Embodiments of the present invention will be specifically described below with reference to the drawings.
As shown in FIGS. 1 to 6, the electronic cymbal according to the present embodiment includes a main body 1 that includes a pad section 2 and a frame section 3 and has a striking surface F that can be struck by a player; The device includes a piezoelectric element 4 (detection means) attached to the inner circumferential surface S of the frame portion 3 of the portion 1 and a cover member 8.

As shown in FIG. 1, the main body portion 1 is supported at a predetermined height by a support stand T extending vertically by stand leg portions Ta. The main body 1 includes a pad 2 having a hitting surface F that can be hit by a player, and a frame 3 that supports the back side of the pad 2. Further, a plurality of openings Ha are formed in the pad portion 2, and a plurality of openings Hb are formed in the frame portion 3, and these openings Ha and Hb communicate with each other to form a main body. 1 opening H is formed. Note that the reference numeral L in the figure indicates a tightening member for tightening and fixing the main body portion 1 to the support stand T.

The pad part 2 is made of a rubber material or soft resin (silicone rubber in this embodiment) that can be hit with a stick, and has an insertion hole in the center through which the support stand T can be inserted, as shown in FIGS. 10 and 11. It consists of a disk-shaped member in which 2a is formed. Further, the hitting surface F formed on the upper surface of the pad section 2 includes a cup section Fb formed by bulging at the center of the pad section 2, an edge section Fc formed at the peripheral edge of the pad section 2, and a cup section Fc formed at the periphery of the pad section 2. Fb and a bow portion Fa consisting of a region between the edge portion Fc.

The frame part 3 is made of hard resin or metal (ABS resin in this embodiment), and is a circular plate having an insertion hole 3a in the center thereof through which the support stand T can be inserted, as shown in FIGS. 12 and 13. It consists of a shaped member. Further, the pad portion 2 is attached to the surface of the frame portion 3 and integrated to form the main body portion 1, and a bulge is formed in the center portion corresponding to the cup portion Fb of the pad portion 2. A bulged portion 3b is formed.

Furthermore, a mounting surface Sa for mounting the piezoelectric element 4 is formed on the inner circumferential surface S of the bulging portion 3b in the frame portion 3. As shown in FIGS. 12 and 13, a plurality of such mounting surfaces Sa (four in this embodiment) are formed along the circumferential direction (circumferential direction) on the inner circumferential surface S of the frame section 3 of the main body section 1. A piezoelectric element 4 is attached to each attachment surface Sa.

As shown in FIGS. 14 and 15, the cover member 8 is made of an annular member having an opening 8a in the center through which a support stand T etc. can be inserted, and as shown in FIGS. It is attached so as to cover the inner circumferential surface S of the bulging portion 3b on the back side, as well as the substrate 5 (see FIGS. 3 to 6) on which a predetermined electric circuit is formed. This substrate 5 is electrically connected to each piezoelectric element 4 so that a detection signal from each piezoelectric element 4 is transmitted to the substrate 5. In the main body portion 1 according to the present embodiment, as shown in the enlarged view of FIG. 3, the edge of the cover member 8 and the frame portion 3 around the edge are formed to be smoothly continuous.

A piezoelectric element 4 serving as a vibration sensor (detection means) is attached via a buffer member D to a mounting surface Sa formed on the main body part 1 (frame part 3), and absorbs vibrations generated by hitting the hitting surface F. It consists of a sensor that can be converted into an electric signal, and as shown in FIGS. 8 and 9, an upper electrode 4a made of, for example, a silver conductor, a lower electrode 4b made of, for example, a brass plate, and interposed between the upper electrode 4a and the lower electrode 4b. The piezoelectric ceramic 4c is configured to include a piezoelectric ceramic 4c.

Further, the upper electrode 4a is connected to the wiring h1, and the lower electrode 4b is connected to the wiring h2. When the player hits the hitting surface F and the vibration is transmitted to the piezoelectric element 4, The entire structure is deflected, and a voltage corresponding to the amount of deflection is generated. When a 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 current flows through the wiring h1 and h2, so that it is output as an electrical signal through the board 5 and output cable 6. It happens.

