An intelligent acoustic piano

Abstract

The invention discloses an intelligent acoustics piano, having a piano learning-assisting function and a mute function. The piano comprises a main control board, wherein the main control board is provided with an MCU and a memorizer, a clock device, an input output interface and a sound card connected to the MCU; two ends of a sensor are respectively connected to a key and the main control board; and a key-pressing device, a display screen and a speaker are all connected to the main control board. A mute structure comprises a mute control device, a mute brake pedal and a damper steel wire rope that are connected by order, wherein the damper steel wire rope is connected with a damper connecting rod, the upper end of the damper connecting rod is provided with a mute damper to prevent a hammer from striking a string, and the lower end of the damper connecting rod is pivoted on the lower end of a braking steel wire shaft sleeve plate. The piano realizes a flexible teaching method of combining video with audio. Equipped with a professional music score system and an MIDI music score synchronizing system, the piano supports real-time score displaying and score progress displaying. Practicing piano playing with the mute function of the intelligent acoustics piano, the players can get better practice effect.

Description

technical field [0001] The invention relates to an acoustic piano, in particular to an intelligent acoustic piano which has the functions of mute and auxiliary playing learning, and supports the combined learning mode of video and audio. Background technique [0002] Learning to play the piano has its particularity, requires a certain amount of talent, and is inseparable from the teacher's face-to-face guidance. Currently, the auxiliary education methods for traditional musical instruments are very limited. At present, it mainly relies on the teacher's face-to-face teaching. When practicing on your own, you will face great difficulties. At present, there are some auxiliary devices for music learning. For example, Chinese patent ZL02202830.7 provides a music learning machine, which adopts the form of double keyboards, and realizes students' fingering imitation learning based on mechanical rotation to drive the sound wave cylinder to teach students. and other elementary learn...

Problems solved by technology

Chinese patent ZL02112135.4 discloses a multifunctional music learning machine, including a panel with several function keys, a host unit inside it, an auxiliary unit connected to the host unit, a music player unit, and a host unit There are recorded MIDI files stored on it and several functional modules that can be called to complete the functions corresponding to the function keys on the panel. This patent realizes music learning based on MIDI technology, but: (1) the combination of video and audio cannot be realized; ( 2) It only supports single-tone pitch discrimination, and cannot judge the pitch gate for complex polyphonic performances; (3) On the score system, there is no synchronization system between professional score system and MIDI score; (4) Music played based on MIDI Compared with real instrument performance, there are still obvious differences

[0003] In addition, due to the continuous enrichment of community cultural life, the number of pianos is also increasing. The following problem is: when playing or practicing the piano, the sound of the piano often interferes with the rest of neighbors or others, although some pianos now have special features. The middle pedal mute function is used for family practice, but in the dead of night, the sound of the piano will still disturb the rest of the neighbors
