Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a kind of vertical view of electronics drum, electronics drum 1 can be broken down into small cymbals heart part 30, comprise opening shape center 1a (as shown in Figure 2) and (projection) dome structure part and small cymbals limit part 32, and the small cymbals face portion 31 between small cymbals heart part 30 and small cymbals limit part 32.
The upper surface of electronics drum 1 is coated with coverture 2.Small cymbals heart part 30 is made up of the core of dome structure center and coverture 2.As this obducent material, many good characteristics of existing rubber have the large-duty characteristics as plastic products again.
What Fig. 2 showed is the upper surface portion that coverture 2 covers the electronics drum.The upper surface of the coverture 2 of overlay electronic drum 1 upper surface adopts concavo-convex concentric ring to constitute.By this processing, obtain the irregular information of knocking.That is to say that the width of the concentric ring of protrusion will be wider than the width of depression concentric ring, with being intended to increase friction factor.
And as the upper surface of coverture 2, its rubber surface has a pre-service, such as soaking into, scrubs, spray, or the like.The surface of coverture 2 has the effect of low friction factor to increase surperficial frictional resistance.Therefore, to strike at feeling on the electronics drum 1 similarly be to strike on metal primary sound drum to waddy.And electronics drum rubber surface resistance after knocking a period of time can be reduced.The material of making coverture 2 is handled with upper surface the same advantage, and more soft than the quality of first framework that will describe afterwards.In addition, surface treatment applies to the outer too such as the rubber surface pre-service and knocks part.By using coverture 2 to cover first framework, making good elasticity is arranged when knocking the upper surface of electronics drum 1.
Shown in Fig. 3,4, be used for the bolt part 10a from the support bar 10 of following support electronics drum 1,13, one felt washers 12 of the wing nut on the 10a on the opening shape center 1a of electronics drum 1, are arranged in this order.
First framework 3 comprises that simultaneously by outer part 3b, decline step 3a forms the periphery of first framework 3.The outer part 2b of the coverture 2 that contacts with decline step 3a is thicker than the coverture 2 that contacts with first framework 3 outer part 3b.In order that blanket surface is flat condition.By forming decline step 3a, first framework 3 has formed irregular vibration, drives outer part 3b.Therefore, rock and can restore to the original state rapidly later.So,, also can accurately detect position of knocking and the dynamics of knocking each time even knock electronics drum 1 continuously.In addition, the shape of upper surface is identical with primary sound crash sheet, has guaranteed to knock really feel.
In addition, because obducent outer part 2a outwards extends to the back side of the outer part 3b that encases first framework 3.Small cymbals limit part 32 zones (as shown in Figure 1) easy deformation when knocking.Therefore, might the regenerate distortion back, marginal portion of realistic simulation primary sound a crash sheet absorbs the process of impulse force.
Between outer sensor and first frame upper surface, place a flexible film, can effectively avoid knocking the interference of small cymbals in the face of the small cymbals limit.Furtherly, because first framework is that the hard material is made, under some situation, knock the vibration that the small cymbals face can drive the small cymbals limit, cause small cymbals limit sounding thereby trigger the upper edge sensor, promptly the small cymbals face knocks and can disturb the small cymbals limit.For avoiding above-mentioned situation, above first framework, place the film that a soft materials is made, make buffering usefulness, knock small cymbals in order to absorption and wear vibration, thereby avoid the upper edge sensor output signal to the small cymbals limit;
The support openings part 4e of second framework 4 and wedge shape shrinkage pool assembly 9 break away from, and 9 conducts of wedge shape shrinkage pool assembly are body one by one, are placed on the below of the opening part of first framework.
For preventing that the electronics drum from spinning, can recover rapidly after knocking steadily, at the lower surface of first framework, be the center of circle with first frame center opening, along the circumferential direction, equidistantly placed several iron blocks 6 that weight is the same, with the fixing iron block of screw and peripheral framework.By rapid braking, just can effectively avoid the influence of knocking instantly, thereby guarantee the output correctness of knocking continuously knocking next time.
In addition, first framework and second framework can be made as integral structure, are referred to as framework.
