Abstract

PURPOSE:To reflect player's intent as well as an acoustic instrument by inputting pressure to a detection part while playing music by the electric instrument. CONSTITUTION:A diffusion type semiconductor pressure sensor 1 consists of a detection terminal 2 and an amplifier 3 and outputs an electric signal corresponding to variation in expiration pressure. This semiconductor pressure sensor 1 is held in a mouth and the expiration pressure applied to the sensor 1 is controlled simultaneously with the playing of the electric instrument. An electric signal is outputted correspondingly to the pressure to control the sound volume, timbre, frequency, sound sequence, connection time of sound, length of sustainment, strength of attack, rhythm pattern, etc., of a musical sound sound outputted by the electronic instrument which is connected thereto. Consequently, variation of performance is widened and player's intent is reflected more than an acoustic instrument.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic musical instrument in which a diffusion type semiconductor pressure sensor is attached to a musical instrument signal generated by a sound source circuit to control various elements of sound.

(Prior art) 0N10 is used to control the sound emitted from electronic musical instruments.
Examples using the FF function or detecting the position are known. However, there is no known device or method for actively controlling the elements of musical tones through the actions of the performer.

(Technical Issues) For example, on an electronic piano, the things that a performer can control to form musical sounds are the keyboard and pedals, followed by the buttons for chords, rhythm, etc. However, if you can control specific individual elements such as the volume, timbre, frequency, sequence of notes, duration of notes, length of the sting, and strength of the attack, you can significantly improve the performance of the instrument. can be increased.

The purpose of the present invention is to create a semiconductor pressure sensor (= J-Raiko musical instrument) that can reflect the performer's intention in the same way as an acoustic musical instrument by covering the above-mentioned sound elements in a controllable manner. Part 4 - It's in the middle of the day.

(Technical Means) The object is characterized in that a semiconductor pressure sensor for detecting pressure horns such as gas pressure, mechanical pressure, tension, compression force, etc. is electrically connected to an electronic musical instrument. This is achieved by an electronic musical instrument equipped with a semiconductor pressure sensor.

The reason why a semiconductor pressure sensor was used as the control means was because of the fact that among various means and methods, pressure change is the physical quantity that is most easily sensed (detected) directly. Furthermore, semiconductor pressure sensors have high accuracy and stable operation, making them highly reliable.

Most electronic musical instruments are played using the hands and fingers, but other hands, feet, or mouth can be used to operate the pressure force, especially the mouth where exhalation pressure or chewing pressure can be used. is suitable, and the pressure detection method can be changed accordingly.

(Operation of the Invention) The electronic musical instrument is activated, and at the same time as the electronic musical instrument is operated and played, an input operation is performed on the pressure detection section to control the elements of the performance sound. is carried out as in the case of the embodiment.

That is, the semiconductor pressure caser is held in the mouth, and the exhaled air + and 1 applied to the sensor are controlled at the same time as the electronic musical instrument is played. Then, an electrical signal is output according to that pressure, so by connecting this, you can control the volume, timbre, number of groups, note sequence, duration of notes, sustain length, and attack strength of the musical sound signal output from the 7j electronic musical instrument. This means that you can control rhythm patterns, etc.

(Embodiment) The following is an explanation of the embodiment. Fig. 1 shows a diffusion type semiconductor pressure sensor 1, which consists of a detection end 2, an amplifier 3, etc., and is applied to the detection end. It outputs an electrical signal according to the pressure change of exhaled air.

The musical instrument main body 4 shown in FIG.
(Voltage Controlled Ampl
9, and is controlled by CΔ9 by the control signal from the semiconductor pressure sensor 1, and is emitted as an audible sound with a spill force of 10 J: as the sound of the electronic musical instrument of the present invention. , 11.12 indicate amplifiers.

The electronic musical instrument is an I'J Lake M I I) I musical instrument, MI [) that has a sound source module equipped with the above-mentioned short MIDI terminal.
■It is also possible to configure the device 13, in which case the output of the pressure sensor 1 is digitally converted by the A/D converter 14, and then sent to the CPU 15, where it is converted into MIDI data and sent to the upper sound source module. It will be done.

The diffusion-type semiconductor pressure sensor shown in FIG. 1 is used, and in addition to the exhaled air, mechanical pressure, tension, compressive force, etc. are used as inputs to the sensor. For example, an electronic drum can input changes in membrane tension, an electronic accordion can input changes in air pressure due to a bellows, and a pedal can input changes in internal pressure due to screws connected to it.

(Effects of the Invention) Since the present invention is configured as described above, it is possible to control the musical sound output by playing the musical instrument by manipulating the pressure at the same time as the playing of the musical instrument itself, thereby controlling the tone and color. It is possible to incorporate changes in frequency, tone sequence, rhythm pattern, rl duration, listen length, attack strength, etc., expanding the range of performance and making it comparable to or even better than an acoustic deck instrument. It has a remarkable effect of reflecting the intention of the performance sound.
