Description

Technical Field

[0001] The present invention relates to an electronic cymbal capable of detecting a percussion by a player and outputting the detected detection signal.

Background Art

[0002] Conventional electronic cymbals, as disclosed in, for example, Patent Document 1, are formed in a disk shape and include a frame having an attachment surface formed on the upper surface of the outer edge portion, a cover formed to cover the upper surface of the frame and allowing percussion by a player, and an edge sensor attached to the attachment surface of the frame and detecting percussion against the edge portion of the cover. When a player strikes the striking surface of the cover of the electronic cymbal with a stick, the vibration sensor can detect the strike and output it to the outside, enabling a performance similar to that of an acoustic cymbal.

[0003] Particularly, in conventional electronic cymbals, the attachment surface formed on the outer edge portion of the frame is formed to slope downward more greatly than the inner region surface inside it, and the edge sensor attached to the attachment surface is directed horizontally. This makes it possible to improve the sensitivity to percussion from the horizontal direction at the edge portion of the cover.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the conventional electronic cymbals described above, while it is possible to improve the sensitivity of the cover's edge to lateral strikes by orienting the edge sensor attached to the frame's mounting surface laterally, if the frame's mounting surface is sloped downwards significantly, the thickness of the cover's edge that surrounds the frame must be increased. This results in a design that differs from the thin appearance of an acoustic cymbal, thus degrading its aesthetic appeal.

[0006] The present invention has been made in view of these circumstances, and aims to provide an electronic cymbal that can improve the sensitivity of the edge sensor to lateral tapping, and can also improve the design by suppressing an increase in the thickness dimension of the edge portion of the cover. [Means for solving the problem]

[0008] The invention described in claim 2 is an electronic cymbal comprising: a frame that slopes downward from the center toward the outer edge and has a mounting surface formed on the upper surface of the outer edge and an inner region surface formed inward from the mounting surface; a cover formed to cover the upper surface of the frame and allowing it to be struck by a performer; and an edge sensor attached to the mounting surface formed on the frame and for detecting strikes to the edge of the cover, wherein the frame has a protruding portion formed between the inner region surface and the mounting surface that protrudes upward toward the outer edge from the inner region surface, and the mounting surface slopes downward toward the outer edge at a larger angle than the surface of the cover directly above it.

[0009] The invention described in claim 3 is characterized in that, in the electronic cymbal described in claim 1 or claim 2, the protruding portion has a stepped shape formed between the inner region surface and the mounting surface.

[0010] The invention described in claim 4 is characterized in that, in the electronic cymbal described in claim 1 or claim 2, the protruding portion has a slope shape formed over a predetermined distance between the inner region surface and the mounting surface.

[0011] The invention described in claim 5 is characterized in that, in the electronic cymbal described in claim 1 or claim 2, the frame has a locking portion that protrudes downward on the lower surface of the portion in which the protrusion is formed, and the locking portion locks to the end of the cover.

[0012] The invention described in claim 6 is an electronic cymbal according to claim 1 or claim 2, characterized in that the frame has a convex portion that protrudes downward on the lower surface of the outer edge, and the convex portion fits into a recess formed in the cover. [Effects of the Invention]

[0013] According to the invention of claim 1, the frame has a protruding portion that projects upward from the inner region surface toward the outer edge between the inner region surface and the mounting surface, and the mounting surface is inclined downward toward the outer edge at a larger angle than the inner region surface, thereby improving the sensitivity of the edge sensor to lateral impacts and improving the aesthetic appearance by suppressing an increase in the thickness dimension of the edge portion of the cover.

Modes for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. The electronic cymbal 1 according to this embodiment is capable of detecting strikes made by a performer and outputting the detected detection signal. As shown in Figures 1 to 5, it comprises a frame 2 to which an edge sensor S1, a cup sensor S2, and a vibration sensor S3 are attached, and a cover 3 attached to cover the upper part of the frame 2.

