Specifically, the first touch pad 200 is a touch pad for adjusting the pitch, for example, in the touch area, the pitch is adjusted from bottom to top and gradually increases; the second touch panel 300 is a touch panel for adjusting vibrato, and for example, in a touch area, the vibrato is adjusted to be gradually increased from bottom to top. In practical applications, the first touch panel 200 generates a first touch signal based on a touch operation applied thereto, and the touch panel circuit 400 generates a pitch signal based on the first touch signal; the second touch panel 300 generates a second touch signal based on a touch operation applied thereto, and the touch panel circuit 400 generates a tremolo signal based on the second touch signal. It should be noted that the pitch tuning based on the first touch pad 200 and the vibrato tuning based on the second touch pad 300 may be performed simultaneously or separately, which is not limited in this embodiment.
The first touch panel 200 and the second touch panel 300 are capacitive touch panels, and capacitance changes can be caused when a touch action occurs in the capacitive touch panels; the capacitance change of the touch panel circuit 400 is converted into a voltage or current change, and then the voltage or current change is subjected to analog-to-digital conversion to obtain MIDI information, so that the subsequent pitch-adjusting operation or vibrato-adjusting operation is performed according to the MIDI information. It should be noted that, the analog-to-digital conversion of the voltage or current change to obtain MIDI information is the same as the signal processing method of the prior electronic musical instrument when the pitch and/or vibrato is adjusted by using the bending wheel and/or the modulating wheel, and is not described here again.
