Description

Technical Field

[0001] The present invention relates to an electronic cymbal capable of detecting a percussion on a striking surface and outputting an electrical signal.

Background Art

[0002] As a conventional electronic percussion instrument, an electronic cymbal, as disclosed in, for example, Patent Document 1, includes a pad portion having a striking surface that can be struck by a player, and a frame portion that supports the back surface side of the pad portion. It was configured with an electronic cymbal main body, a vibration sensor capable of detecting a percussion on the striking surface of the pad portion, and an output cable for outputting a detection signal detected by the vibration sensor to the outside. Then, when the player strikes the striking surface of the electronic cymbal main body with a stick, the vibration sensor can detect and output it to the outside, and it was possible to perform the same performance as an acoustic cymbal.

[0003] Also, as a conventional electronic cymbal, a cymbal having an opening formed at a predetermined position on the striking surface and having a design similar to an effect cymbal in an acoustic instrument has been proposed. In this electronic cymbal, an opening is formed at a predetermined position on the striking surface, and the opening is formed so that the hole diameter expands from the striking surface side toward the back surface side in order to suppress the impression that the thickness of the striking surface is thick. Thereby, it is possible to make the striking surface look thin while reproducing the shape of the effect cymbal having an opening formed on the striking surface, and the design can be improved.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional technology described above, the opening is formed so that the hole diameter expands from the striking surface side to the back side, which allows the striking surface to appear thin while reproducing the shape of an effect cymbal. However, since it is necessary to integrally form and protrude reinforcing parts such as ribs at the edge of the opening, the ribs may be visible from the opening, which could interfere with the impression that the striking surface is thin.

[0006] This invention has been made in view of these circumstances, and its purpose is to provide an electronic cymbal that can reproduce the shape of an effect cymbal with an opening formed on the striking surface, and that can make the striking surface appear thinner while reinforcing the opening edge of the opening. [Means for solving the problem]

[0007] The invention described in claim 1 is an electronic cymbal comprising: a main body having a striking surface that can be struck by a performer and having an opening formed at a predetermined position on the striking surface; a reinforcing portion projecting from the opening edge of the opening on the back side of the main body; and a detection means attached to the main body that can detect striking of the striking surface and output an electrical signal, wherein the reinforcing portion is formed such that the opening edge on the outer side of the main body protrudes more than the opening edge on the central side of the main body.

[0008] The invention described in claim 2 is characterized in that, in the electronic cymbal described in claim 1, the reinforcing portion is formed to protrude in an arc shape along the edge of the opening.

[0009] The invention described in claim 3 is characterized in that, in the electronic cymbal described in claim 1, the reinforcing portion is formed only on the outer edge of the opening edge relative to the main body, and the reinforcing portion does not protrude from the central edge of the opening edge relative to the main body.

[0010] The invention described in claim 4 is characterized in that, in the electronic cymbal described in claim 1, the reinforcing portion is formed to have a continuously decreasing protrusion dimension from the opening edge on the outer edge side of the main body to the opening edge on the central side of the main body.

[0011] The invention described in claim 5 is an electronic cymbal according to claim 1, wherein the main body is configured to have a pad portion on which the striking surface is formed and a frame portion that supports the back side of the pad portion, the opening is formed to penetrate the pad portion and the frame portion, and the reinforcing portion is formed to protrude from the back side of the frame portion.

[0012] The invention described in claim 6 is characterized in that, in the electronic cymbal described in claim 5, the frame portion has a cover member that covers the detection means attached to its bottom surface, and the edge of the cover member and the frame portion around its periphery are formed to be smoothly continuous. [Effects of the Invention]

[0013] According to the invention of claim 1, the reinforcing portion is formed such that the outer edge of the opening relative to the main body protrudes more significantly than the central edge of the opening relative to the main body. This makes it possible to reproduce the shape of an effect cymbal with an opening formed on the striking surface, and to make the striking surface appear thinner while reinforcing the opening edge of the opening.

