Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound effect generating method and a sound effect generating apparatus for generating a sound effect of a percussion instrument.

[0002]

[Prior Art and Problems to be Solved by the Invention]
The generation of percussion-based sound effects has been used in many performances and, in some cases, for the purpose of determining the overall rhythm. In generating the above acoustic effect, it is always necessary to have stretched planar covers of various sizes. This flat cover is usually struck with high-speed continuity by the drum drum or padded stick.

A set of drums containing a planar cover of this kind and made of natural materials, of course, consists of a number of drums standing next to each other. The set of drums described above has outstanding musical characteristics, often caused by the complete reverberation of the cover, often made of natural wild animal hides. ing.

On the other hand, however, an "electronic drum set" composed of a plurality of drum units, for example, 3 to 5 or 6 or more drum units, is generally known. More specifically, each of the plurality of drum units is provided with a pad made of a synthetic leather substitute. The pad is supported by the curved mounting portion and is struck by the drum drum.

The impact path of the drum drum in each drum unit is transmitted to a computer designed according to the environment of the computer itself via a trigger microphone that operates based on piezoelectric coupling. In this case, the computer may electronically convert the vibration delimited by two points into a special sound, or make the special sound audible through a headphone or a speaker by a suitable electronic amplification means. Is designed to be possible. Examples of this kind of special sound include a tone color corresponding to the above-described divided vibration (for example, a tone color of a cymbal, a drum, or another percussion instrument). Trigger microphones of the type described above are also commonly referred to as Pickups or trigger pickups.

The electronic drum set as described above has the following problems. In other words, the impact of the multiple pads that make up the drum unit is always too large when used at home, so practice playing for a long time using this type of electronic drum set. The fact that things are not allowed is a problem. These facts are even problematic when a particular student listens through a set of headphones to the actual sound effects that result from playing practice. The pads described above have a spatially stretched striking surface, as in the case of a drum made from nature. And these pads require a large space.

Furthermore, in a set of electronic drums such as the one described above, there is a more serious problem in the fact that the pads described above do not have the optimal elastic deflection characteristics. More specifically, this serious problem is that the desirable reverberant properties that can be produced by a naturally made drum are not even approximately achieved by a set of electronic drums with synthetic leather pads. Caused by facts. Due to these facts, when using a set of electronic drums in many ways, playing students and the general public can achieve a sound quality corresponding to the acoustic effect of a drum made from the natural world. Can not.

The present invention has been made in view of the above problems, and at least when the sound of a percussion instrument is not transmitted through a speaker, it can be actually used even when playing quietly in a relatively small space. A first object is to provide a sound effect generation method and a sound effect generation device capable of generating a sound effect based on a percussion instrument. Furthermore, the present invention guarantees high sound quality in percussion instruments and the acoustic effects generated by the sounds, and at the same time, produces acoustic effects that guarantee the elastic flexural characteristics similar to drums made from the natural world. It is a second object to provide a method and a sound effect generating device.

[0009]

In order to solve the above problems, in the method for producing a sound effect of a percussion instrument of the present invention (claim 1), a cable, a wire, a Bowden cable, etc. A straight stretch line having one of the shapes is clamped and taut at both ends and is held to allow vibration, which straight stretch line includes a drum tab and a pad. It is struck by either one of the striking rods to produce a pulse of vibration. Furthermore, the mechanical vibrations corresponding to the generated pulses of vibrations are received by a motion sensing part, for example a trigger microphone, and on the fastening part of the linear extension line or on this linear extension line. It is adjusted by and converted into vibration that is attenuated electrically. Such damped vibrations are transmitted to a downstream tonality computer that determines the actual acoustic characteristics according to its environment, and after being amplified, reproduced through either the headphones or the speaker.

On the other hand, in order to solve the above-mentioned problems, in the sound effect producing apparatus for a percussion instrument of the present invention (claim 2), it is operated by one of the drum drum and the padded striking rod. If the tightening load produces a percussion acoustic effect, the tightening load is a straight stretched wire having one of the following shapes: cable, wire, and Bowden cable, which eliminates the need for any planar configuration. including.

The sound effect generating method and the sound effect generating apparatus for a percussion instrument of the present invention employ a novel approach that has never been considered in order to generate a sound effect based on a percussion instrument. This approach completely removes the planar covering that was always used in the past,
Instead, it is carried out based on the fact that either the drum drumsticks or the padded striking rods are used to strike the linear extension lines. This kind of straight extension line usually consists preferably of a tightly clamped cable, a Bowden cable or other cable.

In the present invention, the fact that the use of a squeezed cable or a Bowden cable makes it possible to achieve optimum reverberation characteristics has been observed and demonstrated. More specifically,
In this case, it is preferred that the Bowden cable according to the invention be present because the essential components for carrying out the above-mentioned straight extension line tightening process are already present in the Bowden cable in a unique way. used.

