Claims

[Claims for Utility Model Registration] A microphone, a low-pass filter that receives the audio signal from the microphone, a voice storage and synthesis circuit that records and synthesizes the voice signal from the low-pass filter, and this voice storage and synthesis circuit. a timing signal generation circuit that generates a timing signal when storing an audio signal; an acoustic signal generation circuit that generates an acoustic signal with a frequency higher than the cutoff frequency of the low-pass filter in accordance with the timing signal from the timing signal generation circuit; a sound emitting means, and when the sound signal is stored in the sound storage and synthesis circuit, the sound signal generating circuit and the sound emitting means are connected;
An audio storage circuit comprising: a switching circuit that connects the audio storage synthesis circuit and the sound emitting means when audio signals are synthesized in the audio storage synthesis circuit.
