Embodiments of a method and an apparatus for controlling power of an external device in an audio receiver can reduce unnecessary power consumption of the external device. The apparatus can detect a potential, a level or the like of a speaker output signal from the audio receiver and control the power of an external device coupled to the audio receiver, such as a Bluetooth transmitter module, on the basis of the detected potential, level or the like. Therefore, the power of the external device can be directly controlled without a separate manual operation. Further, the apparatus can be simply and conveniently implemented using only the speaker output signal of the audio receiver, without the addition of a separate signal line. |
