  • US2015/0101477 discloses an electronic flute that comprises a PCB that supports a plurality of proximity sensors disposed in the holes of the body of the flute.
  • the PCB is disposed inside the tubular channel defined by the body of the flute. Obviously, the PCB interferes with the air that flows in the channel of the flute and negatively affects the sound emitted by the flute.
  • US2015/0101477 discloses infrared LEDs that have no signaling function and does not disclose the possibility of using pressure sensors and inclination sensors.
  • US2006/0283312 discloses a wind instrument, such a transverse flute, which is substantially different from the recorder.
  • a wind instrument such as a transverse flute, which is substantially different from the recorder.
