Abstract

PURPOSE:To control power consumption so that an acoustic signal being intermittent at short time intervals can be connected and generated smoothly. CONSTITUTION:This circuit is provided with a generating means 1 of an acoustic signal which starts its operation by a start signal, an operation continuing signal generating means 2 for showing that sais means is being operated, a time limiting means 3 for starting its operation immediately before an operation continuing signal outputted from the means 2 is stopped, after said means 1 has ended its operaton, and a means 4 for taking OR of a time limiting signal for showing that the time limiting means 3 is being operated, and the operation continuing signal for showing that the means 1 is being operated, and an operation or non-operation of a loudspeaker driving circuit 5 is controlled by an output of the means concerned 4.
