When soundboard group 30G was installed to resonant tank 50, the soundboard that at first uses connecting line 44 will form soundboard group 30G gathered together.For example, series arrangement soundboard 30 with pitch, connecting line 44 is inserted the supported hole 36 of soundboard 30, in 37 (in example shown in Figure 8, connecting line 44 forms a circle in the counterclockwise direction from the lower-left side of soundboard 30), therefore, the two ends of connecting line 44 all are positioned at the left side of soundboard 30, in minimum pitch side.
More specifically, according to the order of pitch, from the preceding supported hole 36 of the soundboard 30 that is used for minimum pitch, connecting line 44 is the preceding supported hole 36 of break-through soundboard 30 sequentially.Be used for the preceding supported hole 36 of the high soundboard of descant 30 in break-through after, according to the order of pitch, from being used for the back supported hole 37 of the high soundboard of descant 30, connecting line 44 is the back supported hole 37 of break-through soundboard 30 sequentially.At last, the position in soundboard 30 left sides that are used for minimum pitch links together the two ends of connecting line 44.In any position, the two ends of connecting line 44 can be joined together.Can use two or many lines, these lines are joined together to form wall scroll connecting line 44.
Shown in Fig. 7 and 8, resonant tank 50 has front side and the shared wooden wall 51,52 of rear side, the whole length of its basic extend through resonant tank 50 on the direction of arrange-key.Distance between front side and the rear side common wall 51,52 becomes bigger towards low range one side of resonant tank 50.Therefore, above resonant tank and direction from left to right, these common walls 51,52 are arranged as inverted V-shaped.In front side and the rear side common wall 51,52 each is formed with the pilot hole (not shown) in its lower surface, the pin 41 of securing member 40 can easily be assemblied in this pilot hole.
The soundboard group 30G that will form in order to use connecting line 44 that soundboard 30 is linked together is installed on the resonant tank 50, for example, resonant tank 50 is inverted, the pin 41 of securing member 40 is inserted in the pilot hole of the front side of resonant tank 50 and rear side common wall 51,52, uses then such as the instrument of hammer pin 41 to be pressed in the pilot hole securing member 40.Carry out above-mentioned operation for all securing members.Then, soundboard group 30G is placed on the lower surface of the front side of resonant tank 50 and rear side common wall 51,52, and the position between a plurality of soundboards 30 engages connecting line 44 with the line receiving unit 43 of securing member 40., inverted resonant tank 50 be inverted to normal condition, hung maintenance thereby soundboard group 30G is installed with the resonant tank 50 of connecting line 44, shown in Fig. 3 and 6 thereafter.Thus, constitute generater of musical tone unit UNT, wherein resonant tank 50 and all soundboards 30 are formed in the unit.
In generater of musical tone unit UNT, the antinode part 31 of soundboard 30 is arranged on the position of the opening that forms in (downside) corresponding resonator near a plurality of resonators (back will be mentioned) of resonant tank 50, thereby can vibrate independently of one another.Distance between the adjacent soundboard 30 is temporarily determined by the thickness of corresponding fasteners 40, places the pin 41 of securing member 40 can easily aim at pilot hole, this just feasible operation that is easy to carry out requirement.As shown in Figure 8, soundboard group 30G is divided into two groups on the direction of arrange-key.For in described left group and the right group each, can form at least one pair of front and rear pilot hole, thereby when being installed to soundboard 30 on the resonant tank 50, can automatically determine distance between the adjacent soundboard 30 by the thickness of relevant securing member.But it is not indispensable being pre-formed pilot hole.
As shown in Figure 6, resonant tank 50 is made up of low range part 50A, midrange part 50B and the high range part 50C that type differs from one another.The low range part 50A of resonant tank 50 is Helmholtz's type resonant tanks, and resonator RM1 wherein is set, and the quantity of resonator RM1 is identical with the quantity of the soundboard that is associated 30, with corresponding with these soundboards 30.Midrange part 50B is a stopped pipe type resonant tank, the quantity resonator RM2 identical with the quantity of the soundboard 30 that is associated wherein is set, with corresponding with these soundboards 30.Resonator RM1 and RM2 are called as predetermined resonator.High range part 50C is the monotype resonant tank with single resonator RM3, and its soundboard 30 that is associated is shared.
