Description

Technical Field

[0001] The invention relates to an electronic cymbal capable of detecting the striking of a striking surface and outputting an electrical signal. Background Art

[0002] An electronic cymbal as a conventional electronic percussion instrument, such as disclosed in Patent Document 1, includes an electronic cymbal body composed of a pad having a striking surface that can be struck by a player and a frame portion that supports the back side of the pad, a vibration sensor that can detect the striking of the striking surface of the pad, 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 body with a stick, the vibration sensor can detect it and output it to the outside, so that it can be played like an acoustic cymbal.

[0003] In addition, as a conventional electronic cymbal, it has been proposed to form an opening at a predetermined position on a striking surface so as to have a design like an effect cymbal in an acoustic musical instrument. In this electronic cymbal, an opening is formed at a predetermined position on the striking surface, and the opening is formed in such a manner that the aperture expands from one side of the striking surface to the back side, so as to weaken the impression that the thickness of the striking surface is thick. Therefore, the shape of an effect cymbal with an opening formed on the striking surface can be reproduced, while making the striking surface look thinner, thereby improving its design.

[0008] Technical issues

[0009] However, in the above-mentioned prior art, the opening is formed in a manner in which the aperture expands from one side of the striking surface to the back side. Although this can make the striking surface thinner while reproducing the shape of the effect cymbal, it is necessary to form a reinforcing portion such as ribs protruding integrally at the edge of the opening for reinforcement, so that the ribs are exposed from the opening, thereby hindering the impression that the striking surface is thinner.

[0010] The present invention is proposed in view of the above situation, 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 can make the striking surface look thinner while reinforcing the opening edge of the opening.

[0011] Technical means

[0012] The present invention provides an electronic cymbal, which includes: a main body, having a striking surface that can be struck by a performer, and an opening portion formed at a predetermined position on the striking surface; a reinforcement portion, an opening edge of the opening portion protrudingly formed on the back side of the main body; a detection element installed on the main body, capable of detecting the strike on the striking surface and outputting an electrical signal; wherein the reinforcement portion is formed in a manner that the opening edge relative to the outer edge side of the main body is more protruding than the opening edge relative to the center side of the main body.

[0013] Optionally, in the electronic cymbal described in the present invention, the reinforcement portion is formed to protrude in an arc shape along the edge of the opening portion.

[0014] Optionally, in the electronic cymbal described in the present invention, the reinforcement portion is only formed on the opening edge on the outer edge side relative to the main body portion, and the reinforcement portion is not protruded to form the opening edge on the center side relative to the main body portion.

[0015] Optionally, in the electronic cymbal described in the present invention, the reinforcement part is formed in a manner in which the protruding size gradually decreases from the opening edge on the outer edge side relative to the main body part to the opening edge on the center side relative to the main body part.

[0016] Optionally, in the electronic cymbal described in the present invention, the main body portion is composed of a striking pad forming a striking surface and a frame portion supporting the back side of the striking pad, the opening portion is formed by passing through the striking pad and the frame portion, and the reinforcement portion is formed by protruding from the back side of the frame portion.

[0017] Optionally, in the electronic cymbal described in the present invention, a cover member covering the detection element is installed on the bottom surface of the frame portion, and the edge of the cover member and the frame portion around it are smoothly and continuously formed.

[0018] Technical Effects

[0019] The electronic cymbal provided by the present invention forms a reinforcement portion in a manner that the opening edge on the outer edge side relative to the main body is more protruding than the opening edge on the center side relative to the main body. Therefore, it is possible to reproduce the shape of an effect cymbal with an opening formed on the striking surface, and can make the striking surface look thinner while reinforcing the opening edge of the opening.

[0020] In the electronic cymbal provided by the present invention, since the reinforcement part is formed in an arc shape protruding along the edge of the opening part, the opening edge of the opening part can be reinforced in the entire extension direction of the reinforcement part, thereby effectively reinforcing the opening edge.

