It is a block diagram which shows the whole structure of the electronic percussion instrument provided with the cymbal pad. It is a figure which shows the flowchart of a main routine. It is a flowchart of processes, such as pronunciation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1A is an external view of an electronic drum set to which the cymbal pad according to the first embodiment of the present invention is applied. This electronic drum set is an electronic percussion instrument including a stand 10, a cymbal pad PD supported by the stand 10, and a musical sound generator 12 electrically connected to the cymbal pad PD.

  The cymbal pad PD is used as a ride cymbal as an example, but is not limited thereto, and may be applied to a cymbal such as a hi-hat or a crash. Alternatively, the cymbal pad PD can be used for practice. In that case, the cymbal pad PD can be struck and placed on a desk or the like without using the stand 10, and a mechanism for electronically generating sound can also be used. Not needed.

  1B and 1C are a top view and a side view of the cymbal pad PD, respectively. The cymbal pad PD is formed in a disk shape in plan view, and a support hole 17 is formed at the center in the radial direction. With the support column 17 penetrating the upper column 10a of the stand 10, an elastic material (not shown) is arranged so as to sandwich the cymbal pad PD from above and below, so that the cymbal pad PD is front, rear, left and right with respect to the upper column 10a. Is swingably supported.

  As shown in FIG. 1B, the cymbal pad PD is provided with an impact sensor 18 such as a piezo element. When the player 13 hits the cymbal pad PD with the stick 14, the hit sensor 18 detects the hit and a tone corresponding to the detection signal is generated from the tone generator 12. During the musical sound control, a signal from the sheet sensor sA (FIG. 2A) may be taken into consideration.

  The surface exposed on the upper side of the cymbal pad PD is a striking surface, and the striking region is a cup 40, a bow 30 and an edge 20 in order from the side closer to the support hole 17, all of which have an outer shape. It is circular. Since the cup 40 protrudes upward from the bow 30, it is distinguished by its appearance. The boundary between the bow 30 and the edge 20 is not distinguished in appearance, but a visual difference may be provided so that the boundary can be recognized.

  FIG. 2A is a schematic cross-sectional view showing the configuration of the cymbal pad PD. The cymbal pad PD has a two-layer structure in which the frame 21 and the surface member 29 are laminated in order from the back surface PDa side. The two-layer structure is applied to the entire cymbal pad PD. The exposed surface of the surface member 29 provides a striking surface that is struck by the stick 14. The impact sensor 18 is disposed on the lower surface of the frame 21.

  The frame 21 is made of hard plastic such as ABS (Acrylonitrile Butadiene Styrene) or PP (polypropylene), or a metal plate, and is a hard base portion having sufficient rigidity against impact. The surface member 29 provided so as to cover the frame 21 is made of a material softer than the material of the frame 21, and is made of, for example, a soft material such as rubber or foamed sponge. The surface member 29 has a function of quickly attenuating the vibration caused by the impact and relaxing the impact sound caused by the impact.

  The thickness of the frame 21 is thinner from the support hole 17 toward the outer side in the radial direction. In the frame 21, a portion corresponding to the cup 40 is a cup corresponding portion 21C, a portion corresponding to the bow 30 is a bow corresponding portion 21B, and a portion corresponding to the edge 20 is an edge corresponding portion 21A.

  Regarding the thickness of the frame 21, the minimum thickness in the cup corresponding portion 21C> the maximum thickness in the bow corresponding portion 21B, and the minimum thickness in the bow corresponding portion 21B> the maximum thickness in the edge corresponding portion 21A. As a result, the ease of bending at the time of impact (ease of deformation) becomes cup 40 <bow 30 <edge 20 and approximates an acoustic cymbal.

  FIGS. 2B and 2C are a cross-sectional view and a side view of the portion of the frame 21 corresponding to the edge 20. A sheet sensor sA is disposed on the outer peripheral edge portion 22 of the frame 21 (edge corresponding portion 21A). The sheet sensor sA is disposed over substantially the entire circumference of the outer peripheral edge portion 22 between the outer peripheral edge portion 22 and the surface member 29.

