For example, Patent Literature 1 below discloses an electronic cymbal in which the outer side of a hard resin disk-like frame that curves convexly upward is covered with a rubber cover.

JP 2002-062872 A

  On the other hand, in an acoustic cymbal (so-called live musical instrument) that makes a sound when a performer strikes a metal disk through a stick, a plurality of through holes are conventionally provided in the striking surface of the cymbal. There is an effect cymbal that can generate a different tone from the cymbal.

  However, in the electronic cymbal described in Patent Document 1, when a through hole is formed in the cymbal striking surface in order to reproduce the shape of the effect cymbal, this striking surface is composed of a frame and a cover. Due to the thick thickness, the difference from the thin acoustic cymbals appears remarkably, and there is a problem that the shape of the effect cymbals cannot be substantially reproduced.

  The present invention has been made to address the above-described problems, and an object thereof is to provide an electronic cymbal that can reproduce the shape of an effect cymbal without giving a thick impression on the thickness of the striking surface.

  In order to achieve the above object, the present invention is characterized by a cymbal pad having a hitting surface hit by a player, a hitting sensor for detecting hitting of the cymbal pad, and a hitting surface of the cymbal pad and the back side of the hitting surface. An electronic cymbal provided with a striking surface through-hole formed so as to penetrate between the back surface, and the striking surface through-hole has a hole size from the striking surface toward the back surface. Is formed on an inclined surface that expands.

  According to the characteristics of the present invention configured as described above, the electronic cymbal is an inclined surface in which the inner peripheral portion of the hole in the striking surface through hole formed in the cymbal pad increases in size from the striking surface to the back surface. Therefore, when the cymbal pad is viewed from the periphery, the inner periphery of the striking surface through hole is not conspicuous, and it is possible to suppress giving a thick impression to the striking surface thickness. It can be closer to the appearance.

  Another feature of the present invention is that, in the electronic cymbal, the striking surface through-hole is opened larger than the tip size of the tip of the stick that strikes the cymbal pad.

  According to another feature of the present invention configured as described above, the electronic cymbal can be struck even when the striking surface through hole is opened larger than the tip size of the tip of the stick that strikes the cymbal pad. It is difficult to visually recognize the inner peripheral portion of the surface through hole, a larger striking surface through hole can be formed, the number of striking surface through holes can be increased, and the appearance of various effect cymbals can be reproduced. .

  According to another feature of the present invention thus configured, the electronic cymbal is formed such that the inner peripheral portion of the striking surface through hole in the cymbal pad is thicker than the outer portion of the inner peripheral portion. Therefore, the rigidity of the inner peripheral portion of the striking surface through hole can be improved. This is because the inner peripheral portion of the hole in the hitting surface through-hole is formed on an inclined surface in which the size of the hole increases from the hitting surface toward the rear surface. This means that even if the thickness is increased, the inner peripheral portion of the striking surface through hole is not conspicuous, and it is possible to suppress giving a thick impression to the striking surface thickness, and it is easy to ensure rigidity.

It is in a larger inclination.

  According to another aspect of the invention configured as described above, the electronic cymbal includes a pad in which the cymbal pad is formed of a resilient material and a base body that supports the pad. Since the inner peripheral portion forming the surface through hole is more inclined with respect to the central axis of the hitting surface through hole than the inner peripheral portion forming the hitting surface through hole in the pad, the cymbal pad has a two-layer structure. Even in this case, it is possible to prevent the inner peripheral portion of the striking surface through-hole from appearing thick.

  Another feature of the present invention is that in the electronic cymbal, the cymbal pad is made of a resilient material to form the striking surface, and the pad is made of a material harder than the pad and the back surface of the pad. A pad that is supported from the side, and the pad is hooked on the inner peripheral portion that forms the striking surface through-hole in the base body, with the lower end portion of the inner peripheral portion that forms the striking surface through-hole projecting downward. There is in being.

  According to another aspect of the invention configured as described above, the electronic cymbal includes a pad in which the cymbal pad is formed of a resilient material and a base body that supports the pad, and a striking surface in the pad. Since the lower end portion of the inner peripheral portion that forms the through hole projects downward and is hooked on the inner peripheral portion that forms the striking surface through hole in the base body, the integrity at the inner peripheral portion of the striking surface through hole is And the separation of the pad and the base body due to changes over time such as the separation and deterioration of the pad and the base body when the pad is struck can be prevented, and the durability can be improved.

