Abstract
The invention discloses a noncontact triggering-type electronic drum. The electronic drum comprises a drum shell, a drum head which is spread on the drum shell and a capacitance-type sensor which is fixedly arranged on the drum shell and is spaced from the drum head, wherein the drum head at least comprises a first drumhead, and the first drumhead is conductive. The electronic drum utilizes the conductive drumhead and the capacitance-type sensor to generate a response signal, and no physical contact exists, so that the response signal is more approximate to the real natural drum; meanwhile, the electronic drum utilizes the entire drum head as a polar plate, so that the response signal can be sensitively generated when different positions of the electronic drum are beaten; the drum head is conductive, so that convenience for grounding shielding of the electronic drum is realized, and the interference resistance of an electronic drum trigger can be improved; and in addition, the drum head adopts a two-layer form of the conductive first drumhead and a second drumhead, and the resonance frequencies of the first drumhead and the second drumhead are different, so that an effect for absorbing the shock and reducing the lingering sound also can be realized, and the accuracy in detection can be realized.
Description
Technical field
The present invention relates to the electrophonic musical instrument technical field, relate in particular to a kind of noncontact flip-over type 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.
The trigger of electronic drum is mainly the contact trigger at present; 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.
Summary of the invention
The objective of the invention is to provides a kind of electronic drum of noncontact flip-over type to the above-mentioned deficiency in the existing electronic drum.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of noncontact flip-over type electronic drum comprises that a drum shell, the drum head, of a support exhibition on the drum shell are fixed on the bulging shell and drum head non-contact sensor at regular intervals, and drum head comprises the first drum face of conduction.
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 of electronic drum drum head comprises following several kinds of composition 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.
Particularly, be provided with a sensor holder in the electronic drum in order to fixing non-contact sensor, non-contact sensor is capacitance type sensor or electromagnetic sensor.Electronic drum also comprises a drum head holder, and the drum head holder is fixed on the bulging shell, also can drum head holder and drum shell directly be processed into one.Electronic drum also comprises a drum head trim ring, and the drum head trim ring is fixedly connected with the drum head holder through gib screw, and the edge after the brace exhibition is fixed in the drum head trim ring.
Noncontact flip-over type electronic drum disclosed by the invention is unsettled between its sensor and the drum face, does not have the entity contact, so signal response is more near real primary sound drum; Adopt whole drum head as a pole plate, guaranteed that electronic drum knocks diverse location and all can in time produce response signal delicately, and, made things convenient for grounded shield, thereby improved the antijamming capability of electronic drum trigger because drum head conducts electricity; In addition, during the two-layer form of the first drum face that adopts conduction when drum head and the second drum face, the resonance frequency difference of the two can also play weakening, reduce the effect of lingering sound, thus the accuracy of raising input.
