　以下、図１～６を参照して本発明の第一実施形態について説明する。
　図１，２に示すように、第一実施形態に係るシンバル１は、厚さが薄い円盤状に形成され、打撃されることで放射音を発生する打楽器である。本実施形態のシンバル１は、金属材料（例えば銅、錫、銀の合金など）で形成されている。なお、シンバル１は、金属材料に限らず、剛性が高い樹脂材料（例えばポリプロピレン（ＰＰ）やポリアミド（ＰＡ））など任意の材料によって形成されてもよい。 [First Embodiment]
Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 to 6.
As shown in FIGS. 1 and 2, the cymbal 1 according to the first embodiment is a percussion instrument that is formed in a thin disk shape and generates a radiant sound when hit. The cymbal 1 of the present embodiment is made of a metal material (for example, an alloy of copper, tin, silver, etc.). The cymbal 1 is not limited to a metal material, and may be formed of any material such as a highly rigid resin material (for example, polypropylene (PP) or polyamide (PA)).
　本実施形態のシンバル１は、カップ部１１と、ボウ部１２と、を有する。カップ部１１は、曲率が大きな椀状あるいは半球状に形成されている。ボウ部１２は、カップ部１１の外周縁に一体に形成され、カップ部１１よりも曲率が小さい椀状あるいは円盤状に形成されている。ボウ部１２の外周縁は、シンバル１のエッジ１３を構成している。カップ部１１及びボウ部１２は、いずれもシンバル１の厚さ方向の一方側（図２において上側）に膨らむように形成されている。以下の説明では、カップ部１１やボウ部１２が膨らむ側の面をシンバル１の表面１ａと呼び、カップ部１１やボウ部１２が窪む側の面をシンバル１の裏面１ｂと呼ぶ。 The cymbal 1 of the present embodiment has a cup portion 11 and a bow portion 12. The cup portion 11 is formed in a bowl shape or a hemispherical shape having a large curvature. The bow portion 12 is integrally formed on the outer peripheral edge of the cup portion 11 and is formed in a bowl shape or a disk shape having a smaller curvature than the cup portion 11. The outer peripheral edge of the bow portion 12 constitutes the edge 13 of the cymbal 1. Both the cup portion 11 and the bow portion 12 are formed so as to bulge toward one side (upper side in FIG. 2) of the cymbal 1 in the thickness direction. In the following description, the surface on the side where the cup portion 11 and the bow portion 12 swell is referred to as the surface 1a of the cymbal 1, and the surface on the side where the cup portion 11 and the bow portion 12 are recessed is referred to as the back surface 1b of the cymbal 1.
　シンバル１の中央Ｃ（カップ部１１の中央Ｃ）の部分には、シンバル１の厚さ方向（図１において紙面に直交する方向）に貫通するホール１４が形成されている。ホール１４に図示しない支持具を通すことで、支持具によってシンバル１を支持することができる。 A hole 14 penetrating the cymbal 1 in the thickness direction (direction orthogonal to the paper surface in FIG. 1) is formed in the portion of the cymbal 1 at the center C (center C of the cup portion 11). By passing a support (not shown) through the hole 14, the cymbal 1 can be supported by the support.
　本実施形態に係るシンバル１は、第一部分２と、第二部分３と、第三部分４と、を備える。 The cymbal 1 according to the present embodiment includes a first portion 2, a second portion 3, and a third portion 4.
　第一部分２は、シンバル１の中央Ｃを中心とする円弧状に形成されている。本実施形態において、シンバル１の中央Ｃを中心とする第一部分２の角度範囲は３６０度である。すなわち、第一部分２はシンバル１の中央Ｃを中心とする円環状に形成されている。第一部分２は、シンバル１の他の部分（主に後述する第二部分３及び第三部分４）よりも剛性が低い低剛性部である。 The first part 2 is formed in an arc shape centered on the center C of the cymbal 1. In the present embodiment, the angle range of the first portion 2 centered on the center C of the cymbal 1 is 360 degrees. That is, the first portion 2 is formed in an annular shape centered on the center C of the cymbal 1. The first portion 2 is a low-rigidity portion having a lower rigidity than the other portions of the cymbal 1 (mainly the second portion 3 and the third portion 4 described later).
