Title: Coil driving tact type electronic metronome
Inventor: NAGASAKA NOBUYUKI
IPC: G04F5/02
Filed: 1987-02-27
Abstract: PURPOSE:To hold the deflection angle of a tact constant by varying the amplification factor of a variable gain amplifying driver according to the tempo of a metronome. CONSTITUTION:A tempo generation part 1 generates the tempo clock of the metronome at set tempo to generate a tempo clock 6, and a set tempo quantity is outputted as a tempo quantity information signal 8. A coil driving signal generation part 2 receives the signal 6 of the generation part 1 to generate a waveform with a period synchronized with the signal 6, thereby outputting it as a coil driving circuit 7. The variable gain amplifying driver part 3 controls the amplitude of the signal 7 according to the signal 8 and the tact deflection angle of the coil driving tact part 5. Namely, when the deflection angle of the tact is small because the tempo of the metronome is fast, the amplification factor of the driver 3 is increased with the signal 8, but when the tempo of the metronome is slow and then deflection angle of the tact is large, the amplification factor of the driver 3 is decreased to hold the deflection angle of the tact constant.
