摘要
An inspection signal generator of an acoustic device outputs a first inspection signal. An amplifier receives a first reference signal, and outputs a second inspection signal according to the first inspection signal. A first detector is electrically connected to an output side of the amplifier, and outputs a first detection signal based on the second inspection signal. The first detector is electrically connected to the output side of the amplifier, and outputs the first detection signal based on the second inspection signal. A determiner compares a first detection signal output from the first detector with a preset determination reference signal so as to detect electrical abnormality between a ground terminal and an output terminal electrically connected to the output side of the amplifier.