  An L-shaped flange portion 23 is formed integrally with the edge corresponding portion 21 </ b> A on the radially inner side of the frame 21 at the outer peripheral edge portion 22. The flange portion 23 includes a hanging rib 23a and an extending portion 23b that is formed to extend outward from the hanging rib 23a in the radial direction. On the other hand, the outer peripheral edge portion of the surface member 29 is formed with a folded portion 29a that is bent inward in the radial direction (FIG. 2A).

  When attaching the surface member 29 to the frame 21, the outer peripheral edge portion 22 is wrapped from the outer periphery by the folded portion 29a while covering the surface member 29 on the frame 21. As a result, the folded portion 29 a is engaged with the recess formed by the outer peripheral edge portion 22 and the flange portion 23. At this time, the upper surface of the frame 21 and the rear surface of the front surface member 29 may be fixed by adhesion or the like.

  By the way, the flange 23 may be formed continuously over the entire circumference of the edge corresponding portion 21A. However, in the present embodiment, in order to make the edge 20 more flexible than in the prior art, as shown in FIG. 2C, the flanges 23 are provided intermittently at intervals.

  According to the present embodiment, the edge corresponding portion 21A is thinner than the bow corresponding portion 21B in the frame 21, and thus is easily deformed by hitting. As a result, the edge 20 can be easily deformed, and a good hitting feel like an acoustic cymbal can be obtained. In this way, by making the thickness of the frame 21 different for each hitting region, it is possible to individually optimize the hit feeling between the bow 30 and the edge 20.

  2D and 2E are rear views of a frame 21 according to a modification. For example, as illustrated in FIGS. 2D and 2E, reinforcing ribs 25 protruding to the back side may be provided only on the bow corresponding portion 21 </ b> B in the frame 21. The reinforcing rib 25 has an effect of increasing the rigidity of the bow corresponding portion 21B and relatively easily bending the edge corresponding portion 21A. Therefore, the reinforcing ribs 25 may be provided in a plurality of radial ribs (FIG. 2 (d)) or concentric circles having different radii (FIG. 2 (e)). However, concentric circles are not essential.

  In addition, it is applicable also to the cup corresponding | compatible part 21C to make a hit feeling suitable separately. For example, in order to configure the bow corresponding portion 21B to bend more easily than the cup corresponding portion 21C, the cup corresponding portion 21C, the bow corresponding portion 21B, and the edge corresponding portion 21A have at least one of shape and material characteristics. What is necessary is just to set it as a different structure. For example, the slant angle of the striking surface may be cup corresponding part 21C> bow corresponding part 21B <edge corresponding part 21A.

(Second Embodiment)
FIG. 3A is a schematic cross-sectional view showing the configuration of the cymbal pad PD according to the second embodiment of the present invention.

  Similar to the first embodiment, the cymbal pad PD has a two-layer structure in which the frame 21 and the surface member 29 are laminated in order from the back surface PDa side. However, in the present embodiment, the frame 21 includes the cup corresponding part 21C, the bow corresponding part 21B, and the edge corresponding part 21A separately. Further, regarding the surface member 29, the surface cup corresponding portion 29C, the surface bow corresponding portion 29B, and the surface edge corresponding portion 29A corresponding to the cup 40, the bow 30 and the edge 20 are configured separately.

  The edge corresponding portion 21A and the surface edge corresponding portion 29A are assembled to form the edge constituting portion 26A. The bow corresponding portion 21B and the surface bow corresponding portion 29B are assembled to form a bow constituting portion 26B. The cup corresponding part 21C and the surface cup corresponding part 29C are assembled to form a cup constituting part 26C. Each assembly is performed by adhesion or the like. As for the edge corresponding portion 21A and the surface edge corresponding portion 29A, the outer peripheral edge portion 22 and the flange portion 23 and the folded portion 29a engage with each other as in the first embodiment.