Furthermore, by using a trigger microphone (the internal structure and overall configuration of which is already described, the trigger microphone itself is well known), it is generated by the sound effect generating method and apparatus of the present invention. It has also been observed and demonstrated that such dampening mechanical vibrations, i.e. pulses of vibrations due to the effects of shocks, are converted into electrical time characteristics.
This electrical time characteristic is provided by a computer specially designed and prepared for the purpose of such conversion.
Finally, it is converted into a desired tone color (tone of drum, cymbal, or other percussion instrument).

The advantages of the present invention that should not be underestimated are:
The first vibration stimulus, that is, the process of mechanical vibration,
In other words, it progresses in a substantially silent state, in other words,
It is almost inaudible. The reason for this advantage is that the Bowden
The fact is that the cable only needs to be tapped, and that it itself does not generate mechanical vibrations due to impact and being directly audible. In this case, in the present invention, silent mechanical vibration is generated instead of mechanical vibration that can be heard directly. Furthermore, after converting the mechanical vibration into an electrical time characteristic by the trigger microphone that detects this silent vibration, it becomes very clear when the actual sound processing process is performed by the special computer in the downstream. A perfect sound with excellent sound quality is generated. Of course, the Bowden cable can also be struck very powerfully.

Therefore, in accordance with the present invention, a set of meaningful electronic drums, and more specifically, in view of the foregoing, may be any desired number of drum units and cymbal units, eg, three to three. It becomes possible to easily configure a set of electronic drums which is composed of 5 or 6 or more drum units and cymbal units and has the following functions. That is,
A set of electronic drums can be constructed that can be easily transported, since it requires only a small space, and because there are no longer planar components with large dimensions.

Therefore, in the simplest case, the percussion sound effect producing device of the present invention typically comprises a mounting portion having a U-shaped configuration. This attachment is for fastening the cable or Bowden cable in place with the drum drum or padded striking rod of interest. In this case, the drum drum above,
Alternatively, a padded striking rod strikes the cable in a clamped state with appropriate continuity.

As a result of using the above-described sound effect generation device, a continuous sound that is convincing to a person can be heard through a set of headphones. Apart from that, this kind of sound
It is also possible to listen through a speaker. In this case, of course, it is possible by means of drum drums to strike the clamping device for the various available Bowden cables with high speed continuity. In this case, each of the plurality of Bowden cables described above is connected to various internal input and tonal channels of a computer, preamplifier, etc.

According to the present invention, the combination of the acoustic effect generating devices for generating the acoustic effect based on the percussion instrument comprises:
Even the most intense performances of a continuous use of this type of drum set can be noticeably quiet enough not to produce a sound that exceeds daily noise levels. On the other hand, each of the plurality of drum units having a plurality of linear stretch lines and used therein produces a flexural characteristic that closely resembles a drum made from nature. This flexural property is also suitable for use as a substitute for cymbals after appropriate acoustic processing by a computer.

Advantageous expansions and improvements of the invention are possible on the basis of the features as indicated in the subclaims 3, 4 and 5 of the appended claims.

According to the acoustic effect generating device of the third aspect, the two ends of the linear extension line are respectively received at the free tightening ends, and the two ends are supported in the elastically bending manner. A mounting portion is provided. This mounting portion, by the impact of the drum's flap and the padded striking rod against the linear extension line,
A mechanical vibration pulse can be newly generated, and the mechanical vibration pulse is converted into an electric vibration pulse by a trigger microphone and further transmitted to a tonality computer.

Furthermore, according to the sound effect producing device of the fourth aspect, the attachment part has an essentially U-shaped shape which is fixed so as to support a linear extension line having the shape of a Bowden cable. It consists of a supporting frame. This support frame
The straight extension lines are rigidly fixed in the vertical arms that can be reinforced by one intermediate member. In this case, the trigger microphone is fixed at the position of the Bowden cable on the mount, or at a point on the mount other than the Bowden cable.

Further, according to the acoustic effect generating apparatus of claim 5, the mounting portion has a plurality of curved end portions and is one steel member which is curved with the same radius, for example,
A piece of spring steel. A steel member of this kind is further stretched by a straight stretch line due to the inherent elasticity of the steel member itself.

The above-described sound effect producing device is particularly advantageous in the form of a general Bowden cable and in constructing a straight extension line which is treated by the drum drum. The linear extension line of such a shape has a plurality of corresponding fitting parts such as a shaft sleeve, a mesh cable (Cable-eyes), and a crimp connection (Crimp Connections).
Also, by using a threaded extension, it can be easily inserted or tightened into a suitable U-shaped mounting part that supports at both ends or any other mounting part. is there.

