Abstract

PURPOSE:To electrically absorbe deviations of mechanical resonance frequencies by making driving frequencies of an electro-acoustic transducer plural and making one of them suitably selectable. CONSTITUTION:A frequency dividing circuit 5 for alarm driving frequencies is constituted by T type FFs 4 stages. Then, the output of an oscillation circuit 1 is inputted to a frequency dividing circuit 2, which in turn outputted as time counting or control signal. This is then inputted to the other input end of an AND gate 3 to whose on input end is inputted an alarm coincidence signal A. The output of the AND gate 3 is inputted to the frequency dividing circuit 5 for alarm driving frequencies and the Q output of the final stage of the frequency dividing circuit and the F output of a decoder 14 are inputted to an OR gate 13 to which the Q output of the third stage thereof is inputted. An alarm driving signal is then outputted therefrom. Hence, applying of a suitable signal level to decode mode selecting terminals B, C makes possible driving of the electro-acoustic transducer being a sounding means at the optimum alarm driving frequency and the mechanical deviations of the frequencies from the central frequency are electrically absorbed.
