Finger force practice tray of musical instrument

Abstract

The invention discloses a finger force practice tray of a musical instrument. A pull rope is arranged at one side of a shell; more than five groups of finger slots are distributed in the shell by equal spacing; shiatsu plates are arranged in the finger slots; the sides, close to the shiatsu plates, of a bottom cover are connected to one end of an electric telescopic rod; a supporting plate is connected to the other end of the electric telescopic rod; a pressure sensor is arranged at the upper side of the supporting plate; a locating pillar is arranged at the side, close to the pressure sensor,of the supporting plate, a spring is arranged in the middle of the locating pillar; the side, away from the locating pillar, of the spring is connected to the shiatsu plates; through stretching of the electric telescopic rod, the supporting plate, which is connected, is pushed to move, and along with the moving of the supporting plate, the spring undergoes pressing stretching, so that pressing force can be adjusted in accordance with different human fingers; and through cooperation of sliding platforms and connecting bosses, which are arranged at two sides of the shiatsu plates, with a sliding shaft in use, the stability of the pressing force can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of teaching instruments, in particular to a musical instrument finger force practice disk. Background technique [0002] The connection between the player's fingering and fingering force is dependent on the instrument. When practicing fingering on the instrument, it is also accompanied by the use of fingering force. After leaving the instrument, you can no longer practice, which is not conducive to training. Therefore, a musical instrument is needed. For example, the patent application publication number 201520674173.1 discloses a musical instrument finger training disk, which includes an elastic main body disk. The surface of the main body disk is provided with ring-shaped first dikes and second dikes arranged sequentially from the inside to the outside. Second embankment and the third embankment, the central axis of the second embankment, the central axis of the third embankment all coincide with the centr...

When practicing fingering on the instrument, it is also accompanied by the use of fingering force. After leaving the instrument, you can no longer practice, which is not conducive to training. Therefore, a musical instrument is needed. For example, the patent application publication number 201520674173.1 discloses a musical instrument finger training disk, which includes an elastic main body disk. The surface of the main body disk is provided with ring-shaped first dikes and second dikes arranged sequentially from the inside to the outside. Second embankment and the third embankment, the central axis of the second embankment, the central axis of the third embankment all coincide with the central axis of the first embankment, the outer surface of the first embankment and the inner surface of the second embankment A ring-shaped middle ring groove is formed between them, but during the use of the above patents, the pressing force cannot be adjusted according to the different fingers of the human body, and the stability of the pressing force cannot be guaranteed.
