发明名称 Electronic metronome equipped with subtraction timer
摘要 An electronic metronome comprises circuitry for setting a desired tempo, a circuit for generating a tempo signal corresponding in time to the desired tempo, circuitry for setting a desired time period and a circuit for generating a time-up signal corresponding in time to the end of the desired time period. A sound generator receives the tempo signal and the time-up signal for generating a tempo sound for each tempo signal and a time-up sound for the time-up signal. A control circuit terminates the generation of the tempo sounds after the generation of the time-up sound.
