Specific embodiment
Below with reference to Fig. 1 to Fig. 6, the utility model is described further:
As depicted in figs. 1 and 2, the netted electronic drum of the utility model includes that drum disk body 10, drum circle 1, wire side 2, data are adopted
Collect module and data processing module.
Data acquisition module includes trigger and transmitting medium, and transmitting medium is magnetic part 31, and magnetic part 31 is arranged
In a kind of flexible material layer 3, trigger includes and the non-contact matched Hall sensor 51 of magnetic part 31.
Wire side 2 is formed by stacking by three-layer network surface layer, and the side wire side close to the flexible material layer 3 comprising magnetic part 31 is
Wire side 2 is fixedly mounted on drum disk body 10 by white, drum circle 1.Hall sensor 51 is mounted on the lower surface of 5 plate of a pcb board
On, flexible restorer layer 4 is adhered in the upper surface of pcb board 5, and pcb board 5 is placed on the first soft foamed damping material layer 6
In mounting hole, the second soft foamed damping material layer 9, the second soft foaming are equipped with below the first soft foamed damping material layer 6
Cushioned material layer 9 is attached in fixed plate 7, and fixed plate 7 is fixed on drum disk body 10 by screw 71.
Flexible material layer 3 equipped with magnetic part 31 is attached to elastic 4 upper surface of restorer layer, and Hall sensor 51
In the underface of magnetic part 31, the flexible material layer 3 equipped with magnetic part 31 and the pcb board 5 equipped with Hall sensor 51 are same
The heart and by elastic restorer layer 4 by equipped with Hall sensor pcb board 5 and flexible material layer 3 that magnetic part 31 is housed it is complete
Separate entirely.
1, flexible material layer 3: it can be silicon rubber, such as: its shore hardness is 30 °, and fixed magnetic component 31 is used,
Elastic force is good after drum stick taps.
2, elastic restorer layer 4: it can be sponge, density 22kg/m3, material softness is softer, is compressed by external force
Resilience is good afterwards, rebound is fast.
It acts on one: because drum disk body trigger signal principle is exactly that magnetic part 31 and the Hall chip 51 of lower section pass through not
Disconnected distance changes so that magnetic flux, which changes, generates sine voltage signal, therefore selects sponge to realize this function.
Effect two: elastic restorer layer 4 is contacted with wire side 2 due to elastic force Quick-return and again after downward vibration, is not being continued
Second of vibration will not be generated in the case where stress, will not continue to generate signal.
3, the first soft foamed damping material layer 6: its material is that neoprene foaming material (is commonly called as: gram Hui Li, also known as CR
Foam), such as: hardness can be 15 °.
Its first effect: it is fixed with the PCB 5 of Hall chip；Second effect: the dynamics when drum stick taps wire side 2 reaches
Flexible material layer 3, then shake elastic restorer layer 4 back and forth and change distance, the first soft foamed damping material layer 6 makes to tap
Dynamics further weaken, when reaching the first soft foamed damping material layer 6, dynamics further weakens or absorbs；Third
Effect: when tapping drum circle 1 or drum disk body 10, tapping the vibrational energy of generation in addition to being incuded by sensor 8, can also be upwards
Flexible material layer 3 and magnetic part 31 conduct, and the first soft foamed damping material layer 6 can be absorbed vibrational energy and avoid magnetism
Component 31 is affected.
4, the second soft foamed damping material layer 9: its material is that neoprene foaming material (is commonly called as: gram Hui Li, also known as CR
Foam), hardness is the same as the first soft foamed damping material layer 6.It plays the dynamics that further decrease above-mentioned steps are transmitted through
0, do not reach it on drum disk body 10, because the triggering of drum circle 1 or drum disk body 10 is the biography by being fixed on drum disk body 10
Sensor 8 incudes generation signal, and such as striking wire side 2 has signal to reach drum disk body 10, then will appear the signal on crosstalk side.Similarly,
It can also decay and absorb the influence to flexible material layer 3 and magnetic part 31 upwards after drum circle 1 or drum disk body 10 tap.
In short, the circle 1 or when drum disk body 10 of beating a drum, the vibration signal of drum circle 1 or drum disk body 10 passes through the second soft hair
Bubble cushioned material layer 9 reaches the first soft foamed damping material layer 6, then reaches elastic restorer layer 4, finally reaches soft material
The bed of material 3 beats a drum circle 1 or the dynamics of drum disk body 10 decays step by step, elasticity is made to restore material because using foamed damping material
The bed of material 4 is substantially shockproof, will not generate distanceization, i.e., will not generate magnetic flux change, does not have voltage signal generation, avoids
The case where percussion side crosstalk face.
Hardness compares: the first soft foamed damping material layer 6 and the second soft 9 hardness of foamed damping material layer are both greater than bullet
Property restorer layer 4.
When tapping wire side 2, the magnetic part 31 in flexible material layer 3 generates downward vibration, magnetic part 31 with
The distance of Hall sensor 51 changes, and the magnetic field range that Hall sensor 51 senses generates variation, thus generates audio
Voltage signal is exported to data processing module, and data processing module handles the audio voltage signal received, obtains institute
The audio signal needed and output.
After tapping wire side 2, elastic restorer layer 4 wire side 2 under after shaking downwards due to elastic force Quick-return and again
It is secondary to be contacted with wire side 2, second of vibration will not be generated in the case where not continuing stress, would not also continue to generate signal.Cause
This flexible material layer 3 withstands wire side 2, also avoids generating mechanicalness noise when tapping wire side.
It, can be complete by smelting tool since Hall sensor 51 and magnetic part 31 are indirectly fixed on drum disk body 10
All risk insurance demonstrate,proves Hall sensor 51 and magnetic part 31 is concentric, substantially increases wire side signal in this way, avoids Chinese patent (application
Publication No.: CN106531139A) the netted electronic drum announced is because Hall sensor and magnetic material are respectively caused by different components
Mutual deviation causes that lesser signal can only be generated wire side shakes, and each 10 signal of drum disk body is variant, drum disk
10 sensitivity of body is low.

The prime signal amplification circuit includes first resistor (R1), second resistance (R2), 3rd resistor (R3), the 4th resistance
(R4), the 5th resistance (R5), first capacitor (C1), the second capacitor (C2), third capacitor (C3) and triode (Q1)；
One end of first capacitor (C1) is that the input terminal of prime signal amplification circuit is connect with Hall sensor (51), hall sensing
Device (51) is also connect with power output end, and the other end of first capacitor (C1) is connected with one end of first resistor (R1), the first electricity
The resistance other end of (R1), one end of second resistance (R2), 3rd resistor (R3) one end connected with the base stage of triode (Q1), the
Power supply, the second capacitor are accessed in one end of the other end of two resistance (R2), one end of the 4th resistance (R4) and the second capacitor (C2)
(C2) other end ground connection, the other end ground connection of 3rd resistor (R3), the collection of the other end of the 4th resistance (R4), triode (Q1)
Electrode is connected with the one end of third capacitor (C3), one end connection of the emitter of triode (Q1) and the 5th resistance (R5), and the 5th
The other end of resistance (R5) is grounded, when the other end of third capacitor (C3) is the output end of prime signal amplification circuit, the circuit
Hall sensor is amplified with the audio voltage signal that magnetic range provides makes it meet wanting for audio input signal
It asks.
