A device for practicing piano playing finger force

Abstract

The invention discloses a piano playing finger strength training device, which comprises a transparent box, the upper wall of which is provided with a scale along its length direction, and the scale is composed of a plurality of scale lines, and each scale line is provided with a The transparent box does not contain the right side wall; the key is hinged on the edge of the upper wall of the opening of the transparent box through a hinge, and the lower left end is provided with a hitting plate; the supporting wall is fixed on the edge of the lower wall of the opening of the transparent box; the support The plate is arranged horizontally directly below the keys; the electromagnet is arranged on the right side of the support wall; the sphere is made of iron and is located inside the transparent box; the striker is inserted into the through groove. The present invention uses the striking plate under the keyboard to hit the ball, so that the ball moves, and the trainer can see the distance between the stop position of the ball and the position of the hitting device through the transparent box, and can intuitively It reflects the difference between the finger force pressed by the trainer this time and the standard finger force.

Description

technical field [0001] The invention relates to the field of piano practice auxiliary equipment, in particular to a piano playing finger force practice device. Background technique [0002] When practicing the piano, what we often need to practice is the finger force when playing. When hitting the keys, the difference in finger force directly leads to the difference in the sound played, and these are often It requires the trainer to carry out a lot of training on the piano, so as to produce the feel when playing. At present, there are some practice devices with finger force on the market, all of which are to set pressure sensors on the keys, and use the pressure sensors to detect the strength of the trainer pressing the keys, and compare the strength with the standard strength. I know whether the finger force for pressing the keys is too large or too small compared to the standard finger force, but it is difficult for the trainer to intuitively feel the difference between t...

At present, there are some practice devices with finger force on the market, all of which are to set pressure sensors on the keys, and use the pressure sensors to detect the strength of the trainer pressing the keys, and compare the strength with the standard strength. I know whether the finger force for pressing the keys is too large or too small compared to the standard finger force, but it is difficult for the trainer to intuitively feel the difference between the finger force that he is pressing this time and the standard finger force, so that he can When practicing again, it is difficult to accurately apply the force of finger pressing