However, although the piezoelectric element 4 generates a voltage and outputs an electric signal by bending in the direction b perpendicular to the mounting surface Sa, it has a structure that makes it difficult to bend in the direction a parallel to the mounting surface Sa. Therefore, vibration in the direction b perpendicular to the mounting surface Sa has higher output characteristics (output characteristics resulting in a higher voltage or higher current) than vibration in the direction a parallel to the mounting surface Sa. It looks like this.

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, and as shown in FIG. It is attached with an adhesive or the like in close contact with the surface Sa. The buffer member D is formed in a cylindrical shape, and as shown in FIG. (preferably about 67%), so that the deflection of the piezoelectric element 4 due to vibration can be ensured.

Furthermore, an edge sensor E is attached to the periphery on the front side of the frame portion 3, and is capable of detecting a strike against the edge portion Fc of the pad portion 2. Like 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 detection signals detected by the piezoelectric element 4 and the edge sensor E to the outside. Note that the output cable 6 has an output jack J formed at its tip, and is connectable to an external signal processing device (not shown).

When the performer hits the hitting surface F of the pad section 2 with a stick to vibrate the main body 1, the strength of the hitting is detected by the piezoelectric element 4, and an electrical signal corresponding to the strength is output. The signal will be output to an external signal processing device (not shown) via the cable 6. Note that a strike against the edge portion Fc is identified according to the on/off state of the edge sensor E, and if a strike is detected when the edge sensor E is off, it is determined that a strike has been made against the bow portion Fa or the cup portion Fb. The determination is made and a predetermined musical tone is output.

As shown in FIGS. 3 and 4, the shaft sleeve 7 is made of a cylindrical elastic member (in this embodiment, a rubber material) with an insertion hole formed in its center. The shaft sleeve 7 is attached to the support stand T in the insertion hole 3a of the frame portion 3, and suppresses vibrations generated by hitting the main body portion 1 from being transmitted to the support stand T. It is now possible to do so.

As shown in FIGS. 6 and 7, the mounting surface Sa is a surface inclined from a horizontal plane (a plane including the horizontal direction α) toward the center of the main body 1 in the vertical direction β, and the piezoelectric element 4 is attached to the main body 1. They are attached concentrically at equal intervals around the central axis C of No. 1 (see FIGS. 3 and 7). That is, since the inner peripheral surface S formed in the frame part 3 of the main body part 1 is formed in the shape of a truncated cone, a plurality of (main) In the embodiment, four mounting surfaces Sa are formed at equal intervals, and the piezoelectric elements 4 are mounted concentrically on each mounting surface Sa.

Furthermore, when the shape centered on the central axis C that includes a predetermined area (a predetermined area on the inner circumferential surface or the outer circumferential surface) of the main body part 1 is assumed to be a virtual conical shape, each mounting surface Sa is in the virtual conical shape. A plurality of mounting surfaces Sa (four in this embodiment) are formed concentrically around the central axis C on the side surface (a fan-shaped surface in the developed view, the same applies hereinafter), and each mounting surface Sa is attached to the frame section of the main body section 1. 3, the piezoelectric element 4 can be arranged three-dimensionally (three-dimensionally composed of the horizontal direction α and the vertical direction β). The piezoelectric element 4 can be sufficiently bent by vibration in either the horizontal direction α or the vertical direction β. Thereby, it is possible to output an electric signal favorably and uniformly against vibrations in both the horizontal direction α and the vertical direction β due to striking of the hitting surface F.

Furthermore, when the shape centered on the central axis C including a predetermined area of the main body part 1 is regarded as a virtual conical shape, each mounting surface Sa is concentrically formed around the central axis C on the side surface of the virtual conical shape. A plurality of (four in the present embodiment) mounting surfaces Sa according to the present embodiment are formed along the circumferential direction on the inner circumferential surface S of the frame portion 3 in the main body portion 1, and are formed along the circumferential direction. As shown in FIGS. 5 and 6, it consists of a plane (flat surface) corresponding to the attachment part of the piezoelectric element 4 (the buffer member D in this embodiment), and as shown in FIGS. They have the same shape (circular shape) and dimensions (diameter dimension). Note that the piezoelectric element 4 is not limited to having a circular outer shape, and may have an elliptical or rectangular outer shape. Shape.