[0014] According to the invention of claim 2, since the reinforcing portion is formed to protrude in an arc shape along the edge of the opening, the opening edge of the opening can be reinforced over the entire length of the extending direction of the reinforcing portion, and the opening edge can be effectively reinforced.

[0015] According to the invention of claim 3, the reinforcing portion is formed only on the outer edge of the opening relative to the main body, and the reinforcing portion does not protrude from the central opening relative to the main body. Therefore, the opening edge can be reinforced without forming a reinforcing portion that is visible from the opening.

[0016] According to the invention of claim 4, since the reinforcing portion is formed such that the protruding dimension continuously decreases from the opening edge portion on the outer edge side with respect to the main body portion toward the opening edge portion on the central side with respect to the main body portion, the reinforcing portion can be smoothly formed over the extending direction, and while effectively performing the reinforcement, the design property can be further improved.

[0017] According to the invention of claim 5, since the opening portion is formed to penetrate through the pad portion and the frame portion, and the reinforcing portion is formed to protrude on the back surface side of the frame portion, the back surface side of the frame portion that is difficult to be seen through the opening portion can be made to protrude to serve as the reinforcing portion, and while maintaining the design property, the reinforcement can be surely performed.

[0018] According to the invention of claim 6, since the cover member covering the detecting means is attached to the bottom surface of the frame portion, and the edge portion of the cover member and the frame portion at its periphery are smoothly and continuously formed, it is possible to prevent the cover member from being seen through the opening portion from the striking surface side, and to eliminate the protruding portion on the bottom surface side of the main body portion to improve the design property.

Mode for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings As shown in FIGS. 1 to 6, the electronic cymbal according to the present embodiment includes a main body portion 1 having a striking surface F configured by a pad portion 2 and a frame portion 3 and capable of being struck by a performer, a piezoelectric element 4 (detection means) attached to an inner peripheral surface S of the frame portion 3 in the main body portion 1, and a cover member 8

[0021] As shown in Figure 1, the main body 1 is supported at a predetermined height by a support stand T that extends vertically from the stand legs Ta. The main body 1 is composed of a pad section 2 having a striking surface F that can be struck by a performer, and a frame section 3 that supports the back side of the pad section 2. The pad section 2 has multiple openings Ha, and the frame section 3 has multiple openings Hb, and these openings Ha and Hb communicate to form an opening H of the main body 1. In the figure, the symbol L indicates a tightening member for tightening and fixing the main body 1 to the support stand T.

[0022] The pad portion 2 is made of a rubber material or soft resin (in this embodiment, silicone rubber) that can be struck with a stick, and consists of a disc-shaped member with an insertion hole 2a formed at the center through which a support stand T can be inserted, as shown in Figures 10 and 11. The striking surface F formed on the upper surface of the pad portion 2 is composed of a cup portion Fb that bulges out in the center of the pad portion 2, an edge portion Fc formed on the periphery of the pad portion 2, and a bow portion Fa which is the region between the cup portion Fb and the edge portion Fc.

[0023] The frame portion 3 is made of a hard resin or metal (in this embodiment, ABS resin) and consists of a disc-shaped member with an insertion hole 3a formed at the center through which a support stand T can be inserted, as shown in Figures 12 and 13. The main body portion 1 is formed by attaching and integrating the pad portion 2 to the surface of the frame portion 3, and a bulge portion 3b is formed in the center of the main body portion, corresponding to the cup portion Fb of the pad portion 2.

[0024] Furthermore, mounting surfaces Sa for attaching piezoelectric elements 4 are formed on the inner circumferential surface S of the bulging portion 3b in the frame portion 3. As shown in Figures 12 and 13, multiple mounting surfaces Sa (four in this embodiment) are formed along the circumferential direction (circumferential direction) on the inner circumferential surface S of the frame portion 3 in the main body portion 1, and piezoelectric elements 4 are attached to each mounting surface Sa.

