Detailed Description
As shown in fig. 1 to 9, a grand piano damper lever comprises a damper lever 1, a fulcrum 5 and a damper screw pedestal 6, wherein a plurality of through holes 2 are arranged in the damper lever 1, a balance weight damper lead 3 is arranged in at least one through hole 2, namely, the balance weight damper lead 3 is arranged in the through hole 2 or the balance weight damper lead 3 is not arranged, the damper lever 1 adjusts the balance through the position, the number or the weight of the balance weight damper lead 3 in the through hole 2, therefore, the structure is characterized in that the damper lever is used for balancing the damper lever, different positions, the number and the weight of the balance weight damper lead 3 can obtain different effects, and under the condition of not changing the key-down depth, the speed of a hammer for striking a string can be changed, the loudness of a piano can be changed, and the expressive force of a piano can be increased.
When there are three through holes in the damper lever 1, the three through holes correspond to the first weight damper lead B, the second weight damper lead C, and the third weight damper lead D, respectively. In fig. 2, the damper lever 1 has three weights of a first weight damper lead B, a second weight damper lead C and a third weight damper lead D, and the corresponding keys feel heavy and are distributed in a bass region; in fig. 3, two weights, i.e., a second weight damping lead C and a third weight damping lead D, are arranged, and the other through hole is through and is not provided with a weight damping lead; in fig. 4, two weights, namely a first weight damping lead B and a third weight damping lead D, are arranged, and the other through hole is communicated without the weight damping lead; in fig. 5, there are two weights, i.e., a first weight damping lead B and a second weight damping lead C, and the other through hole is through and no weight damping lead is placed; in fig. 6, there is a first weight damping lead B and one weight, and the other two through holes are through without the weight damping lead; in fig. 7, there is a second weight damping lead C with one weight, and the other two through holes are through without the weight damping lead; in fig. 8, there is a third weight damping lead D, one weight, and the other two through holes are through without the weight damping lead; in fig. 9, the damper lead is not provided with a weight, and the three through holes are through, which is an initial state in which the damper lead is not provided with a weight.
In the preferred scheme, the damping lever 1 is provided with the through hole 2 along the length direction, and the through hole is formed along the length direction, so that the counterweight lead block is convenient to place stably, and the balance is facilitated.
