Weighing body 50 (50W and 50B) is assemblied in the key framework 10 also related with white key 20 and black key 40 respectively.Can be thereby each weighing body 50W is supported by related bearing 51 with 50B around pivot 14 vertical rotation, this pivot 14 places on the weighing body support ribs 13 that is integrally formed at key framework 10.The almost total weight of each weighing body 50 (50W or 50B) all concentrates on the rearward end 52 (52W or 52B) of weighing body 50 (50W or 50B).
It is integrally formed with the anterior bottom of white key 20 to hang actuator 29, can extend downwards from here so that hang actuator 29.It is integrally formed with the anterior bottom of black key 40 to hang actuator 45, can extend downwards from here so that hang actuator 45.Hang actuator 29 and 45 and have the elastic component of making by rubber etc. that is fixed in its lower end, and hang actuator 29 and 45 separately lower ends as the direct drive part of related weighing body 50W of driving and 50B.When junction surface, bottom 53 was driven, weighing body 50 pivoted with associated key, thereby applied the suitable power of being used to realize and the similar sense of touch of sense of touch from the acoustic piano acquisition to key.
Upper limit retainer 83 protrudes from the last rear portion of key framework 10, and lower limit retainer 84 protrudes from the following rear portion of key framework 10.It is related with each key with lower limit retainer 84 that but fit on is placed restrictions on moving part 83, but in the present embodiment, and its common assembling is used for a plurality of keys (for example, in the equipment among all key or the key unit KU all keys).The rearward end 52 of weighing body 50 and lower limit retainer 84 adjacency define the no pressing position (initial position) of weighing body 50 and associated key thereof thus.On the other hand, rearward end of weighing body 50 52 and upper limit retainer 83 adjacency, what define weighing body 50 and associated key thereof thus pushes terminal position (pivotal end position).
In addition, key switch (key-on switch) 81 is assemblied on the substrate 80 that is positioned on the key framework 10, and is associated with each white key 20 and black key 40.Each described key switch 81 detects pushing of a related key.Generater of musical tone shows among the figure, based on the testing result generation musical sound of key switch 81.
In addition, the front portion of key framework 10 is formed with a plurality of key guide portion 12, and each key guide portion 12 is used to guide the associated key of operation when pushing.Key guide portion 12 forms related with each white key 20.Each white key 20 has the leading section 20a that is formed with the directed section (not shown), this directed section is used for and a related key guide portion 12 engages, thus transverse movement that engages the leading section 20a that has limited white key 20 between directed section and the key guide portion 12 and guide properly the suitable vertical movement of leading section 20a of white key 20.
Fig. 2 is the vertical view of key unit KU.Key unit KU comprises two white key unit KUW (KUW1 and KUW2) and a black key unit KUB.In Fig. 2, key unit KUB is represented by dotted lines.Fig. 3 is the side view of key unit KU latter half.
Though in the present embodiment, a key unit KU is that the unit forms with an octave as shown in Figure 2, is not limited only to this, is comprising that under the situation of a plurality of keys, key unit KU can be provided with separately.For example, the key more than two octave can be integrally formed at key unit KU.As shown in Figures 2 and 3, white key unit KUW comprises the first white key unit KUW1 and the second white key unit KUW2, in this first white key unit KUW1, being furnished with separately, white key 20 one of pitch name " D, F and A " are connected in base end part 21, in this second white key unit KUW2, being furnished with separately, white key 20 one of pitch name " C, E, G and B " are connected in base end part 21.Black key 40 one of pitch name " C#, D#, F#, G# and A# " are connected in base end part 41 and form black key unit KUB by being furnished with separately.
Each first white key unit KUW1 and the second white key unit KUW2 form by white key main body 23 is connected in related base end part 21 via vertical articulated section 24 separately and falling hinger 22 separately with the thin plate form.The vertical articulated section 24 that is connected in base end part 21 laterally is being easy to bending, thereby when being in free state, vertical articulated section 24 allows the free end of related white key main body 23 to swing along key orientation (laterally).This vertical articulated section 24 of the leading section 20a of the white key 20 of association, key guide portion 12 (referring to Fig. 1) and the directed section that does not show cooperatively interact with suitable correction because the offset of key main body 23 in vain in the key orientation that manufacturing mistake or loading error cause.
The falling hinger 22 that is connected in 24 front sides, vertical articulated section is easy to bending in vertical direction, thereby when being in free state, the free end that falling hinger 22 allows white key main body 23 along key push/release direction (vertical direction) is around base end part 21 and vertical articulated section 24 pivots.In addition, the last rear portion of white key main body 23 is formed with buffer part 25, and this buffer part 25 is used to avoid the related black key 40 with pivoting to disturb.
Fig. 4 is the stereographic map of the black key latter half observed from oblique lower angle.As shown in Figure 3 and Figure 4, black key unit KUB forms by a plurality of black key main bodys 43 are connected in base end part 41 via connecting portion 42.This connecting portion 42 comprises thick 42a and thin horizontally hinged 42b.More specifically, thick 42a rear end 43a along key orientation and backward directions from each black key main body 43 extends, and thick 42a is connected by horizontally hinged 42b with base end part 41.
