Multi-Key Electronic Music Instrument

A multi-key electronic music instrument, comprising:

• a main body including at least seven operational keys and at least one functional key disposed thereon, each of the operational keys having a first conduction portion and the functional key having a second conduction portion, the seven operational keys respectively corresponding to music notes of Do, Re, Mi, Fa, So, La and Si in a diatonic scale, and the seven operational keys being distributed in at least two rows;
• and
• a circuit board having an integrated circuit (IC), the circuit board being disposed in the main body and comprising at least seven first electrical connection points respectively corresponding to the first conduction portions of the operational keys and at least one second electrical connection point corresponding to the second conduction portion of the functional key, the integrated circuit saving at least seven electronic sounds corresponding to the music notes of Do, Re, Mi, Fa, So, La and Si in a diatonic scale, and a plurality of functional programs;
• wherein each of the first electrical connection points corresponds to at least one of the music notes and the second electrical connection point corresponds to the functional programs, when the first conduction portion of one of the operational keys electrically contacts with the corresponding first electrical connection point, the integrated circuit generates the electronic sound of the corresponding music note, and when the second conduction portion of the functional key electrically contacts with the corresponding second electrical connection point, the integrated circuit executes at least one of the functional programs.