  The materials of the frame 21 and the surface member 29 are the same as those in the first embodiment. The material characteristics of the edge corresponding part 21A, the bow corresponding part 21B, and the cup corresponding part 21C may be different. In this case, the hardness may be cup correspondence part 21C> bow correspondence part 21B> edge correspondence part 21A.

  The edge corresponding portion 21 </ b> A and the bow corresponding portion 21 </ b> B that are independent of each other are connected by the connecting portion 31, so that the bow forming portion 26 </ b> B and the edge forming portion 26 </ b> A are integrally connected. First, a connecting portion 31 is integrally formed on the edge corresponding portion 21 </ b> A so as to extend radially inward of the frame 21. The connecting portion 31 is attached to the bow corresponding portion 21 </ b> B with a screw 33 via the cushioning material 32. Fixing is not limited to screwing, and may be fitting, adhesion, or adhesion.

  Thereby, the connection part 31 becomes a hinge, and the edge constituent part 26A is configured to be easily bent like a cantilever with respect to the bow constituent part 26B. Therefore, as the material characteristic of the connecting portion 31, here, the material characteristic of the edge corresponding portion 21 </ b> A, it is preferable to set elasticity so as to be appropriately deformed when hitting the edge 20.

  FIG. 3B is a back view of a connecting portion between the edge corresponding portion 21A and the bow corresponding portion 21B. The connecting portion 31 may be formed over the entire circumference of the edge corresponding portion 21A, but in the present embodiment, the connecting portion 31 is provided intermittently in the circumferential direction as shown in FIG. Thereby, the connection part 31 becomes easy to bend.

  The connecting portion 31 is not limited to being formed integrally with the edge corresponding portion 21A, but may be formed integrally with the bow corresponding portion 21B. Alternatively, as shown in FIG. 3C, the connecting portion 31 is formed of a separate member from the edge corresponding portion 21 </ b> A and the bow corresponding portion 21 </ b> B, and is fixed to both via a buffer material 32. May be.

  Further, regarding the connection, the relationship between the bow component 26B and the edge component 26A has been described, but the manner of connection between the bow component 26B and the cup component 26C can be considered similarly.

  According to the present embodiment, since the edge constituting portion 26A, the bow constituting portion 26B and the connecting portion 31 are connected to each other, the independence of both is increased with respect to the displacement at the time of hitting, and when the edge 20 is hit, the edge constituting portion 26A is The amount of displacement can be increased. Thereby, the hit feeling can be clearly distinguished between when the bow 30 is hit and when the edge 20 is hit, and the hit feeling of the bow 30 and the edge 20 can be individually optimized. For example, the swing of the stick 14 can be performed in a natural state. Similarly, the hit feeling can be clearly made different between the cup 40 and the bow 30.

  By the way, in the present embodiment, the hit area vibrates particularly greatly, and it is difficult to transmit the vibration to other areas, so it is more suitable to detect the hit individually. Therefore, as shown in FIG. 3A, a sensor is provided for each hitting area.

  First, for the sheet sensor s, in addition to providing the same sheet sensor sA as in the first embodiment in the edge component 26A, sheet sensors sB and sC are provided in the bow component 26B and the cup component 26C, respectively. Further, as a vibration sensor corresponding to the impact sensor 18, an impact sensor p such as a piezo element that detects vibration or impact is provided for each component 26. That is, the hit sensors pA, pB, and pC are disposed on the back surfaces of the edge corresponding portion 21A, the bow corresponding portion 21B, and the cup corresponding portion 21C, respectively.

  Musical sound control may be performed based only on the outputs of the three batting sensors p, but in the present embodiment, the musical sound is controlled based on the outputs of the three batting sensors p and the outputs of the three sheet sensors s. To do.

  FIG. 4 is a block diagram showing an overall configuration of an electronic percussion instrument provided with a cymbal pad PD in the second embodiment.

  The electronic percussion instrument includes a ROM 52, a RAM 53, a timer 54, a storage device 55, a display device 56, a sound source 57, a sound system 58, and an interface 59 connected to the CPU 50 via the bus 51. Signals from the sensor group 60 and the panel operator 61 are input to the CPU 50 via the interface 59. A timer 54 is connected to the CPU 50, and a sound system 58 is connected to the sound source 57.