In addition, outer sensor 7 be placed on first framework 3 outer 3b upper surface and be covered between the coverture 2 on the 3b of outer.Outer sensor 7 detects knocking from small cymbals limit part 32 (as shown in Figure 1).
Shown in Fig. 3,4, support openings part 4e is placed on the below at lower surface center of the central opening part of first framework 3.The peripheral edge and the support openings part 4e of wedge shape shrinkage pool assembly 9 are overlapping, and place the top of support openings part 4e.In addition, wedge shape shrinkage pool assembly 9 has a perforation 9a, and the support bar 10 that supports electronics drum 1 enters from below by described perforation 9a.The shape of wedge shape shrinkage pool assembly is that bore progressively reduces from the bottom to top.Wedge shape shrinkage pool assembly is in the middle of first framework and second framework, and is fastening in addition with bolt.Simultaneously, support bar 10 has a tip portion 10b to be embedded in the perforation 9a, and therefore, the shape of support bar 10 also is progressively to reduce diameter at tip portion.Rotation brake assembly 11 is fixed by firmware 15 and support bar 10, makes the tip portion 10b of support bar 10 can be embedded in rotation brake assembly 11.The head of rotation brake assembly 11 is lozenges, and the head of this assembly is sharper more than the tip of wedge shape shrinkage pool assembly 9.Based on this, wedge shape shrinkage pool assembly 9 can not exclusively be fitted in swing on the rotation fixation kit 11.Therefore, when the electronics drum was knocked, it can effectively limit the percussion vibration amplitude, and can reduce the scope that sensor exceeds the dynamics of knocking thus, thereby reduced manufacturing cost.Because wedge shape shrinkage pool assembly uses the material more more soft than first framework and second framework to make, such as rubber.Wedge shape shrinkage pool assembly 9 has distortion slightly when the electronic drum disc vibration, thereby has prevented the damage of electronics drum, and guarantees effectively braking.In addition, the tip portion of support bar 10 is bolt part 10a.Bolt part 10a is positioned at the top of support bar 10, extend out to the top of the central opening part of first framework 3, and then can fix by dish shape nut 13 and live in half framework 3.Felt washer 12 passes bolt part 10a, is placed in the middle of the central opening part of dish shape nut 13 and first framework 3.The electronics drum is fixed on the support bar 10 by dish shape nut.
Come from piezoelectric sensor 5, outer sensor 7 separately transmission output signal to the output port 18 and the output cable 14 (as shown in Figure 5) of audiogenic device (not marking among the figure).When knocking electronics drum 1, the center that has produced with electronics drum 1 is the vibration of vibrating shaft.Output port 18 is not placed on the zone near centre of oscillation axle, but laterally.Output port 18 and output cable 14 are placed near the zone of centre of oscillation axle so that its center of gravity near the center of gravity of drum, because there has been iron block 6 can offset the gravity of output port and output cable.Is to make the convenient plug of player with output port towards another major reason in the outside.Output port 18 and output cable 14 are positioned at the side away from support bar 10, can avoid the output cable 14 of electronics drum to twine on support bar 10 like this, also can avoid because the drawing of support bar influences the cable output signal.Output port 18 is placed between the lower surface of the arm structure 4c of second framework 4 and first framework 3, is fixed on second framework 4 by the output port support.Come from each signal of sensor and be output,, be sent to audiogenic device (not marking among the figure) through output cable 14 from output port 18.Be embodied in,, can be transferred into audiogenic device from the signal of each sensor although the quantity of the quantity of sensor and terminal is inconsistent.
What Fig. 5 showed is the upward view of electronics drum.Coverture 2 wraps the outer of first framework.Showed simultaneously thereby how support bar 10 passes through fixedly rotation brake assembly 11 support electronics drums 1.Second framework 4 fixes first framework by some bolts 16 from lower surface.
Fig. 6 is a width of cloth design sketch, has showed electronics drum small cymbals heart part 30, is positioned at the small cymbals face portion 31 in the middle of the small cymbals heart and the small cymbals limit, and the situation of the small cymbals limit part 32 of outer when being knocked by waddy 20.Fig. 7 is a width of cloth design sketch equally, thereby has showed that the outward flange that pinches electronics drum 1 with hand produces the situation of vexed sound.