[0021] The electronic cymbal provided by the present invention has a reinforcement portion formed only on the opening edge on the outer edge side relative to the main body, and no reinforcement portion is protruded from the opening edge on the center side relative to the main body. Therefore, the opening edge can be reinforced without forming a reinforcement portion visible from the opening.

[0022] The electronic cymbal provided by the present invention is formed in a manner where the protruding size gradually decreases from the opening edge on the outer edge side relative to the main body to the opening edge on the center side relative to the main body. Therefore, the reinforcement part can be smoothly formed in the entire extension direction, thereby improving its design while providing effective reinforcement.

[0023] The electronic cymbal provided by the present invention has an opening portion formed by penetrating the striking pad and the frame portion, and a reinforcement portion protruding from the back side of the frame portion. Therefore, the reinforcement portion can be formed on the back side of the frame portion that is difficult to see through the opening portion, thereby improving its design while providing effective reinforcement.

[0024] The electronic cymbal provided by the present invention has a cover member covering the detection element installed on the bottom surface of the frame part, and the edge of the cover member and the frame part around it are smoothly and continuously formed. Therefore, it is possible to avoid seeing the cover member from the striking surface through the opening part, and at the same time, remove the protrusion on one side of the bottom surface of the main body to improve its design.

[0072] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0073] The electronic cymbal of this embodiment is as follows Figures 1 to 6 As shown, the electronic cymbal includes a main body 1 consisting of a striking pad 2 and a frame 3, which has a striking surface F that can be struck by a performer, a piezoelectric element 4 (detection element) installed on the inner peripheral surface S of the frame 3 in the main body 1, and a cover member 8.

[0074] The main body 1 is as follows Figure 1As shown in the figure, the support frame T is supported at a predetermined height by the support legs Ta extending in the vertical direction. The main body 1 is composed of a pad 2 having a striking surface F that can be struck by a player and a frame 3 supporting the back side of the pad 2. In addition, a plurality of openings Ha are formed in the pad 2, and a plurality of openings Hb are formed in the frame 3. These openings Ha and the openings Hb are connected and constitute the openings H of the main body 1. In addition, the reference numeral L in the figure indicates a tightening member for tightening and fixing the main body 1 relative to the support frame T.

[0075] The striking pad 2 is made of a rubber material or soft resin (silicon rubber in this embodiment) that can be struck with a stick. Fig.10 and Fig.11 As shown in FIG. 1 , the pad 2 is composed of a disk-shaped member having an insertion hole 2a formed at the center thereof into which the support frame T can be inserted. In addition, the striking surface F formed on the upper surface of the striking pad 2 is composed of a cup-shaped portion Fb formed by a protrusion at the center of the striking pad 2, an edge portion Fc formed at the edge of the striking pad 2, and an arcuate portion Fa formed by a region between the cup-shaped portion Fb and the edge portion Fc.

[0076] The frame portion 3 is made of hard resin or metal (ABS resin in this embodiment). Fig.12 and Fig.13 As shown, it is composed of a disk-shaped member having an insertion hole 3a formed at the center thereof into which a support frame T can be inserted. In addition, the body 1 is formed by mounting and integrating the striking pad 2 on the surface of the frame 3, and a protrusion 3b corresponding to the cup-shaped portion Fb of the striking pad 2 is formed at the center thereof.

[0077] In addition, a mounting surface Sa for connecting the piezoelectric element 4 is formed on the inner peripheral surface S of the protrusion 3b in the frame portion 3. The mounting surface Sa is as shown in FIG. Fig.12 and Fig.13 As shown, a plurality of (four in this embodiment) piezoelectric elements 4 are formed along the circumferential direction at the inner circumferential surface S of the frame portion 3 in the body portion 1, and a piezoelectric element 4 is mounted on each mounting surface Sa.