  Another feature of the present invention is that, in the electronic cymbal, the striking surface through-hole has a deep inner peripheral portion.

  According to another feature of the present invention configured as described above, the electronic cymbal is configured so that the inner peripheral portion of the striking surface through hole is dark, so that when the cymbal pad is viewed from the periphery, the striking surface through hole is formed. It is possible to suppress the inner peripheral portion of the material from being conspicuous and giving a thick impression to the thickness of the striking surface, and can be made closer to the appearance shape of the effect cymbal. The dark color constituting the inner peripheral portion of the striking surface through hole is a black color such as dark red, dark blue, dark brown or dark purple similar to black and black.

That is, the performer places the cymbal pad 101 on the support sleeve 122 in a state where the holding portion 104a of the cymbal pad mounting tool 104 is sandwiched between the two pressing tools 124a and 124b.

  Then, the performer tightens the tightening nut 123 by screwing the tightening nut 123 into the penetrating portion 121. As a result, the cymbal pad mounting tool 104 has the holding portion 104a pressed between the two pressing tools 124a and 124b in the axial direction of the penetrating portion 121, so that the inner peripheral portion of the holding portion 104a is on the penetrating portion 121 side. The support sleeve 122 is pressed along the circumferential direction to elastically deform the inner peripheral portion of the support sleeve 122 toward the penetrating portion 121.

  In this case, the performer can adjust the force with which the support sleeve 122 presses the penetrating portion 121 according to the tightening condition of the tightening nut 123. Thus, the performer can selectively set the degree of sliding resistance with which the cymbal pad 101 rotates and slides with respect to the stand 120 according to the tightening condition of the tightening nut 123, or the state in which rotation is impossible. . Then, the performer electrically connects the phone terminal 110 and the sound source via a signal cable (not shown) so that the electronic cymbal 100 can be played.

  The cymbal pad 101 may be supported by the stand 120 in a horizontal posture in which the radial direction of the cymbal pad 101 is orthogonal to the vertical direction, or the radial direction of the cymbal pad 101 is inclined with respect to the vertical direction. And may be supported by the stand 120 in a posture inclined toward the performer.

  Next, the performer plays the electronic cymbal 100. Specifically, the performer strikes the pad 106 constituting the upper surface of the cymbal pad 101 using a stick ST extending in a bar shape. More specifically, the performer strikes the cup portion 106a or the bow portion 106c of the pad 106. In such a performance process, when the cup part 106a or the bow part 106c in the pad 106 is hit in the cymbal pad 101, the vibration generated in the pad 106 is detected by the hit sensor 105a or the hit sensor 105b.

  Thereby, the tapping sensors 105a and 105b output a detection signal corresponding to the vibration propagated through the pad 106 to the sound source via the phone terminal 110. Thus, the sound source generates a musical sound signal representing a musical sound based on the detection signals input from the tapping sensors 105a and 105b and outputs the musical sound signal to an external speaker. As a result, the electronic cymbal 100 can output a musical sound according to the performance operation of the performer from the external speaker.

  Then, when the performer finishes playing the electronic cymbal 100, the player removes the electronic cymbal 100 from the stand 120 after disconnecting the electrical connection between the electronic cymbal 100 and the sound source. Thus, the performer can end the performance of the electronic cymbal 100.

  As can be understood from the above description of operation, according to the above embodiment, the electronic cymbal 100 has the inner periphery of each hole in the pad-side striking surface through-hole 107 and the base-body-side striking surface through-hole 103 formed in the cymbal pad 101. Since the portions 107a and 103a are formed on an inclined surface in which the size of the hole increases from the striking surface toward the back surface, when the cymbal pad 101 is viewed from the periphery, the pad-side striking surface through hole 107 and the base body-side striking surface are formed. The inner peripheral portions 107a, 103a of the surface through-hole 103 are not conspicuous, and it is possible to suppress giving a thick impression to the thickness of the striking surface, and the shape of the effect cymbal can be made closer to the appearance.

  Further, the implementation of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the object of the present invention.

  For example, in the above embodiment, the cymbal pad 101 is composed of the base body 102 and the pad 106. However, the cymbal pad 101 can be made of only one kind of material, for example, only a resin material or only a fiber reinforced plastic containing a resin material. In this case, the striking surface through-hole 108 is constituted by a through-hole made of one kind of material penetrating the plate surface of the cymbal pad 101 made of one kind of material.

