That is, the microphone 10 receives the infant's voice (crying).
It detects the passing of surrounding sounds and outputs them to the filter circuit 11. The filter circuit 11 is the microphone 10
Only the frequency component corresponding to the infant's cry is extracted from the received audio signal and output to the amplifier circuit 12. The amplifier circuit 12 amplifies the audio signal from the filter circuit 11 and outputs it to the AD converter 13. The AD converter 13 converts the audio signal from the amplifier circuit 12 into digital data (audio data) and outputs it to a microcomputer (hereinafter referred to as microcomputer) 14, which will be described later.

The temperature sensor 15 detects the ambient temperature of the infant, such as room temperature,
A voltage signal corresponding to the ambient temperature is output to the amplifier circuit 16. That is, as the ambient temperature increases, the output voltage of the temperature sensor 15 increases, and conversely, as the ambient temperature decreases, the output voltage of the temperature sensor 15 decreases. Amplifier circuit 1
Reference numeral 6 amplifies the voltage signal from the temperature sensor 15 and outputs it to the AD converter 17. The AD converter 17 converts the voltage signal from the amplifier circuit 16 into digital data (temperature data).
It converts the data into a file and outputs it to the microcomputer 14.

The microcomputer 14 outputs the audio data from the AD conversion section 13 to the modulation circuit 18, and also converts the temperature data from the AD conversion section 17 into a frequency signal and guides it to the modulation circuit 18 (
output). That is, as shown in FIG. 3, when the value of the temperature data from the AD converter 17 increases, the microcomputer 14 outputs the oscillation frequency to the modulation circuit 18 to 8, and conversely, the temperature data from the AD converter 17 increases.
