A kind of piano finger lifting trainer

Abstract

The invention relates to the field of piano auxiliary teaching, and provides a piano finger lifting trainer, comprising a finger button mechanism, a palm holder, a display part and a bracket part; the finger button mechanism includes five sets of analog buttons and a miniature pressure sensor, and the palm The holder includes a proximity switch, a shield, and a shield adjustment bush, the display component includes a display screen and a data processing board, and the bracket part includes a palm support, a lower arm of the display screen, and an upper arm of the display screen; the analog keys are in the form of a display screen and a data processing board. C-shaped, with a cantilever structure, the upper part is a cantilever beam, and the lower part is fixed on the palm support through a fixing hole. After heat treatment, the cantilever beam that simulates the button has a certain elasticity, and can automatically bounce after pressing down. The micro pressure sensor and connected to the data processing board. The training device of the invention adopts the standard spacing of piano keys, records the key strength and frequency information of the trainer in real time, and sends out an alarm when the palm of the hand is stressed, so as to correct the wrong hand shape of the trainer when practicing the piano in time.

Description

technical field [0001] The invention relates to the field of piano auxiliary teaching, in particular to a piano finger lifting trainer. Background technique [0002] Along with the raising of people's living standard, more and more people begin to learn piano. In piano practice, besides long hours of repertoire, basic finger exercises are particularly important, and how to maintain the correct hand shape is the most important thing for piano beginners to practice fingers. The hand shape in piano playing requires the five fingers to be separated, the palm to be arched, and the whole hand to be in a semicircular shape, and the fingers must be able to reach a certain speed and strength when playing the keys. Beginners often cannot do these points. [0003] There are very few trainers specially designed for piano finger training.

The hand shape in piano playing requires the five fingers to be separated, the palm to be arched, and the whole hand to be semicircular, and the fingers must be able to reach a certain speed and strength when playing the keys. Beginners often cannot achieve these points

[0003] There are very few trainers specially designed for piano finger training. The Chinese invention patent "A Piano Trainer (CN108389471 A)" discloses a piano trainer for training hand shape and finger strength. The piano practice device has the following deficiencies: the distance between the fingers is adjusted by adjusting the struts, and the training time of different people is different, which is not conducive to the habit of cultivating the distance between the fingers of the standard piano key; using an auxiliary ball to place the palm of the hand may easily cause the trainer's palm to support the fingers. habit, it is difficult to maintain the hand shape when playing in real life; more importantly, the exerciser has no counting and diagnostic functions, and the trainer cannot intuitively count information such as key strength and frequency, and it is difficult to correct and train wrong hand shapes quantitatively. The effect is greatly reduced

In addition, the device is realized through multiple mechanical transmissions, the structure is complex, and it is prone to failure during practice
