Abstract: An electronic wind instrument is provided with a processor (CPU 5) and plural touch sensors (a detecting unit 12s and detecting units 13s) disposed along a first direction. A first output variable da/dt is obtained, representing a variation per unit time of an output value from a first sensor (detecting unit 12s) in the plural touch sensors disposed on the side close to first end (tip side) in the first direction. A second output variable dS/dt is obtained, representing a variation per unit time of a sum of output values from second sensors (detecting units 13s) disposed between a second end (heel side) and the first sensor in the first direction. The processor judges based on the first output variable da/dt and the second output variable dS/dt whether a tonging process should be performed.

Abstract: A driving device is provided with: a power circuit in which it is possible to modify an output current value of an output terminal configured to have a load connected thereto; an output capacitor connected between the output terminal of the power circuit and a reference potential node; a switching element connected between the output terminal of the power circuit and the reference potential node; and a control unit that controls the output current value of the power circuit.The control unit turns the switching element ON and OFF and controls the output current value of the power circuit during a period in which the switching element is ON such that the voltage of the output terminal of the power circuit during this period is equal to or lower than the voltage applied to the load during a period when this load is OFF.
