DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a vehicle-mounted box speaker as a whole, and the box speakers 2R and 2L for the right and left channels form an integrated speaker system.

That is, the right and left channel box speakers 2R and 2L are the speaker cabinets 10R and 10L, respectively, for the high-frequency reproduction speakers 4R and 4L, the middle-frequency reproduction speakers 6R and 6L, and the low-frequency reproduction speakers (that is, woofers). 8R and 8L are housed, and as shown in FIG. 2, they are arranged on the left and right sides of the rear tray of the vehicle.

At this time, in the right and left channel box speakers 2R and 2L, the high-pitched sound reproducing speakers 4R and 4L, the mid-tone sound reproducing speakers 6R and 6L, and the low-pitched sound reproducing speakers 8R and 8L are arranged inward from the left and right ends. It is designed to do. Further, the high-pitched sound reproducing speakers 4R and 4L and the medium-tone reproducing speakers 6R and 6L are arranged on the front side of the speaker cabinets 10R and 10L so as to be inclined at an angle of about 60 degrees with respect to the rear tray. Has been done.

Thus, in the right and left channel box speakers 2R and 2L, the speaker 4R to 6L are simply arranged on the rear tray and held so that the opening directions of the speakers 4R to 6L face forward, and the directivity of the speakers 4R to 6L is maintained. It is designed so that the playback sound of high quality can be auditioned by effectively utilizing it.

A speaker 4 for reproducing high-pitched sound having a stronger directivity.
By arranging R and 4L outside, it is possible to listen to a stereo reproduction sound having a high sense of presence.

In the speaker cabinets 10R and 10L, when viewed from the front, the speakers 4R and 4L for high-pitched sound reproduction arranged on the outside to the speakers 6R and 6L for middle-tone reproduction arranged inside the speakers 4R and 4L, respectively.
The outer shape is formed so as to gently rise in accordance with the diameter of 6 L, thereby ensuring the rear view and reducing the volume occupied on the rear tray.

On the other hand, in the bass reproduction speakers 8R and 8L, the speaker cabinets 10R and 10L are used.
Speakers 8R and 8L with respect to the rear tray mounting surface of L
Are arranged so that their radial directions are substantially parallel to each other. Corresponding to this, the speaker cabinet 10R
10L and 10L, the outer shape rising from the outside falls at the mounting position of the speakers 8R and 8L so that the opening portions of the speakers 8R and 8L are below the uppermost ends of the speaker cabinets 10R and 10L. Is done.

As a result, in the right and left channel speaker speakers 2R and 2L, when viewed from the front,
The shape of the speaker cabinets 10R and 10L is reduced in the central portion of the rear tray so that the deterioration of the rear visual field can be effectively avoided.
Since the directivity of bass is low, even when the bass reproduction speakers 8R and 8L are arranged upward, it is possible to effectively avoid the sound quality deterioration of bass.

In practice, this type of woofer can be used as a speaker 4R ...
When it is tilted at the same angle as 6L, the rear projection area increases by the amount indicated by the alternate long and short dash line in FIG. Thus, by arranging the low-pitched sound reproducing speakers 8R and 8L upward, as described above, even if the diameters of the speakers 8R and 8L are increased,
It is possible to effectively avoid the deterioration of the rear view, and to improve the sound quality of bass by increasing the diameters of the speakers 8R and 8L accordingly.

In this embodiment, the speaker cabinets 10R and 10L are formed so that their shapes change smoothly from the mid-range reproduction speakers 6R and 6L to the low-range reproduction speakers 8R and 8L. The outer shape projections of the box speakers 2R and 2L are reduced and the design is improved.

According to the above construction, by arranging the low-pitched sound reproducing speakers 8R and 8L in the upward direction, it is possible to effectively avoid the deterioration of the rear view even if the diameters of the speakers 8R and 8L are increased. The bass can be improved by enlarging the diameter of the speaker without hindering the rear view.

In the above embodiment, when viewed from the front, the outer shape of the speaker cabinet extends from the high-pitched sound reproducing speakers 4R and 4L arranged outside to the middle-tone reproducing speakers 6R and 6L arranged inside thereof. The case where the shape is gently raised has been described, but the present invention is not limited to this, and can be widely applied to speaker cabinets of various outer shapes.

In this case, as shown in FIG. 3, for example, even when the upper portion of the speaker cabinet is formed flat, the rear projection area can be improved as compared with the conventional arrangement shown by the one-dot chain line. It is possible to secure a rear view and improve sound quality.

On the other hand, as shown in FIG. 4, even when the positions of the speakers are exchanged, the deterioration of the rear visual field can be effectively avoided.

[0023]

As described above, according to the present invention, by arranging the low-pitched sound reproducing speaker upward, it is possible to improve the low-pitched sound by increasing the diameter of the speaker without obstructing the rear view. Can be obtained.
