.

Therefore, the register circuit section is reset, all bits of the pitch data FD are set to %QI/, and accordingly, the display of the pitch name "0" on the display section 42a is erased.

Thereafter, when the keys corresponding to the note names rDJ and "Mu9" are pressed in sequence on the keyboard, the note name displays on the display sections 42b and p420 are sequentially erased in the same manner as described above.

Also, at this time, all bits of pitch data FD1 to FD, Fi are -Ol, and such data PDl,

The output signal of the inverter 56 which inputs N=%1N is also %
Since it is QI, output signal=s11 is generated. This NO
The output signal = Ant 1 from the R game) 54 is supplied to the scoring circuit section, and is also supplied to the bell sound generating circuit section.

Based on the output signal from the NOR gate 54, the scoring circuit calculates a score (for example, 5 points) corresponding to the disappearance of all pitch name displays on the display 42, and displays the score on the score display. Further, the bell sound generation circuit (a) generates a bell sound in response to the output signal from the NOR gate 54, and generates an end signal BD\1- at the end of the bell sound. This end signal B
! D is supplied to the timing circuit section, and in response to this, the timing circuit section resumes the same operation as described above in connection with the case where the 1st select switch f3W is pressed (7). Therefore, three new note names different from the previous one are displayed on the display 42, and the user can enjoy playing the second note guessing game on the keyboard while looking at this display.

The above operation is performed when all pitch name displays on the display 42 are erased during the 11 level period of the enable signal Fin. If it is not possible to erase all the note names, no points are obtained, the bell does not ring, and the following actions occur.

That is, when the %1 level period of the enable signal IN ends, the enable signal mN becomes wkOI' regardless of how many note names are left on the display 42, and the timing circuit section changes accordingly. The same operation as described above for the case where the game select switch SW is pressed resumes. Therefore, three new note names different from the previous one are displayed on the display 42, and the user can enjoy playing the second note guessing game on the keyboard while looking at this display.

As described above, according to the present invention, it is possible to enjoy playing a guessing game on the keyboard while looking at the displayed note names, thereby naturally developing a sense of pitch and becoming familiar with keyboard instruments and music. Therefore, the electronic musical instrument according to the present invention is extremely useful for music education for beginners.