[0078] The cover member 8 is as follows Fig.14 and Fig.15 As shown, it is made of a ring-shaped member having an opening 8a in the center into which a support frame T etc. can be inserted, and as shown in FIG. Figure 2 and Figure 3 As shown, on the back side of the frame portion 3, the inner peripheral surface S of the protrusion 3b is covered and the substrate 5 on which a predetermined circuit is formed is covered (see Figures 3 to 6 ) is installed. The substrate 5 is electrically connected to each piezoelectric element 4 and transmits the detection signal of each piezoelectric element 4 to the substrate 5. In addition, in the main body 1 of this embodiment, Figure 3 As shown in the enlarged view of FIG. 8 , the edge of the cover member 8 and the frame portion 3 around it are formed smoothly and continuously.

[0079] The piezoelectric element 4 as a vibration sensor (detection element) is mounted on the mounting surface Sa formed on the main body 1 (frame 3) through the buffer member D, and is composed of a sensor capable of converting the vibration generated by striking the striking surface F into an electrical signal, such as Figure 8 and Fig. 9 As shown, the structure includes an upper electrode 4a made of a silver conductor, for example, a lower electrode 4b made of a brass plate, for example, and a piezoelectric ceramic 4c interposed between the upper electrode 4a and the lower electrode 4b.

[0080] Furthermore, the wiring h1 is connected to the upper electrode 4a, and the wiring h2 is connected to the lower electrode 4b, and when the player strikes the striking surface F and the vibration is transmitted to the piezoelectric element 4, the whole is vibrated and bent, and a voltage corresponding to the bending amount is generated. When the voltage is generated in this way, the upper electrode 4a acts as a positive electrode and the lower electrode 4b acts as a negative electrode, and the current flows through the wiring h1 and h2, and the electrical signal is output through the substrate 5 and the output cable.

[0081] However, although the piezoelectric element 4 generates voltage and outputs an electrical signal by bending in a direction b orthogonal to the mounting surface Sa, its structure is difficult to bend in a direction a parallel to the mounting surface Sa, and therefore has an output characteristic in which the vibration in the direction b perpendicular to the mounting surface Sa is higher than the vibration in the direction a parallel to the mounting surface Sa (resulting in an output characteristic of higher voltage or higher current).

[0082] Furthermore, the piezoelectric element 4 according to the present embodiment has a cushioning member D having a cushioning property made of urethane foam or the like mounted on its bottom surface, such as Fig. 9 As shown, the surface of the buffer member D is adhered to the mounting surface Sa with an adhesive or the like. In addition, the buffer member D is formed into a cylindrical shape, such as Fig. 9 As shown, it has an outer shape that is smaller than the outer diameter of the piezoelectric element 4 (preferably about 67% of the diameter of the piezoelectric element as the vibration node of the piezoelectric element 4) to ensure that the piezoelectric element 4 can bend with vibration.

[0083] In addition, an edge sensor E is installed on the outer peripheral edge of the surface side of the frame portion 3, and can detect the impact on the edge portion Fc of the striking pad 2. The edge sensor E is electrically connected to the substrate 5 through wiring like the piezoelectric element 4, and transmits the detection signal to the substrate 5. The output cable 6 is connected to the piezoelectric element 4 (vibration sensor) and the edge sensor E through the substrate 5, so that the detection signal detected by the piezoelectric element 4 and the edge sensor E can be output to the outside. The output cable 6 forms an output jack J at its front end, and can be connected to an external signal processing device (not shown).

[0084] Then, when the player strikes the striking surface F of the striking pad 2 with a stick and vibrates the main body 1, the piezoelectric element 4 detects the intensity of the strike and outputs an electrical signal corresponding to the intensity to an external signal processing device (not shown) through the output cable 6. In addition, the strike on the edge portion Fc is recognized based on the on / off state of the edge sensor E, and when the strike is detected when the edge sensor E is off, it is determined that the bow portion Fa or the cup portion Fb has been struck and a predetermined musical sound is output.

