[Embodiment] Hereinafter, a musical tone control apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a noise generator used in the musical tone control apparatus according to the embodiment. In the figure, reference numeral 1 is a noise generator, which is composed of a box made of synthetic resin or the like and has a size that can be grasped by one hand. A large number of grooves are formed in a mesh shape on the inner wall surfaces of the side plates 1a, 1b facing each other of the noise generator 1, and innumerable small projections are formed on the inner wall surfaces of the side plates 1c, 1d facing each other. Further, wavy projections are formed on the inner wall surfaces of the side plates 1e, 1f facing each other. In addition, a hole is provided in the center of the side plate 1b, and the microphone 2 is inserted and fixed in the hole. A small amount of sand is put in the noise generator 1. When the noise generator 1 configured as above is shaken while being held in the hand, sand rubs against the inner wall surface of the side plate to generate noise. In this case, the sound generated from the noise generator 1 becomes a different sound due to the difference in the shape of the wall surface rubbing against the sand, the strength of the rubbing against each other, etc. Therefore, the output signal of the microphone 2 also becomes different. Waveform diagram of the output signal of the microphone 2 shown in FIG. 2 (horizontal axis: time,
In the vertical axis: amplitude), the part (a) is the noise generator 1
It is a waveform of the signal when the inner wall surfaces of the side plates 1a, 1b are rubbed against the sand, and the portion (b) is the waveform of the signal when the inner wall surfaces of the side plates 1c and 1d are rubbed against the sand, The portion (c) is the waveform of the signal when the inner wall surfaces of the side plates 1e and 1f are rubbed against the sand. The output signal of the microphone 2 is output to the circuit shown in FIG. In the figure, reference numerals 3, 4 and 5 are band-pass filters having different characteristics, which extract only the signal component in the preset frequency range from the output signal of the microphone 2 and supply them to the diodes 6, 7 and 8, respectively. Output. In this case, the bandpass filter 3 passes the frequency component peculiar to the noise generated by the sand and the inner wall surfaces (mesh) of the side plates 1a, 1b of the noise generator 1 rubbing against each other, and the bandpass filter 4 is also the same. , Pass the frequency components specific to the inner wall surfaces (innumerable small protrusions) of the side plates 1c, 1d,
Similarly, the bandpass filter 5 allows the frequency components specific to the inner wall surfaces (wavy) of the side plates 1e and 1f to pass therethrough.
The diodes 6, 7 and 8 rectify the signals output from the band pass filters 3, 4 and 5, respectively, and output the rectified outputs to the smoothing circuits 9, 10 and 11, respectively. The smoothing circuit 9 is composed of a resistor 12 and a capacitor 13, and the smoothing circuit 10 is a resistor.
14 and capacitor 15, and smoothing circuit 11
Is composed of a resistor 16 and a capacitor 17. These smoothing circuits 9, 10 and 11 smooth each rectified output and output it to the musical tone signal forming circuit 18 as musical tone control data. The tone signal forming circuit 18 inputs the output voltages of the smoothing circuits 9, 10 and 11 and sequentially checks the level, forms tone signals of tone color and volume based on the check result, and outputs the signals to the speaker 19
Output to. For example, when the output voltage of the smoothing circuit 9 is equal to or higher than a predetermined value, a tone signal of the tone color of the bass drum is formed,
The level of the formed musical tone signal is controlled by the level of the output voltage and output to the speaker 19. Similarly, when the output voltage of the smoothing circuit 10 is equal to or higher than a predetermined value, a musical tone signal of a drum tone is output to the speaker 19, and when the output voltage of the smoothing circuit 11 is equal to or higher than a predetermined value, the tone color of the cymbal is changed. The tone signal is output to the speaker 19. Further, when two to three of the output voltages of the smoothing circuits 9, 10 and 11 have a predetermined value or more at the same time, the tone signal of each tone color is mixed and output to the speaker 19.