  In the above embodiment, the striking surface through hole 108 is formed by the pad side striking surface through hole 107 having a diameter of 5 cm with respect to the cymbal pad 101 and the base body side striking surface through hole 103 communicating with the pad side striking surface through hole 107. Configured. However, as a matter of course, the size and number of the striking surface through holes 108 formed in the cymbal pad 101 are not limited to the above embodiment. In other words, one or more striking surface through holes 108 may be formed with respect to the cymbal pad 101. Further, when a plurality of striking surface through-holes 108 are formed on the cymbal pad 101, they need not necessarily be formed on the same circumferential direction, but can be formed on different circumferential directions.

  Also, the size of the striking surface through hole 108 may be 5 cm or less in diameter or 5 cm or more. In this case, the size of the striking surface through-hole 108 can be made closer to the appearance shape of the effect cymbal by forming it at a size larger than the size of the tip C (approximately 10 mm in diameter) at the tip of the stick ST. Further, when a plurality of striking surface through holes 108 are formed on the cymbal pad 101, they can be formed in different sizes. Further, the striking surface through-hole 108 is formed in a shape other than a circle (including an elliptical shape) in a plan view, for example, a polygon such as a triangle, a square, a pentagon, or a hexagon, or an irregular shape that is not a regular shape. You can also

  Further, in the above embodiment, the cymbal pad 101 is formed such that the inner peripheral portions 107a and 103a of the striking surface through hole 108 are thicker than the outer portions of the inner peripheral portions 107a and 103a. More specifically, the thickness of the inner peripheral portion 107a of the pad-side striking surface through hole 107 in the pad 106 and the inner peripheral portion 103a of the base body-side striking surface through-hole 103 in the base body 102 are set to be larger than the thicknesses of these peripheral portions. It was formed thick.

  Thereby, the electronic cymbal 100 can improve the rigidity of the inner peripheral portions 107 a and 103 a of the pad side striking surface through hole 107 and the base body side striking surface through hole 103. This is because the inner peripheral portions 107a, 103a of the holes in the pad side striking surface through hole 107 and the base body side striking surface through hole 103 are inclined surfaces in which the size of the hole increases from the striking surface toward the back surface. By being formed, the inner peripheral portions 107a and 103a are not conspicuous even if the respective inner peripheral portions 107a and 103a of the pad side hitting surface through hole 107 and the base body side hitting surface through hole 103 are thickened. This means that it is possible to suppress giving a thick impression to the thickness, and it is easy to ensure rigidity. However, the thickness of the inner peripheral portion of the pad-side striking surface through hole 107 in the pad 106 and the inner peripheral portion of the base body-side striking surface through-hole 103 in the base body 102 is the same as these peripheral thicknesses or more than these peripheral thicknesses. Of course, it can be formed thin.

  In the above embodiment, the inclination angle θ2 of the inner peripheral portion 107a of the pad side striking surface through hole 107 is set to 45 °, and the inclination angle θ1 of the inner peripheral portion 103a of the base body side striking surface through hole 103 is set to 60. Set to °. That is, the inclination angle θ1 of the inner peripheral portion 103a of the base body-side striking surface through hole 103 was set larger than the inclination angle θ2 of the inner peripheral portion 107a of the pad-side striking surface through hole 107. As a result, the electronic cymbal 100 shows that the inner peripheral portions 107a and 103a of the pad-side striking surface through-hole 107 and the base body-side striking surface through-hole 103 appear to be thick even when the cymbal pad 101 has a two-layer structure. Can be prevented.

  However, the inclination angle θ2 of the inner peripheral portion 107a of the pad side striking surface through hole 107 and the inclination angle θ1 of the inner peripheral portion 103a of the base body side striking surface through hole 103 are 0 with respect to the central axis CL of each striking surface through hole. It should just be set to exceed (parallel) and less than 90 °. Therefore, the inclination angle θ1 of the inner peripheral portion 103a of the base body-side striking surface through hole 103 can be set equal to or smaller than the inclination angle θ2 of the inner peripheral portion 107a of the pad-side striking surface through hole 107. Further, when the cymbal pad 101 is made of one kind of material as described above, the cymbal pad 101 can be configured to change the inclination angle to be larger or smaller in the middle of the inner peripheral portion of the striking surface through hole 108.