As shown in Figure 7, by a plurality of dividing plates (first plate member) 53 with different length, the front side of resonant tank 50 and rear side common wall 51,52 are connected to each other.Dividing plate 53 is made by the flat board that extends parallel to each other, and it extends on vertical with the vertical direction of the resonator of resonant tank 50, as shown in Figure 6, extends to its upper end from the lower openings of each resonator.At the front and rear of dividing plate 53, use bonding agent etc., dividing plate 53 is fixed to front side and rear side common wall 51,52.
As shown in Figure 7, at each range part 50A, among 50B and the 50C, between each adjacent dividing plate 53, two soundboards 30 of configuration on the direction that key is arranged.Distance between the adjacent separator 53 is a bit larger tham the overall width of corresponding two soundboards 30.In low range part 50A and midrange part 50B, by swash plate (second plate member) 54 and 55, adjacent dividing plate 53 is connected to each other.Between two adjacent dividing plates 53, there are two resonator RM1 that form by swash plate 54, and two the resonator RM2 (with reference to figure 6) that form by swash plate 55.Therefore, dividing plate 53 together forms " chamber-qualifying part " with swash plate 54,55.
As shown in Figure 6, the low shared cover 56 of range part 50A is fixed to the upper end of the dividing plate 53 that is used for low range part 50A, thus the top of closed all resonator RM1 together.In midrange part 50B, there is the cover 57 that is used for two resonator RM2, it is fixed to the upper end of dividing plate 53, thus the top of closed resonator RM2.In addition, a shared cover 58 of high range part 50C is fixed to the upper end of the partition member 53 that is used for high range part 50C, thus the top of closed resonator RM3.
Each swash plate 54,55 is all formed by the flat board that extends on the vertical direction of resonant tank 50.Swash plate 54 extends parallel to each other, and swash plate 55 also extends parallel to each other.Therefore because swash plate 54,55 is basic identical on structure and function each other, swash plate 55 among the midrange part 50B and the structure of resonator RM2 will be described mainly below.
Figure 10 is the partial enlarged drawing of the midrange part 50B of the generater of musical tone unit UNT shown in the presentation graphs 7.Here as representational example, two resonator RM2 are described, and in order to distinguish, back mark 1 is added on each resonator RM2, corresponding dividing plate 53 and the corresponding soundboard 30, then marks 2 and is added on each another resonator RM2, corresponding dividing plate 53 and the corresponding soundboard 30.Use cement etc., the two ends that connect the swash plate 55 of two dividing plate 53-1,53-2 are respectively fixed to the part of dividing plate 53-1 and the part of dividing plate 53-2, wherein when when the vertical direction of these plates is seen, this part of described dividing plate 53-1 is in the position of still close its rear end, centre of dividing plate 53-1, and this part of described dividing plate 53-2 is in the position of still close its front end in the centre of dividing plate 53-2.
In generater of musical tone unit UNT, the centre position of each hammer felt 24 (with reference to figure 2) is consistent with the antinode center 31P (with reference to figure 5A and 5B) of corresponding soundboard 30.On vertical direction, the position of the antinode center 31P of all soundboards 30 is identical, thereby in vertical view, the straight line L1 of the hypothesis shown in Figure 10 is by all antinode center 31P.In vertical view, straight line L1 also passes through all resonator RM1, RM2, and the zone of RM3.
As shown in figure 10, soundboard 30-1,30-2 are arranged between dividing plate 53-1, the 53-2.In the space that between dividing plate 53-1 and 53-2, limits, correspond respectively to resonator RM2-1 and RM2-2 with respect to the front side and the front and rear on the rear side of swash plate 55.As seeing in vertical view, the antinode center 31P of soundboard 30-1 is included among the resonator RM2-1, and the antinode center 31P of soundboard 30-2 is included among the resonator RM2-2.Therefore, the musical sound that produces by soundboard 30-1 and 30-2 respectively with the sympathetic response among resonator RM2-1 and the RM2-2 one to one of these two soundboards.By this way, each all is arranged in corresponding resonator RM among the antinode center 31P of all soundboards 30.