[0025] As shown in Figures 14 and 15, the cover member 8 is an annular member with an opening 8a in the center through which a support stand T or the like can be inserted. As shown in Figures 2 and 3, it is attached to the back side of the frame portion 3 to cover the inner circumferential surface S of the bulging portion 3b and to cover a substrate 5 (see Figures 3 to 6) on which a predetermined electrical circuit is formed. This substrate 5 is electrically connected to each piezoelectric element 4, and the detection signals of each piezoelectric element 4 are transmitted to the substrate 5. In this embodiment, as shown in the enlarged view of Figure 3, the edge of the cover member 8 and the frame portion 3 around its periphery are formed smoothly and continuously.

[0026] The piezoelectric element 4, which serves as a vibration sensor (detection means), is attached to a mounting surface Sa formed on the main body 1 (frame 3) via a buffer member D. The sensor is capable of converting vibrations generated by striking the striking surface F into an electrical signal. As shown in Figures 8 and 9, it is configured to have, for example, an upper electrode 4a made of a silver conductor, a lower electrode 4b made of, for example, a brass plate, and a piezoelectric ceramic 4c interposed between the upper electrode 4a and the lower electrode 4b.

[0027] Furthermore, the upper electrode 4a is connected to wiring h1, and the lower electrode 4b is connected to wiring h2. When a performer strikes the striking surface F and vibrations are transmitted to the piezoelectric element 4, the entire structure flexes due to the vibrations, and a voltage corresponding to the amount of flexing is generated. When a voltage is generated in this way, the upper electrode 4a acts as the positive electrode and the lower electrode 4b acts as the negative electrode, causing current to flow through wirings h1 and h2, which is then output as an electrical signal via the circuit board 5 and output cable 6.

[0028] However, although the piezoelectric element 4 generates voltage and outputs an electrical signal by bending in direction b perpendicular to the mounting surface Sa, it has a structure that makes it difficult to bend in direction a parallel to the mounting surface Sa. Therefore, vibration in direction b perpendicular to the mounting surface Sa has a higher output characteristic (output characteristic of higher voltage or higher current) compared to vibration in direction a parallel to the mounting surface Sa.

[0029] Furthermore, the piezoelectric element 4 according to this embodiment has a cushioning member D made of polyurethane foam or the like attached to its bottom surface. As shown in Figure 9, the surface of the cushioning member D is attached to the mounting surface Sa with an adhesive or the like, while keeping it in close contact with the mounting surface Sa. The cushioning member D is formed in a cylindrical shape and, as shown in Figure 9, has an outer diameter smaller than the outer diameter of the piezoelectric element 4 (preferably about 67% of the diameter of the piezoelectric element, which acts as a node in the vibration of the piezoelectric element 4), thereby ensuring that the deflection of the piezoelectric element 4 due to vibration is maintained.

[0030] Furthermore, an edge sensor E is attached to the periphery of the surface side of the frame portion 3, enabling detection of impacts to the edge portion Fc of the pad portion 2. Similar to the piezoelectric element 4, the edge sensor E is electrically connected to the substrate 5 via wiring, and a detection signal is transmitted to the substrate 5. The output cable 6 is connected to the piezoelectric element 4 (vibration sensor) and the edge sensor E via the substrate 5, and is capable of outputting the detection signals detected by the piezoelectric element 4 and the edge sensor E to the outside. The output cable 6 has an output jack J at its tip, allowing connection to an external signal processing device (not shown).

[0031] When the performer strikes the striking surface F of the pad section 2 with a stick, causing the main body section 1 to vibrate, the piezoelectric element 4 detects the strength of the strike, and an electrical signal corresponding to that strength is output to an external signal processing device (not shown) via the output cable 6. Depending on the on / off state of the edge sensor E, a strike to the edge section Fc is identified, and if a strike is detected when the edge sensor E is off, it is determined that the strike occurred to the bow section Fa or the cup section Fb, and a predetermined musical tone is output.