　第一部分２は、シンバル１の径方向において、シンバル１の中央Ｃよりも外側に離れて位置し、かつ、シンバル１のエッジ１３よりも内側に離れて位置している。本実施形態において、第一部分２は、シンバル１の径方向においてカップ部１１の外周縁よりも外側に離れたボウ部１２の領域に形成されている。ボウ部１２における第一部分２の形成領域は、例えば、シンバル１の径方向において、カップ部１１の外周縁から外側に１０ｍｍ離れた内側位置ＩＰと、エッジ１３から内側に１０ｍｍ離れた外側位置ＯＰとの間の領域であってよい。シンバル１の径方向における第一部分２の幅寸法Ｗは、例えば１０ｍｍ以上であってよい。 The first portion 2 is located outward from the center C of the cymbal 1 and away from the edge 13 of the cymbal 1 in the radial direction of the cymbal 1. In the present embodiment, the first portion 2 is formed in the region of the bow portion 12 which is separated from the outer peripheral edge of the cup portion 11 in the radial direction of the cymbal 1. The forming region of the first portion 2 in the bow portion 12 is, for example, an inner position IP 10 mm outward from the outer peripheral edge of the cup portion 11 and an outer position OP 10 mm inward from the edge 13 in the radial direction of the cymbal 1. It may be the area between. The width dimension W of the first portion 2 in the radial direction of the cymbal 1 may be, for example, 10 mm or more.
　第二、第三部分３，４の剛性は、第一部分２の剛性よりも高い高剛性部である。第二部分３は、シンバル１の径方向において第一部分２の内側に接続されている。第二部分３は、シンバル１の径方向においてシンバル１の中央Ｃから第一部分２に至るシンバル１の部位である。すなわち、第二部分３はカップ部１１及びボウ部１２の両方を含む。一方、第三部分４は、シンバル１の径方向において第一部分２の外側に接続されている。第三部分４は、シンバル１の径方向においてシンバル１のエッジ１３から第一部分２に至るシンバル１（特にボウ部１２）の部位である。 The rigidity of the second and third parts 3 and 4 is a high rigidity part higher than the rigidity of the first part 2. The second portion 3 is connected to the inside of the first portion 2 in the radial direction of the cymbal 1. The second portion 3 is a portion of the cymbal 1 extending from the center C of the cymbal 1 to the first portion 2 in the radial direction of the cymbal 1. That is, the second portion 3 includes both the cup portion 11 and the bow portion 12. On the other hand, the third portion 4 is connected to the outside of the first portion 2 in the radial direction of the cymbal 1. The third portion 4 is a portion of the cymbal 1 (particularly the bow portion 12) extending from the edge 13 of the cymbal 1 to the first portion 2 in the radial direction of the cymbal 1.
　図２，３に示すように、本実施形態の第一部分２は、シンバル１に形成された溝２１によって構成されている。本実施形態の溝２１は、シンバル１の表面１ａに形成されている。なお、第一部分２を構成する溝２１は、例えばシンバル１の裏面１ｂのみに形成されてもよいし、シンバル１の表面１ａ及び裏面１ｂの両方に形成されてもよい。
　溝２１は、シンバル１の周方向に直交する断面において矩形状に形成されている。このため、シンバル１の厚さ方向における溝２１の深さ寸法及びこれに対応する第一部分２の厚さ寸法Ｔ１は、シンバル１の径方向において一定となっている。 As shown in FIGS. 2 and 3, the first portion 2 of the present embodiment is composed of a groove 21 formed in the cymbal 1. The groove 21 of the present embodiment is formed on the surface 1a of the cymbal 1. The groove 21 constituting the first portion 2 may be formed only on the back surface 1b of the cymbal 1, for example, or may be formed on both the front surface 1a and the back surface 1b of the cymbal 1.
The groove 21 is formed in a rectangular shape in a cross section orthogonal to the circumferential direction of the cymbal 1. Therefore, the depth dimension of the groove 21 in the thickness direction of the cymbal 1 and the corresponding thickness dimension T1 of the first portion 2 are constant in the radial direction of the cymbal 1.
