Description

Piano playing finger touch trainer

technical field

The utility model relates to a training device, in particular to a finger-touch training device for piano playing, which belongs to the technical field of music.

Background technique

Learning to play the piano is not easy, and it is even more difficult to play the piano well. After years of teaching, it has been found that among many influencing factors, the strength of the fingertips touching the keyboard is the key. Proper control of the fingertips touching the keyboard during the process is the basis for improving the playing effect. Therefore, in the technical training stage, especially for children and teenagers who are new to the piano, they should first practice finger touch control, which can be used for further practicing piano playing. Lay a good foundation.

Contents of the invention

In order to solve the above-mentioned problems, the purpose of this utility model is to provide a kind of piano playing finger touch trainer, by arranging the pressure sensor on the original tone key on the simulated piano keyboard, the finger touches the keyboard force through digital-to-analog conversion and microprocessor processing. Displayed on the liquid crystal display, you can intuitively see the strength of each key, so that you can have a skilled fingertip control feeling through repeated practice, and lay a good foundation for better piano performance.

The technical solution adopted by the utility model to solve the technical problems is: a piano playing finger touch trainer, which is composed of a chassis, a bottom cover, a liquid crystal display, a microprocessor, an A/D converter, a clock circuit, a piano key, and a chromatic key , pressure sensor, power supply, polyurethane film, power switch. A liquid crystal display is fixed in the through hole on the top of the case. A microprocessor, an A/D converter, a clock circuit, and a power supply are fixed in the chassis, and the clock circuit and the liquid crystal display are connected to the microprocessor, and the power supply is connected to the microprocessor through a power switch. Fourteen piano key blocks and ten chromatic key blocks are fixed on the bottom of the case according to the arrangement order of the piano keyboard. Pressure sensors are fixed in the through holes at the front ends of each piano key block and chromatic key block, and the pressure sensors pass through the The A/D converter is connected to the microprocessor. The bottom surface of the chassis is connected with the bottom cover. The outer surfaces of the piano key blocks and the chromatic key blocks are connected with polyurethane films.

The beneficial effect of the utility model is that the structure is simple and easy to use, and the number of finger touches on the keyboard can be displayed intuitively. Through general practice and targeted practice, the effect can be quickly practiced, laying a good foundation for further practicing the piano. Base.
