Abstract

PURPOSE: To reproduce three kinds of timbre in the same playing style with an original musical instrument by providing three pads which generate sounds when hit with sticks and reproducing the different sounds when the respective pads are hit. CONSTITUTION: The three pads 1-3 are arranged in ergonomics view so as to reproduce the same timbres with the original musical instrument. To reproduce a Latin sound, a 1st pad 1 in the same shape with a spherical projection provided at the center part of the original musical instrument is arranged inward, a 2nd pad 2 in a flat shape for generating a ride sound is arranged in front of the 1st pad, and a 3rd pad for generating a crush sound is arranged before the 2nd pad 2. Thus, the pads 1-3 are arranged to reproduce the three kinds of sound that can not be reproduced by a conventional electronic percussion instrument by exactly the same playing technique with the original musical instrument. For reproduced timbres, the sound of the original musical instrument is recorded and processed into signals, which are stored in a sound source output means, so that the sound is generated once the pads 1-3 are hit with the sticks.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an electronic percussion instrument that can generate an electronic sound source by causing conductive rubber to conduct a circuit on a printed circuit board by hitting a rhythm pad with a stick. It is something.

(Prior Art) Generally, an electronic percussion instrument consists of two parts: a rhythm pad section which is an input means, and a sound source output means which makes a sound source sound using a signal sent from the input means. As shown in FIG. 9, a thin resin plate 42 with a rubber pad 41 adhered to the upper surface, a conductive rubber layer 4 on silicone rubber 43,
4 and a plurality of insulating protrusion layers 45 integrally molded, and a printed circuit board 48 in which ten-polar foils 46 and unipolar foils 47 are alternately arranged at very short intervals within an area equal to the outer shape of the rubber pad 41, in order from the top. They are stacked one on top of the other and fixed between the cabinet 49 and the bottom plate 50 with screws 51.

Next, the operation will be explained. Rubber pad 4 with stick 52
1, the conductive rubber layer 44 deforms and the insulating protrusion layer 45
While crushing the foil, it is brought into close contact with the foil surface of the printed circuit board 48, and is brought into contact with the ten-polar foil 46 and the one-polar foil 47 at the same time, thereby making the circuit conductive. The conductive signal obtained by this input means 53 is sent to an externally provided sound source output means 54, and a designated sound is generated from a speaker 55.

(Problem to be Solved by the Invention) However, such electronic percussion instruments have the drawback that they can only reproduce one type of tone, the type that occurs when the cymbal of the original instrument is struck. Ta. This drawback will be explained with reference to FIG. In the same figure, the cymbal 56 is a disc-shaped brass plate that is pressed and squeezed, and when played, a lower cushioning material 58 is attached to a stand 57.
, put the cymbal 56 on it, and put the upper cushioning material 59 on it.
It has a structure in which it is fixed to a bolt shaft 61 of the stand 57 with a nut 60 via. Cymbals with this structure can produce the following three types of tones.

(A) The tone produced when the spherical projection provided at the center of the cymbal is struck. This tone is hereinafter referred to as the Latin tone.

(B) The tone produced when the flat part formed on the outer periphery of the cymbal is struck from the center. This tone is hereinafter referred to as the ride tone.

(C) The tone generated when the outer edge of the cymbal is struck. This tone is hereinafter referred to as a crash sound.

In this way, electronic percussion instruments have the disadvantage that they can hardly be used in actual performances because they can reproduce only one type of tone that can be produced by the original musical instrument.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic percussion instrument that eliminates the drawbacks of the prior art and can reproduce three types of tones produced by the original instrument using the same playing method as the original instrument.

(Means for Solving the Problems) The electronic percussion instrument of the present invention consists of three pads that generate sound when struck with a stick, and when the first pad is struck, a spherical protrusion provided at the center of the original instrument When you hit the second pad, the sound of hitting the flat part of the outer periphery from the center of the original instrument is reproduced, and when you hit the third pad, the sound of hitting the outer edge of the original instrument is reproduced. It is configured so that the sound is reproduced, and the first pad and the second
It is configured so that when two pads are struck at the same time, only the sound of the second pad is produced, and furthermore, when the second and third pads are struck simultaneously, only the sound of the second pad is produced. It is configured so that this occurs.