　第一部分２が溝２１によって構成されることで、第一部分２の厚さ寸法Ｔ１は、第二部分３及び第三部分４の厚さ寸法Ｔ０よりも小さくなっている。第一部分２の厚さ寸法Ｔ１は、例えば０．１ｍｍ以上であってよい。また、第二部分３及び第三部分４の厚さ寸法Ｔ０に対する第一部分２の厚さ寸法Ｔ１の比率（Ｔ１／Ｔ０）は、例えば０．８以下であってよい。 Since the first portion 2 is composed of the groove 21, the thickness dimension T1 of the first portion 2 is smaller than the thickness dimension T0 of the second portion 3 and the third portion 4. The thickness dimension T1 of the first portion 2 may be, for example, 0.1 mm or more. Further, the ratio (T1 / T0) of the thickness dimension T1 of the first portion 2 to the thickness dimension T0 of the second portion 3 and the third portion 4 may be, for example, 0.8 or less.
　以上のように構成されるシンバル１は、第二、第三部分３，４の間に第二、第三部分３，４よりも剛性が低い第一部分２を有することで、第一部分２を節として第二部分３及び第三部分４が互いに独立して振動する自由度を持つ。すなわち、図４に示すように、シンバル１を、剛体である第二部分３と第三部分４とをばね２３及びダンパー２４によってつないだ運動モデルと見なすことができる。このため、当該シンバル１を打撃した際（図４において外力Ｆをシンバル１に入力した際）には、第一部分２（ばね２３及びダンパー２４）が伸縮することで、第二部分３と第三部分４とを互いに独立して振動させることができる。 The cymbal 1 configured as described above has a first portion 2 having a lower rigidity than the second and third portions 3 and 4 between the second and third portions 3 and 4, so that the first portion 2 is knotted. As a result, the second part 3 and the third part 4 have a degree of freedom to vibrate independently of each other. That is, as shown in FIG. 4, the cymbal 1 can be regarded as a motion model in which a rigid second portion 3 and a third portion 4 are connected by a spring 23 and a damper 24. Therefore, when the cymbal 1 is hit (when an external force F is input to the cymbal 1 in FIG. 4), the first portion 2 (spring 23 and damper 24) expands and contracts, so that the second portion 3 and the third portion 3 and the third portion 3 and the third portion 2 expand and contract. The portion 4 and the portion 4 can be vibrated independently of each other.
　本実施形態のシンバル１（実施例のシンバル１）は、図５の実線で示す振動の周波数特性を有する。図５の破線は、比較例のシンバルの振動の周波数特性を示している。比較例のシンバルは、第一部分２がないシンバル、すなわち溝２１を形成していないシンバルである。第一部分２を除く比較例のシンバルの形状や厚さなどは、実施例のシンバル１と同様である。以下の説明では、実施例のシンバル１を単に「実施例」と呼び、比較例のシンバルを単に「比較例」と呼ぶことがある。 The cymbal 1 of the present embodiment (the cymbal 1 of the embodiment) has the frequency characteristic of the vibration shown by the solid line in FIG. The broken line in FIG. 5 shows the frequency characteristics of the vibration of the cymbal of the comparative example. The cymbal of the comparative example is a cymbal without the first part 2, that is, a cymbal that does not form the groove 21. The shape, thickness, and the like of the cymbals of the comparative example except for the first part 2 are the same as those of the cymbals 1 of the embodiment. In the following description, the cymbal 1 of the embodiment may be simply referred to as “example”, and the cymbal of the comparative example may be simply referred to as “comparative example”.
　図５に示すように、実施例及び比較例は、いずれも複数のピーク周波数を有する。ただし、実施例における一次のピーク周波数ＦＰ１や二次のピーク周波数ＦＰ２は、それぞれ比較例における一次のピーク周波数ＦＣ１や二次のピーク周波数ＦＣ２よりも低い。実施例のシンバル１では、低次のピーク周波数が比較例のシンバルよりも低いため、比較例のシンバルよりも低ピッチの音が発生する。 As shown in FIG. 5, both the examples and the comparative examples have a plurality of peak frequencies. However, the primary peak frequency FP1 and the secondary peak frequency FP2 in the examples are lower than the primary peak frequency FC1 and the secondary peak frequency FC2 in the comparative examples, respectively. In the cymbal 1 of the embodiment, since the low-order peak frequency is lower than that of the cymbal of the comparative example, a sound having a lower pitch than that of the cymbal of the comparative example is generated.
