PURPOSE:To resolve rationally the spatial problem and a structural problem for speaker fitting by separating a front speaker into speakers for a low acoustic band and a high acoustic band and by installing them in positions proper to the rider respectively. CONSTITUTION:A front speaker is separated into speakers provided on instrument 3 and speakers provided on doors or dash sides 5, 5 in both sides of the car, and speakers 7, 7', 9, 9', 10 and 10' to reproduce middle and high acoustic bands are provided on instrument 3, and speakers 8, 8', 11 and 11' to reproduce the low acoustic band are provided on doors or dash sides 5, 5. As the result, the sound of the low acoustic band reproduced by speakers on front doors or dash sides 5, 5 has a wide directivity of the low sound, so that powerful feeling, etc., of the low sound can be given perfectly. Then, the sound of middle and high acoustic bands reproduced by speakers on the instrument is heard from the front, so that a good-quality sound can be reproduced throughout a wide frequency range from the low sound to the high sound. |
