A predetermined musical tone, that is, a musical tone of a scale corresponding to the exhalation hole 11 is emitted.

For example, when breathing through the intake hole 12, the magnet 21 rolls in the intake hole 12 due to the air flow caused by the intake, and moves the roller 22 onto the fixed contact 20, causing the fixed contact 20 to move. Make it conductive and output a contact signal. As described above, this contact signal is input from the eight-monica main body 10 to the QPU 26 as the scale designation signal 23 corresponding to the fixed contact 20, and is output to the speaker section 8 via the musical tone creation section 27 and the amplifier section 28, and is outputted to the speaker section 8 to a predetermined value. This musical tone is produced from the speaker unit 8.

Furthermore, in the above-mentioned electronic musical instrument, when electronic harmonica 1 and mini key AM child instrument 2 are operated at the same time, 1
Each signal 26.24 from harmonica main body 10 and keyboard section 5
is input to 0PU26, musical tone creation section 27, amplifier section 28
Each musical tone is simultaneously emitted from the speaker section 8 via the speaker section 8.

Therefore, for example, if you play a melody on m child harmonica 1,
Accompaniment can be performed at the same time on the keyboard section 5, and a good performance can be performed.

In this way, according to the above electronic harmonica 1, since breathing is used as an input means, even beginners can easily and easily perform the input performance using the same rendition technique as a natural musical instrument using the conventional respiration rendition method.

Next, another embodiment of the present invention will be described based on FIG. 4. This embodiment is an exhalation hole 61 of an electronic harmonica 6o.
