<p>PROBLEM TO BE SOLVED: To provide an acoustic signaling module which can be integrated in an electric apparatus for domestic use or the like at low cost and easily.SOLUTION: A microcomputer 2 and an encoder 3 are configured as an acoustic signaling module 1 including: a sensor signal input terminal 4 and a trigger signal input terminal 5 connected to the microcomputer 2; and an acoustic signal output terminal 6 connected to the encoder 3. The acoustic signaling module 1 is integrated into a thermometer 10, a sensor of the thermometer 10 and the sensor signal input terminal 4 are connected, and a trigger signal output terminal of an apparatus control part 12 and the trigger signal input terminal 5 are connected. An alarm tone output terminal of the apparatus control part 12 and the acoustic signal output terminal 6 are connected. When a temperature measured by a sensor is stabilized, the apparatus control part 12 outputs an alarm tone and outputs a trigger signal. The microcomputer 2 codes/encrypts a detection signal of the sensor synchronously with the trigger signal, and the encoder 3 encodes the coded signal into an acoustic signal of a non-audible band and outputs the acoustic signal.</p> |
