Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 4:
A kind of electronic piano keyboard mechanism of simulating conventional acoustic piano feel described in the utility model embodiment, include key support 1, Bai Jian 2 and black key 3, described white key 2 and black key 3 are arranged on key support 1, and one end and key support 1 are rotationally connected, the other end can under by and automatically reset.The below of described white key 2 and black key 3 is equipped with weight arm 4 one to one, be arranged on key support 1 described weight arm 4 seesaw-type, its one end bends extension downwards backward, and end is provided with heavy hammer part 41, the other end is provided with hard boss 42, and withstand the bottom of corresponding white key 2 or black key 3, concrete structure can be: one end of described weight arm 4 bends the rear end extending to key support 1 backward downwards, the hard boss 42 of the other end withstands the bottom in corresponding white key 2 or black key 3 centre position, and heavy hammer part 41 and hard boss 42 and weight arm 4 integrated injection molding, the cross section of described hard boss 42 is triangular in shape, and top is provided with towards side, soft clicking section 51 and stirs platform 421, the upper surface of described soft clicking section 51 is also provided with soft resilience part 52, and described soft resilience part 52 is one-body molded with soft clicking section 51, and the white key 2 at its end and soft rubber cushion 5 place or black key 3 are touched and be connected, described platform 421 of stirring is downward sloping platforms, and its end is provided with convex slope 422.
Further; Angle between the extended line that the line of the center of gravity M of described heavy hammer part 41 and the rotating fulcrum O of weight arm 4 and described hard boss 42 withstand the line of the fulcrum N of Bai Jian 2 or black key 3 and the rotating fulcrum O of weight arm 4 is 30 ° to 80 °.The bottom of described white key 2 and black key 3 is provided with soft rubber cushion 5 by the position that hard boss 42 withstands, described soft rubber cushion 5 backwards one end is provided with the soft clicking section 51 of inclined downward backward, described soft clicking section 51 is cylindricality flexible glue bodies, one-body molded with soft rubber cushion 5.
The principle of work of electronic piano keyboard mechanism described in the utility model is: press process in early stage at white key 2 and black key 3, between described hard boss 42 with soft rubber cushion 5, sliding contact is connected, press late stage at white key 2 and black key 3, extrude between described hard boss 42 with soft clicking section 51, stir and contact and connect (namely soft clicking section 51 with stir between platform 421 extrude, stir to contact connect), be specially: when white key 2 or black key 3 are pressed the initial stage, white key 2 or black key 3 are pressed onto fulcrum N, the weight arm 4 activity supporting point O that rotates is rotated, now the main source of white key 2 or the loading of black key 3 feel is exactly the reacting force of weight arm 4 dialogue key 2 or black key 3, be exactly heavy hammer part 41 specifically through the reacting force upwards of weight arm 4 at fulcrum N dialogue key 2 or black key 3, according to lever principle, after feel loading reaches a stationary value, just no longer rise, when white key 2 or black key 3 are pressed the later stage, soft clicking section 51 and the Contact stirring platform 421, the power that one is withstood soft clicking section 51 is produced when weight arm 4 is by stirring platform 421 and contacting with soft clicking section 51, thus produce skyrocketing of the loading of white key 2 or black key 3, then along with the continuation campaign of weight arm 4, soft clicking section 51 produces compression deformation, and produce slip because existence between two surface of contact is beneficial to the angle of weight arm 4 slip, and the flexural deformation of consequent soft clicking section 51, then stir platform 421 can slip over soft clicking section 51(namely when soft clicking section 51 just encounter stir platform 421 time, along with white key 2 or black key 3 continue press down, soft clicking section 51 is slided stirring on platform 421, until touch with convex slope 422, be obstructed, convex slope 422 is crossed in distortion, the soft resilience part 52 of this process also deforms.), thus the power release will originally withstood rapidly, produce suddenly falling of the loading of key; Whole change of pressing key (Bai Jian 2 or black key 3) process feel loading as Fig. 3, wherein X be key by down stroke, Y is feel loading.
Like this, by electronic piano keyboard mechanism of the present invention can realistic simulation conventional acoustic piano (particularly Horizontal piano) have have a bit jammed sensation at release sense early period of origination, achieve at key initial from being pressed simultaneously, loading arrives a stability number, before occurring to release sense, loading is no longer risen; After having crossed that section of release sense, before feel loading suddenly can be down to and be occurred close to release sense, thus more close with the feel of conventional acoustic piano, and can not to produce in key rise process at certain a bit by the sensation blocked; And structure is simple, be easy to processing, most economical, the most reliable.
In addition, the upper surface of described soft clicking section 51 is also provided with soft resilience part 52, and described soft resilience part 52 is strip flexible glue bodies, one-body molded with soft clicking section 51, and the white key 2 at its end and soft rubber cushion 5 place or black key 3 are touched and be connected.Like this, the reply effect of soft clicking section 51 can being ensured, ensureing that pressing Bai Jian 2 still can contact with stirring platform 421 with black key 3, realistic simulation conventional acoustic feel that piano has, stable work in work, reliably next time.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