Normally, if width is too little, then each resonator of resonant tank just can not be realized gratifying sympathetic response effect.Each the resonator RM2-1 and the RM2-2 that guarantee this embodiment have enough width on the direction that key is arranged, thereby can realize gratifying sympathetic response.In addition, the soundboard 30 that quantity is identical with key 27 and 28 is arranged in the width identical with the overall width of key on the direction that these keys are arranged, and the overall width of two soundboards 30 enough disposes two resonator RM2.Therefore, be different from prior art, movement device 20 and soundboard 30 needn't be divided into and be used for the two-stage structure of the keyboard KB of structure usually, and can be configured to the one-part form structure.
Although because two range part 50A, the soundboard width difference between the 50B, the angle of inclination of swash plate 54,55 different with length (with reference to figure 7), the interior swash plate 54 of low range part 50A have with midrange part 50B in swash plate 55 essentially identical structures.Shown in Fig. 6 and 7, configured port forms parts 60 in the bottom of each the resonator RM1 that hangs down range part 50A.At the opening part of each resonator RM1 (except the resonator RM1 of left end), by two dividing plates 53, swash plate 54, and port forms parts 60 formation ports.In Helmholtz's type resonant tank, the pitch that the musical sound of sympathetic response therein has is subjected to the influence of the volume of the length of port and cross-sectional area and resonant tank usually.For example, the pitch of musical sound sympathetic response in resonant tank is along with the reduction of the increase of port length and port cross-sectional area and reduce, even also is like this when the volume of resonant tank remains unchanged.In the present embodiment, port forms parts 60 and forms the shape of suitably determining, with the length and the cross-sectional area of the port of regulating each resonator RM1, thereby make that the musical sound with pitch of being determined by corresponding soundboard 30 can sympathetic response in resonator satisfactorily.
According to present embodiment, each that belongs in the soundboard 30 that hangs down range part 50A is provided with first and second mass concentrating portions 32,33 in its part with respect to supported hole 36,37 more close front-end and back-end, and the first and second thinner parts 34,35 of between the antinode part 31 and first and second mass concentrating portions 32,33, extending respectively, and make (with reference to figure 5A and 5B) by homogenous material.This just makes and is easy to shorten the total length of soundboard 30 and reduces its width, thereby improves the degree of freedom of design.Therefore, keyboard instrument can miniaturization, contains wide range simultaneously.Owing to there is this general trend, promptly be used to produce the soundboard of musical sound, become bigger in particular for the length that produces the soundboard that hangs down the pitch musical sound, so the soundboard shown in Fig. 5 A and the 5B 30 is suitable for producing the musical sound of low pitch.
Can easily make soundboard 30 by removing from a direction without the part of the parts 38 of machining, wherein said part is positioned at the side without the parts of machining on the direction of thickness, be that xsect is the elongated member of rectangle and is made by homogenous material without the parts 38 of machining wherein.Therefore, be easy to make the soundboard 30 that soundboard 30 and making is used to produce different pitches and have identical width.In generater of musical tone unit UNT, the quantity of the type of soundboard width can be reduced to three.
And, according to present embodiment, in a plurality of soundboards 30 each all can be installed on the resonant tank 50 quiveringly in the position near the opening of the corresponding resonator of resonant tank 50, thereby resonant tank 50 and soundboard 30 are incorporated among the generater of musical tone unit UNT.Therefore, be easy to replace generater of musical tone unit UNT, wherein between resonant tank 50 and soundboard 30, keep suitable position relation with new generater of musical tone unit.For example, replace with new generater of musical tone unit textural inequality, in the acoustics tone plate percussion instrument, also can easily change tone color even if make at soundboard and/or resonant tank.In addition, the feasible maintenance that is easy to realize soundboard group 30G and/or resonant tank 50 of this easy replacement of generater of musical tone unit UNT.