Thus, in the present invention, a substantially silent mechanical vibration is generated by utilizing the tightening load of a straight extension line such as a Bowden cable, and the mechanical vibration is converted into a vibration exhibiting an electrical time characteristic. Therefore, it is possible to generate a sound effect that can be actually used even when playing quietly in a relatively small space. Further, in the present invention, by appropriately adjusting the tightening load of the linear extension line, excellent sound quality in the acoustic effect generated by the sound of the percussion instrument is guaranteed.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram schematically showing a possible basic configuration of a percussion instrument sound effect generation apparatus according to the present invention, which comprises a downstream tonality computer.

In the embodiment of the percussion sound effect generator shown in FIG. 1, the basic idea of the invention is that the straight line preferably has the shape of a Bowden cable and does not require a planar shape. It is to design a tightening load such as a linear extension line. Further, in the above embodiment, the impact contact by either the drum drum and the padded striking rod causes mechanical vibration in the region where the Bowden cable is clamped and fixed. . The above area is the Bowden cable itself,
It refers to the mounting that supports this Bowden cable. Furthermore, the mechanical vibration generated in this way is
It is converted into electrical vibration by a trigger microphone, pressure sensor or vibration sensor. Thereafter, the converted electrical vibration is converted into a sound effect corresponding to drum performance, cymbal sound, or other percussion instrument sound by using the tonality computer 14.

As shown in FIG. 1, the percussion instrument acoustic device 8 is
The mounting portion 10 is made of a rigid holder or frame. However, this type of mounting 10 also has a slight elastic flexing characteristic. The mounting portion 10 is basically made of any material. Further, the mounting portion 10
Supports the linear extension line 12 at its free end in such a manner as to clamp the linear extension line 12.
This straight extension line 12 usually has the form of a cable or wire, more preferably a cable called the Bowden cable.

The mounting portion 10 is an arm portion 1 of the base portion.
0a and two arm portions 10 extending vertically from the side portion
It has a basically U-shaped configuration as constituted by b and 10c. Here, the side vertical arm portion 10b,
10c supports Bowden cables at their free ends (ends of cantilever) 11b, 11a, respectively. Furthermore, in order to reinforce these arms 10b, 10c to ensure a firm tightening of the Bowden cable, said arms 10b, 10c are supplemented by a cross member 10d near the tightening point of the Bowden cable. Connected to each other in various forms.

The mount 10, such as a frame with a cross member of this kind, is preferably made of a plurality of rods of robust rectangular brass. The plurality of rods are connected by bolts or by welding.

According to the mounting portion 10 as described above, the Bowden cable forming the straight extension line 12 is tightly tightened by the screw thread (male screw) 15 and is vertically attached to the arm portions 10b and 10c. It is firmly fixed. Further, the Bowden cable is fixed at one end thereof with a screw (female screw) 15a for properly tightening the Bowden cable.
By such a method of tightening the Bowden cable,
It is possible to use the drum drum 16 or a padded striking rod to generate mechanical vibrations essentially through the entire mount, such as the frame, and within the Bowden cable. This mechanical vibration is caused by the trigger microphone 1
3 is detected and converted into electric vibration pulses.

Referring to FIG. 1 in more detail in connection with the above facts, it is basically the trigger microphone 13
Can be installed at any point. For example, the trigger microphone 13 may be located at the portion of the screw 15a or at the portion 13 'on the vertical arm. The vibrations of the mechanical damping produced by the impact of the drum dovetail 16 reach all points in the frame-shaped mount 10 and the Bowden cable by virtue of the structurally provided conduction. These mechanical vibrations are then transmitted to a specially modified downstream computer after the sampling process has been performed. This type of computer will hereinafter be referred to as the tonality computer 14.

The tonality computer 14 operates according to the well-known procedure which has already been described with respect to the conventional sound effect generating apparatus including the drum set having the flat pads as described above. Then, the above-mentioned tonality computer 1
4 has the ability to generate any desired tonal character (tonal character from a drum, cymbal, or other percussion instrument) based on the pulses of vibration transmitted to the tonality computer 14. There is. Furthermore, if appropriate,
It also has the ability to transmit the tonality of the generated sound to the appropriate acoustic transducer 17 downstream of the tonality computer 14 either immediately or later, after amplification. There is. This type of acoustic transducer 17 is preferably composed of headphones or a speaker. Further, the mounting portion 10 also includes a piece of spring steel (rod) that is uniformly curved with a constant radius of curvature.

According to the configuration of the embodiment shown in FIG. 1 as described above, as a result, the sound effect of the percussion instrument is not substantially confused by a person but substantially different from the conventional method. Can be generated. Further, such a sound effect generation method can be perfectly used for general public performance and other performances.

Therefore, the sound effect producing apparatus of the present invention, in which an excellent result is guaranteed in an environment having almost complete tranquility, is suitable for playing at home. Further, it is possible to reconfigure the band or other percussion division of the orchestra in the same innovative way with the new type of percussion instrument according to the invention. And, if appropriate, other new effects can be achieved.