[0032] As shown in Figures 3 and 4, the shaft sleeve 7 is made of a cylindrical elastic member (rubber in this embodiment) with an insertion hole formed in its center. The shaft sleeve 7 is interposed between the frame portion 3 and the support stand T within the insertion hole 3a of the frame portion 3, thereby suppressing the transmission of vibrations generated by striking the main body portion 1 to the support stand T.

[0033] As shown in Figures 6 and 7, the mounting surface Sa consists of a surface that is inclined vertically β from a horizontal plane (a plane including the horizontal direction α) toward the center of the main body 1, and the piezoelectric elements 4 are mounted at equal intervals in a concentric circle around the central axis C of the main body 1 (see Figures 3 and 7). In other words, since the inner circumferential surface S formed on the frame portion 3 of the main body 1 is formed in the shape of a frustoconical pyramid, multiple (four in this embodiment) mounting surfaces Sa are formed at equal intervals along the circumferential direction centered on the central axis C on the inner circumferential surface S, and piezoelectric elements 4 are mounted concentrically on each mounting surface Sa.

[0034] Furthermore, if the shape of the main body 1, including a predetermined region (a predetermined region on the inner or outer circumferential surface), is considered as a virtual cone shape, then multiple mounting surfaces Sa are formed concentrically around the central axis C on the side surface of the virtual cone shape (a sector-shaped surface in the unfolded view, the same applies hereinafter). Moreover, each mounting surface Sa consists of a surface inclined at a predetermined angle from the horizontal plane in the vertical direction β toward the center of the frame 3 in the main body 1. As a result, the piezoelectric elements 4 can be arranged three-dimensionally (three dimensions composed of the horizontal direction α and the vertical direction β), and the piezoelectric elements 4 can be sufficiently deflected by vibrations in either the horizontal direction α or the vertical direction β. This makes it possible to output electrical signals well and uniformly in response to vibrations in both the horizontal direction α and the vertical direction β accompanying the striking of the striking surface F.

[0035] Furthermore, if the shape centered on the central axis C, which includes a predetermined area of ​​the main body 1, is considered as a virtual cone shape, then multiple mounting surfaces Sa are formed concentrically around the central axis C on the side surface of the virtual cone shape (four in this embodiment). In this embodiment, the mounting surfaces Sa are formed along the circumferential direction on the inner circumferential surface S of the frame portion 3 of the main body 1, and as shown in Figures 6 and 7, they consist of a plane (flat surface) corresponding to the mounting portion of the piezoelectric element 4 (buffer member D in this embodiment), and as shown in Figures 5 and 6, they have substantially the same shape (circular shape) and dimensions (diameter) as the outer shape of the piezoelectric element 4. Note that the piezoelectric element 4 is not limited to having a circular outer shape; it may also have an elliptical or rectangular shape, and even in that case, the mounting surface Sa has substantially the same shape as the outer shape of the piezoelectric element 4.

[0036] In this embodiment, the electronic cymbal has a design similar to an effect cymbal in an acoustic instrument, by forming an opening H at a predetermined position on the striking surface F. This opening H is formed by aligning an opening Ha formed in the pad portion 2 with an opening Hb formed in the frame portion 3, and penetrates from the surface (striking surface F of the pad portion 2) to the back surface (back surface of the frame portion 3) of the main body portion 1, and is formed to widen in diameter from the striking surface F side to the back surface side.

[0037] Furthermore, as shown in Figure 3, the back side of the opening H (opening Hb formed in the frame portion 3) of the electronic cymbal according to this embodiment is provided with a reinforcing portion G that protrudes from the opening edge of the opening H. This reinforcing portion G consists of a rib integrally formed on the periphery of the opening Hb in the frame portion 3, and as shown in Figures 3 and 5-7, the opening edge on the outer edge side (outer diameter side) relative to the main body portion 1 protrudes more than the opening edge on the central side (inner diameter side) relative to the main body portion 1.

