Piano electronic teaching device based on DSP (digital signal processor)

Abstract

The invention relates to a piano electronic teaching device based on a DSP (digital signal processor), which relates to a music teaching aid. The piano electronic teaching device comprises a piano main body and a microcomputer control system; the piano main body has the structure of an ordinary piano, a piano baffle of the shell of the piano main body is also provided with a DSP control box, a touch screen, a USB (universal serial bus) 2.0 interface, a serial port female and a mode selector switch; and the microcomputer control system comprises a DSP control module, a power supply control module, a music transmission module, a detection alarming module and a touch screen human-machine interaction module, all modules of the microcomputer control system are integrated inside the DSP control box, the device has a teaching mode and a self-determined practice mode, so that the defects of high cost and inconvenience of the one-to-one and face-to-face teaching and the remote teaching can be overcome.

Description

technical field [0001] The technical scheme of the present invention relates to music teaching aids, specifically a DSP-based piano electronic teaching device. Background technique [0002] The piano is known as the king of musical instruments because of its wide range, rich expressiveness and excellent solo effect. It plays an irreplaceable role in modern music education and music creation. [0003] However, as far as piano teaching is concerned, one-to-one face-to-face teaching is still mostly used at home and abroad, but this teaching method is not only costly, but also often brings a lot of inconvenience to piano learners. CN 101145288A discloses a kind of electronic piano teaching system, is a kind of distance teaching system, can bring certain convenience to piano learner, but its technique is complicated, and cost is too high; CN 1218294C discloses a kind of automatic playing system of piano, But it does not have the function of piano electronic teaching.
