Abstract
The invention discloses a noncontact triggering-type electronic drum head. The drum head comprises a framework and a conductive first drumhead, wherein the first drumhead is spread on the framework. The drum head also comprises a second drumhead, wherein the second drumhead is arranged above the first drumhead, and the second drumhead is naturally bonded with the first drumhead after being spread on the framework. An elastic buffering layer which is simultaneously contacted with the two drumheads is also arranged between the first drumhead and the second drumhead. The noncontact triggering-type electronic drum head is used as a polar plate of a capacitance-type sensor of an electronic drum, so that the flexibility in detection is greatly improved; and meanwhile, the drumheads and the framework form a favorable conductor which can be conveniently grounded, so that a shielding effect on the internal noncontact sensor can be realized, and the interference resistance can be improved. In addition, the drum head adopts a two-layer form of the conductive first drumhead and the second drumhead, and different resonance frequencies of the first drumhead and the second drumhead can also realize an effect for absorbing the shock and reducing the lingering sound, so that the accuracy in signal detection can be improved.
Description
Technical field
The present invention relates to the electrophonic musical instrument technical field, relate in particular to a kind of drum head that is used for electronic drum.
Background technology
Electronic drum belongs to electronic percussion instrument, and it will hit the mechanical signal that produces and pick up into source of sound through trigger, and source of sound becomes required tone color with conversion of signals, becomes the sound that people's ear can be heard through audio amplifier or earphone again.
Present electronic drum mainly adopts the contact trigger; Usually adopt piezoelectric ceramics as transducer; Two ends with an elastic supporter (sponge, bipeltate etc.) are withstood bulging face and piezoelectric ceramics respectively, convert mechanical signal to electric signal thereby hitting power is passed to piezoelectric ceramics.The shortcoming of this sensing mode is that transducer exists entity contact with drum between the face, and signal response has significantly non-linearly near contact point, is embodied in same hitting dynamics, electric signal increase several times in this zone.This by the even response characteristic that causes of touch sensor inequality signal, be incongruent obviously with real primary sound drum.
The contactless triggering that grows up at present comprises that condenser type and electromagnetic type trigger, and condenser type and electromagnetic type trigger the variation through electric field or magnetic field between detection transducer and the drum head, produce corresponding electric signal.But the noncontact flip-over type drum head that adopts at present adopts polyester or organic material more, and this drum head causes electric field or magnetic field directly to penetrate, so sensitivity is not high.
Summary of the invention
The objective of the invention is to above-mentioned deficiency, the electronic drum drum head that provides a kind of highly sensitive noncontact to trigger to existing electronic drum drum head.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of noncontact flip-over type electronic drum drum head, drum head comprise the first drum face of a framework and a conduction, and first brace is opened up on said framework.
Further, drum head also comprises the second drum face, and the second drum face is positioned at the top of the first drum face, and the second drum face and the first drum face are fitted after support exhibition on the framework naturally.The first drum face and second rouses can also be provided with the elastic cord breaker that contacts with two drum faces simultaneously between face.
The first drum face comprises following three kinds of forms: (1) first drum face is a conductive mesh; The surface recombination of (2) first drum faces has a conductive coating; (3) first drum faces are made into by conductive fiber and non-conductive fibre at interval, or the first drum face is made into by the conductive fiber that is coated with protective seam.
Preferably, the order number of the first drum face is the 40-160 order, and the resistivity of framework is less than 0.1 ohm meter, and the resistivity of the first drum face is less than 0.1 ohm meter, and the resistance that framework is arrived in the center of the first drum face is less than 10
6Ohm, the thickness range of the first drum face is the 0.1-1.0 millimeter.
Noncontact flip-over type electronic drum drum head disclosed by the invention is as a pole plate of the capacitance type sensor of electronic drum; Greatly improved detection sensitivity; And, guaranteed that electronic drum knocks diverse location and all can in time produce response signal delicately owing to adopt whole bulging face as a pole plate; Simultaneously, drum face and framework are formed good conductor, ground connection easily, thus internal sensor is produced shield effectiveness, the raising antijamming capability.In addition, during the two-layer form of the first drum face that adopts conduction when drum head and the second drum face, the difference of the two resonance frequency can also play weakening, reduce the effect of lingering sound, thus the accuracy of raising input.