　また、比較的高い周波数帯域（図５においてｆ１からｆ２までの周波数帯域）では、実施例におけるピーク周波数の数（１３個）が、比較例におけるピーク周波数の数（１０個）よりも多い。また、同周波数帯域では、実施例におけるピーク周波数の音圧レベルが、比較例におけるピーク周波数の音圧レベルよりも大きい。これにより、実施例のシンバル１では、比較例のシンバルよりも大きな音が発生する。 Further, in a relatively high frequency band (frequency band from f1 to f2 in FIG. 5), the number of peak frequencies (13) in the examples is larger than the number of peak frequencies (10) in the comparative example. Further, in the same frequency band, the sound pressure level of the peak frequency in the example is larger than the sound pressure level of the peak frequency in the comparative example. As a result, the cymbal 1 of the embodiment produces a louder sound than the cymbal of the comparative example.
　次に、本実施形態のシンバル１の機能性評価について図６を参照して説明する。本実施形態のシンバル１の機能性評価は、数人の被験者が、本実施形態のシンバル１（実施例のシンバル１）の打音と比較例のシンバルの打音とを聞き比べることで行われる。比較例のシンバルは、第一部分２が無い点を除いて実施例のシンバル１と同じである。被験者は、比較例のシンバルの打音を基準（図６における原点Ｏ）として、実施例のシンバル１を打撃した際に発生する音のピッチの高さ、及び、音の複雑さ・豊かさを評価する。 Next, the functional evaluation of the cymbal 1 of the present embodiment will be described with reference to FIG. The functional evaluation of the cymbal 1 of the present embodiment is performed by several subjects listening to and comparing the tapping sound of the cymbal 1 of the present embodiment (cymbal 1 of the embodiment) with the tapping sound of the cymbal of the comparative example. .. The cymbal of the comparative example is the same as the cymbal 1 of the embodiment except that the first part 2 is absent. Using the hitting sound of the cymbal of the comparative example as a reference (origin O in FIG. 6), the subject examines the pitch height of the sound generated when the cymbal 1 of the embodiment is hit, and the complexity and richness of the sound. evaluate.
　図６は、四人の被験者が実施例のシンバル１の音のピッチの高さ及び音の複雑さ、豊かさを評価した結果を示している。図６の評価結果によれば、実施例のシンバル１の音は、比較例のシンバルの音よりも、低ピッチであり、かつ、複雑で豊かな音を出していると評価されている。 FIG. 6 shows the results of evaluation of the pitch pitch, the complexity, and the richness of the sound of the cymbal 1 of the example by four subjects. According to the evaluation result of FIG. 6, it is evaluated that the sound of the cymbal 1 of the embodiment has a lower pitch than the sound of the cymbal of the comparative example, and produces a complicated and rich sound.
　以上説明したように、本実施形態に係るシンバル１は、シンバル１の中央Ｃを中心とする円弧状に形成された第一部分２と、シンバル１の径方向において第一部分２の内側及び外側に接続され、第一部分２よりも剛性が高い第二部分３及び第三部分４と、を有する。このため、シンバル１を打撃した際には、第二、第三部分３，４の間で振動の位相ずれを発生させて、シンバル１全体を複雑に振動させることができる。これにより、第一部分２が無く、剛性が一様である通常のシンバル（前述した比較例のシンバル）と比較して、より複雑で豊かな音を発生させることができる。 As described above, the cymbal 1 according to the present embodiment is connected to the first portion 2 formed in an arc shape centered on the center C of the cymbal 1 and to the inside and outside of the first portion 2 in the radial direction of the cymbal 1. It has a second portion 3 and a third portion 4 which are more rigid than the first portion 2. Therefore, when the cymbal 1 is hit, a phase shift of vibration is generated between the second and third portions 3 and 4, and the entire cymbal 1 can be vibrated in a complicated manner. As a result, a more complicated and rich sound can be generated as compared with a normal cymbal (the cymbal of the above-mentioned comparative example) having no first portion 2 and having uniform rigidity.
　さらに、本実施形態のシンバル１を打撃した際には、剛性が低い第一部分２では剛性が高いシンバル１の他の部分よりも大きな振幅で振動する。また、第一部分２における大きな振動振幅に伴って第二、第三部分３，４も大きな振幅で振動する。また、シンバル１における振動モードの数（ピーク周波数の数）が通常のシンバル１よりも多くなる。これにより、通常のシンバル１と比較して、より大きな音を発生させることができる。 Further, when the cymbal 1 of the present embodiment is hit, the first portion 2 having low rigidity vibrates with a larger amplitude than the other portions of the cymbal 1 having high rigidity. Further, the second and third portions 3 and 4 also vibrate with a large amplitude in accordance with the large vibration amplitude in the first portion 2. Further, the number of vibration modes (number of peak frequencies) in the cymbal 1 is larger than that in the normal cymbal 1. As a result, a louder sound can be generated as compared with the normal cymbal 1.