If conducted to the electronics drum as figure Fig. 6 and shown in Figure 7 knocking with vexed sound, piezoelectric sensor 5, outer sensor 7 detects vibration and knocks dynamics.The signal that comes from output port 18 by output cable 14, transfers to source of sound (not marking among the figure) with signal.Audiogenic device has been preserved from the analog sampling tone color of primary sound crash sheet corresponding region sampling.Such as drum face (small cymbals face) tone color, drum limit (small cymbals limit) tone color.The zone of corresponding primary sound drum is an example with the small cymbals sheet respectively, the small cymbals face portion 31 between the promptly corresponding small cymbals heart and the small cymbals limit, the small cymbals limit part 32 (as shown in Figure 1) of outer, the tone color when being knocked.Export in the lump by output cable 14 based on output signal, audiogenic device produces and knocks tone color or vexed audio really corresponding to each zone.
Correspondence is knocked each zone or is carried out vexed sound operation, and the output situation of each sensor is as shown in the table:
| |
|
|
| Knock bulging face | Output | ------ |
| Knock bulging limit | Output | Output |
| Vexed sound operation | ------ | Output |
If small cymbals face portion 31, small cymbals limit part 32 (as shown in Figure 1) is knocked, and this piezoelectric sensor 5 all can be exported a signal; When the marginal portion stopped to vibrate, piezoelectric sensor 5 can cut out.Similarly, when the player knocked bulging face portion 31 on the electronics drum, outer sensor 7 can not exported a signal; When the player knocks bulging limit part 32 or pinches bulging limit part when making it to stop to vibrate, outer sensor 7 can signal of output.
Fig. 8 is the circuit diagram of corresponding sensor output signal to the port section of source of sound.3 terminal A1, the A2, the A3 that connect output port have been showed.Output signal from piezoelectric sensor 5 is sent to terminal A2.Output signal from outer sensor 7 is transferred into terminal A3.
Following table has been showed the corresponding relation between the tone color of each terminal and appointment:
As shown in Figure 8, only use an output port.Be used to detect that bulging face knocks, knock on the drum limit, vexed sound operation.
Analog sensor can use the sensor of resistance type sensor, inductive type sensor, capacitance type transducers and other output analog quantity.Below adopting resistance type sensor is example explanation detection mode and principle.The characteristic of resistance type sensor is that resistance and the dynamics of knocking are ratio.Determine the dynamics of knocking to produce different volumes by the size of detected resistance.
The drum face knocks: beat on the bulging face regional location of drum (non-bulging edge regions), at this moment outer sensor 7 does not have conducting, and terminal A2 has signal output, and 3 pin are open circuit (resistance infinity) output.
Knock on the drum limit: beat on position, drum limit, and outer sensor 7 conductings at this moment, terminal A2 has signal output, and terminal A3 output resistance is the resistance value of knocking outer sensor 7.
Vexed sound: pinch position, edge (small cymbals limit) with hand, outer sensor 7 conductings at this moment (time is long), terminal A2 does not have signal output, and terminal A3 output resistance is the resistance value of pushing outer sensor 7.
Terminal A3 mouth does not have signal output if the terminal A1 mouth of output port has the output signal output of piezoelectric sensor 5, then produces drum face tone color.Terminal A2 mouth has signal output if the terminal A1 mouth of output port does not have the output signal output of piezoelectric sensor 5, then produces vexed sound tone color.
In addition, the embodiment of the utility model scheme is: if the terminal A3 mouth of output port has output signal output, whether tube terminal A2 does not have signal output, only needs promptly can judge vexed sound of generation or drum lateral look according to the output signal size of terminal A3 mouth or the length of output time.That is to say, according to knocking bulging limit and to pinch the employed dynamics in bulging limit different, thereby export different resistances, can judge by resistance to produce vexed sound also or drum lateral look, and the sound size of drum lateral look.Perhaps, permanent according to the vexed sound duration, and it is very brief to knock action time, thus externally circuit was judged the time, and then confirm to produce vexed sound or drum lateral look.
