Embodiment 1

[0043] refer to figure 1 and figure 2, the input system includes a piano frame 10 and black keys 11 and white keys 12 arranged alternately on the piano frame 10, the upper surface of the black key 11 is provided with a black key finger pressing area 111, and the upper surface of the white key 12 is provided with a white key. The key finger pressing area 121, the lower surfaces of the black keys 11 and white keys 12 are provided with a magnetic force generator 2, and in this embodiment, the magnetic force generator 2 is a magnet.

[0044] Simultaneously, qin frame 10 is positioned at the below of magnetic force generator 2 and is installed with supporting plate 3 by screw, and the top side of supporting plate 3 is equipped with sensor collecting plate 4 by screw, and sensor collecting plate 4 is electrically connected to one side of magnetic force generator 2. A magnetic sensor 5 is connected, and the magnetic sensor 5 corresponds to the magnetic generator 2 one by one. Wher...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 lies in that the structure of the sensor acquisition board 4 is different. refer to Figure 5 , in the present embodiment, the sensor acquisition board 4 is set as two pieces, and the magnetic force sensor 5 corresponding to the magnetic force generator 2 on the black key 11 is positioned on one sensor acquisition board 4, and the magnetic force sensor 5 corresponding to the magnetic force generator 2 on the white key 12 The magnetic sensor 5 is located on another sensor acquisition board 4 , and the two sensor acquisition boards 4 are located on the same plane and both are electrically connected to the main control board 6 .

[0055] Therefore, the magnetic force generator 2 can be fixed in advance, and then the positions of the two sensor acquisition boards 4 can be adjusted respectively, so as to improve the convenience of debugging and installation.

Embodiment 3

[0057] The difference between this embodiment and Embodiment 1 lies in the way the magnetic force generator 2 is fixed to the black keys 11 or white keys 12 . refer to Image 6 , in this embodiment, one side of the magnetic force generator 2 is vertically fixed with a threaded post 72, and the threaded post 72 penetrates into the black key 11 or the white key 12 from bottom to top along the vertical direction, and the threaded post 72 and the black key 11 or The white key 12 is screwed, and the upper surface of the magnetic force generator 2 is attached to the lower surface of the black key 11 or the white key 12 .

[0058] Compared with Embodiment 1, the advantage of this embodiment is that the installation of the magnetic generator 2 is more stable, and it is convenient for disassembly and replacement.

Abstract

The invention relates to a keyboard instrument digital input system, comprising a musical instrument frame, and black keys and white keys which are arranged on the musical instrument frame. Black key finger pressing areas are arranged on the upper surfaces of the black keys, and white key finger pressing areas are arranged on the upper surfaces of the white keys. Magnetic force generators are arranged on the lower surfaces of the black keys and the lower surfaces of the white keys. A sensor acquisition board is arranged on the musical instrument frame and below the magnetic force generators. Magnetic force sensors in one-to-one correspondence with the magnetic force generators are arranged on the side, facing the magnetic force generators, of the sensor acquisition board, and the magnetic force sensors are electrically connected with the sensor acquisition board. A main control board is arranged on the musical instrument frame, the main control board is electrically connected with the sensor acquisition board, and the main control board is electrically connected with rear-end equipment. According to the system, the accuracy of moving the magnetic force generators to the positions of the magnetic force sensors is greatly improved, so that the measurement accuracy of the movement speeds of the magnetic force generators can be effectively improved, and the measurement accuracy of the key pressing forces when the keys are pressed, namely the measurement accuracy of the loudness of the piano sound when the corresponding keys are pressed, in the system is improved.

Description

technical field [0001] The present application relates to the field of musical instruments, in particular to a digital input system for keyboard musical instruments. Background technique [0002] The sounding principle of traditional piano is to produce sound through physical percussion, so one of the advantages of traditional piano is that different timbres can be played through different percussion strengths, so as to create beautiful music. The sounding principle of the electronic keyboard is to use the keys as the control switch, rely on various audio chips to synthesize the sound, and play the music through the speaker unit. [0003] Among them, the shortcomings of the traditional piano are fixed tone, single function, and the sound cannot be eliminated when playing, which is easy to disturb the people. The advantages of the electronic piano can make up for the shortcomings of the traditional piano. Therefore, how to give the advantages of the electronic piano to the tr...
