Abstract of the Disclosure An electronic chime for generating an aural tone comprising an oscillator, an input signal generator for the oscillator, the input signal generated thereby decaying from an initial value to a lower value. The oscillator includes a signal processor (i.e., an amplifier) with a feedback frequency generator connected to the input of the amplifier and being responsive to the output of the amplifier for impressing a desired frequency on the input signal to the amplifier. A speaker and a driver for the speaker are provided, the latter being responsive to the output of the oscillator so as to sound a chime-like aural signal whose amplitude (volume) decays at at predetermined rate while the frequency of the signal remains substantially constant.
