Description

The present invention relates to a musical sound control device that controls musical sounds in accordance with body movements such as rhythmic gymnastics.

“Prior Art” Conventionally, musical tones have been generated by playing musical instruments such as a piano, a violin, and a bass drum, or by using a vocal cord. However, generating a musical sound according to the movement of the body (particularly the hand) in rhythmic gymnastics has not been performed conventionally.

"Problems to be Solved by the Invention" In view of the above circumstances, an object of the present invention is to provide a tone control device that generates a tone corresponding to a hand movement in rhythmic gymnastics or the like.

[Means for Solving Problems] In the first invention, the left and right hands are grasped, operation switches are attached to each of them, and a motion detecting means for detecting the movement of the stick is attached to at least one of them. 2 The first control signal for controlling the parameters of the musical tone is output in accordance with the states of the sticks of the book and the operation switches of the two sticks, respectively, and the generation of the musical tone is generated in accordance with the detection result of the operation detecting means. A control signal generating means for outputting a second control signal for instructing stop and a parameter of a musical tone generated corresponding to the combination of the first control signals are determined, and the second control signal is set to the second control signal. And a tone signal generating means for generating a tone based on the above.

According to a second aspect of the present invention, in the first aspect of the present invention, the two sticks are respectively attached with motion detecting means for detecting the movement of the sticks, and the control signal generating means is for detecting the motion detecting means of each of the sticks. A second control signal is output according to the result, and the musical tone signal generating means determines the parameters of all musical tones generated corresponding to each combination of the first control signals, and outputs the second control signal to each second control signal. It is characterized in that the musical tone of the parameter corresponding to each of the left and right is generated based on the above.

"Operation" The musical tone control device according to the present invention controls the generated musical tone corresponding to each output of the operation detecting means and the operation switch attached to the stick.

Thereby, for example, various musical tones can be freely generated by holding the stick in the hand, appropriately operating the operation switch of the stick, and moving the stick itself.

[Embodiment] A musical tone control apparatus according to an embodiment of the present invention will be described below. FIG. 1 is a view showing a rhythm stick S-1 used in this embodiment.
-1 is grasped by the operator's right hand, and is formed in a cylindrical shape, and the push button switch 1-1 is attached near the grip S-1a. An acceleration sensor 2-1 is attached inside the tip of the stick S-1. The acceleration sensor 2-1 is formed of a piezoelectric element such as a piezo plastic film. When the stick S-1 is shaken and acceleration in the direction of arrow R is applied, a signal of a level corresponding to the acceleration is generated. .
Although not shown, the stick S-2 having the same structure as the above-described stick S-1 is held by the operator's left hand. The outputs of the switch 1-1, the acceleration sensor 2-1 and the switch 1-2 of the stick S-2, and the acceleration sensor 2-2 described above are supplied to the control data generating circuit 3 of FIG. The control data generation circuit 3 includes the switches 1-1 and 1
-Check each operation state of -2, when each push button is pressed, "1" signal as signals SR and SL, and when released,
The "0" signal is output to the tone signal generation circuit 4, respectively. Also,
The control data generation circuit 3 compares the output signal level of the acceleration sensor 2-1 with a constant voltage, and when the signal level is higher than the constant voltage, outputs the signal "1" as the signal KR, and when the signal level is small, the signal KR. Outputs a "0" signal. Similarly, the output signal level of the acceleration sensor 2-2 is compared with a constant voltage, and the signal KL is output based on the comparison result. The tone signal generation circuit 4 creates a tone signal based on the above-mentioned signals SR, SL, KR, KL, and drives the speaker SP. That is, in FIG. 3, T1 to T7 represent the timbres of the generated musical tones, and the musical tone signal generation circuit 4 produces timbres T1, T3, when the signal KR is the "1" signal.
A tone signal having any one of the tone colors T5 and T7 is generated, and when the signal KL is the "1" signal, a tone signal having any one of the tone colors T2, T4, T6 and T7 is generated. Also the signal K
When both R and KL are "0" signals, no tone signal is generated,
When the signals KR and KL are both "1" signals, tone signals having both tone colors are generated. For example, when the signals SR and SL are "0" and "1" and the signals KR and KL are "1" and "0", a tone signal having a tone color T3 is generated and output to the speaker SP. Also, for example, the signal
When SR and SL are "1" and "0" and the signals KR and KL are "1" and "1", the tone color
A tone signal having T5 and T6 is generated and output to the speaker SP. Therefore, according to the above configuration, the operator holds the sticks S-1 and S-2 in the left and right hands, and the switches 1-
When 1, 1-2 are set with fingers as appropriate and the sticks S-1, S-2 are shaken at a certain speed or more, the musical tone of each tone color shown in FIG. 3 is generated from the speaker SP.

By the way, in the above embodiment, the push button switches 1-1,
When both 1-2 are on, the tone with the same tone T7 will be generated regardless of whether the left or right stick is shaken. In this case, by moving both hands, the tone with the same tone is generated at high speed. Because it is possible to
It is also possible to play 16th notes consecutively, such as the fill-in of playing technique, for example, repeated taps of a tom.

In the above embodiment, the acceleration sensors 2-1 and 2-2 are used to detect the movements of the sticks S-1 and S-2, but the present invention is not limited to this, and other sensors are used to detect the sticks S-1 and S-2. The movement of S-2 may be detected.

Further, although the tone color of the musical tone is controlled according to the states of the switches 1-1 and 1-2 and the acceleration sensors 2-1 and 2-1 in the above-described embodiment, instead of this, the volume of the musical tone, The pitch and the like may be controlled.

[Advantages of the Invention] As described above, by using the musical tone control device according to the present invention, various musical tones can be freely generated according to the movement of the stick and the operation state of the switch attached to the stick. Further, for example, by holding a stick in each of the left and right hands and moving either of the sticks so that a musical tone having the same tone color is generated, it is possible to generate a musical tone having the same tone speed by moving both hands. Since it becomes possible, it is also possible to repeatedly strike 16th notes such as fill-in of performance technique, for example, repeated taps of toms, and the expressiveness is improved.