  The CPU 50 controls the entire musical instrument. The ROM 52 stores a control program executed by the CPU 50, various table data, and the like. The RAM 53 temporarily stores various input information, various flags, buffer data, calculation results, and the like. The timer 54 measures various times such as an interrupt time in the timer interrupt process. The storage device 55 stores various application programs including the control program, various music data, various data, and the like.

  The sound source 57 converts the tone generation signal input from the CPU 50, preset performance data, and the like into a musical tone signal. The sound system 58 applies various effects to the sound generation signal input from the sound source 57 and converts it into sound. The musical sound generator 12 (FIG. 1) corresponds to the constituent elements 52 to 58, and the sensor group 60 corresponds to the hit sensor p and the sheet sensor s.

  FIG. 5 is a flowchart of a main routine in the electronic percussion instrument. This process is started when the power is turned on and executed by the CPU 50.

  First, initialization is executed, that is, execution of a predetermined program is started, initial values are set in various registers, and initial setting is performed (step S101). Next, the operation of the panel operation element 61 is accepted, and an instruction such as device setting is executed (step S102). Next, a sound generation process or the like shown in FIG. 6 described later is executed (step S103), and the process returns to step S102.

  FIG. 6 is a flowchart of the sound generation process executed in step S103 of FIG.

  First, it is determined whether or not a sound is currently being generated (step S201), and if not sounding, the sound generation duration hkt is reset to zero (step S202). Increment (step S203). The pronunciation duration time hkt is a variable corresponding to the elapsed time from the start of pronunciation.

  After the process of step S202 or step S203, it is determined whether or not there is an output signal from the hit sensor pA of the edge corresponding portion 21A (step S204). If there is no output signal from the hit sensor pA as a result of the determination, it is determined whether there is an output signal from the hit sensor pB of the bow corresponding portion 21B (step S211). If there is no output signal from the hit sensor pB as a result of the determination, it is determined whether or not there is an output signal from the hit sensor pC of the cup corresponding portion 21C (step S213).

  As a result of the determination in step S204, if there is an output signal from the impact sensor pA, sound generation processing is executed in steps S205 to S210, and the process proceeds to step S211. If the result of determination in step S211 is that there is an output signal from the impact sensor pB, sound generation processing in step S212 is executed, and the flow proceeds to step S213. If the result of determination in step S213 is that there is an output signal from the impact sensor pC, sound generation processing in step S214 is executed, and the flow proceeds to step S215.

  Here, since the sound generation processing in steps S212 and S214 is the same as the processing in steps S205 to S210 except that the hit sensor p that is the output source of the signal to be processed is different, detailed description of the steps is omitted. Yes. Therefore, the sound generation process will be described in steps S205 to S210 related to the impact sensor pA as a representative.

  In step S205, it is determined whether or not “hkt> 10 or not sounding” is met. As a result of the determination, when “hkt> 10 or not sounding”, that is, even when sounding, a considerable time has elapsed since the start of sounding (hkt> 10) or when sounding is not sounding Advances to step S206. On the other hand, if it does not correspond to “hkt> 10 or not sounding”, that is, if it is in a state (hkt ≦ 10) shortly after the start of sounding, the process proceeds to step S208.

  When the process proceeds from step S205 to step S206, it is determined that a new hit has occurred, and therefore a new sound generation signal is generated based on the output of the hit sensor pA. Then, it is determined again whether or not the current sound is being generated (step S207). If the sound is being generated, the current sound generation is stopped (step S209), and the process proceeds to step S210. If it is not sounding, it will progress to step S210 as it is.

  On the other hand, when the process proceeds from step S205 to step S208, there is a musical sound that has just been started, so that the sounding for update is based on the sensor value at the start of sounding during the sounding and the output of the current hit sensor pA. Generate a signal. Thereafter, steps S209 and S210 are executed. At that time, sound generation processing is performed so that a continuous sound is generated by the sound generation signal and the sound generation signal generated for update.

