DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a cymbal,
More specifically, the present invention relates to a cymbal suitable for use as a practice cymbal or an electronic cymbal.

[0002]

2. Description of the Related Art In general, a cymbal as an acoustic musical instrument is generally made of a hard metal material such as phosphor bronze and is thin (for example, about 1 mm) in a substantially disk shape, that is, a substantially circular flat plate shape. It is formed as a body.

[0003] Such a cymbal is unsuitable for practicing in a small room or the like, since the sound (hitting sound) generated when hit with a hitting body such as a stick is extremely loud.

[0004] For this reason, in recent years, practice cymbals have been proposed in which the volume of a hitting sound generated by hitting a hitting body such as a stick is suppressed.

[0005] Further, while suppressing the sound volume of a striking sound generated by striking a striking body such as a stick, the striking force by striking the striking body such as a stick is detected.
An electronic cymbal that controls generation of a musical tone based on the hitting force has also been proposed.

The above-mentioned conventional practice cymbals and electronic cymbals are made of synthetic resin such as plastic instead of hard metal material such as phosphor bronze in order to reduce the sound of a blow when struck by a striker such as a stick. When formed using a material or a hard metal material such as phosphor bronze, a buffer plate such as rubber is attached to a hitting portion on the surface of the hard metal material such as phosphor bronze, and the buffer is formed. The ball was hit with a hitting body such as a stick on the board.

However, a cymbal as an acoustic musical instrument is formed of a hard metal material such as phosphor bronze itself, and hits the surface of a hard metal material such as phosphor bronze with a striker such as a stick.
Compared to the above-mentioned plastic cymbals and electronic cymbals for plastic practice, or practice cymbals and electronic cymbals in which a shock-absorbing plate such as rubber is attached to the impact site on the surface of a hard metal material such as phosphor bronze, a hit body such as a stick Therefore, the hit feeling such as the rebound of the hit body and the swinging state of the entire cymbal at the time of hitting is greatly different, and there is a problem that the player feels strange.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the object of the invention when hitting with a hitting body such as a stick. While suppressing the generation of impact sound,
An attempt is made to provide a cymbal that is suitable for use as a practice cymbal and an electronic cymbal that reduce a sense of incongruity given to a player by reducing the feeling of impact when struck by a strike body such as a stick or the like as a cymbal as an acoustic instrument. Things.

[0009]

In order to achieve the above-mentioned object, a cymbal according to the present invention uses a metal material so that a hit feeling when hit with a hitting body such as a stick is close to that of a cymbal as an acoustic musical instrument. The impact sound generated when striking with a striker such as a stick by forming the entire cymbal and reducing the vibration area by making many small holes throughout the cymbal, and promoting vibration damping by dispersing the vibration Is made smaller. For this reason, while the generation of a hitting sound when hitting with a hitting body such as a stick is suppressed, the feeling of hitting when hitting with a hitting body such as a stick becomes close to a cymbal as an acoustic instrument, and is given to the player. Discomfort is reduced.

That is, according to the first aspect of the present invention, the whole plate is formed of a metal material as a thin plate-like plate having a small thickness. A large number of small-diameter through holes extending in the direction are formed.

Therefore, according to the first aspect of the present invention, when the cymbal is hit with a hitting body such as a stick, the entire cymbal is formed of a metal material. The impact feeling such as the bounce of the impacting body when hit by the body and the shaking state of the entire cymbal is very close to the cymbal as an acoustic instrument, but since the cymbal has many small diameter through holes, When the cymbal is hit by a striking body such as a stick, the vibration area of the entire cymbal is reduced, and the vibration wave transmitted to the front or back surface of the cymbal is cut off by the through hole to disperse the vibration. As a result, the damping of the vibration due to the hit is accelerated, and as a result, the hitting sound when hitting the cymbal is an acoustic sound. Compared to cymbal as click instrument becomes significantly small.

According to a second aspect of the present invention, in the first aspect of the present invention, a cushioning member is provided at an outer peripheral edge of the plate-like body. It is.