[0085] The shaft sleeve 7 is as follows Figure 3 and Figure 4 As shown, it is composed of a cylindrical elastic member (rubber material in this embodiment) with an insertion hole in the center. The shaft sleeve 7 is located between the support frame T in the insertion hole 3a of the frame part 3, which can suppress the vibration generated by knocking the main body 1 from being transmitted to the support frame T.

[0086] The mounting surface Sa is as follows Figure 6 and Figure 7 As shown, the piezoelectric element 4 is composed of a surface inclined from a horizontal plane (including a surface in the horizontal direction α) toward a vertical direction β at the center of the main body 1, and the piezoelectric element 4 is around the central axis C of the main body 1 (refer to Figure 3 and Figure 7 ) are installed in a manner of concentric circles with equal intervals. That is, since the inner circumferential surface S formed in the frame portion 3 of the main body portion 1 is formed in a truncated cone shape, a plurality of (four in this embodiment) mounting surfaces Sa are formed in the inner circumferential surface S at equal intervals along the circumferential direction centered on the central axis C, and the piezoelectric element 4 is installed in a concentric circle at each mounting surface Sa.

[0087] Furthermore, when the shape around the central axis C including the predetermined area of ​​the main body 1 (the predetermined area on the inner circumference or the outer circumference) is regarded as a virtual cone shape, on the side of the virtual cone shape (the fan-shaped surface in the unfolded view, the same below), a plurality of mounting surfaces Sa form concentric circles around the central axis C, and each mounting surface Sa is composed of a surface inclined at a predetermined angle from the horizontal plane to the vertical direction β toward the center of the frame portion 3 of the main body 1, so that the piezoelectric element 4 can be arranged in a three-dimensional manner (three-dimensional consisting of the horizontal direction α and the vertical direction β), and the piezoelectric element 4 can be fully bent under vibration in the horizontal direction α and the vertical direction β. Therefore, for the vibration in both the horizontal direction α and the vertical direction β due to the striking of the striking surface F, the electrical signal can be output well and evenly.

[0088] Furthermore, when the shape around the central axis C including the predetermined area of ​​the main body 1 is regarded as a virtual cone shape, on the side of the virtual cone shape, a plurality of mounting surfaces Sa are formed concentrically around the central axis C (four in the present embodiment), and the mounting surface Sa according to the present embodiment is formed along the circumferential direction in the inner circumferential surface S of the frame portion 3 in the main body 1, as shown in FIG. Figure 6 and Figure 7 As shown in FIG. 1 , it is composed of a plane (flat surface) corresponding to the mounting portion of the piezoelectric element 4 (the buffer member D in this embodiment), as shown in FIG. Figure 5 and Figure 6 As shown, the shape (circular) and size (diameter size) are formed to be substantially the same as the outer shape of the piezoelectric element 4. In addition, the outer shape of the piezoelectric element 4 is not limited to a circular shape, but may also have an elliptical or rectangular shape. Even in this case, the shape of the mounting surface Sa is substantially the same as the outer shape of the piezoelectric element 4.

[0089] Here, the electronic cymbal of this embodiment can have a design similar to that of an effect cymbal in an acoustic instrument by forming an opening H at a predetermined position on the striking surface F. The opening H is formed by overlapping the opening Ha formed in the striking pad 2 and the opening Hb formed in the frame 3, and is formed by penetrating from the surface of the body 1 (the striking surface F of the striking pad 2) to the back side (the back side of the frame 3), and expanding the aperture from the striking surface F side to the back side.

[0090] In addition, the back side of the opening H (opening Hb formed in the frame 3) of the electronic cymbal of this embodiment is as follows: Figure 3 As shown in FIG. 1 , a reinforcement portion G is provided which is formed by protruding from the opening edge of the opening portion H. The reinforcement portion G is composed of a rib integrally formed on the periphery of the opening portion Hb of the frame portion 3, as shown in FIG. Figure 3 and Figures 5 to 7 As shown, the opening edge on the outer edge side (outer diameter side) of the main body 1 is formed to protrude more than the opening edge on the center side (inner diameter side) of the main body 1 .