[0021] The cover 3 is made of an elastic material such as silicone rubber or synthetic rubber, and as shown in Figures 2 to 5, it is formed to cover the upper surface of the frame 2, allowing the performer to strike it with a stick. The cover 3 has a central hole 3a formed in the center through which a support stand (not shown) can be inserted, and as shown in Figures 1 and 2, it has a striking surface consisting of a cup portion b formed in the central bulge, an edge portion a formed on the outer edge (periphery), and a bow portion c consisting of the region between the edge portion a and the cup portion b.

[0022] Frame 2 is made of a hard resin such as nylon or ABS, and as shown in Figures 2-5 and 9, it slopes downward from the center towards the outer edge, and has a mounting surface 2c formed on the upper surface of the outer edge and an inner region surface 2d formed inside the mounting surface 2c. An opening is formed in the center of frame 2, and a central edge portion 2a is formed at the edge of the opening. A shaft sleeve 7 is attached to this central edge portion 2a, as shown in Figures 2-5.

[0023] Multiple sensor mounting sections M for attaching vibration sensors S3 are formed on the back surface of the frame 2. These multiple sensor mounting sections M are formed in positions that are rotationally symmetric with respect to the central axis of the frame 2, and each is located on a concentric circle. In addition, screw holes B through which mounting screws N can be inserted are formed on the inside of the sensor mounting sections M on the back surface of the frame 2.

[0024] However, as shown in Figure 10, vibration sensors S3 are attached to each of the multiple sensor mounting sections M on the frame 2. Furthermore, as shown in Figure 7, an annular edge sensor S1 is attached to the mounting surface 2c on the outer edge of the frame 2, and an annular cup sensor S2 is attached to the central part of the frame 2 (the position corresponding to the cup section b of the cover 3). The vibration sensors S3 are capable of detecting vibrations of the frame 2 and detecting impacts to the cover 3.

[0025] Furthermore, as shown in Figure 8, a circuit board 5 with an output cable 8 extending from it is fixed to the back side of the central part of the frame 2. This circuit board 5 is electrically connected to the edge sensor S1, the cup sensor S2, and the vibration sensor S3. When the vibration sensor S3 detects a tap, the detection signal is transmitted to the circuit board 5 and then output to the outside via the output cable 8. In this embodiment, the circuit board 5 is fixed to the frame 2 with a plurality of fixing screws P (see Figure 8), and screw holes D (see Figures 9 and 10) are formed on the back side of the frame 2 through which the fixing screws P can be inserted and screwed.

[0026] Then, when the performer strikes the striking surface of the cover 3 (edge ​​a, cup b, and bow c) with a stick to vibrate the electronic cymbal 1, the vibration sensor S3 detects the strength of the strike, and an electrical signal corresponding to that strength is transmitted to the output cable 8 via the circuit board 5 and output to an external signal processing device (not shown) via the connection jack 9.

[0027] The connection jack 9 according to this embodiment has a first connection jack 9a capable of outputting detection signals from the vibration sensor S3 and the edge sensor S1, and a second connection jack 9b capable of outputting a detection signal from the cup sensor S2. When an external cable (not shown) is connected only to the first connection jack 9a, the detection signals from the vibration sensor S3 and the edge sensor S1 are transmitted to an external signal processing device, and the vibration sensor S3's detection signal makes it possible to detect the impact. However, when an external cable is connected only to the second connection jack 9b, the cup sensor S2's detection signal is transmitted to the external signal processing device, but the vibration sensor S3's detection signal is not transmitted, making it impossible to detect the impact.

[0028] In this embodiment, the connection jack 9 has a first connection jack 9a and a second connection jack 9b that are integrated with a step between them, and in this embodiment in particular, the first connection jack 9a is formed to protrude more than the second connection jack 9b. This allows users to intuitively prioritize connecting the first connection jack 9a to the connection jack 9 when connecting an external cable, and makes it easy to connect the connection jack 9 to an external cable even in dark environments such as a stage.