  In the above-described embodiment, the pad-side striking surface through-hole 107 has the protruding portion 107 b formed at the lower end portion of the inner peripheral portion 107 a and the receiving portion 103 b formed at the inner peripheral portion 103 a of the base body-side striking surface through-hole 103. It was configured to be caught on. As a result, the electronic cymbal 100 increases the integrity of the pad-side striking surface through-hole 107 and the base body-side striking surface through-hole 103 and improves the resistance to hitting the inner peripheral portion of the pad-side striking surface through-hole 107. Can do. However, the pad-side striking surface through-hole 107 may simply be placed on the inner peripheral portion 103 a without the inner peripheral portion 107 a being caught by the inner peripheral portion 103 a of the base body-side striking surface through-hole 103.

  Moreover, in the said embodiment, the hitting surface through-hole 108 formed the inner peripheral parts 107a and 103a in black. Thereby, the electronic cymbal 100 can suppress the inner peripheral portions 107a and 103a of the striking surface through hole 108 from being noticeable and giving a thick impression to the striking surface thickness when the cymbal pad 101 is viewed from the periphery. The shape of the effect cymbal can be made closer to the appearance. In this case, the same effect can be expected by forming the inner peripheral portions 107a and 103a in the striking surface through-hole 108 in dark colors including black. Here, the dark color is a black color such as dark red, dark blue, dark brown or dark purple similar to black and black. However, as for the hitting surface through-hole 108, it is natural that the inner peripheral portions 107a and 103a may be composed of a color other than these dark colors. The effect of making the inner peripheral portions 107a and 103a inconspicuous can be further improved by making the lower surface cover 111 the same color as the inner peripheral portions 107a and 103a. Of course, they may be formed in different colors.

  In the above embodiment, the recess 103 d is provided around the base body-side striking surface through hole 103 on the surface of the base body 102. As a result, the base body 102 has a good moldability by uniformizing the thickness around the base body-side striking face through-hole 103 when the resin material is injected into the mold and molded. Can be. However, the base body 102 can also be configured by omitting the recess 103 d around the base body-side striking surface through-hole 103.

  Moreover, in the said embodiment, the cymbal pad 101 comprised the cup part 106a and the bow part 106c. However, the cymbal pad 101 may be configured to have at least the bow portion 106c, and may be configured by only the bow portion 106c without the cup portion 106a.

  Moreover, in the said embodiment, the cymbal pad 101 was formed circularly by planar view. However, the cymbal pad 101 may be formed in a shape other than a circle in a plan view, for example, a fan shape in a plan view.

  In the above embodiment, the cymbal pad 101 includes the two tapping sensors 105a and 105b. However, the cymbal pad 101 only needs to include at least one tapping sensor that can detect tapping of the cymbal pad 101 by the player. Therefore, the cymbal pad 101 can also be configured by providing one or more tapping sensors that can detect each tapping of the cup portion 106a and the bow portion 106c in common. In this case, one or a plurality of tapping sensors that can detect each tapping of the cup portion 106 a and the bow portion 106 c in common can be provided on the back side of the base body 102.

  Further, in the above-described embodiment, the tapping sensors 105a and 105b are formed so that the piezo film is formed in a substantially annular C shape so that the cup portion 106a and the bow portion 106c have substantially the entire circumference in each circumferential direction (substantially the entire circumference). Lap). As a result, the tapping sensors 105a and 105b can accurately detect vibration regardless of the tapping position of the cup portion 106a and the bow portion 106c. In particular, in the bow portion 106c, since the hitting surface through hole 108 is formed, the uniform propagation of vibration may be hindered, but the hitting sensor 105b is provided on substantially the entire circumference of the edge portion 106d. Thus, hitting of the bow portion 106c can be detected with high accuracy.

  However, the tapping sensors 105a and 105b only need to be able to detect the vibration of the cymbal pad 101. An electrode other than a piezo film, for example, electrodes are arranged on both sides of a piezoelectric ceramic, and a metal plate is arranged on one of these electrodes. You may comprise a disk-shaped piezoelectric element by planar view. In this case, one or a plurality of tapping sensors 105a and 105b formed in a disk shape can be provided on the base body 102 along the circumferential direction. In this case, the tapping sensor 105b is disposed at a circumferential position different from the formation position of the striking surface through hole 108 on the plate surface of the bow portion 106c (in other words, on the same radial line as the striking surface through hole 108). The effect of the striking surface through hole 108 can be suppressed. Further, the tapping sensors 105a and 105b can be configured by a detector other than a piezo element or a piezo film, such as a pressure-sensitive sheet sensor or a sheet switch.
