Abstract
The invention discloses a piano string striking device which comprises a key, a supporting plate, a connecting rod assembly, an auxiliary supporting block, an auxiliary striking hammer, a spring and a striking hammer, wherein a fulcrum part of the key is rotatably connected with a piano body through a rotating shaft, one end of the supporting plate is rotatably connected with the piano body through the rotating shaft, the other end of the supporting plate is in surface contact with the upper surface of one end of the key, the upper end surface of the supporting plate is rotatably connected with the lower end of the connecting rod assembly, the middle part of the connecting rod assembly is rotatably connected with the piano body of the piano, the auxiliary supporting block is fixedly arranged on one side of the middle section of the connecting rod assembly, the auxiliary striking hammer is arranged on one side of the upper end surface of the supporting plate, the auxiliary striking hammer is close to the auxiliary supporting block. Compared with the prior art, the auxiliary supporting block designed by the invention can assist force application, and meanwhile, the negative weight block is arranged to increase the force of striking string, so that a larger volume can be popped up without great force application of fingers, and the auxiliary supporting block has popularization and application values.
Description
Technical Field
The invention relates to an internal component of a piano, in particular to a piano string striking device.
Background
A piano is a keyboard instrument, and hammers are pulled with keys to strike strings. Since the end of the eighteenth century, pianos have been the most important home keyboard musical instruments in europe and the united states. Pianos originated from a modern piano-like keyboard instrument invented by cristofriedri, italian, in europe, early eighteen centuries, and have been in history for over three hundred years. In the prior art, the action of the string striker of the piano is generally directly pushed by a connecting rod, the force application requirement of the pile of fingers is higher, and therefore, the improvement space exists.
Disclosure of Invention
It is an object of the present invention to provide a piano action in order to solve the above problems.
The invention realizes the purpose through the following technical scheme:
the piano keyboard comprises a key, a supporting plate, a connecting rod assembly, an auxiliary supporting block, an auxiliary hammer, a spring and a string hammer, wherein a supporting point part of the key is rotatably connected with a piano body of the piano through a rotating shaft, one end of the supporting plate is rotatably connected with the piano body of the piano through the rotating shaft, the other end of the supporting plate is in surface contact with the upper surface of one end of the key, the upper end surface of the supporting plate is rotatably connected with the lower end of the connecting rod assembly, the middle part of the connecting rod assembly is rotatably connected with the piano body of the piano, the auxiliary supporting block is fixedly arranged on one side of the middle section of the connecting rod assembly, the auxiliary hammer is arranged on one side of the upper end surface of the supporting plate, the auxiliary hammer is close to the auxiliary supporting block, the spring is arranged between the connecting rod assembly and.
Preferably, the upper section of the connecting rod assembly is fixedly provided with a negative weight.
The invention has the beneficial effects that:
compared with the prior art, the piano string striker has the advantages that the auxiliary supporting block designed by the invention can assist force application, and meanwhile, the negative weight block is arranged to increase the force of striking the string, so that a larger volume can be ejected without great force application of fingers, and the piano string striker has popularization and application values.
Drawings
Fig. 1 is a schematic structural view of the present invention.
In the figure: 1-key, 2-bracing plate, 3-connecting rod assembly, 4-auxiliary supporting block, 5-auxiliary hammer, 6-spring, 7-hammer and 8-negative weight.
Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in fig. 1: the piano key comprises a key 1, a supporting plate 2, a connecting rod assembly 3, an auxiliary supporting block 4, an auxiliary hammer 5, a spring 6 and a hammer 7, wherein a fulcrum part of the key is rotatably connected with a piano body through a rotating shaft, one end of the supporting plate is rotatably connected with the piano body through a rotating shaft, the other end of the supporting plate is in surface contact with the upper surface of one end of the key, the upper end surface of the supporting plate is rotatably connected with the lower end of the connecting rod assembly, the middle part of the connecting rod assembly is rotatably connected with the piano body of the piano, the auxiliary supporting block is fixedly arranged on one side of the middle section of the connecting rod assembly, the auxiliary hammer is arranged on one side of the upper end surface of the supporting plate, the auxiliary hammer is close to the auxiliary supporting block, the spring is arranged between the connecting rod assembly and the auxiliary hammer, and the hammer is.
Preferably, the upper section of the connecting rod assembly is fixedly provided with a negative weight 8.
The working principle of the invention is as follows: when the auxiliary string hammer works, the keys are pressed down, the end parts of the keys jack the supporting plates, the supporting plates jack the connecting rod assemblies to be lifted upwards, meanwhile, the auxiliary string hammer strikes the auxiliary supporting blocks, the string hammer moves forwards, strings are struck, and the negative weight blocks are added to improve the force of striking the string hammer.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
Claims (2)