As Fig. 2 (dotted line) and shown in Figure 4, black key main body 43 is furnished with horizontally hinged 42b respectively, and horizontally hinged 42b is formed on the position of horizontal space.More specifically, the part connecting portion 42 at thick 42a rear has empty horizontal interior section, and therefore horizontally hinged 42a has horizontal prong like.In addition, the overall width Wa along the key orientation of horizontally hinged 42b is set to larger than the width W b of related black key main body 43.
Thick 42a fully is thicker than horizontally hinged 42b, therefore hardly can be only by such as the power that gives by the key pressing operation bending.Be similar to falling hinger 22, the free end that horizontally hinged 42b allows related black key main body 43 basically along key push/release direction rotates around base end part 41.Strictly say, white key main body 23 is around the tie point PW of pivot between vertical articulated section 24 and falling hinger 22 of its pivot, and each black key main body 43 is around the pivot of its pivot tie point PB (referring to Fig. 3) between base end part 41 and horizontally hinged 42b.In addition, the longitudinal center of each falling hinger 22 and horizontally hinged 42b corresponds essentially to the center of the pivoting action of each white key main body 23 and black key main body 43.
Herein, because horizontally hinged 42b is wide hinge, so even under the situation that does not have the key operation guiding, the free end of black key main body 43 (front end) still is restricted along the swing of key orientation during key is pushed.In addition because horizontally hinged 42b has prong like (it has empty horizontal interior section), so even use wide hinge arrangement can prevent that also their hardness is too high, and provide and make black key main body 43 push the rotating good hinge function of direction along key.Therefore, can obtain to exempt the effect that key operation guides and guarantees hinge function in the lump.
As shown in Figure 3, the base end part 21 of base end part 21, the first white key unit KUW1 of the second white key unit KUW2, and the base end part 41 of black key unit KUB under stack gradually and assemble mutually to form common-base end 30. Base end part 21,21 and 41 is formed with a plurality of screw fastener holes 26,26 and 44 that pass wherein separately.The bottom of the base end part 21 of the second white key unit KUW2 also is the bottom of common-base end 30, is formed with the surface of contact 27,28 that becomes with it in the face of relation, and surface of contact 27,28 is positioned at fore-and-aft direction with respect to described bottom.
In addition, as shown in Figure 3, the fixed part 15 that is fixed with common-base end 30 thereon with 16 respectively with the mode related with surface of contact 27 and 28 be formed on the top of key framework 10, to a little backward each position longitudinally, the center of key framework 10.Fixed part 15 and 16 forms by each front/rear end from key framework 10 part protruding upward.In the center section of key framework 10 between fixed part 15 and 16, be formed with a plurality of screw holes 17 in the vertical corresponding to each screw fastener hole 26 and 44.
By contacting with 16 with fixed part 15 respectively with 28 with the surface of contact 27 of relative mutually relation with common-base end 30, and screw 82 (referring to Fig. 1) is screwed into separately screw hole 17 via the screw fastener hole 26 and 44 of each auto correlation of common-base end 30, with common-base end 30 secure in key framework 10.Thereby white key 20 and black key 40 are placed and can play the state that operation pivots.Should be noted that fixedly the mode of common-base end 30 is not only for therewith.
In integrally formed key unit KU, horizontally hinged 42b of each black key 40 is positioned at the rear of the falling hinger 22 of related white key 20.Therefore, tie point PB also is positioned at the rear of tie point PW.This will make as the distance maximization between the base end part 41 of black key 40 pivots (tie point PB more accurately says so) and its free end, strengthen the operability of black key 40 in performance thus.
In addition, horizontally hinged 42b of the vertical articulated section 24 of each white key 20 and related black key 40 is arranged in roughly same lengthwise position, and in other words, vertical articulated section 24 just in time is positioned under horizontally hinged the 42b basically.Say that strictly vertical articulated section 24 is in horizontally hinged 42 front end 42b1 and the longitudinal extent between the 42b2 of rear end.In brief, by the space that effectively utilizes horizontally hinged 42b below vertical articulated section 24 is set.
In addition, vertical articulated section 24 has the upper surface, this upper surface is as forming (referring to Fig. 3) to the inclined-plane of front lower place slight inclination, with the interference between the vertical articulated section 24 of horizontally hinged 42b avoiding at black key 40 during the downward pivoting action of black key 40 and Bai Jian 20.
According to present embodiment,, increase so can guarantee the radius of gyration of the main operation part of black key 40 easily because horizontally hinged 42b of black key 40 is positioned at the rear of the falling hinger 22 of related white key 20.Thereby enough button strokes of easier acquisition black key 40, and make sense of touch be lighter than prior art.Can improve the operability of black key 40 in performance like this.In addition because the vertical articulated section 24 of white key 20 and horizontally hinged 42b of black key 40 are arranged in roughly same lengthwise position, and vertical articulated section 24 is in horizontally hinged 42 front end 42b1 and the longitudinal extent between the 42b2 of rear end, so when vertical articulated section 23 is set, can effectively utilize side space under horizontally hinged the 42b between falling hinger 22 and the base end part 21, thereby adapt to of the skew of the white key main body 23 of white key 20 along the key orientation.
Though shown the key unit KU that is formed with a plurality of keys in the present embodiment, be example only, be not limited only to this, the base end part that can adopt each independent keys is in identical lengthwise position alignment and the structure that supported by key framework 10.
