The present invention relates to an audio device for a vehicle. The purpose of the present invention is to maintain a constant balance of volumes of speakers supplied to passengers all the times regardless of positions of the passengers by differentially adjusting the volumes of the speakers according to the positions, a movement direction, and a movement amount of the passengers and improve a three-dimensional acoustic effect and quality of sounds supplied to the passengers. To achieve the same, the audio device for a vehicle including an audio body installed on a front panel of a driver and multiple speaker outputting audio signals inputted into the audio body and outputting the audio signals inside a vehicle indoor space includes a matrix infrared rays image sensor sensing infrared rays emitted from the passengers by photographing the vehicle indoor space and dividing the images of the vehicle indoor space into image cells in a matrix form; an analysis unit analyzing information on the positions of the passengers using the image cells in which the emission of the infrared rays is sensed among the image cells of the vehicle indoor space inputted by the matrix infrared image sensor; and a control unit automatically and differentially adjusting the volume of each speaker according to the positions of the passengers inputted by the analysis unit.
