Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic musical instrument that allows the user to enjoy a ball hitting game and is suitable for teaching children's sense of pitch.

Generally, when teaching children's sense of pitch, it is preferable to add game-like elements so that they can develop their sense of pitch naturally while having fun.

However, conventional electronic musical instruments lack game-like elements and are not suitable for teaching children's sense of pitch.

An object of the present invention is to provide a new electronic musical instrument that incorporates elements of a ball hitting game that can enhance the educational effects of musical acuity.

The electronic musical instrument according to the present invention generates a musical tone that changes like a glistening sand to simulate the movement of a ball, and also makes it possible to enjoy a ball hitting game by making key presses on the keyboard correspond to the movements of a ball hitting tool such as a racket. The present invention will be described in detail below with reference to the accompanying drawings.

The figure shows an electronic musical instrument according to the present invention, and this electronic musical instrument is adapted to play a game similar to tennis, for example.

The keyboard 10 has a total of 24 keys, _K1 to _K24 ,
Key press data KD indicating the pressed key is supplied to the key range selection circuit 12.

If the game select switch SW is off,
Since the game play signal GPL is "0", the key range selection circuit 12 supplies key press data corresponding to the entire key range from the keyboard 10 to the gate circuit 14. Here, the gate circuit 14 uses the game play signal GPL=
Since the signal = "1" obtained by inverting "0" by the inverter 16 is received as the enable signal EN, the key depression data KD from the key range selection circuit 12 is supplied to the tone signal forming circuit 18. Therefore, the musical tone signal forming circuit 18 forms a musical tone signal corresponding to the key pressed on the keyboard 10 and supplies it to the speaker 20. Therefore,
In this case, a musical tone corresponding to the key pressed on the keyboard 10 is produced from the speaker 20, and normal manual performance becomes possible.

On the other hand, when the game select switch SW is turned on, the game play signal GPL becomes "1". Therefore, the gate circuit 14 becomes non-conductive, and the keyboard 1
Normal manual playing on keyboard 10 will no longer be possible, but you will be able to enjoy games similar to tennis on keyboard 10. That is, when the key range selection circuit 12 receives the game play signal GPL=“1” as the enable signal EN, the key range selection circuit 12 selects the first one on the bass side of the keyboard 10.
It becomes possible to select either the key range KR ₁ or the second key range KR ₂ on the treble side, and to send key press data KD from the selected key range. In this case, the keyboard 10 is divided into two parts at the center position N corresponding to the net, and the first keyboard area KR ₁ , which includes 12 keys to the left of N (low-pitched side), corresponds to one coated surface, and to the right of N (treble-pitched) The second key range KR ₂ containing 12 keys on the side) corresponds to the other court surface.

Since the game play signal GPL is also supplied to the pitch data generation circuit 22 as an enable signal EN, this circuit 22 can generate data from the first key range KR ₁ to the second key range.
It becomes possible to generate pitch data PD that sequentially changes in the direction of KR ₂ or in the opposite direction. The pitch data generation circuit 22 is composed of, for example, an up/down counter, and receives pitch data from it.
The PD is converted into a corresponding musical tone signal by the musical tone signal forming circuit 18 and then outputted by the speaker 20.

For example, the selection operation of the key range selection circuit 12 and the data generation operation of the pitch data generation circuit 22 are performed using R-
It is controlled by a control signal CN from a control circuit 24 consisting of an ST flip-flop. Each control circuit 24 has a set input S.
A key press signal from the lowest pitched key _K1 and a key press signal from the highest pitched key _K24 are supplied as a reset input R, and a serve is activated by pressing one of these keys _K1 and _K24 . It is becoming possible to do it. Note that a push button switch for serve may be provided separately from the keys _K1 and _K24 .

For example, if key _K1 is pressed and a serve is performed from the first key range _KR1 corresponding to the left court surface, the control signal CN becomes "1" and the key range selection circuit 12 is activated from the right court surface. 2nd key range corresponding to KR ₂
Select the key press data from this selected key range KR ₂ .
KD is supplied to the comparator circuit 26. Further, the pitch data generation circuit 22 generates the first pitch data in response to the control signal = “1”.
Pitch data PD that sequentially changes like a glissando from the key range KR ₁ to the second key range KR ₂ is generated and supplied to the comparison circuit 26.

The comparison circuit 26 compares the key press data KD and the pitch data PD at this time, and when the two substantially match, generates a match output NEQ. Here, the range that is determined to be approximately matched can be set as appropriate, but in this example, the range of two keys approximately matches the direction in which the pitch data PD changes from the pitch indicated by the pitch data PD. The range of

Now, suppose that when the pitch data indicates the pitch corresponding to the key marked * on keyboard 10, you press the white key to the right of it in response to swinging the racket.
Comparison circuit 26 generates a match output NEQ. This coincidence output NEQ is supplied to the control circuit 24 as a trigger input T, so the control signal CN becomes "0". Therefore, the selected key range in the key range selection circuit 12 and the pitch data change direction in the pitch data generation circuit 22 are reversed. That is, the key range selection circuit 1
2 supplies key depression data from the first key range KR ₁ corresponding to the left court surface to the comparison circuit 26, and the pitch data generation circuit 22
Pitch data that sequentially changes like a glissando from KR ₂ to the first key range KR ₁ is supplied to the comparison circuit 26.

Then, when an appropriate key is pressed in the first key range KR ₁ , a matching output is generated from the comparison circuit 26 in the same manner as described above.
Since NEQ is generated, the control signal is
CN becomes "1" and the selected key range and pitch data change direction are reversed again. Then, by repeating the same actions, a game similar to a tennis rally can be enjoyed.

Note that if the comparison circuit 26 does not detect a near match (corresponding to a miss), a carry or borrow signal is generated from the counter that constitutes the pitch data generation circuit 22, and the score is determined according to this signal. It is recommended that the information be displayed. Then, when a point is obtained, the player performs the next serve and can enjoy a rally game based on key presses in the same way as described above.

As described above, in this invention, the operation of hitting the pitch of a moving sound by pressing a key on a keyboard corresponds to the action of hitting a ball with a racket, and it is possible to enjoy a game similar to hitting a ball. Along with this, the effect of teaching pitch acuity by distinguishing between moving sounds is doubled. Furthermore, the structure is such that the moving direction of the moving sound is reversed each time the pitch of the moving sound and the pitch of the pressed key almost match, so you can enjoy a competitive ball hitting game where the ball goes back and forth. This will greatly increase the effectiveness of pitch training.