[0029] Furthermore, the edge sensor S1 is capable of detecting a tap on the edge portion a of the cover 3 and outputting an ON signal, and the cup sensor S2 is capable of detecting a tap on the cup portion b of the cover 3 and outputting an ON signal. As a result, the tap on either the edge portion a or the cup portion b can be identified depending on the ON / OFF state of the edge sensor S1 and the cup sensor S2.

[0030] For example, if the edge sensor S1 and cup sensor S2 are off and the vibration sensor S3 detects a strike, the external signal processing device will determine that the strike occurred on the bow portion c and output a musical tone corresponding to the bow portion c. Conversely, if the edge sensor S1 or cup sensor S2 is on and the vibration sensor S3 detects a strike, the external signal processing device will determine that the strike occurred on the edge portion a or the cup portion b and output an appropriate musical tone corresponding to the strike location.

[0031] Furthermore, a cover member 4 is attached to the back surface of the frame 2 according to this embodiment to cover the vibration sensor S3 and the substrate 5. This cover member 4 is made of a hard resin such as nylon or ABS and is fixed to the back surface of the frame 2 with a plurality of mounting screws N (see Figures 7 and 8). Also, as shown in Figure 7, the cover member 4 has a plurality of accommodating recesses 4a integrally formed in the circumferential direction, and elastic members 6 made of rubber or the like can be accommodated in each of these accommodating recesses 4a.

[0032] As shown in Figure 4, the elastic member 6 consists of a cylindrical member with a recess 6a formed in its center, and a boss portion 2b that protrudes from the frame 2 can be fitted into the recess 6a. Thus, after aligning the lid member 4 with the center of the back side of the frame 2, the lid member 4 is fixed to the frame 2 by inserting and screwing in multiple mounting screws N through the screw holes B (see Figure 10), and as shown in Figure 4, the boss portion 2b fits into the recess 6a of the elastic member 6, providing elastic support. In this embodiment, the lid member 4 is attached without protruding from the frame 2, which improves the aesthetic appearance.

[0033] On the other hand, as shown in Figure 10, the screw hole B in this embodiment is formed inside a virtual circle α connecting the centers of the vibration sensor S3, and as shown in Figure 3, the cover member 4 can be fixedly supported inside the virtual circle α by inserting and screwing in the mounting screw N. The fixing position of the substrate 5 (screw hole D) is also set inside the virtual circle α, similar to the fixing position of the cover member 4 (screw hole B). This prevents vibrations transmitted to the vibration sensor S3 from being hindered by the fixing of the cover member 4 and the substrate 5.

[0034] On the other hand, as shown in Figure 6, the outer edge of the cover 3 is folded back to cover the upper and lower surfaces of the mounting surface 2c of the frame 2, and a pressing portion 3b is formed to protrude at a position facing the edge sensor S1. This allows the pressing portion 3b to press against the edge sensor S1 and output an ON signal when the performer strikes the edge portion a of the cover 3 with a stick.

[0035] In this embodiment, as shown in Figure 6, the frame 2 has a projection 2e that protrudes upward from the inner region surface 2d toward the outer edge (left side in the figure) between the inner region surface 2d and the mounting surface 2c, and the mounting surface 2c is sloped downward toward the outer edge at a larger angle than the inner region surface 2d (angle of inclination of mounting surface 2c > angle of inclination of inner region surface 2d). In other words, the angle of inclination of the mounting surface 2c with respect to the horizontal is greater than the angle of inclination of the inner region surface 2d with respect to the horizontal.

[0036] Similarly, as shown in Figure 6, the frame 2 according to this embodiment has a projection 2e that protrudes upward from the inner region surface 2d toward the outer edge (left side in the figure) between the inner region surface 2d and the mounting surface 2c, and the mounting surface 2c is sloped downward toward the outer edge at a larger angle than the surface of the cover 3 directly above it (angle of inclination of mounting surface 2c > angle of inclination of the surface of the cover 3 located directly above the mounting surface 2c). In other words, the angle of inclination of the mounting surface 2c with respect to the horizontal is greater than the angle of inclination of the surface of the cover 3 directly above the mounting surface 2c with respect to the horizontal.

