Abstract: PROBLEM TO BE SOLVED: To provide an on-vehicle sound device having a speaker grille, which has a design surface provided on a front surface of a plane wave speaker unit with voice coils for left and right channels via a front space of predetermined volume, in which sounds of the left and right channels are not mixed in the front space by separating the front space into left and right. SOLUTION: A sound separation plate (rib) 45 is provided at the boundary part between left and right channels in a front space 35, a plane wave speaker unit 30 is fixed, facing passengers in a rear-seat, to a back face of a front-seat, a speaker grille 40 is arranged along an external surface of the back face of the front-seat, and the rib 45 is protruded from the speaker grille 40 towards an inside of the front space 35. Stereo feeling can be maintained since sounds of the left and right channels are separated in the front space 35 by the rib 45 and are not mixed to each other. COPYRIGHT: (C)2012,JPO&INPIT
