することを特徴とする電子メトロノーム。 An electronic metronome that sets the tempo in an analog manner is equipped with two resistors that constitute a time constant that determines the oscillation frequency, and a diode that switches the time constant depending on whether the output signal is positive or negative. The tempo setting circuit consists of a tempo setting variable resistor that changes only a constant, a tempo sound generation circuit that generates a tempo sound based on the output of the tempo setting circuit, and an LED light emitting circuit. An electronic metronome that uses a resistor to oscillate a rectangular wave with a different duty corresponding to a set tempo number.