　また、本実施形態のシンバル１では、第一部分２の剛性が第二、第三部分３，４よりも低いことで、第一部分２における低次のピーク周波数が、第二、第三部分３，４における低次のピーク周波数よりも低くなる。このため、シンバル１全体における低次のピーク周波数が通常のシンバル１よりも低下する。これにより、通常のシンバル１と比較して、より低ピッチの音を発生させることができる。 Further, in the cymbal 1 of the present embodiment, the rigidity of the first portion 2 is lower than that of the second and third portions 3 and 4, so that the low-order peak frequency in the first portion 2 is the second and third portions 3 and 4. It is lower than the low-order peak frequency at 4. Therefore, the low-order peak frequency of the entire cymbal 1 is lower than that of the normal cymbal 1. As a result, a sound having a lower pitch can be generated as compared with the normal cymbal 1.
　また、本実施形態のシンバル１では、剛性が低い第一部分２が、シンバル１の中央Ｃを中心とする円環状に形成されている。このため、剛性が高い第二部分３と第三部分４とが第一部分２のみを介して互いに接続される。これにより、第二、第三部分３，４を相対的により大きく振動させることができる。したがって、さらに大きな音を発生させることができる。 Further, in the cymbal 1 of the present embodiment, the first portion 2 having low rigidity is formed in an annular shape centered on the center C of the cymbal 1. Therefore, the second portion 3 and the third portion 4 having high rigidity are connected to each other only via the first portion 2. As a result, the second and third portions 3 and 4 can be vibrated relatively more. Therefore, a louder sound can be generated.
　また、本実施形態のシンバル１では、第一部分２の厚さ寸法が、第二、第三部分３，４の厚さ寸法よりも小さい。これにより、シンバル１を単一の材料（例えば金属材料のみ）で形成しても、第一部分２の剛性を第二、第三部分３，４よりも低くすることができる。 Further, in the cymbal 1 of the present embodiment, the thickness dimension of the first portion 2 is smaller than the thickness dimension of the second and third portions 3 and 4. Thereby, even if the cymbal 1 is formed of a single material (for example, only a metal material), the rigidity of the first portion 2 can be made lower than that of the second, third portions 3, 4.
　また、本実施形態のシンバル１において、第一部分２の厚さ寸法Ｔ１を０．１ｍｍ以上とする場合には、シンバル１が打撃などの外力を受けても、第一部分２に亀裂が入ることを抑制することができる。
　また、本実施形態のシンバル１において、第二部分３及び第三部分４の厚さ寸法Ｔ０に対する第一部分２の厚さ寸法Ｔ１の比率を０．８以下とする場合には、第一部分２の剛性を第二、第三部分３，４の剛性よりも明確に低くすることができる。これにより、第二、第三部分３，４の間で第一部分２を確実に伸縮させて、第二、第三部分３，４を確実に互いに独立して振動させることができる。 Further, in the cymbal 1 of the present embodiment, when the thickness dimension T1 of the first portion 2 is 0.1 mm or more, even if the cymbal 1 receives an external force such as an impact, the first portion 2 is cracked. It can be suppressed.
Further, in the cymbal 1 of the present embodiment, when the ratio of the thickness dimension T1 of the first portion 2 to the thickness dimension T0 of the second portion 3 and the third portion 4 is 0.8 or less, the ratio of the thickness dimension T1 of the first portion 2 is set to 0.8 or less. The rigidity can be clearly lower than the rigidity of the second and third portions 3 and 4. As a result, the first portion 2 can be reliably expanded and contracted between the second and third portions 3 and 4, and the second and third portions 3 and 4 can be reliably vibrated independently of each other.
