を行うセグメント表示部と、 を有する警告表示装置。[Claims for Utility Model Registration] A sound detection circuit that detects external sound, a low-pass filter that removes predetermined harmonic components from the sound signal detected by the sound detection circuit, and a reference signal generator that generates a reference signal. a count synchronization counter capable of counting the reference signal from the reference signal generation circuit and synchronizing the counting timing in response to the generation of the sound signal output from the low-pass filter; and a digit of the count synchronization counter. a shift register that sequentially stores the sound signal from the low-pass filter as data in response to each occurrence of a rising signal; and a detection circuit that outputs different detection signals at fixed time intervals corresponding to the contents stored in the shift register. A warning display device comprising: a decoder that creates a display signal in response to a detection signal from the detection circuit; and a segment display section that displays a direction based on the display signal from the decoder.
