Claims

[Scope of utility model registration request]

In addition to being connected to the start signal generation circuit,
One AND circuit is connected to the pulse oscillator and is activated by the start signal output from the start signal generation circuit to output the pulse output from the pulse oscillator to the OR circuit. another AND circuit connected to the oscillator and actuated by a signal from the flip-flop circuit to output the pulse output from the pulse oscillator to the OR circuit; and on the other hand, connected to the one and other AND circuits. On the other hand, an OR circuit is connected to the counter and outputs the pulse input from another AND circuit as an input signal to the counter, and the pulse input from the OR circuit changes the frequency from 0 to a predetermined local maximum value. a counter that sends a clock signal to the flip-flop circuit when the count value changes from 0 to 1, and sends a reset signal to the reset pulse generator when the count value reaches the maximum value; a flip-flop circuit connected to the AND circuit of the counter and holding the clock signal from the counter and outputting it as a start signal to the other AND circuit; and a flip-flop circuit connected to the counter and the flip-flop circuit, into which the reset signal is input. a reset pulse generator that outputs a reset pulse that resets the counter and the flip-flop circuit to stop outputting the start signal; a storage device that is connected to the counter and stores data of the start sound; a digital-to-analog converter that is connected to a counter that is operated by a counter that receives the above-mentioned data stored in a storage device as an input signal, and a speaker that amplifies the above-mentioned output signal appropriately and outputs a start sound consisting of an electronic sound. An electronic starter characterized by comprising:
