PURPOSE: To provide an interior sound reproducing device which locates images at the respective centers of a driver's seat and an assistant driver's seat.

CONSTITUTION: Speakers 9 and 10 of lower and middle frequency range are internally packaged in front doors 7 and 8 at both sides, and a first and a second dipole sound source 11 and 12 are mounted on a dash-board 3 while being aligned with the respective extension lines of the center lines of a driver's seat 5 and an assistant driver's seat 6. The first dipole sound source 11 is made up of horn speakers 11a and 11b which are located back to back, and the second dipole sound source 12 is similarly made up of horn speakers 12a and 12b. Therefore, when signals R are inputted into the speakers 9 and 10, and when signals R, -R, -L and L are inputted into L high frequency range horn speakers 11a, 11b, 12a and 12b, sound from the horn speakers 11a and 12a reaches the driver's seat 5 and the assistant driver's seat 6 while being reflected by side windows 7a and 8a, and sound from the horn speakers 11b and 12b reaches the driver's seat 5 and the assistant driver's seat 6 while being reflected by a front window 4. By this constitution, images are thereby located at the respective centers of the driver's seat and the assistant driver's seat.