FIG. 2 shows a multiplicity of percussion acoustical devices according to the invention, such that, if desired, all the percussion acoustical devices are arranged on a single support in a space-saving manner. It is a figure which shows an aggregate. Note that, hereinafter, the same components as those described above will be denoted by the same reference numerals.

In the normal case, as shown in FIG.
A single percussion acoustic device 8 is used, such as with a straight stretch line 12 according to the invention. However, more preferably, a number of percussion instrumental acoustic devices, for example 7-8, are used. Specifically, FIG. 2 shows an example in which five percussion instrument acoustic devices 8a, 8b, 8c, 8d and 8e are installed together.

The above-described percussion instrument audio devices 8a-8e have Bowden cable lengths that are individually and completely distinguishable, as well as the dimensions of the mounts that are individually distinguishable (free. The length of vibration is about 15 cm). As a reason for adopting such a configuration, as described above, by performing special setting of the tonality computer 14 for each of a plurality of channels connected to the tonality computer 14, a desired tone color is first produced. Points to be achieved are listed.

More specifically, sound enhancement is not based on the vibration characteristics of the individual Bowden cables, but more strictly, it depends on the length of each Bowden cable. It is possible to achieve the desired timbre as described above because the sound is emphasized based on the pulse characteristics that result from the impact applied to the Bowden cable, rather than based on the resonance frequency generated by the become. The tonality of this kind of sound is completely guaranteed by the tonality computer 14.

With the above-described structure, the entire apparatus is smaller than the conventional one, and therefore it is possible to easily carry the individual percussion instrument audio devices 8a to 8e whose sizes are distinguishable from each other. Moreover, these percussion acoustic devices 8a-8e can also be fixed to appropriate points within the single support 18 (FIG. 2), respectively, without requiring a large occupied space. More specifically, the percussion acoustic device 8a
8e, by using screw fasteners or other intermediate support members respectively corresponding to 8e, musicians located at the front of a complete set of sound effect generators of the type described above require easy and great effort. Instead, these percussion instrument audio devices 8a-8e are fixed in such a way that they can reach for the percussion instrument audio devices 8a-8e.
The tonality computer operates a set of headphones 19 depending on whether a simple performance period is included,
Alternatively, the appropriate (stereo) speaker 20 is activated for the performance of music.

It will be readily understood that in the embodiment of FIG. 2, the attachment for the straight extension line, ie the support (single support 18), is absolutely essential. .
In other words, the shock that finally causes mechanical vibration (shock of drum or impact of padded striking rod)
Thus, the attachment is the only essential requirement for holding a straight extension line in order to generate the final electrical pulse through the conversion by the trigger microphone. In this case, as described above, the above electric pulse can be analyzed by an appropriate method.

In the description of the sound effect generator of the present invention,
The term "trigger microphone" also encompasses the conceivable alternative transducer device, which has the ability to transform detected pulses of mechanical vibrations into a series of electrical signals. In the present invention, a device having a piezoelectric microphone can be preferentially used as this type of conversion device. However, enumerating only a few transducers other than piezoelectric microphones,
Other devices based on capacitive, magnetostrictive, electromagnetic or inductive coupling are also conceivable. These devices can also be used in place of devices with piezoelectric microphones.

Furthermore, in the sound effect generating apparatus of the present invention,
For example, it is possible to guide the linear extension line towards both ends of the mounting part, while it is also possible to guide it towards only one end part. When fixing the linear extension line to only one end of the mounting part like the latter,
The linear extension line is fixed by being folded back (in a state of having tension) through the outer peripheral portion of the supporting roller of the mounting portion. In any case, the trigger microphone described above can be located anywhere on the straight extension line and its support (e.g. suspension).

Finally, in the present specification, with respect to a plurality of claims in the claims, particularly, a main claim (independent claim) as a basis, it is caught or limited by comprehensive knowledge of the prior art. It should be noted that attempts have been made to verbalize the sound effect generation method and apparatus of the present invention without imposing a prejudice. The right to be read from the above claims shall be construed to relate to all features as disclosed in the claims, the detailed description of the invention and the drawings. In this case, in order to avoid unnecessarily narrowing the scope of rights of the main claim, the constituent features in the main claim and the description about the features of the present invention are kept to the minimum necessary, and the main claim So I try to mention only absolutely essential matters. However, since the features and components of the present invention are all included in the auxiliary claims (dependent claims) other than the main claim, the features of the present invention can be achieved by combining individual claims and some claims. It is considered that the entire contents are covered.

In the percussion instrument sound effect generation method and device of the present invention, various possible modifications and alterations are conceivable in addition to the above-described embodiments. However, the description of these variations and modifications will not provide any particular novelty for understanding the present invention.