Therefore, according to the second aspect of the present invention, since the cushioning member is provided on the outer peripheral portion of the cymbal, the vibration when the cymbal is hit is also absorbed by the cushioning member. Therefore, the impact sound when the cymbal is impacted can be further reduced.

Further, the invention described in claim 3 of the present invention relates to any one of claim 1 and claim 2 of the present invention.
In the invention described in the paragraph, a sheet is disposed on at least a surface of the plate-like body that is hit by the hitting body.

Therefore, according to the third aspect of the present invention, the vibration when the cymbal is hit is also absorbed by the sheet, so that the hitting sound when the cymbal is hit can be further reduced. it can.

[0016] The invention described in claim 4 of the present invention is the same as the invention described in claim 1 or 2 of the present invention.
In the invention described in the paragraph, a buffer surface is formed by coating on at least the surface of the plate-like body hit by the hitting body.

Therefore, according to the fourth aspect of the present invention, the vibration when the cymbal is hit is also absorbed by the cushioning surface, so that the hitting sound when the cymbal is hit is further reduced. And the contact sound when hitting with a hitting body such as a stick can be reduced.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a cymbal according to the present invention will be described in detail with reference to the accompanying drawings.

In the following description, the case where the cymbal according to the present invention is configured as the electronic cymbal 10 will be mainly described, but the case where the cushioning double-sided tape 20 and the vibration sensor 22 are removed from the electronic cymbal 10 is described. It is equivalent to a practice cymbal.

FIG. 1 is a schematic structural perspective view showing an electronic cymbal as a first embodiment of a cymbal according to the present invention. FIG. 2 is a partial sectional view taken along line II-II of FIG. FIG. 3 is a partial sectional view taken along line III-III in FIG. 1.

The electronic cymbal 10 is entirely formed as a thin disk (for example, about 1 mm) substantially disk-shaped, that is, a substantially circular flat plate-shaped body made of a metal material such as iron. A mounting through-hole 16 is formed in the center of the plate-like body in the thickness direction of the plate-shaped body, that is, from the front surface 12 to the back surface 14, and a support rod (shown in FIG. ) Is inserted, and the electronic cymbal 10 is locked and supported by the support rod.

The electronic cymbal 10 has a small-diameter through-hole 18 penetrating substantially in the thickness direction of the plate-like body, that is, from the front surface 12 to the back surface 14 over substantially the entire surface of the plate-like body except the mounting through-hole 16. (In order to make the drawings easier to see, FIG. 1, FIG. 6, FIG. 7, FIG. 11, and FIG.
Although only a part of the through hole 18 is shown in FIG. 4, the through hole 18 is formed throughout the plate-shaped body of the electronic cymbal 10. ).

Here, the size of the through hole 18 is such that a striking body such as a stick for hitting the electronic cymbal 10 does not fall out of the through hole 18 or is caught on the edge of the through hole 18. , For example, several mm in diameter
It is preferably about 5 mm or less.

The shape of the opening of the through hole 18 is not limited to a circular shape, and an arbitrary shape such as an elliptical shape or a polygonal shape can be selected according to manufacturing convenience. 10 front 12 or back 1
The hole ratio of the entire area 4 is preferably, for example, about 15% to 30% from the viewpoint of the effect of suppressing the impact sound described later and securing the strength of the electronic cymbal 10.

Further, near the mounting through-hole 16 on the back surface 14 of the electronic cymbal 10, a double-sided cushioning tape 2 is provided.
A vibration sensor 22 for detecting a striking force due to striking of a striking body such as a stick through 0 is attached. The vibration sensor 22 is connected to the sound source 100 as shown in the block diagram of FIG.

Here, the sound source 100 includes an envelope extraction unit 102 and an analog / digital (A / D) conversion unit 10.
4, a CPU (Central Processing Unit) 106, and a sound source unit 108
It is composed of

In the above configuration, the electronic cymbal 1
When 0 is hit with a hitting body such as a stick, the entire electronic cymbal 10 is formed of a metal material such as iron, so that the hitting body rebounds and the entire cymbal shakes when hitting with a hitting body such as a stick. The feeling of impact, such as the state of the sound, is very close to that of a cymbal as an acoustic instrument.

