Small cymbals displacement detector is stepped below by what specific embodiment was further described the utility model.
Embodiment one
As shown in figure 5, in first embodiment, the small cymbals displacement detector 5 of stepping on of the utility model includes:
Upper cover 55 is provided with upper cover pilot hole 55b.
Slide unit 53 is fixed on 55 lower section of upper cover, including hollow sliding part pilot hole 53b.
Pedestal 58 is arranged below the slide unit 53, has hollow guide post 58a, the sliding part pilot hole
53b is set on the guide post 58a.Wherein, the guide post 58a is fixed on the pedestal 58, or detachable
Ground is arranged on the pedestal 58.
Flexible restoring organ 59 is placed between the pedestal 58 and the slide unit 53, for the slide unit
Restoring force is provided.Preferably, the flexible restoring organ 59 uses spring, is set on the guide post 58a.Certainly, described
Flexible restoring organ 59 can also use other structures, be fastened on the slide unit 53.
Elastomeric element 54 is fixed on 53 lower section of slide unit, is set on the guide post 58a.
Step on small cymbals displacement detection part, including elastomeric element 54 and displacement detecting circuit 57.As shown in Figure 6 and Figure 7, the bullet
Property component 54 include at least two protrusion 54a, have deformation space 54b inside the protrusion 54a.The protrusion 54a tool
There is mutually different protrusion height h, wherein h indicates the maximum distortion height of protrusion 54a.Institute's displacement detection circuit 57 includes
Sensor 56, the sensor 56 include at least two detection switch in parallel；The detection switch and one or more protrusions
Portion 54a is corresponding.As shown in figure 8, in this embodiment, the detection switch includes SW1~SW8.Preferably, described at least two
A protrusion 54a is along axially uniform setting, to guarantee that the elastomeric element 54 keeps balance in the horizontal direction.
Specifically, when it is described step on small cymbals small cymbals piece 4 to bottom offset when, the slide unit 53 slide downward therewith.It is described to step on small cymbals
After small cymbals piece 4 moves down into extreme position, the flexible restoring organ 59 and elastomeric element 54 provide upward restoring force, the restoring force
The slide unit 53 is followed to step on small cymbals small cymbals piece 4 and reply together.
Institute's displacement detection circuit 57 further includes the resistance of displacement detecting terminal and preset quantity, the electricity of the preset quantity
Resistance series connection, the detection switch are connected in parallel on the resistance both ends of the preset quantity；The displacement detecting terminal with it is described concatenated
Detection switch is connected, for detecting the displacement for stepping on small cymbals.As shown in figure 9, in this embodiment, the resistance include R1~
R7.Wherein, the number of the resistance fewer than the number of the detection switch 1.Specifically, circuit conducting after detection switch closure
Priority are as follows: SW1 < SW2 < SW3 < SW4 < SW5 < SW6 < SW7 < SW8.53 He of slide unit is driven when the small cymbals piece 4 moves down
When the elastomeric element 54 moves down together, the protrusion 54a of the elastomeric element 54 makes the switch of displacement detecting sensor 56
SW1 is closed first, SW1 closure after resistance and be R1+R2 ...+R7；The protrusion 54a of elastomeric element 54 continue to move down so that
Switch SW1, SW2 of sensor 56 are closed, because the priority of SW2 is higher than SW1, circuit conducting at this time passes through SW2, resistance resistance
Value and be R1+R2 ...+R6；And so on, after detection switch is all closed, resistance and be 0 Ω.Can thus it pass through
The linear variation of resistance value of turning circuit after adjustment resistance value guarantee detection switch is successively closed.Furthermore it is possible to according to reality
Need to increase and decrease the detection switch quantity in displacement detecting sensor 56, corresponding resistance quantity changes therewith.The displacement detecting
Circuit 57 obtains the displacement for stepping on small cymbals small cymbals piece 4 by detecting the electric signal of 56 two sides of sensor.As shown in Figure 10, institute
The variation of the small cymbals piece stroke and resistance of acquisition tends to linear change.
In an embodiment of the present invention, at least two detection switch is symmetrical arranged along the guide post.Specifically
Ground, each detection switch are arranged around axis, and the resilient lugs 54a of adjacent height along axisymmetrical or is staggered as far as possible, this
Sample can balance reaction force when resilient lugs 54a pressure deformation, so that reaction force more symmetrical equilibrium acts on
On slide unit 53,53 run-off the straight by unbalanced force of slide unit is avoided.It is each to switch corresponding elasticity in the present embodiment
Protrusion height relationships are as follows: SW1 > SW2 > SW3 > SW4 > SW5 > SW6 > SW7 > SW8.
In an embodiment of the present invention, the maximum height h of the deformation space inside the protrusion is not less than described
Step on the effective travel of small cymbals.When it is described step on small cymbals small cymbals piece 4 and move down into extreme position after, the elastomeric element 54 has deformation space 54b,
Thus elastomeric element 54 generates lesser screen resilience, so that pedal has the consolidation sense for being pressed onto bottom, to improve the foot of user
Feel
For electrophonic musical instrument, for stepping on small cymbals particularly with electroacoustic, feel determines whether player can show freely and drills
Perform method.Excessive bounce cannot be had by stepping on consolidation sense to be had and being not easy to shake.How this practical novel main difficulty makes
When must step on that detection switch (sensor) is successively closed when small cymbals moves down, latter detection switch is not influenced after previous detection switch closure
Closure；It is (previous closed when i.e. the latter elastomeric element is depressed while the bounce of elastomeric element is as small as possible
Elastomeric element cannot generate excessive bounce), it also can guarantee that elastomeric element can provide the power of enough detection switch closures.Cause
This, needs to debug the wall thickness and hardness of elastomeric element.In an embodiment of the present invention, the elastomeric element 54 uses Shao
Silica gel or rubber of family name's hardness between 25HA~70HA are made.The protrusion wall thickness is 0.3mm~2.5mm.

Protrusion, protrusion have the space of deformation, and deformation space is not less than the effective travel for stepping on small cymbals；Protrusion has different height
Degree, when slide unit drives elastomeric element to move down, protrusion successively contact sensor；Sensor is opened by multiple in parallel
It closes region to constitute, each switch region is pressed in by protrusion, is closed it successively；Therefore, different using protrusion height, it can make
Small cymbals stroke and the linear variation of resistance must be stepped on, so as to accurately detect the displacement for stepping on small cymbals；After small cymbals piece moves down into extreme position, bullet
Property resetting-mechanism and elastomeric element restoring force is provided, which allows slide unit that small cymbals piece is followed to reply together；Because
The protrusion of elastomeric element has deformation space, after small cymbals piece moves down into extreme position, generates lesser screen resilience, not will cause and step on
Plate is not pressed onto the consolidation sense at bottom, to improve the feel of user.Therefore, the utility model effectively overcomes in the prior art
Various shortcoming and have high industrial utilization value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