[0038] Furthermore, as shown in Figures 3 and 5-7, the reinforcing portion G according to this embodiment is formed to protrude in an arc shape along the edge of the opening H (opening Hb of the frame portion 3), and the protruding dimension is continuously reduced from the opening edge on the outer edge side relative to the main body portion 1 to the opening edge on the central side relative to the main body portion 1 (the protruding dimension gradually decreases from the outer diameter side to the inner diameter side).

[0039] According to this embodiment, the reinforcing portion G is formed such that the outer edge of the opening protrudes more significantly from the central opening edge relative to the main body 1 than from the central opening edge relative to the main body 1. This makes it possible to reproduce the shape of an effect cymbal with an opening H formed in the striking surface F, and to make the striking surface F appear thinner while reinforcing the opening edge of the opening H. In other words, the main body 1, supported at a predetermined height by the support stand T, is easily visible on the inner diameter side through the opening H, while the outer diameter side is difficult to see. Therefore, it is possible to suppress the protrusion dimension of the outer edge (inner diameter side) of the reinforcing portion G while securing the protrusion dimension on the central side (outer diameter side), thereby effectively reinforcing the opening edge while making the striking surface F appear thinner.

[0040] Furthermore, since the reinforcing portion G according to this embodiment is formed to protrude in an arc shape along the edge of the opening H, it can reinforce the opening edge of the opening H over the entire extension direction of the reinforcing portion G, thereby effectively reinforcing the opening edge. Moreover, since the reinforcing portion G according to this embodiment is formed with a continuously decreasing protrusion dimension from the opening edge on the outer edge side relative to the main body 1 to the opening edge on the central side relative to the main body 1, the reinforcing portion G can be formed smoothly over the extension direction, thereby effectively reinforcing while further improving the design.

[0041] Furthermore, in this embodiment, the opening H is formed to penetrate both the pad portion 2 and the frame portion 3, and the reinforcing portion G is formed to protrude from the back side of the frame portion 3. Therefore, the back side of the frame portion 3, which is difficult to see through the opening H, can be made to protrude and serve as the reinforcing portion, ensuring reliable reinforcement while maintaining aesthetic appeal. In addition, the frame portion 3 has a cover member 8 attached to its bottom surface to cover the piezoelectric element (detection means), and the edge of the cover member 8 and the frame portion 3 around its periphery are formed to be smoothly continuous. This prevents the cover member 8 from being visible through the opening H from the striking surface F side, and also eliminates the protruding portion on the bottom side of the main body portion 1, improving aesthetic appeal.

[0042] In this embodiment, the mounting surface Sa consists of a surface inclined vertically β from a horizontal plane (a plane including the horizontal direction α) toward the center of the main body 1, and the piezoelectric elements 4 are mounted concentrically at equal intervals around the central axis C of the main body 1. Therefore, even if the striking surface F is struck from any direction, the piezoelectric elements 4 can reliably and stably convert the impact into an electrical signal and output it.

[0043] Furthermore, if three or more piezoelectric elements 4 according to this embodiment are mounted concentrically at equal intervals around the central axis C of the main body 1, the piezoelectric elements 4 can stably convert the impact on the striking surface F into an electrical signal and output it uniformly for impacts in various directions. Moreover, since the mounting surface Sa according to this embodiment is provided along the circumferential direction on the outer or inner circumferential surface of the main body 1, the piezoelectric elements 4 can receive vibrations caused by the impact on the striking surface F more uniformly over the entire circumference of the striking surface F, thereby suppressing variations in the output of the electrical signal due to differences in the striking location.

[0044] Furthermore, the mounting surface Sa according to this embodiment is formed along the circumferential direction on the outer or inner circumferential surface of the main body 1 and consists of a plane (flat surface) corresponding to the mounting portion (buffer member D) of the piezoelectric element 4. Therefore, the piezoelectric element 4 can be fixed more stably to the mounting surface Sa compared to fixing it to a curved surface. Note that the mounting surface Sa is not limited to a plane, but may also be a curved surface forming the inner circumferential surface S (or outer circumferential surface).