On the other hand, since a large number of small-diameter through holes 18 are formed in the entire surface of the plate-shaped body of the electronic cymbal 10, the vibration of the entire electronic cymbal 10 when the electronic cymbal 10 is hit with a hitting body such as a stick. The area is reduced, and the vibration wave transmitted through the front surface 12 or the back surface 14 of the electronic cymbal 10 is blocked by the through-hole 18 so that the vibration is dispersed, and the attenuation of the vibration due to the impact is accelerated. As a result, the sound of striking the electronic cymbal 10 is significantly smaller than that of a cymbal as an acoustic instrument.

The impact on the electronic cymbal 10 is as follows.
The vibration sensor 22 detects the vibration, and the vibration sensor output waveform (FIG. 5A) is supplied to the envelope extraction unit 102. Then, the envelope extraction unit 102 shapes the supplied output waveform of the vibration sensor by half-wave rectification, and supplies the shaped envelope waveform (FIG. 5B) to the A / D converter 104.

The A / D converter 104 converts the supplied envelope waveform into a digital signal and supplies the digital signal to the CPU 106.

The CPU 106 detects the maximum value of the output waveform due to the striking from the digital signal supplied from the A / D converter 104, and instructs the tone generator 108 to generate a tone with the detected maximum value as a velocity. Is output.
Then, the sound source unit 10 receives a sound generation instruction from the CPU 106.
8 is a release preset according to the sounding instruction.
Generates musical sound of time and emits it into space.

Therefore, by hitting the electronic cymbal 10 with a hitting body such as a stick, a musical tone can be generated electronically based on the hitting force.

When the cushioning double-sided tape 20 and the vibration sensor 22 are removed from the electronic cymbal 10, musical tones are not generated electronically based on the hitting force. Can be used as cymbals.

When the electronic cymbal 10 is hit with a hitting body such as a stick, vibrations are generated.
6, the front surface 12 and the back surface 14 of the electronic cymbal 10 are concentrically transmitted from the hitting portion, so that the center of the electronic cymbal 10, that is, the mounting through hole 16 is concentric as shown in FIG. When the through holes 18 are arranged,
Vibration when striking the electronic cymbal 10 with a striking body such as a stick, in particular, vibration waves when striking the substantially central portion of the electronic cymbal 10 are efficiently blocked from being transmitted by the through-holes 18, thereby dispersing vibration. As a result, the damping of the vibration due to the impact can be accelerated. As a result, it is possible to more effectively suppress the hitting sound when hit by a hitting body such as a stick.

As a metal material for forming the electronic cymbal 10, it is sufficient that the metal has hardness enough to withstand impact, so that various materials other than iron can be used, for example, tin or zinc. Or an alloy thereof can be used as appropriate.

As a metal material for forming the electronic cymbal 10, phosphor bronze used for a cymbal as an acoustic musical instrument may be used, but a metal material having a lower hardness than phosphor bronze, for example, iron is used. Although the feeling of impact is not inferior to that of phosphor bronze, the volume of the impact sound can be suppressed smaller.

FIG. 7 is a schematic structural perspective view showing an electronic cymbal as a second embodiment of the cymbal according to the present invention, and FIG. 8 is a partial sectional view taken along line VIII-VIII of FIG. It is shown.

In the second embodiment, a cushioning member 200 made of an elastic material such as rubber or synthetic resin is engaged with the outer peripheral portion of the electronic cymbal 10 according to the first embodiment. Only in this point, it is different from the above-described first embodiment.

Here, the mode of engagement between the outer peripheral edge of the electronic cymbal 10 and the buffer member 200 is, as shown in FIG. 8, the surface 12 of the electronic cymbal 10 and the surface 20 of the buffer member 200.
0a may form a predetermined angle α, or may engage such that the surface 12 of the electronic cymbal 10 and the surface 200a of the cushioning member 200 are parallel as shown in FIG. May be.