[0091] In addition, the reinforcement portion G of this embodiment is as follows Figure 3 and Figures 5 to 7 As shown, the protrusion along the edge of the opening portion H (the opening portion Hb of the frame portion 3) is formed into an arc shape, and is formed in a manner such that the protrusion size gradually decreases from the opening edge on the outer edge side relative to the main body portion 1 to the opening edge on the center side relative to the main body portion 1 (such as gradually decreasing the protrusion size from the outer diameter side to the inner diameter side).

[0092] According to the present embodiment, since the reinforcement part G is formed in such a manner that the opening edge on the outer edge side relative to the main body 1 protrudes more than the opening edge on the center side relative to the main body 1, the shape of the effect cymbal having the opening part H formed on the striking surface F can be reproduced, and the striking surface F can be made to look thinner while reinforcing the opening edge of the opening part H. That is, since the main body 1 supported at a predetermined height by the support frame T can be easily seen on the inner diameter side through the opening part H, and the outer shape side can be hardly seen, the protruding size on the outer edge side (inner diameter side) of the reinforcement part G can be suppressed, while the protruding size on the center side (outer diameter side) can be ensured, and the opening edge can be effectively reinforced while making the striking surface F look thinner.

[0093] In addition, since the reinforcement portion G of the present embodiment protrudes along the edge of the opening portion H to form an arc shape, the opening edge of the opening portion H can be reinforced in the entire extension direction of the reinforcement portion G, and the opening edge can be effectively reinforced. In addition, since the reinforcement portion G is formed in a manner in which the protruding size gradually decreases from the opening edge on the outer edge side relative to the main body portion 1 to the opening edge on the center side relative to the main body portion 1, the reinforcement portion G can be smoothly formed in the entire extension direction, so that the design thereof can be improved while effectively reinforcing.

[0094] Furthermore, since the opening H is formed by penetrating the striking pad 2 and the frame 3, and the reinforcement G is formed by protruding from the back side of the frame 3, the reinforcement can be formed on the back side of the frame 3 which is difficult to see through the opening H, so that the design is improved while effectively reinforcing. Furthermore, since the cover member 8 covering the piezoelectric element (detection element) is mounted on the bottom surface of the frame 3, and the edge of the cover member 8 and the frame 3 around it are formed smoothly and continuously, it is possible to avoid seeing the cover member 8 from the striking surface F through the opening H, and at the same time, the protrusion on the bottom side of the main body 1 is removed to improve its design.

[0095] In addition, since the mounting surface Sa of the present embodiment is composed of a surface inclined from a horizontal plane (including the surface in the horizontal direction α) to a vertical direction β of the center of the main body 1, and the piezoelectric element 4 is installed in a concentric circle at equal intervals around the central axis C of the main body 1, even if it is struck on the striking surface F from any different direction, it can be stably and reliably converted into an electrical signal by the piezoelectric element 4 and output.

[0096] Furthermore, if three or more piezoelectric elements 4 according to the present embodiment are installed in a concentric circle at equal intervals around the central axis C of the main body 1, the knocking on the striking surface F can be stably converted into an electrical signal by the piezoelectric element 4, and the knocking in various directions can be output uniformly. In addition, since the mounting surface Sa of the present embodiment is arranged along the circumferential direction on the outer circumference or inner circumference of the main body 1, the piezoelectric element 4 can receive the vibration of the knocking striking surface F uniformly over the entire striking surface F, thereby suppressing the change in the electrical signal output caused by the difference in the knocking position.

[0097] In addition, since the mounting surface Sa of the present embodiment is formed along the circumferential direction on the outer circumferential surface or the inner circumferential surface of the main body 1 and is composed of a plane (flat surface) corresponding to the mounting portion (buffer member D) of the piezoelectric element 4, the piezoelectric element 4 can be stably fixed to the mounting surface Sa compared to the case of fixing to a curved surface. In addition, the mounting surface Sa is not limited to a flat surface, but may also be a curved surface forming the inner circumferential surface S (or outer circumferential surface).

