A speaker(130) generally has impedance of 4Ω or 8Ω, and the impedance is changed according to the change of the frequency and power inputted to a speaker. A failed state of a speaker is determined by using the difference of the impedance changed according to the frequency or the power, and the fault detection circuit(140) measures the impedance of the signal input terminal inputted to the speaker. The fault detection circuit measures the impedance of the test signal having the specific frequency.
