Abstract:
A memory previously stores, as reference impedance characteristics, frequency characteristics of impedance of the speaker during a normal operating state of the speaker. During use of the speaker, a detection circuitry detects, as current impedance characteristics, frequency characteristics of impedance of the speaker on the basis of a real-time audio signal being supplied to the speaker. A determination circuitry determines presence/absence of an abnormality of the speaker on the basis of comparison between the detected current impedance characteristics and the stored reference impedance characteristics. Thus, it is possible to check the operation of the speaker based on of the real-time audio signal without using any dedicated test signal. In this way, it is possible to detect presence/absence of an abnormality of the speaker on the basis of a real-time audio signal being supplied to the speaker, for example, during an actual performance in a concert.

Claim (Index 6):
The speaker operation checking device as claimed in  claim 1 , which further comprises a current memory that stores the current impedance characteristics detected by the detection circuitry, the current impedance characteristics stored in the current memory being updated with current impedance characteristics detected last by the detection circuitry, and\n wherein when the real-time audio signal being supplied to the speaker is equal to or smaller in level than a predetermined threshold value, the current impedance characteristics stored in the current memory are not updated.
