Problems solved by technology

[0002] Known electronic musical instruments or musical instrument devices, such as electronic pianos, musical instrument digital interface (Musical Instrument Digital Interface, MIDI) keyboards or percussion controllers, include a plurality of sensing units, namely touch keys or pads, which can be played or knocked by external force. The electric signal is generated by the strike, and then sent to the signal processing unit to be converted into a corresponding digital control signal. The control signal can represent information such as pitch, strength, and sound shape, and then the digital control signal can be output to the sound generator or computer. , then the corresponding analog sound signal is output by the sound source device or computer, and the mapping relationship between its keys and phonemes is mostly modeled on the key arrangement method of a traditional piano, and the phonemes mapped to twelve equal temperaments from white keys include: C( note names), D, E, F, G, A, and B, while the black keys map to the sharp or flat chromatic scale adjacent to the white key: C# (Db), D# (Eb), F# (Gb), G# (Ab) and A#(Bb), because there is a half-tone difference between white keys B and C, or E and F, then there is no setting of black keys, causing the mapping relationship between the described MIDI keyboards to be unable to arbitrarily change the key positions and phonemes. The mapping order of phoneme C, D, E, F, G, A, B of former white key is changed into A, B, C, D, E, F, G, then C# (being Db) and G# (being Ab) The new mapped phoneme lacks a corresponding black key

Embodiment Construction

[0010] The invention discloses a musical instrument device, which arranges a plurality of sensing units on a platform in a two-dimensional arrangement and combination, and the relationship between each sensing unit and phoneme mapping can be adjusted and changed according to the needs of music or players. The characteristic advantages and spirit of the present invention are further clarified through the following detailed description of the invention and the accompanying drawings.

[0011] Implementation Example 1: Please refer to figure 1 , a musical instrument device is installed on the platform (P1) with three groups of in-line induction groups: GR1, GR2 and GR3, each group of induction groups contains eleven induction units in a row on the left: numbered L(I, J), where I =1, 2 or 3; J=1 to 11, and eleven in-line induction units on the right: numbered R(I, J), where I=1, 2 or 3; J=1 to 11, three groups of in-line The induction group has sixty-six induction units in total, ...

Abstract

The invention discloses a musical instrument device. The musical instrument device comprises several columns or rows of sensors mounted on a panel. The mapping note of a sensor is semitone higher or lower than that of the neighboring sensor. There are some sensors are mapped as 'blank', and certain different sensors are mapped to the same note. The musical instrument device is portable, and easy to play quickly owing to the novel compact layout of the sensors on the panel.

Description

technical field [0001] The invention relates to a musical instrument device. The device includes a plurality of induction units installed on a platform. When the induction units are subjected to external forces, corresponding signals can be generated, and then output to the sound generating unit to generate corresponding sounds. Background technique [0002] Known electronic musical instruments or musical instrument devices, such as electronic pianos, musical instrument digital interface (Musical Instrument Digital Interface, MIDI) keyboards or percussion controllers, include a plurality of sensing units, namely touch keys or pads, which can be played or knocked by external force. The electric signal is generated by the strike, and then sent to the signal processing unit to be converted into a corresponding digital control signal. The control signal can represent information such as pitch, strength, and sound shape, and then the digital control signal can be output to the sou...