In the second embodiment, since the outer peripheral edge of the electronic cymbal 10 and the buffer member 200 are engaged, the vibration when the electronic cymbal 10 is hit is also absorbed by the buffer member 22. Therefore, the hitting sound when hitting the electronic cymbal 10 can be further reduced.

In the second embodiment,
Since the outer peripheral edge of the electronic cymbal 10 is protected by the cushioning member 200, the buffering member 200 is not affected by the stick 202 as shown in FIG. Since the impact force due to the impact is absorbed, the deformation of the outer peripheral edge of the electronic cymbal 10 due to the impact can be suppressed.

FIG. 11 is a schematic structural perspective view showing an electronic cymbal as a third embodiment of the cymbal according to the present invention, and FIG. 12 is a partial sectional view taken along line XII-XII in FIG. It is shown.

This third embodiment is an electronic cymbal 1
The first embodiment differs from the first embodiment only in that the sheet 204 is covered on the front surface 12 of the zero.

Here, the sheet 204 has good air permeability,
In addition, the electronic cymbal 10 has flexibility to reduce a contact sound between the electronic cymbal 10 and a hitting body such as a stick when hit by a hitting body such as a stick, and easily breaks even when hit by a hitting body such as a stick. Preference is given to a robust, non-woven material, such as cotton cloth, felt, nylon sheet or polyester sheet.

Further, if the sheet 204 is too thick, it is not preferable because it rebounds when hit with a hitting body such as a stick.

The sheet 2 is attached to the surface of the electronic cymbal 10.
When covering the electronic cymbal 04, the sheet 204 may be adhered or adhered to the surface of the electronic cymbal 10.
It is preferable that the adhesive layer and the adhesive layer also have air permeability.

In the third embodiment, since the vibration when the electronic cymbal 10 is hit is also absorbed by the sheet 204, the hitting sound when the electronic cymbal 10 is hit can be further reduced.

When a flexible sheet is used as the sheet 204, as shown in FIG.
02, the contact sound between the electronic cymbal 10 and the stick 202 at the time of the impact is reduced.

In the third embodiment, not only the front surface 12 of the electronic cymbal 10 may be covered with the sheet 204, but also the back surface 14 of the electronic cymbal 10 may be covered with the sheet 204.

FIG. 14 is a schematic structural perspective view showing an electronic cymbal as a fourth embodiment of the cymbal according to the present invention, and FIG. 15 is a partial sectional view taken along line XV-XV of FIG. It is shown.

In the fourth embodiment, the electronic cymbal 1
The first surface described above is formed only in that the buffer surface 206 is formed by coating an elastic material such as rubber or a synthetic resin on the surface 12 of the zero and the wall surface 18a of the through hole 18 so as not to block the through hole 18. Different from the embodiment.

In the fourth embodiment, since the vibration when the electronic cymbal 10 is hit is also absorbed by the cushioning surface 206, the hitting sound when the electronic cymbal 10 is hit can be further reduced. At the same time, the contact sound between the stick and the buffer surface 206 when hitting with a hitting body such as a stick is reduced.

In the above-described fourth embodiment, as shown in FIG.
When the buffer surface 206 is also formed, the electronic cymbal 1
0 is entirely covered by the buffer surface 206, and the effect of absorbing vibration when the electronic cymbal 10 is struck by the buffer surface 206 becomes more remarkable.

The shape of the electronic cymbal 10 is not limited to a substantially disk shape (substantially circular flat plate shape), but may be an arbitrary shape such as an elliptical shape or a polygonal shape if it is flat. Of course.

[0055]

The present invention is configured as described above, so that it is possible to suppress the generation of a hitting sound when hitting with a stick or the like, but to reduce the feeling of hitting when hitting with a stick or the like. It is close to a cymbal as an acoustic instrument, and has an excellent effect of reducing the sense of incongruity given to a player.