Here, the electronic cymbal according to the present embodiment has an opening H formed at a predetermined position on the striking surface F, thereby giving it a design similar to an effect cymbal in an acoustic musical instrument. This opening H is formed by matching an opening Ha formed in the pad section 2 with an opening Hb formed in the frame section 3, and extends from the front surface of the main body section 1 (the striking surface F of the pad section 2) to the back surface. (the back surface of the frame portion 3), and is formed with a diameter increasing from the striking surface F side toward the back surface side.

Further, on the back side of the opening H (opening Hb formed in the frame part 3) of the electronic cymbal according to the present embodiment, as shown in FIG. It is equipped with a reinforcing part G. The reinforcing portion G is composed of a rib integrally formed on the periphery of the opening Hb in the frame portion 3, and as shown in FIG. 3 and FIGS. The opening edge on the outer edge side (outer diameter side) with respect to the main body part 1 is formed to protrude more.

Further, as shown in FIG. 3 and FIGS. 5 to 7, the reinforcing portion G according to the present embodiment is formed to protrude in an arc shape along the edge of the opening H (opening Hb of the frame portion 3). , the protrusion dimension becomes smaller continuously from the opening edge on the outer edge side with respect to the main body part 1 toward the opening edge on the center side with respect to the main body part 1 (so that the protrusion dimension gradually becomes smaller from the outer diameter side to the inner diameter side). It is formed.

According to this embodiment, the opening edge on the outer edge side of the main body part 1 protrudes more than the opening edge on the central side with respect to the main body part 1, and the reinforcing part G is formed, so that the opening H on the hitting surface F is formed. It is possible to reproduce the shape of the effect cymbal in which the opening H is formed, and it is also possible to make the striking surface F appear thinner while reinforcing the opening edge of the opening H. That is, in the main body part 1 supported at a predetermined height on the support stand T, the inner diameter side is easily visible through the opening H, and the outer diameter side is difficult to see. It is possible to secure the protrusion size on the center side (outer diameter side) while suppressing the protrusion size on the inner diameter side, and it is possible to effectively reinforce the opening edge while making the hitting surface F look thin.

Further, since the reinforcing portion G according to the present embodiment is formed to protrude in an arc shape along the edge of the opening H, the opening edge of the opening H is reinforced over the entire extension direction of the reinforcing portion G. The opening edge can be effectively reinforced. Furthermore, since the reinforcing part G according to the present embodiment has a continuously smaller protruding dimension from the opening edge on the outer edge side with respect to the main body part 1 toward the opening edge on the central side with respect to the main body part 1, the reinforcing part The G can be formed smoothly over the extending direction, and the design can be further improved while effectively reinforcing.

Furthermore, since the opening H according to the present embodiment is formed to penetrate through the pad part 2 and the frame part 3, and the reinforcing part G is formed to protrude from the back side of the frame part 3, the opening H The back side of the frame portion 3, which is difficult to see through the H, can be made to protrude and serve as a reinforcing portion, and the reinforcement can be reliably performed while maintaining the design. In addition, the frame portion 3 has a cover member 8 that covers the piezoelectric element (detection means) attached to the bottom surface, and the edge of the cover member 8 and the frame portion 3 around the edge thereof are formed smoothly and continuously. In addition, it is possible to prevent the cover member 8 from being seen through the opening H from the hitting surface F side, and to improve the design by eliminating the protrusion on the bottom side of the main body part 1.

The mounting surface Sa according to the present embodiment is a surface inclined from a horizontal plane (a plane including the horizontal direction α) toward the center of the main body 1 in the vertical direction β, and the piezoelectric element 4 is Since they are mounted concentrically at equal intervals around the central axis C, even if the striking surface F is struck from any of various directions, the piezoelectric element 4 can stably and reliably convert it into an electrical signal and output it. can.

In addition, if three or more piezoelectric elements 4 according to the present embodiment are attached concentrically at equal intervals around the central axis C of the main body 1, the piezoelectric elements 4 can stabilize the hitting against the hitting surface F. It is possible to convert it into an electric signal and output it uniformly in response to strikes in various directions. Furthermore, since the mounting surface Sa according to the present embodiment is provided along the circumferential direction on the outer circumferential surface or the inner circumferential surface of the main body portion 1, the piezoelectric element 4 absorbs vibrations caused by hitting the striking surface F from the striking surface F. Since the impact is received more evenly over the entire circumference, it is possible to suppress variations in the output of the electrical signal due to differences in the location of the impact.

