Multimedia educational piano

Abstract

The multimedia teaching instrument incldues microprocessor, keyboard, time-delay regulation key, power supply processing module and analog switch, etc, in which the analog signal of volume regulation key and time-delay regulatino key is passed through A / D converter, and converted into digital signal, then said digital signal, pedal key digital signal and keyboard detection and force sensor signal are fed into microprocessor. The microprocessor makes the key detection signal undergo the key code selection and decision treatment, and selects current key code from key code table, then makes the force sensor signal undergo the proportional-derivatives treatment, and selects key dynamic code from dynamic fuzzy table, then makes them undergo the fusion treatment to obtain standard frame code, and feeds it into interface and implements information interaction with computer. Said invented teaching instrument possesses tone, touch feed and dynamic key effect of quasi-piano. By utilizing computer software it can implement various tones, volumes and music creation, etc.

Description

Technical field: [0001] The invention relates to a multimedia teaching piano, which belongs to the technical field of music education. Background technique: [0002] At present, similar products on the market that can be used for piano teaching include electronic pianos and MIDI pianos, but most of them have unilateral functions. Among them, electronic pianos and MIDI pianos are relatively advanced electronic pianos that simulate the sound of pianos. Their characteristics are as follows: quasi-piano You can select and adjust the tone and various accompaniments. Some advanced electronic pianos have force keys, but ordinary electronic pianos and MIDI pianos have many shortcomings. Multimedia interactive teaching, the texture of the keys cannot be compared with that of the piano, there is no force detection of the keys, and the detection of the posture of the playing hand cannot be realized, etc. Contents of the invention [0003] The purpose of the present invention is to d...
