Abstract
A sound reproducing apparatus capable of self-diagnostic. The apparatus includes a directional speaker emitting ultrasound waves to a target object, an information acquisition unit configured to acquire a sound from the target object and optionally an image of the target object, and a processor electrically connected with the directional speaker and the information acquisition unit. The processor drives the directional speaker to emit the ultrasound waves to the target object and diagnoses a failure of the directional speaker based on the sound acquired by the information acquisition unit. A self-diagnostic method for a sound reproducing apparatus having a directional speaker is also provided.