Generally use the switching mode sensor as the upper edge sensor at present, be used to detect beating position, piezoelectric sensor 5 detects the dynamics of knocking, and produces drum lateral look and dynamics in conjunction with upper edge sensor and piezoelectric sensor 5.The drawback of doing like this is and need be judged each port output by program, could produce the tone color that meets the dynamics of knocking.
Based on this, this programme adopts single resistance type sensor as the upper edge sensor, detects the dynamics of knocking and the vexed sound on drum limit respectively, and then the generation real simulation knocks dynamics drum lateral look and the operation of vexed sound.Compare with traditional method, simplified the circuit signal processing, vexed audio fruit also can quickly respond to.In addition, when drum lateral look produced, drum face tone color can not produced simultaneously, had effectively avoided bulging limit to knock the interference that the drum face is knocked.
A kind of scheme:, outer sensor 7 can be used as switch equally, only the detection position according to the output resistance thresholding.If the terminal A3 mouth of output port and A2 mouth all have output signal output, then produce drum lateral look, piezoelectric sensor 5 detects the dynamics, output drum lateral look sound size of knocking.Terminal A3 mouth has signal output if the terminal A2 mouth of output port does not have output signal output, then produces vexed sound tone color.At this moment, the output in conjunction with piezoelectric sensor 5 and outer sensor 7 can detect vexed sound operation (small cymbals limit part stops vibration) immediately.Because the operation of vexed sound pinches drum by hand and produces, thereby triggers outer sensor 7, send signal, thus needn't placement sensor at the lower surface of framework, thus cost saved.
Use " jack " about drum delivery outlet shown in Figure 8 thus replace the progressive point of traditional " two jacks ":
1, the trouble of effectively avoiding two line wrongs to bring;
2, save the drum connecting line;
3, save audiogenic device panel jack number, thereby save panel space;
4, simplify handled easily;
As mentioned above, be positioned at the middle bulging face portion 31 of the bulging heart and drum limit if knock, signal can output signal to audiogenic device from the A2 terminal port, and sends bulging face tone color.If knock drum limit, the outer part 32 of electronics drum, signal can output signal to audiogenic device from the A3 terminal port, and sends bulging lateral look.
And, as shown in Figure 7, knocking marginal portion (vexed sound operation) by what pinch electronics drum 1 with hand, the signal of outer sensor 7 by terminal A3, is transferred into audiogenic device, thereby produces vexed audio fruit.
As another kind of scheme: outer sensor 7, if its resistance of resistance type sensor of using is inverse ratio with the dynamics of knocking, the dynamics of knocking is big more, resistance is more little, and its variable Standard resistance range is less.Therefore, when little dynamics is knocked, can be with its sensing equipment as inspecting force; When great dynamics knocks owing to reached ultimate value, survey this moment resistance can't embody the dynamics of knocking really and change, promptly can be used as switch and detect.That is: use outer sensor 7 inspecting force sizes when little dynamics is knocked; When knocking, uses great dynamics piezoelectric sensor 5 inspecting force sizes.
Below that narration is the 2nd embodiment of the present utility model:
Fig. 9 has showed another characteristics of this utility model electronics drum 21.Knock bulging face, drum limit, the operation of vexed sound except in electronics small cymbals sheet, using, other electronics drums in drum kit, as can use bulging face in army's drum equally, knock on the drum limit and the operation of vexed sound.Fig. 9 has showed a framework 23 and has covered the coverture of the upper surface of framework 23.Outer part 23a is similar to electronics drum 1, is in the outer part of the framework 23 of electronics drum 21.Coverture 22 wraps from the outer with framework 23, and is similar to electronics drum 1.Be placed on the outer sensor 7 of the outer part 23a of framework shown in Figure 9 23, consistent with last embodiment on type.
The outer sensor 7 that Fig. 9 shows is placed on the position range of corresponding sensor in the described electronics drum 1 of a same embodiment.
