摘要： An audio apparatus includes: a connector that supports a multipolar plug including a plurality of plug terminals, the connector having a plurality of connector terminals including an input terminal of an audio collection section and an output terminal that outputs a noise canceling signal; a signal amplification section that amplifies a combined signal generated by combining the noise canceling signal and a reproduction audio signal, the signal amplification section being provided on an audio signal line that connects the input terminal and the output terminal; a detection section that detects whether the multipolar plug is inserted or pulled out by detecting change of voltage of a voltage supply line connected to the audio signal line; and a suppression section that suppresses output from the signal amplification section when the multipolar plug is pulled out but does not suppress the output when the multipolar plug is inserted.
