Abstract

The utility model discloses a double rail inductor for electronic keyboard music instrument. It uses non-equidistance induction points with independent induction electric signals to replace equidistance induction points sharing electric signals for black keys and white keys in electronic keyboards. Electric signals generated by black keys are processed by black key signal inductors while electric signals generated by white keys are processed by white key signal inductors. Therefore, induction points of each independent inductor in the double rail inductor can be located close to pressure position of black and white keys so as to more realistically reflect key pressure's control on volume of electric pianos and improve the sensitivity of the keys.

Description

The special-purpose double track inductor of electric keyboard instrument

Technical field

The utility model relates to a kind of keyboard musical instrument, is meant the double track inductor of a kind of Electronic Keying disc type musical instrument special use especially.

Background technology

The keys of keyboard of conventional keys disc type electronic musical instrument is arranged and all is made up of black key, Bai Jian, the electric signal induction point of black key, Bai Jian all is located on the same line, power by shared signal deteching circuit plate induction key changes, through the processing of a series of electronic technology, the electrical signal conversion that power is changed becomes fender qin tone signal.Because the electric signal of this keyboard-type electronic musical instrument black key, Bai Jian induction point is located on the same line, the dynamics that causes the player to point playing key and fender the strong and weak wayward of volume that pronounce, the sensitivity of button is low.And fulcrums black, white two class key lever systems are different, the stroke itself that descends is also different, the angle of inclination that forms is also different, can apply the pressure of different angles to the sense electrical signal induction sensor on the induction of signal circuit board, causes the performance of product and serviceable life to be reduced a lot.

Summary of the invention

The purpose of this utility model is to provide a kind of double track inductor of electric keyboard instrument special use, and it can improve the weak sensitivity that changes of key control qin loudness of a sound, manufacture craft simple possible comprehensively.

In order to achieve the above object, the utility model is realized by following technical scheme.

The special-purpose double track inductor of a kind of electric keyboard instrument, the induction point of the unequal distance of two classes is arranged in the shared equidistance of the electric signal induction point positions primary electron keyboard is black, white two class keys, independent separately electrical signal of reaction, wherein, the electric signal that black key produces is finished by the black key signal inductor, and the electric signal that Bai Jian produces is finished by white key signals inductor.

The beneficial effects of the utility model are, adopted the special-purpose double track inductor of the utility model electric keyboard instrument, the variation of black, the white key displacement of double track inductor induction is that the inductor that is provided with the not equidistant induction point of two classes is respectively finished, like this, in the double track inductor separately independently the induction point of inductor just can accomplish force application part position near black, white key.Compare with old-fashioned single track inductor, the position of induction point is provided with more rationally in the inductor, and truer reflection key dynamics is to the power control of fender pronunciation volume.The double track inductor of different induction points, the difference of black, white key descending stroke in the time of can remedying performance fully, black key, Bai Jianke take into account simultaneously, improve button sensitivity.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is further elaborated.

The special-purpose double track inductor of a kind of electric keyboard instrument as shown in accompanying drawing 1, accompanying drawing 3, accompanying drawing 4 has been fixed preceding sleeper 5, middle sleeper 12, key key tail chock 13 respectively on keyboard base 19.In accompanying drawing 3, accompanying drawing 4, old-fashioned preceding sleeper 5 is resolved into sleeper 9 before Bai Jianqian sleeper 6 and the black key, form white key 4, black key 3 keying board slots 20 between the two.Bai Jianyuan clasp nail 7 and black key circle clasp nail 10 have been installed on the sleeper 9 before preceding sleeper 5, Bai Jianqian sleeper 6, the black key, and mix the Bai Jianda circle 8 and the big circle 11 of black key that damping uses respectively in the bottom of circle clasp nail, the main effect of circle clasp nail mainly is to limit the key double swerve.Black key wire nail 1 and white key wire nail 2 have been installed on the middle sleeper 12, and the function of wire nail is to guarantee that key is a fulcrum with the wire nail position, forms separately independently key lever system.Space between middle sleeper 12 and preceding sleeper 5 (or and black key before sleeper 9) forms black key, middle sleeper keying board slot 21.Paste key tail 14 on the key key tail chock 13, their effects one together are to support key, the 2nd, and damping in key is replied.

Embodiment 1

As shown in Figure 1, accept traditional structure, on the basis that sleeper 5 is complete before keeping, the double track inductor is installed in black key, middle sleeper keying board slot 21.In black key, middle sleeper keying board slot 21, the installation of white key inductor 23 is positioned at the front of black key inductor 22 all the time.As shown in Figure 2, displacement detector 15 in the double track inductor is fixed on the keying circuit plate 17 with displacement transducer 16, circuit board 17 is fixed on the circuit board aluminum frame 18, and displacement detector 15, displacement transducer 16, keying circuit plate 17 constitute key (Bai Jian 4, black key 3) inductor with circuit board aluminum frame 18.Please in conjunction with Fig. 1, shown in Figure 2, when the fulcrum that forms along black key wire nail 1 when black key 3 rotates and descends, the key displacement detector 15 that the decline of black key 3 promotes on the black key inductor 22 descends simultaneously, the speed that displacement detector 15 descends, angle are tested by the induction of displacement transducer 16, produce a electric signal by time, velocity variations, this electric signal is through a series of technical finesses, finally is reduced into the descend fender qin sound of fast jogging speed of reflection key.The principle of work of white key 4 is identical with black key 3.In addition, in black key, middle sleeper keying board slot 21 these positions, reality also can be incorporated in white key inductor 23 on the same circuit board with black key inductor 22, and its principle of work is also identical therewith.