Furthermore, the mounting surface Sa according to the present embodiment is formed along the circumferential direction on the outer peripheral surface or the inner peripheral surface of the main body part 1, and is a flat surface (flat surface) corresponding to the mounting part (buffer member D) of the piezoelectric element 4. Since the piezoelectric element 4 can be fixed to the mounting surface Sa more stably than when it is fixed to a curved surface. Note that the mounting surface Sa is not limited to a flat surface, but may be a curved surface forming the inner circumferential surface S (or outer circumferential surface).

In addition, since the mounting surface Sa according to the present embodiment has substantially the same shape and dimensions as the outer shape of the piezoelectric element 4, when the piezoelectric element 4 is attached, the piezoelectric element 4 is attached to the inner circumferential surface S of the main body 1. The mounting position of the piezoelectric element 4 can be accurately grasped, and the positioning accuracy of the piezoelectric element 4 can be improved. That is, by attaching the piezoelectric element 4 in correspondence with the attachment surface Sa, the positioning of the piezoelectric element 4 is performed naturally, and the positioning accuracy can be improved.

Furthermore, the piezoelectric element 4 according to this embodiment is attached with the buffer member D and is attached to the mounting surface Sa with the buffer member D in contact with the piezoelectric element 4, so that the piezoelectric element 4 is prevented from being damaged by vibrations caused by hitting. can be avoided. The material and shape of the buffer member D are not limited as long as it has cushioning properties and can be attached to the bottom surface of the piezoelectric element 4.

Although the present embodiment has been described above, the present invention is not limited thereto. For example, as shown in FIG. The reinforcing portion G may not be formed protruding from the opening edge on the center side (inner diameter side) with respect to the main body portion 1. In this case, the opening edge can be reinforced without forming the reinforcing part G visible from the opening H.

Further, as shown in FIG. 17, the reinforcing portion G is formed only at the opening edge on the outer edge side (outer diameter side) with respect to the main body portion 1, and the reinforcing portion G is formed on the opening edge on the central side (inner diameter side) with respect to the main body portion 1. G may not be formed to protrude, and the reinforcing portion G may be formed along the circumferential direction of the main body portion 1 (frame portion 3). Further, the reinforcing portion G is not limited to having an inverted triangular cross-sectional shape, and may be a rib having another cross-sectional shape such as a rectangular or U-shape.

Furthermore, the buffer member D is not limited to a cylindrical shape as in the above embodiment, but may be an annular shape as shown in FIGS. 21 and 22. The back surface Db of such an annular buffer member D is attached to the bottom surface (lower electrode 4b) of the piezoelectric element 4 with an adhesive or the like, and the front surface Da is attached to the mounting surface Sa with an adhesive or the like. It is considered a thing. The annular buffer member D has an outer diameter t1 that 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 hitting, thereby ensuring the voltage of the output electric signal. It is possible to accelerate the attenuation and prevent mispronunciation.

However, in the annular buffer member D, it is preferable that the inner diameter t2 of the inner hollow part is 60 to 80% of the outer diameter t1, and the inner diameter t2 of the inner hollow part is 60% to 80% of the outer diameter t1. Most preferably it is 70%. In addition, in the annular buffer member D according to another embodiment, the surface Da that comes into close contact with the mounting surface Sa is a flat surface, but a slit is formed on a part or the entire circumference of the surface Da. Alternatively, the ratio between the inner diameter t2 and the outer diameter t1 may be another ratio.

In this embodiment, the main body part 1 is composed of the pad part 2 and the frame part 3, and the mounting surface Sa is formed on the inner circumferential surface S of the frame part 3. A mounting surface may be formed on the inner peripheral surface. Furthermore, in the present embodiment, the piezoelectric element 4 is capable of detecting a strike on the striking surface F and outputting an electrical signal, but other types of vibration sensors may be used to detect vibrations caused by the strike. Good too.

If the electronic cymbal has a reinforced part formed by protruding the opening edge on the outer edge of the main body more than the opening edge on the central side of the main body, the cymbal has a different external shape or has other functions added. It can also be applied to things.