(Function) The electronic percussion instrument of the present invention has three pads ergonomically arranged to reproduce the same tone as the original instrument using the same playing technique as when playing the original instrument. In other words, when producing a Latin sound, a first pad with the same shape as the spherical protrusion provided at the center of the original instrument is placed at the back, and a flat second pad that produces a light sound is placed in front of the first pad. A third pad that produces a crash sound is placed in front of the second pad. This is a reproduction of the shape of the front part of the original instrument, and is sufficient for practical performance. By arranging the pads in this manner, sounds that could not be reproduced with conventional electronic percussion instruments can be reproduced using exactly the same performance technique as the original instrument. As for the tone to be reproduced, the sound recorded from the original musical instrument is signal-processed and stored in the sound source output means, and the sound is generated at the same time as the pad is hit.

(Example) An example of the present invention will be described based on FIGS. 1 to 5.

FIG. 1 is an exploded diffusion diagram showing the component structure of the electronic percussion instrument of the present invention, and FIG. 2 is a sectional view taken along line DD in FIG. In the figure, a thin resin plate 4 with a first pad 1, a second pad 2, and a third pad 3 bonded to the upper surface is attached to a cabinet 5.
A rubber plate on which a silicone rubber layer 6, a conductive rubber layer 7, and an insulating protrusion layer 8 are integrally formed is placed below it. Below that are three switch circuits S in which ten-polar foils and unipolar foils are arranged alternately at short intervals. Insert the printer I/substrate 9 with l 811 S2 formed on the top surface. Switch circuit S. is independently provided under the first pad 1, the switch circuit S1 is provided under the second pad 2, the switch circuit S2 is provided under the third pad 3, and 10 is the switch circuit S. 11 is a switch circuit S. 12 is the 10-polar foil of the switch circuit S1, 13 is the switch circuit S1

is the unipolar foil of the switch circuit S. Next, the bottom plate 16 is placed under the printed circuit board 9 and fastened to the boss 18 of the cabinet 5 with screws 17, and the cabinet 5 is fastened to the bottom plate 16 from the side with screws 19. Reference numeral 20 designates onime nuts 1 to 1, which are fitted into the bottom plate 16 and can be fixed to the stand 21 with screws.

Next, the operation will be explained using FIG. 3, taking as an example the case where the second pad 2 is hit with the stick 22.

When the second pad 2 is hit with the stick 22, the conductive rubber layer 7 is deformed through the thin resin plate 4 and the silicone rubber layer 6, crushing the insulating protrusion layer 8 and destroying the switch circuit S on the top surface of the printed circuit board 9. It is brought into close contact with the ten polar foil 12 and the unipolar foil 13 at the same time to make the switch circuit S□ conductive.

The first pad 1 and the third pad 3 also operate in the same manner, but as shown in FIG.
- and the third pad 3 is configured to be hit with the body of the stick 22 (the same applies to the cymbal of the original musical instrument), so compared to hitting the second pad 2 with the tip of the stick 22, the conductive rubber layer 7 is difficult to deform. Therefore, the first pad 1 is divided into four parts from the center so that the force of the stick 22 is easily transmitted to the conductive rubber layer 7. The third pad 3 is also divided into several parts for the same reason.

Next, the electrical operation will be explained using FIGS. 4 and 5.

In step 37, the sound source of switch circuit S2 is output, and the process returns to step 31 again.

As described above, according to this embodiment, by providing three pads that generate specific tones when hit with a stick, when the first pad is hit, the spherical shape at the center of the original instrument (cymbal) The tone produced when you hit the protrusion (Latin sound) is reproduced, and when you strike the second pad, the tone produced when you strike the flat part formed on the outer periphery from the center of the original instrument (light sound) is reproduced. ) is reproduced, and when the third pad is hit, the tone (crash sound) generated when the outer peripheral end face of the original instrument is hit is reproduced.

At this time, if you accidentally hit the first and second pads at the same time, or if you accidentally hit the second and third pads at the same time, only the sound of the second pad will be generated. However, it is configured to assist the playing technique by generating a ride sound that does not feel unnatural to the listener.

Therefore, unlike conventional electronic percussion instruments, it does not have the disadvantage of being able to reproduce only one of the three tones that can be produced by the original instrument, and the three tones that the original instrument can produce with the same playing technique as the original instrument. Since it can reproduce different tones, electronic percussion instruments, which until now could not be used in actual performances, can now be used on stage.

(Effects of the Invention) According to the present invention, the drawback of conventional electronic percussion instruments in that they cannot reproduce only one of the three types of tones produced by the original instrument is eliminated, and the same Using performance techniques, it is possible to reproduce the three types of tones that the original instrument can produce, and electronic percussion instruments, which until now could not be used in actual performances, can now be used on stage, and the practical effects are extremely large.
