DESCRIPTION JPS548931
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of
the present invention, FIG. 2 is a cross-sectional view taken along the line 1--2 of FIG. 1, and FIG.
3 is a cross-sectional view taken along the line 2--2 of FIG. 4 and FIG. 4 show the speaker
mounting plate 2 in any direction (up and down) in the state of FIG. 2 with the direction of the
speaker 3 changed, and FIG. 5 shows the speaker mounting plate 2 in the state of FIG. It is the
figure which changed direction of the speaker 3 toward arbitrary directions (right and left). 1 ......
speaker box, 2 ...... speaker mounting plate, 3 ...... speaker.
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an on-vehicle
speaker. Since the conventional in-vehicle speaker is fixedly provided in the speaker box, there is
a disadvantage that the direction of the sound emitted from the speaker is constant and the
sound effects can not be formed according to each single room. It is an object of the present
invention to provide an on-vehicle speaker box which eliminates the above-mentioned
disadvantages of the prior art and makes it possible to manufacture an acoustic effect structure
suitable for each vehicle interior. In order to achieve this purpose, the speaker is fixed to a
speaker mounting plate, and the speaker mounting plate is rotatably attached to the speaker box
by 11L. ? The present invention will now be described by way of an embodiment shown in FIGS.
In each drawing, reference numeral 5 denotes a speaker fixed to the speaker mounting plate 2,
and the entire circumference of the speaker mounting plate 2 and the contact surface of the
speaker box 1 with the speaker mounting plate 2 are in contact in a spherical shape. Thus
configured, the speaker mounting plate 2 can be oriented in any direction. Therefore, it is
possible to harm the optimum acoustic effect building depending on the individual cabin.