[0037] The protruding portion 2e according to this embodiment has a stepped shape formed between the inner region surface 2d and the mounting surface 2c, with the starting end of the mounting surface 2c (right end in Figure 6) positioned higher than the end of the inner region surface 2d (left end in Figure 6). This makes it possible to reduce the thickness dimension H of the outer edge of the electronic cymbal 1 (outer edge of the cover 3) even if the downward inclination angle of the mounting surface 2c is increased.

[0038] Furthermore, in this embodiment, the frame 2 has a locking portion 2g that protrudes downward on the lower surface of the portion where the protrusion 2e is formed, and the locking portion 2g is designed to lock with the end portion 3d of the cover 3 (the end portion 3d of the portion that is folded back at the outer edge of the cover 3). This allows the mounting state of the cover 3 to the frame 2 to be maintained, and the portion where the protrusion 2e is formed can be made thicker, thereby improving the rigidity of that portion.

[0039] Furthermore, the frame 2 according to this embodiment has a protrusion 2f that projects downward on the lower surface of its outer edge, and the protrusion 2f is designed to fit into a recess 3c formed in the cover 3. This allows the mounting surface 2c to be accurately positioned by fitting the protrusion 2f into the recess 3c.

[0040] According to this embodiment, the frame 2 has a protruding portion 2e that projects upward from the inner region surface 2d toward the outer edge between the inner region surface 2d and the mounting surface 2c, and the mounting surface 2c is inclined downward toward the outer edge at a larger angle than the inner region surface 2d. As a result, the edge sensor S1 can be directed laterally relative to the inner region surface 2d, improving the sensitivity of the edge sensor S1 to lateral impacts, and also suppressing an increase in the thickness dimension H of the edge portion a of the cover 3, thereby improving the aesthetic appearance.

[0041] Furthermore, the frame 2 has a projection 2e that protrudes upward from the inner surface 2d toward the outer edge between the inner surface 2d and the mounting surface 2c, and the mounting surface 2c is inclined downward toward the outer edge at a larger angle than the surface of the cover 3 directly above it. As a result, the edge sensor S1 can be directed laterally relative to the upper surface of the cover 3, improving the sensitivity of the edge sensor S1 to lateral impacts, and also suppressing an increase in the thickness dimension H of the edge portion a of the cover 3, thereby improving the aesthetic appearance.

[0042] In particular, the protrusion 2e according to this embodiment consists of a stepped shape formed between the inner surface 2d and the mounting surface 2c. By forming a stepped shape on the frame 2, the range of the thin-walled portion of the cover 3 can be minimized while suppressing an increase in the thickness dimension H of the edge portion a of the cover 3, thereby improving the aesthetic appearance. However, instead of the stepped shape of the protrusion 2e, a slope shape consisting of a slope formed over a predetermined distance between the inner surface 2d and the mounting surface 2c may be used, as shown in Figure 11. In this case, by forming a slope shape on the frame 2, stress concentration on the frame 2 during impact can be reduced while suppressing an increase in the thickness dimension H of the edge portion a of the cover 3, thereby improving the aesthetic appearance.

[0043] Although this embodiment has been described above, the present invention is not limited thereto. For example, as shown in Figure 12, the frame 2 and cover 3 may have curved portions A1 and A2 that curve downward at predetermined locations. In this case, an inner region surface 2d is formed on the outside of the curved portions A1 and A2, and a protrusion 2e (2e') is formed between the inner region surface 2d and the mounting surface 2c. [Industrial applicability]

[0044] If the present invention is of the same nature, it can also be applied to products with different external shapes or those with added functions. [Explanation of symbols]