〔第二実施形態〕
　次に、主に図７，８を参照して本発明の第二実施形態について説明する。第二実施形態においては、第一実施形態と同様の構成要素について同一符号を付す等して、その説明を省略する。 [Second Embodiment]
Next, the second embodiment of the present invention will be described mainly with reference to FIGS. 7 and 8. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
　図７に示すように、第二実施形態のシンバル１Ｄは、第一実施形態と同様に、剛性が低い円弧状の第一部分２と、シンバル１Ｄの径方向における第一部分２の両側に接続され、第一部分２よりも剛性が高い第二部分３及び第三部分４を有する。第一部分２は、第一実施形態と同様にシンバル１Ｄの中央Ｃを中心とする円弧状に形成されている。 As shown in FIG. 7, the cymbal 1D of the second embodiment is connected to both sides of the arcuate first portion 2 having low rigidity and the first portion 2 in the radial direction of the cymbal 1D, as in the first embodiment. It has a second portion 3 and a third portion 4 that are more rigid than the first portion 2. The first portion 2 is formed in an arc shape centered on the center C of the cymbal 1D as in the first embodiment.
　ただし、シンバル１Ｄの中央Ｃを中心とする第一部分２の角度範囲θ１は３６０度未満である。図７に例示するシンバル１Ｄでは、第一部分２の角度範囲θ１が２４０度となっている。すなわち、第一部分２は、シンバル１Ｄの周方向の一部にだけ形成されている。 However, the angle range θ1 of the first portion 2 centered on the center C of the cymbal 1D is less than 360 degrees. In the cymbal 1D illustrated in FIG. 7, the angle range θ1 of the first portion 2 is 240 degrees. That is, the first portion 2 is formed only in a part of the cymbal 1D in the circumferential direction.
　第二、第三部分３，４は、第一部分２の角度範囲θ１に対応するシンバル１Ｄの部分にだけ形成される。第二部分３と第三部分４とは、剛性の低い第一部分２だけではなく、シンバル１Ｄのうち周方向において第一部分２が形成されずに剛性が高い部分（図７においてシンバル１Ｄのうち角度範囲θ２の部分５）も介して、互いに接続されている。このため、第二実施形態のシンバル１Ｄでは、第一部分２が円環状に形成される場合と比較して、より複雑な振動態様を実現することができる。 The second, third portions 3 and 4 are formed only in the portion of the cymbal 1D corresponding to the angle range θ1 of the first portion 2. The second portion 3 and the third portion 4 are not only the first portion 2 having low rigidity, but also the portion of the cymbal 1D in which the first portion 2 is not formed in the circumferential direction and the rigidity is high (the angle of the cymbal 1D in FIG. 7). They are also connected to each other via a portion 5) of the range θ2. Therefore, in the cymbal 1D of the second embodiment, a more complicated vibration mode can be realized as compared with the case where the first portion 2 is formed in an annular shape.
　図８は、第二実施形態のシンバル１Ｄの機能性評価の結果を示している。第二実施形態のシンバル１Ｄの機能性評価は、四人の被験者が、第二実施形態のシンバル１Ｄの打音と、第一部分２が無い比較例のシンバルの打音とを聞き比べることで行われる。図８の評価結果によれば、第二実施形態のシンバル１Ｄの音は、比較例のシンバルの音よりも、低ピッチであり、かつ、複雑で豊かな音を出していると評価されている。また、図８の評価結果を図６に示す第一実施形態のシンバル１の評価結果と比べると、第二実施形態のシンバル１Ｄの音は、第一実施形態のシンバル１の音よりも複雑で豊かな音を出していると評価されていることが分かる。 FIG. 8 shows the result of the functional evaluation of the cymbal 1D of the second embodiment. The functional evaluation of the cymbal 1D of the second embodiment is performed by four subjects listening to and comparing the striking sound of the cymbal 1D of the second embodiment with the striking sound of the cymbal of the comparative example without the first part 2. Will be. According to the evaluation result of FIG. 8, it is evaluated that the sound of the cymbal 1D of the second embodiment has a lower pitch than the sound of the cymbal of the comparative example, and produces a complicated and rich sound. .. Further, when the evaluation result of FIG. 8 is compared with the evaluation result of the cymbal 1 of the first embodiment shown in FIG. 6, the sound of the cymbal 1D of the second embodiment is more complicated than the sound of the cymbal 1 of the first embodiment. It can be seen that it is evaluated as producing a rich sound.