And, can keep a plurality of soundboards 30 quiveringly together by connecting line 44, and connecting line 44 is installed on the resonant tank 50 by a plurality of securing members 40.Especially, make soundboard and make it thicker in the position that forms vibration nodal point, this just make can in soundboard 30, form not extension in vertical direction but in the side of arrange-key upwardly extending supported hole 36,37.Because supported hole 36,37 extends on the direction of arrange-key, therefore the soundboard 30 that can use connecting line 44 will constitute soundboard group 30G remains on together from the state that resonant tank 50 hangs.This just makes it possible to handle together soundboard group 30G and together soundboard group 30G is installed on the resonant tank 50 and from resonant tank 50 removes soundboard group 30G, to be easy to install and replace soundboard 30.Because supported hole 36 and 37 forms in soundboard 30 in the position that forms vibration nodal point, so these holes do not hinder soundboard to realize gratifying pronunciation.
When soundboard 30 was installed, the distance between the adjacent soundboard 30 was temporarily determined by securing member 40.This is easier installation and replacement soundboard 30 just.
As long as can keep a plurality of soundboards together, just needn't form supported hole 36,37 with the form of through hole by line parts such as connecting line 44.For example, each of these supported holes can be this groove, and its xsect forms part-circular and opens to the lower surface of soundboard 30.From realizing keeping together the view of function of a plurality of soundboards, the line of use not necessarily is restricted to connecting line 44.Should be noted that not necessarily to keep all soundboards together, but soundboard group 30G can be divided into two or more groups, and each of separated soundboard group can be held togather.
According to present embodiment, each of resonator RM1, RM2 of guaranteeing to be used for low range part 50A and midrange part 50B has enough width on the direction of arrange-key, it equals the overall width of corresponding two soundboards 30 or wideer than the overall width of corresponding two soundboards 30, thereby may realize gratifying sympathetic response.In addition, limit resonator RM1, RM2,, thereby resonant tank 50 can be configured to have the length of shortening on the direction of arrange-key in front elevation, guarantee the suitable width of each resonator simultaneously so that it overlaps each other.Therefore, the soundboard group 30G of whole keyboard instrument and resonant tank 50 can be constructed to the one-part form structure.
The structure keyboard instrument is so that imaginary straight line L1 passes all resonator RM1, RM2 and RM3, and when from keyboard instrument preceding to after direction when seeing, the antinode center 31P (referring to Fig. 5 A and 5B) of all soundboards 30 is positioned on the identical position, thereby can unify the operation sense between all soundboards 30, and make soundboard group 30G compact dimensions on the longitudinal direction of soundboard 30.
Resonator RM1, RM2 are limited by a plurality of dividing plates 53 and swash plate 54,55, front side and rear side common wall 51,52 are connected by dividing plate 53, adjacent dividing plate 53 connects by swash plate 54,55, thereby these resonators can be restricted to simple structure and can easily make, and this particularly extends parallel to each other owing to a plurality of dividing plates 53.
And, be different from traditional two sections structure, in the present embodiment, the soundboard group 30G and the resonant tank 50 of whole keyboard instrument can have the one-part form structure, and do not need to be used for the key pressing operation is delivered to the connecting link of the length of the lower set of hitting the unit.The one-part form structure is textural simple and be easy to make to such an extent that weight is lighter.Identical on the upright position with soundboard 30 corresponding to black key 28 corresponding to the soundboard 30 of white key 27, this just makes and is easy to balance from the sound corresponding to the soundboard of white key and black key.And, be different from the two sections structure, can be from the sound of soundboard 30 outputs by bottom soundboard group, bottom strike unit group and the interference of bottom resonant tank.Therefore, can make the musical instrument simple structure, light weight and the operation sense of key can easily be unified and export the balance good sound effectively.In addition, in keyseat 14, form voice output port 14a, so soundboard 30 can directly output to sound the outside, thereby improve the efficient of voice output movement device 20 times.
Below, the second embodiment of the present invention will be described.Second embodiment compares with first embodiment, and it is identical in others still in the textural difference of the resonant tank 50 of generater of musical tone unit UNT.Figure 11 is similar to Figure 10, and it is according to present embodiment, and expression comprises the partial enlarged drawing of the midrange part of the resonant tank in the keyboard-type tone plate percussion instrument of resonant tank.