[0098] In addition, since the mounting surface Sa of the present embodiment is substantially the same as the external shape and size of the piezoelectric element 4, the mounting position of the piezoelectric element 4 relative to the inner peripheral surface S of the main body 1 can be accurately grasped during the mounting work of the piezoelectric element 4, thereby improving the positioning accuracy of the piezoelectric element 4. In other words, by mounting the piezoelectric element 4 corresponding to the mounting surface Sa, the piezoelectric element 4 can be naturally positioned, thereby improving the positioning accuracy.

[0099] In addition, since the piezoelectric element 4 of this embodiment is mounted on the mounting surface Sa by being provided with and in contact with the buffer member D, it is possible to prevent the piezoelectric element 4 from being damaged by vibrations caused by knocking. The buffer member D can be mounted on the bottom surface of the piezoelectric element 4 while having a buffering property, and its material and shape are not limited.

[0100] Although the present embodiment has been described above, the present invention is not limited thereto. Fig.16 As shown, the reinforcement portion G may be formed only on the opening edge on the outer edge side (outer diameter side) relative to the main body 1, and the reinforcement portion G may not be formed protrudingly on the opening edge on the center side (inner diameter side) relative to the main body 1. In this case, the opening edge can be reinforced without forming the reinforcement portion G visible from the opening H.

[0101] In addition, if Fig.17As shown, the reinforcing portion G may be formed only on the opening edge portion on the outer edge side (outer diameter side) relative to the main body 1, and the reinforcing portion G may not be formed protrudingly on the opening edge portion on the center side (inner diameter side) relative to the main body 1, and the reinforcing portion G may be formed along the outer circumferential direction of the main body 1 (frame portion 3). In addition, the reinforcing portion G may also be a rib portion made of other cross-sectional shapes such as a rectangle or a U-shape, and is not limited to a cross-sectional shape having an inverted triangle.

[0102] In addition, the buffer member D is not limited to the cylindrical shape as in the above-mentioned embodiment, but can also be annular as shown in Figures 21 and 22. In the above-mentioned annular buffer member D, the back side Db is attached to the bottom surface (lower electrode 4b) of the piezoelectric element 4 with an adhesive or the like, and the surface Da is attached to the mounting surface Sa with an adhesive or the like. In addition, the annular buffer member D has an annular shape with an outer diameter dimension t1 substantially equal to the outer diameter dimension of the piezoelectric element 4. Therefore, while suppressing the excessive free vibration of the piezoelectric element 4 itself caused by knocking, the piezoelectric element 4 can well follow the bending of the main body 1, thereby ensuring the voltage of the output electrical signal and accelerating the attenuation to prevent pronunciation errors.

[0103] However, in the annular buffer member D, the inner diameter t2 of the inner hollow portion is preferably 60 to 80% of the outer diameter t1, and the inner diameter t2 of the inner hollow portion is most preferably 70% of the outer diameter t1. In addition, in the annular buffer member D according to another embodiment, the surface Da in close contact with the mounting surface Sa is a flat surface, but a slit may be formed on a part or the entirety of the surface Da, or the ratio of the inner diameter t2 to the outer diameter t1 may be set to another ratio.

[0104] In addition, in the present embodiment, the main body 1 is composed of the striking pad 2 and the frame 3, and the mounting surface Sa is formed on the inner peripheral surface S of the frame 3, but the mounting surface may be formed on the inner peripheral surface of a single main body 1. In addition, in the present embodiment, the piezoelectric element 4 is used to detect the knock on the striking surface F and output an electrical signal, but other forms of vibration sensors may be used to detect the vibration caused by the knock.

[0105] Industrial Applicability As long as the electronic cymbal has a reinforcement portion formed in a manner that the opening edge on the outer edge side of the main body is more protruding than the opening edge on the center side of the main body, it can also be applied to musical instruments with different appearance shapes or additional functions.