　第二実施形態に係るシンバル１Ｄによれば、第一実施形態と同様の効果を奏する。
　また、第二実施形態のシンバル１Ｄでは、シンバル１Ｄの中央Ｃを中心とする第一部分２の角度範囲θ１が３６０度未満である。このため、第二、第三部分３，４がシンバル１Ｄの周方向の一部にだけ形成される。これにより、第一部分２が円環状に形成される場合と比較して、より複雑な振動態様を実現することができる。したがって、第二実施形態のシンバル１Ｄではより複雑で豊かな音を出すことができる。 According to the cymbal 1D according to the second embodiment, the same effect as that of the first embodiment is obtained.
Further, in the cymbal 1D of the second embodiment, the angle range θ1 of the first portion 2 centered on the center C of the cymbal 1D is less than 360 degrees. Therefore, the second and third portions 3 and 4 are formed only in a part of the cymbal 1D in the circumferential direction. Thereby, a more complicated vibration mode can be realized as compared with the case where the first portion 2 is formed in an annular shape. Therefore, the cymbal 1D of the second embodiment can produce a more complicated and rich sound.
　第二実施形態のシンバル１Ｄにおいて、第一部分２の角度範囲θ１は１２０度以上であればよい。第一部分２の角度範囲θ１が１２０度以上であれば、第一部分２の両側に位置する第二、第三部分３，４の大きさを十分に確保することができる。これにより、第二、第三部分３，４が互いに独立して振動する自由度を十分に確保できる。したがって、このようなシンバルでは、第一部分２の角度範囲θ１が１２０度未満である場合と比較して、より確実に複雑で豊かな音、より低ピッチの音、より大きな音を発生させることができる。 In the cymbal 1D of the second embodiment, the angle range θ1 of the first portion 2 may be 120 degrees or more. When the angle range θ1 of the first part 2 is 120 degrees or more, the sizes of the second, third parts 3, and 4 located on both sides of the first part 2 can be sufficiently secured. As a result, the degree of freedom in which the second and third portions 3 and 4 vibrate independently of each other can be sufficiently secured. Therefore, in such a cymbal, it is possible to more reliably generate a complex and rich sound, a lower pitch sound, and a louder sound as compared with the case where the angle range θ1 of the first part 2 is less than 120 degrees. can.
　以上、本発明について詳細に説明したが、本発明は上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。 Although the present invention has been described in detail above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
　本発明のシンバルにおいて、第一部分２を構成する溝２１は、その深さ寸法がシンバルの径方向における溝２１の中央から両端に向かうにしたがって小さくなる形状（例えば断面Ｕ字状や断面Ｖ字状、断面半円状）に形成されてもよい。 In the cymbal of the present invention, the groove 21 constituting the first portion 2 has a shape in which the depth dimension thereof decreases from the center of the groove 21 in the radial direction of the cymbal toward both ends (for example, a U-shaped cross section or a V-shaped cross section). , Semicircular cross section).
　本発明のシンバルでは、例えば第一部分２が第二、第三部分３，４よりも剛性の低い材料によって構成されてもよい。例えば、第二、第三部分３，４が金属材料によって構成され、第一部分２が金属材料よりも剛性の低い樹脂材料によって構成されてもよい。この場合には、例えば、第一部分２の厚さ寸法Ｔ１と第二、第三部分３，４の厚さ寸法Ｔ０とが互いに等しくてもよい。 In the cymbal of the present invention, for example, the first portion 2 may be made of a material having a lower rigidity than the second and third portions 3 and 4. For example, the second and third portions 3 and 4 may be composed of a metal material, and the first portion 2 may be composed of a resin material having a lower rigidity than the metal material. In this case, for example, the thickness dimension T1 of the first portion 2 and the thickness dimension T0 of the second and third portions 3 and 4 may be equal to each other.
　本発明のシンバルは、平面視円形状に限らず、例えば平面視多角形状に形成されてもよい。また、本発明のシンバルにおいて、ボウ部１２は、例えばチャイナシンバルのように厚さ方向において複雑に湾曲していてもよい。また、本発明のシンバルは、カップ部１１を有していなくてもよい。 The cymbal of the present invention is not limited to a circular shape in a plan view, and may be formed in a polygonal shape in a plan view, for example. Further, in the cymbal of the present invention, the bow portion 12 may be complicatedly curved in the thickness direction, for example, like a China cymbal. Further, the cymbal of the present invention does not have to have the cup portion 11.