[0045] In addition, since the mounting surface Sa according to this embodiment has substantially the same shape and dimensions as the outer shape of the piezoelectric element 4, the mounting position of the piezoelectric element 4 relative to the inner circumferential surface S of the main body 1 can be accurately determined during the installation of the piezoelectric element 4, thereby improving the positioning accuracy of the piezoelectric element 4. In other words, by mounting the piezoelectric element 4 in accordance with the mounting surface Sa, the positioning of the piezoelectric element 4 is performed naturally, thereby improving positioning accuracy.

[0046] Furthermore, in this embodiment, the piezoelectric element 4 is fitted with a cushioning member D, and is attached to the mounting surface Sa with the cushioning member D in contact with it, thus preventing damage to the piezoelectric element 4 due to vibrations caused by striking. The cushioning member D only needs to have cushioning properties and be attachable to the bottom surface of the piezoelectric element 4; its material and shape are not limited.

[0047] Although this embodiment has been described above, the present invention is not limited thereto. For example, as shown in Figure 16, the reinforcing portion G may be formed only on the outer edge (outer diameter side) of the opening edge relative to the main body 1, and the reinforcing portion G may not be formed protruding from the central (inner diameter side) of the opening edge relative to the main body 1. In this case, the opening edge can be reinforced without forming a reinforcing portion G that is visible from the opening H.

[0048] Furthermore, as shown in Figure 17, the reinforcing portion G may be formed only on the outer edge (outer diameter side) of the opening edge relative to the main body portion 1, and the reinforcing portion G may not protrude from the central (inner diameter side) opening edge relative to the main body portion 1, and the reinforcing portion G may be formed along the circumferential direction of the main body portion 1 (frame portion 3). Moreover, the reinforcing portion G is not limited to having an inverted triangular cross-sectional shape, but may be a rib with other cross-sectional shapes such as a rectangle or a U-shape.

[0049] Furthermore, the buffer member D is not limited to a cylindrical shape as in the above embodiment, but may also be annular in shape, as shown in Figures 21 and 22. In such annular buffer member D, the back surface Db is attached to the bottom surface (lower electrode 4b) of the piezoelectric element 4 with an adhesive, and the front surface Da is attached to the mounting surface Sa with an adhesive. The annular buffer member D has an annular shape in which its outer diameter t1 is approximately equal to the outer diameter of the piezoelectric element 4. This allows the piezoelectric element 4 to follow the deflection of the main body 1 well while suppressing excessive free vibration of the piezoelectric element 4 itself due to impact, thereby ensuring the voltage of the output electrical signal while accelerating attenuation and preventing false sounds.

[0050] However, it is preferable that the inner diameter t2 of the hollow portion inside the annular cushioning member D is 60 to 80% of the outer diameter t1, and most preferably 70% of the inner diameter t2 of the hollow portion inside the annular cushioning member D is 70% of the outer diameter t1. In other embodiments of the annular cushioning member D, the surface Da that is in close contact with the mounting surface Sa is a flat surface, but it may also be a surface Da with a slit formed over part or the entire circumference, or the ratio of the inner diameter t2 to the outer diameter t1 may be a different ratio.

[0051] In this embodiment, the main body 1 is composed of a pad portion 2 and a frame portion 3, and a mounting surface Sa is formed on the inner circumferential surface S of the frame portion 3. However, the mounting surface may be formed on the inner circumferential surface of a single main body 1. Furthermore, in this embodiment, a piezoelectric element 4 is used to detect the impact on the striking surface F and output an electrical signal. However, other types of vibration sensors may be used to detect vibrations caused by impact. [Industrial applicability]

[0052] If an electronic cymbal has a reinforced section formed where the outer edge of the opening protrudes more significantly from the central edge of the main body than the central edge of the opening, then this can be applied to cymbals with different external shapes or those with added functions.