  Here, the current pronunciation is generated based on the output of the impact sensor pB or the impact sensor pC by the processing of step S212 or step S214. Therefore, when the process of step S208 is executed, a sound generation signal corresponding to the outputs of at least two hit sensors p is generated.

  For example, as in the case where the vicinity of the boundary of the bow 30 with the edge 20 is strongly struck, a situation may occur in which the impact sensor pA also reacts immediately after the impact sensor pB reacts greatly (hkt ≦ 10). In such a case, the musical sound produced based on the output of the impact sensor pB is changed (updated) immediately after that based on the output of the impact sensor pA. At that time, the musical sound is preferably approximated to the hitting sound when the vicinity of the boundary between the bow 30 and the edge 20 is hit in the acoustic cymbal. This is because, in the acoustic cymbal, even when the ball is hit, the generated hitting sound is slightly different between the position far from the edge and the position close to the edge.

  In addition, steps S205 to S210, step S212, or step S214 may be executed in succession within a short time of hkt ≦ 10. Therefore, it is assumed that the sound generation started by the output of one hit sensor p is changed based on the output of another hit sensor p. However, since “hkt ≦ 10” is a very short time, substantially, except for this short time, a sound is generated by a sound signal synthesized based on the outputs of two or more impact sensors p. .

  As an example, waveform data is prepared for each of the three impact sensors p, and a synthesized signal obtained by synthesizing them according to the magnitude of the output signal is generated as a sound generation signal. Waveform data corresponding to the impact sensors pA, pB, and pC are waveform data wA, wB, and wC. Furthermore, when the hit sensor p reacts, the sheet sensor s corresponding to the hit position usually reacts, so the output of the sheet sensor s is also reflected in the composite signal.

  The composition ratio of the waveform data wA is “output signal of the impact sensor pA / added value of the output signals of the impact sensors pA, pB, and pC”. Similarly, the composition ratio of the waveform data wB and wC is “the output signal of the impact sensors pB and pC / the added value of the output signals of the impact sensors pA, pB and pC”.

  For example, when the ratio of the magnitudes of the output signals of the impact sensors pA, pB, and pC is 3: 2: 1, the synthesis ratio of the waveform data wA is 3/3 + 2 + 1 = 0.5, and the synthesis of the waveform data wB. The ratio is 2/3 + 2 + 1 = 0.33, and the synthesis ratio of the waveform data wC is 1/3 + 2 + 1 = 0.16. The output of the sheet sensor s is also added to these. As for the signal of the sheet sensor s, “1” is added for the output signal.

  Therefore, when the edge 20 is hit, the sheet sensor sA outputs a signal, and the sheet sensors sB and sC do not output a signal, the final composition ratio of the waveform data wA is 0.5 + 1, and the waveform The final synthesis ratio of the data wB and wC is 0.33 and 0.16. As a result, in step S210, a musical sound that is similar to the percussion sound that is generated when the edge of the acoustic cymbal is struck is generated.

  In step S215, various processes according to other inputs are executed.

  According to the processing of FIG. 6, it is possible to clarify the difference in musical sound depending on the striking position while preventing double sounding by one striking.

  In this process, the double noise is prevented by software. However, any method may be used as long as it is a method of masking in software by grasping the strength of the output of the impact sensor p and the difference in detection timing. Absent. For example, simply, sound may be generated according to the position of the impact sensor p that has output, and the second output of the impact sensor p within a predetermined time difference may be ignored.

  In the process of FIG. 6, sound generation control may be performed based on the output of the impact sensor p without providing the sheet sensor s. In that case, a striking position may be specified from the output magnitudes and detection timings of the three striking sensors p, and a musical sound corresponding to the identified striking position may be generated. For example, control is performed so that different musical tones are produced at the boundary position of the region and the position far from the boundary position. Or you may change an effect parameter simply with the output of the impact sensor p with respect to the musical sound generated by the output of the sheet sensor s.

  Note that providing the sensors s and p for each striking area and controlling the musical tone based on these outputs is also applicable to the configuration of the first embodiment.
